Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture, and particularly relates to a seeding machine device. Background Art

[0002] With the development of science and technology, although machines cannot completely replace manual labor of farmers, they have greatly reduced the labor intensity of people and improved work efficiency. A seeding machine is a main tool for agricultural production and has been widely used in the agricultural seeding process.

[0003] Currently, the patent with the patent number CN202011103144.1 discloses an operation method of an integrated automatic seeding mechanism, which uses universal wheels as the traveling structure of the seeding mechanism. The universal wheels have the characteristic of flexibility and can rotate freely in the horizontal and vertical directions.

[0004] The prior art has the following deficiencies:

[0005] Since universal wheels are used as the traveling structure, when the seeding machine sows seeds, it is easy to deviate from the track, resulting in that each nest of seeds sown by the seeding machine is not on the same straight line, the seeding is not standardized, and the seeding efficiency is reduced, which affects the growth of crops. Content of the Utility Model

[0006] In view of this, the utility model designs a seeding machine device to solve the problem of track deviation that occurs when universal wheels are used as the traveling structure in the prior art, which ultimately leads to the problem that each nest of seeds sown is not on the same straight line and the seeding is not standardized, resulting in a decrease in seeding efficiency.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A seeding machine device includes a main frame. A first wheel frame is arranged on one side of the main frame. An installation frame is rotatably connected to the first wheel frame, and a first traveling wheel is rotatably connected to the installation frame. It further includes a positioning component for fixing the installation frame.

[0009] In this technical solution, it should be noted that the main frame is a rectangular plate structure. The first wheel frame is fixed to the main frame by screws. The mounting frame is an inverted L-shaped structure, and its top plate is rotatably connected to the first wheel frame through a rotating shaft. This rotating shaft is vertically arranged, enabling the first wheel frame to rotate horizontally. The first traveling wheel is located below the top plate of the mounting frame and is rotatably connected to the side plate on one side of the mounting frame through a drive shaft. This drive shaft is horizontally arranged, enabling the first traveling wheel to rotate vertically. That is, by setting the rotating shaft and the drive shaft, the first traveling wheel has the structure of a universal wheel and can freely rotate in the horizontal and vertical directions. When the seeder is not sowing, the operator can flexibly control the traveling direction of the seeder through this universal structure, which is convenient for transportation. Secondly, in this solution, a positioning component is provided. When the seeder sows, the mounting frame is fixed through the positioning component to prevent the first traveling wheel from rotating horizontally, making the whole vehicle move more stably in a straight line during sowing and reducing the probability of deviating from the track. It should be further emphasized that a sowing structure is provided on the main frame. The sowing structure adopts existing technology and will not be elaborated here. Secondly, the number of the first traveling wheels is one or more. To sum up, through the traveling wheels, the first wheel frame and the mounting frame provided in the present utility model, the traveling wheel has a universal wheel mechanism. The operator can flexibly control the traveling direction of the seeder through this universal structure, which is convenient for the transportation of the seeder. And through the provided positioning component, the mounting frame can be fixed to prevent the first traveling wheel from rotating horizontally, making the whole vehicle move more stably in a straight line and reducing the probability of deviating from the track. That is, the first traveling wheel can flexibly switch between the universal wheel state and the fixed wheel state through the use of the positioning component, which is convenient for operation.

[0010] Preferably, the positioning component includes a first connecting member and a second connecting member. The first connecting member is provided on the first wheel frame, the second connecting member is provided on the mounting frame, and the first connecting member and the second connecting member are detachably connected. The first connecting member includes a positioning plate provided on the first wheel frame. The positioning plate is provided with a first positioning hole. The second connecting member includes a second positioning hole provided on the mounting frame. The first positioning hole and the second positioning hole are opposite to each other, and the first positioning hole and the second positioning hole cooperate with a positioning post.

[0011] In this technical solution, it should be noted that the first positioning hole and the second positioning hole can be of a threaded hole structure, and the positioning post can be of a bolt structure. When the seeder sows, the mounting frame is fixed by screwing the bolt into the first positioning hole and the second positioning hole to prevent it from rotating horizontally.

[0012] Preferably, the positioning plate is of an L-shaped structure.

[0013] In this technical solution, it should be noted that the positioning plate is of an L-shaped structure, which has two long sides and a short side that are perpendicular to each other. The long side is vertically arranged and fixed to the first wheel frame by two screws. The first positioning hole is provided on the short side of the positioning plate. In this solution, the first positioning hole and the second positioning hole are aligned vertically.

[0014] Preferably, a second wheel frame spaced from the first wheel frame is further provided on one side of the main frame, and a second traveling wheel rotatably connected thereto is provided on the second wheel frame.

[0015] In this technical solution, it should be noted that the second traveling wheel is parallel to the first traveling wheel and is located on the same side of the main frame. By providing the two traveling wheels, the stability of the main frame during operation can be increased.

[0016] Preferably, a soil wheel frame is provided on the other side of the main frame, and a soil pressing wheel is rotatably connected to the soil wheel frame.

[0017] In this technical solution, it should be noted that the soil wheel frame is installed on the main frame by screws. The soil wheel is used to press the soil after sowing. The soil pressing wheel is cylindrical and is located on the other side of the main frame away from the first traveling wheel and the second traveling wheel, so that the traveling wheels and the soil wheel cooperate to support the left and right sides of the main frame.

[0018] Preferably, both the first traveling wheel and the second traveling wheel are electric wheels, and a power supply box for supplying power to the first traveling wheel and the second traveling wheel is provided on the main frame.

[0019] In this technical solution, it should be noted that the first traveling wheel and the second traveling wheel are driven by motors. A controller can be provided on the main frame or a remote controller can be provided externally. The operation of the first traveling wheel and the second traveling wheel is controlled by the controller or the remote controller to achieve intelligent operation. In addition, it is worth mentioning that since the main frame still needs to have a steering function during sowing for some special terrains, the torque vector control of the two traveling wheels is realized through the controller or the remote controller, and then the sowing machine is steered by the differential steering between the two traveling wheels.

[0020] Preferably, a reinforcing plate is provided on the power supply box, and the reinforcing plate connects the power supply box and the main frame.

[0021] In this technical solution, it should be noted that the reinforcing plate is of a right-angled triangle structure and is made of steel. It connects the power supply box and the main frame to improve the stability of the power supply box.

In addition, the storage bin has a feeding port, and the valve can be an electric valve. Control buttons can be set on the main frame or at a remote end to control the opening and closing of the valve.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0025] 1. In the present utility model, through the arranged traveling wheels, the first wheel frame and the mounting frame, the traveling wheels have a universal wheel mechanism. The staff can flexibly control the traveling direction of the seeder through this universal structure, which is convenient for the transportation of the seeder. And through the arranged positioning components, the mounting frame can be fixed to prevent the first traveling wheel from rotating laterally, making the whole vehicle move more stably in a straight line during seeding and reducing the probability of deviating from the track. That is, the first traveling wheel can be flexibly switched between the universal wheel state and the fixed wheel state through the use of the positioning components, which is convenient for the staff to operate.

[0026] 2. In the present utility model, the first traveling wheel and the second traveling wheel are driven by a motor. A controller can be set on the main frame or a remote controller can be set externally to control the operation of the first traveling wheel and the second traveling wheel through the controller or the remote controller, realizing intelligent operation.

[0027] 3. In the present utility model, steering can be achieved by controlling the differential speed of the first traveling wheel and the second traveling wheel. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the soil wheel carrier 80 is installed on the main frame 10 by screws. The soil pressing wheel 81 is used to press the soil after sowing. The soil pressing wheel 80 is cylindrical and is located on the other side of the main frame 10 away from the first traveling wheel 40 and the second traveling wheel 50, so that the traveling wheels and the soil pressing wheel cooperate to support the left and right sides of the main frame 10.

[0051] Embodiment 4

[0052] As Figure 1 shown, this embodiment is substantially the same as the above embodiment. The difference is that both the first traveling wheel 40 and the second traveling wheel 50 are electric wheels, and a power supply box 70 for supplying power to the first traveling wheel 40 and the second traveling wheel 50 is provided on the main frame 10.

[0054] Embodiment 5

[0055] As Figure 2 shown, this embodiment is substantially the same as the above embodiment.

That is, the first walking wheel 40 forms a universal wheel structure at this time, which is convenient for the staff to transport the seeder;

[0058] When the seeder is sowing, the positioning post is inserted into the first positioning hole 91 and the second positioning hole 92. At this time, the mounting frame 30 is fixed. At this time, the first walking wheel 40 can only rotate on its own axis and can travel stably in a straight line. Then, the motors on the first walking wheel 40 and the second walking wheel 50 are started through an external remote control or the controller on the main frame 10 to drive the main frame 10 to travel. During the traveling process, the opening and closing of the valve in the seeding system are controlled through an external button to realize the falling of seeds, and the soil pressing wheel 81 located at the rear end of the main frame 10 then compacts the soil;

[0059] In addition, during the seeding process, the steering can be carried out by controlling the differential speed of the first walking wheel 40 and the second walking wheel 50.
