Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of crushers and specifically provides a hammer crusher. Background Art
[0002] With the development of material crushing technology, crushers that can crush organic materials (such as straw and hay) into particles are gradually applied to the field of material crushing.
[0003] In the related technical scheme, the crusher includes a barrel-shaped shell, which is a crushing barrel. The upper end of the crushing barrel is open to add materials, and the bottom wall of the crushing barrel is provided with a discharge port to discharge the crushed materials. A crushing assembly is rotatably installed in the inner cavity of the crushing barrel, and the crushing assembly has multiple crushing knives. After the material is added to the crushing barrel, the rotation of the crushing assembly will cause the crushing knives to cut the material at high speed, and the cut material will fall to the discharge port for discharge.
[0004] The inventors understand that in the above technical solution, a large gap needs to be reserved between the crushing knife and the inside of the crushing barrel to prevent the crushing knife from being stuck or damaged due to the material entangled between the inner wall of the crushing barrel and the crushing knife. However, the large gap between the inner wall of the crushing barrel and the crushing knife will make the material in the gap unable to be fully crushed, resulting in uneven crushing of some materials.
[0005] In addition, the discharge port is arranged near the edge of the lower end surface of the bottom wall of the crushing barrel. When the gap between the crushing knife and the inner wall of the crushing barrel is large, it is not convenient for the crushing assembly to push the crushed material to the discharge port by rotating. Utility Model Content
[0006] The purpose of the utility model is to provide a hammer crusher which can solve at least one of the above technical problems.
[0007] In order to solve the above-mentioned problems in the prior art, one or more embodiments of the utility model provide a hammer crusher, including a frame, a vertical crushing barrel is arranged on the frame, the upper part of the crushing barrel has a feed port, the lower bottom surface of the crushing barrel has a discharge port near its own edge, the crushing barrel has a crushing disk coaxial with the crushing barrel, the crushing disk is driven by a power assembly to rotate around its own axis, the upper surface of the crushing disk has a plurality of crushing knives, the outer peripheral edge of the crushing disk is evenly installed with a plurality of crushing hammers, the crushing hammers are rotatably connected to the crushing disk and the rotation axes of the two are parallel to the rotation axis of the crushing disk.
[0008] Beneficial effects of one or more of the above technical solutions:
[0009] In this solution, a crushing barrel coaxial with the crushing barrel is provided inside the crushing barrel, a plurality of crushing knives are provided on the upper surface of the crushing disk, a plurality of crushing hammers are evenly installed on the outer peripheral edge of the crushing disk, and the crushing hammers are rotatably connected to the crushing disk, and the rotation axes of the two are parallel to the rotation axis of the crushing disk. In this arrangement, the crushing hammers rotatably connected to the crushing disk body can fill the gap between the crushing disk and the inner wall of the crushing barrel when the crushing disk rotates, and can prevent the crushing hammers from being stuck by the material by rotating between themselves and the crushing disk.
[0010] In this solution, the breaker hammer installed on the edge of the crushing disk can also play the role of crushing materials, and the breaker hammer can lift the materials that fall into the gap between the crushing disk and the crushing barrel to the crushing disk position, increasing the contact time between the materials and the crushing blades in the crushing disk, making the materials crushed more evenly.
[0011] In addition, in this scheme, the discharge port is arranged on the lower bottom surface of the crushing barrel close to its own edge. When there is a gap between the crushing disk and the inner wall of the crushing barrel and the crushed material cannot be pushed to the discharge port, it is convenient to use the crushing hammer to transport the material along the circumference of the crushing barrel to the discharge port for discharge.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0023] like Figure 1-Figure 6 As shown, a hammer crusher provided in this embodiment includes a frame 3, a vertical crushing barrel 1 is provided on the frame 3, the crushing barrel 1 has a feed port 102 on the upper portion, the lower bottom surface of the crushing barrel 1 has a discharge port near its own edge, the crushing barrel 1 has a crushing disk 5 coaxial with the crushing barrel 1, the crushing disk 5 is driven by a power assembly to rotate around its own axis, the upper surface of the crushing disk 5 has a plurality of crushing knives, the outer peripheral edge of the crushing disk 5 is evenly installed with a plurality of crushing hammers 6, the crushing hammers 6 are rotatably connected to the crushing disk 5 and the rotation axes of the two are parallel to the rotation axis of the crushing disk 5.
[0024] Specifically, the crushing barrel 1 includes a cylindrical side wall, a top cover 101 and a bottom cover, and the top cover 101 and the bottom cover are detachably fixed to the side wall. A feed port 102 is provided at the center of the top cover 101 and penetrates the top cover 101 in the vertical direction, and a discharge port is provided at the edge of the bottom cover and penetrates the bottom cover in the vertical direction.
[0025] More specifically, because the crushing disc 5 is arranged at the bottom of the crushing barrel 1, the material generates a large cutting force between the bottom of the crushing barrel 1 and the crushing disc 5 and the crushing hammer 6, and thus the bottom of the Shudie crushing disc 5 needs to withstand a larger extrusion force. In this embodiment, the crushing barrel 1 is vertically divided into an upper barrel body and a lower barrel body, and a reinforcing rib is arranged on the outer wall of the lower barrel body to achieve structural reinforcement. In some other embodiments, the wall thickness of the lower barrel body can also be made greater than that of the upper barrel body, and the two can be fixed by bolt connectors or welding.
[0026] Specifically, the breaker hammer 6 here is roughly a square structure, and the breaker hammer 6 has an upper surface and a lower surface that are parallel to each other.
[0027] In this embodiment, with the rotation center of the crushing disk 5 as the axis, there is a gap 7 between the rotation trajectory of the crushing disk 5 farthest from its own rotation center and the inner wall surface of the crushing barrel 1. The existence of the gap 7 prevents the crushing disk 5 from directly colliding with the inner wall surface of the crushing barrel 1, and the existence of the gap 7 can reduce the probability of material blockage between the outer edge of the crushing disk 5 and the inner wall surface of the crushing barrel 1.
[0028] When in use, the rotation of the crushing disk 5 around its own axis will cause the crushing hammer 6 to be subjected to centrifugal force, and the centrifugal force causes the crushing hammer 6 to fill the above-mentioned gap 7, so that the crushing hammer 6 can crush the materials scattered in the gap 7, and lift the incompletely crushed materials upward until they come into contact with the crushing knives on the crushing disk 5 again; and the crushing hammer 6 can revolve around the center of the crushing disk 5 to push the crushed materials to the discharge port at the bottom end of the crushing barrel 1.
[0029] In this embodiment, the inner wall surface of the crushing barrel 1 has a plurality of protrusions 103 arranged around the crushing disk 5 , and the protrusions 103 are evenly distributed along the circumference of the crushing disk 5 .
[0030] Specifically, the protrusion 103 here is a rectangular parallelepiped structure, and the material of the protrusion 103 is the same as that of the crushing barrel 1. Multiple protrusions 103 are evenly distributed along the circumference of the crushing disk 5. This arrangement can form an uneven structure at the bottom end of the inner wall of the crushing barrel 1, thereby facilitating the use of the corner structure of the protrusion 103 in conjunction with the crushing hammer 6 to increase the crushing effect of the material.
[0031] In this embodiment, the vertical height of the protrusion 103 is not lower than that of the breaker 6. Preferably, the upper end of the protrusion 103 is flush with the upper end of the breaker 6.
[0032] In this embodiment, the side wall of the crushing barrel 1 has an installation groove 104 corresponding to the protrusion 103, part of the structure of the protrusion 103 is inserted into the installation groove 104, and the other part of the structure of the protrusion 103 protrudes from the inner wall surface of the crushing barrel 1 to extend into the inner cavity of the crushing barrel 1; the size of the protrusion 103 protruding from the inner cavity of the crushing barrel 1 can be adjusted and fixed.
[0033] In this embodiment, there is a transverse spring 105 in the mounting groove 104, and the spring 105 extends axially toward the crushing barrel 1. One end of the spring 105 is fixed to the bottom wall of the mounting groove 104, and the other end is fixed to the protrusion 103. In some other embodiments, the spring 105 can also be replaced by an elastic rubber block, one end of the rubber block is fixed to the side of the mounting groove 104 away from the inner wall of the crushing barrel 1, and the other end of the rubber block is bonded and fixed to the protrusion 103; optionally, the rubber block can also be fixed to the inner wall of the crushing barrel 1 through a bolt connector. In this embodiment, when the material is blocked between the protrusion and the crushing hammer, the protrusion is subjected to the angle extrusion force and the spring is compressed, and the protrusion shrinks into the mounting groove, thereby increasing the distance between the protrusion and the crushing hammer, so that the material is out of the blocked state. When the material at the protrusion is out of the blocked state, the elastic force of the spring causes the protrusion to extend outward and reset.
[0034] In this embodiment, the breaker 6 has an outer arc surface, and the center of the outer arc surface coincides with the central axis of the crushing barrel 1. This arrangement makes the distance between the outer arc surface of the breaker 6 and the inner wall surface of the crushing barrel 1 substantially the same, which is convenient for reducing the distance between the breaker 6 and the crushing barrel 1.
[0035] In this embodiment, a plurality of extensions are evenly distributed on the circumferential edge of the crushing disk 5, and a crushing hammer 6 is rotatably installed at one end of the extension away from the center of the crushing disk 5. The upper surface of the crushing disk 5 has a plurality of rows of crushing knives, and each row of crushing knives is arranged in sequence from the extension toward the center of the crushing disk 5.
[0036] Specifically, the crushing disk 5 includes a main body 501 structure, and the main body 501 extends outward along its outer diameter direction to form three extension parts. Figure 3 The main body 501 and the extension part are integrally formed, and there is no obvious dividing line between the two. In some other embodiments, the number of the extension parts can be four or five or other numbers, which can be set by those skilled in the art.
[0037] In this embodiment, the crushing blades include a first crushing blade 504 extending obliquely upward from the upper surface of the crushing disk 5 and a second crushing blade 503 extending vertically upward. Specifically, in the case of three extensions, the crushing blades include three groups, and each group of crushing blades is sequentially arranged from the main body 501 to the outside along the extension direction of the extension.
[0038] In this embodiment, a screw conveyor 2 is provided below the discharge port, and an inlet of the screw conveyor 2 abuts against the discharge port of the crushing barrel 1 .
[0039] In this embodiment, a driving shaft is installed at the lower part of the crushing disk 5. The driving shaft vertically penetrates the bottom of the crushing barrel 1. The driving shaft is connected to the power assembly through a transmission assembly.
[0040] Specifically, the power assembly here can adopt a driving motor, and the transmission structure can adopt a belt drive. Specifically, the output shaft of the driving motor is arranged downward and fixed coaxially with the first pulley, the driving shaft of the crushing disk 5 is fixed coaxially with the second pulley, and the first pulley and the second pulley are connected by a belt.
[0041] In some other embodiments, the power assembly can be replaced by a hydraulic motor, and the transmission assembly can be replaced by a gear set.
