DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a mortar screening device for bonding mortar for thermal insulation system, comprising: a screening box body 1, a feeding port 2, a pushing port 3, a driving gear 4, a first gear 5, a first connecting rod 6, a first chute 7, a pushing block 8, a second gear 9, a second connecting rod 10, a second chute 11, a limit frame 12, a screening frame 13, a limit slot 14, a screen 15, a stop bar 16, a connecting belt 17 and a motor 18;

[0029] When using the mortar screening device for bonding mortar for the thermal insulation system, if Figure 1 and Figure 5As shown, the mortar raw material bag is disassembled and then inverted in the feeding port 2, the raw materials in the bag will enter the pushing port 3 along the feeding port 2, and the motor 18 will be started. The motor 18 will drive the driving gear 4 to rotate. Since the driving gear 4 is meshed and connected with the first gear 5 and the second gear 9, the driving gear 4 will drive the first gear 5 and the second gear 9 to rotate together. When the first gear 5 rotates, the first connecting rod 6 on the first gear 5 will rotate together, and the first connecting rod 6 slides in the first chute 7. The first connecting rod 6 will make the first chute 7 reciprocate left and right. When the first chute 7 moves to the left, the first chute 7 will push the pushing block 8 to move left together, and the raw materials located at the inner side of the pushing port 3 will be pushed out of the pushing port 3 by the pushing block 8. Since the reciprocating distance of the first chute 7 is fixed, the weight of the raw materials pushed out by the pushing block 8 each time is also fixed, which can prevent too much material from being discharged at one time and clogging the screen 15 below.

[0030] like Figure 1 and Figure 4 As shown, a second connecting rod 10 is fixedly connected to the front side of the second gear 9, and the second connecting rod 10 slides in the second slide groove 11. The rotation of the second gear 9 will cause the second slide groove 11 to reciprocate left and right, and the second slide groove 11 will push the screening frame 13 connected thereto to reciprocate left and right on the limiting groove 14 inside the limiting frame 12. The limiting groove 14 is symmetrical about the vertical center axis of the limiting frame 12. A groove is provided on the inner side of the limiting groove 14 to prevent the screening frame 13 from deflecting on the limiting groove 14, thereby extending the service life, and the length of the screening frame 13 is sufficient When the screening frame 13 moves to the leftmost side, the raw materials pushed out from the pushing port 3 will also fall on the inner side of the screening frame 13. The screening frame 13 reciprocating left and right can also prevent the materials under the pushing port 3 from being accumulated at one position of the screen 15. The raw materials evenly distributed on the screen 15 can share the gravity of the raw materials. When the screening frame 13 reciprocates left and right, the raw materials above the screen 15 can be screened and fall on the inner side of the limit frame 12. The lower half of the limit frame 12 is contracted inwardly, which is convenient for collecting the screened raw materials from the bottom of the limit frame 12.

[0031] like Figure 1 and Figure 4As shown, a connecting belt 17 is fixedly connected to the top of the screen 15. When screening is completed, the side door on the left side of the screening box body 1 is opened, and the connecting belt 17 is pulled by hand. The left side of the screen 15 is rotatably connected to the screening frame 13. The connecting belt 17 will drive the screen 15 to rotate around the connection between the screening frame 13 and the screen 15, so that the right end of the screen 15 will rise, so that the crushed slag located above the screen 15 will roll to the left side of the screen 15, and the inner side of the screening frame 13 will be fixed. A baffle 16 is fixedly connected to the screen 15 to support the screen 15 to prevent the connecting belt 17 from being subjected to excessive pressure due to the screen 15 and the debris on the upper side of the screen 15, thereby breaking the connecting belt 17 and affecting the screening effect. When the debris moves to the left side of the screen 15, the connecting belt 17 is loosened, and the lower right side of the screen 15 is tightly fitted with the upper side of the baffle 16, so that the debris left by the screening can be taken out from the screening box body 1. The device is easy to use and simple to operate.
