Description

Technical Field

[0001] The utility model relates to the technical field of mortar production, in particular to a lifting device for mortar production. Background Art

[0002] Mortar is a material used in construction and repair projects, usually composed of water, sand and binders (such as cement or lime). Its function is to bond bricks, stones or other building materials together to form a solid structure. Mortar plays an important role in filling voids, fixing bricks and providing structural support in construction projects.

[0003] The Chinese patent with the publication number CN211599011U discloses a lifting device for mortar production. Through the setting of the screening net, when the mortar enters the lifting box from the feeding hopper, the filter screen blocks the large-particle impurities in the mortar, preventing the large-particle impurities from entering the interior of the lifting box and improving the quality of the mortar.

[0004] However, after screening the large-particle impurities in the mortar, the large-particle impurities accumulate on the surface of the filter screen, which will affect the fluidity of the mortar, resulting in a decrease in the flow rate of the mortar and affecting the production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lifting device for mortar production that can improve the flow rate of mortar during screening.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows.

[0007] A lifting device for mortar production includes a lifting box. A feeding hopper is installed on the outer surface of one side of the lifting box, and a discharge pipe is installed on the outer surface of the other side of the lifting box. Through slots are opened on both side walls of the feeding hopper, and a sieve plate is inserted into the two through slots. A contact plate is arranged on one side of the feeding hopper, a spring is connected to the outer surface of the contact plate, and a motor is installed on the outer surface of the lifting box on the other side of the feeding hopper. A cam is installed at the end of the output shaft of the motor.

[0008] Thus, since the sieve plate is inserted into the two through slots, it has mobility. When the motor drives the cam to rotate, the cam continuously presses the sieve plate, and the sieve plate is elastically acted upon by the spring. Therefore, the purpose of the reciprocating shaking of the sieve plate can be achieved. The shaking can promote the redistribution of particles on the surface of the sieve plate, enabling small particles to pass through the pores of the sieve plate smoothly, while large particles are blocked. And through continuous shaking, the accumulation of large-particle impurities on the sieve plate can be avoided, ensuring that the sieve plate maintains good permeability, reducing blockage phenomena, and by shaking the sieve plate, it can ensure that the fluidity of the mortar is not affected by the screening process, maintaining the stability and efficiency of the production process.

[0009] Further, a screw is rotatably connected to the outer surface of the feed hopper. A nut is installed on the outer surface of the screw. The nut is connected to the abutting plate. A U-shaped clamping plate is installed at the end of the spring, and the U-shaped clamping plate is adapted to the sieve plate.

[0010] When it is necessary to clean or replace the sieve plate, the screw can be rotated. The screw drives the nut to move away from the feed hopper, and then the U-shaped clamping plate can be driven to separate from the sieve plate. Then, the U-shaped clamping plate is rotated to the upper side, and the sieve plate is pulled out for cleaning or replacement. When installing the sieve plate, just insert the sieve plate into the through groove, make one end of the sieve plate abut against the cam, then rotate the U-shaped clamping plate to correspond to the sieve plate, and then rotate the screw in the opposite direction, so as to drive the U-shaped clamping plate to move towards the sieve plate and clamp on its outside, realizing the installation of the sieve plate.

[0011] Further, screw holes are formed on the outer surface of the screw. A fixing block is installed on the outer surface of the feed hopper. A bolt is installed inside the fixing block, and the bolt is adapted to the screw hole.

[0012] Through the arrangement of the screw hole and the bolt, the screw can be locked to avoid the situation that the screw loosens and reverses during use, driving the spring to reduce the elastic force applied to the sieve plate, which affects the screening effect of the mortar.

[0013] Further, a telescopic rod is installed on the outer surface of the abutting plate. The end of the telescopic rod is connected to the U-shaped clamping plate, and the spring is sleeved on the outer surface of the telescopic rod.

[0014] Through the arrangement of the telescopic rod, the reliability of the connection between the abutting plate and the U-shaped clamping plate can be improved, and the spring can be provided with a limiting and guiding effect to avoid the situation that the spring is bent and deformed, improving its service performance and life.

[0015] Further, a ball is arranged on the side of the sieve plate facing the cam, and the cam abuts against the ball.

[0016] Through the arrangement of the ball, the friction between the sieve plate and the cam can be reduced, wear and noise can be reduced, and the use is more smooth.

[0017] Further, two support columns are installed on the outer surfaces of both sides of the lifting box. A walking wheel is installed at the bottom of the support column.

[0018] Through the arrangement of the support column and the walking wheel, the device can be conveniently moved, improving the flexibility of use.

[0019] Further, the number of the screw holes is four, and the four screw holes are arranged in a coaxial array on the outer surface of the screw.

[0020] Through the arrangement of the four screw holes, the adjustment range for fixing the screw can be improved. When the elastic force of the spring decreases after long-term use, the adjustment accuracy of the compression amount of the spring can be improved.

[0021] Furthermore, the sieve plate is made of stainless steel.

[0022] Stainless steel has good corrosion resistance and can resist the chemical corrosion and oxidation that may exist in the mortar, thereby extending the service life of the sieve plate. Description of the Drawings

Detailed Description of the Preferred Embodiments

[0029] The present utility model will be described in detail below with reference to the accompanying drawings.

[0030] As Figures 1-5 shown, a lifting device for mortar production includes a lifting box 100. An outer surface of one side of the lifting box 100 is provided with a feed hopper 101, and an outer surface of the other side of the lifting box 100 is provided with a discharge pipe 102. Through grooves 103 are formed in both side walls of the feed hopper 101, and a sieve plate 104 is inserted into the two through grooves 103. An abutting plate 105 is arranged on one side of the feed hopper 101, a spring 106 is connected to an outer surface of the abutting plate 105, and a motor 107 is installed on the outer surface of the lifting box 100 on the other side of the feed hopper 101. An end of an output shaft of the motor

[107] is provided with a cam 108.

[0031] During use, after the mortar enters the feed hopper 101, it is screened by the sieve plate 104, and then lifted by the lifting box 100 and discharged from the discharge pipe 102. When screening the mortar through the sieve plate 104, the motor 107 can be started. The motor 107 drives the cam 108 to rotate. The convex surface of the cam 108 squeezes the sieve plate 104, causing the sieve plate 104 to move sideways and compress the spring 106. When the convex surface of the cam 108 separates from the sieve plate 104, the compressed spring 106 releases its elastic force, so it can push the sieve plate 104 back to its original position. Therefore, under the continuous rotation of the cam 108, the purpose of driving the sieve plate 104 to reciprocate and shake can be achieved, reducing the blockage of large particles. And by shaking the sieve plate 104, it can ensure that the fluidity of the mortar is not affected by the screening process, maintaining the stability and efficiency of the production process.

[0032] Specifically, a screw rod 200 is rotatably connected to the outer surface of the feed hopper 101. A nut 201 is installed on the outer surface of the screw rod 200. The nut 201 is connected to the abutting plate 105. The end of the spring 106 is installed with a U-shaped clamping plate 202, and the U-shaped clamping plate 202 is adapted to the sieve plate 104. When it is necessary to clean or replace the sieve plate 104, the screw rod 200 can be rotated. The screw rod 200 drives the nut 201 to move away from the feed hopper 101, and then it can drive the U-shaped clamping plate 202 to separate from the sieve plate 104. Then rotate the U-shaped clamping plate 202 to the upper side by an angle and draw out the sieve plate 104 for cleaning or replacement. When installing the sieve plate 104, just insert the sieve plate 104 into the through groove 103, make one end of the sieve plate 104 abut against the cam 108, then rotate the U-shaped clamping plate 202 to make it correspond to the sieve plate 104, and then rotate the screw rod 200 in the opposite direction, so as to drive the U-shaped clamping plate 202 to move towards the sieve plate 104 and clamp it on the outside, realizing the installation of the sieve plate 104.

[0033] Specifically, a threaded hole 300 is formed on the outer surface of the screw rod 200. A fixing block 301 is installed on the outer surface of the feed hopper 101. A bolt 302 is installed inside the fixing block 301, and the bolt 302 is adapted to the threaded hole 300. Through the arrangement of the threaded hole 300 and the bolt 302, the screw rod 200 can be locked to prevent the screw rod 200 from loosening and reversing during use and driving the elastic force exerted by the spring 106 on the sieve plate 104 to decrease, affecting the screening effect of the mortar.

[0034] Specifically, a telescopic rod 400 is installed on the outer surface of the abutting plate 105. The end of the telescopic rod 400 is connected to the U-shaped clamping plate 202, and the spring 106 is sleeved on the outer surface of the telescopic rod 400. Through the arrangement of the telescopic rod 400, the reliability of the connection between the abutting plate 105 and the U-shaped clamping plate 202 can be improved, and a limiting and guiding effect is provided for the spring 106, preventing the spring 106 from bending and deforming, and improving its service performance and life.

[0035] Specifically, a ball 500 is provided on the side of the sieve plate 104 facing the cam 108. The cam 108 abuts against the ball 500. Through the arrangement of the ball 500, the friction between the sieve plate 104 and the cam 108 can be reduced, wear and noise can be lowered, and the use is more smooth.

[0036] Specifically, two support columns are installed on the outer surfaces of both sides of the lifting box 100, and traveling wheels are installed at the bottoms of the support columns. Through the arrangement of the support columns and the traveling wheels, the device can be conveniently moved, and the flexibility of use is improved.

[0037] Specifically, the number of the screw holes 300 is four, and the four screw holes 300 are arranged coaxially and arrayed on the outer surface of the screw 200. Through the arrangement of the four screw holes 300, the adjustment range for fixing the screw 200 can be increased. When the elastic force of the spring 106 decreases after long-term use, the adjustment accuracy of the compression amount of the spring 106 can be improved.

[0038] Specifically, the material of the sieve plate 104 is stainless steel, and stainless steel has good corrosion resistance and can resist the chemical corrosion and oxidation that may exist in the mortar, thereby prolonging the service life of the sieve plate 104.

It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions.
