[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] Example 1

[0024] like Figure 1 , 2 3, the sprayer connecting frame assembly of this embodiment is used to connect the intermediate frame 4, including a connecting frame 1, a boom 2 and two connecting rods 3, the connecting frame 1 is vertically arranged along the left-right direction, the intermediate frame 4 is vertically arranged along the left-right direction at the rear side of the connecting frame 1, the boom 2 is hinged to the upper front side of the connecting frame 1, the boom 2 is symmetrically provided with boom beams 21 extending forward thereof on the left and right sides, the two connecting rods 3 are symmetrically arranged at the lower ends of the two boom beams 21, and one end of the connecting rod 3 is connected to the connecting frame 1. The lower front part of the connecting rod 3 is hinged, and the other ends of the connecting rod 3 extend toward the front of the connecting frame 1 and are parallel to the boom beam 21. The left and right ends of the upper rear part of the connecting frame 1 are respectively movably connected with the intermediate frame body 4 through the pull plate assembly 5. The lower rear end of the connecting frame 1 is provided with a limiting rod 6 extending along the left and right directions, and the middle part of the lower end of the front side of the intermediate frame body 4 is provided with a protrusion 41, and the limiting rod 6 passes through the protrusion 41. The two ends of the limiting rod 6 are respectively provided with elastic telescopic parts 61 connected with the two ends of the protrusion 41.

[0025] During use, spray rods are installed on the left and right ends of the middle frame 4, the front end of the boom beam 21 and the front end of the connecting rod 3 (that is, the other end of the connecting rod 3) are connected to the frame of the sprayer, and a parallelogram structure is formed between the boom beam 21 and the connecting rod 3 below. Since the connecting frame 1 and the middle frame 4 are movably connected through the pull plate assembly 5, and the protrusion 41 and the limit rod 6 are through-fitted, there is a certain amount of activity between the middle frame 4 and the connecting frame 1. When the sprayer vibrates when passing through a bumpy road, the connection structure of the pull plate assembly 5 and the middle frame 4 and the design of the elastic telescopic part 61 enable the middle frame 4 to obtain a certain degree of force balance and buffering during the vibration process, thereby reducing the amplitude of its vibration. The overall structural design is simple and reasonable, and can effectively reduce the shaking caused by the spray rod when the vehicle shakes.

[0026] It should be noted that during the vibration of the intermediate frame 4, it will move left and right relative to the limit rod 6, and the elastic telescopic parts 61 at its left and right ends will be compressed during the movement. At the same time, the pull plate assembly 5 and the intermediate frame 4 are movably connected, which can also balance a certain vibration force.

[0027] As a preferred embodiment, Figure 3 and4 As shown, ball joint supports 11 are respectively installed at the left, right, upper and lower positions on the front side of the connecting frame 1, and ear seats 7 corresponding to the ball joint supports 11 are respectively provided on the left and right sides of the rear end of the boom 2 and one end of the connecting rod 3. Connecting shafts (denoted by b in the figure) are provided in the ear seats 7, and the connecting shafts respectively pass through the corresponding spheres (denoted by c in the figure) in the ball joint supports 11.

[0028] In the above embodiment, since the rear end of the boom 2 and one end of the connecting rod 3 pass through the corresponding sphere in the spherical joint support 11 through the connecting shaft respectively, the sphere can rotate freely, and the structure is easy to install.

[0029] It should be particularly emphasized that the ball joint support 11 is a product of the prior art, and its specific structure will not be described in detail here.

[0030] In this embodiment, the boom 2 and the boom beam 21 are integrally welded to form a C-shaped or gate-shaped component.

[0031] As a preferred embodiment, the front end of the boom beam 21 and the other end of the connecting rod 3 are respectively hinged to the frame, and telescopic cylinders are respectively installed between the left and right ends of the rear end of the boom beam 21 and the upper parts of the other ends of the two connecting rods 3.

[0032] In the above implementation scheme, the design changes the traditional installation of the telescopic cylinder on the frame to an installation between the boom beam 21 and the connecting rod 3, and the telescopic cylinder is installed on the diagonal of the parallelogram formed between the boom beam 21 and the connecting rod 3. The overall lifting of the connecting frame 1 and the intermediate frame 4 is more flexible and convenient, and the installation structure is more compact.

[0033] As a preferred embodiment, the elastic telescopic member 61 is a spring, and the limiting rod 6 is provided with limiting rings at the positions corresponding to the two ends of the elastic telescopic member 61, and the elastic telescopic member 61 is sleeved on the limiting rod 6, and its two ends are respectively connected with the corresponding limiting rings.

[0034] In the above-mentioned implementation scheme, a limiting ring is fixedly installed at the position of the limiting rod 6 near its two ends, and a limiting ring is movably sleeved on the position of the limiting rod 6 close to the left and right ends of the protrusion 41, and an elastic telescopic member 61 is sandwiched between the two limiting rings. The elastic telescopic member 61 itself is in a compressed state. When the sprayer vibrates, the intermediate frame 4 may shake left and right relative to the limiting rod 6. After this phenomenon occurs, the elastic telescopic members 61 at both ends are compressed or released to different degrees, thereby reducing the vibration of the intermediate frame 4 and the spray rod.

[0035] As a preferred embodiment, the pull plate assembly 5 includes two strip-shaped pull plates 51 arranged in parallel front and back, and the left and right ends of the upper rear side of the connecting frame 1 are respectively provided with connecting parts, and the connecting parts extend into the intermediate frame 4. One ends of the two pull plates 51 are respectively connected to the lower ends of the connecting parts, and the other ends of the two pull plates 51 extend obliquely downward to the front and rear sides of the intermediate frame 4, and the other ends of the two pull plates 51 are connected to the intermediate frame 4 by bolts passing through the two.

[0036] In the above embodiment, the pull plate assembly 5 has a reasonable structural design and a compact connection structure with the intermediate frame 4. The intermediate frame 4 includes a plurality of beams connected in a crisscross pattern. The other ends of the pull plate 51 are respectively located at the front and rear sides of one of the beams and are connected by bolts passing through the beam. The bolts only pass through the intermediate frame 4 and are not threadedly connected to each other. Nuts are respectively arranged at both ends of the bolts.

[0037] In this embodiment, the two groups of the pull plate assemblies 5 are distributed in an "eight" shape.

[0038] As a preferred embodiment, the rear side of the connecting frame 1 is provided with four "door" type limit slots 12, two of which are distributed on the upper left and right sides of the rear side of the connecting frame 1, and the other two are distributed on the lower left and right sides of the rear side of the connecting frame 1. The upper and lower parts of the intermediate frame 4 are respectively provided with limit beams 42 extending left and right, and the two limit beams 42 extend into the upper or lower limit slots 12 respectively.

[0039] In the above implementation scheme, the limiting beam 42 is always embedded in the limiting slot 12 in a "half-wrapped" state, which limits the limiting beam 42 (that is, the middle frame 4) in the five directions of front, rear, left, right and top, thereby preventing the middle frame 4 from having a large displacement margin relative to the connecting frame 1.
