Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a new hammer piece for a de-impurity pulping machine. Background Art

[0002] Pulping machine is a key equipment used in the field of food waste treatment and food waste resource utilization. Among its components, hammer plays an important role in crushing waste materials. Figure 4 As shown in the figure, the hammer design of the traditional kitchen waste and food waste pulping machine is generally made of a whole wear-resistant material. When it is worn to a certain extent, it needs to be replaced as a whole. The price of wear-resistant materials is much higher than that of ordinary materials, which leads to a high cost of using the hammer. Figure 5 As shown, after installation, this conventional hammer is arranged between the mounting plates and lacks a protective structure for the mounting plates. As a result, when the hammer is used for crushing, the mounting plates are also affected by wear when the hammer itself is worn. Therefore, both need to be replaced together during maintenance, which further increases costs and is not conducive to the long-term use of the equipment. Therefore, there is an urgent need for a new hammer that can protect the mounting plates during operation to reduce the wear of the mounting plates. Utility Model Content

[0003] The purpose of the utility model is to provide a new hammer for a pulping machine to solve the problem that the hammer of the existing pulping machine is unreasonable in structure, thereby causing the mounting plate to be synchronously worn.

[0004] The utility model provides the following technical solutions: A new hammer for a de-impurity pulping machine, comprising a hammer body, a hinge mechanism provided on the hammer body, and a protective mechanism, wherein the hammer body is provided with a hammer end and a connecting end arranged oppositely, the protective mechanism comprises a clearance notch provided at the connecting end, the hinge mechanism comprises a first fork hinge ear and a second fork hinge ear connected to the connecting end, the first fork hinge ear and the second fork hinge ear being arranged oppositely on both sides of the clearance notch, so that a protective interlayer is formed between the first fork hinge ear and the second fork hinge ear, and when the hammer body is hinged to the mounting plate, the first fork hinge ear and the second fork hinge ear are hinged on both sides of the mounting plate, so that the mounting plate is sandwiched in the protective interlayer.

[0005] In the novel hammer for a de-impurity pulping machine as described above, the surface of the hammer end is covered with a surfacing wear-resistant layer.

[0006] The novel hammer for the impurity removal pulping machine as described above has a hammer block detachably connected to the hammer end.

[0007] In the novel hammer for a waste removal pulping machine as described above, the clearance notch extends in a direction close to the hammer end to increase the radial width of the protective interlayer around the hinge axis at the connecting end.

[0008] As described above, a new hammer for a de-impurity pulping machine has coaxially arranged pin holes on the first fork hinge ear and the second fork hinge ear. When the hammer body is hinged to the mounting plate, the two ends of the pin provided on the mounting plate are respectively connected to the pin holes on the first fork hinge ear and the second fork hinge ear. At this time, the first fork hinge ear, the second fork hinge ear and the mounting plate are all arranged in parallel.

[0009] In the novel hammer for a de-impurity pulping machine as described above, the hammer body is perpendicular to the first fork hinge ear and the second fork hinge ear, and the hammer body coincides with the hinge axis of the first fork hinge ear and the second fork hinge ear.

[0010] In the novel hammer for a de-impurity pulping machine as described above, the hammer body is perpendicular to the first fork hinge ear and the second fork hinge ear, and the hammer body intersects with the hinge axis of the first fork hinge ear and the second fork hinge ear.

[0011] In the novel hammer for a de-impurity pulping machine as described above, the surfacing wear-resistant layer covers the edge surface of the hammer end on the side away from the connecting end.

[0012] In the novel hammer for a de-impurity pulping machine as described above, the surfacing wear-resistant layer completely covers the surface of the hammer end.

[0013] In the novel hammer for the impurity removal pulping machine as described above, the hammer block is made of alloy.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The utility model discloses a new hammer for a de-impurity pulping machine, which adopts the cooperation of an articulated mechanism and a protective mechanism on the main body of the hammer, without the need to use wear-resistant materials. The articulated mechanism is provided with a first fork lug and a second fork lug for articulating the mounting plate. A recess in the protective mechanism forms a protective interlayer between the first fork lug and the second fork lug. The mounting plate is sandwiched in the protective interlayer when in the articulated state, so that the only vulnerable part of the rotor device of the de-impurity pulping machine is the hammer main body. While greatly reducing the use cost of the hammer, it also protects other parts of the de-impurity pulping machine and avoids wear of other parts, thereby reducing the use and maintenance cost of the entire de-impurity pulping machine.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to the attached Figure 1 To the attached Figure 3The present embodiment provides a new hammer for a de-impurity pulping machine, comprising a hammer body 1, a hinge mechanism 2 provided on the hammer body 1, and a protective mechanism 3. The hammer body 1 is provided with a hammer end 11 and a connecting end 12 respectively arranged opposite to each other. The protective mechanism 3 includes a clearance notch 31 provided at the connecting end 12. The hinge mechanism 2 includes a first fork hinge ear 21 and a second fork hinge ear 22 connected to the connecting end 12. The first fork hinge ear 21 and the second fork hinge ear 22 are arranged on both sides of the clearance notch 31 opposite to each other, so that a protective interlayer 32 is formed between the first fork hinge ear 21 and the second fork hinge ear 22. When the hammer body 1 is hinged to the mounting plate, the first fork hinge ear 21 and the second fork hinge ear 22 are hinged on both sides of the mounting plate, so that the mounting plate is sandwiched in the protective interlayer 32. The novel hammer for the impurity removal pulping machine of the present embodiment adopts the cooperation of the hinge mechanism 2 and the protection mechanism 3 on the hammer body 1 without using wear-resistant materials. The hinge mechanism 2 is provided with a first fork lug 21 and a second fork lug 22 for hingedly connecting the mounting plate. The clearance notch 31 in the protection mechanism 3 forms a protective interlayer 32 between the first fork lug 21 and the second fork lug 22. The mounting plate is sandwiched in the protective interlayer 32 when in the hinged state, so that the hammer body 1 is the only vulnerable part of the rotor device of the impurity removal pulping machine. While greatly reducing the use cost of the hammer, it also protects other parts of the impurity removal pulping machine and avoids wear of other parts, thereby reducing the use and maintenance cost of the entire impurity removal pulping machine.

[0024] Preferably, if Figure 2 As shown, the surface of the hammer end 11 is covered with a hardfacing wear-resistant layer 111. Furthermore, based on actual cost adjustments, the hardfacing wear-resistant layer 111 can be applied to the edge surface of the hammer end 11 away from the connecting end 12; or the hardfacing wear-resistant layer 111 can completely cover the surface of the hammer end 11. The hardfacing wear-resistant layer 111 is a special alloy wear-resistant layer with high hardness and high wear resistance. This hardfacing wear-resistant layer 111 has a longer service life than ordinary wear-resistant materials. The cost of localized hardfacing is lower than that of hammers made entirely of wear-resistant materials, which can extend the service life of the hammer.

[0025] Preferably, if Figure 3 As shown, the hammer end 11 is detachably connected to a hammer block 112. Under the premise of not using a wear-resistant layer, the hammer block 112 can also be added. Furthermore, the hammer block 112 is made of alloy. When the wear part is maintained or replaced, only the hammer block 112 needs to be replaced, which reduces the maintenance cost.

[0026] The clearance notch 31 extends in a direction close to the hammer end 11 to increase the radial width of the protective interlayer 32 around the hinge axis on the connecting end 12 and reduce interference of the mounting plate on the hammer body 1 .

[0027] The first shift fork hinge ear 21 and the second shift fork hinge ear 22 are both provided with coaxially arranged pin holes 23. When the hammer body 1 is hinged to the mounting plate, the two ends of the pin provided on the mounting plate are respectively connected to the pin holes 23 on the first shift fork hinge ear 21 and the second shift fork hinge ear 22. At this time, the first shift fork hinge ear 21, the second shift fork hinge ear 22 and the mounting plate are all arranged in parallel, ensuring that in the hinged state, the first shift fork hinge ear 21 and the second shift fork hinge ear 22 are more tightly clamped on the mounting plate.

[0028] In the rotor assembly, part of the hammer body 1 is perpendicular to the first and second shift fork hinge ears 21, 22, and the hammer body 1 coincides with the hinge axis of the first and second shift fork hinge ears 21, 22; and part of the hammer body 1 is perpendicular to the first and second shift fork hinge ears 21, 22, and the hammer body 1 intersects the hinge axis of the first and second shift fork hinge ears 21, 22. Based on the rationality of the structure, these two types of hammer bodies 1 are used to be installed in different positions in the rotor assembly.

[0029] The working mode of the new hammer of this embodiment is as follows: when the hammer is working, it rotates at high speed with the main shaft. Under the action of centrifugal force, the hammer is distributed in a radial direction along the impurity removal pulping machine rotor. The hammer end 12 contacts the garbage, that is, the welded wear-resistant layer 111 or the hammer block 112 contacts the garbage. When the hammer is working, the first fork hinge ear 21 and the second fork hinge ear 22 on the hammer sandwich the hammer mounting plate in the middle to prevent the hammer mounting plate from directly contacting the garbage, thereby protecting the hammer mounting plate and delaying its wear.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
