Description

Technical Field

[0001] This utility model relates to the field of grain and oil raw material processing, specifically to a grain and oil raw material drying box. Background Technology

[0002] A drying box for grain and oil raw material processing is a device used to reduce the moisture content of grain and oil raw materials, such as cereals and oilseeds. The purpose of the drying box is to reduce the moisture content of the raw materials to a safe storage level, prevent mold and pests, improve storage stability, extend storage time, and avoid spoilage. In addition, it can also improve processing efficiency. Drying the raw materials to a suitable moisture content is helpful for subsequent processing, such as milling and pressing, which can ensure product quality and ensure the taste and nutritional value of the final product.

[0003] Current grain and oil raw material drying boxes generally provide heat sources through electric heating, gas heating, or steam heating. Hot air is sent into the drying box using a fan or blower. The hot air comes into contact with the raw materials and removes moisture. To promote sufficient contact between the hot air and the grain and oil raw materials, a stirring device is usually installed. The stirring device can make the raw materials dry more evenly and thoroughly. However, the stirring device is generally installed in a fixed manner. In actual use, in order to improve drying efficiency, the capacity of the drying box is relatively large. This leads to dead corners that are easy to form inside the drying box. The grain and oil raw materials in these areas are not fully stirred and dried, resulting in insufficient drying of the grain and oil raw materials, which affects subsequent production efficiency and product quality. Utility Model Content

[0004] To address the aforementioned problems, the main objective of this utility model is to provide a grain and oil raw material drying box that can thoroughly dry the grain and oil raw materials inside the drying box, thereby improving the quality of grain and oil products and production efficiency.

[0005] To achieve the above objectives, this utility model provides a grain and oil raw material drying box, including a hot air box and a drying chamber connected by a pipe. The drying chamber includes a hot air cavity, a storage box, and a cover. The storage box is located above the hot air cavity, and the cover is fastened to the upper end of the storage box. The bottom of the storage box is provided with a vent hole, and the storage box is connected to the hot air cavity through the vent hole. The storage box is provided with a stirring device, a driving device, and a track device. The stirring device moves horizontally along the length of the storage box.

[0006] Furthermore, the stirring device includes a rotating shaft and several stirring blades evenly distributed on the outer peripheral wall of the rotating shaft, and the rotating shaft has a cylindrical structure.

[0007] Furthermore, the track device includes a first slide rail, a slider, a connecting rod, a moving part, a second slide rail, an upper pulley, and a lower pulley. The length of the connecting rod is greater than the length of the rotating shaft, and the connecting rod is sleeved inside the rotating shaft.

[0008] Furthermore, the first slide rail is fixed along the length of the inner wall of the storage box, the slider moves within the first slide rail, one end of the connecting rod is connected to the slider, and the other end is connected to the moving part.

[0009] Furthermore, the drive device includes a first driver, a drive gear, a driven gear, a transmission chain, a support frame, a second driver, a mounting frame, and a threaded rotating rod. The threaded rotating rod is rotatably disposed inside the storage box on the side opposite to the first slide rail, parallel to the first slide rail.

[0010] Furthermore, the driven gear is fixed on one end of the rotating shaft near the threaded rod, the driving gear is located on the output shaft of the first driver, and the transmission chain connects the driving gear and the driven gear respectively.

[0011] Furthermore, the second driver is fixed on the mounting bracket and located outside the storage box. The output end of the second driver passes through the storage box and is rotatably connected to one end of the threaded rod. The moving part is screwed onto the outer peripheral wall of the threaded rod.

[0012] Furthermore, the support frame includes a support plate and a side baffle. The side baffle is fixed to the outer side of the support plate. The first drive is mounted on the support plate.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1The diagram shows the overall structure of the grain and oil raw material drying box of this utility model. The drying box includes a hot air box 10 and a drying chamber connected by a pipe 11. The drying chamber includes a hot air cavity 20, a storage box 30, and a cover 40. The hot air box 10 is directly connected to one end of the hot air cavity 20 via the pipe 11. The hot air generated inside the hot air box 10 is moved into the hot air cavity 20 by a blower or other air-blowing structure. The storage box 30 is located above the hot air cavity 20, and the cover 40 is fastened to the upper end of the storage box 30. The area of ​​the lower end surface of the storage box 30 is the same as the area of ​​the upper end surface of the hot air cavity 20. Figure 2 As shown, in this embodiment, the bottom of the storage box 30 is provided with several ventilation holes 31. The hot air flow in the hot air cavity 20 enters the storage box 30 through the ventilation holes 31 to dry the grain and oil raw materials in the storage box 30. In other embodiments, the hot air cavity 20 is provided with an upper end face, which is also provided with several ventilation holes 31. The hot air in the hot air cavity 20 first passes through the ventilation holes 31 on the hot air cavity 20, and then through the ventilation holes 31 at the bottom of the storage box 30 to heat exchange and dry the raw materials. This arrangement can prevent small particulate impurities in the raw materials in the storage box 30 from directly entering the hot air cavity 20 through the ventilation holes 31 provided on it. Since the hot air in the hot air cavity 20 is flowing, a large amount of dust will accumulate in the hot air cavity 20, causing air pollution.

[0033] Please see Figure 2 The diagram shows a partial structural schematic of the grain and oil raw material drying box of this utility model. The storage box 30 of the drying box is equipped with a stirring device 50, a driving device, and a track device. The stirring device 50 can move horizontally along the length of the storage box 30 through the action of the driving device and the track device, that is, it reciprocates along the direction of the arrow in the diagram. Additionally, as shown... Figure 2 As shown, the bottom inner side of the storage box 30 has two curved ends along the length direction. The stirring device 50 can fully stir all the grain and oil raw materials in the storage box 30 along the length and width directions, so that the product is dried more evenly and thoroughly.

[0034] Please also refer to Figure 2 and Figure 3 As shown, the stirring device 50 of this utility model is provided with a rotating shaft 51 and a plurality of stirring blades 52 evenly distributed on the outer peripheral wall of the rotating shaft 51. The rotating shaft 51 has a cylindrical structure. Please refer to... Figure 4As shown, the track device of this utility model includes a first slide rail 61, a slider 62, a connecting rod 63, a moving part 64, a second slide rail 65, an upper pulley 66, and a lower pulley 67. The length of the connecting rod 63 is greater than the length of the rotating shaft 51, and the connecting rod 63 is sleeved inside the rotating shaft 51. The first slide rail 61 is fixed along the length of the inner wall of the storage box 30. The slider 62 moves within the first slide rail 61. After the connecting rod 63 passes through the hollow cylindrical body of the rotating shaft 51, one end of it is connected to the slider 62, and the other end is connected to the moving part 64 (e.g., ...). Figure 6 (As shown).

[0035] Please see Figure 5 and Figure 6 As shown, the drive device of this utility model includes a first driver 71, a driving gear 72, a driven gear 73, a transmission chain 74, a support frame 75, a second driver 76, a mounting frame 77, and a threaded rotating rod 78. The threaded rotating rod 78 is rotatably disposed inside the storage box 30 on the opposite side of the first slide rail 61, parallel to the first slide rail 61. The second driver 76 is fixed on the mounting frame 77 and located on the outside of the storage box 30. The output end of the second driver 76 passes through the storage box 30 and is rotatably connected to one end of the threaded rotating rod 78. The moving part 64 is screwed onto the outer peripheral wall of the threaded rotating rod 78.

[0036] Furthermore, such as Figure 5 and Figure 6 As shown, the driven gear 73 is fixed on the rotating shaft 51 near one end of the threaded rod 78. The driving gear 72 is rotatably connected to the output shaft of the first driver 71. The transmission chain 74 connects the driving gear 72 and the driven gear 73 respectively. Thus, after the first driver 71 is started, it drives the driving gear 72 to rotate, and through the transmission chain 74, it drives the driven gear 73 to rotate. Figure 2 As shown, since the driven gear 73 is fixedly connected to the outer wall of the rotating shaft 51, the rotating shaft 51 rotates accordingly, causing the stirring blades 52 on its outer periphery to rotate and stir. Since the stirring blades 52 are evenly distributed on the rotating shaft 51, the grain and oil raw materials in the storage box 30 in the width direction can be fully stirred.

[0037] Please refer to this again. Figure 4 As shown, the second slide rail 65 of this utility model is fixed on the outer side of the storage box 30 opposite to the threaded rotating rod 78. The support frame 75 is provided with a support plate 751 and a side baffle 752. The side baffle 752 is fixed on the outer side of the support plate 751. The first driver 71 is fixedly installed on the support plate 751. The upper pulley 66 and the lower pulley 67 are located on the inner side of the side baffle 752 and below the support plate 751, respectively. Specifically, the lower pulley 67 is slidably embedded in the second slide rail 65, and the upper pulley 66 slides on the upper surface of the second slide rail 65. In addition, as shown in the figure... Figure 6As shown, the upper end of the movable part 64 is fixedly connected to the lower bottom surface of the support plate 751 and the end away from the side baffle 752. It should be noted that the support plate 751 spans across the edge corresponding to the storage box 30 and does not abut against the edge.

[0038] Therefore, please also refer to Figure 2 , Figure 4 and Figure 5 As shown, when the second driver 76 is started, the driver drives the threaded rotating rod 78 to rotate, and at the same time causes the movable part 64 screwed onto the threaded rotating rod 78 to move along the length direction of the storage box 30. Since the support plate 751 is fixedly connected to the movable part 64, and the upper pulley 66, the lower pulley 67, and the second slide rail 65 limit the movement, the support plate 751 can move stably along the displacement direction of the movable part 64. This satisfies the requirement that the stirring device 50 can not only fully stir the material in the width direction of the storage box 30, but also moveably stir the material in the length direction of the storage box 30. At the same time, the two ends of the bottom inner side of the storage box 30 along the length direction are arc-shaped surfaces, which can fit with the stirring blades 52 of the stirring device 50 to prevent dead corners from appearing at the bottom of the storage box 30 that cannot be turned over for stirring.

[0039] It should also be noted that, as Figure 1 As shown, the grain and oil raw material drying box of this utility model is also equipped with a dehumidification system 80, which is installed on the cover 40. The dehumidification system 80 can discharge humid air and keep the inside of the storage box 30 dry. In addition, the storage box 30 is also equipped with a feed inlet and a discharge outlet, which are not shown in the figure. The grain and oil raw materials can enter the storage box 30 from the feed inlet at the top, and after drying, they can be discharged from the discharge outlet at the bottom or side for collection. Furthermore, the drying box of this utility model is also equipped with a control system, a temperature sensor, and a humidity sensor. The temperature and humidity inside the storage box 30 are adjusted by the temperature and humidity sensors and the control system to ensure a good drying effect. All electrical components in this utility model are electrically connected to the control system and the power supply. The control method is controlled by the control system. The control circuit of the control system can be implemented by those skilled in the art through simple programming. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
