Description

Technical Field

[0001] The utility model relates to the technical field of cooked grain cooling machines, in particular to a punching chain plate used for cooked grain cooling machines. Background Art

[0002] The cooked grain cooler is a device specially used to cool the grain residue materials after cooking. It is designed to improve cooling efficiency, ensure material quality, and adapt to the needs of modern large-scale production. The working principle of the cooked grain cooler is mainly based on the synergy of the mesh belt conveyor system and the blower system. The cooked grain residue materials enter the mesh belt conveyor system through the feed port and are affected by the cold air from the blower system during the conveying process, thereby achieving rapid cooling. At the same time, auxiliary equipment such as the stirring device inside the equipment can ensure that the material is loose and does not clump during the cooling process, further improving the cooling effect.

[0003] Among them, the perforated chain plate plays a vital role in the cooked grain cooling machine. The use of the perforated chain plate in the cooked grain cooling machine is mainly reflected in enhancing ventilation effect, improving cooling uniformity, improving equipment durability, facilitating cleaning and maintenance, and adapting to various production needs.

[0004] In the existing perforated chain plates, the fastening method between the drive shaft and the chain plate mainly adopts bolts and nuts. This fastening method has the advantages of simple structure, easy operation and maintenance. However, during operation, it is subjected to external forces such as vibration and impact for a long time, causing the threaded connection between the bolts and nuts to gradually loosen, resulting in an unstable connection between the drive shaft and the chain plate, affecting the stability of equipment operation.

[0005] Therefore, we have made improvements to this and proposed a punching chain plate for a cooked grain cooling machine. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the utility model provides a punching chain plate for a cooked grain cooling machine.

[0007] The technical solutions provided by this utility model are as follows:

[0008] The transmission gear is connected with the transmission gear of the first end through the guide rail, and the guide rail is connected with the transmission gear of the second end through the guide rail.

[0009] Furthermore, the control member includes a connecting rod, one end of which passes through the connecting block and is fixedly connected to the fixed block, and the other end of the connecting rod passes through the first clamping block and is fixedly connected to the control plate, and the connecting rod is rotatably connected to the first clamping block and the connecting block respectively.

[0010] Furthermore, the other end of the transmission shaft is fixedly connected with a second clamping block, and the second clamping block is arranged in contact with the outer link plate.

[0011] Furthermore, both ends of the outer surface of the transmission shaft are slidably connected to two outer link plates, both ends of the outer surface of the transmission shaft are slidably connected to two inner link plates, and both ends of the outer surface of the transmission shaft are slidably connected to rollers.

[0012] Furthermore, the two inner link plates are respectively located on the inner sides of the two outer link plates and are fitted thereto, the rollers are respectively located on the inner sides of the two inner link plates and are fitted thereto, and one side surface of the inner link plates is respectively fitted thereto with the first snap ring and the second snap ring.

[0013] Furthermore, two sprockets are meshedly connected between the outer link plate and the inner link plate, and the inner surfaces of the two sprockets are fixedly connected to a rotating shaft, and one end of one of the rotating shafts is fixedly connected to a motor.

[0014] The beneficial effects of the utility model are:

[0015] The utility model slides the fixed block into the interior of the rotating groove through the sliding groove, and then rotates the control plate 90 degrees, so that the two ends of the fixed block are rotated to the rear side of the fixed groove, and the control plate is released. The connecting block drives the two ends of the fixed block to be clamped into the interior of the fixed groove under the elastic force of the spring, so that the first clamping block is tightly fitted with the outer chain plate on the front side, and at the same time, the second clamping block fixedly connected to the rear side of the transmission shaft is tightly fitted with the outer chain plate on the rear side, thereby achieving fixation between the first chain plate and the second chain plate, greatly enhancing the stability between the transmission shaft and the first chain plate and the second chain plate, and improving the stability of the transmission equipment operation.

[0036] The working principle of this utility model:

[0037] 1) Installation and disassembly between the first chain plate 1 and the second chain plate 11:

[0038] When installation is required, align the first snap ring 2, the second snap ring 21, the outer link plate 3, the inner link plate 31 and the roller 32, and pass the transmission shaft 22 from back to front through the outer link plate 3, the inner link plate 31, the roller 32, the first snap ring 2 and the second snap ring 21, so that the second clamping block 57 fixed to the rear end of the transmission shaft 22 fits tightly with the outer link plate 3 on the rear side. At this time, the front end of the transmission shaft 22 is flush with the outer link plate 3 on the front side, and then insert the fixing block 53 into the inside of the slide groove 5, so that the first clamping block 56 fits tightly with the outer link plate 3, and then press the control plate 61 backward to drive the connecting rod 6, the fixing block 53 and the connecting block 54 to slide synchronously and stretch the spring 55 to make the fixing block 53 slide to the rotating groove 51, then rotate the control plate 61 90°, driving the connecting rod 6 and the fixed block 53 to rotate synchronously, so that the two ends of the fixed block 53 rotate to the rear side of the fixed groove 52, loosen the control plate 61, and the connecting block 54 drives the fixed block 53, the connecting rod 6 and the control plate 61 to slide forward under the elastic force of the spring 55, so that the two ends of the fixed block 53 slide into the inside of the two fixed grooves 52.
