Description

Technical Field

[0001] The utility model relates to the field of house construction, in particular to a sand screening device used for house construction. Background Art

[0002] After searching for Chinese patents, the publication number is: CN217646828U, an efficient sand screening device for housing construction engineering construction, including a movable mobile frame, a sieve plate for screening sand is arranged on the upper side of the mobile frame, and an adjustment frame for supporting and lifting the right end of the sieve plate is arranged at the right end of the mobile frame, the lower end of the adjustment frame is rotatably connected to the mobile frame, and the adjustment frame can be locked and fixed after rotation and adjustment, and the rotation angle of the adjustment frame is adjusted to achieve support at different heights of the right end of the sieve plate, making the adjustment of the screening angle of the sieve plate more convenient, and when not in use, the adjustment frame is rotated to a horizontal state, and the sieve plate is also rotated to a horizontal state, completing the folding of the sand screening device and reducing the occupied space.

[0003] The existing screening devices have low screening efficiency. Generally, screening devices use vibration screening to screen sand. When screening, the sand is placed on the screen and piled together. It takes a long time to vibrate to disperse the sand, so the screening efficiency is low, which affects the work efficiency. It also does not have the bulk material function. Generally, the screening device directly pours the sand on the screen for screening. The sieves will pile up together on the screen. During the screening process, the sand is difficult to disperse, which affects the screening quality. In order to solve the above problems, we propose a sand screening device for house construction. Utility Model Content

[0004] The utility model aims to provide a sand screening device for house construction, which has the advantages of high screening efficiency and bulk material function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a sand screening device for house construction, comprising a base frame, a first motor is bolted to the bottom of the base frame, the output end of the first motor passes through the base frame and is fixedly sleeved with a turntable, the surface of the turntable is rotatably connected to a transmission rod, the other end of the transmission rod is hinged to a base frame, a sliding mechanism is arranged between the base frame and the base frame, a fixed frame is bolted to the top of the base frame, a screen is bolted between the inner walls of the fixed frame, a vibrator is bolted to the surface of the feed hopper, a feed hopper is bolted between the inner walls of the fixed frame, a second motor is bolted to the surface of the feed hopper, the output end of the second motor passes through the feed hopper and is connected to a rotating shaft through a coupling, and the other end of the rotating shaft is rotatably connected to the inner wall of the feed hopper, and a first spiral blade and a second spiral blade are welded to the surface of the rotating shaft.

[0006] By adopting the above technical scheme, the turntable is driven to rotate by the rotation of the first motor, and the rotation of the turntable drives one end of the transmission rod to rotate. The rotation of one end of the transmission rod causes the other end of the transmission rod to drive the bottom frame to move back and forth. The reciprocating movement of the bottom frame drives the fixed frame to make the screen move back and forth for screening. In combination with the vibration of the vibrator, the purpose of high screening efficiency can be achieved, and the sliding speed of sand is increased, thereby improving the screening efficiency. By pouring sand into the feed hopper, the rotation of the second motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the first spiral blade and the second spiral blade to rotate. Since the spiral directions of the first spiral blade and the second spiral blade are opposite, the sand will be transported to both sides and the sand will be dispersed, thereby achieving the purpose of bulk material, improving the screening speed and ensuring the screening quality.

[0007] The utility model is further configured as follows: the sliding mechanism includes a slide groove, the slide groove is opened on the top of the bottom frame, a slider is slidably connected inside the slide groove, a support rod is bolted to the top of the slider, and the top of the support rod is bolted to the bottom of the bottom frame.

[0008] By adopting the above technical solution, the fixed frame is fixed by setting a sliding mechanism, so as to ensure that the fixed frame is not loose when moving and ensure stability.

[0009] The utility model is further configured as follows: a protective shell is bolted to the top of the base frame, and the turntable is located inside the protective shell.

[0010] By adopting the above technical solution, a protective shell is provided to protect the turntable, thereby improving production safety.

[0011] The utility model is further configured that: the spiral directions of the first spiral blade and the second spiral blade are opposite.

[0012] By adopting the above technical solution, the spiral directions of the first spiral blade and the second spiral blade are arranged to be opposite, which facilitates the dispersing of materials.

[0013] The utility model is further configured as follows: the bottom of the base frame and the surface of the feed are both bolted with a protective shell, and the first motor and the second motor are both located inside the protective shell.

[0014] By adopting the above technical solution, the first motor and the second motor are protected by providing a protective shell.

[0015] The utility model is further configured as follows: a backing plate is bolted to the bottom of the base frame.

[0016] By adopting the above technical solution and providing a pad, the stability of the device is improved.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model drives the turntable to rotate by the rotation of the first motor, and the rotation of the turntable drives one end of the transmission rod to rotate, and the rotation of one end of the transmission rod causes the other end of the transmission rod to drive the bottom frame to move back and forth, and the reciprocating movement of the bottom frame drives the fixed frame to make the screen move back and forth for screening, and the vibrating mode of the vibrator can achieve the purpose of high screening efficiency, increase the sliding speed of sand, and thus improve the screening efficiency;

[0019] 2. The utility model pours sand into the feed hopper, and the second motor rotates to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the first spiral blade and the second spiral blade to rotate.
