Description

Technical Field

[0001] The utility model relates to the technical field of toothed roll crushers, and specifically relates to a toothed roll device for a crusher with uniform particle size. Background Art

[0002] For toothed roll crushing equipment, its working principle is that through the biting and squeezing generated by the relative rotation of two groups of toothed rolls arranged in parallel, the materials entering between the two rolls are forced to be broken. The gap between the two toothed rolls determines the final discharge particle size. At present, large teeth are adopted for this type of equipment, but due to the limitation of the tooth type size, the effects are not ideal, and at the same time, it causes many adverse effects such as large discharge particle size and increased use cost. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a toothed roll device for a crusher with uniform particle size, which can effectively solve the problems in the background art.

[0004] In order to achieve the above purpose, the utility model discloses a toothed roll device for a crusher with uniform particle size. The technical scheme adopted is as follows: it includes a roller, on which a crushing tooth and a rotating shaft are connected. A toothed plate is inserted on the roller, and the crushing tooth is detachably connected to the toothed plate. The crushing tooth also includes a large tooth and a small tooth, and the large tooth and the small tooth are arranged alternately. The large tooth can perform large-piece crushing on the materials, and the small tooth can perform small-piece tearing on the materials, thereby greatly reducing the discharge particle size and reducing the operation cost. A plug-in part is connected to the crushing tooth, an installation hole is opened on the toothed plate, and a connection mechanism is arranged on the toothed plate. The plug-in part is inserted into the installation hole and connected to the connection mechanism. The connection mechanism is a clamp-type connection mechanism and further includes oppositely arranged clamping strips. A clamping groove is opened on the plug-in part, and the clamping strips are clamped in the clamping groove, and the crushing tooth can be clamped and fixed through the clamping strips.

[0005] As a preferred technical scheme of the utility model, a dovetail groove is opened on the roller, and a dovetail block with a structure and size matching with it is arranged on the toothed plate. The dovetail block can be inserted into the dovetail groove, and the toothed plate can be removed when the crushing tooth needs to be adjusted.

[0006] As a preferred technical scheme of the utility model, convex blocks are formed on both sides of the dovetail groove; it further includes an end plate, which is an annular plate and is connected to the convex blocks through end bolts. The end plate can fix the toothed plate and prevent the toothed plate from sliding during operation.

[0007] As a preferred technical solution of the present utility model, the large tooth further includes tooth tips. The lower end surface of the tooth tips is connected to the insertion portion, which is an "I"-shaped connecting block. Clamping grooves are formed on both sides of the middle of the connecting block, and the pressure-receiving surface of the clamping groove is an inclined surface. The length and width dimensions of the upper and lower parts of the connecting block match the mounting holes. Squeezing the pressure-receiving surface can move the large tooth towards the roller direction; the difference between the small tooth and the large tooth lies in the different heights of the tooth tips.

[0008] As a preferred technical solution of the present utility model, the tooth plate further includes a housing and a bottom plate. The housing is a fan-shaped structure with an open bottom, and the open part is connected to the arc-shaped bottom plate through fastening bolts. The inner arc surface of the bottom plate is connected to the dovetail block; the mounting hole is communicated with the inside of the housing, and the connecting mechanism is located inside the housing. The connecting mechanism can be adjusted by opening the bottom plate.

[0009] As a preferred technical solution of the present utility model, a slideway is installed on the inner top surface of the housing. A T-shaped chute is formed on the slideway, and a clamping strip is slidably connected in the T-shaped chute. A slider is arranged on the top surface of the strip rod of the clamping strip, and the slider is a T-shaped slider and is slidably connected in the T-shaped chute; Two clamping strips are arranged in parallel, and opposite extrusion surfaces are arranged on the opposite surfaces of the two clamping strips. The extrusion surface is an inclined surface and is slidably connected to the pressure-receiving surface; A fixing mechanism is arranged on the clamping strip. When the two clamping strips move towards each other, the crushing teeth can be clamped tightly. Not only can the clamping force provide a positioning effect, but the frictional force formed by pressing the tooth tips of the crushing teeth downward can also improve the stability of the crushing teeth. The fixing mechanism can fix the position of the clamping strip.

[0010] As a preferred technical solution of the present utility model, the fixing mechanism further includes a fixing plate, which is connected to the clamping strip, and the fixing plate and the slideway are connected by bolts, and the bolt connection has better stability.

[0011] As a preferred technical solution of the present utility model, a spring is arranged between the two clamping strips. The spring can open the clamping strips after removing the bolts between the fixing plate and the slideway, which is convenient for disassembling and replacing the crushing teeth.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging large teeth and small teeth with staggered high and low teeth on the tooth plate, the present utility model improves the qualified rate of the discharge particle size on the premise of ensuring the biting ability of the toothed roller, reduces the pressure of the downstream crushing, improves the discharge qualification rate, and can control the biting gap by adjusting the distance between the two rollers to ensure that the particle size of the crushed material meets the standard. Compared with the previous unified large teeth, the qualified rate of the discharge particle size of this structure has increased by 30%-40%, greatly improving the utilization rate of the material and reducing the operation cost of customers.

[0013] Furthermore, by setting the crushing teeth as a detachable connection structure, it is possible to install crushing teeth of the expected height as needed, adjust the tooth size and arrangement according to needs, and have better adaptability. The connection mechanism used is a clamping connection mechanism, which can position a row of crushing teeth synchronously and has higher efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. Embodiment 1

[0030] As Figures 1 to 14 shown, the present invention discloses a toothed roll device for a crusher with uniform particle size. The technical solution adopted is to include a roller 1. As Figure 4 shown, rotating shafts 4 are coaxially arranged on the two end faces of the roller 1, and dovetail grooves 102 are opened on the arc surface. There are multiple dovetail grooves 102, which are arranged in a circular array. A dovetail-shaped bump 101 is formed between two adjacent dovetail grooves 102. As Figure 1 , Figure 2 shown, a toothed plate 2 is inserted into the dovetail groove 102.

[0031] As Figure 5 , Figure 6 shown, the toothed plate 2 further includes a housing 201 and a bottom plate 202. The housing 201 is a fan-shaped structure and is open at the bottom. The main body of the bottom plate 202 is an arc-shaped plate, and a dovetail block 203 with a structure consistent with that of the dovetail groove 102 and a matching size is installed on its inner arc surface. The arc-shaped plate is connected to the opening of the housing 201 by bolts. A counterbore is opened on the inner arc surface of the arc-shaped plate to accommodate the bolts and prevent the ends of the bolts from protruding from the inner arc surface. As Figure 11 , 12 shown, a square mounting hole 2011 is opened on the top arc surface of the housing 201. As Figures 5 to 10 shown, a large gear 5 and a small gear 6 are installed in the mounting hole 2011. Define Figure 5Among them, the rows are arranged in the arc direction, and the columns are arranged in the straight line direction. The same broken teeth are set in each row, and the broken teeth of two adjacent columns are staggered with large teeth 5 and small teeth 6.

[0032] As Figure 13 shown, the large tooth 5 further includes tooth teeth 501 and a connecting block 502. The connecting block 502 is in an "I" - shaped structure, including three parts: upper, middle, and lower. The upper and lower parts are both square - block structures. There are clamping grooves on both sides of the middle part, and the bottom surface of the clamping groove is the pressure - receiving surface 503, and the pressure - receiving surface 503 is an inclined surface. The sizes of the square blocks of the upper and lower parts are the same as the size of the mounting hole 2011. In order to improve the stability of the broken teeth, a gasket is installed between the tooth teeth 501 and the housing 201.

[0033] The structural composition of the small tooth 6 is the same as that of the large tooth 5. The difference between the two is that the tooth teeth 501 of the large tooth 5 are 5 mm higher than the tooth part of the small tooth 6, so that the large tooth 5 and the small tooth 6 can be meshed by adjusting the roller spacing.

[0034] In order to fix the broken teeth, a slideway 7 is provided on the inner top surface of the housing 201. As Figures 7 to 10 shown, a T - shaped chute is opened on the bottom surface of the slideway 7, and a clamping strip 8 is slidably connected in the T - shaped chute. As Figure 14 shown, a slider 803 is connected to the top surface of the bar 801 of the clamping strip 8. The slider 803 is a T - shaped slider and is slidably connected in the T - shaped chute. There are two clamping strips 8 in each group, and an extrusion surface 802 is provided on their opposite surfaces. The extrusion surface 802 is an inclined surface and is opposite to and slidably connected to the pressure - receiving surface 503 of the broken teeth. In order to make it easy for the clamping strip 8 not to loosen after clamping the broken teeth, a first fixing plate 805 and a second fixing plate 806 are provided on the same side of the two sliders 803. The first fixing plate 805 is higher than the second fixing plate 806, and first bolt holes are opened on both of them. As Figure 10 shown, a third threaded hole is opened in the T - shaped chute of the slideway 7, and a bottom block 11 is connected to the third threaded hole through a connecting bolt 12. A second threaded hole 1101 is opened on the bottom block 11. The second threaded hole 1101 has the same size and corresponding position as the first bolt hole. By using a fixing bolt 10 to pass through the first bolt hole and engage into the second threaded hole 1101, the position of the clamping strip 8 can be fixed. In order to enable the clamping strip 8 to release the extrusion on the pressure - receiving surface 503 after loosening the fixing bolt 10, sleeves 804 are provided on the opposite surfaces of the clamping strip 8, and a spring 9 is installed between the two opposite sleeves 804.

[0035] As Figure 5 、 Figure 6 、 Figure 12 shown, a fourth threaded hole 2012 is opened at the opening of the housing 201, and a second bolt hole is opened on the bottom plate 202. By using a fastening bolt to pass through the second bolt hole and engage into the fourth threaded hole 2012, the bottom plate 202 can be fixedly connected to the housing 201.

[0036] Working principle of the present utility model:

[0037] Remove the fastening bolt, open the bottom plate 202, put the gasket on the connecting block 502 of the large gear 5, align the bottom surface 504 of the large gear 5 with the mounting hole 2011 and install it. Install the small gear 6 in the same way. Pinch the two clamping bars 8 so that the pressing surface 802 on the bar 801 presses the pressed surface 503, and the tooth 501 presses the gasket to seal the joint. When the first bolt hole is opposite to the second threaded hole 1101, pass the fixing bolt through the first bolt hole and engage it with the second threaded hole 1101 to complete the fixation of the clamping bar 8.

[0038] Connect the bottom plate 202 to the housing 201 using the fastening bolt, insert the dovetail block 203 into the dovetail groove 102, and connect the end plate 3 to the first threaded hole 103 of the convex block 101 using the end bolt 301 to prevent the tooth plate 2 from sliding during operation.
