Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to tunnel-type buckwheat rice drying equipment. Background Art

[0002] Tunnel drying equipment is a commonly used grain processing equipment, and is widely used in the drying and processing of grain crops such as buckwheat. Buckwheat can be quickly dried through tunnel drying equipment to facilitate its storage. At the same time, tunnel drying equipment can keep batches of buckwheat at an appropriate humidity. The appropriate humidity can maximize the retention of the nutritional content and taste of buckwheat, and reduce the quality loss caused by over-drying.

[0003] However, in the prior art, since buckwheat grains are relatively small, in order to prevent buckwheat from leaking from the surface of the conveyor belt during the drying process, a belt conveyor without holes is used for the loading conveyor. This feeding method prevents the hot air flow from drying from the lower part of the conveyor belt into the lower layer of buckwheat to form an upward circulation, which in turn causes the upper layer of buckwheat to be heated at a higher temperature than the lower layer during the drying process, resulting in uneven drying of the upper and lower layers of buckwheat. It also causes the buckwheat in the upper layer to have too low a humidity and the buckwheat in the lower layer to have too high a humidity, thereby affecting the drying quality of the buckwheat. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that, because buckwheat grains are small, in order to prevent buckwheat from leaking from the surface of the conveyor belt during the drying process, a belt conveyor without holes is used for the loading conveyor. Such a feeding method will result in the hot air flow from the lower part of the conveyor belt being unable to enter the lower layer of buckwheat to form an upward circulation, which will cause the upper layer of buckwheat to be heated higher than the lower layer during the drying process, resulting in uneven drying of the upper and lower layers of buckwheat, and also causing the upper layer of buckwheat to have too low a humidity and the lower layer of buckwheat to have too high a humidity, thereby affecting the drying quality of buckwheat. A tunnel-type buckwheat drying device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tunnel-type buckwheat rice drying equipment, comprising a fixed frame, a drying box is installed on the upper part of the fixed frame, an exhaust mechanism is installed on the upper part of the drying box, and the fixed frame is fixedly connected to a fixed plate, the fixed plate is located inside the drying box, a plurality of electric heating mechanisms are installed on the upper part of the fixed plate, and the plurality of electric heating mechanisms are evenly distributed on the upper part of the fixed plate, a conveyor body is installed on the upper part of the fixed frame, and a flipping mechanism is provided above the conveyor body, the flipping mechanism includes a connecting shaft, a connecting frame and a flipping plate, the connecting shaft is rotatably connected to the fixed plate, a driven wheel is fixedly connected to the surface of the connecting shaft, the driven wheel is in contact with the upper part of the conveyor body, the connecting frame is fixedly connected to the connecting shaft, and a telescopic rod is fixedly connected to the inside of the connecting frame, one end of the telescopic rod is fixedly connected to the flipping plate, the flipping plate is slidably connected to the connecting frame, and a spring is provided on the surface of the telescopic rod, one end of the spring is fixedly connected to the connecting frame, and the other end of the spring is fixedly connected to the flipping plate.

[0006] Preferably, the exhaust mechanism consists of a mounting shell and an exhaust fan, the exhaust fan is located inside the mounting shell, and the mounting shell is fixedly connected to the top of the drying box.

[0007] Preferably, the electric heating mechanism consists of a bracket and an electric heating tube, the electric heating tube is installed on the surface of the bracket, and the bracket is fixed on the upper part of the fixed plate.

[0008] Preferably, a No. 1 limiting rod is fixedly connected to the interior of the connecting frame, a limiting hole is provided on the surface of the flip plate, and one end of the No. 1 limiting rod is located inside the limiting hole and is slidably connected to the flip plate.

[0009] Preferably, a scraping mechanism is provided above the conveyor body, and the scraping mechanism is located on the side of the flipping mechanism. The scraping mechanism includes a connecting plate, which is fixedly connected to the upper part of the fixed plate, and an electric push rod is fixedly connected to the bottom of the connecting plate, and a scraper is fixedly connected to the bottom of the electric push rod.

[0010] Preferably, the upper portion of the scraper is fixedly connected to a limiting sleeve, the bottom portion of the connecting plate is fixedly connected to a second limiting rod, and the second limiting rod is plugged into the limiting sleeve.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, when the conveyor body is feeding, its conveyor belt assembly rotates, and the movement of the conveyor belt drives the driven wheel to rotate, and then the driven wheel drives the connecting shaft and the connecting frame and the flip plate fixed on the surface to rotate. The flip plate contacts the surface of the conveyor belt during the rotation process, and flips the buckwheat rice on the lower layer to the upper part during the rotation process, so that the buckwheat rice on the upper part of the conveyor body is evenly dried.

[0013] 2. In the utility model, when the flip plate reaches the lower part of the connecting shaft during its rotation, it will be squeezed with the conveyor belt surface of the conveyor body, and the flip plate will slide toward the inside of the connecting frame. At this time, the spring and the telescopic rod will produce compression deformation. The reaction force of the spring and the telescopic rod makes the flip plate fit tightly with the conveyor belt surface, and then all the buckwheat rice in the lower layer can be flipped upwards. The No. 1 limit rod is plugged into the limit hole on the surface of the flip plate for limit limiting, thereby improving the stability of the flip plate during movement.

[0014] 3. In the utility model, after the turning mechanism turns the buckwheat rice layer, the buckwheat rice continues to move forward under the conveying action of the conveyor body. At this time, the scraper will scrape the buckwheat rice flat, so that its thickness on the upper part of the conveyor body remains uniform, avoiding inconsistent thickness of buckwheat rice due to the turning of the turning mechanism, thereby improving the uniformity of buckwheat rice drying. According to the different thicknesses of the dried buckwheat rice, the gap distance between the scraper and the top of the conveyor body is adjusted by the telescopic electric push rod, which is convenient for scraping and flattening buckwheat rice of different drying thicknesses. In the process of the electric push rod adjusting the height of the scraper, the limit sleeve will slide along the No. 2 limit rod, thereby limiting the movement of the scraper, thereby improving the stability of the scraper during movement and operation.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

The exhaust mechanism 4 consists of a mounting shell and an exhaust fan, the exhaust fan is located inside the mounting shell, the mounting shell is fixedly connected to the top of the drying box 3, the electric heating mechanism 6 consists of a bracket and an electric heating pipe, the electric heating pipe is mounted on the surface of the bracket, and the bracket is fixed to the upper part of the fixed plate 5. A number 1 limiting rod 77 is fixedly connected to the inside of the connecting frame 73, and a limiting hole is provided on the surface of the flip plate 74. One end of the number 1 limiting rod 77 is located inside the limiting hole and is slidably connected to the flip plate 74.

[0025] The following is a detailed description of the specific configuration and function of this embodiment. Buckwheat enters from the feeding end of the conveyor body 2. At the same time, the electric heating mechanism 6 and the exhaust mechanism 4 are turned on to heat, dry and ventilate the buckwheat, so that it is quickly dehydrated and dried. When the conveyor body 2 is feeding, its conveyor belt assembly rotates. Under the action of the movement of the conveyor belt, the driven wheel 72 is driven to rotate. The driven wheel 72 then drives the connecting shaft 71 and its surface-fixed connecting frame 73 and the flip plate 74 to rotate. The flip plate 74 contacts the surface of the conveyor belt during the rotation process and flips the buckwheat on the lower layer to the upper part during the rotation process, so that the buckwheat on the upper part of the conveyor body 2 is evenly dried.

[0026] When the flip plate 74 reaches the lower part of the connecting shaft 71 during its rotation, it will be squeezed against the conveyor belt surface of the conveyor body 2, and the flip plate 74 will slide toward the inside of the connecting frame 73. At this time, the spring 76 and the telescopic rod 75 will produce compression deformation. The reaction force of the spring 76 and the telescopic rod 75 makes the flip plate 74 fit tightly against the conveyor belt surface, and then all the buckwheat rice in the lower layer can be flipped upwards. The No. 1 limit rod 77 is plugged into the limit hole on the surface of the flip plate 74 for limit limiting, thereby improving the stability of the flip plate 74 during movement.

[0027] Example 2: Figures 1-6 As shown, a scraping mechanism 8 is provided above the conveyor body 2, and the scraping mechanism 8 is located on the side of the flipping mechanism 7. The scraping mechanism 8 includes a connecting plate 81, which is fixedly connected to the upper part of the fixed plate 5, and an electric push rod 82 is fixedly connected to the bottom of the connecting plate 81, and a scraper 83 is fixedly connected to the bottom of the electric push rod 82. The upper part of the scraper 83 is fixedly connected to a limiting sleeve 84, and a No. 2 limiting rod 85 is fixedly connected to the bottom of the connecting plate 81, and the No. 2 limiting rod 85 is plugged into the limiting sleeve 84.

[0028] The effect achieved by the entire embodiment is that after the turning mechanism 7 turns the buckwheat rice layer, the buckwheat rice continues to move forward under the conveying action of the conveyor main body 2. At this time, the scraper 83 will scrape the buckwheat rice flat, so that its thickness on the upper part of the conveyor main body 2 remains uniform, avoiding inconsistent buckwheat rice thickness due to the turning of the turning mechanism 7, thereby improving the uniformity of buckwheat rice drying. According to the different thicknesses of the dried buckwheat rice, the gap distance between the scraper 83 and the top of the conveyor main body 2 is adjusted by the telescopic electric push rod 82, so as to facilitate the scraping and flattening of buckwheat rice of different dried thicknesses. In the process of the electric push rod 82 adjusting the height of the scraper 83, the limiting sleeve 84 will slide along the second limiting rod 85, thereby limiting the movement of the scraper 83, and improving the stability of the scraper 83 during movement and operation.

[0029] The method of use and working principle of this device are as follows: Buckwheat enters from the feeding end of the conveyor body 2, and the electric heating mechanism 6 and the exhaust mechanism 4 are turned on at the same time to heat, dry and ventilate the buckwheat, so that it is quickly dehydrated and dried. When the conveyor body 2 is feeding, its conveyor belt assembly rotates, and the movement of the conveyor belt drives the driven wheel 72 to rotate, and then the driven wheel 72 drives the connecting shaft 71 and the connecting frame 73 and the flip plate 74 fixed on the surface to rotate. The flip plate 74 contacts the surface of the conveyor belt during the rotation process and flips the buckwheat on the lower layer to the upper part during the rotation process.

[0030] After the turning mechanism 7 turns the buckwheat layer, the buckwheat continues to move forward under the conveying action of the conveyor body 2. At this time, the scraper 83 will scrape the buckwheat flat so that its thickness on the upper part of the conveyor body 2 remains uniform, avoiding inconsistent buckwheat thickness due to the turning of the turning mechanism 7.
