Description

Technical Field

[0001] This utility model belongs to the field of dry-mixed mortar production equipment, and in particular relates to a dry-mixed mortar feeding device. Background Technology

[0002] Dry-mixed mortar refers to a granular or powdery material that is physically mixed with aggregates, inorganic cementitious materials, and additives that have undergone drying and screening in a certain proportion. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water.

[0003] There are two main methods for feeding raw materials into dry-mixed mortar: U-shaped trough belt conveyors and pneumatic conveying systems. U-shaped trough belt conveyors are used to feed sand raw materials to reduce friction, while pneumatic conveying systems are used to feed powder raw materials.

[0004] When feeding sand and gravel raw materials, workers use a loader to dump the stockpiled sand and gravel into the hopper of a U-shaped trough belt conveyor. While this feeding method can achieve the feeding of sand and gravel raw materials, it has the following technical problems: 1. High feeding cost: It requires not only a loader but also a dedicated driver to operate the equipment; 2. Low efficiency: Because the loader needs to move back and forth during operation, and the U-shaped trough belt conveyor is highly efficient, the material is often transported before the next scoop is placed; 3. High labor intensity: To coordinate with the operation of the U-shaped trough belt conveyor, the driver needs to operate the loader quickly, resulting in high labor intensity during the feeding period. Utility Model Content

[0005] This invention addresses the technical problems existing in the supply of sand raw materials in dry-mixed mortar by proposing a dry-mixed mortar material supply device that is reasonably designed, simple in structure, easy to process, and capable of automatically supplying materials to a U-shaped trough belt conveyor.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a dry-mixed mortar feeding device, including a U-shaped trough belt conveyor and a foundation pit. One end of the U-shaped trough belt conveyor is located in the foundation pit. The U-shaped trough belt conveyor is located at one end of the foundation pit. Sand and gravel side retaining walls are provided on both sides of the foundation pit. A tipping plate is provided on the top of the foundation pit. A crossbeam is provided on the top of the foundation pit. The crossbeam is located close to the U-shaped trough belt conveyor. The end of the tipping plate near the crossbeam is hinged to the crossbeam. A hydraulic cylinder for driving the tipping plate to tilt is provided in the foundation pit. A discharge plate is provided at the end of the crossbeam away from the tipping plate. The discharge plate is located above the U-shaped trough belt conveyor. End retaining walls are also provided on the crossbeam. The end retaining walls are located on both sides of the discharge plate.

[0007] Preferably, an auxiliary gate is provided above the unloading plate, and the auxiliary gate is located between the two end retaining walls.

[0008] Preferably, the unloading plate is hinged to the crossbeam, and a telescopic cylinder is provided at the bottom of the unloading plate away from the crossbeam, with the telescopic cylinder located on both sides near the unloading plate.

[0009] Preferably, the pit is arranged in a convex shape.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1 , Figure 2 As shown, this embodiment provides a dry-mixed mortar feeding device, including a U-shaped trough belt conveyor 1 and a foundation pit, which is a pit dug below the ground surface. The purpose of the foundation pit is to reduce the feeding height of the U-shaped trough belt conveyor 1 so as to facilitate automatic feeding.

[0017] One end of the U-shaped trough belt conveyor 1 is set inside the foundation pit. The U-shaped trough belt conveyor 1 is set at an upward inclination. The U-shaped trough belt conveyor 1 is set at one end of the foundation pit. Sand and gravel side retaining walls 4 are set on both sides of the foundation pit. The sand and gravel side retaining walls 4 are set mainly to limit the sand and gravel and prevent it from moving to both sides.

[0018] A tipping bucket 3 is installed at the top of the pit, with both ends of the tipping bucket 3 close to the side retaining wall 4 for sand and gravel. A crossbeam 2 is also installed at the top of the pit, close to the U-shaped trough belt conveyor 1. The end of the tipping bucket 3 closest to the crossbeam 2 is hinged to the crossbeam 2, meaning the tipping bucket 3 covers the end of the pit furthest from the crossbeam 2. In this way, the tipping bucket 3 is used to place sand and gravel.

[0019] A hydraulic cylinder 31 is installed in the pit to drive the tipping plate 3 to rotate. In this way, the hydraulic cylinder 31 can lift the sand and gravel and roll it onto the U-shaped trough belt conveyor 1 to complete the automatic feeding. The price of the hydraulic system is also much lower than that of the loader, which not only saves the labor but also reduces the cost.

[0020] To ensure the accurate dropping of sand and gravel, a discharge plate 7 is provided at the end of the crossbeam 2 away from the tipping plate 3. The discharge plate 7 is located above the U-shaped trough belt conveyor 1 and serves as a guide plate. To ensure that the sand and gravel move towards the discharge plate 7, an end retaining wall 5 is also provided on the crossbeam 2. The end retaining walls 5 are located on both sides of the discharge plate 7.

[0021] To further prevent the sand and gravel from moving around randomly, an auxiliary gate 6 is installed above the unloading plate 7, between the two end retaining walls 5. The auxiliary gate 6 is mainly designed to prevent sand and gravel from rolling down through the gap when there is too much sand and gravel accumulated in the space.

[0022] To further facilitate the movement of sand and gravel, the unloading plate 7 is hinged to the crossbeam 2. A telescopic cylinder 71 is installed at the bottom of the unloading plate 7 away from the crossbeam 2, with the telescopic cylinder 71 positioned near both sides of the unloading plate 7. Thus, the reciprocating motion of the telescopic cylinder 71 vibrates the sand and gravel above it, thereby promoting the movement of the sand and gravel.

[0023] To further reduce costs, in this embodiment, the foundation pit is arranged in a convex shape. Of course, the crossbeam 2 has no gaps. Alternatively, the crossbeam 2 could also be a wall.

[0024] To further ensure the movement of sand and gravel, guide ramps are provided on both the side retaining wall 4 and the end retaining wall 5 of the sand and gravel.

[0025] In this way, automatic feeding can be achieved by continuously adjusting the tilt height of the tipping plate 3 during use.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
