[0002] Lime and limestone are widely used as raw materials for building materials and industries. Limestone can be directly processed into stones and burned into quicklime. Quicklime becomes slaked lime after absorbing moisture or adding water. Slaked lime is prepared into lime slurry, lime paste, etc. and used as coating materials and brick and tile adhesives. Powder raw materials of limestone need to use conveying devices in the production and processing process;

[0003] In the prior art, a limestone powder conveying device proposed in the utility model patent with the publication number of CN 213943827 U is provided with a primary filter screen and a secondary filter screen at the feed inlet, so that larger particle impurities are removed when limestone powder enters the conveying device, preventing damage to the pipeline. At the same time, a diversion fan and a heating pipe are provided to accelerate the volatilization of moisture in the raw materials and improve the utilization rate of the raw materials;

[0004] However, it does not have the ability to process the limestone powder at the upper end of the screen. The screened limestone powder is easy to block the screen, and it is laborious to clean manually. Shutting down the operation will also affect the conveying efficiency of the device, greatly reducing the practicability and conveying stability of the device, and it is difficult to maintain continuous conveying. At the same time, it conveys limestone powder through the bottom conduit, and the conduit is prone to blockage, and the blocked conduit is not easy to dredge and clean. Therefore, we need to upgrade and transform on the basis of the prior art to overcome the problems and deficiencies it has. Content of the Utility Model

[0025] Preferably, the crushing assembly 5 includes a screening cylinder 51. Insertion rods 52 are provided on the outer side of the screening cylinder 51, and a material guiding plate 53 is connected to the top. A turntable 54 is provided at the center of the screening cylinder 51, and grinding rods 55 are provided on the outer side of the turntable 54. A first motor 56 is connected to the rear end of the turntable 54. The screening cylinder 51 is installed in the insertion slot 21 through the insertion rods 52. The material guiding plate 53 is inclined and correspondingly connected to the lower end of the feed inlet 3. Four groups of grinding rods 55 are provided and are attached to the inner wall of the screening cylinder 51. A motor frame 57 is provided at the bottom of the first motor 56, and the motor frame 57 is fixedly installed on the outer wall of the rear end of the conveying box 2;

[0026] The material inlet 3 is convenient for guiding the raw materials entering through the material guiding plate 53 into the interior of the screening cylinder 51. The screening cylinder 51 facilitates the screening of limestone powder, blocking the limestone powder that does not meet the standards. The first motor 56 facilitates driving the turntable 54 to rotate. The turntable 54 drives the grinding rod 55 to rotate in the screening cylinder 51 and pulverize and grind the limestone powder that has not fallen in the screening cylinder 51, helping the agglomerated limestone powder to be pulverized and conveying it to the lower end.

[0027] Preferably, the feeding assembly 6 includes an extrusion cylinder 61. A threaded sleeve 62 is provided at the upper end of the extrusion cylinder 61. A rear cover 611 is provided on one side of the extrusion cylinder 61. A spiral blade 63 is provided inside the extrusion cylinder 61 and the outer end of the spiral blade 63 is connected to a second motor 64. An extrusion pipe 65 is provided at the lower end of the extrusion cylinder 61. The extrusion cylinder 61 is connected to the lower end of the adapter 4 through the threaded sleeve 62.

[0029] The working principle and working process of the present utility model: When in use, first, the extrusion cylinder 61 can be connected to the lower end of the adapter 4 through the threaded sleeve 62 to make it communicate with the conveying box 2. Limestone powder is added into the conveying box 2 through the material inlet 3. The limestone powder falls into the interior of the screening cylinder 51 through the material inlet 3 and the material guiding plate 53. At this time, the screening cylinder 51 screens the limestone powder. The standard particles directly fall into the adapter 4, and the limestone powder that does not meet the standards will be blocked on the screening cylinder 51. Then, the first motor 56 is started. The first motor 56 drives the turntable 54 to rotate. The turntable 54 drives the grinding rod 55 to rotate in the screening cylinder 51 and pulverize and grind the limestone powder that has not fallen in the screening cylinder 51, helping the agglomerated limestone powder to be pulverized and continuing to convey it to the lower end. There is no need for manual cleaning and the problem that the screening cylinder 51 is prone to blockage is avoided. The screened limestone powder falls into the extrusion cylinder 61. The second motor 64 at the lower end is started. The second motor 64 drives the spiral blade 63 to rotate. The spiral blade 63 can push the raw materials in the extrusion cylinder 61 to move and be conveyed out through the extrusion pipe 65, effectively preventing blockage of the pipeline during the discharging process and improving the conveying efficiency.
