Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, in particular to a sand material blanking device for a mortar production line. Background Technique

[0002] Mortar is a commonly used material for masonry and plastering, which is made by mixing cement, lime or gypsum and other gelling materials with sand or slag and other fine aggregates and adding water. It is mainly used for masonry of masonry structures and plastering, etc. Premixed mortar refers to a semi-finished product formed by prior mixing. When in use, it is further stirred into a mortar finished product and then used. In the process of producing premixed mortar, after screening the sand material, a blanking device is needed to blank the sand material into a lifting mechanism, and then the lifting mechanism feeds the material for subsequent stirring work;

[0003] Due to its unique physical properties, that is, it becomes more viscous after mixing, mortar often faces the problem of blockage at the discharge port during the discharge process. Once the discharge port is blocked, it will directly affect the discharge efficiency of the mortar, reducing the production efficiency of the entire production line. In addition, in order to dredge the blocked discharge port, it is often necessary to stop the machine for cleaning, which not only increases the production cost, but also may cause additional wear and damage to the equipment. For this reason, we propose a sand material blanking device for a mortar production line to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sand material blanking device for a mortar production line to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sand material blanking device for a mortar production line, including a blanking hopper. Two side plates are welded to the top of the blanking hopper. The same cross plate is welded between the two side plates. Two guide rods are arranged on the cross plate. The bottom end of the guide rod is welded with a round block. A spring is welded between the top of the round block and the bottom of the cross plate. The spring is movably sleeved on the corresponding guide rod. The top ends of the two guide rods are welded with the same connecting plate. A ball is embedded in the top of the connecting plate. Two connecting rods are welded to the bottom of the connecting plate. The connecting rods are slidably connected with the cross plate. The end of the connecting rod is fixedly connected with an inserting rod. One side of one of the two side plates is fixedly connected with a support plate. A driving motor is fixedly connected to the top of the support plate. The output shaft of the driving motor is fixedly connected with an eccentric wheel. The eccentric wheel is slidably connected with the ball.

[0006] Further preferably, two L-shaped plates are fixedly connected to both sides of the blanking hopper. The same mounting plate is fixedly connected to the bottoms of the two L-shaped plates on the same side.

[0007] Further preferably, two mounting holes are formed in the mounting plate.

[0008] Further preferably, the bottom of the blanking hopper is provided with a conical part.

[0009] Further preferably, two guiding holes are formed in the cross plate, and the cross plate is slidably connected to the corresponding guiding rods through the guiding holes.

[0010] Further preferably, two limiting holes are formed in the cross plate, and the cross plate is slidably connected to the corresponding connecting rods through the limiting holes.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model fixes the blanking hopper to the place where it needs to be used, starts the driving motor to drive the eccentric wheel to rotate. When the eccentric wheel rotates in the first half turn, it squeezes the ball. Under the action of the squeezing force, the ball moves and rotates. The ball drives the connecting plate to move downward. The connecting plate drives the guiding rod to slide on the cross plate. The guiding rod drives the corresponding round block to move downward and stretch the spring. At the same time, the connecting plate drives the inserting rod to move downward through the connecting rod. When the eccentric wheel rotates to the second half turn, it gradually relaxes the squeezing of the ball. At this time, the spring in the stretched state resets. Under the action of the self-elastic force of the spring, the spring drives the corresponding guiding rod to move upward through the round block. The guiding rod drives the connecting rod to move through the connecting plate. The connecting rod drives the inserting rod to move upward, so that the inserting rod reciprocates up and down to dredge the discharging end of the blanking hopper and prevent blockage.
