Description

Technical Field

[0001] This utility model relates to the technical field of hand-held rice transplanters, specifically a hand-held rice transplanter with an adjustable seedling storage trough. Background Technology

[0002] A rice transplanter is an agricultural machine that plants rice seedlings into paddy fields. During planting, a mechanical claw first removes several rice seedlings from a seedbed and plants them into the soil. To maintain a right angle between the seedbed and the ground, the front end of the claw must move in an elliptical curve. The movement is accomplished by a planetary mechanism using rotary or variable gears, while a forward engine drives these mechanical components. For movement on soil, the transplanter must have non-slip wheels and a floating design. If planting in clusters, seedlings are taken from specific seed boxes and planted mechanically.

[0003] Hand-held rice transplanters typically have a seedling storage device at the rear for easy transplanting. However, current technology generally uses welding to position the placement plate, making it non-adjustable. Errors during the loader's manufacturing or assembly process can lead to misalignment between the placement plate notch and the transplanting rod. Therefore, we propose a hand-held rice transplanter with an adjustable seedling storage trough to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a hand-held rice transplanter with an adjustable seedling storage trough to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hand-held rice transplanter with an adjustable seedling storage trough, comprising a rice transplanter body, wherein a placement device is provided at the rear of the rice transplanter body, and the placement device includes an adjustment part;

[0006] The adjustment part includes a placement plate, a connecting block, a screw, a fixing block, a connecting rod, a sleeve, a first screw, and a second screw. The fixing block is threaded onto the outer surface of the screw. The right end of the connecting block has a groove. The left end of the connecting rod extends into the interior of the connecting block and is hinged to the inner wall of the connecting block. The right end face of the connecting rod is fixedly connected to the left end face of the T-shaped slider. The sleeve is threaded onto the outer surfaces of the first screw and the second screw.

[0007] The placement device also includes a positioning part;

[0008] The positioning part includes a limiting block, a railing, a fixing plate, and a limiting rod. The fixing plate is slidably sleeved on the outer surface of the limiting rod. The right end face of the fixing plate and the right end face of the limiting block are both fixedly connected to the left end face of the placement plate.

[0009] A further improvement is that the adjustment part also includes a T-shaped slider, a connecting bolt, and a mounting base. The left end face of the fixing block is fixedly connected to the right end face of the placement plate. The outer surface of the bottom end of the screw is rotatably connected to the top surface of the connecting block through a bearing seat. By setting the screw, fixing block, and connecting block, and by rotating the screw, the relative position of the connecting block and the fixing block can be adjusted, thereby adjusting the placement height of the placement plate.

[0010] A further improvement is that a T-shaped groove is provided on the outer surface of the mounting base, and the mounting base is slidably sleeved on the outer surface of the T-shaped slider. By setting the T-shaped slider and the mounting base, it is convenient to install the plate.

[0011] A further improvement is that the bottom end of the first screw is hinged to the right end face of the placement plate, and the top end of the second screw is hinged to the left end face of the T-shaped slider. The threads on the outer surfaces of the first and second screws rotate in opposite directions. By setting up a sleeve, the first screw, and the second screw, the deflection angle of the placement plate can be adjusted by rotating the sleeve.

[0012] A further improvement is that the outer surface of the left end of the connecting bolt is threaded through the right end face of the mounting base and the right end face of the T-shaped slider and extends into the interior of the T-shaped slider. By setting the connecting bolt, it is convenient to install and disassemble the plate.

[0013] A further improvement is that the positioning part also includes a stop block and a spring. The outer surface of the stop block is fixedly connected to the outer surface of the railing. The top surface of the limiting block has a slot. The outer surface of the railing extends into the limiting block and is adapted to the inner wall of the slot. By setting the railing, it is convenient to support the seedlings.

[0014] A further improvement is that the top end of the spring is fixedly connected to the bottom surface of the fixed plate, and the bottom end of the spring is fixedly connected to the inner wall of the limiting rod. By setting the spring, the limiting seat and the limiting rod, the elastic force of the spring is used to position the railing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable hand-held rice transplanter with a seedling storage trough, by setting up a placement plate, connecting block, screw, fixing block, connecting rod, sleeve, first screw, and second screw, can change the distance between the fixing block and connecting block by rotating the screw, thereby changing the position of the placement plate and adjusting its vertical position. By rotating the sleeve, the overall length of the sleeve, first screw, and second screw can be changed, adjusting the tilt angle of the placement plate and the relative position of the placement plate and the main body of the rice transplanter, ensuring that the insertion rod corresponds to the notch of the placement plate. By setting up a mounting base, T-shaped slider, and connecting bolts, the T-shaped slider is spliced ​​with the mounting base, and the mounting base is connected to the T-shaped slider using the connecting bolts, facilitating the installation and disassembly of the placement plate. By setting up a stop block, railing, limiting block, spring, fixing plate, and limiting rod, the railing limits the seedlings, and the spring force causes the limiting rod to press and position the railing. The position of the railing can be adjusted left and right according to the different centers of gravity of the seedlings at different growth stages. Attached Figure Description
