[0014] A conveying method of a conveying device for producing dry mortar, comprising the following steps:

[0015] S1: Screening of mortar raw materials. The output shaft rotates to drive the spiral blades on the feeding shaft to rotate. The spiral blades rotate to transport the dry mortar raw materials at the bottom of the feed hopper to the inside of the screening cylinder. At this time, the mortar particles that meet the specifications in the dry mortar are screened out of the screening cylinder through the screening holes. At this time, the larger mortar particles and gravel in the mortar will continue to remain in the screening cylinder and finally be screened out through the screening port.

[0016] S2: Crushing the agglomerated raw materials, the feed shaft rotates to drive the sliding block inside the sliding groove to rotate, the sliding block rotates to drive the linkage rod to rotate, the linkage rod rotates to drive the rolling column to rotate, because the agglomerated particles inside the screening cylinder are always at the bottom of the inner wall of the screening cylinder and move upward, at this time the rolling column is squeezed with the inner wall of the screening cylinder;

[0017] S3: Auxiliary crushing. When the rolling column is squeezed by hard blocks such as stones, the rolling column drives the sliding block 1 at one end of the linkage rod to squeeze the squeezing spring. At this time, the squeezing column pushes the sliding piston to slide along the inner wall of the sliding sleeve. At this time, the squeezing column gives a reaction force to the sliding block 2. The sliding block 2 slides along the sliding groove under the reaction force. At this time, the sliding block 2 drives the sliding piston on the squeezing column in the adjacent auxiliary screening mechanism to squeeze the sliding block 1. At this time, the squeezing force between the rolling column in the adjacent auxiliary screening mechanism and the inner wall of the screening cylinder is greater;

[0018] S4: Conveying dry mortar, the output shaft rotates to drive the rotating column at one end of the transmission belt to rotate, the rotation of the rotating column drives the rotating groove ring on the gear to rotate, the rotation of the rotating groove ring drives the feeding spiral blade inside the conveying chamber to rotate, the feeding spiral blade rotates to convey the qualified dry mortar inside the conveying chamber to the discharge port, so that the dry mortar can be conveyed to a predetermined height.

[0019] The present invention has the following beneficial effects:

[0020] (1) According to the present invention, when the conveying equipment for producing dry mortar is used, the dry mortar raw materials are first placed in the feed hopper, and then the driving motor is started. The output end of the driving motor rotates to drive the output shaft to rotate, and the output shaft rotates to drive the sieving spiral blades on the feeding shaft to rotate. The sieving spiral blades rotate to convey the dry mortar raw materials at the bottom of the feed hopper to the inside of the screening cylinder. At this time, the mortar particles that meet the specifications in the dry mortar are sifted out of the screening cylinder through the sifting holes. At this time, the mortar particles with larger particles in the mortar and the gravel in the mortar will continue to remain in the screening cylinder and finally be sifted out through the sifting opening. Since the edge of the sifting spiral blade contacts the inner wall of the screening cylinder, the sifting spiral blade continuously scratches the sifting holes on the sifting spiral blade during rotation. Such a setting is conducive to improving the screening efficiency of the sifting holes and avoiding the sifting holes from being blocked by agglomerates. By setting the conveying and screening device, it is conducive to sifting out the agglomerated particles in the dry mortar during the conveying process, thereby improving the production quality of the dry mortar.

[0021] (2) The present invention provides an auxiliary screening mechanism. When the output shaft rotates, it drives the feed shaft to rotate. The feed shaft drives the sliding block inside the sliding groove to rotate. The sliding block drives the linkage rod to rotate. The linkage rod drives the rolling column to rotate. Since the agglomerated particles inside the screening cylinder are always at the bottom of the inner wall of the screening cylinder and move upward, the rolling column is squeezed against the inner wall of the screening cylinder. When the rolling column is squeezed against the agglomerated dry powder mortar inside the screening cylinder, it is beneficial to crush the agglomerated dry powder mortar. Therefore, the device can make full use of the dry powder mortar raw materials and increase the output of dry powder mortar.

[0022] (3) In the present invention, when the rolling column is squeezed by hard blocks such as stones, the rolling column drives the sliding block 1 at one end of the linkage rod to squeeze the squeezing spring. At this time, the squeezing column pushes the sliding piston to slide along the inner wall of the sliding sleeve. At this time, the squeezing column gives a reaction force to the sliding block 2. The sliding block 2 slides along the sliding groove under the reaction force. At this time, the sliding block 2 drives the sliding piston on the squeezing column in the adjacent auxiliary screening mechanism to squeeze the sliding block 1. At this time, the squeezing force between the rolling column in the adjacent auxiliary screening mechanism and the inner wall of the screening cylinder is greater, so that the crushing effect of the rolling column in the adjacent auxiliary screening mechanism on the agglomerated dry powder mortar is stronger.

[0023] (4) The present invention, by setting an auxiliary transmission mechanism, drives the output end of the motor to rotate and drives the output shaft to rotate, the output shaft rotates and drives the rotating column 1 at the first end of the transmission belt to rotate, the output shaft rotates and drives the rotating column 2 at the second end of the transmission belt to rotate, the rotating column 2 rotates and drives the gear 2 to rotate, the rotating column 1 rotates and drives the rotating groove ring on the gear 1 to rotate, the rotating groove ring rotates and drives the feeding spiral blade inside the conveying chamber to rotate, the feeding spiral blade rotates and conveys the qualified dry powder mortar inside the conveying chamber to the discharge port, so that the dry powder mortar is conveyed to a predetermined height, the inner edge of the feeding spiral blade contacts the lower outer wall of the screening drum, and the feeding spiral blade can scratch the outer wall of the screening drum when it rotates, so that the sieve holes can be further prevented from being blocked.

The function of this component is that when the dry mortar production conveying equipment is used, the dry mortar raw material is first put into the feed hopper 201, and then the drive motor 13 is started. The output end of the drive motor 13 rotates to drive the output shaft 14 to rotate, and the output shaft 14 rotates to drive the screening spiral blade 203 on the feed shaft 202 to rotate, and the screening spiral blade 203 rotates to output the dry mortar raw material at the bottom of the feed hopper 201 The mortar particles that meet the specifications in the dry mortar are screened out of the screening cylinder 12 through the screening holes 204. At this time, the larger mortar particles and the gravel in the mortar will continue to remain in the screening cylinder 12 and are finally screened out through the screening port 205. Since the edge of the screening spiral blade 203 is in contact with the inner wall of the screening cylinder 12, the screening spiral blade 203 continuously scratches the screening holes 204 on the screening spiral blade 203 during rotation. This arrangement is conducive to improving the screening efficiency of the screening holes 204 and avoiding the screening holes 204 from being blocked by agglomerates.

The screening efficiency of 204 is improved to avoid the screening hole 204 being blocked by agglomerates. By setting up the conveying and screening device 2, it is beneficial to screen out the agglomerated particles in the dry-mixed mortar during the conveying process, thereby improving the production quality of the dry-mixed mortar; by setting up the auxiliary screening mechanism 3, when the output shaft 14 rotates, the feeding shaft 202 is driven to rotate, and the feeding shaft 202 rotates to drive the sliding block 1 302 inside the sliding groove 301 to rotate, and the sliding block 1 302 rotates to drive the linkage rod 303 to rotate, and the linkage rod 303 rotates to drive the rolling column 304 to rotate. Since the agglomerated particles located inside the screening cylinder 12 are always at the bottom of the inner wall of the screening cylinder 12 and move upward, the rolling column 304 is squeezed with the inner wall of the screening cylinder 12 at this time. When the rolling column 304 is squeezed with the agglomerated dry-mixed mortar inside the screening cylinder 12, it is beneficial to crush the agglomerated dry-mixed mortar, so that the device can make full use of the dry-mixed mortar raw materials and improve the output of the dry-mixed mortar.

[0052] When the crushing column 304 is squeezed by hard blocks such as stones, the crushing column 304 drives the sliding block 1 302 at one end of the linkage rod 303 to squeeze the squeezing spring 306.

At this time, the squeezing column 308 gives a reaction force to the sliding block 2 309, and the sliding block 2 309 slides along the sliding groove 301 under the reaction force. At this time, the sliding block 2 309 drives the sliding piston 307 on the squeezing column 308 in the adjacent auxiliary screening mechanism 3 to squeeze the sliding block 1 302. At this time, the squeezing force between the crushing column 304 in the adjacent auxiliary screening mechanism 3 and the inner wall of the screening cylinder 12 is greater, so that the crushing effect of the crushing column 304 in the adjacent auxiliary screening mechanism 3 on the agglomerated dry powder mortar is stronger; by setting the auxiliary transmission mechanism 4, the output end of the driving motor 13 rotates to drive the output shaft 14 to rotate The output shaft 14 rotates and drives the rotating column 1 403 at one end of the transmission belt 1 401 to rotate.
