Description

Technical Field

[0001] The invention relates to the technical field of agricultural implements, and in particular to a sowing device. Background Art

[0002] In agricultural production, the sowing of crop seeds is a very important link. During the seed sowing process, it is necessary to fully control the spacing between seeds after sowing to maximize the use of land resources and ensure that each seed has sufficient nutrient supply during the growth process. With the development of science and technology, many types of seed sowing devices are currently on the market. However, most of the current sowing devices use motors to drive the transmission and sowing of seeds during sowing. The movement of the device and the transmission and sowing of seeds are relatively independent. When the device stops moving, the seeds are still being transmitted, and the operator needs to manually turn off the motor, which makes the operation more troublesome. In view of this, it is urgent to propose a sowing device to synchronize the transmission and sowing of crop seeds with the movement of the sowing device. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a seeding device to solve the above problems.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0009] The cam is configured to move the two guide wheels simultaneously and the two guide wheels are connected along the travel path of the two wheels, and the two guide wheels are connected along the travel path of the two wheels respectively.

[0010] Furthermore, the control structure includes a push plate and a push column, both of which are installed between the two side plates. The push plate is located at the front opening of the hopper and abuts against the inner side of the conveyor belt. The upper and lower ends of the push plate are respectively bent in an arc shape away from the conveyor belt. The push column is located between the two second connecting rods and its bottom side abuts against the inner side of the conveyor belt.

[0011] Furthermore, the bottom side height of the push column is lower than the bottom side height of the support plates on the two second connecting rods.

[0012] Furthermore, a plurality of mounting holes are evenly distributed around the conveyor belt, a mounting stud is threadedly connected to one side of the mounting seat close to the conveyor belt, and a clamping end is provided at one end of the mounting stud away from the mounting seat.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figure 1-5 As shown, a sowing device provided in this embodiment includes a hopper 1, a transfer structure 2 and a control structure 3.

[0031] The hopper 1 is used for holding the seeds of crops to be sown. The top and the front end of the hopper 1 are open. A bracket 11 is installed at the rear end of the hopper 1. A handle 111 is installed at the top of the bracket 11 and a first roller 112 is installed at the bottom. Side panels 12 are installed at the front ends of both sides of the hopper 1. A first connecting rod 13 is rotatably installed between the tops of the two side panels 12. Two second connecting rods 14 arranged front and back are rotatably installed between the bottoms of the two side panels 12. The connecting line between the first connecting rod 13 and the two second connecting rods 14 is a triangle, one of which is Both ends of the second connecting rod 14 pass through the side plate 12 and are installed with second rollers 141. The outer sides of the first connecting rod 13 and the second connecting rod 14 are surrounded and covered with a conveyor belt 15, and the belt surface of the conveyor belt 15 is in contact with the edges of the front end opening of the hopper 1. The operator holds the handle 111 to push the device, so that the first roller 112 and the second roller 141 can rotate. When the second roller 141 rotates, the conveyor belt 15 can be driven to move through the second connecting rod 14, so that the conveyor belt 15 can continuously contact the open area at the front end of the hopper 1.

[0032] Preferably, in order to prevent seeds from falling from the connection between the front opening of the hopper 1 and the conveyor belt 15 , a rubber sealing strip 18 is provided at the edge of the front opening of the hopper 1 , and the rubber sealing strip 18 fits tightly against the surface of the conveyor belt 15 .

[0033] There are multiple transfer structures 2 evenly distributed around the outer side of the conveyor belt 15, and a through slot 16 for the transfer structure 2 to pass through is opened at the bottom front end of the hopper 1. The transfer structure 2 can be clamped to transport crop seeds or loosened to place or sow crop seeds.

[0034] Preferably, a connecting sleeve 161 is provided at the bottom of the groove 16 for the transfer structure 2 to pass through, and the connecting sleeve 161 is open on one side close to the conveyor belt 15. When one of the transfer structures 2 moves with the conveyor belt 15 and leaves the connecting sleeve 161, the next transfer structure 2 will enter the connecting sleeve 161, which is beneficial to ensure that there is always a transfer structure 2 in the connecting sleeve 161 to block and prevent crop seeds from falling out of the connecting sleeve 161.

[0035] The control structure 3 can control the transfer structure 2 to loosen.

[0036] like Figure 3 and Figure 5 As shown, specifically, support plates 17 are respectively provided at both ends of the first connecting rod 13 and the second connecting rod 14, and the support plates 17 support the conveyor belt 15 away from the surfaces of the first connecting rod 13 and the second connecting rod 14, so that there is a gap between the conveyor belt 15 and the surfaces of the first connecting rod 13 and the second connecting rod 14, and the transfer structure 2 includes a mounting seat 21 and a slider 22, the mounting seat 21 is installed on the outer side of the conveyor belt 15, and track plates 211 are respectively provided on both sides of the outer surface of the mounting seat 21, and the slider 22 is slidably installed between the two track plates 211 along the direction approaching or away from the mounting seat 21, and a bearing is provided at the bottom of the side of the slider 22 away from the mounting seat 21. The connecting plate 221 and the receiving plate 221 are respectively rotatably installed with clamping plates 222 on both sides, and a spring sheet 223 is connected between the bottoms of the two clamping plates 222 to provide elastic force to keep the two clamping plates 222 away from each other, and a movable column 224 is provided on the side of the slider 22 close to the mounting seat 21, and one end of the movable column 224 slides through the mounting seat 21 and the conveyor belt 15 to the inner side of the conveyor belt 15 in sequence, and a spring 225 is installed between the slider 22 and the mounting seat 21 to provide elastic force to pull the slider 22 toward the mounting seat 21. When the slider 22 moves toward the mounting seat 21, the two clamping plates 222 will be pushed by the track plate 211 and rotate close to each other.

[0037] like Figure 2As shown, further, the control structure 3 includes a push plate 31 and a push column 32, and the push plate 31 and the push column 32 are both installed between the two side plates 12. The push plate 31 is located on the inner side of the conveyor belt 15 at the front opening of the hopper 1 and abuts against the conveyor belt 15 at that location. The upper and lower ends of the push plate 31 are respectively bent in an arc shape in the direction away from the conveyor belt 15. The push column 32 is located between the two second connecting rods 14 and its bottom side abuts against the inner side of the conveyor belt 15.

[0038] In specific use, the crop seeds are first placed in the hopper 1. When the operator pushes the device to move, the conveyor belt 15 is driven to move around through the second roller 141 and the second connecting rod 14, so that each transfer structure 2 can move to the front end opening of the hopper 1 through the through slot 16 as the conveyor belt 15 moves. When the transfer structure 2 moves to the front end opening of the hopper 1, the movable column 224 on the transfer structure 2 will be pushed outward by the push plate 31, so that the slider 22 is away from the mounting seat 21. When the two sides of the two clamps 222 lose the constraints of the track plate 211, the two clamps 222 will open under the elastic force of the spring sheet 223, so that the crop seeds can be stuck between the two clamps 222, completing the transfer of the crop seeds. When moving away from the front end opening of the hopper 1, the movable column 224 on the transfer structure 2 will leave the area of ​​the push plate 31, so that the slider 22 will move toward the mounting seat 21 under the elastic force of the spring 225, and the two clamping plates 222 will be pushed by the track plate 211 and rotated close to each other, thereby clamping the crop seeds to prevent the crop seeds from falling during transportation. Until the transfer structure 2 passes the bottom side of the push column 32, that is, when the surface of the conveyor belt 15 and the opening of the clamping plate 222 are both facing the soil below, the movable column 224 on the transfer structure 2 will be pushed outward by the push column 32, so that the two clamping plates 222 are opened again, so that the crop seeds can fall into the soil to complete the sowing, and then the transfer structure 2 will enter the next cycle of seed transportation and sowing.

[0039] The present invention can synchronously drive the conveyor belt 15 to move and transport seeds when the operator pushes the device to move by connecting the second connecting rod 14 to the second roller 141 and the conveyor belt 15, thereby synchronizing the transmission and sowing of crop seeds with the movement of the sowing device, reducing intermediate steps, and not requiring a motor to transmit seeds, saving the use cost of the device, and making the operation convenient and reliable. In addition, the present invention also utilizes the movement of the transfer structure 2 in different areas, and by setting a push plate 31 at the position of the front end opening of the hopper 1 inside the conveyor belt 15 and setting a push column 32 between the two second connecting rods 14, the transfer structure 2 can automatically grab, clamp and sow crop seeds, and the operation is simple and efficient.

[0040] Preferably, the bottom side height of the pushing column 32 is lower than the bottom side height of the support plate 17 on the two second connecting rods 14, so that the height of the conveyor belt 15 located on the bottom side of the pushing column 32 is at the lowest position. When the transfer structure 2 passes through the bottom side of the pushing column 32, it can be inserted downward into the soil, which is conducive to assisting the insertion of crop seeds into the soil.

[0041] like Figure 4 As shown, further, the conveyor belt 15 is evenly distributed with a plurality of mounting holes 151, and a mounting stud 212 is threadedly screwed on one side of the mounting seat 21 close to the conveyor belt 15, and a clamping end 213 is provided at the end of the mounting stud 212 away from the mounting seat 21. By pressing the mounting seat 21 against the outer surface of the conveyor belt 15, and then passing the mounting stud 212 through the mounting hole 151 and screwing it into the mounting seat 21, the mounting seat 21 can be detachably installed, which facilitates the disassembly and maintenance of the transfer structure 2. At the same time, whenever the conveyor belt 15 passes through the first connecting rod 13 or the second connecting rod 14 and turns and deforms, a movable margin can be left between the mounting stud 212 and the mounting hole 151 to prevent damage to the components.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
