Description

Technical Field

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

[0002] Hammer mills are one of the key pieces of equipment in the feed industry. During feed processing, it is necessary to crush raw materials such as corn and soybean meal. Existing hammer mills typically include a casing, a rotor assembly, and a grate plate located below the rotor. The working principle is as follows: high-speed rotating hammers impact and crush the input materials. The crushed material particles are discharged through the screen holes set on the grate plate under the action of the hammers and their own gravity. However, the larger unqualified materials are blocked above the grate plate and continue to be impacted by the hammers until they are crushed to a qualified degree.

[0003] However, in practical applications, relying on fixed grate plates for screening and discharge has obvious drawbacks. The grate plate is in a fixed and static state, and its screening depends on the material's own weight and the airflow generated by the rotation of the hammer. However, for feed raw materials with high oil content and high fiber content, the material tends to accumulate on the surface of the grate plate. As the crushing operation continues, the qualified material is difficult to pass through the screen holes in a timely and smooth manner, resulting in material accumulation and screen blockage, which seriously affects the material crushing efficiency.

[0004] Therefore, this utility model proposes a high-efficiency hammer crusher to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency hammer mill to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency hammer mill includes a casing, a crushing chamber disposed within the casing, a feed inlet communicating with the crushing chamber, a rotor disposed within the crushing chamber, and a first drive assembly for driving the rotor to rotate. The crushing chamber includes a base plate rotatably embedded on one side of the casing and two first arc-shaped plates coaxially fixed on the base plate. The sides of the two first arc-shaped plates away from the base plate are in contact with the inner wall of the casing, and a feed inlet is formed between the upper sides of the two first arc-shaped plates. The crushing chamber also includes a second arc-shaped plate fixedly disposed within the casing for closing the feed inlet. The feed inlet is disposed on the second arc-shaped plate, and the second arc-shaped plate is slidably engaged with the two first arc-shaped plates. A grate plate is provided between the lower sides of the two first arc-shaped plates. The hammer mill also includes a second drive assembly for driving the crushing chamber to reciprocate.

[0007] In one alternative: the side of the second arc-shaped plate closest to the substrate is in contact with and bonded to the substrate, and both axial sides of the grate plate are in contact with and bonded to the inner wall of the housing and the substrate, respectively.

[0008] In one alternative: adhesive strips are provided on the side of the second arc-shaped plate that contacts and adheres to the substrate, as well as on both sides of the axial direction of the grate plate, and an adhesive pad is provided between the second arc-shaped plate and the first arc-shaped plate.

[0009] In one alternative embodiment, the second drive assembly includes an arc-shaped rack fixed on the substrate and coaxial with the substrate, a gear meshing with the arc-shaped rack, and a drive member for driving the gear to rotate.

[0010] In one alternative: the grate plate is detachably disposed between the lower sides of the two first arc-shaped plates, and the grate plate is provided with a variety of different specifications to meet the needs of crushing and screening different materials.

[0011] In one alternative: the machine housing has an operating port on one side for replacing the grate plate, and the operating port is equipped with a baffle door that can be opened and closed.

[0012] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: Feed ingredients are fed evenly and continuously into the crushing chamber through the feeding port. The rotor is driven to rotate by the first drive component to crush the material. The crushing chamber is driven to reciprocate at a set angle by the second drive component, which in turn drives the two first arc plates and the grate plate to reciprocate accordingly. Under the action of the material's own gravity, the material on the grate plate is in a reciprocating surging state, thereby achieving the effect of screening. This promotes the efficient discharge of qualified crushed material, avoids material accumulation and blockage, and ensures that the crushing work is carried out smoothly and efficiently.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Please see Figures 1-4 A high-efficiency hammer mill includes a housing 1, a crushing chamber 2 disposed within the housing 1, a feeding port 5 communicating with the crushing chamber 2, a rotor 3 disposed within the crushing chamber 2, and a first drive assembly 4 for driving the rotor 3 to rotate. The crushing chamber 2 includes a base plate 201 rotatably embedded on one side of the housing 1 and two first arc-shaped plates 202 coaxially fixed on the base plate 201. The sides of the two first arc-shaped plates 202 away from the base plate 201 are in contact with and fitted against the inner wall of the housing 1, and a material discharge port 205 is formed between the upper sides of the two first arc-shaped plates 202. The crushing chamber 2 also includes a component fixedly disposed within the housing 1 for sealing the material discharge port 205. The second arc-shaped plate 203, the feeding port 5 is provided on the second arc-shaped plate 203, and the second arc-shaped plate 203 is in sliding fit with the two first arc-shaped plates 202 (the sliding fit can be achieved by setting a boss-slide groove structure, or the second arc-shaped plate 203 and the two first arc-shaped plates 202 can slide relative to each other in contact and contact, which is not limited here. In addition, the second arc-shaped plate 203 and the two first arc-shaped plates 202 are coaxially arranged). A grate plate 204 is provided between the lower sides of the two first arc-shaped plates 202. The hammer crusher also includes a second drive component 6 for driving the crushing chamber 2 to reciprocate.

[0023] It should be noted that the rotor 3 includes a main shaft (rotatably mounted on the side opposite to the housing 1 and the base plate 201), multiple hammer discs that are parallel and coaxially arranged on the main shaft at certain intervals, multiple hammer shafts that are arranged circumferentially through the multiple hammer discs, and multiple hammer heads that are hinged and suspended on the hammer shafts; the first drive assembly 4 includes a main motor (such as a three-phase AC asynchronous motor), a transmission structure (such as a V-belt and pulley, or a coupling), and a bearing seat and bearings that support and ensure the stable rotation of the rotor 3. The above is the prior art, and the specific component composition and the connection relationship between the components will not be described in detail here.

[0024] Feed raw materials are fed evenly and continuously into the crushing chamber 2 through the feeding port 5 via equipment such as belt conveyors and screw conveyors. The rotor 3 is driven to rotate by the first drive component 4 to crush the material. The crushing chamber 2 is driven to reciprocate and deflect by the second drive component 6 at a set angle (the set angle satisfies that the lower side of the feeding port 5 is always within the range of the discharge port 205). This causes the two first arc plates 202 and the grate plate 204 to reciprocate and deflect accordingly. Under the action of the material's own gravity, the material on the grate plate 204 is in a reciprocating surging state, thereby achieving the effect of screening. This promotes the efficient discharge of crushed and qualified material, avoids the phenomenon of material accumulation and blockage, and ensures that the crushing work is carried out smoothly and efficiently.

[0025] Furthermore, the second arc-shaped plate 203 has one side close to the substrate 201 in contact with the substrate 201 (the other side is closed and connected to the inner wall of the housing 1). The two axial sides of the grate plate 204 are respectively in contact with the inner wall of the housing 1 and the substrate 201. Adhesive strips (not shown in the figure) are provided on the side of the second arc-shaped plate 203 in contact with the substrate 201 and on both axial sides of the grate plate 204. By providing adhesive strips, the contact between the side of the second arc-shaped plate 203 and the substrate 201, and between the two axial sides of the grate plate 204 and the inner wall of the housing 1 and the substrate 201, is soft and elastic, satisfying the sealing requirements (preventing material leakage) and preventing scratches on the substrate 201 and the inner wall of the housing 1 during the reciprocating rotation of the crushing chamber 2. An adhesive pad (not shown in the figure) is provided between the second arc-shaped plate 203 and the first arc-shaped plate 202. Figure 3 As shown in the diagram, the rubber pad can be placed on the inner side of the second arc plate 203 or on the outer side of the two first arc plates 202, so that the second arc plate 203 and the first arc plate 202 are in soft and elastic contact, which plays a role in sealing and sliding protection.

[0026] Furthermore, the lower opening of the casing 1 is used for material discharge. In actual application, the hammer crusher can be combined with a bracket or support platform, or symmetrical support legs can be set on the casing 1 to make the lower side of the casing 1 a certain height off the ground, so that the material can be discharged smoothly.

[0027] Furthermore, the exterior of the housing 1 is also provided with a control panel for operating the hammer crusher.

[0028] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the second driving component 6 includes an arc-shaped rack 601 fixed on the base plate 201 and coaxial with the base plate 201, a gear 602 meshing with the arc-shaped rack 601, and a driving component 503 for driving the gear 602 to rotate (the driving component 503 is a high-torque servo motor, high-torque geared motor, etc. in the prior art). The output shaft of the driving component 503 rotates alternately in the forward and reverse directions, driving the gear 602 to rotate alternately in the forward and reverse directions accordingly. Under the meshing transmission action of the arc-shaped rack 601 and the gear 602, the base plate 201 is driven to rotate alternately in the forward and reverse directions, that is, the two first arc-shaped plates 202 and the grate plate 204 are driven to reciprocate and deflect accordingly, so that the material is in a reciprocating surging state, achieving the effect of screening, and promoting the efficient discharge of crushed qualified material.

[0029] Please see Figure 4 In one embodiment of this utility model, the grate plate 204 is detachably disposed between the lower sides of the two first arc-shaped plates 202, and the grate plate 204 is provided with a variety of different specifications to meet the needs of crushing and screening different materials. According to the type of material to be crushed and the actual crushing requirements, the grate plate 204 of the corresponding specifications is selected for installation and use. The housing 1 has an operating port 607 on one side for replacing the grate plate 204. The operating port 607 is equipped with a baffle door 8 that can be opened and closed. When it is necessary to replace the grate plate 204, the baffle door 8 is opened, and the replacement tools and the hands of the workers can enter through the operating port 607 to carry out the operation. It should be noted that the grate plate 204 is detachable and installable by means of bolts, pins, etc., which is the existing technology and will not be described in detail here.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
