Description

Technical Field

[0001] This utility model belongs to the field of sowing technology, and specifically relates to a folding sowing device. Background Technology

[0002] A folding seeder is an agricultural machine with an adjustable sowing width. In transport mode, it can fold up part of its structure to reduce its overall width, making it easier to transport on roads and pass through narrow areas; in operating mode, it can be unfolded to a larger sowing width, improving sowing efficiency.

[0003] The seeder is moved by a tractor. When connecting the tractor and seeder, multiple alignments are required to connect the seeder's suspension point with the tractor's tie rod point. However, current technology lacks a mechanism for adjusting the height of the seeder's suspension point, resulting in poor applicability to different tractor models (different tractors have different heights). Furthermore, the need for multiple alignments for connection (even for the same tractor model, differences in tire pressure and tire wear can cause slight variations in the tie rod point height) is time-consuming. Therefore, this paper proposes a technical solution to address the problems of the lack of a mechanism for adjusting the seeder's suspension point height, poor applicability to different tractor models, the need for multiple alignments for connection, and the time-consuming nature of current technology. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a folding seeding device, which aims to solve the problems of the lack of a mechanism for adjusting the height of the suspension point of the seeder, poor applicability to different models of tractors, the need for multiple alignments before connection, and the time-consuming process.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a folding sowing device, comprising a main body, a main connecting rod mounted at the lower center of the main body surface, an adjusting component mounted at the end of the main connecting rod furthest from the main body, an mounting plate mounted at the end of the main connecting rod furthest from the main body, a first hydraulic cylinder mounted on the mounting plate, and a support plate mounted at the lower end of the first hydraulic cylinder. Thanks to the adjusting component, the height of the sowing machine's suspension point is adjustable, facilitating connection to different tractor models and improving practicality. Furthermore, when the tie rod heights of the same tractor differ, the adjusting plate can easily enter the tie rod point, eliminating the need for multiple alignments and reducing time. Simultaneously, the first hydraulic cylinder, mounting plate, and support plate provide convenient support for the main body, increasing its stability, while maintaining the overall horizontal level of the adjusting component, thus facilitating subsequent connection steps.

[0008] Furthermore, the mounting plate is L-shaped, and the first hydraulic cylinder passes through the main connecting rod.

[0009] Furthermore, a lower beam is installed at the bottom of the main body, and lifting cylinders are installed at both ends of the main body. Thanks to the setting of the lifting cylinders, it is convenient to fold the folding beam, which solves the problem of ultra-wide sowing and ultra-wide road transportation of hanging machines. The operation is simple and the folding and lifting are smooth.

[0010] Furthermore, a lower lifting link is installed at the end of the lifting cylinder away from the main body, and the lower lifting link is connected to a folding beam.

[0011] Furthermore, an upper connecting rod is installed on the upper end of the folding beam near the lower lifting connecting rod.

[0012] Furthermore, a tensioning wheel is installed at the upper end of the main body, an upper beam is installed at the upper end inside the main body, and a fan frame is installed at the upper part inside the main body.

[0013] Furthermore, the adjustment component includes a side plate, which is fixedly installed at the end of the main connecting rod away from the main body. A limit plate is installed at the end of the side plate away from the main connecting rod. The limit plate is slidably connected to a lifting frame. A sliding groove is provided in the middle of the lifting frame, and the sliding groove is adapted to the limit plate.

[0014] Furthermore, a connecting plate is installed in the middle of the side of the lifting frame, and a second hydraulic cylinder is connected to the upper surface of the connecting plate. The second hydraulic cylinder is installed on the side plate. Two sets of clamping plates are symmetrically installed on the side of the lifting frame away from the connecting plate, and two sets of symmetrically distributed threaded holes are opened in the clamping plates.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model, through the arrangement of a first hydraulic cylinder, mounting plate, and support plate, facilitates the support of the main body, increases the stability of the main body, and maintains the overall horizontal level of the adjustment components, thereby facilitating the next step of connection. Activating the first hydraulic cylinder drives the support plate to move upward, releasing the normal support of the main body.

[0018] The lifting cylinder facilitates the folding of the main beam, solving the problem of ultra-wide seeding and road transport of extra-wide structures. The operation is simple, and the folding and lifting are smooth. Activating the lifting cylinder moves the lower lifting link upward, which in turn moves the folding beam upward, which in turn folds the upper link, thus reducing the width.

[0019] By adjusting the component settings, the height of the seeder's suspension point can be adjusted, facilitating connection to different tractor models and improving practicality. Furthermore, when the tie rod heights of the same tractor differ, it allows for easy adjustment of the clamping plate to enter the tie rod point, eliminating the need for multiple alignments and reducing time. The second hydraulic cylinder activates, moving the clamping plate up and down. Once the clamping plate matches the tractor's tie rod height, the second hydraulic cylinder is deactivated, and a bolt is used to thread a connection between the tie rod point and the clamping plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a folding seeding device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3 As shown, the system includes a main body 1. A main connecting rod 11 is installed at the lower middle of the surface of the main body 1. An adjusting component 2 is installed at the end of the main connecting rod 11 away from the main body 1. An mounting plate 12 is installed at the end of the main connecting rod 11 away from the main body 1. A first hydraulic cylinder 13 is installed on the mounting plate 12. A support plate 14 is installed at the lower end of the first hydraulic cylinder 13. The mounting plate 12 is L-shaped. The first hydraulic cylinder 13 passes through the main connecting rod 11. A lower beam 9 is installed at the lower part of the main body 1. Lifting cylinders 3 are installed at both ends of the main body 1. A lifting lower connecting rod 4 is installed at the end of the lifting cylinder 3 away from the main body 1. The lifting lower connecting rod 4 is connected to a folding beam 10. The folding beam 10 has a support plate 14 on the side near the lifting lower connecting rod 4. The upper connecting rod 5 is installed at the end, the tension wheel 7 is installed at the upper end of the main body 1, the upper beam 8 is installed at the upper end of the interior of the main body 1, and the fan frame 6 is installed at the upper part of the interior of the main body 1. When it is necessary to change the width of the folding seeding device (for example, to reduce the width), the lifting cylinder 3 is activated to drive the lower lifting connecting rod 4 to move upward. The upward movement of the lower lifting connecting rod 4 drives the folding beam 10 to fold upward. The upward folding of the folding beam 10 drives the upper connecting rod 5 to fold, thereby reducing the width. When it is necessary to work, it is connected to the tractor through the adjusting component 2 and the main connecting rod 11. After the connection is completed, the first hydraulic cylinder 13 is activated to drive the support plate 14 to move upward, thereby causing the support plate 14 to lift off the ground.

[0028] Reference Figure 1 , Figure 2 , Figure 4As shown, the adjusting assembly 2 includes a side plate 201, which is fixedly installed on the end of the main connecting rod 11 away from the main body 1. A limit plate 202 is installed on the end of the side plate 201 away from the main connecting rod 11. A lifting frame 204 is slidably connected to the limit plate 202. A slide groove 205 is provided in the middle of the interior of the lifting frame 204, which is adapted to the limit plate 202. A connecting plate 206 is installed in the middle of the side of the lifting frame 204. A second hydraulic cylinder 203 is connected to the upper surface of the connecting plate 206. The second hydraulic cylinder 203 is installed on the side plate 201. Two sets of clamping plates 207 are symmetrically installed on the side of the lowering frame 204 away from the connecting plate 206. Two sets of symmetrically distributed threaded holes 208 are opened in the clamping plates 207. The second hydraulic cylinder 203 is started to drive the connecting plate 206 to move up and down. The up and down movement of the connecting plate 206 drives the lifting frame 204 to move up and down along the limit plate 202. The up and down movement of the lifting frame 204 drives the clamping plates 207 to move up and down. When the clamping plate 207 is matched with the height of the tractor's tie rod point, the second hydraulic cylinder 203 is closed. At this time, the tie rod point and the clamping plate 207 are threadedly connected by bolts.

[0029] Working principle: When it is necessary to change the width of the folding sowing device (e.g., reduce the width), the lifting cylinder 3 is activated to drive the lower lifting link 4 to move upward. The upward movement of the lower lifting link 4 drives the folding beam 10 to fold upward. The upward folding of the folding beam 10 drives the upper link 5 to fold, thereby reducing the width. When it is necessary to work, it is connected to the tractor through the adjusting component 2 and the main connecting rod 11. After the connection is completed, the first hydraulic cylinder 13 is activated to drive the support plate 14 to move upward, thereby lifting the support plate 14 off the ground. The setting of the first hydraulic cylinder 13, the mounting plate 12, and the support plate 14 facilitates the support of the main body 1, increases the stability of the main body 1, and maintains the overall horizontality of the adjusting component 2, thus facilitating the next connection. The setting of the lifting cylinder 3 facilitates the folding beam 10 to fold, solving the problem of ultra-wide sowing and ultra-wide road transport of trailers. The operation is simple and the folding and lifting are smooth.

[0030] The specific working principle of the adjustment component 2 is as follows: the second hydraulic cylinder 203 is activated, causing the connecting plate 206 to move up and down. The up and down movement of the connecting plate 206 causes the lifting frame 204 to move up and down along the limit plate 202. The up and down movement of the lifting frame 204 causes the clamping plate 207 to move up and down. When the clamping plate 207 is at the same height as the tractor's tie rod point, the second hydraulic cylinder 203 is deactivated. At this time, the tie rod point and the clamping plate 207 are threadedly connected by bolts. Through the setting of the adjustment component 2, the function of adjusting the height of the seeder's suspension point is realized, which facilitates the connection of different models of tractors, improves practicality, and makes it easy to adjust the clamping plate 207 to enter the tie rod point when the tie rod point height of the same tractor is different, without the need for multiple alignments to connect, thus saving a lot of time.
