Description

Technical Field

[0001] The utility model relates to the technical field of tractor towing, in particular to a towing seat. Background Art

[0002] The towing seat is a key component for connecting a tractor and a towing device (such as an agricultural implement, a hopper, etc.), ensuring that the two can be firmly connected together for joint operation. At the same time, when the tractor is working, the towing seat can transmit the power of the tractor to the towing device so that it can work properly. Moreover, the towing seat also needs to support the weight of the towing device and provide necessary support and stability during the operation process.

[0003] In Figures 4 - 6 In the traditional towing frame 8 shown in, the oil cylinder fixing seat 81 and the suspension lower pull rod fixing seat 82 are respectively arranged on the transmission case 1 and the suspension frame 2, and the front-back distance between the two is relatively large, resulting in a relatively low suspension lifting height of the towing frame 8 for the towing device, and when the suspension lower pull rod is stressed relatively large, it is easy to damage the transmission case. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a towing seat, which adds an external fixing seat and centrally installs the oil cylinder fixing shaft and the suspension lower pull rod fixing shaft on the fixing seat, solves the problem of low suspension lifting height of the towing device, and prevents the transmission case from being damaged.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A towing seat includes a suspension frame fixed to the front end of a transmission case. Fixing seats are arranged on both sides of the suspension frame. Oil cylinder fixing holes and suspension lower pull rod fixing holes are arranged vertically on the fixing seats. A reinforcing plate is jointly installed between the lower end of the suspension frame and the transmission case.

[0007] The following is a further optimization of the above technical solution of the utility model:

[0008] The suspension frame includes a vertical plate, the rear wall of the vertical plate is fixed to the front end of the transmission case, side plates are vertically arranged on both sides of the vertical plate, the side plates are perpendicular to the vertical plate, the rear ends of the side plates are fixedly installed together with the vertical plate, and a connecting block is jointly fixed between the lower ends of the two side plates and the vertical plate.

[0009] Further optimization: One end of the reinforcing plate is fixedly installed at the lower end of the side plate, and the other end of the reinforcing plate is installed at the bottom of the transmission case by means of threaded connection.

[0010] Further optimization: The fixed seat includes a fixed inner plate fixed to the outer wall of the side plate. A fixed outer plate is arranged outside the fixed inner plate. Both the fixed inner plate and the fixed outer plate are arranged parallel to the side plate. The fixed outer plate is fixedly installed with the fixed inner plate through a connecting plate, and the connecting plate is arranged parallel to the vertical plate.

[0011] Further optimization: The oil cylinder fixing hole is penetrated through the side plate, the fixed inner plate and the fixed outer plate.

[0012] Further optimization: The suspension pull-down rod fixing hole is penetrated through the side plate, the fixed inner plate and the fixed outer plate.

[0013] The utility model adopts the above technical solutions and has the following beneficial effects:

[0014] 1. The structure of the utility model is ingeniously conceived and reasonable. Fixed seats are added on both sides of the suspension frame to open the oil cylinder fixing hole and the suspension pull-down rod fixing hole, realizing the fixation of both ends of the suspension pull-down rod and the oil cylinder, and increasing the reliability of the fixation.

[0015] 2. Move the suspension pull-down rod fixing hole backward to reduce the distance between the suspension pull-down rod and the oil cylinder fixing position, so that the suspension pull-down rod can be shortened while the oil cylinder remains unchanged, thereby effectively increasing the lifting height of the tractor for the trailed equipment.

[0016] 3. Reinforcing plates are added at the bottom to realize the multi-point fixation of the transmission case and the suspension frame, avoiding the situation that the transmission case is damaged due to stress concentration between the suspension frame and the transmission case.

[0017] The following further illustrates the utility model with reference to the drawings and embodiments. Description of the Drawings

Fixed seats 3 are provided on both sides of the suspension bracket 2. Oil cylinder fixing holes 4 and suspension lower pull rod fixing holes 5 are arranged vertically on the fixed seats 3. A reinforcing plate 6 is commonly installed between the lower end of the suspension bracket 2 and the transmission box 1

[0028] In this embodiment, an oil cylinder fixing shaft for fixing the oil cylinder can be installed in the oil cylinder fixing hole 4

[0029] A suspension lower pull rod fixing shaft for fixing the suspension lower pull rod on a tractor can be installed in the suspension lower pull rod fixing hole 5

[0030] In this embodiment, fixed seats 3 are added on both sides of the suspension bracket 2, and oil cylinder fixing holes 4 and suspension lower pull rod fixing holes 5 are provided on both sides, realizing the two-end fixation of the lower suspension point, thereby improving the connection stability

[0031] In this embodiment, the oil cylinder fixing hole 4 and the suspension lower pull rod fixing hole 5 are centrally arranged, and the installation position of the suspension lower pull rod is moved backward, realizing the reduction of the distance between the fixing positions of the oil cylinder and the suspension lower pull rod

[0032] Therefore, when the oil cylinder remains unchanged, the length of the suspension lower pull rod can be shortened, thereby increasing the lifting height of the trailer equipment

[0033] Moreover, the fixed position of the hanging pull rod is also changed, avoiding the situation that the transmission box 1 is damaged when the hanging pull rod is stressed during lifting. At the same time, the strength of the fixed shaft of the pull rod can be effectively improved, ensuring the safety and stability of the use of the present utility model.

[0035] As Figure 3 As shown, one end of the reinforcing plate 6 is fixedly installed at the lower end of the side plate 22, and the other end of the reinforcing plate 6 is installed at the bottom of the transmission box 1 by means of threaded connection.

[0036] In this embodiment, a pair of waist holes 61 are provided at the other end of the reinforcing plate 6, fixing screw holes are provided at the bottom of the transmission box 1, the positions of the fixing screw holes correspond to the positions of the waist holes 61, and the waist holes 61 are fixedly connected to the fixing screw holes through fastening screws.

[0037] In this embodiment, the setting of the reinforcing plate 6 increases the traction strength of the transmission box 1 on the suspension bracket 2, improves the reliability of the suspension bracket 2, and thus avoids the situation that the suspension bracket 2 is offset or even broken due to excessive stress on the suspension bracket 2.

[0038] The fixed seat 3 includes a fixed inner plate 31 fixed to the outer wall of the side plate 22, a fixed outer plate 32 is arranged outside the fixed inner plate 31, both the fixed inner plate 31 and the fixed outer plate 32 are arranged in parallel with the side plate 22, the fixed outer plate 32 is fixedly installed with the fixed inner plate 31 through a connecting plate 33, and the connecting plate 33 is arranged in parallel with the vertical plate 21.

[0039] The oil cylinder fixing hole 4 penetrates through the side plate 22, the fixed inner plate 31 and the fixed outer plate 32.

[0040] The hanging pull rod fixing hole 5 penetrates through the side plate 22, the fixed inner plate 31 and the fixed outer plate 32.
