Description
Technical Field
[0001] This utility model relates to the field of roasting machine technology, specifically a dustproof and splashproof roasting machine. Background Technology
[0002] Roasting machines are specialized equipment used in the food processing industry for roasting nuts, seeds, grains, and other materials. Dustproof and splashproof roasting machines typically consist of a closed roasting system, dustproof and splashproof devices, and an intelligent control system. During the roasting process, the high-speed rotation of the drum generates centrifugal force, causing the material to move closely against the inner wall. The alternating forward and reverse rotations achieve three-dimensional tumbling of the material in all directions. Dustproof and splashproof roasting machines are widely used in food processing, traditional Chinese medicine processing, laboratories, and small workshops.
[0003] For example, Chinese patent CN218869358U, entitled "A Roasting Machine," includes a mounting box and a rotatable drum disposed inside the mounting box. The open end of the drum passes through the mounting box and is located outside the mounting box. The mounting box is provided with a drive assembly for driving the drum to rotate and a heating assembly for heating the drum. The mounting box is provided with a slag collection box located above the open end of the drum. The slag collection box has multiple through holes. The mounting box is provided with a draft assembly communicating with the slag collection box. The draft assembly includes a draft fan and a dust collector. The dust collector is connected to the slag collection box through a first pipe. The suction end of the draft fan is connected to the dust collector through a second pipe. The exhaust end of the draft fan is provided with a dust collection bag. A baffle is inclinedly provided inside the dust collector, and the baffle is located between the first pipe and the second pipe.
[0004] While the aforementioned existing technologies can enable the use of roasting machines, in actual use, on the one hand, the dust prevention effect of the roasting machine is not good enough. Usually, the feed inlet of the roasting machine is in a normally open state, which makes it easy for dust in the air to enter the roasting machine. On the other hand, the roasted goods are easy to overflow from the roasting machine. Usually, the roasting machine is set horizontally, which makes it easy for the roasted goods to overflow from the roasting machine during the roasting process. Therefore, it does not meet the current needs. In this regard, we propose a dustproof and splashproof roasting machine. Utility Model Content
[0005] The purpose of this utility model is to provide a dustproof and splashproof roasting machine to solve the problems mentioned in the background art, such as the insufficient dustproof effect of the roasting machine and the easy overflow of roasted goods from the roasting machine.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and splashproof roasting machine, comprising a base, a box body above the base, a stir-frying chamber inside the box body, an open structure on one side of the stir-frying chamber, a stir-frying cylinder inside the stir-frying chamber, a fixing plate fixedly mounted on the side of the stir-frying cylinder located at the opening of the stir-frying chamber, an installation cavity at the center of one side of the fixing plate, the installation cavity having a through structure and communicating with the stir-frying cylinder, a dustproof plate inside the installation cavity, slots provided at the upper and lower ends of the dustproof plate and at the upper and lower ends of one side of the fixing plate, the slots on the dustproof plate corresponding to the slots on the fixing plate.
[0007] Preferably, the fixing plate is provided with a plug rod at the upper end of the slot opening, the plug rod extends through the slot into the interior of the dustproof plate, and a return spring is sleeved on the outside of the plug rod, with the upper and lower ends of the return spring connected to the plug rod and the housing respectively.
[0008] Preferably, a first mounting seat is provided on both the front and rear ends of the outer side of the box body. The first mounting seat is rotatably connected to the box body. A hydraulic telescopic device is fixedly provided at the lower end of the first mounting seat located on one side of the box body. A second mounting seat is fixedly provided at the lower end of the fixed end of the hydraulic telescopic device. A mounting ear plate is fixedly provided at the upper end of the base located outside the second mounting seat. The mounting ear plate is rotatably connected to the second mounting seat.
[0009] Preferably, a support rod is fixedly installed at the lower end of the first mounting base located on the other side of the housing, and the lower end of the support rod is fixedly connected to the base.
[0010] Preferably, the housing has a rotating cavity inside both sides of the stir-frying cylinder, and the rotating cavity is connected to the stir-frying cavity. Limiting rings are fixedly installed on both sides of the outside of the stir-frying cylinder, and the limiting rings extend into the inside of the rotating cavity. Several balls are provided on both sides of the outside of the limiting rings, and the balls are in contact with the inside of the rotating cavity and are evenly distributed.
[0011] Preferably, a drive motor is fixedly installed on one side of the outer side of the box, and the output shaft of the drive motor extends into the interior of the box and is fixedly connected to the stirring cylinder.
[0012] Preferably, a control panel is fixedly installed at the center of the front end of the housing, and the control panel is electrically connected to the drive motor and the hydraulic telescopic device.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can cover the opening of the installation cavity by using a dustproof plate and a plug rod. Before stir-frying the goods, the goods have been poured into the stir-frying cylinder. At this time, the operator pulls the plug rod so that one end of the plug rod enters the slot on the fixed plate. Then, the dustproof plate is aligned with the opening of the installation cavity and pushed into the installation cavity so that the slot on the dustproof plate corresponds to the slot on the fixed plate. At this time, the operator releases the plug rod so that the return spring resets. The force generated by the reset spring drives the plug rod to move until one end of the slot enters the dustproof plate through the slot, thus fixing the dustproof plate and preventing dust from the external environment from entering the interior of the stir-frying cylinder through the opening.
[0015] (2) This utility model can adjust the tilt angle of the box body by means of a hydraulic telescopic device and mounting ear plates. Before stir-frying, the stir-frying goods have been poured into the stir-frying cylinder and dustproof plates have been installed. At this time, the hydraulic telescopic device is turned on by the control panel, so that the telescopic end of the hydraulic telescopic device extends. The extension of the telescopic end of the hydraulic telescopic device drives one side of the box body to move upward until the box body is adjusted to a suitable tilt angle. During this process, the first mounting seat rotates outside the box body and the second mounting seat rotates between the mounting ear plates, thereby preventing the stir-frying goods from overflowing from the opening of the stir-frying cylinder.
[0016] (3) This utility model can keep the stir-frying drum rotating when tilted by ball bearings and a limiting ring. When stir-frying the goods, the box has been adjusted to a tilted state. At this time, the drive motor is turned on by the control panel, so that the output shaft of the drive motor drives the stir-frying drum to rotate. At the same time, the limiting ring on the stir-frying drum rotates in the rotating cavity, and the ball bearings on the limiting ring contact the inner wall of the rotating cavity, so that the ball bearings roll on the inner wall of the rotating cavity, thereby preventing the limiting ring from directly contacting the inner wall of the rotating cavity after the box is tilted, thereby improving the stability of the stir-frying drum rotation.
