Description

Technical Field

[0001] This utility model relates to the field of dry-mixed mortar technology, specifically to a sieving and lifting device for dry-mixed mortar. Background Technology

[0002] Dry-mixed mortar is a cement-based or gypsum-based building material that is pre-mixed evenly in a factory. It consists of precisely proportioned cementitious materials, reasonably graded aggregates, and functional additives. It completely solves the problems of unstable quality, low efficiency, and serious environmental pollution that exist in traditional on-site mixed mortar. In the production process of dry-mixed mortar, the raw materials need to be lifted and screened to ensure product quality.

[0003] Currently, when using screening and lifting devices, a synchronous screening mechanism is lacking. The lifting and screening of dry-mixed mortar are usually completed by separate equipment. That is, the raw material is first lifted to a certain height by a hoist and then transported to the screening equipment for screening. This results in a large equipment footprint, requires additional conveying equipment to connect the hoist and the screening equipment, and the lifting and screening processes are carried out in separate steps, resulting in low production efficiency. Therefore, a screening and lifting device for dry-mixed mortar is proposed to add a synchronous screening mechanism. By using guiding, rotation, and displacement methods, screening is carried out simultaneously during the lifting of dry-mixed mortar. This not only reduces the size of the device but also helps to improve the processing efficiency of dry-mixed mortar, thereby improving the performance. Utility Model Content

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To facilitate simultaneous screening during the lifting process of dry-mixed mortar, thereby improving its performance, such as... Figure 1-3 As shown, the present invention provides a screening and lifting device for dry-mixed mortar, comprising a base 1, a screening component 3, and a driving component 4. A support frame 2 is bolted to the top of the base 1. The screening component 3 is disposed on one side of the support frame 2, the driving component 4 is disposed on one side of the screening component 3, a recycling component 5 is disposed on the other side of the screening component 3, and a material collection component 6 is disposed at the bottom of the screening component 3.

[0026] The drive assembly 4 includes a sliding frame 401, which is slidably connected to the support frame 2. A rotating roller 402 is installed inside the sliding frame 401 via bearings. The two ends of the rotating roller 402 are located outside the sliding frame 401 and are connected to a turntable 403 by bolts. A rocker arm 404 is rotatably connected to the outside of the turntable 403 via a rotating shaft. A transmission gear 405 is fixedly sleeved inside the sliding frame 401 around the rotating roller 402. A rack 7 corresponding to the transmission gear 405 is connected to the top surface of one side of the support frame 2 by bolts.

[0027] In use, a synchronous screening mechanism is added through the support frame 2, sliding frame 401, rotating roller 402, turntable 403, rocker arm 404, transmission gear 405 and rack 7. By using lifting, rotation and displacement, the screening process can be carried out simultaneously during the lifting of dry mixed mortar.

[0028] To improve usability, for example, such as Figure 2 , Figure 4 As shown, the present invention also includes the following: the recycling component 5 includes a flow guide 501, an exhaust fan 502 is bolted to the outside of the flow guide 501, and the air inlet of the exhaust fan 502 is located inside the flow guide 501; the bottom of the flow guide 501 is bolted to a recycling trough 503.

[0029] During use, the dust generated during the lifting and screening process is recovered by using the guide channel 501, the exhaust fan 502, and the recovery tank 503, which can reduce environmental pollution.

[0030] For example, such as Figure 2 , 3 As shown, the present invention also includes a fixed column 406 sleeved on the other end of the rocker arm 404, a notch 407 corresponding to the rack 7 on one side of the sliding frame 401, the screening assembly 3 including a U-shaped frame 301, and the sliding frame 401 being bolted to the U-shaped frame 301, a screen box 302 being slidably connected inside the U-shaped frame 301, and the fixed column 406 being bolted to the screen box 302, and a cover plate 303 being rotatably connected to the top of the U-shaped frame 301 via a damping shaft.

[0031] In use, the fixed column 406 facilitates the connection of one end of the rocker arm 404 to the screen box 302. Through the U-shaped frame 301, the screen box 302 and the cover plate 303, the material can be screened by reciprocating sliding. The top and bottom of the U-shaped frame 301 and the screen box 302 are both provided with openings, and a screen is fixedly installed inside the screen box 302.

[0032] For example, such as Figure 4As shown, the present invention also includes a filter plate 504 fixedly installed on one side of the flow guide 501 through a slot, and an oblique opening 505 is provided at the bottom of the flow guide 501 on one side of the filter plate 504, and the oblique opening 505 is connected to the recycling trough 503.

[0033] During use, the filter plate 504 and the inclined plate 505 facilitate the filtration and recycling of dust.

[0034] For example, such as Figure 5 As shown, the present invention also includes the following: the material collection assembly 6 includes a mounting frame 601, a receiving hopper 602 is provided between the mounting frames 601, a support rod 603 is welded to one side of the receiving hopper 602, and the support rod 603 is rotatably connected to the mounting frame 601 through a rotating shaft, and a rotary motor 604 is bolted to the surface of the mounting frame 601, and the rotary motor 604 is connected to the support rod 603 through a drive shaft.

[0035] In use, the mounting frame 601, receiving hopper 602, support rod 603 and rotary motor 604 can be used to tilt the screened material to assist in unloading.

[0036] For example, such as Figure 6 As shown, the present invention also includes a ball screw 201 installed in the support frame 2 via bearings, a corresponding nut seat 202 sleeved around the ball screw 201, and the nut seat 202 connected to the sliding frame 401 by bolts. A servo motor 203 is bolted to the top of the support frame 2, and the servo motor 203 is connected to the ball screw 201 via a drive shaft.

[0037] In use, the ball screw 201, nut seat 202 and servo motor 203 can drive the material to perform lifting action. The ball screw 201 includes a telescopic protective cover, the base 1 includes a controller, and the servo motor 203, exhaust fan 502 and rotary motor 604 are electrically connected to the controller through wires.

[0038] In use, the operator first opens the cover plate 303 and introduces the dry-mixed mortar into the screen box 302. The servo motor 203 drives the ball screw 201 to rotate, and the nut seat 202 drives the sliding frame 401 and the U-shaped frame 301 to lift vertically upward. At the same time, the rack 7 drives the rotating roller 402 to rotate through the meshing transmission gear 405. The turntable 403 drives the rocker arm 404 to rotate, so that the screen box 302 moves horizontally back and forth. The material is screened through the screen in the screen box 302. The screened material falls into the bottom receiving hopper 602 through the opening to complete the screening and recycling. When it is lifted to the designated height, the rotary motor 604 drives the support rod 603 to rotate, and the receiving hopper 602 tilts downward so that the recycled mortar can fall into the vehicle body to complete the unloading.

[0039] While unloading, the negative pressure generated by the exhaust fan 502 can be used to draw the dust generated during the unloading process into the guide trough 501 and the recovery trough 503 for recovery. This not only reduces pollution in the working environment, but also greatly reduces the waste of material resources, making it easier to recycle and reuse in the future. The overall structure is simple and easy to operate, and it is more convenient and reliable to use.
