Description

Technical Field

[0001] This invention relates to the field of water chestnut harvesting in paddy fields, and more particularly to a self-propelled water chestnut harvester for paddy fields. Background Technology

[0002] Water chestnut, also known as horse chestnut, is the bulbous tuber at the tip of the underground stolon of the water chestnut plant (Cyperus rotundus), a member of the Cyperaceae family. It has slender, creeping rhizomes from which tubers grow. Commonly called water chestnut, it thrives in shallow water and requires less nitrogen and more phosphorus fertilizer. Sufficient sunlight is necessary throughout its growing season. Patent CN221381801U provides an integrated machine for collecting and removing impurities from water chestnuts in paddy fields. It includes a base, with a cleaning assembly mounted on top of the base. The cleaning assembly includes a mounting frame fixedly connected to the top of the base, and a limit block mounted on top of the mounting frame. Two first motors have keyways connecting to second gears. This device provides an integrated machine for collecting and removing impurities from water chestnuts in paddy fields. The cleaning assembly includes a collection box. After the water chestnuts are fed into the collection box, eight rotating blocks are rotatably connected to support rods on their outer walls. The collection box is rotatably connected to the outer walls of the eight support rods on opposite sides. A sieve plate is located at the bottom of the collection box. Two rotating blocks have first gears mounted on their outer walls, causing the two first motors to drive the collection box to move back and forth inside the mounting frame. The sieve plate at the bottom of the collection box removes impurities from the surface of the water chestnuts during the shaking process, greatly improving the cleaning efficiency of the device. When the device described above is used, it moves along the vehicle body and uses a shovel to scoop up the water chestnuts from the soil. Then, it is transported by a transmission mechanism to a cleaning component for centralized cleaning. In this method, the shovel moves with the vehicle body, and a large amount of soil needs to be scooped in along with the water chestnuts. During the scooping process, a large amount of soil and water chestnuts are discharged together into the transmission component by pushing the scooped soil, and then enter the cleaning mechanism. In this method, a large amount of soil can easily get into the cleaning mechanism, resulting in high cleaning difficulty. It is not possible to improve the water chestnut scooping structure to remove some soil during scooping and clean some soil during the transmission process, and finally clean the water chestnuts to avoid a large amount of soil mixing in and affecting the cleaning difficulty. Therefore, we propose a self-propelled water chestnut harvester for paddy fields. Summary of the Invention

[0003] Purpose of the Invention: The purpose of this invention is to provide a self-propelled water chestnut harvester for paddy fields. By improving the water chestnut shovel structure, it can achieve preliminary separation of soil and water chestnuts at the initial stage of shoveling, effectively removing some of the attached and mixed soil. This solves the problem of excessive subsequent cleaning burden caused by existing devices collecting a large amount of soil and water chestnuts together during shoveling. Another purpose of this invention is to provide a self-propelled water chestnut harvester for paddy fields with multi-stage cleaning function. An intermediate cleaning stage is set in the transportation process of water chestnuts from shoveling to final cleaning, which performs secondary soil cleaning on the water chestnuts after preliminary impurity removal, further reducing the amount of soil entering the final cleaning mechanism, reducing the cleaning difficulty, and improving the overall harvesting and cleaning efficiency, ensuring the cleanliness of the harvested water chestnuts, and meeting actual production needs.

[0007] Furthermore, the transmission mechanism includes two shafts, each located to the left of one of the two shaft plates. The bottom of each shaft is fixedly connected to the upper surface of the side plate. A concave transmission net is rotatably connected between the two shafts via a rotating shaft. The right side of the concave transmission net is in contact with the outer wall of the cylinder. A transmission seat is located below the concave transmission net and inside the notch. The lower surface of the transmission seat is fixedly connected to the upper surface of the self-propelled vehicle. A driven roller is rotatably connected to the inner right side of the transmission seat via a rotating shaft. The front end and rear end of the central shaft of the driven roller extend to the front and rear surfaces of the transmission seat, respectively, and are fixedly connected to connecting pieces. Traction plates are rotatably connected to the upper sides of the opposite sides of the two connecting pieces via rotating shafts. The upper sides of the opposite sides of the two traction plates are rotatably connected to the left side of the front surface and the left side of the rear surface of the concave transmission net via rotating shafts.

[0008] Furthermore, an active roller is rotatably connected to the inner left side of the concave transmission network via a rotating shaft. The outer side wall of the active roller and the outer side wall of the driven roller are connected to a transmission belt. A second motor is fixedly connected to the front surface of the transmission base. The rear end of the output shaft of the second motor is fixedly connected to the front end of the central shaft of the active roller.

[0009] Furthermore, two mounting strips are fixedly connected to the left side of the upper surface of the transmission base, and a drain cylinder is fixedly connected between the two mounting strips.

[0010] Furthermore, the cleaning mechanism includes a water tank, the bottom of which is fixedly connected to the left side of the upper surface of the self-propelled vehicle. A water pump is fixedly connected to the upper surface of the water tank, the input end of which extends into the interior of the water tank, and the output end of which is fixedly connected to a diversion chamber one. A hose one is fixedly connected between the upper right side of the diversion chamber one and the drain cylinder, and a diversion chamber two is fixedly connected to the lower right side of the diversion chamber one.

[0011] Furthermore, a spray pipe is fixedly connected to the bottom end of the second hose, and the left end of the spray pipe is rotatably connected to the right side of the water tank via a rotating shaft.

The motor is fixedly connected to the opposite side of the bearing seats.

[0013] Beneficial effects: The device, through the cooperation of the collection mechanism, the transmission mechanism and the cleaning mechanism, constructs a three-level cleaning system of "preliminary impurity removal - secondary rinsing - final spraying". The mesh structure of the collection net shovel can expose some soil when shoveling horseshoes, thus completing the preliminary impurity removal. During the transmission process, the reciprocating swing of the concave conveyor further shakes off the attached soil, and the water spray from the drainage pipe achieves a secondary rinsing; the high-pressure spraying of the cleaning mechanism's spray pipe, combined with the reciprocating movement of the screen, performs a comprehensive final cleaning of the water chestnuts. The multi-stage collaboration greatly improves the cleanliness of the water chestnuts after harvesting and reduces subsequent manual cleaning costs. Ensuring cleanliness of the conveyor belt and self-propelled vehicle surfaces reduces maintenance difficulty: In the conveying mechanism, dirt shaken off by the concave conveyor net and sludge generated from conveyor belt washing are directly discharged through the concave openings of the self-propelled vehicle, preventing dirt from accumulating and clumping on the conveyor belt surface; wastewater and impurities from the cleaning mechanism fall into the grooves through the screen and are discharged, leaving no residue on the self-propelled vehicle surface. This directional waste removal design effectively prevents dirt and sludge from adhering to the conveyor belt and self-propelled vehicle surface, reduces component wear, lowers the frequency and difficulty of equipment cleaning and maintenance, and extends the service life of the equipment; The harvesting mechanism uses a motor to link rotary tillage and harvesting actions. After the rotary tillage wheel loosens the soil, the harvesting net shovel cycles to complete the "shovel-discharge" action, reducing the resistance of the water chestnuts and improving harvesting efficiency. The concave conveyor net of the transmission mechanism connects smoothly with the conveyor belt, preventing water chestnuts from falling during transmission. At the same time, cleaning is completed simultaneously during transmission, eliminating the need for a separate cleaning process and shortening the operation flow. The spray pipe swinging and screen movement of the cleaning mechanism work together to expand the cleaning range while ensuring cleaning uniformity, thus improving the overall efficiency of harvesting and cleaning, and adapting to the production needs of large-scale water chestnut harvesting in paddy fields.

[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example like Figure 1 and Figure 2 As shown, a self-propelled horseshoe paddy field harvester is provided, including a self-propelled vehicle 1; A notch 5 is provided on the right side of the self-propelled vehicle 1, and a groove 6 is provided on the upper surface of the self-propelled vehicle 1. The self-propelled vehicle 1 can move automatically by driving, and the notch 5 is used to discharge the soil shaken off by the concave transmission network 302 and the sludge washed by water during the transmission process of the conveyor belt 308.

[0018] like Figure 3 and Figure 4 As shown, a data collection mechanism 2 is located on the right side of the self-propelled vehicle 1; The collection mechanism 2 includes two side plates 201. The left side of the side plate 201 is fixedly connected to the right side of the self-propelled vehicle 1. The two side plates 201 are connected to a rotary tiller 202 on the opposite right side by a rotating shaft. The front end and rear end of the central shaft of the rotary tiller 202 pass through to the opposite sides of the two side plates 201 and are fixedly connected to a sprocket 203. A shaft plate 204 is fixedly connected to the left side of the upper surface of the side plate 201. A cylinder 205 is rotatably connected between the two opposing shaft plates 204 via a rotating shaft. A collection net shovel 206 is fixedly connected to the outer wall of the cylinder 205. A gear 207 is fixedly connected to the front end and rear end of the central shaft of the cylinder 205 on the opposite sides of the two shaft plates 204. Two incomplete gears 208 are rotatably connected to the upper sides of the opposite sides of the two shaft plates 204 via rotating shafts. The outer side wall of the incomplete gear 208 meshes with the outer side wall of gear one 207. Sprockets two 209 are fixedly connected to the opposite sides of the two incomplete gears 208. The outer side wall of sprocket one 203 and the outer side wall of sprocket two 209 on the same side are connected to the chain belt 210 for transmission. A torsion spring 213 is fixedly connected between gear 207 and shaft plate 204; L-shaped brackets 211 are fixedly connected to the left side of the opposite side of the two side plates 201. Motor 1 212 is fixedly connected to the inner side of the L-shaped bracket 211. The output shafts of the two motors 1 212 are fixedly connected to the center of the opposite side of the two sprockets 209 respectively. Start the self-propelled vehicle 1 to move along the paddy field operation path, and at the same time start the motor 212 on the two L-shaped brackets 211. The output shaft of the motor 212 drives the sprocket 209 to rotate. On the one hand, the sprocket 209 drives the sprocket 203 on the same side to rotate through the chain belt 210, which in turn drives the rotary tiller 202 between the two side plates 201 to rotate. The rotary tiller 202 loosens the paddy field soil, which facilitates the subsequent collection of water chestnuts by the net shovel 206. On the other hand, sprocket 209 drives the coaxial incomplete gear 208 to rotate. When the incomplete gear 208 meshes with gear 207, it pushes gear 207 to rotate around the shaft between the shaft plates 204, thereby driving the cylinder 205 and the outer collection net shovel 206 to flip, so that the collection net shovel 206 can be inserted into the loosened soil to shovel out the hoof and some soil. At this time, the torsion spring 213 between gear 207 and shaft plate 204 is twisted and stores power. When the incomplete gear 208 disengages from gear 207, the torsion spring 213 releases its elastic force, causing gear 207 to rotate in the opposite direction. This causes the cylinder 205 and the collecting shovel 206 to flip upwards and reset. During the flipping process, the mesh structure of the collecting shovel 206 allows some soil to leak out, achieving initial separation of the horseshoe from the soil and completing one collection action. The motor 212 continues to run, causing the collecting shovel 206 to cycle through the "downward shovel-upward discharge" action, conveying the horseshoe after initial impurity removal to the concave transmission net 302 on the left.

[0019] like Figure 5 and Figure 6 As shown, a transmission mechanism 3 is provided on the right side of the upper surface of the self-propelled vehicle 1; The transmission mechanism 3 includes two shafts 301, each located to the left of one of the two shaft plates 204. The bottom of each shaft 301 is fixedly connected to the upper surface of the side plate 201. A concave transmission net 302 is rotatably connected between the two shafts 301 via a rotating shaft. The right side of the concave transmission net 302 is in contact with the outer wall of the cylinder 205. A transmission seat 303 is located below the concave transmission net 302 and inside the notch 5. The lower surface of the transmission seat 303 is connected to the self-propelled... The upper surface of the vehicle 1 is fixedly connected to the driven roller 304 rotatably connected to the inside right side of the transmission seat 303 via a rotating shaft. The front end and rear end of the central shaft of the driven roller 304 pass through to the front and rear surfaces of the transmission seat 303 respectively and are fixedly connected to the connecting piece 305. The upper sides of the opposite sides of the two connecting pieces 305 are rotatably connected to the traction plate 306 via a rotating shaft. The upper sides of the opposite sides of the two traction plates 306 are rotatably connected to the left side of the front surface and the left side of the rear surface of the concave transmission net 302 via a rotating shaft. Inside the concave transmission network 302, on the left side, a drive roller 307 is rotatably connected via a rotating shaft. The outer side wall of the drive roller 307 and the outer side wall of the driven roller 304 are connected to a transmission belt 308. The front surface of the transmission seat 303 is fixedly connected to a second motor 311. The rear end of the output shaft of the second motor 311 is fixedly connected to the front end of the central shaft of the drive roller 307. Two mounting strips 309 are fixedly connected to the left side of the upper surface of the transmission base 303, and a drain cylinder 310 is fixedly connected between the two mounting strips 309. The motor 311 on the front surface of the transmission seat 303 is started. The output shaft of the motor 311 drives the active roller 307 to rotate. The active roller 307 drives the driven roller 304 to rotate synchronously through the transmission belt 308. When the driven roller 304 rotates, it drives the connecting pieces 305 at both ends to make circular motion. The connecting pieces 305 pull the left part of the concave transmission net 302 to swing up and down around the shaft between the shaft strips 301 through the traction plate 306. When the collection shovel 206 of the collection mechanism 2 places the horseshoes that have been initially cleaned onto the concave transmission net 302, the concave structure of the concave transmission net 302 can prevent the horseshoes from falling off. Its up-and-down swinging motion can further shake off the soil attached to the horseshoes. The shaken soil falls through the mesh of the concave transmission net 302 and is discharged into the paddy field through the notch 5 of the self-propelled vehicle 1. Meanwhile, driven by the active roller 307 and the driven roller 304, the conveyor belt 308 continuously conveys to the left, receiving and transporting the horseshoes on the concave conveyor net 302 to the left. During this process, the drain pipe 310 on the mounting strip 309 can be connected to the water source of the cleaning mechanism 4 to spray clean water onto the horseshoes on the conveyor belt 308, washing and removing impurities from the surface of the horseshoes and the conveyor belt 308. The sludge generated during washing is also discharged through the notch 5, achieving secondary cleaning during the horseshoe conveying process.

[0020] like Figure 7 and Figure 8 As shown, a cleaning mechanism 4 is provided on the left side of the upper surface of the self-propelled vehicle 1; The cleaning mechanism 4 includes a water tank 401. The bottom of the water tank 401 is fixedly connected to the left side of the upper surface of the self-propelled vehicle 1. A water pump 402 is fixedly connected to the upper surface of the water tank 401. The input end of the water pump 402 extends into the interior of the water tank 401. The output end of the water pump 402 is fixedly connected to a first diversion chamber 403. A first hose 404 is fixedly connected between the upper right side of the first diversion chamber 403 and the drain cylinder 310. A second diversion chamber 405 is fixedly connected to the lower right side of the first diversion chamber 403. Multiple second hoses 406 are fixedly connected to the outside of the second diversion chamber 405. The bottom end of the second hose 406 is fixedly connected to the spray pipe 407. The left end of the spray pipe 407 is rotatably connected to the right side of the water tank 401 through a rotating shaft. The outer wall of the spray pipe 407 is fixedly connected to the gear 408. The lower part of the outer wall of the multiple gears 408 is meshed with a rack 409. The lower surface of the rack 409 is fixedly connected to two support frames 410. The bottom of the two support frames 410 is located inside the groove 6 and is fixedly connected to a screen 411. Two bearing seats 412 are fixedly connected to the right side of the water tank 401 and to the left of the screen 411. A reciprocating screw 413 is rotatably connected between the two bearing seats 412 via a rotating shaft. Limiting strips 414 are fixedly connected to the opposite sides of the two bearing seats 412 and to the outer side of the reciprocating screw 413. A limiting sleeve 415 is fixedly connected to the left side of the screen 411 and to the outside of the limiting strips 414. A screw sleeve 416 is threaded to the outer side of the reciprocating screw 413. The right side of the screw sleeve 416 is fixedly connected to the left side of the screen 411. A motor 417 is fixedly connected to the front end of the reciprocating screw 413. The motor 417 is fixedly connected to the opposite side of the bearing seats 412. First, sufficient clean water is injected into the water tank 401. When the conveyor belt 308 of the transmission mechanism 3 transports the cleaned hoofs to the screen 411, the water pump 402 on the water tank 401 and the motor 417 on the shaft seat 412 are started. The water pump 402 draws the clean water in the water tank 401 to the diversion chamber 403. A portion of the clean water is transported through the hose 404 to the drain cylinder 310 of the transmission mechanism 3 to provide water for rinsing the hoofs during the transmission process. Another portion of clean water flows into the second distribution chamber 405 through the first distribution chamber 403, and then is distributed to each spray pipe 407 through multiple hoses 406. The spray pipes 407 spray the water chestnuts on the screen 411 under high pressure to achieve the final cleaning of the water chestnuts. At the same time, the motor 417 drives the reciprocating screw 413 to rotate around the shaft between the shaft seat 412. The reciprocating screw 413 drives the screen 411 to move back and forth through the screw sleeve 416. When the screen 411 moves, it drives the rack 409 to move synchronously through the support frame 410. The rack 409 drives multiple gears 408 that mesh with it to rotate alternately in the forward and reverse directions, thereby driving the spray pipe 407 to swing left and right around the shaft on the right side of the water tank 401, expanding the spray range and ensuring that all horseshoes can be thoroughly washed. The wastewater and a small amount of impurities generated during rinsing fall through the mesh of the screen 411 into the groove 6 of the self-propelled vehicle 1 and are discharged. The cooperation of the limiting strip 414 and the limiting sleeve 415 can ensure the stability of the screen 411 during movement. Finally, the cleaned horseshoes are left on the screen 411, completing the entire harvesting and cleaning process.
