Description

Unloading device for aggregate bin of concrete mixing station

technical field

The utility model belongs to the technical field of concrete mixing plants, in particular to a material-cutting device for an aggregate bin of a concrete mixing plant.

Background technique

With the rapid development of the construction industry, concrete has become the main raw material of the construction industry. At present, the working principle of the aggregate bin feeding device of the concrete mixing station: the sand and gravel aggregate in the growing concrete is fed through the aggregate bin to the conveying device below, and then transported to the concrete mixer through the conveying device, but the actual production of concrete Large pieces of sand and gravel that exceed the mixing standard may be mixed in, which will inevitably affect the quality of concrete.

Utility model content

The technical problem to be solved by the utility model is: to provide a feeding device for the aggregate bin of a concrete mixing station, which can avoid mixing sand and gravel that does not meet the mixing standard during the mixing process, thereby ensuring the quality of the concrete.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A feeding device for an aggregate bin of a concrete mixing station, comprising an aggregate bin and an aggregate conveying device, a crushing chamber is arranged above the aggregate bin, a feeding port is arranged on the top of the crushing chamber, and the crushing chamber There is a crushing roller inside; a screen is set between the crushing chamber and the aggregate bin.

As an improved technical solution, buffer plates are respectively provided on both sides of the inner wall of the aggregate bin.

As an improved technical solution, the aggregate conveying device is an aggregate conveying belt.

As an improved technical solution, the aggregate conveyor belt is provided with two layers, wherein the upper conveyor belt is a filter screen, and the discharge end is located at the inlet of the recovery tank; the discharge end of the lower conveyor belt is located at the aggregate of the mixer. Inlet.

As an improved technical solution, the filter net is electrically connected with a vibrating motor.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

In the utility model, a crushing chamber is arranged above the aggregate bin, a feeding port is arranged on the top of the crushing chamber, and crushing rollers are arranged inside the crushing chamber; a screen is provided between the crushing chamber and the aggregate bin. The sand and gravel enter the crushing chamber, and the large pieces of sand and gravel can be crushed by the action of the crushing roller, and then screened through the screen, and the sand and gravel that meets the mixing standard fall into the aggregate bin, and then used to prepare concrete. Utilizing the crushing rollers and screens in the crushing chamber of the utility model can prevent sand and stones that do not meet the mixing standard from entering the mixer and affecting the quality of concrete.

Because there are buffer plates on both sides of the inner wall of the aggregate bin. The buffer plate can prevent the sand and gravel aggregates from freely falling into the aggregate bin, and can evenly disperse the sand and gravel aggregates in the aggregate bin.

Since the aggregate conveying device is an aggregate conveyor belt, the sand in the aggregate bin can be transported to the mixer through the aggregate conveyor belt to produce concrete.

Since the aggregate conveyor belt has two layers, the upper conveyor belt is a filter screen, and the discharge end is located at the feed inlet of the recovery tank; the discharge end of the lower conveyor belt is located at the aggregate feed inlet of the mixer. This setting can further screen the sand and gravel. The sand and gravel that do not meet the mixing standard are transported to the crushing chamber through the upper conveyor belt for crushing, and the lower conveyor belt transports the sand and gravel that meets the mixing standard to the mixer.

Because the filter screen is electrically connected with a vibrating motor, the vibrating motor can promote sand and gravel that meet the standards to fall on the lower conveyor belt, which is convenient for sand and gravel to be screened.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figure 1, a feeding device for the aggregate bin of a concrete mixing station includes an aggregate bin 1 and an aggregate conveying device. A crushing chamber 2 is provided above the aggregate bin 1, and a feeding A crushing roller 22 is provided inside the crushing chamber 2; a screen 3 is provided between the crushing chamber 2 and the aggregate bin 1.

The working principle of the utility model: the aggregate of sand and gravel enters the crushing chamber 2 from the feed port 21, and after the action of the crushing roller 22, the sand and gravel with a large diameter can be crushed, and then the sand and gravel are screened by the screen 3, and the sand and gravel The stones slowly enter the aggregate bin 1, disperse evenly, and finally are transported to the mixer by the conveyor belt for the production of concrete.

As an improvement, buffer plates 4 are respectively provided on both sides of the inner wall of the aggregate bin 1 . The sand screened by the sieve enters the aggregate bin, and when passing through the buffer plate 4, the sand can be prevented from falling freely, ensuring that the sand is evenly dispersed in the aggregate bin 1.

As an improvement, the aggregate conveying device is an aggregate conveyor belt. The sand falls from the aggregate silo onto the aggregate conveyor belt, and is transported to the mixer by the conveyor belt.

As an improvement, as shown in Figure 2, the aggregate conveyor belt is provided with two layers, wherein the upper conveyor belt 5 is a filter screen, and the discharge end is located at the inlet of the recovery tank; the discharge end of the lower conveyor belt 6 is located at the mixer aggregate feed port. The gravel falls from the aggregate bin 1 onto the upper conveyor belt 5 first, and part of the gravel will pass through the filter hole and fall onto the lower conveyor belt 6. The gravel on the upper conveyor belt 5 is transported to the recovery tank, and then passed through the Reach the crushing chamber for crushing again for concrete production. The gravel on the lower conveyor belt 6 is directly transported into the mixer for mixing for concrete production.

As an improvement, the filter screen is electrically connected with a vibrating motor 7, and through the action of the vibrating motor 7, the sand meeting the stirring standard falls on the lower conveyor belt, which ensures the screening of the sand.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
