Description

Technical Field

[0001] This utility model relates to the field of grain cooler technology, and in particular to an air outlet structure for a grain cooler and a grain cooler. Background Technology

[0002] Mobile grain coolers are mobile devices specially designed based on a comprehensive analysis of the characteristics of my country's grain storage environment and climate. Through refrigeration, dehumidification, and ventilation technologies, they effectively reduce the temperature of grain piles, control humidity in grain warehouses, prevent grain from overheating, mold, and pests, and ensure grain storage safety. The biggest advantage of this equipment is its ability to handle overheated grain in emergencies, eliminating the need for multiple fixed installations. After treating grain in warehouse A, it can be moved to grain warehouse B for further cooling.

[0003] Mobile grain coolers are moved manually by equipping the unit with wheels. After cooling the grain in a designated area, workers move the equipment to the equipment room for storage. During storage, mobile grain coolers generally face a significant problem: Figure 1 The existing mobile grain chaff machine's air outlet is a direct through-hole in the side wall of the machine's casing. This relatively open design lacks effective protective measures, making it easy for foreign objects to enter when the machine is not in use. This is especially true in complex environments with lots of clutter, such as storage rooms. Dust, paper scraps, and other lightweight items can easily be blown into the outlet by the airflow and adhere to the delicate internal components, affecting normal operation. More seriously, small animals like rats may be present in the storage room. Driven by instinct, they often crawl into the outlet, gnawing on wiring and damaging the internal structure, leading to equipment damage, increased maintenance costs, and even affecting subsequent normal use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air outlet structure for a grain processor, which solves the problem that the open design of the air outlet of a mobile grain cooling unit in the prior art makes it easy for debris to enter and damage the equipment when it is not in use.

[0005] According to an embodiment of the present invention, an air outlet structure for a grain machine includes a mounting plate, one side of which is recessed to form a recessed portion, an annular protrusion is provided through the recessed portion, and a cover plate is provided on the side of the recessed portion away from the annular protrusion, the cover plate being rotatably connected to the mounting plate by a hinge.

[0006] Compared with the prior art, this utility model has the following beneficial effects: By enlarging the air outlet of the grain thresher that was originally connected to the external connecting pipe, and setting an inwardly recessed part at this position through the mounting plate, an annular convex pipe is set in the recessed part, allowing the gas discharged from the output end of the grain thresher to be discharged through the annular convex pipe. When not in use, the cover plate can be rotated to close the cover plate on the recessed part, thereby covering the air outlet of the grain thresher. This prevents debris and rodents from the surrounding environment from entering the grain thresher through the air outlet when the grain thresher is stored in an unused room, effectively protecting the internal components of the grain thresher from damage and extending the service life of the grain thresher.

[0007] Furthermore, the cover plate is also equipped with a locking mechanism, and the inner wall of the recess is provided with a locking groove for the locking tongue of the locking mechanism to be inserted.

[0008] Furthermore, at least one limiting element is provided on the inner wall of the recess.

[0009] Furthermore, each limiting member includes a limiting part and a connecting part, the connecting part being L-shaped, and the limiting part and the connecting part being fixed to the side facing the cover plate.

[0010] Furthermore, the connecting part is connected to the inner wall of the recessed part by screws.

[0011] Furthermore, a protective net is installed inside the annular convex tube.

[0012] Furthermore, the annular convex tube has an anti-slip flange on its circumferential outer wall.

[0013] This utility model also provides a grain machine, including a housing and an air outlet structure of the grain machine. The mounting plate of the air outlet structure is detachably connected to the housing. A blower is provided inside the housing, and the output end of the blower is connected to an annular convex pipe.

[0014] Furthermore, the mounting plate is connected to the housing with screws. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 2 to 4 As shown in the figure, this utility model embodiment proposes an air outlet structure for a grain machine, including a mounting plate 1. One side of the mounting plate 1 is recessed inward to form a recessed part. An annular protrusion 2 is provided through the recessed part. A cover plate 3 is provided on the side of the recessed part away from the annular protrusion 2. The cover plate 3 is rotatably connected to the mounting plate 1 by a hinge 4. Specifically, the annular convex tube 2 is a hollow circular tube structure that connects the two ends of the mounting plate 1. The annular convex tube 2 is located inside the recessed part, and the mounting plate 1 is set on the grain thresher. The mounting plate 1 is fixed to the air outlet of the grain thresher, and the air outlet of the grain thresher discharges gas through the annular convex tube 2. When using the grain thresher, after moving it to the predetermined position, a connecting pipe is connected to the annular convex tube 2 to guide the discharged air to process grain in a specific area. When not in use, the connecting pipe is removed, and the grain thresher is moved to an unused room. At this time, the cover plate 3 is rotated to cover the recessed part, thus blocking the recessed part and preventing debris in the storage space from entering the grain thresher through the annular convex tube 2 and damaging the internal parts of the grain thresher when it is not in use, effectively extending the service life of the grain thresher.

[0023] like Figure 2 and Figure 3 As shown, the cover plate 3 is further provided with a locking mechanism 5, and a locking groove 6 is provided on the inner wall of the recess for the locking tongue of the locking mechanism 5 to be inserted. In this embodiment, the locking mechanism 5 is provided on the free end of the cover plate 3. The locking mechanism 5 can be selected from the prior art. When the grain machine is stored in an unused room, the cover plate 3 and the mounting plate 1 are locked by controlling the locking tongue of the locking mechanism 5 to be inserted into the locking groove 6 on the recess, thus preventing external forces from easily opening the cover plate 3. As an equivalent method, the connection between the cover plate 3 and the mounting plate 1 can also be a snap-fit ​​method.

[0024] like Figures 3 to 5 As shown, further, at least one limiting member 7 is provided on the inner wall of the recess. In this embodiment, the recess has a square cross-section, and a limiting member 7 is provided at each of the four corners of the recess. The limiting member 7 plays the role of limiting and positioning, so that the cover plate 3 can not rotate further after rotating to the predetermined position. At this time, the locking tongue of the locking mechanism 5 can be inserted into the locking groove 6, which facilitates the quick locking of the cover plate 3 with the mounting plate 1.

[0025] like Figure 5 As shown, each limiting member 7 further includes a limiting part 701 and a connecting part 702. The connecting part 702 is L-shaped, and the limiting part 701 and the connecting part 702 are fixed to the side facing the cover plate 3. Specifically, the connecting part 702 is in the shape of an angle steel, and the limiting part 701 is in the shape of a plate. In this embodiment, the limiting part 701 and the connecting part 702 are integrally formed. The L-shaped connecting part 702 is fixed at the corner of the square recess. When the cover plate 3 is rotated into place, the side wall of the cover plate 3 facing the recess is tightly attached to the limiting part 701, thereby restricting the cover plate 3 from continuing to rotate.

[0026] Furthermore, the connecting part 702 is connected to the inner wall of the recessed part by screws. The connecting part 702 is fixed to the interior of the recessed part by screws, which facilitates the subsequent disassembly and replacement of the connecting part 702.

[0027] like Figure 3 and Figure 4 As shown, a protective net 8 is further provided inside the annular convex tube 2. The protective net 8 serves as a secondary protection, preventing larger debris and flying dust from entering the grain thresher. In a preferred embodiment, the protective net 8 is fixed to the mounting plate 1 on the side near the grain thresher by screws.

[0028] like Figure 3 and Figure 4 As shown, the annular convex tube 2 is further provided with an anti-slip flange 9. When an external connecting pipe is connected to the annular convex tube 2, the anti-slip flange 9 acts as a locking mechanism to prevent the connecting pipe from easily slipping off the annular convex tube 2, thus enabling the grain machine to operate stably.

[0029] This utility model also provides a grain threshold, including a housing 10 and an air outlet structure. The mounting plate 1 of the air outlet structure is detachably connected to the housing 10. A blower 11 is provided inside the housing 10, and the output end of the blower 11 is connected to an annular convex pipe 2. In this embodiment, an existing grain threshold is modified by creating a groove for mounting the mounting plate 1 at the ventilation opening of the existing grain threshold housing 10. The mounting plate 1 is connected to the housing 10, and the output end of the blower 11 is connected to the annular convex pipe 2. This device moves via wheels at its bottom. During operation, a connecting pipe is connected to the annular convex pipe 2. The blower 11 delivers gas of a predetermined temperature and humidity through the annular convex pipe 2 into the connecting pipe. The worker moves the output end of the connecting pipe to a predetermined area to treat the environment of that area, ensuring the grain is stored in a suitable environment. When not in use, the cover plate 3 is placed over the recessed portion.

[0030] Furthermore, the mounting plate 1 is screwed to the housing 10. When the grain threshing machine is being repaired, the mounting plate 1 can be removed from the housing 10 by releasing the screws. This allows for the repair of the various components on the mounting plate 1 and also provides sufficient operating space for the repair of the internal components of the grain threshing machine.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
