Technical Field

[0001] The present application relates to the technical field of sand and gravel separation, and in particular to a sand and gravel separator. Background Art

[0002] The sand and gravel separator is a kind of equipment used for fine screening of sand and stone. The sand and gravel separator is mainly composed of a feed trough and a mixing separator. In traditional work, the sand and gravel are poured into the feed trough, and then pass through the feed trough and enter the mixing separator for separation.

[0003] When pouring sand and gravel, workers use trucks to pour materials into the feed trough of the sand and gravel separator. Due to the fast speed, they are easily accumulated in the feed trough, causing blockage of the sand and gravel separator. Utility Model Content

[0004] In order to solve the problem that when sand and gravel are poured into the separator, the sand and gravel easily cause the sand and gravel separator to be blocked due to the fast feeding speed, the present application provides a sand and gravel separator.

[0005] The present application provides a sand and gravel separator, which adopts the following technical solution:

[0006] A sand and gravel separator comprises a frame, a feed trough and a stirring separator, wherein the feed trough is fixedly connected to the stirring separator, and is characterized in that a temporary storage bucket is arranged on the frame, a discharge pipe for conveying sand and gravel into the feed trough is arranged at the bottom of the temporary storage bucket, and the discharge pipe is provided with a valve for controlling the flow rate of sand and gravel.

[0007] By adopting the above technical solution, when pouring sand and gravel, the temporary storage bucket can store part of the sand and gravel, which to a certain extent prevents the sand and gravel from flowing into the feed trough too fast, causing the sand and gravel to block the mixing separator.

[0008] Furthermore, the frame includes a mounting platform and a load-bearing column, the mounting platform is fixedly arranged on the load-bearing column, the temporary storage bucket is fixedly arranged on the mounting platform, and the mounting platform is provided with a cleaning mechanism for cleaning the temporary storage bucket.

[0009] By adopting the above technical solution, when pouring sand and gravel into the temporary storage bucket, due to the heavy weight of the sand and gravel, in order to prevent the temporary storage bucket from having insufficient load capacity, it is necessary to increase the load-bearing capacity of the temporary storage bucket. By setting up a mounting platform, the load-bearing capacity of the temporary storage bucket is increased so that it can temporarily store a certain amount of sand and gravel without being damaged due to excessive load-bearing. At the same time, a cleaning mechanism is provided on the mounting platform to clean the temporary storage bucket.

[0010] Furthermore, the cleaning mechanism includes a brush plate, a cleaning plate and a driving assembly. The cleaning plate is arranged parallel to the inner wall of the temporary storage bucket.

When the limit block 923 slides along the limit groove 924, the limit block 923 is prevented from sliding out of the inner wall range of the sliding sleeve. A pressure-resistant plate is provided on the bottom wall of the protective plate 8, and the inner rod 921 is passed through the pressure-resistant plate. The pressure-resistant plate prevents excessive pressure between the inner rod 921 and the protective plate 8. The spring 91 is sleeved on the sleeve, and one end of the spring 91 abuts against the bottom wall of the mounting groove 31, and the other end abuts against the pressure-resistant plate.

[0042] The implementation principle of a sand and gravel separator in the embodiment of the present application is as follows: during the process of pouring sand and gravel, the temporary storage bucket 3 performs buffer storage on a part of the sand and gravel, to a certain extent preventing a large amount of sand and gravel from entering the feed trough 2 in a short time. When pouring, the sand and gravel are poured toward the protective plate 8, and the protective plate 8 moves downward after receiving the impact, and the spring 91 is compressed to buffer the force above, and the sand and gravel reaches the outlet below the feed trough 4 after passing through the feed pipe 4 downward. When pouring sand and gravel into the temporary storage bucket 3, if the speed of the sand and gravel entering the feed trough 2 is too fast at this time, the valve 5 is used to change the sand and gravel circulation speed, and the temporary storage bucket 3 can store a part of the sand and gravel at the same time, so as to prevent the sand and gravel from entering the feed trough 2 too fast, and to a certain extent prevent the mixing separator 1 from being blocked due to excessive sand and gravel flowing in a short time.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
