[0002] Cast iron is an iron alloy material with a high carbon content, which can be cast into a variety of parts and products. Cast iron scrap refers to old castings and iron products that have been eliminated or discarded and can be recycled.

[0003] When recycling cast iron waste, since some cast iron is large in size, it will occupy a large internal space of the melting furnace when recycled and melted, affecting the melting efficiency. Therefore, some cast iron waste needs to be pre-crushed. Conventional crushers use two rotating crushing rollers to crush the cast iron parts. During the stirring process, due to the different shapes of cast iron parts, the more rounded cast iron parts will slip on the two crushing rollers when they are put in, resulting in low crushing efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1-Figure 4 , a pre-treatment crushing device for cast iron waste parts shown in the figure comprises a crusher 1, a conveyor belt 2 is installed on one side of the crusher 1, and the cast iron waste parts are transferred into the crusher 1 through the conveyor belt 2, and also comprises supporting side plates 3 fixed on both sides of the outer frame of the crusher 1, threaded pipes 4 are rotatably installed on the two supporting side plates 3, and a moving seat 5 is installed on the outer side of the threaded pipe 4. The two moving seats 5 are equipped with blocking plates 6 that fit the outer side of the conveyor belt, and the two supporting side plates 3 are equipped with driving members 7 that drive the two threaded pipes 4 to rotate synchronously; and a linkage unit 8 installed in the threaded pipe 4, and a pressing assembly 9 is installed at the bottom of the two linkage units 8, and the cast iron in the crusher 1 is squeezed by the pressing assembly 9;

[0030] In this solution, the threaded tube 4 is driven to rotate by the designed driving member 7, so that the movable seat 5 drives the blocking plate 6 to move up and down to realize the fixed material input. At the same time, the linkage unit 8 is used to drive the pressing assembly 9 to move downward to press the input cast iron parts, assist in crushing, and avoid splashing of fragments.

[0031] For further information, see Figure 7 and Figure 8 The movable seat 5 includes an annular seat 10 sleeved on the outer side of the threaded tube 4, a notch is provided on the annular seat 10, an arc plate 11 is slidably inserted in the notch, a thread groove is engraved on the inner side of the arc plate 11 for docking with the outer thread of the threaded tube 4, a push-opening member 12 fixed to the arc plate 11 is installed on the outer side of the annular seat 10, a limiting plate 13 abutting against the push-opening member 12 is fixed on the supporting side plate 3, a limiting ring 14 is fixed to the bottom of the threaded tube 4, a connecting plate 15 is fixed to the outer side of the annular seat 10, and is fixed to the blocking plate 6 through the connecting plate 15;

[0032] Among them, the push-opening member 12 includes a roller 16 rotatably mounted on the outer end of the arc plate 11, a slide rod 17 is fixed to the outer end of the arc plate 11, the outer sliding sleeve of the slide rod 17 has a docking plate 18 fixed to the outer wall of the annular seat 10, and the slide rod 17 is sleeved with a push-opening spring 19 that resists the docking plate 18 and the arc plate 11.

[0033] The principle of the moving seat 5 driving the blocking plate 6 to move up and down is as follows: first, the roller 16 on the outside of the push-open member 12 is pressed against the limit plate 13, so that the arc plate 11 is pressed against the outside of the threaded tube 4. As the threaded tube 4 rotates, the arc plate 11 moves up and down along the threaded tube 4. When it moves to the lower end of the threaded tube 4, the blocking plate 6 moves to the position as shown in the figure. Figure 3 and Figure 4 In the state shown, the roller 16 is separated from the limit plate 13, and under the action of the push spring 19, the arc plate 11 is away from the threaded tube 4. At this time, the threaded tube 4 continues to rotate and will not drive the arc plate 11 and the annular seat 10 to move up and down accordingly.

[0034] For further information, see Figure 5-Figure 8 as well as Fig. 9 The linkage unit 8 includes a linkage tube 20 rotatably mounted in the threaded tube 4, a screw rod 21 is inserted into the internal thread of the linkage tube 20, the bottom of the screw rod 21 is fixed to the pressing assembly 9, a plurality of mounting holes 22 are opened at equal angles on the threaded tube 4, a plurality of linkage grooves 23 are correspondingly opened on the linkage tube 20, two balls 24 are installed in the mounting holes 22, and one of the balls 24 is adapted to the linkage groove 23;

[0035] The pressing assembly 9 includes a pressing plate 30, on which an inclined plate is provided. One end of the pressing plate 30 is fixed to two screw rods 21, and the other end is fixed to two telescopic rods 31. The two telescopic rods 31 are fixed to the supporting side plate 3, and the inclined plate on the pressing plate 30 is in contact with the outer side of the roller 16.

[0036] The principle of the linkage unit 8 driving the pressing assembly 9 to move up and down is as follows: First, when the moving seat 5 moves to the bottom of the threaded tube 4, the ball 24 in the mounting hole 22 is squeezed. Fig. 9 As shown, the rolling ball 24 abuts against the linkage groove 23, so that the threaded tube 4 and the linkage tube 20 are locked accordingly. The threaded tube 4 continues to rotate, which drives the linkage tube 20 to rotate, so that the screw rod 21 in the linkage tube 20 moves up and down, drives the pressing plate 30 to move downward, and the inclined plate on the pressing plate 30 moves downward accordingly. In the absence of the limiting plate 13 and the limiting position of the inclined plate, the push-opening member 12 extends outward;

[0037] By moving the pressing plate 30 downward, the cast iron parts are squeezed to achieve a better crushing effect and avoid debris splashing. As the driving member 7 is reversed, the screw rod 21 moves upward accordingly, thereby causing the pressing plate 30 to rise accordingly until the inclined plate on the pressing plate 30 abuts against the push-opening member 12, squeezing the roller 16, so that the arc plate 11 and the threaded tube 4 are docked. At this time, the moving seat 5 will start to move upward with the reversed threaded tube 4 to open the blocking plate 6.

[0038] It should also be noted that in order to ensure stable extrusion of the cast iron parts, two plug rods 32 are slidably inserted on the pressing plate 30, and an extrusion plate 33 is fixed to the bottom of the two plug rods 32. An extrusion spring 34 that is against the extrusion plate 33 and the pressing plate 30 is sleeved on the outside of the two plug rods 32. At the same time, the extrusion plate 33 is made of rubber material.

[0039] For further information, see Figure 2 - Figure 6 The driving member 7 includes a synchronous gear 35 fixed to the outside of the two threaded tubes 4, and a toothed belt 36 is meshed on the outside of the two synchronous gears 35. A transmission gear 37 is fixed to the outside of one of the threaded tubes 4. A driving motor 38 is fixed to the top of one of the supporting side plates 3 through a motor frame, and a driving gear 39 meshing with the transmission gear 37 is fixed to the output end of the driving motor 38;

[0040] By driving the motor 38 to rotate, the driving gear 39 and the transmission gear 37 are driven to rotate accordingly, so that one of the threaded tubes 4 is rotated. Under the action of the toothed belt 36 and the synchronous gear 35, the two threaded tubes 4 are synchronously driven. The forward and reverse rotation of the driving motor 38 drives the forward and reverse rotation of the threaded tube 4.

[0041] In this solution, the cast iron parts are subjected to a stable crushing step without debris splashing;

[0042] First, the cast iron pieces are transported in sequence by the conveyor belt 2, and are first blocked by the blocking plate 6. When a certain amount of cast iron pieces are gathered, they are opened and put into the crusher 1 for quantitative feeding;

[0043] After the cast iron is put in, the blocking plate 6 moves down again by the rotation of the threaded tube 4. At this time, the rolling ball 24 in the threaded tube 4 is connected with the linkage groove 23 on the linkage tube 20, thereby driving the linkage tube 20 to rotate, so that the pressing plate 30 moves down, and the push-opening member 12 is opened, and the arc plate 11 is separated from the threaded tube 4.

[0044] After the pressing plate 30 squeezes the cast iron part, the threaded tube 4 is reversed, so that the pressing plate 30 moves up and resets, and the inclined plate on the pressing plate 30 abuts against the push-opening member 12 again, so that the push-opening member 12 retreats and resets;

[0045] After the push-opening member 12 is reset, the arc plate 11 is again fitted with the threaded tube 4. As the threaded tube 4 reverses, the movable seat 5 and the blocking plate 6 begin to move upward to discharge the material again. This reciprocating process assists in crushing and prevents the fragments from splashing.

[0046] Example 2: Please refer to Figure 7 and Figure 8 as well as Fig. 9 This embodiment further explains the first embodiment, and the difference lies in the optimization of the structure of the annular seat 10.

[0047] Specifically, a buffer spring 25 is fixed to the bottom of the annular seat 10, a contact ring 26 is sleeved on the outer side of the threaded tube 4, the buffer spring 25 is fixed to the contact ring 26, and a chamfer is provided on the inner side of the contact ring 26;

[0048] In this solution, after the movable seat 5 contacts the ball 24, the push-opening member 12 on the movable seat 5 has not been pushed open and needs to continue to move downward during the downward movement of the pressing plate 30. Therefore, the designed buffer spring 25 is used to allow the movable seat 5 to continue to move downward for a short distance.

[0049] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further illustrates other embodiments, and the difference lies in the optimization of the structure of the limiting plate 13.

[0050] Specifically, a recess 27 is provided at the bottom of the limit plate 13, a sliding column is fixed in the recess 27, a fitting plate 28 is slidably inserted at the bottom of the sliding column, and a push spring 29 is sleeved on the outside of the sliding column and fits with the fitting plate 28 and the inner wall of the recess 27. The fitting plate 28 is designed to extend and fit with the inclined plate on the pressing plate 30, so that the roller 16 will not be pushed outward when it moves upward. With the help of the fitting plate 28, the roller 16 can be stably fitted with the outer side of the limit plate 13.
