Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grain processing equipment, in particular to a drum type grain drying equipment. Background Art
[0002] After harvest, grains have a high moisture content, especially those that are harvested before the weather turns bad. They are not fully mature and have a higher moisture content. In order to meet commodity standards, certain drying operations are required to reduce the moisture content in the grains. Grain drying is done by hot air, which heats the air and then blows on the grains. Heating speeds up the evaporation of water, while air circulation can take away the moisture. The dried grains can be stored for a long time.
[0003] In the existing drying equipment, the grain layer through which the hot air passes is very thick. The grain on the surface can be dried, but the drying effect of the deeper grain is very poor. It is necessary to cooperate with the turning device to continuously turn the grain to meet the drying requirements of each position. Therefore, the utility model combines the characteristics of the existing drying equipment to prepare a circulating drying device, add a drum structure, and turn the material through the rotation of the drum, so as to achieve the purpose of uniform drying of the grain. Utility Model Content
[0004] The utility model aims to provide a drum type grain drying equipment, and combines the characteristics of existing drying equipment to prepare a circulating drying device, add a drum structure, and turn the material through the rotation of the drum, so as to achieve the purpose of evenly drying the grains.
[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
[0006] A drum type grain drying device comprises a drum, a sleeve is sleeved on the outside of the drum, the drum and the sleeve are coaxially arranged, one side of the drum is an open side, and the other side is connected to a feed pipe, and the sleeve is fixedly installed;
[0007] It includes a driving device for driving the roller to rotate on the axis of the sleeve. The roller is provided with spiral blades. A hot air pipe is connected to one side of the sleeve corresponding to the feed pipe. An air hole is opened at the position of the roller corresponding to the hot air pipe connection.
[0008] Furthermore, the driving device includes a motor, and the roller corresponds to a sleeve for receiving the feeding pipe, the sleeve is fixed to the roller, and the sleeve is sleeved with a gear, and the motor drives the gear to connect and rotate the entire roller.
[0009] Furthermore, a plurality of annular wheel grooves are fixedly installed on the outer side wall of the drum, and rollers are installed in the wheel grooves, which are supported on the inner side wall of the sleeve and rotated through the rollers.
[0010] Furthermore, the feed pipe has an arc section, and the arc section corresponding to the feed pipe turns upward and is connected to the funnel.

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] like Figure 1-2As shown: A drum-type grain drying device includes a drum 1, and a sleeve 2 is sleeved outside the drum 1. Both the drum and the sleeve are cylindrical shell structures. The drum 1 and the sleeve 2 are coaxially arranged. One side of the drum 1 is an open side, and the other side is connected to a feeding pipe 3. The sleeve 2 is fixedly installed. The side of the drum corresponding to the feeding pipe is a sealed side, and a feeding port is arranged in the center for the feeding pipe to be inserted. The feeding pipe is used to transport grains into the drum.
[0020] It includes a driving device for driving the drum 1 to rotate around the axis inside the sleeve 2. There is a spiral blade 11 inside the drum 1. One side of the sleeve 2 corresponding to the feeding pipe 3 is connected to a hot air pipe 21, and a gas hole 10 is opened at the position where the drum 1 corresponds to the connection of the hot air pipe 21. The outer side of the spiral blade is fixed to the inner side wall of the drum. The drum rotates around the axis under the action of the driving device, which is used to move the grains entering from the feeding pipe at the end side to the other open side. During the driving process of the grains by the spiral blade, the grains also keep tumbling. The hot air flow entering from the hot air pipe enters the drum through the gas hole and flows from one side of the drum where the feeding pipe is located to the other open side, heating and drying the tumbling grains, and at the same time, it can take away the water vapor. The device is a production line drying device, which can be used without stopping. The rotation of the drum is relatively slow, so there can be sufficient drying time.
[0021] As Figure 2-3 shown: The driving device includes a motor. The drum 1 correspondingly has a sleeve 12 sleeved with the feeding pipe 3. The sleeve 12 is fixed to the drum 1. A gear 13 is sleeved on the sleeve 12, and the whole drum 1 is driven to rotate by driving the gear 13 through the motor. The position of the motor is not shown in the figure. The motor drives the whole drum to rotate through the driving cooperation of the gear chain, which is stable and reliable.
[0022] A plurality of annular wheel grooves 4 are fixedly installed on the outer side wall of the drum 1. Roller wheels 41 are installed in the wheel grooves 4 and are supported and rotated on the inner side wall of the sleeve 2. The roller wheel is a cylindrical roller body structure, and there is a roller shaft at the central median position. The wheel groove is annular, sleeved on the drum, and the whole is annular, and the cross-section is U-shaped. The wheel grooves are arranged along the length direction of the drum. The gas hole is located between the first wheel grooves corresponding to the drum. The wheel grooves just form a seal to prevent the air flow from overflowing from the interlayer between the drum and the sleeve, and promote the air flow to enter the inside of the drum.
[0023] The feeding pipe 3 has an arc section, and the arc section corresponding to the feeding pipe 3 turns upward and is connected to a funnel 31. After adding grains, the grains enter the drum along the feeding pipe. A feeding belt is installed at the position of the funnel to feed the grains orderly and evenly. The funnel can prevent the grains from spilling.
[0024] As Figure 1 shown: The hot air pipe 21 is a corrugated pipe. The sleeve 2 has an interface sleeve for the pipe orifice of the hot air pipe 21 to be sleeved and connected. The sleeve 2 is supported and elevated by a support frame 22. It is convenient for the drum to discharge materials for receiving. At the same time, the hot air pipe can be disassembled and installed, which is convenient for maintenance.
[0025] The sleeve 2 has an inner buckle type annular sealing ring 23 on one side corresponding to the feed pipe 3, which is used to seal the sleeve 2 and the corresponding side sandwich of the end side of the drum 1. The annular sealing ring is fixed integrally with the side of the sleeve, and is used to seal the sandwich formed by the sleeve and the end side of the drum to prevent hot air from overflowing.
[0026] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
