Abstract
The utility model discloses a hammer head protection structure of a double-shaft sand making machine, wherein all hammer heads of each hammer head group are fixedly connected with a core on a machine core shaft through a connecting shaft; two protection plates are arranged above the two machine core shafts, the two protection plates are respectively fixed on the front inner side wall and the rear inner side wall of the lower box body, the left end of each protection plate is positioned on the left side of one machine core shaft on the left side, and the right end of each protection plate is positioned on the right side of one machine core shaft on the right side; the protection plate bottom has a protection boss, and the protection boss of two protection plates sets up relatively, and the protection boss shelters from the gap between the core and the lower box of both sides. The scheme adjusts the arrangement mode of the hammer head, thereby being convenient for replacing the hammer head and not being capable of replacing the machine core shaft, and further saving the cost; the protection boss of protection shield shelters from the gap between the core and the lower box of sheltering from both sides completely, just so can prevent that the grit from here falling into the gap between the core and the lower box of both sides, avoids the grit card to die the core axle.
Description
Technical Field
The utility model belongs to biax system sand machine relates to a tup protection architecture of biax system sand machine.
Background
The double-shaft sand making machine is provided with two machine core shafts arranged side by side, and a machine core is integrally arranged on the machine core shafts. Be equipped with a hammer head group along the axial of core axle, every hammer head group comprises a plurality of tups along circumference equipartition, and the tup sets up with core an organic whole, and core axle rotates and supports on the box. When the hammer crusher works, the machine core shaft rotates and crushes gravels through the hammer head.
The existing defects are as follows:
1. in the process that the gravels fall down from top to bottom, the gravels easily fall between the machine cores on the two sides and the corresponding side walls, so that the machine cores are blocked, and the blocked gravels can only be hooked out by a method after the machine is stopped;
2. because the hammer and the core shaft are of an integral structure, when the clamped sand stone cannot be hooked out, only the core shaft can be detached, and the core shaft of the integral structure is very difficult to replace. In addition, the hammer head is abraded when working, the abrasion of the core shaft is small, and the cost is high when the whole hammer head is replaced.
SUMMERY OF THE UTILITY MODEL

The technical scheme of the utility model as follows: the utility model provides a tup protection architecture of biax system sand machine, includes box (1) down, is equipped with two core axles (2) side by side about on box (1) down, and the preceding of core axle (2), rear end rotate respectively to support on the lateral wall that box (1) corresponds down, are equipped with a hammer head group along the axial of core axle (2), and every hammer head group comprises a plurality of tups (3) along circumference equipartition, its characterized in that: all hammers (3) of each hammer group are fixedly connected with a machine core (2a) on a machine core shaft (2) through a connecting shaft (4);
two protection plates (5) are arranged above the two machine core shafts (2), the two protection plates are respectively fixed on the front inner side wall and the rear inner side wall of the lower box body (1), the left end of each protection plate (5) is positioned on the left side of the machine core shaft (2) on the left side, and the right end of each protection plate (5) is positioned on the right side of the machine core shaft (2) on the right side; the bottom of the protection plate (5) is provided with a protection boss (5a), the protection bosses (5a) of the two protection plates (5) are arranged oppositely, and the protection bosses (5a) shield the gap between the machine core (2a) on two sides and the lower box body (1).
Preferably, the top surface of the protection boss (5a) is an inclined surface, the high point of the inclined surface faces to the corresponding side wall of the lower box body (1), and the low point of the inclined surface faces to the corresponding side movement (2 a).
The protective plate (5) is a steel plate, the thickness of the protective plate is 10-20mm, and the protective plate is welded and fixed with the lower box body (1).
Has the advantages that:
1. the scheme adjusts the arrangement mode of the hammer head, thereby being convenient for replacing the hammer head and not being capable of replacing the machine core shaft, and further saving the cost;
2. the protection boss of protection shield shelters from the gap between the core and the lower box of sheltering from both sides completely, just so can prevent that the grit from here falling into the core and the lower box gap between both sides, avoids the grit card to die the core axle, guarantees the normal work of system sand machine.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 and 2, a hammer head protection structure of a double-shaft sand making machine comprises a lower box body 1, wherein two machine core shafts 2 are arranged on the lower box body 1 in parallel from left to right, the front ends and the rear ends of the machine core shafts 2 are respectively rotatably supported on the corresponding side walls of the lower box body 1, a hammer head group is arranged along the axial direction of the machine core shafts 2, and each hammer head group is composed of a plurality of hammer heads 3 uniformly distributed along the circumferential direction. All hammers 3 of each hammer group are fixedly connected with a core 2a on the core shaft 2 through a connecting shaft 4, and the connecting shaft 4 is tightly matched with the hammers 3 and the core 2 a. When the hammer head 3 is replaced, the connecting shaft 4 is only needed to be drawn out, and the hammer head 3 can fall off, so that the hammer head 3 is convenient to replace, the mandrel 2 does not need to be replaced, trouble is saved, and cost is reduced.
