Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology, and particularly relates to a spray boom shock-absorbing balance frame, a spray assembly and a sprayer. Background Technology

[0002] For medium to large-sized sprayers, the overall arm span of the spray booms on both rear sides is relatively long when extended. When the road surface is uneven, the swaying of the spray booms is doubled. Therefore, even a slight sway of the vehicle body will cause the spray booms to sway significantly. Thus, it is not advisable to rigidly install the spray booms to the vehicle body, but rather to use a suspended shock-absorbing frame for installation. Although the document CN200997852Y, "Automatic Balancing Suspension Mechanism for Boom Sprayers," discloses a balance frame for floating installation of the spray booms, which can make the spray booms maintain good stability (tend to remain horizontal) even when the vehicle body is bumpy, if the sprayer is on a sloping road surface (the two sides are not at the same height), the spray booms will tend to remain horizontal under the action of the balance frame and their own weight. This can easily cause one side of the spray booms to touch the ground, which will affect its passability. Utility Model Content

[0003] To solve the above-mentioned technical problems, one of the objectives of this utility model is to provide a spray bar shock-absorbing balance frame with a simple structure, good shock absorption performance, and adjustable tilt angle of the movable frame relative to the mounting frame.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A spray boom shock-absorbing and balancing frame includes a mounting frame, a movable frame, a telescopic cylinder, a linkage rod, and a shock-absorbing component. Both the mounting frame and the movable frame are vertically arranged in the left-right direction. The movable frame is located behind the mounting frame and is connected to the mounting frame via the shock-absorbing component. The linkage rod is vertically arranged above the middle of the movable frame, with its upper end movably connected to the upper end of the mounting frame and its lower end movably connected to the middle of the movable frame. The telescopic cylinder is arranged in the left-right direction and is movably mounted on the movable frame, with its telescopic end movably connected to the linkage rod. The telescopic cylinder extends or retracts to drive the movable frame to tilt or return to its original position relative to the mounting frame.

[0005] The beneficial effects of the above technical solution are as follows: by mounting the movable frame on the mounting frame with shock-absorbing components, the movable frame can float relative to the mounting frame under the action of the shock-absorbing components, which has good shock absorption performance. When it is necessary to adjust the tilt angle of the movable frame relative to the mounting frame, it can be done simply by extending or retracting the telescopic cylinder.

[0006] The above technical solution also includes multiple connecting rods, all of which are arranged in the front-to-back direction between the mounting frame and the movable frame, with each connecting rod having its two ends movably connected to the mounting frame and the movable frame, respectively.

[0007] The beneficial effect of the above technical solution is that it makes the floating connection between the mounting frame and the movable frame more reliable.

[0008] In the above technical solution, both the mounting frame and the movable frame are hollow frames. The upper connecting frame protrudes backward from the middle of the upper end of the mounting frame, and the lower connecting frame protrudes backward from the lower end of the middle of the rear side of the movable frame. The linkage rod is vertically arranged behind the movable frame, and the upper end of the linkage rod is movably connected to the upper connecting frame, and the lower end of the linkage rod is movably connected to the lower connecting frame. A first connecting ear is provided in the middle of the linkage rod, and a second connecting ear is provided on one side of the movable frame. The two ends of the telescopic cylinder are movably connected to the first connecting ear and the second connecting ear, respectively.

[0009] The beneficial effect of the above technical solution is that it makes the weight of the entire spray bar shock absorption and balance frame lighter, thereby reducing the load on the shock absorption components.

[0010] The shock absorption assembly described in the above technical solution includes multiple vertically arranged first shock absorbers. The multiple first shock absorbers are all vertically arranged and spaced apart in the left-right direction. The upper end of each first shock absorber is connected to the upper end of the movable frame, and the lower end of each first shock absorber is connected to the mounting frame.

[0011] The beneficial effect of the above technical solution is that it allows the mounting frame to float up and down under the action of multiple first shock absorbers to perform vertical shock absorption.

[0012] In the above technical solution, a mounting beam is provided in the middle of the mounting frame along the left-right direction, and the lower end of the first shock absorber is connected to the mounting beam.

[0013] The beneficial effect of the above technical solution is that it makes it easier to connect the first shock absorber to the mounting bracket.

[0014] In the above technical solution, there are two first shock absorbers. The two first shock absorbers are arranged in an inverted "V" shape, and the lower ends of the two first shock absorbers are connected to the middle of the mounting beam. The upper ends of the two first shock absorbers are inclined to be far apart from each other and are connected to the upper end of the movable frame.

[0015] The advantages of the above technical solution are: its structure is simple and it allows the two first shock absorbers to better apply vertical floating force to the mounting frame.

[0016] The shock absorption assembly described in the above technical solution further includes a second shock absorber. The second shock absorber is disposed at the lower end between the mounting frame and the movable frame in a left-right direction. One end of the second shock absorber is vertically swivelly connected to the mounting frame, and the other end of the second shock absorber is swivelly connected to the movable frame. Alternatively, one end of the second shock absorber is swivelly connected to the mounting frame, and the other end of the second shock absorber is vertically swivelly connected to the movable frame.

[0017] The beneficial effect of the above technical solution is that the second shock absorber provides shock absorption for the movement of the mounting frame in the left-right and front-back directions.

[0018] In the above technical solution, the second shock absorber is a gas spring or a shock absorber cylinder.

[0019] The advantages of the above technical solution are that it has a simple structure and good shock absorption effect.

[0020] The second objective of this invention is to provide a spray assembly with good shock absorption performance and the ability to actively adjust the tilt angle of the spray bar.

[0021] To achieve the above objectives, another technical solution of this utility model is as follows: a spray assembly, comprising two spray rods and a spray rod shock-absorbing and balancing frame as described above, wherein the two spray rods are respectively installed on both sides of the movable frame.

[0022] The advantages of the above technical solution are: its structure is simple, and the entire spray assembly has a better shock absorption effect. At the same time, the telescopic cylinder can actively drive the mounting frame to adjust the angle of the spray bar relative to the mounting frame.

[0023] The third objective of this invention is to provide a sprayer with good shock absorption performance and the ability to actively adjust the tilt angle of the spray boom.

[0024] To achieve the above objectives, another technical solution of this utility model is as follows: a sprayer, comprising the spray assembly as described above.

[0025] The advantages of the above technical solution are: its structure is simple, and it makes the spray bar have a good shock absorption effect.

[0036] 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 be more clearly described in light of 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.

[0037] Example 1

[0038] This embodiment provides a spray boom vibration damping and balancing frame, including a mounting frame 11, a movable frame 12, a telescopic cylinder 13, a linkage rod 14, and a vibration damping assembly 15. Both the mounting frame 11 and the movable frame 12 are vertically arranged in the left-right direction. The movable frame 12 is located behind the mounting frame 11 and is connected to the mounting frame 11 via the vibration damping assembly 15. The linkage rod 14 is vertically arranged above the movable frame 12 at its center, with its upper end movably connected to the upper end of the mounting frame 11 and its lower end connected to the movable frame 12. The central movable connection is provided. The telescopic cylinder 13 is arranged in the left-right direction. The telescopic cylinder 13 is movably mounted on the movable frame 12, and its telescopic end is movably connected to the linkage rod 14. The telescopic cylinder 13 extends or retracts to drive the movable frame 12 to swing relative to the mounting frame 11 to tilt or return to its original position. By mounting the movable frame on the mounting frame with a shock-absorbing component, the movable frame can float relative to the mounting frame under the action of the shock-absorbing component, which has good shock absorption performance. When it is necessary to adjust the tilt angle of the movable frame relative to the mounting frame, it is only necessary to extend or retract the telescopic cylinder.

[0039] In this embodiment, both ends of the linkage rod have universal joints, and both ends of the linkage rod are movably connected to the movable frame and the mounting frame through universal joints.

[0040] The above technical solution also includes multiple connecting rods 16. The multiple connecting rods 16 are arranged in the front-to-back direction between the mounting frame 11 and the movable frame 12. The two ends of each connecting rod 16 are movably connected to the mounting frame 11 and the movable frame 12, respectively. This makes the floating connection between the mounting frame and the movable frame more reliable. In this embodiment, four connecting rods can be provided. Both the mounting frame and the movable frame are square frames. The four connecting rods are located at the four corners between the mounting frame and the movable frame (that is, the four corners of the mounting frame and the four corners of the movable frame correspond one-to-one and are close to each other. At this time, the two ends of the connecting rods are movably connected to the corners corresponding to the mounting frame and the movable frame, respectively). Both ends of the connecting rods have universal joints, and both ends of the connecting rods are movably connected to the mounting frame and the movable frame through universal joints.

[0041] In this embodiment, the universal joints on the linkage rod and connecting rod are existing technologies, so they will not be described in detail here.

[0042] In this embodiment, the movable frame is installed in a floating manner behind the mounting frame. It can move flexibly in the vertical plane and can also be rotated to maintain a certain angle between the movable frame and the mounting frame (normally, the movable frame is parallel to the mounting frame). At the same time, the movable frame can also rotate circumferentially relative to the mounting frame (so that the four corners of the movable frame are misaligned with the four corners of the mounting frame). At this time, the movable frame can be considered to be in an inclined state relative to the mounting frame (the inclined state of the movable frame relative to the mounting frame is driven and adjusted by the telescopic cylinder. Under normal circumstances, when the telescopic cylinder is in the neutral position, the movable frame is in the reset state relative to the mounting frame, that is, the four corners of the movable frame are aligned with the four corners of the mounting frame).

[0043] In the above technical solution, both the mounting frame 11 and the movable frame 12 are hollow frames. The upper connecting frame 111 protrudes rearward from the middle of its upper end, and the lower connecting frame 121 protrudes rearward from the lower end of the middle of the rear side of the movable frame 12. The linkage rod 14 is vertically arranged behind the movable frame 12, with its upper end movably connected to the upper connecting frame 111 and its lower end movably connected to the lower connecting frame 121. A first connecting lug 141 is provided in the middle of the linkage rod 14. The movable frame 12 is also provided with a second connecting ear 122 on one side. The two ends of the telescopic cylinder 13 are respectively movably connected to the first connecting ear 141 and the second connecting ear 122 (preferably, one end of the telescopic cylinder is vertically swaying connected to the first connecting ear, while the other end of the telescopic cylinder is swaying back and forth connected to the second connecting ear. Its swaying surface can have a certain angle with the horizontal plane, and the angle is preferably acute). This makes the weight of the entire spray bar shock-absorbing balance frame lighter, thereby reducing the load on the shock-absorbing components.

[0044] The telescopic cylinder 13 mentioned in the above technical solution is a hydraulic cylinder, a telescopic pneumatic cylinder, or a telescopic electric cylinder. It has a simple structure and a large telescopic force. Preferably, the telescopic cylinder is a hydraulic cylinder, mainly because the hydraulic cylinder has a greater driving force and better stability.

[0045] The shock absorption assembly 15 described in the above technical solution includes multiple vertically arranged first shock absorbers 151. The multiple first shock absorbers 151 are all vertically arranged and spaced apart in the left and right direction. The upper end of each first shock absorber 151 is connected to the upper end of the movable frame 12, and the lower end of each first shock absorber 151 is connected to the mounting frame 11. In this way, the mounting frame can float up and down under the action of multiple first shock absorbers to perform vertical shock absorption.

[0046] In the above technical solution, a mounting beam 112 is provided in the middle of the mounting frame 11 along the left and right direction. The lower end of the first shock absorber 151 is connected to the mounting beam 112, which makes it more convenient to connect the first shock absorber to the mounting frame.

[0047] In the above technical solution, there are two first shock absorbers 151. The two first shock absorbers 151 are arranged in an inverted "V" shape, and the lower ends of the two first shock absorbers 151 are connected to the middle of the mounting beam 112. The upper ends of the two first shock absorbers 151 are inclined to be far apart from each other and are connected to the upper end of the movable frame 12. The structure is simple and allows the two first shock absorbers to better apply the vertical floating force to the mounting frame.

[0048] Specifically, in this embodiment, the first shock absorber 151 includes a vertically arranged rod 1511 and a spring 1512. The lower end of the rod is connected to the upper end of the spring. The upper end of the rod constitutes the upper end of the first shock absorber, and the lower end of the spring constitutes the lower end of the first shock absorber. In this embodiment, the rod can also be a gas spring or a shock absorber cylinder.

[0049] The shock absorption assembly 15 in the above technical solution further includes a second shock absorber 152. The second shock absorber 152 is disposed at the lower end between the mounting frame 11 and the movable frame 12 in the left-right direction. One end of the second shock absorber 152 is vertically swivelly connected to the mounting frame 11, and the other end of the second shock absorber 152 is swivelly connected to the movable frame 12. Alternatively, one end of the second shock absorber 152 is swivelly connected to the mounting frame 11, and the other end of the second shock absorber 152 is vertically swivelly connected to the movable frame 12. This allows the second shock absorber to provide shock absorption for the movement of the mounting frame in the left-right and front-back directions. Specifically, the mounting frame is provided with a third connecting ear 113, and the movable frame is provided with a fourth connecting ear 123. One end of the second shock absorber is vertically swivelly connected to the third connecting ear, and the other end of the second shock absorber is swivelly connected to the fourth connecting ear.

[0050] In the above technical solution, the second shock absorber 152 is a gas spring or a shock absorber cylinder, which has a simple structure and good shock absorption effect.

[0051] In this embodiment, the upper end of the movable frame is provided with mounting plates 124 corresponding to the connection points of each rod. Three obliquely distributed hinge positions are arranged on the mounting plates 124 along the left-right direction: a first hinge position 1241, a second hinge position 1242, and a third hinge position 1243 (the distances from the center of the movable frame to the first hinge position 1241, the second hinge position 1242, and the third hinge position 1243 decrease sequentially). Each rod's upper end is selectively connected to one hinge position, and it is preferable that the two first shock absorbers maintain a symmetrical state in the initial state. When the upper ends of both rods are connected to the first hinge position on both mounting plates, the leveling effect of the shock absorption assembly on the movable frame is the strongest (i.e., the strongest shock absorption strength). When the upper ends of both rods are connected to the second hinge position on both mounting plates, the leveling effect of the shock absorption assembly on the movable frame is moderate (i.e., the moderate shock absorption strength). When the upper ends of both rods are connected to the third hinge position on both mounting plates, the leveling effect of the shock absorption assembly on the movable frame is the weakest (i.e., the weakest shock absorption strength). That is, the three hinge positions on the mounting plate correspond to three shock absorption performance strength levels.

[0052] Example 2

[0053] This embodiment provides a spray assembly, including two spray booms 2 and a spray boom shock-absorbing and balancing frame 1 as described in Embodiment 1. The two spray booms 2 are respectively installed on both sides of the movable frame 12. Its structure is simple and provides the entire spray assembly with excellent shock absorption. Furthermore, the angle of the spray booms relative to the mounting frame can be actively adjusted by a telescopic cylinder driving the mounting frame. The installation method of the spray booms on both sides of the movable frame is prior art and will not be described in detail here.

[0054] Example 3

[0055] This embodiment provides a sprayer, including the spray assembly as described in Embodiment 2 (the sprayer includes a vehicle body, and the mounting bracket 11 is installed at the rear upper end of the vehicle body in the left-right direction. Its structure is simple and provides good shock absorption for the spray bar. At the same time, it can actively adjust the tilt angle of the spray bar relative to the ground to improve the passability of the entire sprayer. The vehicle body of the sprayer is prior art and will not be described in detail here.

[0056] The sprayer provided in this embodiment has two features. One feature is that when it operates on bumpy roads, its spray bar will not shake violently (which is reflected in the excellent shock absorption effect of its spray assembly). The other feature is that when it travels on sloping roads with uneven sides, it can actively adjust the spray bar to be in a state that is almost parallel to the road surface, thereby avoiding damage to the spray bar on one side from contact with the ground.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
