Description

Technical Field

[0001] The utility model relates to a screening device, in particular to a screening device for pepper processing. Background Art

[0002] The raw materials of chili peppers in the factories of chili product manufacturers are usually mixed with impurities such as chili branches, chili leaves, weeds, mud and sand, chili debris, dust, etc. During the production and processing of chili products, in order to ensure the quality of the production and processing of chili products, it is first necessary to use a screening device to screen and remove impurities from the chili peppers, and then carry out subsequent processing operations.

[0003] The existing screening device usually includes a shell with a feed inlet and a discharge port, a screen disposed in the shell, and a driving mechanism for driving the screen to vibrate upward and downward. The working principle of the screening device is: the driving mechanism is used to drive the screen to vibrate upward and downward, so that impurities in the peppers are screened out from the mesh holes in the screen, and the peppers remaining on the screen are the screened peppers. However, in the actual screening process of peppers, since the peppers contain weeds, pepper leaves and other impurities whose size is larger than the mesh size in the screen, such impurities cannot be effectively screened out by the screen in the screening device, which will lead to poor screening effect of peppers and seriously affect the production quality of pepper products. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a screening device for pepper processing, so as to achieve the purpose of improving the screening effect and improving the production quality of pepper products.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a screening device for processing peppers, comprising an inclined transport mechanism capable of conveying peppers and pre-screened small impurities, an interception mechanism arranged above the transport surface in the transport mechanism for re-screening large impurities, and a winnowing mechanism vertically arranged on the ground for supplementary screening of impurities, wherein the bottom of the front end of the transport mechanism is arranged on the ground through a front end base, the end of the transport mechanism is fixed on the winnowing mechanism, and the height of the end of the transport mechanism is greater than the height of the front end of the transport mechanism.

[0006] As defined in the present invention, the intercepting mechanism includes two brackets relatively fixed on both sides of the transport mechanism, a rotating shaft rotatably arranged between the two brackets, an intercepting frame fixed on the rotating shaft, and a driving mechanism fixed on the front end base and transmission connected to the rotating shaft.

[0007] As a further limitation of the present invention, the interception frame includes two annular components respectively fixed at both ends of the rotating shaft and a plurality of interception plates fixed between the two annular components, and a plurality of interception rods are fixed between each interception plate and the rotating shaft.

[0008] As another limitation of the present utility model, the air separation mechanism includes a blast pipe vertically arranged on the ground through a rear base, an air inlet pipe connected to the lower end of the blast pipe, a blower capable of adjusting the wind speed and connected to the air inlet pipe, a discharge pipe connected to the lower end of the blast pipe, a feed pipe connected to the upper end of the blast pipe, an impurity collection box for collecting impurities connected to the upper end of the blast pipe, and an air outlet pipe connected to the top of the blast pipe. A filter member is inclined in the blast pipe to screen out impurities and allow the chili peppers to enter the discharge pipe.

[0009] As a further limitation of the present utility model, a retaining mechanism for preventing chili peppers from slipping is provided at the front end of the transportation mechanism. The retaining mechanism includes two vertical plates respectively fixed on both sides of the front end of the transportation mechanism and a connecting plate fixed between the front ends of the two vertical plates.

[0010] As a still further limitation of the present utility model, a plurality of universal wheels with self-locking functions are fixedly provided at the bottom of the front base and the bottom of the rear base.

[0011] Due to the adoption of the above technical solutions, compared with the prior art, the beneficial effects obtained by the present utility model are as follows:

[0012] (1) The present utility model is provided with a transportation mechanism, an interception mechanism and an air separation mechanism. Among them, the transportation mechanism can transport chili peppers and initially screen out smaller impurities such as sediment particles and chili pepper debris. The interception mechanism can screen out larger impurities such as weeds and chili pepper branches with larger sizes by interception. The air separation mechanism can supplement and screen out lighter impurities such as chili pepper leaves and dust. It can effectively screen out various impurities contained in chili peppers, has a good effect on screening chili peppers, and thus can effectively improve the production quality of chili pepper products.

[0013] (2) The structure of the interception mechanism in the present utility model is simple, the manufacturing cost is low, and the effect of intercepting impurities is good. The driving mechanism drives the rotating shaft and the interception frame to rotate simultaneously, so that weeds and chili pepper branches with larger sizes can be separated from the chili peppers, thereby realizing the screening of large impurities.

[0014] (3) The air separation mechanism in the present utility model adopts a structural form combining a blast pipe, an air inlet pipe, a blower, a discharge pipe, a feed pipe, an impurity collection box, an air outlet pipe and a filter member. After the chili peppers are screened by the transportation mechanism and the interception mechanism, they enter the blast pipe from the feed pipe. During the process of the chili peppers falling in the blast pipe, impurities with relatively light weights such as dust and chili pepper leaves will enter the impurity collection box along with the wind, realizing the separation of the chili peppers from the impurities and thus completing the supplementary screening of the impurities. Thereafter, the chili peppers pass through the filter member to complete the final supplementary screening and are discharged from the discharge pipe. The air separation mechanism can supplement and screen out impurities that cannot be screened out by the transportation mechanism and the interception mechanism, and can further improve the screening effect of the present utility model.

[0015] (4) The utility model is provided with a surrounding mechanism. A certain amount of peppers can be temporarily contained in the space enclosed by the surrounding mechanism and the transport surface in the transport mechanism, preventing the peppers placed on the transport mechanism from slipping, and effectively improving the practicability of the utility model.

[0016] (5) The utility model is provided with universal wheels with a self-locking function, which can conveniently move the utility model to the required position. When the utility model is in place, the universal wheels can be locked, so that the utility model is stably placed on the ground. On the premise of ensuring the convenience of movement, the stability of placement can also be ensured, effectively improving the convenience and practicability of the use of the utility model.

[0017] In summary, the utility model has a simple structure, is easy to use, and has strong practicability. Through multiple screenings of the transport mechanism, the interception mechanism and the air separation mechanism, various impurities contained in the peppers can be effectively screened out, and the screening effect of the peppers is good, thereby effectively improving the production quality of pepper products. The utility model is suitable for use in screening peppers during pepper processing. BRIEF DESCRIPTION OF THE DRAWINGS
