[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a folding lifting mechanism for a boom sprayer, comprising a base plate 1, an electric telescopic rod a3 fixedly connected to the rear end surface of the base plate 1, a connecting seat 4 fixedly connected to the telescopic end of the electric telescopic rod a3, and the height of the connecting seat 4 can be adjusted by driving the electric telescopic rod a3 to adjust the spraying height according to the height of different crops and products. An electric telescopic rod b5 is hinged to the outer side wall of the connecting seat 4, and a hinge seat 6 is hinged to the telescopic end of the electric telescopic rod b5. The hinge seat 6 is hinged to the outer side wall of the electric telescopic rod b5, and the telescopic end of the electric telescopic rod b5 drives the hinge seat 6 to rotate and unfold around its rotation center point, thereby adjusting the unfolding angle of the two sets of rotating rods 8 according to the width of the crops.

[0034] Reference Figure 2 - Figure 5 The front end of the hinge seat 6 is rotatably connected to a rotating rod 8 via a limiting component 7. A clamp 9 is fixedly connected to the surface of the rotating rod 8. The clamp 9 is existing technology and can be used to position and fix the spray pipe. Thus, when the rotating rod 8 rotates and unfolds, it will also drive the clamp 9 to adjust the spray angle up and down synchronously, thereby adjusting the spray distance. Guide grooves are provided on both sides of the base plate 1. A quick-installation component 2 is detachably installed on the inner wall of the guide groove of the base plate 1. The quick-installation component 2 includes a support plate 21. The outer wall of the support plate 21 contacts the inner wall of the guide groove on both sides of the base plate 1. The contact between the two allows the support plate 21 to be adjusted on the side wall of the base plate 1. The bolt holes reserved on the vehicle are adjusted. A fixing block 22 is fixedly connected to the outer side wall of the support plate 21. The inner wall of the fixing block 22 is provided with internal threads. A threaded rod 23 is threaded through the inner wall of the fixing block 22. A contact block 24 is rotatably connected to the end of the threaded rod 23. A counterweight block 25 is in contact with the top of the outer wall of the contact block 24. By rotating the threaded rod 23, the inclined surface of the contact block 24 at its end can contact the inclined surface at the bottom of the counterweight block 25, thereby pushing the counterweight block 25 to move up and down along the slide groove of the support plate 21, thereby connecting and disconnecting the connection with the guide groove through hole of the base plate 1, so as to facilitate the movement of the support plate 21.

[0035] Reference Figure 3 and Figure 4The side wall of the support plate 21 has a sliding groove. The counterweight 25 is slidably connected to the inner wall of the sliding groove on the side wall of the support plate 21. The side wall of the support plate 21 has a sliding groove that fits the counterweight 25. The counterweight 25 is composed of a set of protrusions and a triangular block at the bottom end. The counterweight 25 itself has a certain weight. The top of the guide grooves on both sides of the base plate 1 has a through hole. The top of the outer wall of the counterweight 25 is inserted into the inner wall of the through hole. The insertion between the two can fix the support plate 21 in multiple positions that can be moved within the guide groove of the base plate 1. The inner side wall of the support plate 21 is rotatably connected to a mounting foot 26. The inner wall of the mounting foot 26 is elastically connected to a limit block 28 through a limit spring 27. One end of the limit spring 27 is fixedly connected to the outer wall of the limit block 28, and the other end of the limit spring 27 is fixedly connected to the mounting foot 26. The inner sidewall of the mounting foot 26 has a limiting spring 27 that automatically resets the position of the limiting block 28 after it is moved by the manually operated lever 29. The limiting block 28 is slidably connected to the inner wall of the mounting foot 26. The sidewall of the mounting foot 26 has a groove that fits the limiting block 28, so that the limiting block 28 can only move back and forth linearly on the inner wall of the mounting foot 26. The outer sidewall of the limiting block 28 is fixedly connected to the lever 29, which passes through and is slidably connected to the inner wall of the mounting foot 26. The inner sidewall of the support plate 21 has a limiting groove. The outer wall of the limiting block 28 is inserted into the inner wall of the limiting groove. The insertion between the two allows the mounting foot 26 to be adjusted at the angle of the mounting hole on the sidewall of the support plate 21 according to the vehicle's reserved mounting hole. The mounting foot 26 and the base plate 1 can then be fixed to the vehicle as a whole by bolts.

[0036] Reference Figure 1 and Figure 5 The limiting component 7 includes a wedge 71, which is elastically connected to the inner wall of the top of the hinge seat 6 via a return spring 72. One end of the return spring 72 is fixedly connected to the surface of the wedge 71, and the other end is fixedly connected to the inner wall of the top of the hinge seat 6. The function of the return spring 72 is to automatically reset the position of the wedge 71 after it is pulled upward. The wedge 71 is slidably connected to the inner wall of the top of the hinge seat 6. The outer wall of the rotating shaft of the rotating rod 8 is provided with a slot. The bottom end of the outer wall of the wedge 71 is inserted into the inner wall of the slot. The insertion between the two allows the rotating rod 8 to drive multiple sets of clamps 9 and the fixed spray pipes on their surface to adjust the spray angle.

[0037] Working principle: When adjusting the spray angle (up and down) of the rotating rod 8, manually pull the wedge 71 upward. The wedge 71 slides on the inner wall of the top of the hinge seat 6, stretching the return spring 72 and disengaging it from the slot of the rotating rod 8's rotating shaft, thus releasing the restriction on the rotation of the rotating rod 8. Then, rotate the rotating rod 8, which drives the clamp 9 fixed on its surface and the spray pipe to rotate together. After adjusting to the appropriate spray angle, release the wedge 71. The wedge 71 resets under the elastic restoring force of the return spring 72 and re-inserts into the slot of the rotating rod 8's rotating shaft, fixing the angle of the rotating rod 8. This achieves the up and down adjustment of the spray angle of the spray pipe, thereby adjusting the spray distance to meet the needs of different crops for spray angle and distance.

[0038] When installing the entire mechanism onto the vehicle, first adjust the position of the support plate 21 in the guide groove of the base plate 1 according to the pre-drilled bolt holes on the vehicle. Rotate the threaded rod 23. Since the threaded rod 23 and the fixed block 22 are threadedly connected, the threaded rod 23 will move along its axial direction when rotated, driving the contact block 24 at its end to move. The inclined surface of the contact block 24 contacts the inclined surface at the bottom of the counterweight 25 and generates an interaction force, pushing the counterweight 25 up and down along the slide groove of the support plate 21. When it is necessary to move the support plate 21, rotate the threaded rod 23 to move the counterweight 25 downward, disengaging it from the through hole at the top of the guide groove of the base plate 1. At this time, the support plate 21 can slide freely on the inner wall of the guide groove of the base plate 1. After adjusting to the appropriate position (corresponding to the pre-drilled bolt holes on the vehicle), rotate the threaded rod 23 in the opposite direction to move the counterweight 25 upward and reinsert it into the through hole, thus moving the support plate 21 to the correct position. The position of the support plate 21 is fixed to facilitate subsequent installation via the mounting feet 26. For adjusting the angle of the mounting feet 26 on the side wall of the support plate 21, manually move the lever 29 according to the angle requirements of the vehicle's pre-drilled mounting holes. The lever 29 causes the limiting block 28 to move linearly back and forth on the inner wall of the mounting feet 26, compressing the limiting spring 27 and disengaging the limiting block 28 from the limiting groove on the inner side wall of the support plate 21. At this point, the mounting feet 26 can rotate and adjust their angle on the side wall of the support plate 21. After adjusting to the appropriate angle, release the lever 29. The limiting block 28 resets under the elastic restoring force of the limiting spring 27 and re-inserts into the limiting groove, fixing the angle of the mounting feet 26. Then, connect the mounting feet 26 to the vehicle using bolts, thereby fixing the base plate 1 and the entire mechanism to the vehicle, completing the installation operation and ensuring the mechanism is securely installed on the vehicle for spraying operations.
