Description

Technical Field

[0001] The utility model relates to the technical field of raw material mixing, in particular to a raw material mixing device used for the production and processing of lawn bricks. Background Art

[0002] In the production process of lawn bricks, mixing is an important step to fully mix the raw materials to form a uniform mixture;

[0003] Publication No. CN212680799U discloses a raw material mixing device for environmentally friendly brick production, including a sleeve, the outer side of the sleeve is fixedly connected to a support leg, and the inner side of the sleeve is fixedly connected to a round tube. The utility model stirs a large amount of raw materials at the axis of the round tube through a stirring rod, and at the same time, the raw materials in contact with the inner wall of the round tube are conveniently stirred through a spiral groove, and the stirring rod and the stirring tube rotate in opposite directions, so that the raw materials at the edge and center of the inner wall of the round tube can be fully stirred, and the stirring effect is better. Then, the stirring tube is equipped with a spiral groove to rotate the raw materials at the bottom of the inner wall of the round tube of the device clockwise, and the raw materials are transported to the top of the spiral groove along the spiral groove for extrusion and stirring. The inner wall of the round tube is conveniently scraped by the stirring tube, and the raw materials at the corner of the device are conveniently squeezed out to reduce the residual raw materials in the round tube. However, the patent still has the following problems in actual use:

[0004] After stirring the raw materials, the above-mentioned device will scrape off the residue on the inner wall through the stirring tube. However, when it is necessary to observe whether the interior is in a qualified residue-free state, it is often necessary to open the round cover, and the stirring parts such as the stirring tube and stirring rod will be lifted together with the round cover. At this time, the weight to be lifted is large, which makes it inconvenient for the staff to lift the round cover and observe the internal situation. In addition, the stirring tube and stirring rod will wear out with use. When maintenance is required, a large number of parts need to be disassembled and then the stirring tube and stirring rod need to be pulled out of the cylinder. The cylinder in actual production is large. The method of pulling out the stirring tube requires that the height of the production space is at least twice the height of the cylinder, which leads to limitations of the device.

[0005] A raw material mixing device for producing and processing lawn bricks is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the utility model is to provide a raw material mixing device for the production and processing of lawn bricks, so as to solve the problem that the stirring tube and the stirring rod mentioned in the above background technology wear out with use. When maintenance is required, a large number of parts need to be disassembled and then the stirring tube and the stirring rod need to be pulled out of the cylinder. However, the volume of the cylinder in actual production is relatively large. The method of pulling out the stirring tube requires that the height of the production space is at least greater than twice the height of the cylinder, which leads to limitations of the device.

[0029] The bottom surface of the driving gear 206 is fixedly connected to a driving shaft 207.

A lifting handle is installed on the top surface of the top cover 101. The lifting handle can assist the staff in moving the top cover 101, and the arc scraper 210 will scrape the material on the inner wall of the mixing bin 1.

The bottom of the gear bin 211 is fixedly connected with a supporting column 212 which is fixedly connected to the lower part of the inner part of the mixing bin 1 .

[0032] A screw bin 213 is fixedly connected to the lower part of the interior of the mechanical bin 201, and a bidirectional screw 214 is rotatably connected to the interior of the screw bin 213. A threaded sleeve 215 is symmetrically provided on the bidirectional screw 214, and a connecting column 216 is fixedly connected to the side of the threaded sleeve 215, and the connecting column 216 is slidingly connected to the screw bin 213; the other end of the connecting column 216 is fixedly connected to a clamping ring 217, and a ball 218 is rollingly installed on the inner arc surface of the clamping ring 217.

[0034] Working principle: Before using this raw material mixing device for lawn brick production and processing, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, when the device is working, the driving motor 202 will rotate the half gear ring 204 by letting the rotating disk 203 rotate, and by letting the half gear ring 205 rotate, thereby causing the driving gear 206 to rotate while driving the driving shaft 207 to rotate, and then causing the arc scraper 210 and the stirring crank 209 to rotate, and as the arc scraper 210 moves, the material on the inner wall of the mixing bin 1 will be scraped off, and the stirring crank 209 will stir the material;

[0035] When the half gear ring 204 is meshed with the driving gear 206, the driving shaft 207 drives the arc scraper 210 and the stirring crank 209 to rotate clockwise. When the half gear ring 204 is disengaged from the driving gear 206 and the half gear ring 205 is meshed with the driving gear 206, the driving shaft 207 drives the arc scraper 210 and the stirring crank 209 to rotate counterclockwise. The clockwise and counterclockwise rotation speeds of the stirring crank 209 are different, so that the material can be stirred in two directions, and when it is more uniform, it can also ensure that the arc scraper 210 fits the inner wall of the mixing bin 1 to make a complete circular motion.

[0036] When the driving shaft 207 rotates, the driving bevel gear 301 drives the driven gear 302 to rotate, and then the cross bar 303 drives the stirring blade 304 to rotate, and finally the raw materials at the bottom of the mixing bin 1 are stirred upwards, which increases the stirring efficiency and makes the stirring more uniform.

[0037] When maintenance or observation of the interior of the mixing bin 1 is required, first rotate the straight rod 219 to rotate the bidirectional screw 214, so that the threaded sleeve 215 drives the connecting column 216 to move horizontally, thereby moving the clamping ring 217 away from the driving shaft 207, and then lift the top cover 101 upward by pulling the handle to make the driving gear 206 disengage from the mechanical bin 201 through the through hole 208. At this time, the interior of the mixing bin 1 can be observed through the gap between the mixing bin 1 and the top cover 101, and when the parts inside the mixing bin 1 need maintenance, after the top cover 101 is removed, the staff can directly enter the mixing bin 1 and perform maintenance directly, avoiding the troublesome operation of taking out all the parts inside the mixing bin 1, reducing the space requirement when the device is used, and increasing the practicality of the device.
