The utility model belongs to the technical field of pre-screening machines, and in particular relates to a grate of a pre-screening machine, comprising a grate body and a lower card slot arranged at the lower end of the body, which is characterized in that a The upper groove, the lower groove is set at the lower end of the grate bar body, and positioning pins are respectively inserted in the upper groove and the lower groove, and the positioning pins are connected with the fixed plate of the pre-screening machine. The embodiment of the present utility model is: make the grate bar with groove at both ends. Prepare the fixed pin matching the size of the groove and weld it on the bottom plate of the pre-screening machine. The prepared pre-screening grate is installed, the lower groove is installed on the fixing pin, the lower clamping groove is fixed, and finally the upper groove is fixed on the upper fixing pin, and the implementation is completed. The beneficial effect of the utility model is that the grate can be effectively fixed, the size of the screen hole can be ensured, the screening efficiency can be improved, and the ore breaking efficiency of the crusher can be improved at the same time, so as to realize the maximization of the production capacity of the system.
Description
Technical field
The utility model belongs to prescreening machine technology field, is specifically related to a kind of grate bar of prescreening machine.
Background technology
Prescreening belongs to the hold-down bars bar grizzl(e)y, the compass screen surface angle is 45 degree, compass screen surface is divided into, in, following three parts, every row has 20 rods, the installation form of every rod is, the lower end adopts hook mode to be installed on the sieve nest crossbeam, the upper end is floating to be placed on the sieve nest crossbeam, puts successively, breaks during this prescreening is applied to before the disintegrating machine, can effectively improve the broken ore deposit efficient of disintegrating machine, avoid pulverizing, and also can guarantee the disintegrating machine feed preparation unit size simultaneously, but in actual use, because the raw ore ore grain size is bigger, often the grate bar is beaten and scurried the position and float, cause screen size to exceed standard, cause the bigger ore of granularity to enter into screening system, form circulating load, increase system processing power.The ore that exceeds standard also can cause thin broken broken canopy bulk, and the broken ore deposit of influence efficient reduces system's production capacity.
Summary of the invention
The purpose of this utility model is to provide a kind of grate bar of prescreening machine, can significantly improve the prescreening effect, improves screening efficiency.
The purpose of this utility model is achieved through the following technical solutions.
The grate bar of prescreening machine of the present utility model, the body that comprises the grate bar, be located at the lower bayonet slot of this body lower end, it is characterized in that upper groove being set in the upper end of described grate bar body, lower end at described grate bar body is provided with low groove, insert alignment pin in this upper groove, the low groove respectively, this alignment pin is connected with the fixed head of prescreening machine.
Embodiment of the present utility model is: 1. casting: the grate bar of prescreening grate bar being made the double headed roller groove.2. be ready to the steady pin that matches with groove size, be welded on the base plate of prescreening machine.3. the prescreening grate bar that makes is installed, at first low groove is installed on the steady pin, simultaneously lower bayonet slot is fixed, at last upper groove is fixed on the steady pin of top, install in order then.
The beneficial effects of the utility model are: can effectively fix the grate bar, guarantee screen size, improve screening efficiency, also can improve the broken ore deposit efficient of disintegrating machine simultaneously, realize the maximization of system's production capacity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of the utility model Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
As shown in Figure 1, 2, the grate bar of prescreening machine of the present utility model, the body that comprises the grate bar, be located at the lower bayonet slot 3 of this body lower end, it is characterized in that upper groove 2 being set in the upper end of described grate bar body, lower end at described grate bar body is provided with low groove 1, inserts alignment pin respectively in this upper groove 2, the low groove 1, and this alignment pin is connected with the fixed head of prescreening machine.
Embodiment of the present utility model is: 1. casting: the grate bar of prescreening grate bar being made the double headed roller groove.2. be ready to the steady pin that matches with groove size, be welded on the base plate of prescreening frame.3. the prescreening grate bar that makes is installed, at first low groove 1 is installed on the steady pin, simultaneously lower bayonet slot 3 is fixed, at last upper groove 2 is fixed on the steady pin of top, install in order then, promptly finish enforcement.
The beneficial effects of the utility model are: can effectively fix the grate bar, guarantee screen size, improve screening efficiency, also can improve simultaneously the broken ore deposit efficient of disintegrating machine, the maximization of realization system production capacity improves system's production capacity, the optimized production process flow process, improve thin broken engine efficiency about 5%, realize the productivity effect maximization.
