Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to a material blocking prevention device for a dryer outlet. Background Art

[0002] China is a big agricultural country, especially Shandong, Henan and Northeast China are the main grain producing areas such as corn. With the development of animal husbandry and the increase in demand for feed, the planting area of ​​corn has gradually expanded and the output has increased year by year. The moisture content of corn at harvest is generally 25%-35%. If there is no good corn drying equipment, it will cause a lot of losses due to excessive moisture and mold.

[0003] Therefore, users have an increasingly urgent demand for corn dryers. The development of corn dryers with high moisture content, good drying uniformity and excellent quality is of great significance to the development of the corn industry. At present, there are some bin-type and drum-type corn dryers on the market. These devices use mechanical equipment to reduce the moisture content of corn kernels to a safe packaging and storage range in order to achieve long-term preservation. This is of great significance to reducing post-harvest losses of corn and ensuring a bumper harvest of corn. However, in the process of drying corn, some large-capacity dryers use auger for conveying when discharging. When the amount of material discharged is too large under the action of gravity, the corn will be blocked at the discharge port and the auger, causing difficulty in discharging. The existing solution is to clear the blocked corn by knocking and vibrating, which is difficult to operate, resulting in discontinuous production and affecting production. Utility Model Content

[0004] In order to solve the above problems, the embodiment of the utility model provides a device for preventing material blocking at the outlet of a dryer, which solves the problem of corn blocking at the outlet of the dryer mentioned in the background technology and has a strong use effect.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a device for preventing material blocking at the outlet of a dryer, comprising a material receiving part arranged at the material outlet of the dryer, the material receiving part is arranged along the length direction of the material outlet of the dryer, the material receiving part comprises an outer shell, and two oppositely arranged material outlet rollers are arranged inside the outer shell, and the material outlet rollers are connected to a driving motor.

[0006] Furthermore, the discharge roller is arranged along the length direction of the discharge port of the dryer, and a concave portion for increasing friction is arranged on the side of the discharge roller, and a plurality of the concave portions are arranged along the side of the discharge roller.

[0007] Furthermore, a plurality of connection holes are arranged on the side surface of the discharge roller, and a shifting post is detachably arranged inside the connection hole.

[0008] Furthermore, the two discharging rollers are horizontally arranged on the same plane, and the distance between the two discharging rollers is adjustable.

[0009] Furthermore, a feeding auger is arranged below the discharging roller.

[0010] Furthermore, a brush for scraping material is provided below the discharging roller.

[0011] The beneficial effects of the embodiments of the utility model are as follows: the discharging rollers are installed at the discharging port of the dryer, and are in contact with the materials inside the dryer during the discharging process, thus having a certain gathering effect, and preventing the materials from getting stuck at the discharging port by rotating.

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] See also Figures 1 to 3 This embodiment provides a device for preventing material blocking at the outlet of a dryer, which is intended to solve the problem of material blocking at the outlet of the dryer, thereby improving drying efficiency and reducing equipment failures.

[0018] First of all, the dryer outlet anti-blocking device of this embodiment mainly includes a material receiving part, which is arranged at the discharge port of the dryer, and its length direction is consistent with the length direction of the discharge port of the dryer. Such a design can ensure that the material can smoothly enter the material receiving part after leaving the dryer, providing a basis for subsequent anti-blocking work.

[0019] The material receiving part includes a shell 2 installed at the lower part of the dryer. The shell 2 is bolted to the shell of the dryer and is detachable for easy adjustment and maintenance. Two oppositely arranged discharge rollers 201 are installed inside the shell 2. The two discharge rollers 201 are the main power transmission components of the device and are installed along the length direction of the discharge port. They are driven by a drive motor to achieve rotation. When the discharge rollers 201 rotate, they can push the material to move downward to prevent the material from piling up and clogging at the outlet.

[0020] It is worth mentioning that the two discharge rollers 201 in this embodiment are horizontally arranged on the same plane, and the distance between them can be adjusted by a waist-shaped hole opened on the outer shell 2. Such a design enables the device to adapt to materials of different particle sizes and can also adjust the discharge rate. By adjusting the distance between the discharge rollers 201, the distance between the two discharge rollers 201 is changed. When the distance is increased, the falling speed of the material can be accelerated, and when the distance is reduced, the discharge speed can be slowed down. Especially in the bin type dryer, the discharge port is rectangular, and the rotation speed and spacing of the discharge rollers 201 can be adjusted according to the needs of material discharge, which can ensure that no blockage occurs at the discharge port during the material discharge process, thereby ensuring the use effect and enhancing the control ability.

[0021] In order to increase the friction between the discharge roller 201 and the material and improve the pushing effect, we set a plurality of recessed portions 203 on the side of the discharge roller 201. These recessed portions 203 are distributed along the side of the discharge roller 201, so that the discharge roller 201 can better push the material forward when rotating.

[0022] In addition, in order to further improve the adaptability and flexibility of the device, we also set a plurality of connecting holes 204 on the side of the discharge roller 201. These connecting holes 204 are detachably provided with shifting posts, wherein the shifting posts are bolt posts protruding from the top, and the shifting posts are screwed to the connecting holes 204, and the tops of the shifting posts protrude from the discharge roller 2015-8mm. For some dryers with a higher material discharge rate, by adjusting the number and position of the shifting posts, we can fine-tune the pushing effect of the discharge roller 201 according to the characteristics of the material and the drying requirements, so as to achieve the best anti-blocking effect.

[0023] In order to further improve the material conveying efficiency, a feeding auger 1 is arranged below the discharge roller 201 to make the conveying distance longer. The feeding auger 1 can convey the material from under the discharge roller 201 and control the rotation speed of the discharge roller 201 to prevent the material from being blocked inside the auger 1 and to avoid the accumulation of material at the outlet, thereby effectively preventing the occurrence of blockage.

[0024] Finally, in order to keep the discharge roller 201 clean and in good working condition, we also set a brush 202 for scraping material under the discharge roller 201. The brush 202 can scrape off the residual material on the discharge roller 201 to prevent excessive accumulation of material on the discharge roller 201, thereby ensuring the stable operation of the device.

[0025] To sum up, the dryer outlet anti-blocking device of this embodiment adopts a double discharge roller design to achieve efficient transportation and anti-blocking of materials at the dryer outlet. The device is not only simple in structure and easy to operate, but also has strong adaptability and can be applied to different materials and drying requirements. It can meet the discharge of materials such as wheat and corn after drying. In actual applications, the device can significantly improve the drying efficiency, reduce the equipment failure rate, and bring better results to the material drying process.
