Technical Field

[0001] The present invention belongs to the technical field of soybean planting, and specifically relates to a quantitative seed sowing device for soybean planting. Background Technique

[0002] Soybean is an annual herbaceous plant and is the most important legume in the world. Its plant height is 30 - 90 cm, the stem is erect and densely covered with brown long stiff hairs, the leaves are pinnate trifoliate, the flowers are purple or white, the pods are densely covered with villi, the seed colors are diverse, including soybeans, green beans, black beans, etc. Among them, soybeans are the most common type of soybean. Soybeans can be made into soy milk, tofu, soybean oil, soy sauce, etc. Its plant protein content is as high as 35% - 40%, making it an important protein source for vegetarians;

[0003] When planting soybeans in the prior art, a soybean planter is often used. Using mechanical planting can not only improve the planting efficiency but also greatly reduce labor consumption. However, using a planting machine often requires a sufficient area of soybean planting land. For household planting, the area of soybean planting land is small, and it is impossible to use a planting machine for planting. Therefore, when planting soybeans on a small area of land, manual digging and quantitative seed sowing are still used for planting. This planting method has low efficiency and high manual labor consumption. Summary of the Invention

One end of each of the two inclined straight rods is fixedly connected to the outer walls at both ends near the bottom of the material cylinder. A rectangular long groove is penetrated and opened at one end of the material cylinder. An electric cylinder is fixedly connected to the top side wall of the trolley. An L-shaped plate is fixedly connected to the top of the electric cylinder. The plate body of the L-shaped plate is in sliding fit with the inner wall of the rectangular long groove. A quantitative feeding structure is provided in the inner wall of the material cylinder.

[0006] Preferably, the quantitative feeding structure includes a pressing plate fixedly connected to the outer wall at the bottom end of the L-shaped plate. The pressing plate is in sliding fit with the inner wall of the material cylinder. A screw rod can be threadedly connected to the pressing plate. A first rotating rod is fixedly connected to the bottom end of the screw rod.

[0007] Preferably, a first feeding tray is fixedly connected to the bottom end of the first rotating rod. The first feeding tray is in fitting and rotating connection with the inner wall of the material cylinder. A second feeding tray is also in fitting and rotating connection with the bottom end of the first feeding tray. The second feeding tray is fixedly connected to the inner wall of the material cylinder. And discharge holes are formed through the two side plates of the first feeding tray and the second feeding tray.

[0008] Preferably, two sliders are in fitting and sliding connection with the rod body of the first rotating rod near the bottom. A plurality of balls are sleeved around the outer walls of the two sliders in a circumferential manner. And hinge plates are fixedly connected in combination between the two groups of balls.

[0009] Preferably, a plurality of arc-shaped plates are fixedly connected in a circumferential manner in the inner wall of the material cylinder. Each hinge plate can be in fitting and sliding connection with each arc-shaped plate intermittently. A telescopic cylinder and an elastic member are fixedly connected in combination between the two sliders.

[0010] Preferably, the other ends of the outer walls of the two sliders can be in intermittent fitting connection with two abutting plates. Both of the two abutting plates are fixedly connected to the rod body of the first rotating rod.

[0011] Preferably, meshing components are respectively arranged on one side rod bodies of each inclined straight rod. The meshing components are specifically composed of two meshing bevel gears. One bevel gear is fixedly connected to the side rod body of the inclined straight rod. And the other bevel gear is fixedly connected to a second rotating rod.

[0012] Preferably, a protective cylinder is rotatably connected to the rod body of the second rotating rod. One end inner wall of the protective cylinder is sleeved with the other end rod body of the inclined straight rod in a movable manner. And a protective cylinder is also sleeved on the rod body of the inclined straight rod. The outer wall of the top end of the protective cylinder is sleeved with the bottom end rod body of the second rotating rod in a movable manner.

[0013] Preferably, a turntable is fixedly connected to the top end rod body of the second rotating rod. A rotating handle is fixedly connected to the side wall of the top end of the turntable. A rectangular groove plate is in fitting and sliding connection with the rod body of the rotating handle. And a sliding rod is fixedly connected to one end outer wall of the rectangular groove plate.

[0014] Preferably, a block plate is slidably connected to the rod body of the sliding rod. The top plate of the block plate is fixedly connected to the bottom side wall of the trolley.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In the present invention, the pressure plate moves downward in the barrel until it meshes with the screw. During the continuous downward movement of the pressure plate, the screw is driven to rotate. The rotating screw will synchronously drive the first rotating rod and the first feeding tray to rotate. Once the two discharge holes on the first feeding tray are aligned with the two discharge holes on the second feeding tray, the soybeans in the barrel can be sown. Thus, through intermittent rotational alignment, quantitative feeding of soybeans can be achieved.

[0017] When the first rotating rod rotates in the present invention, it drives two sliders and multiple hinged plates to rotate. When the passively rotating hinged plates contact the arc-shaped plate, after being passively forced and squeezed, the angle changes are generated on the outer wall of the sliders through the balls installed at both ends of the arc-shaped plate. At the same time, the stressed arc-shaped plate will drive the two sliders to translate in opposite directions on the first rotating rod, thereby stretching the connected telescopic cylinder and elastic member. The elastic member facilitates the subsequent reset of the two sliders and multiple hinged plates, while the telescopic cylinder is to prevent soybeans from getting stuck in the elastic member. Thus, the repeated angle change of the hinged plates can stir the soybeans stacked on each other by gravity, facilitating sowing and feeding.

[0018] When the second rotating rod rotates in the present invention, it drives the turntable and the rotating handle to rotate synchronously. The rotating handle in the rotating state will repeatedly slide on the inner wall of the rectangular groove plate, thereby driving the rectangular groove plate and the sliding rod to perform guiding translation under the limitation of the block plate. Thus, it drives the connected striking plate to perform guiding translation on the rod body of the inclined straight rod, and then repeatedly strikes the outer wall of the barrel near the bottom, causing it to repeatedly generate intermittent vibrations, thereby performing a second-level auxiliary feeding on the soybeans in the barrel, preventing blockage and enabling smooth quantitative feeding from the bottom of the barrel.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 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.

[0029] As Figures 1 to 6 shown, the present invention provides a quantitative seed planting device for soybean planting, including a trolley 1. Oblique straight rods 11 are provided on both sides below the trolley 1. Rolling wheels 12 are fixedly connected to the rod bodies of the two oblique straight rods 11. The rod bodies of the two oblique straight rods 11 are specifically divided into two sections, and each two sections of rod bodies are movably sleeved. A planting part 2 is further provided on the trolley 1. The planting part 2 includes a cylinder 21 fixedly connected to the trolley 1 in a penetrating manner. One ends of the two oblique straight rods 11 are respectively fixedly connected to the outer walls of the two ends of the cylinder 21 near the bottom. A rectangular long groove 22 is penetrated and opened at one end of the cylinder 21. An electric cylinder 23 is fixedly connected to the top side wall of the trolley 1. An L-shaped plate 24 is fixedly connected to the top end of the electric cylinder 23. The plate body of the L-shaped plate 24 is in sliding fit with the inner wall of the rectangular long groove 22. A quantitative feeding structure is provided in the inner wall of the cylinder 21.

[0030] Adopting the above solution: By putting soybeans into the cylinder 21, the soybean seeds should not cross the rectangular long groove 22, and then start the electric cylinder 23 to drive the L-shaped plate 24 to move downward in a limited position in the rectangular long groove 22, thereby driving the pressure plate 25 to move downward in the cylinder 21. By manually pushing the trolley 1, the rolling wheels 12 installed at both ends are in direct contact with the ground and roll, so as to directly drive a section of the corresponding oblique straight rod 11 to rotate synchronously, thus facilitating the manual soybean planting operation for small-acre fields.

[0031] The quantitative feeding structure includes a pressing plate 25 fixedly connected to the outer wall of the bottom end of the L-shaped plate 24. The pressing plate 25 is in sliding connection with the inner wall of the barrel 21 in a fitting manner. A screw rod 26 can be threadedly connected to the pressing plate 25. A first rotating rod 27 is fixedly connected to the bottom end of the screw rod 26. A first feeding tray 28 is fixedly connected to the bottom end of the first rotating rod 27. The first feeding tray 28 is in rotational connection with the inner wall of the barrel 21 in a fitting manner. A second feeding tray 29 is also in rotational connection with the bottom end of the first feeding tray 28 in a fitting manner. The second feeding tray 29 is fixedly connected to the inner wall of the barrel 21. And discharge holes 230 are formed through both side plates of the first feeding tray 28 and the second feeding tray 29.

[0032] Adopting the above scheme: The pressing plate 25 moves downward in the barrel 21 until it meshes with the screw rod 26. And during the continuous downward movement of the pressing plate 25, the screw rod 26 is driven to rotate. The rotating screw rod 26 will synchronously drive the first rotating rod 27 and the first feeding tray 28 to rotate. Once the two discharge holes 230 on the first feeding tray 28 are aligned with the two discharge holes 230 on the second feeding tray 29, the soybeans in the barrel 21 can be sown. Thus, through intermittent rotational alignment, the quantitative feeding of soybeans can be achieved.

[0033] Two sliders 231 are in sliding connection with the rod body of the first rotating rod 27 near the bottom. A plurality of balls 232 are movably sleeved around the outer walls of the two sliders 231 in a circumferential manner. Hinge plates 233 are fixedly connected between the two groups of balls 232. A plurality of arc-shaped plates 234 are fixedly connected in a circumferential manner in the inner wall of the barrel 21. Each hinge plate 233 can be in intermittent sliding connection with each arc-shaped plate 234. A telescopic cylinder 235 and an elastic member 236 are fixedly connected between the two sliders 231. The outer walls of the other ends of the two sliders 231 can be intermittently in contact connection with two abutting plates 237. Both of the two abutting plates 237 are fixedly connected to the rod body of the first rotating rod 27.

[0034] Adopting the above scheme: When the first rotating rod 27 rotates, it will also drive the two sliders 231 and the plurality of hinge plates 233 fixedly connected between the two sliders 231 to rotate. When the passively rotating hinge plate 233 contacts the arc-shaped plate 234, after being passively forcefully pressed, the angle is changed on the outer wall of the slider 231 through the balls 232 installed at both ends of the arc-shaped plate 234. At the same time, the stressed arc-shaped plate 234 will also drive the two sliders 231 to translate in opposite directions on the first rotating rod 27, thereby stretching the connected telescopic cylinder 235 and the elastic member 236. The elastic member 236 is convenient for driving the two sliders 231 and the plurality of hinge plates 233 to reset later, and the telescopic cylinder 235 is to prevent soybeans from getting stuck in the elastic member 236. Thus, the repeated angle change of the hinge plate 233 can stir the soybeans piled up by mutual gravity, facilitating sowing and feeding.

[0035] On one side of each inclined straight rod 11, a meshing component 238 is respectively provided. Specifically, the meshing component 238 is composed of two meshing bevel gears. One bevel gear is fixedly connected to the rod body on one side of the inclined straight rod 11, and a second rotating rod 239 is fixedly connected to the other bevel gear. A protective cylinder 240 is rotatably connected to the rod body of the second rotating rod 239. One end inner wall of the protective cylinder 240 is movably sleeved on the other end rod body of the inclined straight rod 11, and the rod body of the inclined straight rod 11 is also movably sleeved with the protective cylinder 240. The outer wall of the top end of the protective cylinder 240 is movably sleeved on the bottom end rod body of the second rotating rod 239.

[0036] With the above scheme: The rotating rod body of the inclined straight rod 11 will directly drive the meshing component 238 to transmit power, thereby driving the second rotating rod 239 to rotate in a positioned manner on the protective cylinder 240 and the protective cylinder 240. The function of the protective cylinder 240 is to prevent soil from entering the meshing component 238 and affecting the meshing part between the two bevel gears, so as to protect it.

[0037] A turntable 241 is fixedly connected to the top end rod body of the second rotating rod 239. A rotating handle 242 is fixedly connected to the side wall of the top end of the turntable 241. A rectangular groove plate 243 is slidably attached to the rod body of the rotating handle 242. A sliding rod 244 is fixedly connected to the outer wall of one end of the rectangular groove plate 243. A block plate 245 is slidably connected to the rod body of the sliding rod 244. The top plate body of the block plate 245 is fixedly connected to the bottom side wall of the trolley 1. A striking plate 246 is fixedly connected to the other end rod body of the sliding rod 244. The striking plate 246 is intermittently attached to the outer wall of the feeding cylinder 21 near the bottom. One side plate body of the striking plate 246 is slidably connected through the rod body of the inclined straight rod 11.

[0038] With the above scheme: The rotation of the second rotating rod 239 will drive the turntable 241 and the rotating handle 242 to rotate synchronously. The rotating handle 242 in the rotating state will repeatedly slide on the inner wall of the rectangular groove plate 243, thereby driving the rectangular groove plate 243 and the sliding rod 244 to perform guiding translation under the limitation of the block plate 245, thereby driving the connected striking plate 246 to perform guiding translation on the rod body of the inclined straight rod 11, and then repeatedly striking the outer wall of the feeding cylinder 21 near the bottom, causing it to repeatedly generate intermittent vibrations, so as to perform a second-level auxiliary feeding on the soybeans in the feeding cylinder 21, prevent it from being blocked, and enable smooth quantitative feeding from the bottom of the feeding cylinder 21.

[0039] Working principle and usage process of the present invention: Put soybeans into the feed cylinder 21, and the soybean seeds should not cross the rectangular long groove 22. Then start the electric cylinder 23 to drive the L-shaped plate 24 to move downward in a limited way in the rectangular long groove 22, thereby driving the pressing plate 25 to move downward in the feed cylinder 21 until it meshes with the screw 26. And during the continuous downward movement of the pressing plate 25, the screw 26 is driven to rotate. The rotating screw 26 will synchronously drive the first rotating rod 27 and the first feeding tray 28 to rotate. Once the two discharge holes 230 on the first feeding tray 28 are aligned with the two discharge holes 230 on the second feeding tray 29, the soybeans in the feed cylinder 21 can be sown. Thus, through intermittent rotation and alignment, quantitative feeding of soybeans can be achieved. When the first rotating rod 27 rotates, it will also drive the two sliders 231 and the multiple hinge plates 233 jointly connected between the two sliders 231 to rotate. When the passively rotating hinge plates 233 contact the arc angle plate 234, after being passively forced and squeezed, the angle is changed on the outer wall of the slider 231 through the balls 232 installed at both ends of the arc angle plate 234. At the same time, the stressed arc angle plate 234 will drive the two sliders 231 to translate in opposite directions on the first rotating rod 27, thereby stretching the connected telescopic cylinder 235 and the elastic member 236. The elastic member 236 facilitates the subsequent reset of the two sliders 231 and the multiple hinge plates 233, while the telescopic cylinder 235 is to prevent soybeans from getting stuck in the elastic member 236. When the two sliders 231 touch the corresponding installed abutment plates 237, it means that the hinge plates 233 have been squeezed to the maximum extent. Thus, the repeated angle change of the hinge plates 233 can stir the soybeans stacked by mutual gravity, facilitating sowing and feeding;

[0040] Manually push the cart 1 by hand. The two ends are installed with rollers 12 that directly contact the ground and roll, so as to directly drive a section of the rod body of the corresponding inclined straight rod 11 to rotate synchronously. The rotating rod body of the inclined straight rod 11 will directly drive the transmission of the meshing component 238, thereby driving the second rotating rod 239 to rotate in a positioned manner on the protective cylinder 240 and the protective cylinder 240. The rotation of the second rotating rod 239 will drive the turntable 241 and the rotating handle 242 to rotate synchronously. And the rotating handle 242 in the rotating state will repeatedly slide on the inner wall of the rectangular groove plate 243, thereby driving the rectangular groove plate 243 and the sliding rod 244 to perform guiding translation under the limitation of the block plate 245, thereby driving the connected striking plate 246 to perform guiding translation on the rod body of the inclined straight rod 11, and then repeatedly strike the outer wall of the feed cylinder 21 near the bottom, causing it to repeatedly generate intermittent vibrations, so as to perform a second-level auxiliary feeding on the soybeans in the feed cylinder 21, avoid jamming, and smoothly perform quantitative feeding from the bottom of the feed cylinder 21.
