Description

Technical Field

[0001] The invention belongs to the technical field of sprayers, and in particular relates to a spray rod shock-absorbing balance frame, a spray assembly and a sprayer. Background Art

[0002] For medium and large sprayers, the overall arm span of the spray booms on both sides of the rear end is longer when unfolded, and when the road surface is uneven, the shaking of the spray boom will be doubled, so even if the vehicle body shakes slightly, the spray boom will shake greatly. Therefore, the spray boom and the vehicle body should not be rigidly installed, but a suspended shock-absorbing frame should be used for installation. At present, document No. CN200997852Y "Automatic Balancing Suspension Mechanism of Spray Boom Sprayer" discloses a balancing frame for floating spray boom installation, which can make the spray boom maintain good stability (tend to maintain a horizontal state) when the vehicle body is in a bumpy state. However, if the sprayer is on an inclined road (the two sides are not at the same height), the spray boom will remain horizontal under the action of the balancing frame and its own gravity, which can easily cause the spray boom on one side to touch the ground, which in turn affects its passability. Summary of the invention

[0005] The beneficial effect of the above technical solution is that the movable frame is installed on the mounting frame by the shock absorbing assembly, so that the movable frame can float relative to the mounting frame under the action of the shock absorbing assembly, and its shock absorbing performance is good.

According to the following description and claims, the advantages and features of the present invention will be more clearly described. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.

[0037] Example 1

[0038] The present embodiment provides a spray rod shock balancing frame, comprising a mounting frame 11, a movable frame 12, a telescopic cylinder 13, a linkage rod 14 and a shock absorbing assembly 15, wherein the mounting frame 11 and the movable frame 12 are both arranged vertically in the left-right direction, the movable frame 12 is located behind the mounting frame 11, the movable frame 12 is connected to the mounting frame 11 through the shock absorbing assembly 15, the linkage rod 14 is vertically arranged in the middle above the movable frame 12, and the upper end of the linkage rod 14 is movably connected to the upper end of the mounting frame 11, and the lower end of the linkage rod 14 is movably connected to the movable frame 12. The middle part is movably connected, the telescopic cylinder 13 is arranged in the left and right direction, the telescopic cylinder 13 is movably installed on the movable frame 12, and its telescopic end is movably connected with the linkage rod 14, the telescopic cylinder 13 extends or contracts to drive the movable frame 12 to swing relative to the mounting frame 11 to tilt or reset, and the movable frame is installed on the mounting frame by the shock absorbing assembly. In this way, the movable frame can float relative to the mounting frame under the action of the shock absorbing assembly, and its shock absorbing performance is good. When it is necessary to adjust the inclination angle of the movable frame relative to the mounting frame, it only needs to be extended or contracted by the telescopic cylinder.

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

[0040] The above technical solution also includes a plurality of connecting rods 16, and the plurality of connecting rods 16 are arranged between the mounting frame 11 and the movable frame 12 along the front-to-back direction, and the two ends of each of the connecting rods 16 are movably connected to the mounting frame 11 and the movable frame 12 respectively, so that the reliability of the floating connection between the mounting frame and the movable frame is better. In this embodiment, four connecting rods can be provided, and the mounting frame and the movable frame are both square frames, and the four connecting rods are respectively 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 to each other one by one and are close to each other, and at this time, the two ends of the connecting rod are respectively movably connected to the corners corresponding to the mounting frame and the movable frame), and both ends of the connecting rod have universal ball joints, and both ends of the connecting rod are movably connected to the mounting frame and the movable frame through universal ball joints.

[0041] Among them, the universal ball joints on the linkage rod and the connecting rod described in this embodiment are all existing technologies, so they are not described here in detail.

[0042] The movable frame in the present embodiment is installed in a floating manner behind the mounting frame, and can move flexibly in the vertical plane, and can also be flipped to maintain a certain angle between the movable frame and the mounting frame (under normal circumstances, the movable frame is maintained in a state of being parallel to the mounting frame). At the same time, the movable frame can also perform a certain circumferential rotation relative to the mounting frame (that is, 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 maintains a neutral state, the movable frame is in a 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, the mounting frame 11 and the movable frame 12 are both hollow frames, and an upper connecting frame 111 is protruded backwards from the middle of the upper end of the mounting frame 11, and a lower connecting frame 121 is protruded backwards from the lower end of the middle of the rear side of the movable frame 12, and the linkage rod 14 is vertically arranged behind the movable frame 12, and the upper end of the linkage rod 14 is movably connected to the upper connecting frame 111, and the lower end of the linkage rod 14 is movably connected to the lower connecting frame 121, and the middle part of the linkage rod 14 is provided with a first connecting ear 141 A second connecting ear 122 is also provided on one side of the movable frame 12, and the two ends of the telescopic cylinder 13 are movably connected to the first connecting ear 141 and the second connecting ear 122 respectively (preferably, one end of the telescopic cylinder is vertically swingably connected to the first connecting ear, and the other end of the telescopic cylinder is forward and backward swingably connected to the second connecting ear, and the forward and backward swinging surface and the horizontal plane can have a certain angle, and the angle is preferably an acute angle), so that the weight of the entire spray boom shock-absorbing balance frame is lighter, thereby reducing the load of the shock-absorbing component.

[0044] The telescopic cylinder 13 in the above technical solution is a hydraulic cylinder, a telescopic air cylinder or a telescopic electric cylinder, which has a simple structure and a large telescopic force. Preferably, it is better to use a hydraulic cylinder as the main reason is that the driving force of the hydraulic cylinder is larger and the stability is better.

[0045] The shock absorbing assembly 15 in the above technical solution includes a plurality of vertically arranged first shock absorbers 151, and the plurality of first shock absorbers 151 are vertically arranged and spaced apart in the left-right direction, and the upper end of each of the first shock absorbers 151 is connected to the upper end of the movable frame 12, and the lower end of each of the first shock absorbers 151 is connected to the mounting frame 11, so that the mounting frame can float up and down under the action of the plurality of 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-right direction, and the lower ends of the first shock absorbers 151 are connected to the mounting beam 112, so that the first shock absorbers are more conveniently connected to the mounting frame.

[0047] In the above technical solution, two first shock absorbers 151 are provided, and the two first shock absorbers 151 are distributed in an inverted "eight" shape, and the lower ends of the two first shock absorbers 151 are connected to the middle part of the mounting beam 112, and the upper ends of the two first shock absorbers 151 are inclined to move away from each other and are connected to the upper end of the movable frame 12. The structure is simple, and the two first shock absorbers can better exert an up and down floating force on the mounting frame.

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

[0049] The shock absorbing assembly 15 in the above technical solution also includes a second shock absorber 152, which is arranged 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 swingably connected to the mounting frame 11, and the other end of the second shock absorber 152 is connected to the movable frame 12 for front-back swinging, or one end of the second shock absorber 152 is connected to the mounting frame 11 for front-back swinging, and the other end of the second shock absorber 152 is vertically swingably connected to the movable frame 12, so that the second shock absorber provides shock absorbing effect for the movement of the mounting frame in the left-right direction and the front-back direction. Specifically, a third connecting ear 113 is provided on the mounting frame, and a fourth connecting ear 123 is provided on the movable frame, one end of the second shock absorber is vertically swingably connected to the third connecting ear, and the other end of the second shock absorber is connected to the fourth connecting ear for front-back swinging.

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

[0051] In this embodiment, the upper end of the movable frame corresponds to the connection of each rod body and is respectively provided with a mounting plate 124. The mounting plate 124 is provided with three obliquely distributed hinge positions along the left and right directions, namely a first hinge position 1241, a second hinge position 1242 and a third hinge position 1243 (the distances between the first hinge position 1241, the second hinge position 1242 and the third hinge position 1243 and the middle part of the movable frame decrease successively, and the upper end of each rod body is selectively connected to a hinge position for swinging, and the two first shock absorbers are preferably kept in a symmetrical state in the initial state. When When the upper ends of the two rod bodies are connected to the first hinge positions on the two mounting plates, the leveling effect of the shock absorbing assembly on the movable frame is the strongest (i.e., the shock absorbing strength is the strongest); when the upper ends of the two rod bodies are connected to the second hinge positions on the two mounting plates, the leveling effect of the shock absorbing assembly on the movable frame is medium (i.e., the shock absorbing strength is medium); when the upper ends of the two rod bodies are connected to the third hinge positions on the two mounting plates, the leveling effect of the shock absorbing assembly on the movable frame is the weakest (i.e., the shock absorbing strength is the weakest), i.e., the three hinge positions on the mounting plates correspond to three shock absorbing performance strength gears).

The two spray rods 2 are respectively installed on both sides of the movable frame 12. The structure is simple, and the entire spray assembly has a better shock-absorbing effect. At the same time, the mounting frame can be actively driven by the telescopic cylinder to drive the spray rod to adjust the angle relative to the mounting frame. Among them, the installation method of the spray rod on both sides of the movable frame belongs to the prior art and will not be described in detail here.

[0054] Example 3

At the same time, the inclination angle of the spray rod relative to the ground can be actively adjusted to improve the passability of the entire sprayer. The body of the sprayer belongs to the prior art and will not be described in detail here.

[0056] The sprayer provided in this embodiment has two characteristics. One characteristic is that when it is operating on a bumpy road, its spray rod will not shake violently (which is reflected in the good shock absorption effect of its spray assembly). The second characteristic is that when it is driving on an inclined road with unequal heights on both sides, it can actively adjust the spray rod to be nearly parallel to the road surface for driving, thereby avoiding the spray rod on one side from touching the ground and being damaged.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
