Abstract

The utility model relates to a combined type dental plate, which is the improvement of an existing dental plate of a crusher. The utility model is mainly composed of a dental plate seat frame, a dental plate and a locking plate provided with teeth, wherein, inclined slop surfaces with identical slope degrees are arranged on the dental plate seat frame, the dental plate and the locking plate provided with teeth so as to enable the dental plate seat frame, the dental plate and the locking plate provided with teeth to match with one another; the dental plate comprises dental plates arranged on both ends and a dental plate arranged on the middle part. The utility model can greatly raise the utilization rate of dental plates and reduce the using cost of the dental plate, and the utility model is very easy to fabricate and use.

Description

The combined type dental lamina

The utility model belongs to a kind of disintegrating machine dental lamina, particularly a kind of combined dental lamina.

Disintegrating machine belongs to a kind of broad-spectrum mine and engineering machinery, it mainly is made up of engine and dental lamina, its dental lamina is divided into fixedly dental lamina and movable dental lamina two parts, is produced with respect to the reciprocating motion of fixing dental lamina by engine driving activity dental lamina things such as ore, stone are carried out fragmentation.The dental lamina of existing disintegrating machine is generally cast by casting manganese steel one because the foundry goods volume is big, thereby casting cost height, in case and the dental lamina wearing and tearing, have only more to renew dental lamina, so the dental lamina utilization rate is low, use cost is higher.

The purpose of this utility model is to design a kind of combined type dental lamina at existing dental lamina casting cost height, utilization rate is low, use cost is high defective, in the hope of reducing the dental lamina cost, improves its utilization rate, reduces its use cost.

Major technique measure of the present utility model is as follows:

A kind of combined type dental lamina comprises fixedly dental lamina and movable dental lamina, and they are formed by dental lamina seat frame, tooth plate and band tooth jam plate, wherein:

Dental lamina seat frame is made up of base plate and four sides wallboard, and its forward and backward two wallboards are vertical with base plate, and the angle of left and right two wallboards and base plate is an acute angle, has at least 3 positioning and locking screws in back before the base plate on center line;

Tooth plate comprises two ends tooth plate and middle tooth plate, and tooth plate is provided with crushing teeth, and vertical two ends of each tooth plate all are the slope, and the gradient angle on this slope equates with the wallboard inclination angle, left and right two sides of dental lamina seat frame;

Band tooth jam plate cross section is infundibulate, its top is the crushing teeth identical with the tooth plate shape, screw rod is established in the bottom, in the positioning and locking screw that this screw rod can insert on the base plate to be opened, is with the left and right surface slope of tooth jam plate to equate so that can make up mutually between them with the vertical two ends of tooth plate ramp slope.

Its installation method is as follows: set up tooth plate respectively on the left and right both sides of dental lamina seat frame earlier, between left and right two toothrow plates, put band tooth jam plate again, to be with the screw rod of tooth jam plate to insert in the positioning and locking screw of base plate, and screw in nut and fastening then on screw rod, dental lamina is promptly accused and is finished.Fixedly dental lamina is identical with the movable teeth plate structure for it, and its difference only is appearance and size and number of teeth difference, so not separated superfluous chatting.After certain a part of tooth (as two end teeth) wearing and tearing,, or only need change corresponding tooth plate and get final product as long as each tooth plate transposition can be used, thereby use cost is significantly reduced, because the cast in one piece volume is little, so qualified casting improves, the casting cost also can be minimized simultaneously.

Below in conjunction with accompanying drawing the utility model is further described:

This combined type dental lamina comprises fixedly two kinds of dental laminas and movable dental lamina, and these two kinds of dental lamina structures are identical, and its difference only is the difference of the appearance and size and the number of teeth, so merge together narration, they are formed by dental lamina seat frame 1, tooth plate 2 and band tooth jam plate 3, as shown in Figure 1, the casting of employing hot-die, wherein:

Dental lamina seat frame 1, see also Fig. 2,3, it is made up of base plate 11 and four sides wallboard 12,13, its forward and backward two wallboards 12 are vertical with base plate 11, left and right two wallboards 13 are an acute angle with the angle of base plate 11, the back has at least 3 positioning and locking screws 15 on center line before base plate 11, for improving the mechanical strength of base plate 11, also is provided with reinforcement 14 on plane under the base plate 11.

Tooth plate 2 sees also Fig. 4,5,6,7,8, and it comprises two ends tooth plate 21 and middle tooth plate 22, and tooth plate is provided with crushing teeth, and vertical two ends of each tooth plate all are the slope, and the gradient angle on this slope equates with the wallboard inclination angle, left and right two sides of dental lamina seat frame 1.

Band tooth jam plate 3, see also Fig. 9,10,11, its cross section is infundibulate, top is and the identical crushing teeth of tooth plate 2 shapes, screw rod 31 is established in the bottom, screw rod 31 can insert in the positioning and locking screw of being opened on the base plate 11 15, preferably adopt twin-screw and make the positioning and locking screwhole position and reinforcement 14 staggers, so that reinforcement is injury-free, the left side of band tooth jam plate 3, the right tilted surface gradient equates with tooth plate 2 vertical two ends ramp slopes so that can make up mutually between them, can fill up the thick iron sheet of 1.5mm to increase the effective contact-making surface between the two between dental lamina seat frame 1 and tooth plate 2.

Through practice test, prove that the utilization rate of this combined type dental lamina can reach 60-65%, far above the level of existing disintegrating machine dental lamina utilization rate 30%, thereby greatly reduce user's use cost.
