Description

Technical Field

[0001] The invention relates to the field of film-covered rice transplanters, in particular to a rice film-covered rice transplanter. Background Art

[0002] Rice is a widely planted crop in my country with a history of thousands of years. With the advancement of science and technology, today's rice planting technology has also developed. The popularization of rice transplanters has replaced traditional manual planting with mechanical planting, greatly improving planting efficiency.

[0003] In the prior art, in the process of planting rice using a rice transplanter, a layer of mulch film can also be laid in the field to hinder the growth of weeds and play a role in keeping warm and moisturizing, which helps to increase the yield of rice.

[0004] In the prior art, it is possible to simultaneously lay ground film during the transplanting process, such as a rice film-covered transplanter with publication number CN114521374A.

[0005] However, the paddy fields where rice is grown are definitely different from dry land. The mulch in the paddy fields is fixed by pressing it into the mud at the bottom of the water. This fixation method relies on the viscosity of the mud at the bottom of the water. After laying, the mulch can easily float on the water surface due to the buoyancy of the water and cause the laying to fail. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a rice film mulching transplanter, which stores sludge in a storage box, drives a conveying shaft to rotate through a motor, transmits the sludge to a diversion box through a conduit, and finally allows the sludge to fall on the ground film through a discharge trough, thereby pressing the sludge on the ground film, increasing the fixing strength of the ground film, and preventing the ground film from floating on the water surface under the action of buoyancy, thereby effectively solving the problems in the background technology.

[0008] (II) Technical solution

[0009] To achieve the above object, the technical solution adopted by the present invention is: a rice film covering transplanter, comprising a flatbed vehicle, a rice transplanter assembly is installed at the rear end of the flatbed vehicle, so as to insert the rice seedlings into the paddy field, a film covering assembly for laying ground film is provided at the bottom of the flatbed vehicle, multiple ground films on the film covering assembly are rolled into a cylindrical shape, a turning mechanism is provided at both the front and rear ends of the flatbed vehicle, and a pressure mechanism is provided on the flatbed vehicle;

[0010] The pressure - applying mechanism includes a storage box fixedly arranged at the top of the flatbed truck. The storage box is filled with sludge inside. A shunt box is arranged at the bottom of the flatbed truck. Two conduits for transporting sludge are fixedly arranged at the top of the shunt box to introduce the sludge in the storage box into the shunt box. The top of the conduit penetrates through the flatbed truck and is fixedly connected to the bottom end of the storage box.

[0011] A bottom plate is installed at the bottom end of the shunt box. A plurality of discharge slots are opened on the bottom plate, and the sludge is discharged through the discharge slots.

[0013] A plurality of inclined blocks are fixedly arranged at the bottom end inside the storage box. The inclined blocks cause the sludge in the storage box to converge at the two conduits, reducing the sludge residue in the storage box.

[0014] Furthermore, two connecting shafts are arranged inside the storage box. The top ends of the connecting shafts extend to the top of the cover plate and are movably connected to the cover plate through bearings. The top ends of the connecting shafts are respectively fixedly connected to the output shafts of the two motors, so as to drive their rotation through the motors.

[0015] A conveying shaft is fixedly arranged at the bottom end of the connecting shaft. The upper half of the conveying shaft is located in the storage box, and the lower half of the two conveying shafts respectively extends into the two conduits. The sludge is input into the conduits by the rotation of the conveying shafts.

[0018] A plug rod is inserted into the central position of the plastic film wound into a cylindrical shape. The cylindrical plastic film thus rotates around the plug rod. The two ends of the plug rod respectively pass through the sleeve tubes on both sides and are connected to the sleeve tubes through bolts, so as to install and disassemble the plug rod and the plastic film.

[0019] The outer edge of any two adjacent plastic films overlaps by one centimeter, avoiding the influence of gaps on the laying effect. Each overlapping part corresponds to a row of seedlings. The seedlings are inserted into the overlapping part of two adjacent plastic films, reducing the resistance during rice transplanting.

[0020] Further, a connecting plate is provided on the top of the flatbed truck. Two springs and two sliding rods are fixedly provided at the bottom end of the connecting plate, and the two springs are arranged between the two sliding rods;

[0021] The bottom end of the sliding rod extends to the bottom of the flatbed truck and is fixedly connected to the top end of the fixing plate. The bottom end of the spring is connected to the front-side flipping mechanism. With the elastic force of the spring, the plastic film is in full contact with the soil at the bottom of the paddy field for laying.

[0022] Further, a leveling assembly is provided at the front end of the flatbed truck. The leveling assembly and the spring are installed on the same flipping mechanism. The leveling assembly includes a pressing plate which is horizontal with the ground and contacts the ground during use to scrape the soil in the paddy field flat. A V-shaped push plate is fixedly provided at the top end of the pressing plate to temporarily push the water to both sides by means of the thrust of the V-shaped push plate.

[0023] Further, two adjusting vertical rods are fixedly provided at the top end of the V-shaped push plate. A limiting piece is fixedly provided at the top end of the adjusting vertical rod. A sleeve is sleeved on the outer end of the adjusting vertical rod to adjust the height of the pressing plate accordingly. The sliding range of the sleeve is limited by the limiting piece;

[0024] A fastening bolt is installed on the outer end of the sleeve by means of threads to fix the position of the adjusting vertical rod. A connecting rod is fixedly provided at the rear side of the sleeve.

[0025] Further, receiving grooves are provided at both the front and rear ends of the flatbed truck. The flipping mechanism includes a flap provided inside the receiving groove. The thickness of the flap is the same as the thickness of the receiving groove. One end of the flap facing the flatbed truck is movably connected to the inner wall of the receiving groove through a rotating shaft, and the flap is flipped by rotating the flap;

[0026] One end of the connecting rod is fixedly connected to the front end of the front-side flap to install the leveling assembly on the flatbed truck in this way. An installation plate is fixedly provided at the rear end of the rear-side flap. The rice transplanter assembly is installed on the installation plate by bolts. The bottom end of the spring is fixedly connected to the top end of the front-side flap. The sliding rod penetrates through the front-side flap, so that the leveling assembly, the film covering assembly, and the rice transplanter assembly can be flipped by flipping the flap for maintenance. A connecting seat is fixedly provided at the top end of the front-side flap for connecting the rice transplanter to the driving device.

[0027] Further, two fixing parts are provided on one side of the receiving groove close to the flatbed truck. The fixing part includes a driving shaft penetrating through the flatbed truck. The driving shaft is movably connected to the flatbed truck through a bearing, and the driving shaft can thus rotate;

[0028] Two clamping plates are fixedly provided on the driving shaft. One end of the clamping plate extends to contact the flap. The two clamping plates on the fixing part are respectively located at the top and bottom ends of the flap for positioning the flap.

[0029] (III) Beneficial effects

[0030] Compared with the prior art, the present invention provides a rice film-covered transplanter, which has the following

[0031] beneficial effects:

[0032] 1. By storing the thin mud in the storage box, driving the conveying shaft to rotate through the motor, transmitting the thin mud to the shunt box through the conduit, and finally enabling the thin mud to fall on the plastic film corresponding to the discharge chute, so as to press the thin mud on the plastic film, increasing the fixing strength of the plastic film, preventing the plastic film from floating on the water surface under the buoyancy force, and thus avoiding the laying failure caused thereby.

[0033] 2. By converting a relatively wide plastic film in the prior art into multiple relatively narrow plastic films spliced together, the edge positions of adjacent plastic films overlap, ensuring the laying effect. At the same time, the transplanter assembly inserts the seedlings at the overlapping part of two adjacent plastic films. The overlapping part will move away under the thrust force when the seedlings are inserted and generate a gap, avoiding the resistance to transplanting caused by the presence of the plastic film, and there is no need to punch holes in the plastic film for easy transplanting, making transplanting more convenient.

[0034] 3. By arranging a leveling assembly at the front side of the flatbed cart, the V-shaped push plate in the leveling assembly moves synchronously with the flatbed cart, pushing away the water at the front side of the film covering assembly during the movement. In this way, when the film covering assembly at the rear side of the leveling assembly lays the plastic film, there will be less water at the plastic film, avoiding the resistance to the laying of the plastic film between the plastic film and the soil caused by the buoyancy of the water.

[0035] 4. By arranging flap plates at both the front and rear ends of the flatbed cart, and installing the leveling assembly, the film covering assembly, and the transplanter assembly on the front and rear flap plates respectively, the originally downward leveling assembly, the film covering assembly, and the transplanter assembly can be lifted through the rotation of the flap plates, facilitating maintenance. Especially for the film covering assembly originally located at the bottom of the flatbed cart, it can be lifted and is no longer restricted by the space at the bottom of the flatbed cart, making maintenance more convenient.

Detailed implementation manners

[0048] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] To address the deficiencies of the prior art, such as Figures 1-11As shown in the figure, the present invention provides a rice film - mulching transplanter, which includes a flatbed truck 1. A transplanter assembly 4 is installed at the rear end of the flatbed truck 1. A film - mulching assembly 6 for laying a plastic film 606 is provided at the bottom of the flatbed truck 1. A plurality of plastic films 606 on the film - mulching assembly 6 are all wound into a cylindrical shape. Flip mechanisms are provided at both the front and rear ends of the flatbed truck 1, and a pressing mechanism 5 is provided on the flatbed truck 1;

[0050] The pressing mechanism 5 includes a storage tank 501 fixedly provided at the top of the flatbed truck 1. The storage tank 501 is filled with thin mud. A shunt box 507 is provided at the bottom of the flatbed truck 1. Two conduits 505 for transporting thin mud are fixedly provided at the top of the shunt box 507. The top ends of the conduits 505 penetrate the flatbed truck 1 and are fixedly connected to the bottom end of the storage tank 501;

[0051] The bottom end of the shunt box 507 is installed with a bottom plate 509. A plurality of discharge grooves 510 are opened on the bottom plate 509. The thin mud is discharged through the discharge grooves 510. The discharge grooves 510 correspond to the plastic films 606 one by one, and the discharge grooves 510 are located above their corresponding plastic films 606.

[0052] The plastic film 606 is installed at the bottom end of the flatbed truck 1. The plastic film 606 is generally strip - shaped. In the initial state, it is wound into a cylindrical shape and installed at the bottom end of the flatbed truck 1. During the laying process, the plastic film 606 contacts the soil at the bottom of the paddy field, rolls on the soil as the flatbed truck 1 moves, and unfolds the cylindrical plastic film 606 and lays it on the soil at the bottom of the paddy field as it rolls. One end of the plastic film 606 is fixed in the paddy field in advance during laying, so as to ensure that the cylindrical plastic film 606 is pulled and rotated during the movement for laying. The traditional laying method is to lay a relatively wide plastic film 606 at a time, while this film - mulching transplanter transforms a relatively wide plastic film 606 into multiple relatively narrow plastic films 606 and lays them simultaneously.

[0053] Embodiment 1

[0054] Before laying, the thin mud is stored in the storage box 501. The thin mud can be obtained locally from the paddy field. Drain off some of the water to make it more viscous than the original thin mud in the paddy field. Then remove the larger stones and lumps of soil to avoid blockage. The consistency of the thin mud is adjusted by itself to ensure that it can flow and will not disperse completely after entering the water. The thin mud is stored in the storage box 501 and is transported to the shunt box 507 through the conduit 505. An outlet groove 510 corresponding to the plastic film 606 is formed on the bottom plate 509 at the bottom end of the shunt box 507. The shunt box 507 is located above the plastic film 606 and behind the film covering assembly 6. After the plastic film 606 is unfolded and laid in the paddy field, the thin mud in the shunt box 507 will fall through the outlet groove 510 and land on the laid plastic film 606, thereby pressing the thin mud on the plastic film 606, increasing the fixing strength of the plastic film 606, and preventing the plastic film 606 from floating on the water surface under the action of buoyancy, thus avoiding the laying failure caused thereby.

[0055] To facilitate adding thin mud into the storage box 501, as Figure 5 、 6 shown, a cover plate 502 is detachably installed at the top end of the storage box 501, and two motors 503 are fixedly provided at the top end of the cover plate 502;

[0056] A plurality of inclined blocks 506 are fixedly provided at the bottom end inside the storage box 501, and the inclined blocks 506 cause the thin mud in the storage box 501 to converge at the two conduits 505.

[0057] Two connecting shafts 504 are provided inside the storage box 501. The top ends of the connecting shafts 504 extend to the top of the cover plate 502 and are movably connected to the cover plate 502 through bearings. The top ends of the connecting shafts 504 are respectively fixedly connected to the output shafts of the two motors 503;

[0058] The bottom ends of the connecting shafts 504 are fixedly provided with conveying shafts 508. The upper half of the conveying shafts 508 is located in the storage box 501, and the lower half of the two conveying shafts 508 respectively extends into the two conduits 505.

[0059] The thin mud is stored in the storage box 501. When the thin mud needs to be transported, the motor 503 is turned on. The connecting shaft 504 is driven to rotate by the motor 503, and then the conveying shaft 508 is driven. The two ends of the conveying shaft 508 are respectively located in the storage box 501 and the conduit 505. Therefore, after rotation, it can transport the thin mud inside the storage box 501 to the conduit 505, and then introduce it into the shunt box 507.

[0060] To reduce the resistance during rice transplanting, as Figure 1 、 2As shown in Figures 3, 7, 8, and 9, the film covering assembly 6 further includes a fixing plate 604 located at the bottom of the flatbed cart 1. The fixing plate 604 is located on the front side of the shunt box 507. At the bottom end of the fixing plate 604, a plurality of brackets 605 are fixedly provided. The brackets 605 are arranged horizontally, and any two adjacent brackets 605 are staggered front and back.

[0061] The plastic film 606 is arranged inside the brackets 605 and corresponds to the brackets 605 one by one. Sleeve pipes 607 are installed on both sides of the brackets 605 through bearings;

[0062] A plug rod 608 is inserted into the central position of the plastic film 606 wound into a cylindrical shape. Both ends of the plug rod 608 pass through the sleeve pipes 607 on both sides thereof and are connected to the sleeve pipes 607 by bolts;

[0063] The outer edge of any two adjacent plastic films 606 overlaps by one centimeter to avoid the influence of gaps on the laying effect. Each overlapping part corresponds to a row of seedlings, and the seedlings are inserted at the overlapping part of two adjacent plastic films 606.

[0064] A connecting plate 601 is provided on the top of the flatbed cart 1. At the bottom end of the connecting plate 601, two springs 602 and two sliding rods 603 are fixedly provided. The two springs 602 are arranged between the two sliding rods 603;

[0065] The bottom end of the sliding rod 603 extends to the bottom of the flatbed cart 1 and is fixedly connected to the top end of the fixing plate 604. The bottom end of the spring 602 is connected to the front-side turning mechanism. With the elasticity of the spring 602, the plastic film 606 is in full contact with the soil at the bottom of the paddy field for laying.

[0066] The film covering assembly 6 is installed on the turning mechanism. The spring 602 is in a stretched state during the laying process. Therefore, the elasticity of the spring 602 will pull the connecting plate 601 downward, and then push the sliding rod 603 and the fixing plate 604 downward through the connecting plate 601, and make the plastic film 606 located at the bottom of the fixing plate 604 closely adhere to the soil of the paddy field.

[0067] The cylindrical plastic film 606 is placed in the brackets 605. The plug rod 608 passes through the central part of the plastic film 606, which is equivalent to the axis of the plastic film 606. Both ends of the plug rod 608 are fixed on the sleeve pipes 607. Therefore, as the flatbed cart 1 moves, the plastic film 606 will rotate around the plug rod 608, and the plug rod 608 rotates under the action of the sleeve pipes 607. Any two adjacent plastic films 606 are staggered front and back. After the plastic film 606 is laid and unfolded, there will be a one-centimeter overlap at the edge position of any two adjacent plastic films 606, which makes there be no gap between adjacent plastic films 606 under natural conditions and avoids insufficient coverage of the soil due to this.

[0068] Embodiment 2

[0069] And a rice transplanter assembly 4 is installed at the rear side of the flatbed truck 1. The rice transplanter assembly 4 moves along with the flatbed truck 1 and performs rice transplanting after laying the plastic film 606. The rice transplanter assembly 4 is a prior art, such as a rice transplanter with the publication number CN218006982U, which integrates the frame, the horizontal seedling feeding mechanism and the rice transplanting driving mechanism in this prior art. The rice transplanter assembly 4 can plant multiple rows of rice seedlings at one time, and each row of rice seedlings is planted at the overlapping part of the plastic film 606. The rice seedlings are inserted into the paddy field. Therefore, the soil at the bottom of the plastic film 606 is all soft mud. When the rice transplanter inserts the rice seedlings into the soil, the downward thrust of the rice seedlings will cause the two plastic films 606 at the overlapping part to move to their respective sides, thereby generating a fine gap. The rice seedlings are inserted into the soil through this gap, avoiding the resistance to rice transplanting caused by the presence of the plastic film 606, and there is no need to make holes in the plastic film 606 for the convenience of rice transplanting, making rice transplanting more convenient.

[0070] There is an overlapping part between two adjacent plastic films 606. The overlapping part can completely cover the soil under natural conditions. Only at the position where the rice seedlings are inserted, there are fine gaps due to the rice seedlings, and the adjacent two rice seedlings still remain in an overlapping state.

[0071] To reduce the resistance when laying the plastic film 606, as Figure 3 、 7 As shown in FIGS. 10 and 11, a leveling assembly 2 is provided at the front end of the flatbed truck 1. The leveling assembly 2 and the spring 602 are installed on the same flipping mechanism. The leveling assembly 2 includes a pressing plate 201. The pressing plate 201 is horizontal with the ground and contacts the ground during use to level the soil in the paddy field. A V-shaped pushing plate 202 is fixedly provided at the top end of the pressing plate 201. With the thrust of the V-shaped pushing plate 202, the water is temporarily pushed to both sides.

[0072] Two adjusting vertical rods 203 are fixedly provided at the top end of the V-shaped pushing plate 202. A limiting piece is fixedly provided at the top end of the adjusting vertical rods 203. A sleeve 204 is sleeved on the outer end of the adjusting vertical rods 203, and the height of the pressing plate 201 can be adjusted thereby. The sliding range of the sleeve 204 is limited by the limiting piece;

[0073] A fastening bolt is installed at the outer end of the sleeve 204 by means of a thread for fixing the position of the adjusting vertical rods 203. A connecting rod 205 is fixedly provided at the rear side of the sleeve 204.

[0074] The adjusting vertical rod 203 slides up and down through the sleeve 204, thereby adjusting the overall height of the leveling assembly 2 before film mulching and transplanting, so that the bottom end of the pressing plate 201 is in full contact with the soil in the paddy field. In this way, when the flatbed truck 1 is moving, the pressing plate 201 moves along with it on the front side of the flatbed truck 1, scraping the soil in the paddy field flat, so that the laid plastic film 606 is more flat. At the same time, the V-shaped push plate 202 fixed to the bottom end of the pressing plate 201 will push the water on the front side of the flatbed truck 1 during the moving process, causing the water on the front side of the flatbed truck 1 to flow to both sides of the V-shaped push plate 202, thereby pushing the water away in a short time. In this way, when the film mulching assembly 6 behind the leveling assembly 2 lays the plastic film 606, there will be less water at the position of the plastic film 606, avoiding the buoyancy of the water from generating resistance to the laying of the plastic film 606 between the soil and the plastic film 606.

[0075] For the convenience of overhauling the leveling assembly 2, the film mulching assembly 6, and the mounting plate 7, as Figure 1 , 4 , as shown in Figures 10, receiving grooves 10 are provided at both the front and rear ends of the flatbed truck 1. The flipping mechanism includes a flap 8 provided inside the receiving groove 10. The thickness of the flap 8 is the same as that of the receiving groove 10. One end of the flap 8 facing the flatbed truck 1 is movably connected to the inner wall of the receiving groove 10 through a rotating shaft. By rotating the flap 8, the flap 8 can be flipped.

[0076] One end of the connecting rod 205 is fixedly connected to the front end of the front flap 8, thereby mounting the leveling assembly 2 on the flatbed truck 1. The rear end of the rear flap 8 is fixedly provided with a mounting plate 7. The transplanter assembly 4 is mounted on the mounting plate 7 through bolts. The bottom end of the spring 602 is fixedly connected to the top end of the front flap 8. The sliding rod 603 penetrates through the front flap 8, and the length of the sliding rod 603 does not affect the rotation of the flap 8. In this way, the leveling assembly 2, the film mulching assembly 6, and the transplanter assembly 4 can be flipped by flipping the flap 8 for convenient overhaul. A connecting seat 3 is fixedly provided at the top end of the front flap 8 for connecting the transplanter to the driving device.

[0077] The flap 8 is installed in the receiving groove 10 through a rotating shaft, so the flap 8 can rotate under the action of the rotating shaft. The rice transplanter assembly 4 is installed on the rear flap 8, while the leveling assembly 2 and the film mulching assembly 6 are installed on the front flap 8. Therefore, when the flap 8 is lifted upward, the flap 8 can rotate upward around the rotating shaft, causing the leveling assembly 2, the film mulching assembly 6, and the rice transplanter assembly 4 to be lifted upward accordingly. In this way, the originally downward-facing leveling assembly 2, the film mulching assembly 6, and the rice transplanter assembly 4 can be lifted for maintenance. Especially for the film mulching assembly 6 originally located at the bottom of the flatbed truck 1, after being lifted, it can be freed from the space constraints at the bottom of the flatbed truck 1, making the maintenance more convenient. This film mulching rice transplanter itself has no power and needs to be connected to a driving device through the connecting seat 3 on the front flap 8 and move under the drive of the driving device. In reality, a tractor capable of working in paddy fields can be selected as the driving device. The driving device is not limited to a certain type, as long as it is suitable.

[0078] To fix the position of the flap 8, as Figure 10 shown, two fixing members 9 are provided on one side of the receiving groove 10 close to the flatbed truck 1. The fixing member 9 includes a driving shaft 901 passing through the flatbed truck 1. The driving shaft 901 is movably connected to the flatbed truck 1 through a bearing, so the driving shaft 901 can rotate;

[0079] Two clamping plates 902 are fixedly provided on the driving shaft 901. One end of the clamping plate 902 extends to contact the flap 8. The two clamping plates 902 on the fixing member 9 are respectively located at the top and bottom of the flap 8 for positioning the flap 8.

[0080] In the normal use state, the flap 8 is horizontal with the ground. Each flap 8 corresponds to two fixing members 9. At this time, the two clamping plates 902 in the fixing member 9 are respectively located at the top and bottom of the flap 8, clamping the flap 8 between them and restricting the rotation of the flap 8, thereby fixing the flap 8. When the flap 8 needs to be rotated, first rotate the driving shaft 901 and drive the clamping plate 902 to rotate until the clamping plate 902 no longer contacts the flap 8. At this time, the flap 8 is no longer restricted and can rotate.

[0081] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
