[0025] Specifically, the pusher assembly 4 includes an L-shaped rod 41, a mounting plate 42, a pusher plate 43 and a fixing member 44. The L-shaped rod 41 is arranged inside the equipment body 1 and above the selection mechanism 2. The fixing member 44 is arranged between the L-shaped rod 41 and the equipment body 1. One end of the L-shaped rod 41 is connected to the mounting plate 42. The side of the mounting plate 42 away from the L-shaped rod 41 is connected to the pusher plate 43.

[0026] By adopting the above technical solution, when it is necessary to process the rounded large-particle coarse aggregate above the selection mechanism 2, first release the fixing effect of the fixing part 44 on the L-shaped rod 41, then hold the L-shaped rod 41 to drive the mounting plate 42 to move, and the movement of the mounting plate 42 drives the push plate 43 to move along the selection mechanism 2. During the movement of the push plate 43, the rounded large-particle coarse aggregate on the selection mechanism 2 can be pushed to perform the discharging operation, which is convenient for the operator to collect the rounded large-particle coarse aggregate.

[0027] Specifically, the fixing member 44 includes a fixing screw 441, a through hole 442 and a threaded barrel 443. The fixing screw 441 is connected to the side wall of the L-shaped rod 41. The through hole 442 is provided on the device body 1 at a position corresponding to the fixing screw 441. One end of the fixing screw 441 is connected to the threaded barrel 443.

[0028] By adopting the above technical solution, the L-shaped rod 41 is moved to fit the side wall of the equipment body 1, and then the fixing screw 441 observes the through hole 442, and then the threaded tube 443 is rotated and screwed onto the fixing screw 441. Under the action of the fixing screw 441 and the threaded tube 443, the L-shaped rod 41 can be fixed to ensure the stability of the placement of the L-shaped rod 41.

[0029] Specifically, the device body 1 and the side wall of the threaded cylinder 443 are both connected with connecting columns, and an elastic rope is connected between the two connecting columns.

[0030] By adopting the above technical solution, after the threaded barrel 443 is rotated and removed from the fixing screw 441, the threaded barrel 443 can be suspended under the action of the elastic rope to prevent the threaded barrel 443 from being lost.

When it is necessary to collect the rounded large-particle coarse aggregate on the selection mechanism 2, the threaded cylinder 443 is rotated and removed from the fixed screw 441, and then the L-shaped rod 41 is moved by hand. The movement of the L-shaped rod 41 drives the mounting plate 42 and the fixed screw 441 to move, and the movement of the mounting plate 42 drives the push plate 43 to move along the selection mechanism 2.

[0032] Example 2

[0033] The present embodiment is different from the embodiment 1 in that: the placement component 3 includes a bearing plate 31, an end block 32, a support block 36, a second spring 37 and a rotating screw 38; the bearing plate 31 is connected to one side of the device body 1; the end blocks 32 are connected to the side walls of the device body 1 and at both ends of the bearing plate 31; the support block 36 is inserted into the end block 32; the second spring 37 is connected between the end block 32 and the support block 36; and the rotating screw 38 is connected to one end of the end block 32.

[0034] Specifically, the placement assembly 3 further includes a plug-in rod 33, an external connection tube 34 and a first spring 35. Both ends of the device body 1 are connected to the external connection tube 34. The plug-in rod 33 is plugged into the internal part of the external connection tube 34. The first spring 35 is connected between the plug-in rod 33 and the external connection tube 34.

[0035] By adopting the above technical solution, when it is necessary to rotate and open the supporting plate 31, the plug-in rod 33 is pulled toward the periphery of the external tube 34, and the plug-in rod 33 moves to squeeze the first spring 35. When the plug-in rod 33 is away from the supporting plate 31, the supporting plate 31 is rotated again to be retracted into the inside of the device body 1, and then the plug-in rod 33 is released. The first spring 35 loses the external force and returns to its original state, driving the plug-in rod 33 to move and be plugged into the inside of the supporting plate 31. Under the action of the plug-in rod 33, the supporting plate 31 can be plugged and fixed to ensure the stability of the placement of the supporting plate 31.

[0036] When the present embodiment is used and it is necessary to collect the rounded large-particle coarse aggregate on the selection mechanism 2, firstly rotate the rotating screw 38 to rotate and move along the end block 32. The movement of the rotating screw 38 drives the support block 36 to move. The movement of the support block 36 drives the second spring 37 to stretch. When the support block 36 is away from the end block 32, the plug-in rod 33 is pulled toward the periphery of the external connection tube 34. The plug-in rod 33 moves to squeeze the first spring 35. When the plug-in rod 33 is away from the supporting plate 31, the supporting plate 31 is rotated again to overlap the support block 36. Then, the collecting container is placed on the supporting plate 31 and the collecting container is made to fit the end of the selection mechanism 2, so that the operator can place the collecting container conveniently and collect the rounded large-particle coarse aggregate on the selection mechanism 2 conveniently.

[0037] The structure and principle of the selection mechanism 2 composed of the first selection sieve plate, the second selection sieve plate, the first sieve hole, the second sieve hole, the mounting strip plate, the slot plate, the threaded pin shaft, the pin hole, and the slot in the utility model have been disclosed in a coarse aggregate selection device based on concrete production disclosed in Chinese patent application No. 202122365462.1. Its working principle is: the first selection sieve plate and the second selection sieve plate are arranged parallel to each other on the inner side of the equipment body 1, and the first selection sieve plate is provided with a plurality of first sieve holes, and the second selection sieve plate is provided with a plurality of first sieve holes. A plurality of second sieve holes, the first sieve hole and the second sieve hole are equal in size and shape, the first sieve hole and the second sieve hole are staggered in the vertical direction, a slot plate is fixedly connected to the inner wall of one side of the equipment body 1, a pair of slots are provided on the slot plate which can respectively engage with the first selected sieve plate and the second selected sieve plate, one end of the second selected sieve plate is fixedly connected to the inner wall of the equipment body 1, the other end of the second selected sieve plate is fixedly engaged with one of the slots, one end of the first selected sieve plate is movably engaged with the other slot, and the other end of the first selected sieve plate movably penetrates the equipment body 1. The side plate of the main body 1 of the equipment is provided, and a mounting strip is fixedly connected to the outside of the side plate of the main body 1 and located above the first selected screen plate, and pin holes are provided on the mounting strip and the first selected screen plate, and threaded pin shafts are connected inside the pin holes. When in use, the first screen hole and the second screen hole on the first selected screen plate and the second selected screen plate are offset from each other in the vertical direction. When screening materials, slender coarse aggregates will be blocked between the first screen hole and the second screen hole, and rounded small-particle coarse aggregates will fall into the main body 1 after passing through the first screen hole and the second screen hole in turn. After the collection of the rounded small particles of coarse aggregate is completed, the door body 5 is opened, the small particle collection box 6 is taken out from the inside of the equipment main body 1, and then the slender coarse aggregate collection box 6 is inserted into the inside of the equipment main body 1, and then the first selection screen plate is pushed horizontally, so that the first selection screen plate and the second selection screen plate are in a vertically aligned position relationship, and the first sieve hole and the second sieve hole are aligned with each other in the vertical direction, and the slender coarse aggregate can fall into the slender coarse aggregate collection box 6, leaving only the rounded large particles of coarse aggregate on the first selection screen plate.

[0038] Working principle and use process of the utility model: in the construction concrete production process of the utility model, when it is necessary to select the coarse aggregate, the coarse aggregate is injected into the selection mechanism 2, and the selection mechanism 2 is used to select the coarse aggregate. During the selection process, the slender coarse aggregate and the rounded small-particle coarse aggregate fall into the collecting box 6 for collection, and then the door 5 is opened to take out the collecting box 6 from the inside of the equipment body 1. The rounded large-particle coarse aggregate is blocked on the selection mechanism 2. When it is necessary to collect the rounded large-particle coarse aggregate on the selection mechanism 2, first rotate the rotating screw 38 to rotate and move along the end block 32. The movement of the rotating screw 38 drives the support block 36 to move. The movement of the support block 36 drives the second spring 37 to stretch. When the support block 36 is away from the end block 32, it is pulled toward the periphery of the external connection tube 34. The plug-in rod 33 moves to squeeze the first spring 35. When the plug-in rod 33 is away from the supporting plate 31, the supporting plate 31 is rotated to overlap the support block 36, and then the collecting container is placed on the supporting plate 31, and the collecting container is made to fit the end of the selection mechanism 2, so that the operator can place the collecting container, and then collect the rounded large-grained coarse aggregate on the selection mechanism 2. After the threaded cylinder 443 is removed from the fixed screw 441 by rotation, the L-shaped rod 41 is held and moved. The movement of the L-shaped rod 41 drives the mounting plate 42 and the fixed screw 441 to move. The movement of the mounting plate 42 drives the push plate 43 to move along the selection mechanism 2. During the movement of the push plate 43, the rounded large-grained coarse aggregate on the selection mechanism 2 can be pushed for discharging, and the rounded large-grained coarse aggregate falls into the collection container for collection.
