Description

Technical Field

[0001] The utility model relates to the technical field of sowing, in particular to seed sowing equipment for rice planting. Background Art

[0002] There are generally two sowing methods in the process of sowing rice, namely manual sowing and mechanical sowing; manual sowing is the sowing of rice or wheat seeds manually, while mechanical sowing is mostly the sowing of rice or wheat seeds through mechanical devices.

[0003] At present, most of the mechanical sowing equipment on the market are arranged horizontally and in line during operation, so that the rice can be kept in a straight line after sowing. For example, a Chinese patent (publication number: CN220528516U) discloses a rice seeder, which includes a traction frame, a rotating shaft is rotatably matched inside the traction frame, walking wheels are fixed at both ends of the rotating shaft, a plurality of sowing cylinders are fixed on the peripheral side of the rotating shaft, and a plurality of grooves are opened on the peripheral side of the sowing cylinder.

[0004] During the use of the above patent, it is necessary to pour the seeds into the interior of the storage box, and then the seeds are allowed to flow out continuously from the interior of the box under the action of the subsequent structure. However, the above patent and traditional sowing devices on the market have the following disadvantages during use; for example, when working from one end of the ground to the other end, since the mobile equipment frame sowing equipment is long and needs to turn, in order to ensure the sowing effect, the sowing device will stop working, and then the operator will adjust the tractor or manually adjust the sowing device, and the process is relatively time-consuming. In addition, since manual adjustment requires the cooperation of multiple people to complete the operation, the process is relatively difficult.

[0005] Secondly, for example, a Chinese patent (publication number: CN217936487U) discloses a reciprocating unidirectional sowing device for rice planting, including a mounting plate, which is mounted on an external sowing vehicle. During use, the sowing device used in this patent requires the rice seeds to fall into the slot by themselves. However, during use, it is inevitable that the seeds will be stuck in the leakage holes of the material box. For example, if the inside of a water bottle on the market is filled with marbles, the marbles will be stuck in the bottle mouth when it is placed upside down. However, in the above-mentioned patent, there is no disturbance device installed inside the material box. Therefore, the above situation is inevitable during use. Secondly, the traditional sowing devices on the market are mostly fixed in structure and cannot move laterally, so that the spacing between the sown seeds cannot be adjusted according to the different types of seeds.

[0037] By adopting the above technical scheme, there are generally two sowing methods in the process of sowing rice, namely manual sowing and mechanical sowing. The traditional sowing devices on the market are mostly horizontal structures and fixed in use. Therefore, during use, after working from one end of the field to the other end, the sowing device needs to stop working, and then the tractor takes the sowing device for adjustment. The second method is manual adjustment, but due to its bulky structure, manual adjustment is more time-consuming. The structure of the device is as follows, including a slide rod 1, the front end of the slide rod 1 is an opening device, and a plug 101 is slidably installed inside the front end opening of the open slide rod 1, which is used to block the opening. The left end of the slide rod 1 is fixedly installed with a bracket 2, and the bracket 2 can be regarded as a triangular structure. Wheel hubs 3 are rotatably installed at the front and rear ends of the lower part of the slide rod 1 and the inner left side of the bracket 2, so that the slide rod 1 and the bracket 2 can be regarded as a triangular structure, so that the tractor can carry the bracket 2 for moving operations during subsequent use. Secondly, a slide 4 is slidably installed inside the slide groove on the upper end surface of the slide rod 1, and symmetrical support plates 5 are fixedly installed at the front and rear positions near the edges of the upper end surface of the slide 4. In addition, two vertical plates 41 are fixedly installed at the upper end surface of the slide 4 near the right edge, and an adjusting motor 42 is fixedly installed on the upper right side of one of the vertical plates 41, and a screw 43 is fixedly installed on the output shaft of the adjusting motor 42, and the screw 43 is located on the left side of the vertical plate 41 (two vertical plates 41 are located on the inner sides of the two support plates 5), and a slide rod 44 is fixedly installed on the left side of the other vertical plate 41.

[0038] In addition, a frame 6 is slidably installed on the inner side of the two side vertical plates 41, and the front and rear ends of the left side of the frame 6 protrude outward, and the protruding positions are slidably installed on the circumferential surfaces of the screw 43 and the slide bar 44 respectively. During use, the screw 43 can drive the frame 6 to perform horizontal linear motion, and the slide bar 44 can prevent the frame 6 from rotating synchronously with the screw 43. Then, three rotating shafts 62 are rotatably installed on the inner side of the frame 6, which are respectively located on the left side, right side and corner of the inner side of the frame 6. Secondly, a first motor 61 is fixedly installed at the corner position of the front end face of the frame 6, and the output shaft of the first motor 61 is fixedly connected to the rotating shaft 62 at the inner corner position of the frame 6. Then, a conveying belt 7 is rotatably installed on the circumferential surface of the rotating shaft 62, and a plurality of limit blocks 71 are evenly and fixedly installed on the outer side of the conveying belt 7, so that the outer side of the conveying belt 7 is divided into grooves of uniform size for receiving the rice seeds.

[0039] Then, a protective cover 10 is fixedly installed in the middle position of the inner side of the support plate 5, and then an inlet 11 and an outlet 12 are opened on the circumferential surface of the protective cover 10, and the inlet 11 and the outlet 12 are in a straight line, and the interior of the protective cover 10 is a cavity state, and a feed tray 9 is rotatably installed inside the cavity, and a plurality of material grooves 91 are evenly opened on the circumferential surface of the feed tray 9, and the opening size of the material grooves 91 is consistent with the size of the inlet 11 and the outlet 12, and then a servo motor 8 is fixedly installed in the middle position of the front end surface of the support plate 5, and the output shaft of the servo motor 8 extends to the interior of the protective cover 10 and is fixedly connected to the center position of the front end surface of the feed tray 9, so that the feed tray 9 can rotate inside the protective cover 10.

[0040] In addition, a forward and reverse motor 13 is fixedly installed on the front end surface of the upper end of the support plate 5, and the forward and reverse motor 13 is located above the servo motor 8, and then a material box 15 is fixedly installed on the inner side of the upper part of the support plate 5, and a drop opening 151 is opened on the lower end surface of the material box 15, and the drop opening at the lower end of the material box 15 is in a state of fitting with the feed opening 11 on the circumferential surface of the protective cover 10. Therefore, during use, the rice seeds inside the material box 15 can pass through the drop opening 151 and enter the inside of the feed opening 11. Then it passes through the feed inlet 11 and enters the interior of the material trough 91. Secondly, a disturbance plate 14 is fixedly installed on the circumferential surface of the output shaft of the forward and reverse motor 13, and the disturbance plate 14 is located inside the material box 15, so that the rice seeds inside the material box 15 can be disturbed, so as to avoid the rice seeds being blocked inside the drop port 151; when in use, the tractor and the bracket 2 are connected by a device, so that the subsequent structure can be moved, and then the bracket 2 and the slide rod 1 are moved synchronously, and in the process of movement, the slide 4 needs to be slidably installed in the convex groove on the upper end surface of the slide rod 1, so that the sowing device can be installed on the upper end surface of the slide rod 1. In the process of use, the forward and reverse motor 13 is started, and the output shaft of the forward and reverse motor 13 will drive the disturbance plate 14 to perform a fan-shaped movement, so as to be able to move the rice seeds inside the material box 15, so as to avoid the clogging of the rice seeds, and then the rice seeds will continue to pass through the drop port 151 into the interior of the feed inlet 11, and then the servo motor 8 is started. The output shaft of the servo motor 8 will rotate synchronously with the feeding tray 9, so that the material trough 91 on the circumferential surface of the feeding tray 9 can be in a through state with the feeding port 11, so that the rice seeds can fall into the inside of the material trough 91, and then driven by the feeding tray 9, the material trough 91 containing the rice seeds will rotate 180 degrees, so that its opening can be through with the discharge port 12, so that the rice seeds in the material trough 91 pass through the discharge port 12 and fall into the grooves of the two limit blocks 71 of the conveyor belt 7.

[0041] Then the first motor 61 is started, and the first motor 61 drives the conveyor belt 7 to rotate on the circumferential surface of the rotating shaft 62, so that the conveyor belt 7 and the rice seeds move synchronously. After the conveyor belt 7 brings the rice seeds to the rightmost position on the inner side of the frame 6, the conveyor belt 7 with the rice seeds will rotate with the limit block 71, so that the rice seeds can be sown into the field, and the reciprocating operation is continued. Then, when the operation is carried out, when the operation reaches one end of the field, the adjusting motor 42 is started, and the output shaft of the adjusting motor 42 will rotate synchronously with the screw 43, so that the most The left ends of the frames 6 at the rear and middle positions gradually approach the bracket 2 until the multiple frames 6 form a staircase-like structure, so that the sowing device can turn when operating at the end of the field without stopping the equipment, thereby manually transporting the equipment and saving time and time for adjusting the equipment; compared with traditional sowing devices on the market, during use, the present device can make structural adjustments to a single sowing device according to the actual situation on site, thereby avoiding the innermost sowing device from sowing more rice seeds underneath it during the turning process.

[0042] Specifically, Figures 1 to 6 As shown, the output shaft of the first motor 61 is fixedly connected to the rotating shaft 62 in the middle of the inner side of the frame 6, the conveying belt 7 is rotatably mounted on the circumferential surface of the rotating shaft 62, and a plurality of limit blocks 71 are evenly and fixedly mounted on the outer side of the conveying belt 7, an inlet 11 and an outlet 12 are provided on the circumferential surface of the protective cover 10, and the inlet 11 and the outlet 12 are in a symmetrical state, a feeding tray 9 is rotatably mounted inside the protective cover 10, and a plurality of material troughs 91 are evenly provided on the circumferential surface of the feeding tray 9; a drop opening 151 is provided at the center position of the lower end of the material box 15, a forward and reverse motor 13 is fixedly mounted on the upper end of the outer side of the support plate 5, a disturbance plate 14 is fixedly mounted on the output shaft of the forward and reverse motor 13, and the disturbance plate 14 is located inside the material box 15, a servo motor 8 is fixedly mounted on the outer side of the support plate 5, and the servo motor 8 is located below the forward and reverse motor 13, and the output shaft of the forward and reverse motor 13 is fixedly connected to the center position of the feeding tray 9.

[0043] By adopting the above-mentioned technical scheme, most of the traditional sowing devices on the market are arranged in a horizontal row. Therefore, during use, the sowing device cannot be changed in position and structure, which makes the sowing device relatively simple, and most of the sowing devices on the market have a material box 15 inside without a disturbance device, which makes it easy for the rice seeds inside the material box 15 to block the position of the outlet, so that manual inspection and cleaning are required at regular intervals during operation to avoid the rice seeds blocking the outlet; during use of the device, the sowing device can be changed in real time under the action of the slide rod 1, and the distance between the two slides 4 can be adjusted during use, so as to adjust the distance between the overall sowing devices, and then the vertical distance between the rice seeds can be increased or decreased, so that the equipment can meet the needs of different sites. The first is to meet the needs of different spacing between rice seeds and the practicality of the incremental equipment; secondly, during use, the output shaft of the forward and reverse motor 13 will rotate with the disturbance plate 14, so that the rice seeds inside the material box 15 can be in a state of motion at all times, so as to avoid the rice seeds blocking the drop port 151; under the action of the forward and reverse motors 13, the disturbance plate 14 and other structures of the above-mentioned structure, the rice seeds inside the material box 15 can be disturbed uninterruptedly, so as to avoid the rice seeds being stuck in the drop port 151, thereby ensuring the smooth falling of the rice seeds; secondly, with the cooperation of the slide 4, the slide rod 1 and other structures, the sowing equipment can be added and reduced according to different types of rice seeds, so that the spacing between the sowing equipment can be changed during use, so as to change the spacing between the rice seeds.

[0044] Working principle: First, the bracket 2 is connected to the external moving device, so that the bracket 2 can move the position with the slide rod 1.

[0045] Then the slide 4 is synchronously installed on the upper end surface of the slide rod 1 with the support plate 5 and the frame 6.

[0046] Secondly, start the forward and reverse motor 13 to make the disturbance plate 14 rotate in a fan shape inside the material box 15, and then the rice seeds fall into the inside of the protective cover 10, and then driven by the feeding tray 9 and the material trough 91, they can fall into the inside of the limit block 71 of the conveyor belt 7, and then the conveyor belt 7 can fall to the ground.

[0047] Finally, the regulating motor 42 is started so that the conveyor belt 7 can form a staircase structure, so that the inner and outer spreading devices can be at the same frequency when the spreading device turns.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
