Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery mobile devices, specifically a self-propelled agricultural machinery device. Background Technology

[0002] Agricultural machinery, or agricultural equipment for short, refers to mechanical equipment used in all aspects of agricultural production, covering operations such as tillage, planting, management, harvesting, processing, storage and transportation. It aims to improve agricultural production efficiency, reduce labor intensity, and promote the large-scale, precision and intelligent development of modern agriculture.

[0003] However, existing agricultural machinery relies on tractors for towing, cannot be self-propelled, cannot complete operations independently, and cannot adapt to rapid relocation during operations. For example, some existing corn silos are over 30 meters long, or there is a certain distance between multiple corn piles. After the corn thresher is towed to the work site by a tractor and detached from the tractor, it still needs to move short distances during operation. At present, this can only be done by pushing or lifting by manpower, requiring multiple people, which is time-consuming and labor-intensive, and cannot achieve continuous operation, greatly reducing agricultural production efficiency. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a self-propelled agricultural machinery device that can drive agricultural machinery to move on its own, thereby improving agricultural production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-propelled agricultural machinery device includes a frame and wheels mounted on the frame. The device comprises a drive gear, a driven gear, a rotary actuator, and a pushing mechanism. The driven gear is mounted on the wheel axle, the pushing mechanism is mounted on the frame, the rotary actuator is mounted on the pushing mechanism, and the drive gear is mounted on the output shaft of the rotary actuator. The pushing mechanism drives the rotary actuator and the drive gear to move, achieving engagement and disengagement between the drive gear and the driven gear. When the drive gear and the driven gear are engaged, the rotary actuator drives the drive gear, the driven gear, and the wheels to rotate, thus enabling the agricultural machinery to self-propelle.

[0007] Furthermore, the driving gear and the driven gear have the same module, and the number of teeth on the driven gear is greater than the number of teeth on the driving gear.

[0008] Furthermore, the rotary actuator is an electric motor, a hydraulic motor, a hydraulic rotary cylinder, a pneumatic motor, or a rack and pinion pneumatic actuator.

[0009] Furthermore, the pushing mechanism is a linear motion mechanism, which achieves linear movement of the load through sliding friction or rolling friction.

[0010] Furthermore, the pushing mechanism includes a lever, a frame, a slide block, a slider, and a rotary actuator frame; the lever is hinged to the frame, the end of the lever is hinged to the slider, the slide block is fixed to the frame, the slider is mounted on the slide block and slidably connected to the slide block, and the rotary actuator frame is fixed to the slider; moving the lever rotates the lever, causing the slider and the rotary actuator frame to slide along the slide block.

[0011] Furthermore, the frame is fixed to the vehicle frame by U-bolts.

[0012] Furthermore, a bushing is provided in the middle of the lever, and the bushing is fitted onto a bolt, which is mounted on the frame.

[0013] Furthermore, the end of the lever is spherical, and the slider has a corresponding spherical groove, with the end of the lever placed in the spherical groove.

[0014] Furthermore, the rotary actuator frame is L-shaped, with one side fixed to the non-load-bearing surface of the slider and the rotary actuator fixed to the other side; the frame is L-shaped, with one side having an elongated hole for connecting to the vehicle frame, and the lever and slider installed on the other side.

[0015] Furthermore, the cross-section of the slider is partly dovetail-shaped and partly rectangular; the slide block is provided with a corresponding groove.

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

[0017] 1. This utility model includes a drive gear, a driven gear, a rotary actuator, and a pushing mechanism. The driven gear is mounted on the wheel axle, the rotary actuator is mounted on the pushing mechanism, and the drive gear is mounted on the output shaft of the rotary actuator. The pushing mechanism drives the rotary actuator and drive gear to move, thus separating the drive gear from the driven gear, allowing the agricultural machinery to be towed by a tractor. Alternatively, the pushing mechanism can also drive the rotary actuator and drive gear to move, meshing the drive gear with the driven gear. The rotary actuator then drives the drive gear, driven gear, and wheel to rotate, enabling the agricultural machinery to move independently. After the agricultural machinery is towed to the work site by a tractor and then disengaged from the tractor, this utility model enables the agricultural machinery to move independently, allowing for short-distance movement during operation, saving work time, reducing labor intensity, ensuring continuous operation, and thus significantly improving agricultural production efficiency.

[0018] 2. The pushing mechanism of this utility model is a linear motion mechanism, which achieves linear movement of the load through sliding friction or rolling friction. The pushing mechanism includes a lever, a frame, a slide, a slider, and a rotary actuator frame. By moving the lever, the rotary actuator frame is driven to slide back and forth along the slide, thereby realizing the engagement and disengagement of the drive gear and the driven gear. The above structure is simple, without complex structural parts, easy to process, install and maintain, sturdy and durable, with a low failure rate, greatly reducing manufacturing and use costs.

[0019] 3. The frame of this utility model is fixed to the vehicle frame with U-bolts, which facilitates installation and disassembly.

[0020] 4. The rotary actuator frame and the machine frame of this utility model are both L-shaped, with a compact layout, strong stability, and convenient installation and maintenance. The L-shape reduces the amount of material used and is suitable for light-duty applications.

[0021] 5. The cross-section of the slider of this utility model is partly dovetail-shaped and partly rectangular. It has high rigidity and load-bearing capacity, high precision and stability, good guiding performance, simple structure, and low cost. Attached Figure Description

[0037] like Figure 1-8 As shown, a self-propelled agricultural machinery device is used in this embodiment for a corn thresher. The walking part of the corn thresher includes a frame 1 and wheels 2 mounted on the frame 1. The walking part of the corn thresher is a tricycle with two wheels at the rear and one wheel at the front. The frame 1 is welded from profiles and bears the weight of the entire vehicle. The front end of the vehicle is equipped with a connecting beam that connects to a tractor for traction and transportation by the tractor.

[0038] This utility model includes a drive gear 3, a driven gear 4, a rotary actuator and a pushing mechanism 6. In this embodiment, the rotary actuator is a motor 5, which is connected to a storage battery and powered by the storage battery.

[0039] like Figure 3-6 As shown, the pushing mechanism 6 is a linear motion mechanism that achieves linear movement of the load through sliding friction or rolling friction. The pushing mechanism 6 includes a lever 61, a frame 62, a slide block 63, a slider 64, and a motor frame 65 (rotary actuator frame). The frame 62 is L-shaped and consists of two mutually perpendicular flat plates. One plate (side) has an elongated hole 66 for connecting to the frame 1. The frame 62 is fixed to the rectangular longitudinal beam of the frame 1 by U-bolts 67 and the elongated hole 66. The frame 62 of this invention is fixed to the frame 1 by U-bolts 67, facilitating installation and disassembly.

[0040] The main body of the lever 61 is a round rod with a handle 68 at one end and a ball at the other end. A bushing 69 is provided in the middle, and the bushing 69 is fitted onto a bolt. The bolt is installed on the top surface of another flat plate (side) of the frame 62. The lever 61 can rotate around the bolt as the pivot.

[0041] The slider 64 has a dovetail-shaped cross-section and a rectangular cross-section, with corresponding grooves on the slide block 63. The two slide blocks 63 are parallel to each other and fixed to the bottom surface of another flat plate (side) of the frame 62. The slider 64 is mounted between the two slide blocks 63 and can move back and forth along the slide blocks 63. The combination of the dovetail and rectangular shapes gives the slider 64 high rigidity and load-bearing capacity, high precision and stability, good guiding properties, simple structure, and low cost.

[0042] The motor frame 65 is L-shaped and consists of two mutually perpendicular flat plates. The top surface of one plate (side) is fixed to the non-load-bearing surface of the slider (bottom surface), and the motor 5 is mounted on the other plate (side).

[0043] Both the motor frame 65 and the frame 62 of this utility model are L-shaped, with a compact layout, strong stability, and convenient installation and maintenance. The L-shape reduces the amount of material used and is suitable for light-duty applications.

[0044] The end of the lever 61 is spherical, and the slider 64 has a corresponding spherical groove 610. The end of the lever 61 is placed in the spherical groove 610. By holding the handle 68 of the lever 61, the lever 61 is rotated, that is, the lever 61 is moved left and right, which causes the slider 64 to move back and forth.

[0045] Driven gear 4 is mounted on the axle of rear wheel 2, and drive gear 3 is mounted on the output shaft of motor 5. Drive gear 3 and driven gear 4 have the same module, and the number of teeth on driven gear 3 is more than twice the number of teeth on drive gear 4. This invention drives the rear wheel to rotate, providing a rear-wheel drive mode, and the vehicle is propelled forward by the rear wheels.

[0046] like Figure 1 As shown, by pulling lever 61, the slider 64 and the drive gear 3 on the motor 5 move forward, and the drive gear 3 engages with the driven gear 4. The motor 5 drives the drive gear 3, driven gear 4, and wheels 2 to rotate, enabling the corn thresher to move independently. After the corn thresher is towed to the work site by a tractor and then detached from the tractor, this invention enables the corn thresher to move independently, allowing for short-distance movement during operation, saving work time, reducing labor intensity, ensuring continuous operation, and thus significantly improving agricultural production efficiency. After the work is completed, as... Figure 2 As shown, by pulling lever 61, the slider 64 and the drive gear 3 on the motor 5 move backward, and the drive gear 3 separates from the driven gear 4, so that the front end of the tricycle can be hooked onto the tractor and towed away from the work site by the tractor.

[0047] This invention enables agricultural machinery to move independently, allowing for short-distance movement during operation, saving time, reducing labor intensity, ensuring continuous operation, and thus significantly improving agricultural production efficiency. The pushing mechanism 6 of this invention is a linear motion mechanism, achieving linear movement of the load through sliding or rolling friction. Its simplified structure, without complex components, facilitates processing, installation, and maintenance. It is robust, durable, and has a low failure rate, greatly reducing manufacturing and operating costs.

[0048] The above description is only a part of the specific embodiments of this utility model. The protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
