DETAILED DESCRIPTION OF THE EMBODIMENTS

(6) The structure, functionality, and processing of the current invention are further described below with reference to the accompanying drawings and the concrete implementation examples. However, the protective range of this present invention includes but not limited to that.

(7) The high-speed transplanting mechanism having a laterally openable/closable duckbill according to the present invention includes the duckbill soil penetration angle adjusting arm 5. By adjusting the reverse-threaded adjusting screw rod, the duckbill transplanter can be tilted in a direction opposite to a driving direction of the transplanting machine. The backward tilting pot seedlings which are planted in a moment can be supported and pushed upright by the inertia thereof and the action of the rolling wheel turns the soil. That is, the backward tilting pot seedlings can be supported and pushed upright by the forward inertia thereof, overturning the conventional notion that seedling delivery and transplanting must be stationary; it can solve the problem of slow planting speed, low upright degree, and low planting quality, and increasing the quality and efficiency of transplanting. A transplanting mechanism having a laterally openable/closable duckbill suitable for a high-speed transplanter is provided in the present invention, its transplanting speed can be more than 60 pot seedlings per minute.

(8) FIG. 1 is a schematic structural view of the high-speed transplanting mechanism having a laterally openable/closable duckbill in this present invention. This mechanism includes a power input portion, a driving shaft 2, a rocker 3, a connecting rod 4, a transplanting power arm 6, a duckbill soil penetration angle adjusting arm 5, a duckbill transplanting portion 9 and mounting base of the transplanting device 10. The mounting base of the transplanting device is provided with a power arm support shaft 101 and an adjustable arm support shaft 102. The end of the driving shaft 2 is connected to the power input portion 1, the other end of the driving shaft 2 is fixed on the end of the rocker 3, and the other end of the rocker 3 is hinged with the middle of the transplanting power arm 6. The end of the transplanting power arm 6 is hinged with the duckbill transplanting portion 9, and the other end of the transplanting power arm 6 is hinged with the power arm support shaft 101 of the mounting base of the transplanting device 10. The pot seedling upright keeping unit is installed on the transplanter.

(9) FIG. 2 is a schematic structural view of the duckbill soil penetration angle adjusting arm 5. This duckbill soil penetration angle adjusting arm has a rear arm 52 and a front arm 54 with one end each thereof connected by means of a reverse-threaded adjusting screw rod 51, and other ends thereof hingedly connected to an adjusting arm support shaft (102) and the duckbill transplanting portion (9) respectively, the end of the rear arm 52 is provided with a left-handed threads hole 521, and the other end of the rear arm 52 is hinged with the adjustable arm support shaft 102; the end of the front arm 54 is provided with a right-handed threads hole 541, and the other end of the front arm 54 is hinged with the duckbill transplanting portion 9. The reverse-threaded adjusting screw rod 51 is connected by threaded holes in the rear arm 52 and in the front arm 54 respectively. The rear arm rotating sleeve 523 is on one end of the rear arm 52, and the rear arm rotating sleeve 523 hinged to the adjustable arm supports shaft 102. The front arm rotating sleeve 543 is on one end of the front arm 54, and the front arm rotating 543 hinged to the duckbill transplanting portion 9. A length of the reverse-threaded adjusting screw rod (51) enables the duckbill to tilt in a direction opposite to a driving direction of a transplanting machine, and a vertical central straight line of the duckbill makes an angle with the ground capable of being adjusted between 65-85. Adjust the reverse-threaded adjusting screw rod 51 allows the duckbill soil penetration angle adjusting arm 5 to extend or shorten. The duckbill soil penetration angle increases when the duckbill soil penetration angle adjusting arm 5 elongations is adjusted. Too large duckbill soil penetration angle is not conducive to high-speed transplanting and the pot seedlings upright. The effect is better when the duckbill soil penetration between 75-85. In addition, in order to make the duckbill soil penetration angle easier to be observed or adjusted, the angle scale plate is set on one side of the duckbill transplanting portion 9.

(10) The power input portion 1 can be driven by an electric motor or a fuel engine. The prime power of the fuel engine or the electric motor is inputted by the power input portion 1, then the driving shaft 2 turns the rocker 3, and drives the transplanting power arm 6 through the connecting rod 4, in turn, drives the duckbill transplanting portion 9 moves up and down. According to the information obtained from the rotary speed of duckbill transplanting portion 9 matching with the land wheel speed of the transplanter, the duckbill opens and closes by the duckbill opening and closing control part 7 to complete the transplanting of the pot seedling, and the transplanting of the pot seedling is consistent with its agronomic requirements. The lateral adjusting rod 8 is used for the installation and adjustment of the duckbill transplanting portion 9.

(11) In order to prevent the effect of vibration on the transplanting quality caused by the change of the length of the duckbill soil penetration angle adjusting arm 5 during the operation of the transplanting, the two ends of the reverse-threaded adjusting screw rod 51 are respectively equipped with fastening nuts to prevent the loosening of the reverse-threaded adjusting screw rod 51.

(12) In this embodiment, in order to improve the strength of the duckbill soil penetration angle adjusting arm 5 and to facilitate the adjustment of its length, an extension part is set at one end with screw holes in the rear arm 52 and the front arm 54 respectively, and two extension parts can be connected by sliding fit. Specifically, there are multiple ways to assemble two extension parts, as shown in FIG. 2, FIG. 3, FIG. 4, the sliding adjusting groove 522 is provided at one end of the rear arm 52 connected to the front arm 54, the guide pin shaft 53 is provided at one end of the front arm 54 connected to the rear arm 52, the guide pin shaft 53 is installed in the guide pin shaft hole 542, and the guide pin shaft 53 interference fits with the pin shaft hole 542. The guide pin shaft 53 is inserted into the slide adjustment groove 522, and the guide pin shaft 53 can slide in the slide adjustment groove 522 to play a guiding role.

(13) In addition, where the extension part of the front arm 54 has a counterbore that corresponds to the sectional shape of the extension part of the rear arm 52, the extension part of the rear arm 52 is inserted into the counterbore, and the two sides of the counterbore are the sliding guide fit. There are some ball bearings between the extending part of the rear arm 52 and both sides of the counter bore, it can reduce the friction between the extension part of the rear arm 52 and the counterbore when adjusting the lateral adjusting rod 8, and it can easily adjust the length of the duckbill soil penetration angle adjusting arm 5.
