Detailed Implementation
[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0034] Example 1
[0035] like Figs. 1-3 As shown, this embodiment provides a buffer central section, including a swing seat 11 horizontally arranged in the front-rear direction. The front end of the swing seat 11 has a rotating connecting part 111 that runs vertically through it. A first hinge seat 12 is provided on one side of the swing seat 11, and a hinge member 13 is installed at the front end of the other side of the swing seat 11. The hinge member 13 has a second hinge seat 131, and a shock-absorbing component 14 is provided between the hinge member 13 and the swing seat 11. By providing a shock-absorbing component at the position between the hinge member and the swing seat, the hinge member and the swing seat have buffering performance. For the entire buffer central section, the rotating connecting part, the hinge member, and the first hinge seat all constitute connection points, that is, the central buffer section has multiple connection points.
[0036] In this embodiment, there are two first hinge seats, and the two first junction seats are located at both ends of the corresponding side of the swing seat.
[0037] The rotating connection part 111 is a rotating shaft or a tubular shaft, so that the swing seat can be connected with the balance frame through the rotating connection part, and both ends of the rotating connection part protrude from the upper and lower ends of the swing seat.
[0038] The swing seat 11 is hollow, and an opening 112 is arranged on the side of the front end of the swing seat 11 away from the first hinged seat 12. The hinged part 13 is installed in the swing seat 11 through the damping assembly 14, and the second hinged seat 131 extends out of the swing seat 11 through the opening 112. The structure is simple, and the damping assembly is installed in the swing seat, so that the volume of the entire buffer central section is more compact and small.
[0039] The hinged part 13 further comprises a swing arm 132 arranged in the swing seat 11 in the front-rear direction. The front end of the swing arm 132 is connected with the rotating connection part 111, and the second hinged seat 131 is arranged at the rear end of the swing arm 132. The damping assembly 14 is arranged at the inner rear end of the swing seat 11, which is used to apply a swing buffer force to the swing arm 132. Thus, the hinged part has a certain swing space in the swing seat, and the damping assembly provides a buffer function when the hinged part swings. Thus, the entire buffer central section also has a certain buffer function. In the embodiment, the rotating connection part penetrates the interior of the swing seat, so that the rotating connection part can also be used for swing arm rotating installation (the swing point of the swing arm is the rotating connection part).
[0040] The opening 112 is provided with a limiting beam 113, both ends of the limiting beam 113 are connected with both sides of the opening 112, and the length direction of the limiting beam 113 is perpendicular to the length direction of the swing arm 132. The swing arm 132 can swing outward in the swing seat 11 to abut against the limiting beam 113, so that the limiting beam can limit the outward swing stroke of the hinged part. In the embodiment, the side of the swing seat away from the first hinged seat can also be completely open, and the limiting beam can be arranged at intervals. The second hinged seat is located between the two limiting beams. The first hinged seat and the second hinged seat are both U-shaped, and the notches of the first hinged seat and the second hinged seat are away from each other. The inner notch of the first hinged seat is vertically through, and the inner notch of the second hinged seat is front-rear through.
[0041] The shock absorption component 14 described in the above technical solution includes two elastic elements 141. One elastic element 141 is disposed on the inner wall of the swing seat 11 on the side opposite to the opening 112, and the other elastic element 141 is disposed on the side of the limiting beam 113 facing the inside of the swing seat 11. The swing arm 132 swings between the two elastic elements 141. It has a simple structure, good buffering performance, and good noise reduction. Preferably, the elastic element 141 is a rubber pad, which has a simple structure, good durability, and good noise reduction.
[0042] Example 2
[0043] like Figs. 4-6 As shown, this embodiment provides a spray assembly, including a balance frame 2, a spray boom frame 3, a lower connector 4, a first telescopic cylinder 5, a second telescopic cylinder 6, and a buffer central section 1 as described in Embodiment 1. The balance frame 2 is vertically arranged in the left-right direction, and the spray boom frame 3 is vertically arranged on one side of the balance frame 2. The rotating connection part 111 is rotatably connected to the front end of the corresponding side of the balance frame 2 in the horizontal direction. The upper end of the corresponding side of the spray boom frame 3 is rotatably connected to the first hinge seat 12 in the vertical direction. The lower connector 4 is rotatably connected to the lower end of the corresponding side of the balance frame 2 in the horizontal direction. One end of the first telescopic cylinder 5 is connected to the balance frame. The first telescopic cylinder 5 is connected to the second hinge seat 131 at one end, and the second telescopic cylinder 6 is connected to the spray boom frame 3 at one end and to the lower connecting member 4 at the other end. The first telescopic cylinder 5 extends and retracts to drive the spray boom frame 3 to rotate back and forth relative to the balance frame 2, and the second telescopic cylinder 6 extends and retracts to drive the spray boom frame 3 to rotate up and down relative to the balance frame 2. The structure is simple and allows the spray boom frame to be adjusted in multiple degrees of freedom on the balance frame. In particular, the central buffer section can provide a certain buffering effect when the first telescopic cylinder extends and retracts, which makes it stable and durable.
[0044] In the above technical solution, two of each of the spray boom mount 3, buffer central section 1, lower connecting piece 4, first telescopic cylinder 5 and second telescopic cylinder 6 are provided and correspond one-to-one. The two spray boom mounts 3 are respectively installed on both sides of the balance frame 2 through the corresponding buffer central section 1, lower connecting piece 4, first telescopic cylinder 5 and second telescopic cylinder 6. In this way, the two spray booms are mounted on both sides of the balance frame, thereby making the balance of the entire spray assembly better and the working width wider.
[0045] In this embodiment, both the first telescopic cylinder and the second telescopic cylinder can be hydraulic cylinders, telescopic pneumatic cylinders, or telescopic electric cylinders. Preferably, both the first telescopic cylinder and the second telescopic cylinder are hydraulic cylinders.
[0046] The first telescopic cylinder and the second telescopic cylinder are provided with joint bearings at both ends, so that the two ends of the first telescopic cylinder are rotatably connected with the balance frame and the second hinge seat respectively, and the two ends of the second telescopic cylinder are rotatably connected with the spray rod frame and the lower connecting piece respectively.
