Description

Technical Field

[0001] This utility model relates to agricultural operating machines, specifically a frame assembly for an agricultural operating machine. Background Technology

[0002] The frame assembly of an agricultural work machine is a structural component used to support and connect the various systems of the agricultural work machine to form a whole.

[0003] Chinese patent document CN210406114U discloses a high-clearance garden tiller, including an engine, a transmission system, a sprocket drive mechanism, a frame, a tracked walking system, a rotary tillage and suspension system, and a driver's seat. Its features include: two sets of rotary tillage and suspension systems suspended on the left and right sides of the frame; the engine mounted at the rear of the frame; and two tracked walking systems respectively located on both sides of the frame. The engine drives the drive wheel of the tracked walking system to rotate via the transmission system and the sprocket drive mechanism. The track of the tracked walking system has a triangular structure, and the drive wheel is located at the apex of the triangular track structure. The driver's seat is fixed to the frame and located above the tracked walking system.

[0004] In this prior art, the operating device of the management unit is located in front of the driver's seat and is directly mounted on the upper part of the frame. This requires the frame to have reserved installation space and an assembly structure, making the frame structure relatively complex. Furthermore, when adjustments to the operating device are needed (such as changing its position), the entire frame assembly, including the main frame, must also be adjusted, resulting in high adjustment costs. Moreover, vibrations generated by the engine and other devices during operation are directly transmitted to the operating device through the frame, affecting the accuracy of the operator's operation. Utility Model Content

[0005] The purpose of this utility model is to provide a frame assembly for an agricultural work machine to solve the problem of poor versatility of the frame assembly of agricultural work machines in the prior art.

[0006] To achieve the above objectives, the basic solution of this utility model provides a frame assembly for an agricultural work machine, including a frame and a protective frame. The protective frame includes a protective part arranged along the horizontal contour of the agricultural work machine, and the protective frame also includes a cantilevered part arranged along the front end of the frame for supporting the agricultural machine's operating device. The protective part and the cantilevered part are statically connected, and the protective part is detachably connected to the frame.

[0007] The beneficial effects of this basic solution are as follows: by setting a protective frame that can be detachably connected to the machine frame, and by setting a cantilever part on the protective frame to support the agricultural machinery operating device, when the agricultural machinery operating device needs to be adjusted, only the protective frame needs to be adjusted, without adjusting the structure of the machine frame. Adjusting the protective frame will greatly reduce the difficulty of operation compared to adjusting the machine frame, thereby improving the versatility of the frame assembly.

[0008] Preferably, the protective frame is inclined, and the cantilevered portion is located below the protective frame. This arrangement lowers the height of the cantilevered portion, which helps to reduce the center of gravity after the agricultural machinery operating device is installed, thus improving structural stability.

[0009] Preferably, the upper end of the protective part is connected to the rear end of the frame, and the lower end of the protective part is connected to the front end of the frame. This arrangement disperses the stress points between the protective part and the frame, thus helping to distribute the forces and improve structural stability.

[0010] Preferably, the protective part is connected to the frame via a shock-absorbing mechanism. With this arrangement, the shock-absorbing mechanism reduces vibration transmission between the protective part and the frame, thereby reducing the transmission of frame vibration to the cantilever part through the protective part. This reduces the impact of frame vibration on the cantilever part, and consequently, helps to reduce the impact of frame vibration on the agricultural machinery operating devices installed at the cantilever part.

[0011] Preferably, the vibration damping mechanism includes a first connecting member, a second connecting member, and a vibration damping column. The first connecting member is connected to the second connecting member via the vibration damping column. The upper end of the vibration damping column abuts against the protective part, and the lower end of the vibration damping column abuts against the frame. The first connecting member is connected to the protective part, and the second connecting member is connected to the frame. This arrangement facilitates the connection and fixation of the vibration damping mechanism to both the frame and the protective part, and effectively reduces vibration transmission between the frame and the protective frame.

[0012] Preferably, the first connector is connected to the middle of the damping column, and the second connector is connected to the circumferential edge of the damping column. This arrangement ensures that the force is transmitted more evenly among the first connector, the damping column, and the second connector, thereby further improving the reliability and service life of the damping mechanism.

[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, this solution only requires adjustment of the protective frame when the frame assembly needs to be adjusted according to the position of the agricultural machinery operating device, without the need to adjust the machine frame, thereby improving the versatility of the frame assembly and reducing the difficulty of operation.

[0014] 2. Compared with the existing technology, this solution sets up a shock absorption mechanism between the protective frame and the machine frame, which reduces the transmission of machine frame vibration to the protective frame, thereby reducing the impact of machine frame vibration on the agricultural machinery operating devices installed on the protective frame.

Detailed Implementation

[0016] As those skilled in the art will know, the "agricultural machinery operating device" in this utility model refers to the general term for various mechanisms that require driver operation, such as steering wheels or steering handles for controlling direction, clutch operating mechanisms, and brake operating mechanisms, in the prior art.

[0017] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame 1, front end 11, protective frame 2, protective part 21, cantilever part 22, shock absorption mechanism 3, first connecting piece 31, shock absorption column 32, second connecting piece 33, and agricultural machinery operating device 4.

[0018] The basic implementation examples are as follows: Figures 1 to 4 As shown: A frame assembly of an agricultural work machine includes a frame 1 and a protective frame 2. The protective frame 2 includes a protective part 21 arranged along the horizontal contour of the agricultural work machine. The protective frame 2 also includes a cantilever part 22 that is suspended along the front end 11 of the frame 1 for supporting the agricultural machine operating device 4. The protective part 21 and the cantilever part 22 are statically connected, and the protective part 21 is detachably connected to the frame 1.

[0019] In this embodiment, the cantilever portion 22 and the protective portion 21 are integrally welded and fixed. Of course, in other embodiments, the cantilever portion 22 and the protective portion 21 can also be integrally formed.

[0020] In this embodiment, the protective frame 2 is inclined, and the cantilever part 22 is located below the protective part 21. This prevents the agricultural machinery operating device 4 from being installed on the cantilever part 22, thus avoiding the problem of the agricultural machinery operating device 4 being too high and causing the center of gravity of the agricultural machine to be too high. The upper end of the protective part 21 is connected to the rear end of the frame 1, and the lower end of the protective part 21 is connected to the front end 11 of the frame 1. Specifically, the protective part 21 is roughly rectangular, with the short side at the upper end of the protective part 21 connected to the frame 1, and the short side at the lower end of the protective part 21 connected to the frame 1.

[0021] In this embodiment, the protective part 21 is connected to the frame 1 via a shock-absorbing mechanism 3. Specifically, the shock-absorbing mechanism 3 includes a first connecting member 31, a second connecting member 33, and a shock-absorbing column 32. The first connecting member 31 is connected to the second connecting member 33 via the shock-absorbing column 32. The upper end of the shock-absorbing column 32 abuts against the protective part 21, and the lower end of the shock-absorbing column 32 abuts against the frame 1. The first connecting member 31 is connected to the protective part 21, and the second connecting member 33 is connected to the frame 1. Preferably, the first connecting member 31 is connected to the middle of the shock-absorbing column 32, and the second connecting member 33 is connected to the circumferential edge of the shock-absorbing column 32. In this embodiment, the shock-absorbing column 32 is generally cylindrical. A radially extending mounting seat is fixedly connected to the lower end of the shock-absorbing column 32, and the mounting seat is connected to the frame 1 via the second connecting member 33. The first connecting member 31 and the shock-absorbing column 32 are coaxially arranged, and the lower end of the first connecting member 31 is detachably connected to the shock-absorbing column 32. Specifically, both the first connector 31 and the second connector 33 are bolts.

[0022] The specific implementation process is as follows: The protective frame 2 is connected to the machine frame 1 through the shock absorption mechanism 3, thereby achieving the connection and fixation between the protective frame 2 and the machine frame 1, and also realizing the shock absorption setting between them. Then, the agricultural machinery operating device 4 is installed on the cantilever part 22 of the protective frame 2, thus realizing the installation and setting of the agricultural machinery operating device 4. Compared with the existing technology, when the frame assembly needs to be adjusted according to the position of the agricultural machinery operating device 4, this solution only requires the adjustment of the protective frame 2, without adjusting the machine frame 1, thereby improving the versatility of the frame assembly and reducing the difficulty of operation; and it reduces the vibration of the machine frame 1 transmitted to the protective frame 2, thereby reducing the impact of the vibration of the machine frame 1 on the agricultural machinery operating device 4 installed on the protective frame 2.

[0023] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
