Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a hammer crusher. Background Technology

[0002] Currently, rotary hammer crushers are commonly used for crushing lumpy raw materials. Material enters the crushing chamber through the feed inlet and falls onto the high-speed rotating hammers. Through the action of the hammers and the impact plates, the material is repeatedly struck and impacted at high frequency in the impact zone, achieving a fine crushing effect. However, while the material is being crushed, the hammers also experience high-frequency impacts. Severe wear on the hammers and impact plates increases the crushing gap between them, resulting in poor crushing efficiency and insufficient output. Conventional crushers cannot adjust the crushing gap between the hammers and impact plates. After a period of use, wear on the impact plates and hammers causes the gap to widen, requiring replacement of the hammers and impact plates. A complete set of hammers needs to be replaced every 3-4 months, resulting in high operating costs.

[0003] In a prior art, a counter-attack plate is hinged to the inner wall of the frame, and a counter-attack block is provided on the counter-attack plate. The middle part of the counter-attack plate is suspended from the frame by a tension spring. One end of the tension spring is hinged to the counter-attack plate. When the counter-attack plate rotates around the hinge point with the frame, the connection part with the tension spring has an arc-shaped motion trajectory, rather than a straight motion in the direction of adjusting the gap. Before and after the counter-attack plate rotates, an angular difference will be generated at the connection point with the tension spring. The axial movement of the tension spring and the connection method of hinged counter-attack plate make the adjustable gap range of the tension spring very small, or even unable to play an adjustment role.

[0004] In another prior art, an ultra-large feed impact crusher uses a similar method to adjust the impact plate as described above. The impact plate is supported by a pressure spring. The illustration shows the impact plate fixedly connected to a spring-loaded pull rod. The specific connection method is not described in the text. The adjustable gap range is very small, or even ineffective for adjustment. Utility Model Content

[0062] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0063] This utility model relates to a hammer crusher for crushing materials. A material box is housed in a shell 1, and a rotor hammer seat 2 forms a hammering area. Multiple hammers 22 are mounted on the rotor hammer seat 2 within the shell 1. A movable support 3 with an impact plate 31 is movably mounted on the shell 1. The distance between the impact plate 31 and the hammers 22 on the movable support 3 can be adjusted via an adjustment mechanism 4. After the impact plate 31 wears down, the crushing gap can be reduced by adjusting the mechanism 4 to improve the crushing effect. A movable mounting component 5 absorbs the angular difference α between the movable support 3 and the adjustment mechanism 4 when the movable support 3 rotates around the hinge, allowing for a larger rotation angle of the movable support 3, thus expanding the range of adjustment for the crushing gap. This solves the problem of poor crushing effect due to the increased crushing gap caused by wear of the impact plate 31 and hammers 22, and the limited range of adjustment for the crushing gap. The structure is simple, easy to use, and has great potential for widespread application.

[0064] A hammer crusher, such as Figures 1-11As shown, the device includes a housing 1, a rotor hammer seat 2, a movable support 3, and an adjusting mechanism 4. The housing 1 has a feed inlet 11 and a discharge outlet 12. The discharge outlet 12 is located at the bottom of the housing 1 and can be located on the bottom or side of the housing 1. The discharge outlet 12 is equipped with a control valve. The rotor hammer seat 2 is rotatably mounted inside the housing 1 and has multiple hammers 22. The movable support 3 is movably mounted on the housing 1 and can be hinged to the housing 1 via a first hinge shaft 32. The movable support 3 has a counter-attack plate 31 on the side near the hammers 22 for receiving the material knocked out by the hammers 22. The adjusting mechanism 4 is mounted on the housing 1 and connected to the movable support 3. It is used to adjust the crushing gap between the movable support 3 and the hammers 22. One end of the movable support 3 is equipped with a movable mounting component 5 that cooperates with the adjusting mechanism 4. The movable mounting component 5 is used to absorb the angle difference α between the movable support 3 and the adjusting mechanism 4 when the movable support 3 rotates around the hinge. When the movable support 3 rotates around the hinge, a rotational angle difference (i.e., rotation angle difference α) also occurs at the connection point with the adjusting mechanism 4. This rotation angle difference α is absorbed by the movable mounting component 5, allowing the adjusting mechanism 4 to control the rotation of the movable support 3 around the hinge, thereby adjusting the aforementioned crushing gap. After a period of use, the hammer 22 and the impact plate 31 wear, causing the crushing gap between the impact plate 31 and the hammer 22 to increase, resulting in poor crushing effect. The adjusting mechanism 4 adjusts the movable support 3 to reduce the crushing gap between the impact plate 31 and the hammer 22, improving the crushing effect.

[0065] Preferably, such as Figure 4 As shown, each set of movable supports 3 is equipped with two adjustment mechanisms 4, that is, the two adjustment mechanisms 4 together adjust one movable support 3.

[0066] Based on the cooperation between the movable support 3 and the adjustment mechanism 4, a movable mounting component 5 is provided, such as... Figures 3-7 As shown, the movable mounting assembly 5 includes a mounting plate 51 on the movable support 3 and a connecting shaft 52 on the adjusting mechanism 4. The mounting plate 51 and the connecting shaft 52 are respectively provided with a mounting slot 511 and a connecting slot 521 located within the mounting slot 511. The width of the connecting slot 521 is greater than the thickness of the mounting plate 51. The connecting slot 521 is preferably an annular groove (not limited to a circle) around the connecting shaft 52, or it can be a groove on one or both sides of the cross-section of the connecting shaft 52. The connecting shaft 52 and the mounting plate 51 are engaged with each other through the connecting slot 521 and the mounting slot 511. The width of the connecting slot 521 being greater than the thickness of the mounting plate 51 provides a movable gap between the connecting slot 521 and the mounting plate 51, enabling a movable connection between the movable support 3 and the adjusting mechanism 4. This allows the movable support 3 to rotate within the connecting slot 521 when rotating around the hinge, absorbing the angle difference α. Figure 7 The dashed line in the middle is Figure 6 A schematic diagram showing the location of mounting plate 51.

[0067] The mounting plate 51 is provided with a mounting slot 511, such asFigures 3-4 As shown in the figure, one end of the mounting slot 511 extends out of the edge of the mounting plate 51. The connecting slot 521 of the connecting shaft 52 can be inserted into the mounting slot 511 from the edge of the mounting plate 51, facilitating the installation of the connecting shaft 52, without the need to set the two parts of the connecting shaft 52 located at both ends of the connecting slot 521 as a split type.

[0068] Based on the cooperation between the movable support 3 and the adjusting mechanism 4, the movable mounting assembly 5 is provided, such as Figure 8 As shown in the figure, the connecting slot 521 is wedge-shaped, one end (the upper end shown in the figure) of the connecting slot 521 near the hinge of the movable support 3 is clamped to the mounting plate 51, and the other end has a space for the mounting plate 51 to move in the connecting slot 521 when the movable support 3 rotates around the hinge, which is used to absorb the rotation angle difference α; when the movable support 3 rotates around the first hinge shaft 32, the mounting plate 51 is clamped at the upper end of the wedge-shaped connecting slot 521, and the lower end of the mounting plate 51 located at the clamping position rotates in the connecting slot 521 (equivalent to rotating around the clamping position) as the movable support 3 rotates, realizing the absorption of the rotation angle difference α; the cross section of the connecting shaft 52 is not limited to a circular shape, and can be a polygonal structure such as a rectangular shape; by clamping the mounting plate 51 at the upper end of the connecting slot 521 and allowing the mounting plate 51 to rotate around the clamping position, the movable support 3 can be fixed when it rotates around the first hinge shaft 32 to a suitable size of the crushing gap.

[0069] In a certain preferred embodiment, as shown in the figure, Figure 8 As shown in the figure, the mounting plate 51 is in surface contact with the slot wall of the connecting slot 521 when it moves in the connecting slot 521 to the point where the crushing gap between the hammer head 2 and the counter-hammer plate 31 is at the end value; the mounting plate 51 is in surface contact with the slot wall of the connecting slot 521 when the crushing gap is at the maximum and / or minimum value.

[0070] Preferably, as shown in the figure, Figure 8 As shown in the figure, one end of the connecting slot 521 clamping the mounting plate 51 is a chamfer structure, and more preferably, the chamfer structure is a circular arc chamfer.

[0071] Based on the connecting slot 521 provided on the connecting shaft 52, as shown in the figure, Figure 9As shown, the connecting shaft 52 is hingedly connected with clamping plates 522 for clamping the mounting plate 51 on both sides of the connecting slot 521. When the movable support 3 rotates, the two clamping plates 522 clamp the mounting plate 51 and rotate around the hinge with the connecting shaft 52 in the connecting slot 521, and the side wall of the connecting slot 521 limits the rotation angle range. Preferably, the clamping plates 522 are in surface contact with the side wall of the connecting slot 521 to limit the rotation angle; the clamping plates 522 can be made of wear-resistant material; the two clamping plates 522 are inserted into the connecting slot 521, and when the adjusting mechanism 3 drives the movable support 3 to rotate around the hinge (the first hinge shaft 32), the two clamping plates 522 clamp the mounting plate 51 to rotate in the connecting slot 521 to absorb the rotation angle difference a. When the side wall of the connecting slot 521 is abutted and limited, the crushing gap range of the adjusting hammer head 22 and the counter-hammer plate 31 can be limited, avoiding the interference between the hammer head 22 and the counter-hammer plate 31 due to the too small crushing gap, and avoiding the poor crushing effect due to the too large crushing gap; the linear clamping of the mounting plate 51 in the connecting slot 521 has a large stress on the clamping position A (as shown in Figure 8 When the mounting plate 51 is replaced due to strain, it is troublesome; by hingedly connecting the two clamping plates 522 on the connecting shaft 52, the linear contact of the connecting slot 521 clamping the mounting plate 51 can be changed to surface contact, the contact area is expanded, the support of the mounting plate 51 is provided by the second hinge shaft 523 hingedly connected between the clamping plate 522 and the connecting shaft 52, which can slow down the strain of the mounting plate 51 and the connecting shaft 52, prolong the service life, and facilitate the maintenance of the clamping plate 522.

[0072] Preferably, one end of the opposite side of the two clamping plates 522 is a circular arc chamfer structure, which facilitates the insertion of the mounting plate 51 into the two clamping plates 522. More preferably, the clamping plate 522 is provided with a first insertion slot for avoiding the part of the connecting shaft 52 in the connecting slot 521.

[0073] In some embodiments, as Figure 5As shown, the adjusting mechanism 4 is axially adjustable on the shell 1; the adjusting mechanism 4 comprises a screw rod 42 threaded on the shell 1 and a screwing piece 41 fixed on one end of the screw rod 42; the other end of the screw rod 42 is connected to the movable support 3 through the movable mounting assembly 5. The axial movement distance of the adjusting mechanism 4 changes the crushing gap of the hammer head 22 and the counterattack paddle 31, which facilitates intuitive understanding and adjustment of the gap size. The screwing piece 41 can be an adjusting wheel disc, which facilitates manual operation and control of the rotation of the screw rod 42; the connecting shaft 52 can be fixedly connected with the screw rod 42 as a whole, and preferably, the connecting shaft 52 is rotatably connected with the screw rod 42, that is, when the screw rod 42 rotates, the connecting shaft 52 is rotatably connected with the screw rod 42 through the clamping mounting plate 51 on one end. In specific use, the shell 1 is provided with a fixed support 43, the fixed support 43 is provided with a threaded hole, and the screw rod 42 is threaded in the threaded hole to realize axial movement. The adjusting mechanism 4 has a simple structure, the screwing piece 41 drives the screw rod 42 to rotate, the screw rod 42 moves relatively on the shell 1 and drives the connecting shaft 52 to move axially, thereby driving the movable support 3 to rotate around the hinge to adjust the size of the crushing gap.
