DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 A trough structure of a concrete mixer truck in this embodiment includes a trough frame 1, a trough plate 2 is attached to the upper surface of the trough frame 1, and a fixing component 3 is provided in the trough frame 1 and penetrates to the outside thereof.

[0024] It should be noted that the fixing assembly 3 makes it easier for the operator to install or disassemble the trough plate 2, which is convenient for subsequent maintenance or processing, saves time and energy, and further improves work efficiency.

[0025] See also Figure 1-3The worm 301 is fixed with a handle 302 on one side of the worm 301 and a worm gear 303 is engaged with the worm gear 303 on the other side of the worm 301. The worm 301 is fixed with a handle 302 on the other side of the worm 301 and a worm gear 303 is engaged with the worm gear 303 on the other side of the worm 301. The worm gear 303 is engaged with the worm gear 303 on the other side of the worm 301 and a threaded rod 304 is fixed on the inner wall of the axis of the worm gear 303 and is rotatably connected with the upper and lower sides of the inner cavity of the adjusting groove 313 through bearings. The worm 301 is driven to rotate by rotating the handle 302, thereby driving the threaded rod 304 to rotate, thereby providing a power source for the operation of the adjusting assembly.

[0026] Among them, the cross-section of the adjustment groove 313 is convex, and a sealing ring is fixed on the inner wall of the adjustment groove 313. The inner wall of the sealing ring fits with the worm 301, so that when working, concrete debris will not enter the interior through the adjustment groove 313 and affect the subsequent fixation or disassembly. Pull handles are fixed on both sides of the trough plate 2, so that the user can move the trough plate 2 out or into the guide hole 312 more conveniently, further reducing the burden on the user.

[0027] At the same time, the adjustment component includes an adjustment block 305 threadedly connected to the outer surface of the threaded rod 304, a connecting rod 306 is fixed between the opposite sides of the two adjustment blocks 305, and two limit rods 307 are fixed on the lower surface of the connecting rod 306. T-shaped sliders 308 are fixed on the opposite sides of the two adjustment blocks 305. Guide holes 312 are provided on the left and right sides of the trough frame 1. The inner wall of the guide hole 312 is slidably connected to the trough plate 2. The lower surface of the adjustment groove 313 is connected to two adjustment holes 310 provided on the trough frame 1. The bottom of the adjustment hole 310 is connected to the guide hole 312. The fixing component 3 also includes guide rails 309 fixed to the left and right sides of the inner wall of the adjustment groove 313. The guide rails 309 are fixed to the left and right sides of the inner wall of the adjustment groove 313. 9 is provided with a T-slot adapted to the T-slider 308, so that the T-slider 308 is always located on the inner wall of the guide rail 309 when following the adjustment block 305 to move, and will not slide out, thereby providing support for the stable movement of the connecting rod 306. The fixing component 3 also includes two sets of limit grooves 311 provided on the upper surface of the trough plate 2. The limit grooves 311 and the adjustment holes 310 are both slidably connected to the limit rod 307, so that the limit rod 307 can be better moved into or out of the limit groove 311. The connecting rod 306 and the limit rod 307 are driven to move by the adjustment block 305, and the positional relationship between the limit rod 307 and the limit groove 311 is adjusted, thereby achieving the fixation of the trough plate 2.

[0028] It should be noted that the driving component provides a power source for the adjusting component, and then through the movement and adjustment of the adjusting component, the trough plate 2 can be conveniently disassembled and assembled, further facilitating the operator to replace or maintain the trough plate 2.

[0029] The working principle of the above embodiment is:

[0030] When the trough plate 2 needs to be replaced and repaired, the handle 302 is turned to drive the worm 301 to rotate, thereby driving the two worm wheels 303, and the two threaded rods 304 are caused to rotate through the meshing force, so that the two adjustment blocks 305 can move in the same direction. At this time, the T-shaped slider 308 will move along the guide rail 309 with the movement of the adjustment block 305, and the connecting rod 306 will also move with the two adjustment blocks 305, so that the movement of the two adjustment blocks 305 can be more stable, so the connecting rod 306 and the limit rod 307 can be driven to move more stably. When the limit rod 307 moves along the adjustment hole After 310 moves completely out to the inside of the limit slot 311 on the trough plate 2, the position of the trough plate 2 is no longer fixed, so the positions of the trough frame 1 and the trough plate 2 will not be fixed either, and then the trough plate 2 can be slid along the guide hole 312 through the handles on the left and right sides of the trough plate 2 until the trough plate 2 is completely slid out of the guide hole 312, so that the trough plate 2 can be quickly installed or disassembled, which is convenient for later maintenance or processing, and can also avoid the loss of parts during the disassembly and assembly of the trough plate 2 by bolts, further improving work efficiency and saving user energy.
