The setting of the knocking hammer has the effect of knocking the outer wall of the feed hopper.

[0006] Preferably, a support plate is fixedly mounted on the side of the test box, a motor is fixedly mounted on the surface of the support plate, and a special-shaped gear is fixedly mounted on the output end of the motor.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting a clamping device, when it is necessary to prevent soil from adhering to the inside of the lower hopper, the motor is started first, and the motor starts to drive the special-shaped gear to rotate. When the special-shaped gear rotates and meshes with the tooth-like structure on the left inner wall of the strip frame, the strip frame moves forward, and the strip frame moves forward to drive the slide plate to move on the surface of the slide rod. At the same time, the strip frame moves forward to drive the support rod to move forward, and the support rod moves forward to drive the hammer to move forward. The hammer moves forward to knock on the outer wall of the lower hopper, thereby shaking off the soil adhering to the inner wall of the lower hopper. When the special-shaped gear rotates and engages with the tooth-like structure on the left inner wall of the strip frame, the strip frame moves forward to drive the slide plate to move on the surface of the slide rod. At the same time, the strip frame moves forward to drive the support rod to move forward, and the support rod moves forward to drive the hammer to move forward. The hammer moves forward to knock on the outer wall of the lower hopper, thereby shaking off the soil adhering to the inner wall of the lower hopper. When the gear and the tooth-like structure on the right inner wall of the bar frame are meshed, the bar frame will move backwards, and the movement of the bar frame backwards drives the support rod and the knocking hammer to move backwards. The knocking hammer moves backwards to separate itself from the lower hopper. As the motor drives the special-shaped gear to rotate continuously, the knocking hammer continuously knocks on the feed hopper repeatedly, and the soil adhered to the inside of the hopper is shaken off into the inside of the test box. Through the cooperation of the above structure, the effect of shaking off the soil adhered to the inner wall of the feed hopper is achieved, thereby avoiding the deviation in the ratio between the soil and the repair liquid, which leads to inaccurate experimental results.

[0013] 2. In the utility model, a stirring and cutting device is provided. When the device needs to be used, soil and repair liquid are first put into the interior of the test box with the help of a feed hopper, and then the operating rod is pushed. The movement of the operating rod drives the L-shaped plate to move inside the long groove. The movement of the L-shaped plate inside the long groove drives the sliding plate to move inside the sliding groove. The movement of the sliding plate inside the sliding groove drives the rack to move. The rack moves and engages with the first gear, thereby causing the first gear to rotate. The rotation of the first gear drives the rotating rod to rotate. The rotation of the rotating rod drives the cutting blade to rotate. The cutting blade rotates to cut the soil. At the same time, the mixing effect of the repair liquid and the soil can be accelerated. Through the cooperation of the above-mentioned structure, the soil repair efficiency can be improved, thereby improving the practicality of the device when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Working principle: By setting the knocking device 4, when it is necessary to prevent soil from adhering to the inside of the lower hopper, the motor 47 is started first, and the motor 47 starts to drive the special-shaped gear 48 to rotate. When the special-shaped gear 48 rotates and meshes with the tooth-like structure on the left inner wall of the bar frame 43, the bar frame 43 moves forward, and the bar frame 43 moves forward to drive the slide plate 42 to move on the surface of the slide rod 41.

When the tooth-like structure of the special-shaped gear 48 and the right inner wall of the bar frame 43 are meshed, the bar frame 43 will move backward, and the backward movement of the bar frame 43 drives the support rod 44 and the knocking hammer 45 to move backward. The knocking hammer 45 moves backward to separate itself from the lower hopper, and as the motor 47 drives the special-shaped gear 48 to rotate continuously, the knocking hammer 45 continuously knocks the feed hopper 3 repeatedly, and the soil adhered to the inside thereof is shaken off into the inside of the test box 1. Through the cooperation of the above-mentioned structure, the effect of shaking off the soil adhered to the inner wall of the feed hopper 3 is achieved, thereby avoiding the deviation in the ratio between the soil and the repair liquid, which leads to inaccurate experimental results. When the device is needed, first, the soil and the repair liquid are put into the interior of the test box 1 with the help of the feed hopper 3, and then the operating rod 59 is pushed. The operating rod 59 moves to drive the L-shaped plate 58 to move inside the long groove 57.

The rack 55 moves and engages with the first gear 56, thereby causing the first gear 56 to rotate. The rotation of the first gear 56 drives the rotating rod 51 to rotate. The rotation of the rotating rod 51 drives the cutting blade 52 to rotate. The cutting blade 52 rotates to cut the soil, and at the same time, it can also accelerate the mixing effect of the repair liquid and the soil. Through the cooperation of the above-mentioned structure, the soil repair efficiency can be improved, thereby improving the practicality of the device when used.
