[0001] The utility model relates to the technical field of engineering machinery, in particular to a bulldozer with a hopper separation function. Background Art

[0002] A bulldozer is an earth-moving machinery that can dig, transport and dump rock and soil. It is widely used in open-pit mines, for example, to build dumping sites, level automobile dumping sites, pile up scattered ore and rock, level work platforms and construction sites, etc. It is not only used for auxiliary work, but also for major mining work, such as: stripping and mining of sand ore deposits, traction and boosting of scrapers and plows, and cooperating with other earth-moving machinery to reduce the height of the stripping steps in the case of non-transportation mining method.

[0003] A Chinese patent discloses a bulldozer (authorization announcement number CN207121946U), which shields the side of the bucket by a baffle and prevents soil from falling out of the side of the bucket.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: although existing bulldozers have some separation or classification functions during the bulldozing process, the screen plates are mostly fixedly installed, which makes it impossible to quickly replace the screen plates, making it inconvenient to separate materials of different sizes, weights or properties, thereby reducing the practicability of the equipment and affecting its work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the prior art has the disadvantage that the screen plate in the bulldozer with the hopper separation function cannot be quickly replaced. For this reason, we propose a bulldozer with the hopper separation function.

[0007] Preferably, first springs are fixed on both sides of the interior of the shell, and the other end of the first spring is fixed to the moving plate.

[0008] Preferably, the difference between the maximum diameter and the minimum diameter of the limiting plate is greater than the distance that the limiting rod is inserted into the limiting groove.

[0009] Preferably, a square rod is slidably connected inside the rotating shaft, a knob is fixed to one end of the square rod, an insertion rod is fixed to one side of the knob, a slot is opened on the top of the shell, and the inside of the slot is plugged with the insertion rod.

[0010] Preferably, both sides of the rotating shaft are provided with sliding grooves, the interior of the sliding groove is slidably connected with a slider, and the other end of the slider is fixed to the square rod.

[0011] Preferably, a second spring is fixed inside the rotating shaft, and the other end of the second spring is fixed to one end of the square rod.

[0012] Preferably, mounting grooves for use with the screen plate are provided at both upper and lower ends of the interior of the hopper body.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, the insertion rod is driven to disengage from the inside of the slot by pulling the knob, and then the knob can be turned, and the square slot opened inside the rotating shaft is used in conjunction with the square rod, so that the rotating shaft drives the limit plate to rotate, and the limit on the movable plate is released. The rebound force of the first spring pushes the movable plate to drive the limit rod to disengage from the inside of the limit slot. At this time, the fixation of the connecting block can be released, and then the screen plate can be quickly disassembled and replaced, so that screen plates with different apertures can be installed, so as to separate materials of different sizes, weights or properties, and to achieve preliminary separation of materials while bulldozing, thereby reducing the time and cost of subsequent processing, thereby improving overall work efficiency.

At this time, the knob 13 can be turned to use the square slot provided inside the rotating shaft 6 in conjunction with the square rod 12 to make the rotating shaft 6 drive the limiting plate 7 to rotate, thereby releasing the limit on the movable plate 8. The rebound force of the first spring 11 pushes the movable plate 8 to drive the limiting rod 9 out of the limiting slot 10. At this time, the fixation of the connecting block 4 can be released, and the screen plate 3 can be quickly disassembled and replaced, so as to install the screen plates 3 with different apertures, so as to separate materials of different sizes, weights or properties, and to achieve preliminary separation of materials while bulldozing, thereby reducing the time and cost of subsequent processing, thereby improving the overall The working efficiency of the body is improved. By designing the difference between the maximum diameter and the minimum diameter of the limit plate 7 to be larger than the distance that the limit rod 9 is inserted into the limit groove 10, it can be ensured that the moving distance of the movable plate 8 can make the limit rod 9 disengage from the inside of the limit groove 10. By setting the structure of the slide groove 16 and the slider 17, it can be prevented that the user uses too much force when pulling the knob 13, causing the square rod 12 to disengage from the inside of the rotating shaft 6 and affecting the fixing effect of the knob 13. By setting the second spring 18, it can constrain the position of the insertion rod 14 and save manpower when fixing the knob 13.
