The invention relates to an agricultural seeding machine, in particular to a straw crushing and inter-furrow collecting-mulching no-tillage seeder. A straw-crushing device, a guide device, a fertilizer discharging device, and a furrowing and seeding device are sequentially arranged on a rack from front to back. According to the guide device, a plurality of straw-crushing guide assemblies having installation positions capable of being horizontally adjusted are arranged on an adjustment crossbeam, are in a prow shape, and each consist of a rear vertical back plate formed with a fertilization port, and two front symmetrical oblique guide plates. Straw is orderly spread on straw mulching belts between seeding belts while being crushed within the working range, and thus, the seeding belts are free of straw obstacles. The straw crushing and inter-furrow collecting-mulching no-tillage seeder is high in working integrity, easy to assemble, and low in energy consumption.

An air seeder cart has a fill auger pivotally mounted to the frame of the air seeder cart and moveable to position the fill auger for filling seed hoppers. The swivel joint for the air seeder has a brake assembly biased by a spring to prevent movement in the absence of an input. A remotely positioned lever and cable assembly unlock the brake assembly for movement to a new position upon an operator input to the lever.

An ultra high-pressure liquid jet soil processing system of an agricultural implement is provided. The ultra high-pressure liquid jet soil processing system includes a frame, an ultra high-pressure liquid pump disposed on the frame, a set of ultra high-pressure lines fluidly connected to the ultra high-pressure liquid pump, and at least a first liquid jet soil implementation head and a second liquid jet soil implementation head fluidly connected to the ultra high-pressure liquid pump via the set of ultra high-pressure lines. The first and second implementation heads are configured to condition soil for seed deposition by generating a plurality of trenches.

Optional attachments, such as a drop seeder and a sprayer unit, can be removably attached to the front plate of a turf aerator. The attachment includes a hitch slideably received in a tubular receiver and pinned therein by a pin. A lock is pivotal relative to the attachment from an unlocked position to a locked position with the front plate received in slots of the lock. The lock is pivoted relative to the attachment by a rod which is threadably received in the hitch. Valve openings in a valve plate are aligned or mis-aligned with lower openings formed in a hopper mounted to the hitch by a linear electric actuator. A lever is pivotably mounted to a housing which is removably attached to the chassis of the turf aerator and activates the linear electric actuator and a switch controlling an agitator. A valve is alternately in fluid communication with a spray nozzle mounted relative to the hitch and a spray wand. A switch mounted to the chassis is electrically connected to a motor driving a pump in fluid communication with a tank and the valve.

A mobile machine includes a frame, and a set of wheels supporting the frame. The mobile machine also includes a set of ground-engaging tools mounted to the frame that are movable relative to the wheels to change a depth of engagement of the ground engaging-tools with ground over which the mobile machine travels. A sensor senses the ground surface over which the mobile machine is traveling. The sensor can do this by sensing the position of a ground-following device having a proximal end coupled to the frame and a distal end configured to engage a surface of the ground and follow the surface of the ground as the mobile machine moves in a direction of travel, or by sensing the surface of the ground behind a surface cleaning device that exposes the surface of the ground to the sensor.

Disclosed is an aperture assembly for use with a subsurface ejection vessel that includes an electromagnet, a first dynamic aperture (309C), a second dynamic aperture, a hollow shaft injection drill bit (1711), a third dynamic aperture (807C), collar perforations (607B), and closed window apertures (907A, 907B, and 907C). The electromagnet actuates a closing of the first dynamic aperture (309C). The electromagnet actuates an opening of the second dynamic aperture. The third dynamic aperture (807C) dynamically opens when triggered by a first pre-determined depth achievement counting by the encoder (1605B) of the lead screw (1713) or distance traveled by a platform (505A) triggered by the limit switch (1707) that are communicated to the AI robot (1407C), the computer (1411C), and the PLC (1405C). The third dynamic aperture (807C) dynamically opens when the camera lens (1503) has a second pre-determined depth penetration of the hollow shaft injection drill bit (1711) and that the limit switch (1707) information is communicated to the computer (1411C), or the PLC (1405C). The collar perforations (607B) enable pushing sub-surface constituents and soils away from either collar apertures, or collar windows. The closed window apertures (907A, 907B, and 907C) perform closure during descent to prevent soil penetration into the hollow shaft injection drill bit (1711). The closed window apertures (907C) during descent to prevent soil penetration into the hollow shaft injection drill bit (1711).

A tilling apparatus and a method of tilling soils which includes the use of a rotational shaft having a number of cutter assemblies located at spaced apart locations on the shaft in which each cutter assembly has a multitude of blades which rotate as the rotary shaft rotates to form a plurality of spaced apart trenches having the same spacing as the spacing of the cutters, and a width caused by the width of the blades. As the blades dig the trench, the soil contacted by the blades is granulated and is tossed about by the spinning blades so that some soil falls back into the trench and some falls along the periphery of the trench to form rows of aerated granules which promote enhanced growth of plants or seeds in the trench and along the edge of the trench to improve the yield of pasture having the trenches. Various attachments can be provided on the tilling apparatus, either in front of or towards the rear of the spinning blades for different purposes, such as rippers, seeders, levellers, or similar. The advantage of the tilling apparatus is that the soil is formed into granules which are used to form an aerated array of soil granules having enhanced growing properties for plants.

A soil conditioner spreader and an operation method thereof are provided. The soil conditioner spreader includes a spreader body, a ridger, a solid tank, two spiral drills, a rotary tillage wheel and a mulching device, where the spreader body is provided with a hopper in a front part. The hopper stores a conditioner. The solid tank is arranged above the spiral drills. The spreader body is connected to the solid tank through a feeding track. The ridger, the spiral rills, the rotary tillage wheel and the mulching device are successively arranged at the bottom of the spreader body from the rear to the front. The ridger ridges first, and then the spiral drills perform deep plowing, rotary tillage and scarification and apply the conditioner to a ridge. The rotary tillage wheel performs rotary tillage, and a nozzle sprays a nutrient solution or an herbicide/insecticide. Finally, the mulching device mulches.

A covering soil mulching apparatus according to an embodiment includes a soil scattering part at the rear end of the agricultural machine and including a scattering part frame and a scattering unit provided on a lower end side of the scattering part frame and scattering soil on a floor, a mulching film laying part including a laying part frame connected to a rear end side of the soil scattering part and a mulching film holding part having a mulching film wound around the mulching film holding part and spreading the mulching film on the floor, an oscillating plate above the mulching film holding part and guiding the scattered soil to be transported to a rear side and laid on an upper surface of the mulching film, and a soil oscillating part including oscillator for oscillating the oscillating plate to prevent formation of a soil wall on the oscillating plate.
