Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, specifically a rice transplanter with a cleaning structure. Background Technology

[0002] A rice transplanter is an agricultural machine that plants rice seedlings into paddy fields. When planting, the mechanical claw first takes several rice seedlings from the seedbed and plants them into the soil in the field. In order to maintain a right angle between the seedbed and the ground, the front end of the mechanical claw must move in an elliptical motion curve. The motion is accomplished by a planetary mechanism with rotary or deformable gears. The forward engine can drive these mechanical actions at the same time. The rice transplanter must have non-slip wheels and a floating design to move on the soil. If the seedlings are to be planted in a row, the rice seedlings are taken out from a specific seedling box and then planted mechanically.

[0003] In existing technologies and rice transplanter operations, although mechanized equipment breaks up the soil and clears weeds in the paddy field, a large amount of clumps of soil and weeds still remain in the paddy field during actual transplanting. This increases wear and tear on the transplanter's planting section and causes blockages. Weeds also become entangled in the planting section. Furthermore, when inserting seedlings, the obstruction of contact between the seedling roots and soil clumps and weeds can easily damage the seedling roots and affect the survival rate. Therefore, we propose a rice transplanter with a cleaning structure to solve this defect of existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rice transplanter with a cleaning structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice transplanter with a cleaning structure, comprising:

[0006] The rice transplanter body has a telescopic support assembly detachably mounted on its head frame. The telescopic support assembly includes a pair of telescopic rods, the lower end of which is an extension end.

[0007] The mounting bracket assembly is located between the lower ends of the telescopic rods;

[0008] A drive and push component is connected between the telescopic support assembly and the mounting frame assembly, and cooperates to drive the mounting frame assembly to move;

[0009] A winding roller that rotates inside the mounting frame assembly, and the outer side of the winding roller is provided with a plurality of arc-shaped hooks that are circumferentially spaced and equidistant from the side;

[0010] Multiple elastic telescopic members are provided on the mounting frame assembly. Each elastic telescopic member is provided with a cutter. The cutter is located at the gap between the arc-shaped hooks and is in contact with the surface of the winding roller.

[0011] A drive assembly is mounted on the mounting frame assembly to drive the winding roller to rotate, and a telescopic rod synchronously extends and retracts to support the mounting frame assembly.

[0012] Using the above technical solution, during use, the telescopic support assembly is installed on the front frame of the rice transplanter. Then, in conjunction with the drive and push components, the mounting frame assembly is moved, causing the winding roller and the arc hook to move down into the paddy field simultaneously. The drive assembly is activated to drive the winding roller and the arc hook to rotate synchronously. As the rice transplanter moves, the arc hook, which is rotating deep into the paddy field, breaks up the clumps of soil. At the same time, the arc structure of the arc hook rotates to hook up and entangle the weeds in the paddy field. With the synchronous rotation of the winding roller and the arc hook, the elastic telescopic component keeps the cutter in contact with the winding roller to cut and crush the weeds entangled on the arc hook.

[0013] As a preferred embodiment of this utility model, the telescopic support assembly further includes a docking mounting plate and a connecting plate. The docking mounting plate is connected to the vehicle front frame, and the connecting plate is located at the lower end of the docking mounting plate. The lower end of the connecting plate is connected to the other end of the telescopic rod.

[0014] By adopting the above technical solution, the installation, fixation, and retraction of the telescopic support component are guaranteed.

[0015] As a preferred embodiment of this utility model, the mounting bracket assembly includes a movable connecting bracket, a pair of vertical support brackets, and a connecting horizontal bracket. The movable connecting bracket is connected between the lower ends of the telescopic rod, the vertical support brackets are respectively located on the front and rear sides of the lower end of the movable connecting bracket, and the connecting horizontal bracket is located between the vertical support brackets.

[0016] By adopting the above technical solution, the overall structure of the mounting bracket assembly improves the support and reinforcement effect.

[0017] As a preferred embodiment of this utility model, the winding roller rotates between the vertical support frames and is located below the connecting horizontal frame.

[0018] The above technical solution ensures the stability of the winding roller connection rotation.

[0019] As a preferred embodiment of this utility model, the driving and pushing component is a hydraulic push rod, which is detachably mounted on the upper end of the connecting plate, and its push rod is connected to the movable connecting frame.

[0020] Using the above technical solution, the hydraulic push rod works to move the movable connecting frame.

[0021] As a preferred technical solution of this utility model, the elastic telescopic component includes a plurality of hollow limiting cylinders and stainless steel springs. The hollow limiting cylinders are evenly distributed at the lower end of the connecting transverse frame, and the stainless steel springs are disposed inside the hollow limiting cylinders, with their other ends connected to the cutter.

[0022] By adopting the above technical solution, the elastic expansion and contraction of the elastic expansion component can be achieved in a linear manner.

[0023] As a preferred technical solution of this utility model, the drive assembly includes a dual-axis output motor, a pair of shafts, transmission gears and a transmission chain. The dual-axis output motor is located at the lower center of the movable connecting frame, and the shafts are connected to the two output ends of the dual-axis output motor and are connected to the vertical support frame for rotation.

[0024] The shaft is coaxially provided with transmission gears at both ends of the winding roller, and transmission chains are respectively meshed and sleeved between the transmission gears on the left and right sides.

[0025] By adopting the above technical solution, the drive component is made to drive the winding roller to rotate.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0027] This rice transplanter with a cleaning structure is mounted on the front frame of the transplanter body via a telescopic support assembly. A drive mechanism then moves the mounting frame assembly, causing the winding roller and arc hook to simultaneously descend into the paddy field. The drive assembly then rotates the winding roller and arc hook synchronously. As the transplanter moves, the rotating arc hook breaks up clumps of soil, while its arc shape hooks up and entangles weeds. The elastic telescopic component keeps the cutter in contact with the winding roller, cutting and pulverizing the weeds entangled on the arc hook. This facilitates the removal of clumps of soil and weeds, allowing the transplanter to proceed with subsequent transplanting. It also prevents wear and blockage of the transplanter's planting section during planting, avoiding the problem of weeds getting tangled in the planting section and hindering seedling root contact with soil and weeds, which can damage seedling roots and affect survival rates.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-3 This embodiment of a rice transplanter with a cleaning structure includes: a rice transplanter body 1, on which a telescopic support assembly 2 is detachably mounted. The telescopic support assembly 2 includes a pair of telescopic rods 203, the lower end of which is an extension end. The telescopic support assembly 2 includes a docking mounting plate 201, a connecting plate 202, and a pair of telescopic rods 203. The docking mounting plate 201 is fixedly connected to the head frame by bolts or other detachable connection methods. The connecting plate 202 is installed and fixed at the lower end of the docking mounting plate 201. The upper end of the telescopic rod 203 is connected and fixed to the connecting plate 202, and the lower end is an extension end used to support the mounting frame assembly 4.

[0035] The mounting frame assembly 4 is located between the lower ends of the telescopic rods 203. The mounting frame assembly 4 includes a movable connecting frame 401, a pair of vertical support frames 402, and a connecting transverse frame 403. The movable connecting frame 401 is connected and fixed between the lower ends of the telescopic rods 203. The vertical support frames 402 are respectively installed and fixed on the front and rear sides of the lower end of the movable connecting frame 401. The connecting transverse frame 403 is installed and fixed between the vertical support frames 402, forming a stable frame structure for supporting the winding roller 5 and other components.

[0036] The winding roller 5 is installed in a circular rotation between the vertical support frames 402 and located below the connecting horizontal frame 403. The outer surface of the winding roller 5 is integrally formed and fixed with multiple arc-shaped hooks 6 that are arranged in a ring and distributed horizontally at equal distances. The design of the arc-shaped hooks 6 enables it to effectively break up the clumps of soil in the paddy field and hook up weeds during rotation.

[0037] Please see Figure 4 Multiple elastic telescopic components 7 are mounted on the mounting frame assembly 4. Each elastic telescopic component 7 is equipped with a cutter 8, which is located in the gap between the arc hooks 6 and contacts the surface of the winding roller 5. The elastic telescopic component 7 includes multiple hollow limiting cylinders 701 that are installed and fixed at equal intervals at the lower end of the connecting transverse frame 403. A stainless steel spring 702 is installed and fixed inside the hollow limiting cylinder 701. The upper end of the stainless steel spring 702 is fixedly connected to the inner wall of the hollow limiting cylinder 701, and the other end is fixedly connected to the cutter 8. The cutter 8 is located in the gap between the arc hooks 6 and is always in contact with the surface of the winding roller 5. This design allows the cutter 8 to always adhere to the surface of the winding roller 5 under the action of the elastic telescopic component 7, so as to cut and crush the weeds wrapped on the arc hooks 6.

[0038] The drive and push component is connected between the telescopic support assembly 2 and the mounting frame assembly 4, and works to move the mounting frame assembly 4. The drive and push component adopts a hydraulic push rod 3, which is detachably installed on the upper surface of the connecting plate 202 by bolts or other connection methods. The push rod end of the hydraulic push rod 3 is connected and fixed to the upper surface of the movable connecting frame 401. Through the telescopic movement of the hydraulic push rod 3, the mounting frame assembly 4 can be pushed up and down, thereby adjusting the position of the winding roller 5 and the arc hook 6 in the rice paddy.

[0039] The drive assembly, mounted on the mounting frame assembly 4, drives the winding roller 5 to rotate. The drive assembly includes a dual-axis output motor 9, a pair of shafts 10, transmission gears 11, and transmission chains 12. The dual-axis output motor 9 is bolted to the center of the lower surface of the movable connecting frame 401. The shafts 10 are connected and fixed to the output ends of the dual-axis output motor 9 on both sides and connected to the vertical support frame 402 to achieve rotation. The transmission gears 11 are mounted and fixed coaxially with the outer ends of the shafts 10 and the two outer ends of the winding roller 5. The transmission chains 12 are respectively meshed and sleeved between the outer ends of the transmission gears 11 on the left and right sides. Driven by the dual-axis output motor 9, the transmission gears 11 and the transmission chains 12 drive the winding roller 5 to rotate, thereby realizing the rotation of the arc hook 6.

[0040] Work process:

[0041] Before transplanting, the mounting frame assembly 4 is lowered by the hydraulic push rod 3, allowing the winding roller 5 and the arc hook 6 to penetrate deep into the soil of the paddy field. The dual-shaft output motor 9 is started, driving the winding roller 5 and the arc hook 6 to rotate. As the transplanter moves, the arc hook 6 rotates in the paddy field, breaking up clumps of soil and hooking weeds onto the winding roller 5. At the same time, the cutter 8 on the elastic telescopic component 7, under the action of the stainless steel spring 702, always adheres to the surface of the winding roller 5, cutting and crushing the weeds wrapped around the arc hook 6. In this way, the cleaned paddy field can effectively reduce the wear and blockage of the transplanter's transplanting part, while avoiding weeds from getting tangled on the transplanting part, thus improving the survival rate of seedlings.
