Description

Technical Field

[0001] This utility model relates to the field of straw processing technology, and in particular to an integrated straw drying and dust removal device. Background Technology

[0002] Straw is the general term for the stems, leaves, and ears of crops remaining after harvest. It is a common byproduct of agricultural production, mainly derived from various crops such as wheat, rice, corn, cotton, and soybeans. Straw recycling and reuse is a key measure to overcome the agricultural waste problem and promote green development, possessing multiple irreplaceable advantages. It can transform straw that would otherwise be burned or discarded into usable resources, avoiding the waste of valuable components such as cellulose and lignin, and filling supply gaps in areas such as feed, energy, and industrial raw materials.

[0003] In the initial stage of straw recycling, due to the field working environment, the surface of straw is generally covered with a large amount of soil particles, weed debris, and other impurities, while the interior retains a high proportion of free and bound water due to the physiological characteristics of the crop at harvest and the field humidity conditions. However, most straw processing facilities currently still adopt a step-by-step operation mode of "cleaning first, then drying": first, surface impurities are removed by screening and air separation equipment, and then the cleaned straw is transferred to a drying yard or drying equipment for dehydration. This mode has obvious shortcomings. On the one hand, secondary pollution is easily caused during the transportation process, and equipment switching and material handling consume a lot of time and manpower; on the other hand, the step-by-step operation makes it difficult to achieve process connection and parameter coordination, resulting in low overall processing efficiency, which cannot meet the needs of large-scale straw recycling and utilization, and also restricts the large-scale development of the straw resource utilization industry to a certain extent.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an integrated straw drying and dust removal device, including a top plate 1 and a bottom plate 2. Several axial flow fans 4 are fixedly connected to the surface of the top plate 1. A dust removal screen plate 5 is provided above the top surface of the bottom plate 2. Vibration plates 11 are connected to the bottom plate 2 at the four corners of the dust removal screen plate 5. A connecting column 10 is fixedly connected to one end of the dust removal screen plate 5. A vibration motor 3 is provided at the other end of the bottom plate 2. A deflection rod 7 is fixedly connected to the output end of the vibration motor 3. A transmission rod 6 is movably connected between the deflection rod 7 and the connecting column 10.

[0023] The specific setup and function of this embodiment are described below. When straw processing is required, some straw is laid flat on the upper surface of the dust removal screen plate 5. After the roots of the straw are fixed by the pressure seat 8, the vibration motor 3 and the axial flow fan 4 are started simultaneously to complete the integrated operation of air drying and dust removal. The vibration motor 3 drives the deflection rod 7 to rotate, causing the deflection rod 7 to drive the transmission rod 6 to deflect. The top end of the transmission rod 6 is connected to the column 10, which rotates accordingly. Because the end of the deflection rod 7 moves in a circular motion, the dust removal screen plate 5 moves accordingly. The screen plate 5 vibrates up and down, and a vibrating plate 11 is installed between the dust removal screen plate 5 and the bottom plate 2. The vibrating plate 11 is made of a strong and tough material, which can realize the vibration effect of the dust removal screen plate 5. The surface of the dust removal screen plate 5 is provided with multiple sets of filter holes, which can effectively shake off the dust. The axial flow fan 4 blows air from top to bottom towards the dust removal screen plate 5. The filter holes on the surface of the dust removal screen plate 5 can allow the air to pass through the straw. The straw is dried under the action of airflow. At the same time, the airflow can blow away the dust attached to the surface of the straw, realizing the integrated function of drying and dust removal.

[0024] Example 2: Figure 1 and Figure 3As shown, the dust removal screen plate 5 has its two sides bent upwards to form baffles. A pressure-regulating seat 8 is movably connected to the other end of the dust removal screen plate 5, and the pressure-regulating seat 8 is used to fix the roots of the straw. Connecting seats 1-9 are fixedly connected to the four corners of the dust removal screen plate 5, and connecting seats 1-9 are movably connected to the vibrating plate 11. Connecting seat 2-12 is fixedly connected to the bottom end of the vibrating plate 11, and connecting seat 2-12 is fixedly connected to the base plate 2.

[0025] The bottom end of the dust collection screen plate 5 is fixedly connected to the ear plate 13, and the end of the connecting column 10 is fixedly connected to the ear plate 13. The bottom plate 2 has a stepped structure with a higher middle and lower sides, and containers are set on both sides of the bottom plate 2 to collect dust. Columns are installed at the four corners of the top plate 1, and shock-absorbing pads are set at the bottom of the columns.

[0026] The overall effect of this embodiment is that, in order to ensure that the airflow on the surface of the axial fan 4 has a strong stability, a shock-absorbing pad is set at the bottom of the column below the top plate 1 to alleviate the fluctuation of the top plate 1. A freely rotatable pressure seat 8 is set at the end of the dust removal screen plate 5. By deflecting the pressure seat 8 toward the upper surface of the dust removal screen plate 5, the pressure seat 8 can press the end of the straw tightly. Since the roots of the straw do not have ear seedlings, they have less dust and less moisture adhering to the surface. Therefore, the pressure seat 8 will not affect the drying and dust removal effect of the straw itself.

[0027] The operating method and working principle of this device are as follows: During operation, the straw is laid flat on the dust removal screen plate 5, and the roots of the straw are fixed with the pressure seat 8. The vibration motor 3 and the axial flow fan 4 are started: the vibration motor 3 drives the deflection rod 7 to rotate, and the transmission rod 6 connects the deflection rod 7 to the connecting column 10. The connecting column 10 is connected to the ear plate 13 of the dust removal screen plate 5. The transmission rod 6 causes the connecting column 10 to move, which causes the dust removal screen plate 5 to drive the vibration plate 11 to vibrate up and down through the connecting seat 1 9. The bottom end of the vibration plate 11 is connected to the bottom plate 2 through the connecting seat 2 12. The dust is shaken off by the filter holes on the surface of the dust removal screen plate 5 and falls into the containers on both sides of the bottom plate 2. The bottom plate 2 has a stepped structure with a high middle and low sides. At the same time, the axial flow fan 4 is installed on the top plate 1 and blows air from top to bottom towards the dust removal screen plate 5. The airflow passes through the filter holes and passes through the straw, blowing away the surface dust while drying the straw. The bottom ends of the columns at the four corners of the top plate 1 are equipped with shock-absorbing pads to reduce the fluctuations and realize the integration of drying and dust removal.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
