Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a single-wheel transmission mechanism adapted to a no-till planter. Background Technology

[0002] No-till seeders are advanced agricultural seeding machines that can sow seeds directly on land without traditional tillage. They offer advantages such as soil conservation, reduced water and soil erosion, and lower costs. No-till seeders are suitable for sowing a variety of crops, including corn, wheat, soybeans, and sorghum. They are particularly widely used in areas where conservation tillage techniques are well-established, such as parts of Northeast and North China, as well as some arid and semi-arid regions. They are suitable not only for large-scale farmland operations in plains but also for small plots of farmland in hilly and mountainous terrain.

[0003] Most no-till precision seeders on the market are driven by dual rubber-tired ground wheels or dual rubber-tired ground wheels driving friction wheels. These transmissions share a common problem: the transmission system is too complex and heavy. When carrying the load, the tractor needs to have a large lifting force, which increases the requirements for the matching agricultural machinery. Tractors with large lifting forces also have greater traction power and higher prices, increasing farmers' production input. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a single-wheel drive mechanism adapted to no-till planters, aiming to improve the problem in the prior art that the tractor needs to have a large lifting force when carrying operations, which increases the requirements for the matching agricultural machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a single ground wheel transmission mechanism adapted to a no-till planter, comprising a ground wheel assembly, a drive gearbox mounted on the right side of the ground wheel assembly, a gearbox assembly mounted on the right side of the drive gearbox, a drive shaft and connecting parts mounted on the right side of the gearbox assembly, a ground wheel bracket provided on the outer wall of the ground wheel assembly, a ground wheel fixing seat mounted at the bottom of the ground wheel bracket, a drive sprocket rotatably connected to the inner left end of the ground wheel bracket, a driven sprocket rotatably connected to the inner right end of the ground wheel bracket, the drive sprocket being connected to the driven sprocket via a chain, and a ground wheel fixedly connected to the outer side of the drive sprocket.

[0006] As a further description of the above technical solution:

[0007] The gearbox assembly includes a housing, with a drive sprocket set rotatably connected to the upper inner side of the housing, and a driven sprocket set rotatably connected to the lower inner side of the gearbox assembly. The drive sprocket set is connected to the driven sprocket set via a chain.

[0008] As a further description of the above technical solution:

[0009] A chain tensioning mechanism is installed on the outer side of the second chain.

[0010] As a further description of the above technical solution:

[0011] The outer side of the box is fitted with a cover plate.

[0012] As a further description of the above technical solution:

[0013] A coupling sleeve is installed at the front end of the driven sprocket assembly.

[0014] As a further description of the above technical solution:

[0015] An output shaft is installed on the rear side of the driven sprocket assembly.

[0016] As a further description of the above technical solution:

[0017] An input shaft is installed at the rear end of the drive sprocket assembly.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, a single ground wheel transmission mechanism is installed on the seeder by bolts and connected to the corresponding drive shaft to ensure that the ground wheel makes full contact with the ground during operation. Subsequently, a tractor can be driven to pull the seeder to perform the sowing task. The mechanism has a simple structure, is lightweight, has high reliability, and can be effectively adapted to existing no-till seeders, replacing the original dual ground wheel transmission system, thereby reducing the requirements for supporting agricultural machinery.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a single ground wheel transmission mechanism adapted to a no-till planter, comprising a ground wheel assembly 1, a drive gearbox 4 mounted on the right side of the ground wheel assembly 1, a gearbox assembly 2 mounted on the right side of the drive gearbox 4, a drive shaft and connecting parts 3 mounted on the right side of the gearbox assembly 2, a ground wheel bracket 9 provided on the outer wall of the ground wheel assembly 1, a ground wheel fixing seat 8 mounted on the bottom of the ground wheel bracket 9, a drive sprocket 5 rotatably connected to the inner left end of the ground wheel bracket 9, a driven sprocket 7 rotatably connected to the inner right end of the ground wheel bracket 9, the drive sprocket 5 being connected to the driven sprocket 7 via a chain 6, and a ground wheel 10 fixedly connected to the outer side of the drive sprocket 5.

[0027] Specifically, the ground wheel 10 rotates due to friction with the ground under the tractor's traction. This rotation, via a chain and sprocket, drives the input drive shaft, which in turn drives the gearbox 4, which in turn drives the seed metering device for sowing. The entire ground wheel assembly is bolted to the main beam of the machine frame, securing the ground wheel mounting base 8. Under the tractor's traction, the ground wheel 10 begins to rotate, which in turn drives the chain via the drive sprocket, transmitting power to the driven sprocket 7. The driven sprocket 7 then drives the input drive shaft, which in turn drives the sprocket inside the gearbox.

[0028] Reference Figure 1 , Figure 2 and Figure 3The gearbox assembly 2 includes a housing 15. A drive sprocket set 11 is rotatably connected to the upper inner side of the housing 15, and a driven sprocket set 16 is rotatably connected to the lower inner side of the gearbox assembly 2. The drive sprocket set 11 is connected to the driven sprocket set 16 via a chain 12. A chain tensioning mechanism 13 is installed on the outer side of the chain 12. A cover plate 14 is installed on the outer side of the housing 15. A coupling sleeve 19 is installed at the front end of the driven sprocket set 16. An output shaft 18 is installed at the rear side of the driven sprocket set 16. An input shaft 17 is installed at the rear end of the drive sprocket set 11.

[0029] Specifically, the input drive shaft is combined with the input shaft of the gearbox, which drives the drive chain of the active sprocket group 11 under the action of the tensioning mechanism 13, causing the driven sprocket group 16 to drive the output shaft 18 to rotate. The output shaft 18 is connected to the drive shaft on the unit through the coupling sleeve 19, which drives the seed metering device to complete the sowing operation.

[0030] Working principle: The single ground wheel 10 transmission device is assembled onto the seeder with bolts, and the relevant drive shaft is connected so that the ground wheel 10 is in full contact with the ground when the machine is in operation, and the tractor can be driven to pull the seeder for sowing operations;

[0031] The gearbox assembly 2 is a functional component of the system, comprising a gearbox housing, cover plate 14, chain tensioning mechanism, chain, drive sprocket assembly 11, driven sprocket assembly 16, input / output shafts, and coupling sleeves. It is adapted to the single ground wheel 10 transmission system of the no-till seeder. When the tractor carries or tows the seeder, the friction between the ground wheel 10 and the ground generates power, which drives the chain to the sprocket 5, and then through the gearbox. Different transmission ratios of the sprockets are combined to achieve different transmission speeds, ultimately driving the seed metering device for sowing. This system reduces the number of ground wheels 10 in contact with the ground and the number of sprockets in the transmission process compared to previous transmission systems, thus reducing structural weight and potential failure points. Furthermore, the ground wheel 10 is a welded iron structure, which provides a tighter bond with the soil compared to rubber ground wheels 10, reducing slippage and loss of rotation, making the transmission more reliable and the speed change more precise.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
