[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shredder blade chamber that is easy to disassemble and assemble includes:

[0007] A blade cavity component assembly, comprising a lower blade cavity and an upper blade cavity, wherein the lower blade cavity and the upper blade cavity are rotatably connected by a pivot point;

[0008] A drive component assembly is provided to control the rotation angle of the upper cutting chamber. The drive component assembly includes a hydraulic rod, an upper end piece, and a lower end piece. The upper end piece is fixedly connected to the lower cutting chamber, and the lower end piece is fixedly connected to the upper cutting chamber. The two ends of the hydraulic rod are rotatably connected to the upper end piece and the lower end piece, respectively. There are two sets of drive component assemblies, and the two sets of drive component assemblies are symmetrically distributed on the back of the lower cutting chamber.

[0009] A locking component assembly for locking when the lower and upper cutting chambers are closed;

[0010] The cavity assembly includes a cavity door, the bottom of which is rotatably connected to a lower cutting chamber. A side rod is provided on the side of the cavity door, which is connected between the lower cutting chamber and the cavity door to drive the cavity door to rotate and open. A locking member is secured to one side of the cavity door through a groove, and the locking member is rotatably connected to the lower cutting chamber. An arc support, a locking assembly, and a screen plate are provided inside the lower cutting chamber.

[0011] Preferably, the lower cutting cavity is provided with an opening and closing limit corresponding to the upper cutting cavity. The opening and closing limit is a limiting protrusion fixed on the lower cutting cavity. The upper cutting cavity can be rotated and opened by 65° on the lower cutting cavity. When the upper cutting cavity rotates to 65°, the edge of the upper cutting cavity abuts against the limiting protrusion to limit the further rotation of the upper cutting cavity.

[0012] Preferably, the outer surface of the upper blade cavity is provided with reinforcing ribs, which are evenly distributed along the length of the upper blade cavity to improve the structural strength of the upper blade cavity, and a feed inlet is provided at the top of the upper blade cavity.

[0013] Preferably, the hydraulic rod is connected to a hydraulic pump via a hydraulic oil pipe, and the extension and retraction stroke of the hydraulic rod is adjusted by controlling the hydraulic pump.

[0014] Preferably, the locking component group includes a locking seat, a threaded rod is provided inside the locking seat, a nut and a washer are fitted on the threaded rod, and the locking component group is provided in five groups, and the five groups of locking component groups are evenly distributed on the lower blade cavity.

[0015] Preferably, the locking seat and the lower blade cavity are fixedly connected, one end of the threaded rod is rotatably connected to the locking seat, the threaded rod and the nut are connected by threads, and one side of the washer contacts the nut.

[0016] Preferably, the upper blade cavity is provided with grooves corresponding to the five sets of locking components, and the washer is used to contact the upper blade cavity.

[0017] Preferably, the lower blade chamber has an opening corresponding to the cavity door, the locking assembly has a cylinder and a threaded rod, one end of the threaded rod is connected to an operating handwheel, the other end of the threaded rod is provided with a locking block, the threaded rod contacts the end with the arc support through the locking block, the end of the arc support away from the locking assembly is rotatably connected to the lower blade chamber, and the arc support is supported at the bottom of the screen plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The existing technology of directly connecting the upper and lower cutting chambers with bolts is improved to an openable connection achieved through a rotation fulcrum. With the help of a drive system composed of hydraulic rods and hydraulic pump, the opening and closing angle of the upper cutting chamber can be precisely controlled (maximum 65°). Compared with the cumbersome operation of traditional bolt disassembly and assembly, hydraulic control realizes the labor-saving and rapid opening and closing of the upper and lower cutting chambers, which greatly improves the opening efficiency of the cutting chamber and solves the problem of limited maintenance space caused by fixed connection in the existing technology.

[0020] 2. The locking component group, consisting of a locking seat, threaded rod, nut and washer, achieves reliable limiting and locking after the upper and lower blade cavities are closed. The five evenly distributed locking structures, in conjunction with the corresponding slots of the upper blade cavity, not only ensure the locking stability but also simplify the operation process—locking and unlocking can be completed simply by rotating the nut. Compared with the complex locking methods in the existing technology, this improves the ease of operation, while mechanical limiting ensures the structural safety of the closed state.

[0021] 3. The screen plate can be replaced and maintained without disassembling the moving blades inside the blade chamber, which greatly simplifies the maintenance process and eliminates the complicated steps of disassembling the moving blades. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] One embodiment of this utility model is provided:

[0031] A shredder blade chamber that is easy to disassemble and assemble includes:

[0032] refer to Figures 1-3 The blade cavity component group 1 includes a lower blade cavity 11 and an upper blade cavity 12, which are rotatably connected by a pivot point.

[0033] refer to Figures 2-3 The drive component group 2 is used to control the rotation angle of the upper cutting chamber 12. The drive component group 2 includes a hydraulic rod 21, an upper end piece 22 and a lower end piece 23. The upper end piece 22 is fixedly connected to the lower cutting chamber 11, and the lower end piece 23 is fixedly connected to the upper cutting chamber 12. The two ends of the hydraulic rod 21 are rotatably connected to the upper end piece 22 and the lower end piece 23, respectively. The drive component group 2 is provided in two groups, and the two groups of drive component groups 2 are symmetrically distributed on the back of the lower cutting chamber 11.

[0034] refer to Figures 4-5 Locking component group 3, which is used to lock when the lower cutting chamber 11 and the upper cutting chamber 12 are closed;

[0035] refer to Figure 3 and Figure 6 The cavity assembly 4 includes a cavity door 41, the bottom of which is rotatably connected to the lower blade cavity 11. A side rod 42 is provided on the side of the cavity door 41, which is connected between the lower blade cavity 11 and the cavity door 41 to drive the cavity door 41 to rotate and open. A locking piece 43 is attached to one side of the cavity door 41 through a groove, and the locking piece 43 is rotatably connected to the lower blade cavity 11. The lower blade cavity 11 is provided with an arc support 44, a locking assembly 46, and a sieve plate 45.

[0036] The lower cutting cavity 11 is provided with an opening and closing limit corresponding to the upper cutting cavity 12. The opening and closing limit is a limiting protrusion fixed on the lower cutting cavity 11. The upper cutting cavity 12 can be rotated and opened by 65° on the lower cutting cavity 11. When the upper cutting cavity 12 rotates to 65°, the edge of the upper cutting cavity 12 abuts against the limiting protrusion to limit the further rotation of the upper cutting cavity 12.

[0037] It should be noted that the detachable upper and lower fixed tool holders on the lower tool chamber 11 are mainly used to install the upper and lower fixed tools. The upper and lower fixed tool holders are installed using a slot structure, which changes the original design. The original design welded the upper and lower fixed tool holders into the tool chamber, and the upper and lower fixed tools were fixed in the upper and lower fixed tool holders by bolts. After long-term use, the threads on the fixed tool holders are prone to wear, and after wear, the entire tool chamber can only be replaced. However, this design allows the fixed tool holders to be replaced directly.

[0038] The outer surface of the upper blade cavity 12 is provided with reinforcing ribs, which are evenly distributed along the length of the upper blade cavity 12 to improve the structural strength of the upper blade cavity 12. The top of the upper blade cavity 12 is provided with a feed port.

[0039] It should be noted that after the upper blade chamber 12 and the lower blade chamber 11 are closed, the upper blade chamber 12 is locked in position by the locking component group 3. In actual use, the blade rotates in the lower blade chamber 11. The rotating moving blade and the fixed blade on the lower blade chamber 11 cooperate to cut the material entering the upper blade chamber 12 through the feed port.

[0040] The hydraulic rod 21 is connected to a hydraulic pump via a hydraulic oil pipe, and the extension and retraction stroke of the hydraulic rod 21 is adjusted by controlling the hydraulic pump.

[0041] It should be noted that the opening and closing angle of the upper cutting chamber 12 on the lower cutting chamber 11 is controlled by the extension and retraction control of the hydraulic rod 21 driven by the hydraulic pump.

[0042] refer to Figure 4 and Figure 5 The locking component group 3 includes a locking seat 31, a threaded rod 32 is provided in the locking seat 31, and a nut 33 and a washer 34 are fitted on the threaded rod 32. The locking component group 3 is provided in five groups, and the five groups of locking component groups 3 are evenly distributed on the lower blade cavity 11.

[0043] The locking seat 31 and the lower blade cavity 11 are fixedly connected. One end of the threaded rod 32 is rotatably connected to the locking seat 31. The threaded rod 32 and the nut 33 are connected by threads. One side of the washer 34 contacts the nut 33.

[0044] The upper blade cavity 12 is provided with grooves corresponding to the five sets of locking components 3, and the washer 34 is used to contact the upper blade cavity 12.

[0045] It should be noted that when it is necessary to disconnect the lower cutting chamber 11 and the upper cutting chamber 12, the nut 33 is rotated to release the compression of the washer 34. Then, by rotating the locking seat 31, the locking of the upper cutting chamber 12 can be released. At this time, the upper cutting chamber 12 and the lower cutting chamber 11 are unlocked, and the upper cutting chamber 12 can be opened by the drive component group 2.

[0046] The lower blade chamber 11 has an opening corresponding to the cavity door 41. The locking assembly 46 contains a cylinder and a threaded rod. The cylinder and the threaded rod are threadedly connected. One end of the threaded rod is connected to an operating handwheel, and the other end of the threaded rod is provided with a locking block. The threaded rod contacts one end of the arc support 44 through the locking block. The end of the arc support 44 away from the locking assembly 46 is rotatably connected to the lower blade chamber 11. The arc support 44 is supported at the bottom of the screen plate 45.

[0047] It should be noted that the sieve plate 45 is supported by the rotatably mounted arc support 44 inside the lower blade chamber 11. The sieve plate 45 is stuck in the lower blade chamber 11 and is located below the rotating blade shaft. In actual use, the moving blade and the fixed blade in the blade chamber work together to crush the incoming material. The material that has been crushed to the appropriate particle size will pass through the sieve plate 45, while the larger particles will continue to remain on the sieve plate 45 and be crushed continuously. The appropriate particles will pass through the sieve plate 45 and the arc support 44 and fall into the bottom of the overall crusher. After prolonged use, the locking clip 43 can be rotated to disengage it from the groove of the cavity door 41. Then, the side rod 42 can be extended by activating it, pushing the cavity door 41 to rotate and open. The threaded rod in the locking assembly 46 can be rotated to move in the opposite direction to the arc support 44. One end of the threaded rod will be released from contact with the arc support 44, and the arc support 44 can be released from its limit and rotated in the lower blade cavity 11, thus releasing its supporting function on the screen plate 45. At this time, the screen plate 45 can be removed from the lower blade cavity 11 through the opening corresponding to the cavity door 41. The overall design allows the screen plate 45 inside the blade cavity to be replaced and maintained without disassembling the moving blade in the blade cavity.

[0048] Working principle:

[0049] Under normal operating conditions, the upper blade chamber 12 and the lower blade chamber 11 are closed, and the five sets of locking components 3 are in a locked state. The threaded rod 32 passes through the locking seat 31, and after the nut 33 is tightened, it squeezes the washer 34, making the washer 34 tightly contact the corresponding groove of the upper blade chamber 12, thereby fixing the upper blade chamber 12 onto the lower blade chamber 11. The material enters from the feed inlet, and the moving blade and the fixed blade in the lower blade chamber 11 cooperate to cut the material.

[0050] When maintenance is required, first rotate the nut 33 to release the pressure of the washer 34, rotate the locking seat 31 to unlock, and then drive the hydraulic rod 21 to extend and retract through the hydraulic pump, so that the upper blade chamber 12 rotates around the pivot point to open to 65° (limited by the restricted position protrusion), exposing the interior for easy maintenance; after completion, reverse the operation, close the upper blade chamber 12 and relock it through the locking component group 3.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
