[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The structure of the outdoor batch dryer is as follows: Figure 3The figure shows a main body 1 and an outer shell, which is an outer cover and connected to the main body 1 to protect it. The main body 1 is used for grain drying operations, and includes a stand 11, a bottom grain discharge system 12, a drive unit 13, a drying layer 14, an air mixing chamber 141, a heat source 15, a grain storage section 16, a circulating elevator 17 and a fan 18. The stand 11, the bottom grain discharge system 12, the drive unit 13, the drying layer 14 and the grain storage section 16 are sequentially arranged from bottom to top to form a drying main body. The air mixing chamber 141 and the exhaust chamber 142 are respectively arranged at the front and rear ends of the drying layer 14. The heat source 15 is arranged at the air inlet of the air mixing chamber 141, and the fan 18 is installed in the exhaust chamber 142. The circulating elevator 17 is arranged at the rear of the drying main body and passes through the exhaust chamber 142, so that the drying main body can be arranged closely in parallel to save floor space, and the fan duct 181 connected to the fan 18 is as shown in FIG. Figure 4 In order to facilitate the grain feeding situation inside the grain storage layer 16, a plurality of material level sensors are arranged inside the grain storage layer 16, and the material level sensors can be arranged in four groups, five groups, etc. along the vertical direction of the grain storage layer 16.

[0034] The outer shell part includes a bottom protective shell surrounded by a front outer wall 2, a rear outer wall 3, a left outer wall 4, and a right outer wall 5, and a roof 6 arranged on the upper end of the bottom protective net shell. Figure 5 As shown, the front outer wall 2 and the rear outer wall 3 are respectively arranged at the front and rear ends of the main part 1 and are connected with the air mixing chamber 141 and the grain storage part 16 by holes. The upper outer wall 21 and the lower outer wall 23 of the front outer wall 2 and the rear outer wall 3 are connected and assembled through the downwardly inclined roof 22. At this time, the relative distance between the lower outer wall 23 and the main part 1 is increased, so that a working cavity for workers to enter is formed between them. The above-mentioned roof 22 can be set at the corresponding position of the grain storage part 16, and is made of galvanized corrugated sheet or lighting tile. Then, the front outer wall 2 and the rear outer wall 3 are both provided with an inspection platform 7 above the working cavity, so as to facilitate the inspection and maintenance of the structural components such as the level meter and temperature sensor of the main part 1. Then, its height can correspond to the drying layer 14. In addition to the above-mentioned setting method, the height of the above-mentioned inspection platform 7 can be arranged according to the relative height of the working cavity to meet the needs of the main part 1 arranged at different heights. The front outer wall 2 is provided with a louver structure air intake 24 at the lower outer wall 23, which can prevent rainwater from entering while replenishing air, and the rear outer wall 3 is provided with a connecting channel 31 at the lower outer wall 23, thereby ensuring the passage of the fan duct 181. Figure 2 and Figure 3As shown, the left outer wall 4 and the right outer wall 5 include a fixing bracket 41 and a plurality of galvanized plates 43, and the protective surface in the figure is formed according to the structure of the front outer wall 2 and the rear outer wall 3. During the application process, one end of the fixing bracket 41 is connected to the side wall of the drying body, and the other end forms an auxiliary support end for installing the galvanized plate 43. The auxiliary support end is vertically connected with a plurality of rectangular steel bars 42, and then the galvanized plate 43 is fixed on the bar 42 using self-tapping screws with waterproof washers to complete the unit assembly. According to the technology of the existing dryer, the drying body is composed of several layers of structure, and the unit assembled galvanized plates 43 constituting the left outer wall 4 and the right outer wall 5 can form a side wall protective layer corresponding to the side wall interlayer of the drying body through the fixing bracket 41. In the application process, each layer of the side wall protective layer can be assembled with the interlayer of the main part and hoisted together, thereby reducing the use of hanging baskets and the process of workers binding the side wall panels at high altitude, thereby improving the work progress. The upper outer wall 12 of the above-mentioned front outer wall 2 and rear outer wall 3 can also be assembled using this method. In order to ensure the structural strength, a reinforced cement wall 44 with a certain height matching the width of the main part is provided at the middle of the bottom end of the left outer wall 4. The height can be set according to the actual application requirements. For example, the height of the reinforced cement wall 44 can be set to match the structure of the drying layer 14. In order to ensure the smooth entry and exit of the staff in the working cavity, rolling shutters 45 are provided on both sides of the reinforced cement wall 44, so as to serve as the working entrance and exit to ensure the smooth work of the staff. The roof 6 is a single-slope roof 22 arranged above the drying body, i.e., the grain storage layer 16, and is matched with a diagonal brace, including a single-slope top 61, a front plate wall 62, a rear plate wall 63 and a roof bottom plate 65. The front plate wall 62 and the rear plate wall 63 are galvanized plates and are vertically installed on the roof bottom plate 65. The single-slope top 61 is installed above the front plate wall 62 and the rear plate wall 63 and surrounds the upper cavity, which can be made of galvanized corrugated plates or lighting tiles. The roof bottom plate 65 has an operation opening corresponding to the upper cavity for the working application of the circulating hoist 17, and the front wall 62 and the rear wall 63 are provided with sliding windows 64 for ventilation and lighting. The roof bottom plate 65 is extended to form an inspection platform, thereby meeting the needs of the process layout channel and facilitating personnel walking and inspection. At the same time, the roof bottom plate 65 also forms a corresponding walking channel at the upper cavity.

[0035] In order to ensure the application stability of the equipment, a number of lighting components are arranged in the shell part. The lighting components can adopt a linear light source installed on the roof 6, the maintenance platform 7, etc. in a side wall manner to obtain a larger lighting area.

[0036] When the machine is used in cold regions, the outer shell is made of pre-made double-layer plates and filled with insulation materials with peeling limit materials. The plates can be directly used for assembly at the assembly site without the need to purchase insulation materials separately. Since the insulation materials are filled inside, damage caused by wind and rain is reduced, the drying temperature is guaranteed, and the application flexibility is improved.

[0037] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
