Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel cleaning, in particular to an integrated sand and gravel cleaning machine for civil engineering. Background Art

[0002] Sand and gravel refer to a loose mixture of sand and crushed stone, which generally has strong resistance to weathering. In construction, sand and gravel are needed in most cases. Since sand and gravel itself is a mixture, it contains not only sand and crushed stone, but also a lot of soil. Before sand and gravel are used, they need to be screened and cleaned. First, the large pieces of soil mixed in the sand and gravel are removed, and then the soil attached to the surface of the sand and gravel is removed through cleaning. Therefore, a sand and gravel cleaning machine is needed to realize the cleaning process.

[0003] During use, the existing sand and gravel washing machine often only puts a sieve plate inside the machine body, then pours the sand and gravel onto the sieve plate, and then sprays water on the sand and gravel through a spray device to achieve the purpose of cleaning. Although this cleaning method can remove most of the mud, some mud blocks attached to the surface of the sand and gravel need to be removed with the help of external force. Therefore, for the mud blocks attached to the surface of the sand and gravel, the cleaning effect of the existing sand and gravel washing machine is limited, and the mud blocks attached to the surface of the sand and gravel cannot be completely cleaned. Utility Model Content

[0004] In view of the shortcomings of existing sand and gravel washing machines, the utility model provides a civil engineering sand and gravel washing all-in-one machine, which has the advantages of effectively removing mud attached to the surface of sand and gravel and screening the cleaned sand and gravel, solving the technical problems such as incomplete cleaning of mud attached to the surface of sand and gravel.

[0005] The utility model provides the following technical solution: a civil engineering sand and gravel cleaning integrated machine, including a support frame, and also including:

[0006] A cleaning cylinder is fixedly mounted on the top of the support frame, a waterproof box is fixedly mounted in the middle of the bottom surface of the inner cavity of the cleaning cylinder, a motor is fixedly mounted inside the waterproof box, a rotating shaft is fixedly connected to the output end of the motor, a spray device is movably sleeved on the top of the rotating shaft, a water inlet pipe is fixedly mounted in the middle of the top surface of the spray device, and a nozzle is fixedly mounted on the bottom surface of the spray device;

[0007] The sieve plate is movably sleeved on the outer surface of the rotating shaft, the inner cavity side wall of the cleaning cylinder is located at the lower side of the sieve plate and is fixedly installed with a receiving plate, the side wall of the cleaning cylinder is located at the receiving plate and is fixedly provided with a discharge port, and the bottom of the cleaning cylinder is fixedly provided with a water outlet pipe.

[0008] Preferably, the rotating shaft includes:

[0009] The reciprocating thread is arranged on the outer surface of the rotating shaft, and the sieve plate is connected with the rotating shaft through the reciprocating thread.

[0010] Preferably, the rotating shaft includes:

[0011] A fixed disk, fixedly sleeved on the outer surface of the rotating shaft and located at the lower side of the nozzle;

[0012] The water flow hole is arranged on the fixing plate.

[0013] Preferably, the sieve plate comprises:

[0014] A rubber ring, fixedly sleeved on the outer surface of the sieve plate;

[0015] The blocking strip is fixedly connected to the inner cavity side wall of the cleaning cylinder, and the blocking strip is located on the moving track of the rubber ring.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. Through the design of reciprocating threads, fixed plates and water holes, when sand and gravel are cleaned, the motor drives the shaft to rotate, so that the reciprocating threads on the shaft prompt the sieve plate to reciprocate up and down along the shaft. When the sand and gravel on the sieve plate contact the fixed plate, the sieve plate and the fixed plate squeeze the sand and gravel, causing friction between the sand and gravel. At this time, the water flow sprayed from the nozzle causes the mud attached to the surface of the sand and gravel to be rubbed off, thereby improving the effect of sand and gravel cleaning.

[0018] 2. By designing rubber rings and blocking strips, when the sieve plate is moved upward by the reciprocating thread on the rotating shaft, the rubber ring on the edge of the sieve plate will contact the blocking strip. At this time, if the sieve plate wants to continue to move upward, it must pass over the blocking strip. Therefore, the rubber ring on the edge of the sieve plate will be deformed and then pass over the blocking strip. After passing over the blocking strip, the rubber ring will recover from the deformed state, thereby generating vibration. At this time, the vibration of the rubber ring is used to drive the vibration of the sieve plate, thereby screening the cleaned sand and gravel. At the same time, the vibration of the sieve plate is also conducive to the separation of mud blocks and sand and gravel. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-Figure 3 The outer surface of the rotating shaft 5 is provided with a reciprocating thread 51, and the sieve plate 9 is connected to the rotating shaft 5 through the reciprocating thread 51, so as to ensure that when the rotating shaft 5 rotates, the sieve plate 9 can be driven by the reciprocating thread 51 to reciprocate up and down along the rotating shaft 5.

[0026] See also Figure 1-Figure 3 The outer surface of the rotating shaft 5 is located at the lower side of the nozzle 8 and is fixedly sleeved with a fixed plate 52. When the sieve plate 9 moves up with the sand and gravel and the sand and gravel contact the fixed plate 52, the sieve plate 9 and the fixed plate 52 apply pressure to the sand and gravel, so that friction is generated between the sand and gravel, thereby scrubbing the mud attached to the surface of the sand and gravel. A water flow hole 53 is opened on the fixed plate 52 to facilitate the water flow to act on the sand and gravel for cleaning.

[0027] See also Figure 1-Figure 3A rubber ring 91 is fixedly sleeved on the outer surface of the sieve plate 9, and a blocking bar 92 is fixedly connected to the inner cavity side wall of the cleaning cylinder 2. The blocking bar 92 is located on the moving track of the rubber ring 91 to ensure that when the sieve plate 9 moves upward, when the sieve plate 9 passes over the blocking bar 92, the rubber ring 91 is deformed and vibrates, thereby screening the sand and gravel.

[0028] Working principle: when the sand and gravel need to be cleaned, the sand and gravel are poured into the interior of the cleaning cylinder 2 so that the sand and gravel fall on the sieve plate 9, and then the water flow is introduced into the spray device 6 through the water inlet pipe 7, and the spray device 6 is turned on so that the water flow is sprayed on the fixed plate 52 from the nozzle 8, and finally the water flows out through the water flow hole 53 to act on the sand and gravel, and then the motor 4 is turned on, and the motor 4 drives the rotating shaft 5 to rotate. During the rotation process, the rotating shaft 5 uses the design of the reciprocating thread 51 to make the sieve plate 9 reciprocate up and down along the reciprocating thread 51 on the rotating shaft 5. During the upward movement of the sieve plate 9, when the sand and gravel on the sieve plate 9 contacts the fixed plate 52, the sieve plate 9 and the fixed plate 52 will exert pressure on the sand and gravel, so that the sand and gravel will be rubbed, and then the friction between the sand and gravel will be used to cause the mud blocks attached to the surface of the sand and gravel to fall off, and at the same time, when the sieve plate 9 moves up, the rubber ring 91 on the edge of the sieve plate 9 will contact the blocking bar 92 The sieve plate 9 is moved downward to the lowest stroke by the reciprocating thread 51 on the rotating shaft 5, and the distance between the sieve plate 9 and the inner wall of the cleaning cylinder 2 is increased. At this time, the inclination of the surface of the sieve plate 9 is used to cause the cleaned sand and gravel to fall onto the receiving plate 10, and finally the cleaned sand and gravel will be discharged through the discharge port 11, and the water flow for cleaning the sand and gravel will form muddy water between the mud and the soil and be discharged from the water outlet pipe 12.
