[0033] The linkage assembly 6 is arranged on the side wall of the concave frame 2. The linkage assembly 6 is transmission-connected with the clamping assembly 5. When the bearing assembly 3 moves upward, the linkage assembly 6 synchronously drives the clamping assembly 5 to clamp and fix the urea barrel.

[0034] A transverse sliding assembly 4 is also provided on the inverted concave frame 2, and the transverse sliding assembly 4 includes a rectangular guide rail 41 vertically welded on the inverted concave frame 2, and a second slide groove 42 is opened along the length direction on the two horizontal ends of the rectangular guide rail 41, and a triangular support frame 43 is also welded between the rectangular guide rail 41 and the inverted concave frame 2.

[0035] Specifically, when the urea tank recovery device is in use, the urea tank with residual residue is first fixed on the bearing assembly 3 in an inverted or horizontal position, and then the urea tank recovery device is pushed to the placement position of the urea barrel, and the urea tank recovery device and the urea barrel are relatively fixed by the clamping assembly 5 provided on the base 1, so as to realize the limited fixation of the urea tank recovery device on the one hand, and secondly, the urea tank fixed by the bearing assembly 3 and the urea barrel are relatively fixed, so as to facilitate the recovery of the residual urea in the urea tank into the urea barrel;

[0036] During the recycling process, the supporting assembly 3 is first controlled to move upward so that the supporting assembly 3 moves upward to a position opposite to the transverse sliding assembly 4, and then the urea tank on the supporting assembly 3 is controlled to slide onto the transverse sliding assembly 4 so that the urea tank is located directly above the urea barrel, and the opening on the urea tank is opened so that the remaining urea inside flows into the urea barrel for collection.

[0038] The bearing assembly 3 includes a sliding seat 31, which is slidably connected in the concave frame 2. Two parallel strip seats 32 are vertically welded on one side wall of the sliding seat 31. A first slide groove 33 is provided on the upper surface of the strip seat 32 along the length direction. A bearing platform 34 is provided on the strip seat 32. A slider 35 is welded on the lower surface of the bearing platform 34, and the slider 35 is slidably connected to the first slide groove 33.

Then, when the bearing assembly 3 is controlled to move to a position relative to the transverse sliding assembly 4, the hydraulic telescopic rod 38 is controlled to contract, and the protrusion 37 is pulled to move. The protrusion 37 drives the bearing platform 34 to move, and drives the slider 35 to slide from the first slide groove 33 to the second slide groove 42 provided on the rectangular guide rail 41, so that the urea tank fixed in the bearing platform 34 moves to the top of the urea barrel.

The top bolt of the inverted concave frame 2 is fixed with a screw motor 72 that drives the screw 71 to rotate.

[0041] Specifically, the driving mechanism 7 is used to drive the bearing assembly 3 to move up and down in the concave frame 2. When in use, the screw motor 72 is controlled to work, and the screw motor 72 drives the screw 71 to rotate. The rotation of the screw 71 drives the sliding seat 31 to move, and the sliding seat 31 drives the entire bearing assembly 3 to move.

[0042] The clamping assembly 5 includes a concave seat 51 welded on the base 1, a U-shaped clamping seat 52 is fixed on the concave seat 51, a clamping seat 53 is welded on the outer walls of the two vertical ends of the U-shaped clamping seat 52, a rotating shaft 54 ​​is rotatably connected to the clamping seat 53, the top end of the rotating shaft 54 ​​is located above the clamping seat 53 and a clamping claw 55 is fixed thereon, and the bottom end of the rotating shaft 54 ​​is located below the clamping seat 53 and a driving gear 56 is fixed thereon.

[0043] Specifically, the clamping assembly 5 works in the following manner: controlling the movement of the urea tank recovery device so that the U-shaped clamping seat 52 is sleeved on the outside of the urea barrel, and then controlling the rotation of the rotating shaft 54 ​​to drive the two clamping claws 55 to close each other, thereby clamping and fixing the urea barrel. Thus, by setting the clamping assembly 5, the urea tank recovery device and the urea barrel are relatively fixed. On the one hand, the position limit fixation of the urea tank recovery device is achieved to improve the stability of its use. Secondly, the urea tank fixed by the bearing assembly 3 is relatively fixed to the urea barrel, which is convenient for recovering the remaining urea in the urea tank into the urea barrel.

[0044] The linkage assembly 6 includes a strip-shaped drive seat 61, which is slidably connected to the side wall of the base 1, a rack 611 is welded on one side wall of the strip-shaped drive seat 61, and the rack 611 is meshed with the drive gear 56, a fixing block 63 is welded on one end of the side wall of the base 1 away from the clamping assembly 5, a spring 64 is welded between the fixing block 63 and the strip-shaped drive seat 61, a wedge-shaped groove 62 is penetrated through the upper surface of the strip-shaped drive seat 61, a wedge-shaped block 65 is inserted in the wedge-shaped groove 62, and a wedge-shaped block 65 is inserted in the wedge-shaped groove 62. A driving rod 67 is welded to the top of the block 65, an upper fixing sleeve 612 is welded to the upper part of the side wall of the inverted concave frame 2, and the upper fixing sleeve 612 is sleeved on the driving rod 67.

A positioning groove 69 used in conjunction with the linkage rod 610 is opened on the driving block 68.

[0045] Specifically, the linkage assembly 6 is used in the following manner: when the bearing assembly 3 is controlled to move upward by the driving assembly 7, the driving block 68 is synchronously driven to move upward. As the driving block 68 moves upward, it will contact the linkage rod 610 and drive the linkage rod 610 to move upward. The linkage rod 610 moves upward and drives the wedge block 65 to move upward through the driving rod 67. The wedge block 65 moves upward and pushes the bar driving seat 61 to move right. At this time, the spring 64 is in a stretched state, and the bar driving seat 61 drives the driving gear 56 to rotate through the rack 611, and the driving gear 56 drives the clamping claw 55 to close, so as to clamp and fix the urea barrel. Conversely, when the bearing assembly 3 moves downward, the linkage rod 610 moves downward, and the spring 64 rebounds. Under the elastic force of the spring 64, the bar driving seat 61 is driven to move left, and the bar driving seat 61 drives the driving gear 56 to rotate through the rack 611, and the driving gear 56 drives the clamping claw 55 to open.

[0046] There are two linkage components 6 in total, which respectively control the opening or closing of the two clamping claws 55 .

[0047] In the present embodiment, by providing a clamping component 5 and a linkage component 6, the setting of the clamping component 5 realizes the relative fixation of the urea tank recovery device and the urea barrel. On the one hand, the limited fixation of the urea tank recovery device is realized to improve the stability of its use. Secondly, the urea tank fixed by the bearing component 3 and the urea barrel are relatively fixed, which is convenient for recovering the remaining urea in the urea tank into the urea barrel. In addition, by the setting of the linkage component 6, that is, when the bearing component 3 moves up, the linkage component 6 synchronously drives the clamping component 5 to work and clamps and fixes the urea barrel. Conversely, when the bearing component 3 moves down, the linkage component 6 synchronously drives the clamping component 5 to work and releases the clamping and fixing of the urea barrel. Therefore, there is no need to set a driving mechanism for the clamping component 5, which greatly improves the convenience of its operation.
