Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically relating to a sowing device based on wheat planting. Background Technology

[0002] Wheat is an important food crop and a staple food in northern China, which has a significant impact on people's diet.

[0003] Nowadays, wheat seeders have gradually replaced traditional manual sowing, greatly improving sowing speed and efficiency. The wheat sowing device mainly includes a seed metering device, a furrow opener, and a press wheel. The furrow opener first creates furrows in the soil for the seeds to fall into. Then the seed metering device is responsible for discharging the wheat seeds from the seed box into the soil. Finally, the press wheel compacts the soil after sowing to ensure that the seeds are in full contact with the soil.

[0004] However, in actual use, if the seed box contains a lot of impurities or debris, or if the aperture of the seed metering device is too small, it may block the holes or channels of the seed metering device. This will prevent the seeds from being discharged normally, resulting in unsown gaps in the furrows, which will affect the uniform distribution and yield of wheat crops. Therefore, a seeding device based on wheat planting is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sowing device based on wheat cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seeding device based on wheat planting, comprising:

[0007] The device body includes a frame, a front wheel, and a rear wheel, with the front wheel and the rear wheel mounted on the lower end face of the frame;

[0008] A trenching structure is installed below the vehicle frame;

[0009] The seed metering structure includes a seed metering box, seed metering tubes, ball plugs, a connecting rod, pulleys, a cam, and an anti-clogging post. The seed metering box is installed below the frame and behind the trenching structure. The seed metering box has multiple spaced-apart seed outlets. Multiple seed metering tubes are provided, spaced apart on the lower surface of the seed metering box and all communicating with the seed outlets. Multiple ball plugs are provided and placed inside the seed metering box. The connecting rod connects to the multiple ball plugs, and the cross-sectional diameter of each ball plug is larger than the seed outlet. The diameter of the tube is specified. The two ends of the connecting rod are slidably connected to the inner wall of the seed metering box. Two pulleys and two cams are provided. The two pulleys are respectively installed at the two ends of the connecting rod. The two cams are rotatably placed on the opposite side walls of the seed metering box. The pulleys are in contact with the side walls of the cams. Multiple anti-blocking columns are provided. The anti-blocking columns are located on the side of the ball plug away from the connecting rod and are placed inside the seed metering tube. The cross-sectional diameter of the anti-blocking column is smaller than the diameter of the seed metering tube. The cams are coaxially connected to the rear wheel.

[0010] As a preferred embodiment, the main body of the device further includes a seed box and a seed inlet tube. The side of the seed box has multiple spaced seed inlets. The seed box is mounted on top of the frame. The seed inlet tube is inclined and connected to the seed box and the seed inlets.

[0011] As a preferred embodiment, the trenching structure includes trenching shovels and rotating rods, the rotating rods being rotatably mounted on the vehicle frame, and multiple trenching shovels being provided, with the multiple trenching shovels being installed at intervals on the rotating rods.

[0012] As a preferred embodiment, the main body of the device further includes a driving wheel, a driven wheel, and a transmission belt. There are two driving wheels, two driven wheels, and two transmission belts. The driving wheel is installed on the front wheel, and the two driven wheels are respectively installed on the two ends of the rotating rod. The transmission belt connects the driving wheel and the driven wheel.

[0013] As a preferred embodiment, the main body of the device also includes a press wheel, which is rotatably mounted at the rear of the seed metering box.

[0014] As a preferred embodiment, the spacing between the plurality of trenching shovels, the plurality of ball plugs, and the plurality of seed inlet tubes is all the same.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a seed metering structure comprising a seed metering box, a seed metering tube, a ball plug, a connecting rod, a pulley, a cam, and an anti-blocking post. The seed metering box has a seed inlet, and the connecting rod is connected to the ball plug. The two ends of the connecting rod are slidably connected to the inner wall of the seed metering box. The cam is rotatably positioned in the seed metering box, and the pulley is in contact with the side wall of the cam. The anti-blocking post is located on the ball plug, and the cam is coaxially connected to the rear wheel. When the pulley gradually slides along the circumferential side wall of the cam with a smaller radius, the connecting rod connected to the pulley moves downward toward the seed inlet, thereby causing the ball plug to seal the seed inlet. At this time, wheat seeds cannot fall from the seed inlet. Simultaneously, the anti-blocking post connected to the ball plug also moves downward in the seed metering tube. In this way, the blockage in the seed metering tube is pushed out by the downward-moving anti-blocking post, preventing subsequent wheat seeds from being unable to be discharged from the blocked seed metering tube into the furrow, thus ensuring wheat yield.

[0017] This invention features a ditching structure including ditching shovels and a rotating rod. The rotating rod is rotatably mounted on a frame, and multiple ditching shovels are spaced apart on the rotating rod. Upon startup, the front wheel is driven to rotate, moving the frame, ditching structure, and seeding structure mounted on the frame forward. The rotating front wheel drives the drive wheel to rotate, which, via a transmission belt, causes the rotating rod connected to the driven wheel to rotate as well. This, in turn, drives the multiple ditching shovels mounted on the rotating rod to rotate, creating multiple spaced furrows in the soil to facilitate subsequent sowing. Attached Figure Description

Multiple seed metering pipes 32 are provided, spaced apart on the lower surface of the seed metering box 31, and all are connected to the seed outlets 311. Multiple ball plugs 33 are provided and placed inside the seed metering box 31. The connecting rod 34 connects to multiple ball plugs 33. The cross-section of the ball plug 33 is straight. The diameter is larger than the diameter of the seed inlet 311. The two ends of the connecting rod 34 are slidably connected to the inner wall of the seed metering box 31. There are two pulleys 35 and two cams 36. The two pulleys 35 are respectively installed at the two ends of the connecting rod 34. The two cams 36 are rotatably placed on the opposite side walls of the seed metering box 31. The pulleys 35 and the side walls of the cams 36 are in contact. There are multiple anti-blocking columns 37. The anti-blocking columns 37 are located on the side of the ball plug 33 away from the connecting rod 34 and are placed inside the seed metering tube 32. The cross-sectional diameter of the anti-blocking column 37 is smaller than the diameter of the seed metering tube 32. The cam 36 is coaxially connected to the rear wheel 13.

[0031] The main body of the device 1 also includes a seed box 14 and a seed inlet pipe 15. The side of the seed box 31 has a plurality of spaced seed inlets 312. The seed box 14 is mounted on the top of the frame 11. The seed inlet pipe 15 is inclined and connected to the seed box 14 and the seed inlets 312.

[0032] The trenching structure 2 includes a trenching shovel 21 and a rotating rod 22. The rotating rod 22 is rotatably mounted on the frame 11. Multiple trenching shovels 21 are provided, and multiple trenching shovels 21 are installed at intervals on the rotating rod 22.

[0033] The main body 1 of the device also includes a driving wheel 16, a driven wheel 17 and a transmission belt 18. There are two driving wheels 16, two driven wheels 17 and two transmission belts 18. The driving wheel 16 is installed on the front wheel 12, the two driven wheels 17 are respectively installed on the two ends of the rotating rod 22, and the transmission belt 18 connects the driving wheel 16 and the driven wheels 17.

[0034] The main body 1 of the device also includes a press wheel 19, which is rotatably mounted at the rear of the seed metering box 31;

[0035] The spacing between the multiple trenching shovels 21, the multiple ball plugs 33, and the multiple seed tubes 15 is all the same.

[0036] Working principle and usage process of this utility model:

[0037] After the device is started, the front wheel 12 is driven to rotate, which in turn drives the frame 11, as well as the trenching structure 2 and the seed metering structure 3 mounted on the frame 11, to move forward. The rotating front wheel 12 drives the drive wheel 16 to rotate, which, through the transmission belt 18, causes the rotating rod 22 connected to the driven wheel 17 to rotate as well, thereby driving the multiple trenching shovels 21 mounted on the rotating rod 22 to rotate, so that the trenching shovels 21 open up multiple trenches in the soil at intervals. At the same time, under the action of gravity and the vibration generated when the frame 11 moves, the wheat seeds in the seed box 14 fall into the seed metering box 31 through the seed inlet tube 15.

[0038] As the front wheel 12 drives the frame 11 to move, the rear wheel 13 mounted on the frame 11 also rotates; the rotating rear wheel 13 drives the cam 36, which is coaxially mounted with the rear wheel 13, to rotate as well; the rotating cam 36 drives the pulley 35, which is in contact with the cam 36, to slide along the circumferential side wall of the cam 36.

[0039] As pulley 35 gradually slides along the circumferential sidewall of cam 36 with a smaller radius, connecting rod 34 connected to pulley 35 moves downward toward the seed outlet 311, thereby driving ball plug 33 to seal the seed outlet 311. At this time, wheat seeds cannot fall from the seed outlet 311. At the same time, anti-blocking column 37 connected to ball plug 33 also moves downward in seed discharging tube 32. In this way, the blockage in seed discharging tube 32 is pushed out by the downward-moving anti-blocking column 37, preventing subsequent wheat seeds from being unable to be discharged from the blocked seed discharging tube 32 into the furrow, thus ensuring wheat yield.

[0040] As the pulley 35 gradually slides along the circumferential sidewall of the cam 36 with a larger radius, the connecting rod 34 connected to the pulley 35 moves away from the seed outlet 311, thereby driving the ball plug 33 away from the seed outlet 311. In this way, the wheat seeds in the seed box 31 fall into multiple furrows with the same spacing through the seed outlet 311 and the seed pipe 32. Finally, as the frame 11 continues to move forward, it drives the press wheel 19 to rotate. The rotating press wheel 19 compacts the soil after sowing, ensuring that the wheat seeds and soil are in full contact.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
