A crusher includes a blade assembly and a drive assembly. The blade assembly includes a first blade and a second blade. The drive assembly is respectively connected with the first blade and the second blade, and is configured to drive the first blade and the second blade to rotate. The first blade is configured to disperse and perform primary cutting of the materials. The second blade is configured to perform secondary cutting of the materials. The first blade makes the materials fully disperse, so that the second blade can fully cut the materials. In addition, the first blade initially cuts the materials, so that the formed fragments can achieve a better fertilization effect.

An adapter method and system includes a first side deflector, a second side deflector, and a top deflector coupled to the first side deflector and the second side deflector. The system may further include an internal deflector coupled to the first, second, and top deflectors. A first leg is coupled to the first side deflector and a second leg is coupled to the second side deflector. The legs are adjustable between a first position and a second position. The first, second, and top deflector define an entrance region for channeling wood-based debris into the chute of a woodchipper. Each side deflector may include a coupling mechanism for attaching to a woodchipper. Each coupling mechanism has an aperture. Each leg may telescope within a respective side deflector.

A system for prioritizing trim requests can include an image processor that identifies a location associated with a customer trim request that includes an image of vegetation and industrial equipment and marks the vegetation and the industrial equipment visible in the image associated with the customer trim request. The system can also include a vegetation maintenance analyzer that searches for a match between the identified location associated with the customer trim request with a location associated with one of a past executed service ticket and a pending service ticket. The maintenance analyzer generates a maintenance profile for the customer trim request based on the results of the search and data in the customer trim request. The system can further include a priority engine that assigns priority to the customer trim request based on the maintenance profile for the customer trim request.

The present disclosure relates to methods for the cultivation of perennial artichoke plants. Specifically, the present disclosure relates to methods of cultivating artichoke plants to increase the uniformity and yield of marketable products (e.g. edible mature buds), and to accurately program and condense the harvest interval of artichoke plants grown as perennials in a planting field in order to reduce production and harvesting costs.

The first embodiment of the tool for girdling the trunk of a tree includes an elongated and horizontally disposed handle having first and second ends. The tool also includes a horizontally disposed cutting blade support having a first elongated arm portion and a curved arm portion. The first elongated arm portion is pivotally connected to the handle intermediate the lengths thereof. A linkage also pivotally connects the second end of the handle to the first end of the first elongated arm portion. A cutting blade carriage is selectively movably secured to the curved arm portion to compensate for various tree trunk diameters. A second embodiment of the tool includes an elongated handle which is adjustably secured to a cutting blade support which has a cutting blade secured thereto which is forced into engagement with the tree trunk by a spring arm.

The thorn extractor apparatus has a frame, a roller, a screen that surrounds the roller and a screen roller, and a removably attachable collection bin for receiving the thorny seeds. The roller and screen work together to pick up and convey the thorny seeds to the removably attachable collection bin to be discarded.

In a device that uses the tank from a conventional vacuum cleaner, the tank is under positive pressure. A cap fits over a tubular element inside the tank and closes the conventional air inlet. The cap has a peripheral wall that extends between a solid back and a front radial rim, and interior axial ribs. The lid is held by a latch that has an element that pivots with respect to the tank and the lid, and a clasp that has a bent arm. A tensioner pulls the bent arm. The tensioner has a threaded rod that extends from a handgrip though a hole in the pivoting element. A nut on the clasp receives a threaded end of the threaded rod, enabling the handgrip to be used to tighten the clasp. An outer wall of the latch is disposed outwardly of the threaded rod and the bent arm.

A seedling-cutting apparatus includes a pair of arms that is to nip a portion of a stem of a seedling for grafting and that can be opened and closed and a blade that is provided so as to be capable of reciprocating relative to the portion of the stem. At least one of the pair of arms includes a through hole or a cutout that penetrates a portion of the arms along a direction in which the blade reciprocates. At least a portion of the through hole or the cutout faces the portion of the stem and at least a portion of the blade moves through the through hole or the cutout.
