Technical Field
[0001] This utility model relates to the field of crusher design, and in particular to the field of crusher feeding rotation structure technology, specifically a crusher feeding rotation device. Background Art
[0002] Hammer mills are widely used in industries such as feed, food, chemical, and pharmaceutical. A hammer mill mainly consists of a feeder and a grinding chamber. When the material enters the grinding chamber, it impacts the working surface of the hammers at high speed, thereby gradually crushing it to the required particle size and allowing it to pass through the sieve holes.
[0003] The feeding device of a hammer mill is an important component of the mill. The current mainstream method is manual control. The manual control method mainly includes a connecting shaft welded to the feeding plate, a stop block welded between the two plates at the bottom of the feeding plate, and a feeding guide rod inserted into the bottom of the stop block. By rotating the handle, the feeding position of the material entering the crushing chamber of the hammer mill is changed. However, the existing manual control is often a cumbersome operation, prone to operational errors, and thus cannot change the feeding position of the material in time or is not properly adjusted. For example, after the feeding plate is adjusted, if the top does not fit against the side wall of the feeding port, the material will enter the crushing chamber from both sides of the feeding port, resulting in the processed material not achieving the expected effect.

[0040] This utility model proposes a feeding rotation device for a crusher, which is used in the improvement of the crusher process. This utility model does not limit the type and specifications of the crusher, but the structure of the guide plate 2, safety plug 3, and pneumatic deflection module 4 is particularly suitable for the structure of manually controlling the deflection direction of the guide plate 2 in the improvement of the crusher.
[0041] In general, the feed rotation device for the crusher proposed in this utility model mainly includes: a guide plate 2, a safety insert 3, and a pneumatic deflection module 4. Its structure is particularly suitable for improving the manually controlled guide plate 2 in crushers. See also... Figure 1 It shows the structure of the guide plate 2, safety plug 3, and pneumatic deflection module 4, which is particularly suitable for improving the arrangement of the manually controlled guide plate 2 in a crusher.
[0042] Example 1: When using the feed rotation device for the crusher proposed in this utility model, if the raw material entering the crusher is of high quality, has few impurities, and is relatively loose, the safety plug 3 can be omitted. The cylinder 42 in the pneumatic deflection module 4 drives the feed guide rod 44 to swing to the left or right, which drives the quadrilateral rotating rod 47 to rotate, causing the top of the guide plate 2 to deflect to the left or right side of the feed inlet 11. When the feed guide rod 44 swings, the trigger block 46 is controlled to contact the left or right contact switch 51. The contact switch 51 is different, which controls the clockwise or counterclockwise rotation of the hammer in the crusher.
[0043] Example 2: When using the feed rotation device for the crusher proposed in this utility model, if the raw material entering the crusher contains a lot of impurities and is mostly lumpy, the safety plug 3 needs to be removed before adjustment. Then, the cylinder 42 in the pneumatic deflection module 4 drives the feed guide rod 44 to swing to the left or right, which drives the quadrilateral rotating rod 47 to rotate, causing the top of the guide plate 2 to deflect to the left or right side of the feed inlet 11. After the pneumatic deflection module 4 drives the guide plate 2 to adjust, the safety plug 3 is reinstalled.
[0044] The aforementioned guide plate 2 is disposed at the top of the feed inlet 11. The guide plate 2 includes: a hollow round tube 21, a feed plate 22, a connecting plate 23, and a fixing block 24. The hollow round tube 21 contacts the front or rear side wall of the top of the feed inlet 11. The arc shape at the top of the hollow round tube 21 can prevent material accumulation. The top of the feed plate 22 is welded to the left and right sides of the hollow round tube 21. The bottom of the feed plate 22 extends downward at an angle. The connecting plate 23 is welded to the bottom of the feed plate 22. The fixing block 24 is bolted to the bottom of the connecting plate 23 on the side that is close to each other. There is a rotating shaft cavity 25 between the fixing block 24 and the connecting plate 23.
[0045] The aforementioned safety insert 3 is installed on the left or right side of the top of the two crushing chamber side plates 1. The bottom of the safety insert 3 passes through the crushing chamber side plate 1 and connects to the top of the guide plate 2. The safety insert 3 includes a hexagonal screw 31 and a hexagonal nut 32. One side of the hexagonal screw 31 is located on the left or right side of the top of the two crushing chamber side plates 1. The other side of the hexagonal screw 31 passes through the crushing chamber side plate 1 and the guide plate 2 and is installed in the center of the hollow round tube 21. The hexagonal nut 32 is fitted onto the hexagonal screw 31 and the center of the tube. The safety plug 3 is placed on the side of the crushing chamber side plate 1 away from the guide plate 2. One end of the hexagonal screw 31 contacts the crushing chamber side plate 1. The safety plug 3 supports the guide plate 2. The safety plug 3 can improve the stability of the guide plate 2 under high load feeding conditions of the hammer mill and prevent the guide plate 2 from shifting position. Whether the safety plug 3 needs to be installed can be selected according to the working environment and material condition. In addition, if the hammer mill needs to be transported after the entire machine is produced, installing the safety plug 3 can protect the guide plate 2 and prevent it from falling off and deforming during transportation.
[0046] The aforementioned pneumatic deflection module 4 is bolted to one side of the crushing chamber side plate 1. The top of the pneumatic deflection module 4 passes through the crushing chamber side plate 1 and is secured to the bottom of the guide plate 2. The pneumatic deflection module 4 includes: a cylinder mounting bracket 41, a cylinder 42, a feed guide rod 44, a quadrilateral rotating rod 47, and a bushing 48. The cylinder mounting bracket 41 is bolted to the side of the crushing chamber side plate 1 away from the guide plate 2. One side of the cylinder 42 is bolted to the cylinder mounting bracket 41. A U-shaped block 43 is bolted to the top of the cylinder arm in the cylinder 42. The bottom of the feed guide rod 44 is secured within the U-shaped block 43. A pin 45 passes through the bottom of the feed guide rod 44, with two pins 45 passing through the left and right side walls of the U-shaped block 43. The feed guide rod 44 swings back and forth between the contact switches 51 around the pin 45 as its rotation center. Shaft 45 enables the feed guide rod 44 to swing and adjust. Trigger blocks 46 are provided on the top left and right sides of the feed guide rod 44. The trigger blocks 46 contact the switch 51 to send a forward or reverse signal to the hammer motor in the crushing chamber. One side of the quadrilateral rotating rod 47 passes through the top of the feed guide rod 44, and the other side of the quadrilateral rotating rod 47 passes through the side plate 1 of the crushing chamber and enters the rotating shaft cavity 25, exiting from the side plate 1 of the crushing chamber away from the cylinder fixing frame 41. The rotation of the quadrilateral rotating rod 47 drives the guide plate 2 to swing. A bushing 48 is sleeved on the other side of the quadrilateral rotating rod 47. The bottom of the bushing 48 passes through the side plate 1 of the crushing chamber and is located between the quadrilateral rotating rod 47 and the side plate 1 of the crushing chamber. Because the quadrilateral rotating rod 47 is quadrilateral in shape, the bushing can effectively prevent the quadrilateral rotating rod 47 from colliding with the side plate 1 of the crushing chamber and improve the stability during swinging.
[0047] It should also be noted that a switch frame 5 is bolted to the center of the top of the side plate 1 of the crushing chamber away from the guide plate 2. Contact switches 51 are installed on the left and right sides of the bottom of the switch frame 5. One side of the contact switch 51 contacts the trigger block 46 on the left or right side of the top of the feed guide rod 44. The contact switch 51 controls the forward or reverse rotation of the hammer motor in the crushing chamber. Depending on the raw material, the direction of the guide plate 2 is changed to control the feeding position of the raw material entering the crushing chamber and at the same time change the rotation direction of the hammer motor to prevent technicians from forgetting to operate.
[0048] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
