[0015] 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.

[0016] Example Please see Figure 1-5 This embodiment provides the following technical solution: a loader loading pool screening device, including a screen frame 10, with a plurality of spaced anti-collision plates 20 arranged on the inclined surface of the screen frame 10. The two adjacent anti-collision plates 20 cooperate to form a sand and gravel screening area. A screening frame 30 is detachably connected to the screening area. A plurality of spaced screen rods 40 are detachably connected to the screening frame 30. The plurality of screen rods 40 cooperate to form a sand and gravel screening structure. By setting the anti-collision plates 20, the screen rods 40 are protected, avoiding the problem that the bucket will collide with the screen rods 40 during the unloading process, causing the screen rods 40 to deform due to external force. This reduces the maintenance cost of the device and improves the screening effect and efficiency of sand and gravel.

[0017] Both sides of the screen frame 10 are fixedly connected with baffles 50. The baffles 50 can block the qualified sand and gravel after screening, which is conducive to the temporary storage of sand and gravel on the back side of the screening frame 30, and facilitates the subsequent transfer of qualified sand and gravel by a loader.

[0018] The screen frame 10 includes a main board 11. Multiple lower plates 12 are fixedly connected to the rear side of the main board 11. The lower plates 12 are on the same horizontal plane as the main board 11 and are perpendicular to the main board 11. A vertical plate 13 is fixedly connected to the rear end of each lower plate 12, and the vertical plate 13 is perpendicular to the lower plate 12. The multiple vertical plates 13 are fixedly connected to each other by multiple reinforcing plates 16. The upper end of each vertical plate 13 is fixedly connected to the front end of each lower plate 12 by inclined plates 14. The multiple inclined plates 14 are fixedly connected to each other by multiple support plates 15. Each support plate 15 is connected to each inclined plate... All 14 are vertically arranged, and multiple support plates 15 are distributed at intervals along the length of the inclined plate 14. In some embodiments, the lower plate 12, the vertical plate 13 and the inclined plate 14 work together to form a right-angled triangle structure, so that the screening frame 30 is tilted at a certain angle. When the bucket pours sand and gravel onto the upper part of the screening frame 30, the sand and gravel will slide down the screening frame 30. Smaller particles will pass through the screening frame 30 and fall to the rear side of the screening frame 30, while larger particles will fall to the front side of the screening frame 30, thus completing the screening operation of the sand and gravel.

[0019] The screening frame 30 includes two parallel side plates 31. The bottom ends of the two side plates 31 are fixedly connected to each other by a bottom plate 32, and the top ends of the two side plates 31 are detachably connected to each other by a top plate 33. A limiting sleeve 34 corresponding to the screen rod 40 is fixedly connected to the opposite side of the top plate 33 and the bottom plate 32. The limiting sleeve 34 is provided with an insertion cavity for the screen rod 40 to be inserted. In some embodiments, the bottom plate 32, the top plate 33 and the two side plates 31 work together to form a rectangular structure. The detachably connected top plate 33 facilitates the disassembly and assembly of each screen rod 40, so that the screen rod 40 can be repaired or replaced.

[0020] In some embodiments, the anti-collision plate 20 and the support plate 15 are arranged perpendicular to each other, and the anti-collision plate 20 is arranged along the length direction of the inclined plate 14. The distance between the screening frame 30 and the support plate 15 is smaller than the distance between the anti-collision plate 20 and the support plate 15. During the process of the loader driving the bucket to move towards the screen frame 10, the bucket will contact the anti-collision plate 20, and there will be no problem of the bucket contacting the screen rod 40.

[0021] The top plate 33 is detachably connected to the side plates 31 on the left and right sides by first bolts 35. One end of the first bolt 35 passes through the bolt groove above the top plate 33 and is threadedly connected to the threaded hole on the side plate 31, which facilitates the disassembly and assembly of the top plate 33.

[0022] A locking mechanism 70 is provided above the top plate 33 for locking and fixing the screening frame 30. The locking mechanism 70 includes a locking plate 71 and a pressing plate 72. The locking plate 71 is detachably connected to the uppermost support plate 15. The other end of the locking plate 71 is fixedly connected to the pressing plate 72. The other end of the pressing plate 72 is fitted to the top plate 33. In some embodiments, the locking plate 71 and the pressing plate 72 form an L-shaped structure, and the locking plate 71 is arranged parallel to the support plate 15. After the screening frame 30 is inserted between the two anti-collision plates 20, the locking plate 71 and the pressing plate cooperate to firmly fix the screening frame 30 inside the installation cavity.

[0023] The locking plate 71 and the pressing plate 72 are detachably connected by a second bolt 73. One end of the second bolt 73 passes through the bolt groove on the locking plate 71 and is threadedly connected to the bolt hole on the pressing plate 72, which facilitates the installation and removal of the locking plate 71 and the pressing plate 72 onto the support plate 15.

[0024] The working principle of this utility model is as follows: When in use, the loader drives the bucket to scoop up the sand and gravel to be screened and transports the sand and gravel to the front side of the screen frame 10. The sand and gravel in the bucket roll down from the top of the screening frame 30. During the rolling process, smaller sand and gravel particles pass between adjacent screen rods 40 and fall to the rear side of the screening frame 30, while larger sand and gravel particles roll down along the screen rods 40 to the front side of the screening frame 30. Thus, the gravity of the sand and gravel and the difference in the size of the sand and gravel particles are used to achieve grading. When the screen rod 40 needs to be disassembled, remove the second bolt 73 on the locking plate 71 corresponding to the screening frame 30, so that the screening frame 30 is released from the locking state of the locking mechanism 70. Then the screening frame 30 can be pulled out from the screening area, and the first bolt 35 on the screening frame 30 can be removed. The top plate 33 can be removed from the screening frame 30. At this time, the screen rod 40 can be pulled out from the insertion cavity of the limiting sleeve 34, and the screen rod 40 can be repaired or replaced.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
