Description
Technical Field
[0001] The utility model relates to the technical field of toothed rollers, and particularly relates to a detachable toothed plate of a toothed roller. Background Art
[0002] At present, domestic and foreign toothed rollers generally include a cylinder body, a main shaft and a toothed plate. The toothed plate is equally divided into multiple pieces. Through the connecting holes cast on the toothed plate and the threaded holes machined on the cylinder body, multiple toothed plates are fixed on the cylinder body along the circumferential direction of the cylinder body by bolts. The toothed plate in the prior art includes a base plate and crushing teeth, and the crushing teeth are integrally and fixedly formed with the base plate. However, usually the wear of the toothed plate is due to the serious wear of the crushing teeth outside the toothed plate, while the base plate of the toothed plate is basically not worn. But since the crushing teeth and the base plate are of an integral fixed structure, when the wear of the crushing teeth does not meet the crushing requirements, the entire toothed plate needs to be replaced, that is, the unworn base plate will be replaced together with the crushing teeth, resulting in huge waste, increased costs, and inconvenient operation during installation and disassembly, and low replacement efficiency. Summary of the Utility Model
[0003] The utility model provides a detachable toothed plate of a toothed roller, aiming to only replace the worn part of the crushing teeth when the crushing teeth are worn, without replacing the base plate of the toothed plate, thereby effectively saving the cost of vulnerable parts.
[0004] The utility model is realized by the following technical solutions: A detachable toothed plate of a toothed roller includes a base plate and at least one toothed block. A crushing tooth is connected to the toothed block. The toothed block is detachably connected to the base plate. Tooth grooves are formed on the base plate. The toothed block is slidably matched with the tooth grooves, and the toothed block can slide out of the tooth grooves.
[0005] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0006] In this solution, the toothed block is detachably connected to the base plate. In this way, when the crushing teeth on one of the toothed blocks are worn, only the toothed block with the worn crushing teeth needs to be slid out of the base plate, and then a new toothed block is replaced onto the base plate, without replacing the base plate and the toothed block together, thereby effectively saving the cost of vulnerable parts, and the replacement is more convenient and the operation efficiency is higher.
[0007] Further, a bottom groove communicating with the tooth grooves is formed at the bottom of the tooth grooves. The toothed block includes a connecting block and an inserting block. The connecting block is connected to the inserting block. The cross-sectional shapes of the connecting block and the inserting block respectively match the cross-sectional shapes of the tooth grooves and the bottom groove. The connecting block and the inserting block are respectively slidably matched with the tooth grooves and the bottom groove. The crushing tooth is connected to the connecting block.
[0008] Beneficial effects: In this solution, a bottom groove is provided at the bottom of the tooth groove, and the tooth block includes a connecting block and an inserting block. In this way, the connecting block and the inserting block are respectively in sliding fit with the tooth groove and the bottom groove, which can improve the stability of the sliding fit between the tooth block and the tooth groove. Moreover, the cooperation between the bottom groove and the inserting block can further enhance the limiting effect on the tooth block, making the detachable connection relationship between the tooth block and the substrate more stable, and ensuring the stability of the position of the tooth block during later use, so as to smoothly crush the material.
[0009] Furthermore, the bottom groove is a rectangular groove, the width of the rectangular groove is greater than the width of the tooth groove, and the inserting block is a rectangular inserting block.
[0010] Beneficial effects: In this solution, the bottom groove is a rectangular groove, the shape of the inserting block matches the shape of the bottom groove, and the width of the rectangular groove is greater than the width of the tooth groove. In this way, the tooth groove and the bottom groove form a T-shaped groove structure, and the inserting block and the connecting block form a T-shaped block. When the inserting block and the connecting block are respectively in fit with the bottom groove and the tooth groove, a stable sliding fit relationship can be formed, with better directivity and more accurate installation position.
[0011] Furthermore, the bottom groove is a dovetail groove, and the inserting block is a dovetail inserting block.
[0012] Beneficial effects: In this solution, the bottom groove is a dovetail groove and the inserting block is a dovetail inserting block. In this way, the cooperation precision between the dovetail inserting block and the dovetail groove is higher, and the directivity for the tooth block is more accurate, thus making the connection between the tooth block and the substrate more stable.
[0013] Furthermore, two symmetric first inclined surfaces are provided on both sides of the substrate. When two adjacent substrates are spliced, the first inclined surfaces of the two adjacent substrates abut against each other.
[0014] Beneficial effects: Since multiple tooth plates need to be connected and fitted along the circumferential direction of the cylinder later, in this solution, due to the symmetric first inclined surfaces provided on both sides of the substrate, when multiple tooth plates are circumferentially fitted with each other, the first inclined surfaces on the substrates of two adjacent tooth plates will cooperate and abut against each other, making the cooperation between the substrates in adjacent tooth plates closer, reducing the gaps generated during assembly, and thus improving the quality of the entire tooth roller.
[0015] Furthermore, both sides of the tooth block are flush with the first inclined surfaces on both sides of the substrate respectively.
[0016] Beneficial effects: With such a setting, the tooth block and the substrate can form an integral body, making the tooth block and the substrate more matching, facilitating later assembly, and meeting the assembly quality requirements.
[0017] Furthermore, the first inclined surface is located at the upper part of the substrate, and second inclined surfaces are also provided on both sides of the substrate and at its lower part. The second inclined surfaces are connected to the first inclined surfaces, and the slope of the second inclined surface is smaller than the slope of the first inclined surface.
[0018] Beneficial effects: Since the contact surfaces involved in the machining manufacturing process require metal processing, the second inclined surface in this solution reduces the contact surface with the cylinder body, thereby reducing the metal processing technology, lowering the production and manufacturing costs, reducing the production process flow, and thus improving the processing efficiency. In addition, the setting of the second inclined surface can reduce the overall weight of the substrate, making the weight of the entire formed toothed roll lighter in the later stage.
[0019] Furthermore, a limiting groove is opened at the bottom of the substrate, and the limiting groove is of a through groove structure.
[0020] Beneficial effects: The limiting groove at the bottom of the substrate in this solution facilitates the installation and positioning during the later assembly with the cylinder body, so that the assembly efficiency and assembly accuracy are higher.
[0021] Furthermore, the bottom of the substrate is a plane.
[0022] Beneficial effects: With such a setting, the shape of the cylinder body can be set as a polygonal structure. When multiple toothed plates are connected and matched with the cylinder body, since the bottom of the substrate of the toothed plate is a plane, it can match the shape of the cylinder body, and the end face shape formed by the bottom of the cylinder body and multiple toothed plates is a polygonal structure, which can make the connection and cooperation between the toothed plate and the cylinder body more stable and firm, thereby improving the quality of the entire toothed roll.
[0023] Furthermore, the top side surface of the substrate is an arc surface, and the top side surface of the tooth block is an arc surface that matches the top side surface of the substrate.
[0024] Beneficial effects: With such a setting, the top side surface of the entire toothed plate can be an arc surface. In the later stage, when multiple toothed plates are distributed in a circular pattern and connected and matched, a cylindrical rotor body is formed, and the effect of crushing materials is better.

[0036] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions of the present utility model are only used to explain the present utility model and are not used to limit the present utility model.
[0037] Embodiment 1
[0038] As Figures 1 - 2 shown, Embodiment 1 of the present embodiment provides a detachable tooth roller tooth plate, which includes a base plate 1 and at least one tooth block 2. The tooth block 2 is detachably connected to the base plate 1. In this embodiment, three tooth blocks 2 are provided on each base plate 1. A crushing tooth 3 is connected to the tooth block 2. There are three crushing teeth 3 on the tooth block 2, and the three crushing teeth 3 on the tooth block 2 are of different heights. As Figure 3 shown, in this embodiment, three tooth grooves 101 are opened on the base plate 1, and the three tooth blocks 2 are respectively in sliding fit with the three tooth grooves 101, and the tooth block 2 can slide out of the tooth groove 101.
[0039] In this embodiment, the bottom of the base plate 1 is a plane, the top side surface of the base plate 1 is an arc surface, and the top side surface of the tooth block 2 is an arc surface that matches the top side surface of the base plate 1.
[0040] Combined with Figure 4 shown, in this embodiment, a bottom groove 1011 communicating with the tooth groove 101 is opened at the bottom of the tooth groove 101. Combined withFigure 6 As shown, the tooth block 2 includes a connecting block 201 and an inserting block 202. The connecting block 201 is connected to the inserting block 202. In this embodiment, the connecting block 201 and the inserting block 202 are integrally formed. The cross-sectional shapes of the connecting block 201 and the inserting block 202 respectively match the cross-sectional shapes of the tooth groove 101 and the bottom groove 1011. The connecting block 201 and the inserting block 202 are respectively in sliding fit with the tooth groove 101 and the bottom groove 1011. In this embodiment, the shape of the connecting block 201 matches the shape of the tooth groove 101, that is, the top side surface of the connecting block 201 is also an arc surface. Three crushing teeth 3 are spaced and connected to the connecting block 201.
[0041] Combined with Figure 4 As shown, in this embodiment, the bottom groove 1011 is a rectangular groove, and the width of the rectangular groove is greater than the width of the tooth groove 101. Combined with Figure 6 As shown, the inserting block 202 is a rectangular inserting block 202, and the width of the rectangular inserting block 202 is greater than the width of the connecting block 201.
[0042] Combined with Figure 5 , both sides of the substrate 1 are provided with symmetric first inclined surfaces 104. As Figure 8 shown, when two adjacent substrates 1 are spliced, the first inclined surfaces 104 of the two adjacent substrates 1 can abut against each other. Combined with Figure 7 shown, after the tooth block 2 is installed in the tooth groove 101 of the substrate 1, both sides of the tooth block 2 are flush with the first inclined surfaces 104 on both sides of the substrate 1 respectively.
[0043] As Figure 5 shown, the first inclined surface 104 is located at the upper part of the substrate 1. Second inclined surfaces 105 are also provided on both sides of the substrate 1 and at its lower part. The second inclined surfaces 105 are connected to the first inclined surfaces 104. In this embodiment, the first inclined surfaces 104 and the second inclined surfaces 105 are connected by an arc transition, and the slope of the second inclined surface 105 is less than the slope of the first inclined surface 104.
[0044] Combined with Figure 2 shown, in this embodiment, a limiting groove 102 is opened at the bottom of the substrate 1, and the limiting groove 102 is a through groove structure.
[0045] The specific implementation process is as follows:
[0046] Combined with Figure 8 shown, a complete tooth roller is composed of a cylinder body 4, a main shaft and a plurality of detachable tooth plates. The main shaft is coaxially connected to the cylinder body 4. The main shaft is connected to an existing power mechanism, and the power mechanism drives the main shaft to rotate, thereby driving the entire tooth roller to rotate to crush materials. In this embodiment, six groups of tooth plates are taken as an example for illustration. The number of each group of tooth plates is at least one, that is, a complete tooth roller is composed of one or more tooth plates spliced together, and the number of each group of tooth plates in the axial direction of the cylinder body 4 is at least one.
[0047] Since the bottom of the base plate 1 of the tooth plate is flat, in order to match the shape of the tooth plate, the end face shape of the cylinder 4 is a polygonal structure. A limiting block 401 is integrally connected to each side of the cylinder 4. The base plates 1 of the six groups of tooth plates are sequentially connected to the six sides of the cylinder 4 in a circumferential distribution manner to form a complete rotor body structure. During assembly, the limiting groove 102 opened at the bottom of the base plate 1 of the tooth plate can be stuck on the limiting block 401 of the cylinder 4 to limit the base plate 1.
[0048] The first inclined surfaces 104 between adjacent base plates 1 abut against each other, and the ends of the tooth blocks 2 on adjacent base plates 1 abut against each other, which plays a role in limiting the tooth blocks 2. In this way, when the assembly of multiple groups of tooth plates is completed, the tooth blocks 2 between adjacent base plates 1 will not slide out of the tooth grooves 101 of the base plates 1.
[0049] As Figure 3 shown, a plurality of connection holes 103 are opened on the base plate 1, and threaded holes are machined on the cylinder 4. Between the base plate 1 and the cylinder 4, the base plate 1 and the cylinder 4 also need to be connected and fixed by inserting bolts into the connection holes 103 and the threaded holes.
[0050] When it is found that a certain crushing tooth 3 is worn and needs to be replaced, by removing the base plate 1 corresponding to the worn crushing tooth 3, and then sliding the whole tooth block 2 corresponding to the worn crushing tooth 3 out of the base plate 1, as Figure 1 shown in the state, and then replacing a new set of tooth blocks 2 can complete the disassembly and replacement. The operation is simple and convenient. In this way, there is no need to replace the base plate 1 together, effectively saving the cost of vulnerable parts.
[0051] The utility model adopts a detachable tooth roller tooth plate. During the use of the tooth roller, after the high and low crushing teeth on the tooth roller are worn, only the movable tooth blocks need to be replaced to replace the high and low crushing teeth, and the movable high and low crushing teeth do not need to be fixed by bolts, which is convenient for replacement. And the base body of the tooth plate does not need to be replaced, greatly saving the cost of vulnerable parts.
[0052] Embodiment 2
[0053] The difference between this embodiment and Embodiment 1 is that: the bottom groove 1011 in this embodiment is a dovetail groove, and the insertion block 202 is a dovetail insertion block 202. This embodiment provides another sliding fit structural shape of the bottom groove 1011 and the insertion block 202, and the matching precision of the dovetail groove and the dovetail insertion block is relatively high.
