Description

Technical Field

[0001] This utility model belongs to the field of feeding devices, specifically relating to a feeding device for dry-mixed mortar equipment. Background Technology

[0002] Dry-mixed mortar, as an important building material, is widely used in wall plastering, floor leveling, and exterior wall insulation projects. It is typically composed of cement, sand, fillers, and various additives mixed in specific proportions, making it easy to transport, store, and apply. In modern construction projects, equipment using dry-mixed mortar has become standard equipment to improve construction efficiency and ensure mortar quality.

[0003] In existing dry-mixed mortar feeding devices, the hopper is usually inserted into the raw material pile of dry-mixed mortar. As the traction component rises, the hopper scoops up the raw material and lifts it to a certain height. Then, the raw material is discharged into the subsequent feeding pipe or storage bin through the discharge port at the top.

[0004] Due to the complexity of the mining site environment, the raw materials contain a large number of oversized stones and other impurities. During the feeding process, due to the lack of fine screening of the raw materials, these impurities will enter the production equipment along with the raw materials, which may lead to problems such as the mortar's strength, water retention, and adhesion not meeting the standards. Utility Model Content

[0005] To overcome the problem that existing dry-mixed mortar feeding devices lack fine screening of raw materials, allowing impurities to enter the production equipment along with the raw materials, which may lead to substandard key performance indicators such as mortar strength, water retention, and adhesion, a new feeding device for dry-mixed mortar equipment is proposed.

A sealing plate is slidably provided on the inner wall of the first trough. A pulley is fixedly connected to the outer wall of the two first rotating rods. A transmission belt is provided on the inner wall of the pulley.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment: a feeding device for a dry-mixed mortar equipment, including a feeding box 1; it also includes a first rotating rod 101 and a feeding assembly; two first rotating rods 101 are rotatably arranged on the inner wall of the feeding box 1; a first motor 102 is fixedly connected to the right end of the feeding box 1; the first rotating rod 101 located on the front side is fixedly connected to the output end of the first motor 102; two cams 103 are fixedly connected to the outer wall of the first rotating rod 101; mounting plates 104 are fixedly connected to the left and right ends of the inner wall of the feeding box 1; a screen plate 105 is slidably arranged on the inner wall of the feeding box 1; and multiple springs 1 are fixedly connected between the screen plate 105 and the mounting plate 104. 06. A feed pipe 107 is fixedly connected to the upper end of the feed box 1. The feed box 1 is equipped with a feeding assembly. By starting the first motor 102, the first rotating rod 101 is driven to rotate. The first rotating rod 101 drives the cam 103 to rotate. The protruding end of the cam 103 will intermittently push the screen plate 105 to move upward. Under the action of the spring 106, the screen plate 105 will vibrate, thereby screening the raw materials. This solves the problem that due to the lack of fine screening of raw materials, impurities will enter the production equipment with the raw materials, which may lead to the failure of key performance indicators such as strength, water retention and adhesion of mortar to meet the standards.

[0022] Please see Figures 1-3 In this embodiment, a first groove 2 is provided through the left end of the feed box 1. The lower end of the inner wall of the first groove 2 is flush with the upper end of the screen plate 105. A sealing plate 3 is slidably provided on the inner wall of the first groove 2. A pulley 4 is fixedly connected to the outer wall of the two first rotating rods 101. A transmission belt 5 is provided on the inner wall of the pulley 4. A feeding hopper 6 is fixedly connected to the lower end of the feed box 1. A discharge pipe 7 is fixedly connected to the lower end of the feeding hopper 6. A support column 8 is fixedly connected to the outer wall of the feeding hopper 6. A support plate 9 is fixedly connected to the lower end of the support column 8. After feeding is completed, the sealing plate 3 can be removed to easily remove the impurities remaining on the surface of the screen plate 105, so as to avoid affecting the subsequent screening effect.

[0023] Please see Figure 4 and Figure 5In this embodiment, the feeding assembly includes a second rotating rod 201. The second rotating rod 201 is rotatably mounted on the top of the inner wall of the feeding box 1. A second motor 202 is fixedly connected to the upper end of the feeding box 1. A screen plate 105 is slidably mounted on the outer wall of the second rotating rod 201. The second rotating rod 201 is fixedly connected to the output end of the second motor 202. The second motor 202 is used to drive the second rotating rod 201 to rotate. A baffle 203 is fixedly mounted on the lower end of the second rotating rod 201. A plurality of first discharge holes 204 are opened through the upper end of the baffle 203. The plurality of first discharge holes 204 are circumferentially distributed on the upper end of the baffle 203. A plurality of stirring plates 205 are fixedly mounted on the outer wall of the second rotating rod 201. The stirring plates 205 are inclinedly mounted on the outer wall of the second rotating rod 201. A bottom plate 206 is fixedly mounted on the inner wall of the discharge pipe 7. The upper end of the bottom plate 206 is... A second discharge hole 207 is provided, with the same diameter as the first discharge hole 204. Multiple scrapers 208 are fixed to the outer wall of the second rotating rod 201. The scrapers 208 are arc-shaped, and their lower end faces are in contact with the upper end faces of the bottom plate 206. By starting the second motor 202, the second rotating rod 201 is driven to rotate, causing the mixing plate 205 to agitate the raw materials, thus preventing the mortar from being unable to be discharged due to the interaction of internal particles. During discharge, the baffle 203 rotates under the drive of the second rotating rod 201, thereby causing the first discharge hole 204 and the second discharge hole 207 to be intermittently matched, achieving quantitative discharge of raw materials. Under the rotation of the scrapers 208, the residual raw materials on the surface of the bottom plate 206 can be scraped off, avoiding waste of raw materials.

[0024] In use, the raw material is first conveyed into the feed box 1 through the feed pipe 107. The raw material will fall onto the upper end of the screen plate 105. At this time, the first motor 102 is started to drive the first rotating rod 101 to rotate. The first rotating rod 101 drives the cam 103 to rotate. The protruding end of the cam 103 will intermittently push the screen plate 105 to move upward. Under the action of the spring 106, the screen plate 105 will vibrate, thereby screening the raw material and removing impurities from the raw material.

[0025] After screening, the raw materials fall into the hopper 6. The second motor 202 is started to drive the second rotating rod 201 to rotate, which causes the mixing plate 205 to agitate the raw materials. This prevents the mortar from being unable to be discharged due to the interaction of internal particles. During discharge, the baffle 203 rotates under the drive of the second rotating rod 201, so that the first discharge hole 204 and the second discharge hole 207 are intermittently matched to achieve quantitative discharge of raw materials. Under the rotation of the scraper 208, the residual raw materials on the surface of the bottom plate 206 can be scraped off to avoid waste of raw materials.

[0026] Through the above steps, the first motor 102 is started to drive the first rotating rod 101 to rotate. The first rotating rod 101 drives the cam 103 to rotate. The protruding end of the cam 103 will intermittently push the screen plate 105 to move upward. Under the action of the spring 106, the screen plate 105 will vibrate, thereby screening the raw materials. This solves the problem that due to the lack of fine screening of raw materials, impurities will enter the production equipment along with the raw materials, which may lead to the failure of key performance indicators such as strength, water retention and adhesion of mortar to meet the standards.
