[0036] As Figure 7 , Figure 8 , Figure 9The outer side of the square plate 805 is provided with a positioning assembly for adjusting and fixing the position of the positioning ring 819, the positioning assembly comprises positioning plates 818, a rotating cylinder 806 and threaded rods 810, the number of the positioning plates 818 is two groups, the two groups of positioning plates 818 are symmetrically arranged on the upper and lower sides of the fixed cylinder 804, the two positioning plates 818 are fixedly connected through a second connecting rod and the positioning ring 819, the number of the threaded rods 810 is two groups, the two threaded rods 810 penetrate through the square plate 805, the two threaded rods 810 are rotationally connected with the positioning plates 818, the outer side of the two threaded rods 810 is threadedly sleeved with a threaded ring 821, the threaded ring 821 is fixedly connected with the square plate 805, the outer side of the two threaded rods 810 is also slidably sleeved with a limiting cylinder 811, the limiting cylinder 811 is rotationally connected with the square plate 805, the square plate 805 is rotationally connected with an intermediate rod 820, the outer side of the intermediate rod 820 is fixedly sleeved with an intermediate gear 809, the outer side of the limiting cylinder 811 is fixedly sleeved with a transmission gear 812, the transmission gear 812 is engaged with the intermediate gear 809, the outer side of the intermediate rod 820 is also fixedly sleeved with a second bevel gear 808, the outer side of the main shaft 11 is rotationally sleeved with the rotating cylinder 806, the outer side of the rotating cylinder 806 is fixedly sleeved with a first bevel gear 807, the second bevel gear 808 is engaged with the first bevel gear 807;

[0037] Firstly, the cross section of the threaded rod 810 is not circular, and is similar to the cross section of a "drum", the outer sides of the two circular arcs of the threaded rod 810 are provided with threads, before the crushing operation, the rotating cylinder 806 is rotated relative to the main shaft 11, the rotating cylinder 806 drives the intermediate rod 820 to rotate through the first bevel gear 807 and the second bevel gear 808, the intermediate rod 820 drives the limiting cylinder 811 to rotate through the intermediate gear 809 and the transmission gear 812, the limiting cylinder 811 drives the threaded rod 810 to rotate, since the threaded rod 810 is threadedly connected with the threaded ring 821, and the threaded ring 821 is fixedly connected with the square plate 805, therefore, in the process that the threaded rod 810 rotates relative to the square plate 805, the threaded rod 810 also moves relative to the square plate 805, the square plate 805 drives the positioning ring 819 to move through the threaded rod 810, the positioning plate 818 and the second connecting rod, the position of the positioning ring 819 is adjusted, and then the adjustment operation of the minimum length of the crushing rod 801 outside the crushing roller 3 is completed, the length of the crushing rod 801 outside the crushing roller 3 is different, and the crushing promoting effect of the crushing roller 3 is different.

[0038] As Figure 10The outer side of the rotating cylinder 806 is fixedly connected with a fixed plate 813 through two third connecting rods, a plug rod 815 is slidably sleeved in the fixed plate 813, the side, away from the main shaft 11, of the plug rod 815 is fixedly connected with a top plate, the first spring 814 is fixedly connected between the top plate and the fixed plate 813, and the plug rod 815 penetrates through the rotating cylinder 806 and is slidably connected with the rotating cylinder 806; and the outer side of the main shaft 11 is uniformly provided with a plurality of plug slots 816, and the plug rod 815 abuts against the bottom of the plug slot 816.

[0039] Under the action of the plug rod 815 and the plug slot 816, the connection between the rotating cylinder 806 and the main shaft 11 is completed; before the position of the positioning ring 819 is adjusted, the plug rod 815 is moved upward to disconnect the plug rod 815 and the plug slot 816, so that the rotating cylinder 806 and the main shaft 11 are disconnected; after the position adjustment of the positioning ring 819 is completed, the plug rod 815 is loosened, and under the action of the first spring 814, the plug rod 815 reenters the plug slot 816 and abuts against the bottom of the plug slot 816.

[0040] As shown in Figure 11 , the outer side of the shell 1 is provided with a dredging assembly 9 for preventing the feeding hopper 2 from being blocked, the dredging assembly 9 comprises a plurality of dredging rods 94, the plurality of dredging rods 94 penetrate through the side wall of the feeding hopper 2 and are slidably connected with the feeding hopper 2, the side, away from the feeding hopper 2, of the plurality of dredging rods 94 is fixedly connected with a same dredging plate 93, the outer side of the shell 1 is fixedly connected with a clamping plate 91, the upper side of the clamping plate 91 is slidably sleeved with two contact rods 95, the contact rods 95 are oppositely arranged with the conical rod 802, and the two contact rods 95 and the dredging plate 93 are fixedly connected, and the third spring 92 is fixedly connected between the dredging plate 93 and the clamping plate 91.

[0041] Firstly, the contact rod 95 is located on the upper side of the conical rod 802, and in the process that the crushing rod 801 rotates around the main shaft 11 as the center, the uppermost side will lose the limitation of the hydraulic rod 824, so that the crushing rod 801 moves downward, and at the same time, the moving plate 822 and the conical rod 802 also move toward the main shaft 11; before that, the conical rod 802 drives the contact rod 95 to move upward, the contact rod 95 drives the dredging plate 93 and the dredging rod 94 to move upward, and the third spring 92 is stretched; after that, since the contact rod 95 abuts against the conical rod 802, the conical rod 802 that suddenly moves downward will cause the contact rod 95 to move downward, and the contact rod 95 drives the dredging plate 93 and the dredging rod 94 to move downward; in the process that the conical rod 802 rotates around the main shaft 11 as the center, the contact rod 95 is always moved up and down, and finally drives the dredging rod 94 to move up and down, so as to complete the simple dredging operation of the feeding hopper 2 and reduce the possibility of the feeding hopper 2 being blocked.

[0042] As shown in Figure 12The shell 1 is externally provided with a shaking assembly 10 for improving the filtering effect of the filter screen 5, the shaking assembly 10 comprises a plurality of connecting rods 103 fixedly connected to the two sides of the filter screen 5, the plurality of connecting rods 103 are penetrated through the shell 1 and are slidingly connected to the shell 1, the connecting rods 103 on the same side are fixedly connected to the same arc-shaped plate 102, the arc-shaped plate 102 and the shell 1 are fixedly connected to the fourth spring 104, the upper side of one of the arc-shaped plates 102 is fixedly connected to the contact plate 101 through a plurality of fifth connecting rods, the contact plate 101 is located below the conical rod 802 and is matched with the conical rod 802, and the side of the contact plate 101 close to the conical rod 802 is of a circular arc structure;

[0043] Firstly, in the process that the crushing rod 801 rotates around the main shaft 11 as the center, the length of the crushing rod 801 outside the crushing roller 3 becomes maximum under the action of the hydraulic rod 824 before the crushing rod 801 moves to the lowermost side, in this process, the sidewall of the conical rod 802 abuts against the contact plate 101, under the action of the connecting rod 103 and the fourth spring 104, the arc-shaped plate 102 can only slide back and forth relative to the shell 1, in the process that the contact plate 101 abuts against the conical rod 802, similar to the movement principle of the above-mentioned dredging plate 93, when the position of the crushing rod 801 changes, the position of the conical rod 802 also changes, since the conical rod 802 abuts against the contact plate 101, the arc-shaped plate 102 is caused to move relative to the shell 1 and further forms shaking, thereby improving the filtering effect of the filter screen 5;

[0044] The outer wall of the conical rod 802 is coarsely arranged, so that the conical rod 802 can well drive the contact rod 95 and the contact plate 101 to move and increase the friction of the conical rod 802.

[0045] In the application, when it is needed to crush the construction waste, the motor 6 is started, the motor 6 drives the main shaft 11 to rotate through the belt pulley assembly 12, the main shaft 11 rotates through the power gear 4, the rotating directions of the two main shafts 11 are opposite, thereby driving the crushing roller 3 to rotate, the construction waste to be treated is poured into the feeding hopper 2, the construction waste falls on the upper sides of the two crushing rollers 3 and is crushed under the action of the two crushing rollers 3, the fine particles generated are dropped on the lower side of the filter screen 5 into the receiving box 7 below the filter screen 5, and other larger substances are left on the filter screen 5, thereby completing the crushing operation of the construction waste, the above-mentioned are all prior art and will not be described in detail.

[0046] Before the crushing operation, the insertion rod 815 is moved upward to disconnect the insertion rod 815 and the insertion slot 816, thereby disconnecting the rotating cylinder 806 and the main shaft 11, rotating the rotating cylinder 806 relative to the main shaft 11, driving the intermediate rod 820 to rotate through the first bevel gear 807 and the second bevel gear 808, driving the limiting cylinder 811 to rotate through the intermediate gear 809 and the transmission gear 812, and driving the threaded rod 810 to rotate. Since the threaded rod 810 and the threaded ring 821 are threadedly connected, and the threaded ring 821 and the square plate 805 are fixedly connected, the threaded rod 810 will also move relative to the square plate 805 during the rotation of the threaded rod 810 relative to the square plate 805. The threaded rod 810 moves the positioning ring 819 through the positioning plate 818 to adjust the position of the positioning ring 819, thereby completing the adjustment operation of the minimum length of the crushing rod 801 outside the crushing roller 3. The length of the crushing rod 801 outside the crushing roller 3 is different, and the crushing effect on the crushing roller 3 is different. After the position of the positioning ring 819 is adjusted, the insertion rod 815 is loosened, and the insertion rod 815 enters the insertion slot 816 again under the action of the first spring 814 and abuts against the bottom of the insertion slot 816. During the rotation of the main shaft 11 and the crushing roller 3, the main shaft 11 and the crushing roller 3 drive the crushing rod 801 and the square plate 805 to rotate around the main shaft 11. During this process, when the button 817 abuts against the large semicircular plate 803, the hydraulic rod 824 is activated, the moving plate 822 is driven to move by the hydraulic rod 824, the moving rod 825 is driven to move by the moving plate 822, the moving rod 825 abuts against and drives the crushing rod 801 to move, the crushing rod 801 stretches the second spring 826, and the crushing rod 801 drives the intermediate ring 828 to move until the intermediate ring 828 abuts against the fixed ring 827. At this time, the length of the crushing rod 801 outside the crushing roller 3 is the longest, and it is after the crushing rod 801 participates in the crushing work. At this time, the crushing rod 801 abuts against the filter screen 5. Since the two sides of the filter screen 5 are arc-shaped and the large particle substances remaining on the upper side of the filter screen 5 are smaller than the distance between adjacent two crushing rods 801, the substances on the upper side of the filter screen 5 move along the filter screen 5 with the crushing rod 801 until the crushing rod 801 moves out of the filter screen 5. At this time, the substances moved by the crushing rod 801 fall into the receiving box 7 on both sides of the filter screen 5. During the continuous rotation of the crushing rod 801, when the crushing rod 801 moves to the uppermost side, the button 817 and the large semicircular plate 803 are just disconnected, the crushing rod 801 loses the limitation of the hydraulic rod 824, and moves relative to the crushing roller 3 under the action of the second spring 826. The crushing rod 801 drives the intermediate ring 828 to move until the intermediate ring 828 abuts against the positioning ring 819. During the continuous rotation of the crushing rod 801, the crushing rod 801 abuts against the garbage falling between the two crushing rollers 3 to assist the crushing roller 3 in crushing the garbage,The crushing effect of the garbage is improved until the button 817 again abuts against the semicircular plate 803, and the above operation is repeatedly performed. In the process of rotating the crushing rod 801 around the main shaft 11, the crushing rod 801 loses the restriction of the hydraulic rod 824 at the uppermost side, and moves downward, and the moving plate 822 and the tapered rod 802 also move towards the main shaft 11. Before that, the crushing rod 801 drives the contact rod 95 to move upward, and the contact rod 95 drives the dredging plate 93 and the dredging rod 94 to move upward, and the third spring 92 is stretched. After that, the tapered rod 802 abuts against the contact rod 95, and the downward movement of the tapered rod 802 causes the contact rod 95 to move downward, and the contact rod 95 drives the dredging plate 93 and the dredging rod 94 to move downward. In the process of rotating the tapered rod 802 around the main shaft 11, the contact rod 95 moves up and down, and finally drives the dredging rod 94 to move up and down, and the simple dredging operation of the feeding hopper 2 is completed, and the possibility of blocking the feeding hopper 2 is reduced. In the process of rotating the crushing rod 801 around the main shaft 11, the length of the crushing rod 801 outside the crushing roller 3 becomes the maximum under the action of the hydraulic rod 824 before the crushing rod 801 moves to the lowermost side. In this process, the tapered rod 802 abuts against the side wall of the contact plate 101, and the arc-shaped plate 102 can only slide back and forth relative to the shell 1 under the action of the connecting rod 103 and the fourth spring 104. In the process of abutting the contact plate 101 and the tapered rod 802, the movement principle of the above-mentioned dredging plate 93 is similar. When the position of the crushing rod 801 changes, the position of the tapered rod 802 also changes. Since the tapered rod 802 abuts against the contact plate 101, the arc-shaped plate 102 moves relative to the shell 1 and shakes, and finally the filtering effect of the filter screen 5 is improved.
