DETAILED DESCRIPTION

[0024] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0025] Example 1

[0026] A transplanting punch with adjustable plant spacing, such as Figure 1-4 As shown, it includes a frame 1, a material transfer barrel 10 movably mounted on the frame 1, and a drill rod 32; a driving assembly for driving the material transfer barrel 10 to move up and down is installed on the frame 1; a drill bit is installed at the lower end of the drill rod 32; the drill rod 32 and the material transfer barrel 10 are connected by a telescopic rod 31 with a locking function.

[0027] In the above-mentioned transplanting punching machine with adjustable plant spacing, the drill rod 32 is connected to the transfer barrel 10 by a telescopic rod 31 with a locking function. The driving component drives the transfer barrel 10 to move up and down, which can drive the drill rod 32 to move up and down to achieve synchronous drilling and transplanting. When the plant spacing needs to be adjusted, just adjust the length of the telescopic rod 31. The present application has a simple structure, low production cost, and is convenient to assemble and debug. After purchasing, farmers can also adjust the plant spacing according to actual needs, and it is flexible to use. In this embodiment, the telescopic rod 31 with a locking function can be selected from several types of structures commonly available on the market. For example, a self-locking telescopic rod with a non-powered fastener can be used, including an upper rod, a lower rod and a fastener; a powered electric push rod and other structures can also be used. Those skilled in the art can freely choose according to actual needs.

[0028] Furthermore, the frame 1 is provided with a strip-shaped groove 33 to accommodate the movement of the drill rod 32. A movable guide sleeve 16 is removably fixed to the frame 1 and engages with the drill rod 32. A guide sleeve 14 is fixedly attached to the frame 1 and slidably engages with the transfer barrel 10. The movable guide sleeve 16 engages with the drill rod 32 to guide its vertical movement. The installation position of the movable guide sleeve 16 can be adjusted to suit the position of the drill rod 32. Both the guide sleeve 14 and the movable guide sleeve 16 serve as guides.

[0029] Furthermore, a storage plate 22 is fixedly connected to the frame 1 through a support rod 23. During operation, the seedlings to be transplanted are placed on the storage plate 22 for easy access by operators.

[0030] Furthermore, a screw sleeve 24 is fixed to the frame 1, and a thread is provided on the lower portion of the support rod 23 to cooperate with the screw sleeve 24. By adjusting the depth of the support rod 23 screwed into the screw sleeve 24, the installation height of the storage plate 22 is adjusted to adapt to the height of different operators.

[0031] Furthermore, the drive assembly includes a screw 8 rotatably mounted on the frame 1; a guide rod 13 is fixed to the frame 1; a nut block 9 threadedly connected to the screw 8 and a guide block 11 slidably connected to the guide rod 13 are fixed to the side walls of the feed barrel 10; a drive motor 20 is mounted on the frame 1; and a drive gear 19 is mounted on the output shafts of the screw 8 and the drive motor 20, which mesh with each other. The drive motor 20 drives the screw 8 through the drive gear 19, and the feed barrel 10 moves up and down under the combined action of the nut block 9, guide block 11, and guide rod 13.

[0032] Furthermore, limit rings 17 are removably mounted on the upper and lower portions of the guide rod 13. A limit switch 18 is fixedly attached to the limit rings 17. The limit switch 18 is connected to a drive motor 20, which controls the forward and reverse rotation of the drive motor 20. Adjusting the installation position of the limit rings 17 can adjust the depth of transplanting and drilling.

[0033] Furthermore, buffer plates 15 are provided on two opposite sides of the inner wall of the transfer barrel 10. The buffer plates 15 are made of a flexible material, one end of which is adhered to the inner wall of the transfer barrel 10. When impacted, the buffer plates 15 rotate around the connection with the transfer barrel 10 and may even deform, thereby cushioning the seedlings and preventing them from being damaged by a large impact force when they fall to the ground too quickly.

[0034] Furthermore, for ease of operation, a seat 21 is fixedly mounted on the frame 1 .

[0035] Further, a closable cone 25 is installed at the bottom of the feeding barrel 10. By controlling the opening and closing of the cone 25 to control the final delivery of the seedlings, the rhythm of manually placing the seedlings in the feeding barrel 10 can be relaxed, and it is not necessary to be so accurate.

[0036] Furthermore, the cone 25 is composed of two half-cones, and the upper ends of the two half-cones are hinged to the transfer cylinder 10; the contact edges of the two half-cones are provided with mutually engaging parts 5; a spring 6 is connected between the outer walls of the two half-cones; a rocker 29 is installed at the lower part of the frame 1; a cam 26 is rotatably installed at the lower part of the frame 1; the rotation of the cam 26 is driven by a unloading motor 27 connected to its rotating shaft; one end of the rocker 29 is hinged to the mounting frame at the lower part of the frame 1, and the other end is mounted on the cam 26 and is connected to a rope 30; the other end of the rope 30 is connected to the top of one of the half-cones; the cam 26 is arranged on the side of the half-cone to which the rope 30 is not connected. During use, the speed of the discharge motor 27 is adjusted in advance. The rotation of the discharge motor 27 drives the cam 26 to rotate, intermittently lifting the rocker 29 and intermittently tightening the rope 30. When the rope 30 is tightened, the right half-cone rotates, and the left half-cone rotates in the opposite direction under the action of the bite portion 5, thereby opening the cone 25. When the rope 30 is loosened, the two half-cones return to the closed state under the action of the spring 6.

[0037] Furthermore, a water tank 2 is mounted on the frame 1. An annular water tank 4 is fixed to the upper sidewall of the cone 25. A water pipe 3 connects the two annular tanks 4. Several nozzles are mounted at the bottom of the annular tank 4. A control valve is installed on the outlet pipe of the water tank 2. The opening and closing intervals of the control valve are adjusted in advance. Water, fertilizer, or liquid medicine in the water tank 2 flows through the water pipe 3 into the annular tank 4. The liquid is then sprayed onto the transplanted seedlings by the nozzles mounted on the annular tank 4, achieving precise application.

[0038] Example 2

[0039] A transplanting punch with adjustable plant spacing, such as Figure 5 As shown, compared with Example 1, only the drive assembly of the material transfer barrel 10 is changed. Specifically, the drive assembly includes an electric push rod 12 fixedly mounted on the frame 1; a guide rod 13 is fixed to the frame 1; and a push block 7 connected to one end of the electric push rod 12 and a guide block 11 slidably connected to the guide rod 13 are fixed to both sides of the side wall of the material transfer barrel 10.

[0040] The working principle of this utility model:

[0041] During operation, the entire device can be towed by a tractor, or a drive mechanism can be installed to drive the running wheels. A battery or generator is mounted on the frame 1 to provide power for all electrical appliances. During operation, the drive assembly is controlled to move the feed drum 10 up and down, driving the drill rod 32 up and down synchronously, thereby achieving simultaneous drilling and transplanting operations. Seedlings to be transplanted, placed on the storage plate 22, are placed into the feed drum 10. The seedlings are blocked by the buffer plate 15, slowing their descent and landing within the closed cone 25. By controlling the operating parameters of the discharge motor 27 and the drive assembly, when the feed drum 10 reaches its lowest point, the cam 26 rotates just enough to raise the rocker 29 to its highest point. The rope 30 is tightened, driving the right half-cone to rotate. The engaging portion 5 simultaneously drives the left half-cone to rotate in the opposite direction, causing the cone 25 to open and the seedlings to be transplanted within the feed drum 10 to fall into the holes.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
