[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an agricultural sprayer cross-type spraying rod, including a crossbeam 1, the crossbeam 1 is used to connect with the spraying vehicle, the right end of the crossbeam 1 is fixedly connected to a connecting block 2, and a storage mechanism is provided on the upper surface of the crossbeam 1. The storage mechanism can store the expansion arm 4, reducing space occupancy and facilitating the transportation and travel of the spraying vehicle. The storage mechanism includes a folding component and a buffer component. The folding component includes a mounting seat 34, the mounting seat 34 is fixedly connected to the upper surface of the connecting block 2, and the upper surface of the mounting seat 34 is hinged with an expansion arm 4, which can be unfolded. The expansion arm 4 is a conventional The technology is prior art, and can be realized by technicians in this field. Since it is prior art, it will not be described in detail in this case. The expansion arm 4 rotates with the mounting seat 34 as the axis. The upper surface of the beam 1 is fixedly connected with an articulated seat 31, and the top of the articulated seat 31 is hinged with one end of a hydraulic cylinder 32. The hydraulic cylinder 32 is prior art, and can be realized by technicians in this field. Since it is prior art, it will not be described in detail in this case. The bottom end of the left surface of the expansion arm 4 is fixedly connected with an articulated seat 2 33, and the other end of the hydraulic cylinder 32 is hinged to the left end of the articulated seat 2 33.

[0031] Reference Figure 1 、 Figure 2 、 Figure 4 The buffer assembly includes a support rod 51, which is set to be U-shaped. The support rod 51 is fixedly connected to the front surface of the beam 1. The support rod 51 is elastically connected to the slide rod 53 through a compression spring 54. The upper surface of the slide rod 53 is fixedly connected to a baffle 52. The baffle 52 is set to be arc-shaped and is inclined. When the expansion arm 4 falls, it can contact the baffle 52.

[0032] Reference Figure 1 - Figure 3The mounting seat 34 is set to be inclined, the hinged seat 31 is set to be inclined, the hinged seat 31 and the mounting seat 34 are aligned, and the inclination angles of the two are the same. After the hydraulic cylinder 32 is started, the output shaft will be extended and retracted, which can drive the expansion arm 4 to swing and can be cross-stored.

[0033] Reference Figure 1 、 Figure 2 、 Figure 4 One end of the compression spring 54 is fixedly connected to the upper surface of the slide rod 53, and the other end of the compression spring 54 is fixedly connected to the lower surface of the support rod 51. The slide rod 53 passes through and is slidably connected to the upper surface of the support rod 51. When the baffle 52 is squeezed, it will drive the slide rod 53 to move downward. The downward moving slide rod 53 will stretch the compression spring 54 to generate a reaction force. The folding assembly, buffer assembly, connecting block 2, and expansion arm 4 are provided in two groups. The two groups of folding assemblies, buffer assemblies, connecting block 2, and expansion arm 4 are arranged in a circular array with the center point of the beam 1.

[0034] Example 2:

[0035] Reference Figure 1 、 Figure 5 The difference between the second embodiment and the first embodiment is that the crossbeam 1 in the second embodiment adopts a thickened design, and the two sets of connecting blocks 2 are respectively located at the rear end of the right surface of the crossbeam 1 and the front end of the left surface of the crossbeam 1, and the two sets of expansion arms 4, the first articulated seat 31, the mounting seat 34, the hydraulic cylinder 32 and the second articulated seat 33 are also distributed in a front-to-back staggered manner, so that the two sets of expansion arms 4 will appear in a cross shape when stored.

[0036] Working principle: When this device is used, starting the hydraulic cylinder 32 to extend and retract can pull the articulated seat 2 33, and then can drive the expansion arm 4 to rotate with the mounting seat 34 as the axis. The hydraulic cylinder 32 will also rotate with the articulated seat 1 31 as the axis when extending and retracting. And because the articulated seat 1 31 and the mounting seat 34 are arranged in an inclined shape, the two sets of expansion arms 4 will be in a crossed state after the storage is completed, and will not cause collision or obstruction.

[0037] When the expansion arm 4 is rotated and stored, it will contact the baffle 52. When contacting the baffle 52, it will squeeze the baffle 52 and then drive the slide bar 53 to move downward. The downward moving slide bar 53 will stretch the compression spring 54 to generate a reaction force. The baffle 52 will produce a certain displacement and provide support for the expansion arm 4 in real time, which can achieve a buffering effect. After the two groups of expansion arms 4 are cross-stored, the hydraulic cylinder 32 can be closed to complete the folding and storage of the expansion arm 4. After the storage is completed, the baffle 52 and the support rod 51 can provide stable support for the expansion arm 4.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
