Description

Technical Field

[0001] The utility model relates to the technical field of corn processing, in particular to threshing equipment for corn processing. Background Art

[0002] Corn is an important food crop. Compared with traditional food crops such as rice and wheat, corn has strong drought resistance, cold resistance, barrenness resistance and excellent environmental adaptability. As a high-yield food crop in my country, corn is an important feed source for animal husbandry, breeding, aquaculture, etc. It is also one of the indispensable raw materials for food, medical and health care, light industry, chemical industry, etc. When processing corn, it is usually threshed in advance and then the corn kernels are ground into powder; most of the existing threshing equipment for corn processing has a simple structure, which places the corn in a processing box and directly threshes it to separate the corn stalks and corn kernels. In the process of corn processing, the corn placed in the processing box is very easy to jump out of the box, which is easy to cause unnecessary danger to the operator, and the corn discharge of the existing thresher is mostly manually received, which increases labor and reduces a certain work efficiency, bringing certain adverse effects to people's use process.

[0003] After searching, the prior art disclosed (Announcement No.: CN213755783U) a threshing equipment for processing sweet and sticky corn, which records "including a thresher body, the upper end outer surface of the thresher body is fixedly installed with an explosion-proof mechanism, the middle part of the rear end outer surface of the thresher body is fixedly connected with a corn stalk outlet, the front end outer surface of the thresher body is provided with a corn kernel outlet and a receiving box, the outer surface of one side of the thresher body is fixedly installed with a motor mechanism, and the explosion-proof mechanism includes a baffle, a hinge, a tempered glass cover and a handle."; The equipment effectively prevents corn kernels from jumping out of the thresher through the explosion-proof mechanism. The main body of the corn thresher brings unnecessary harm to the operator, while also reducing the waste of corn resources and increasing work efficiency. The whole and broken corn can be directly separated through the setting of the receiving box, which makes the corn threshing effect better, reduces the manual labor of the operator, increases the functionality of the corn thresher and improves the use effect. However, the receiving box of the equipment lacks a corresponding cleaning structure, so that after a layer of whole corn is covered on the upper surface of the mesh partition, the broken corn that subsequently falls into the receiving box cannot pass through the mesh partition, causing the whole and broken corn to mix with each other, and then the setting of the mesh partition and the drawer box becomes ineffective, reducing the overall quality of the corn kernels.

[0018] Reference Figures 1 to 4 As shown, the utility model provides a threshing equipment for corn processing, including: a screening component 4, the lower end of the side of the thresher body 1 is fixedly connected to the screening component 4, and the discharge pipe 2 arranged on the side of the thresher body 1 is opposite to the feed port opened on the upper surface of the screening component 4, the screening component 4 is composed of a shell 10, a filter plate 9 and a rotating column 7, and the upper surface of the shell 10 is fixedly connected to the main motor 6, the main motor 6 is connected to the rotating column 7 through a coupling, and the filter plate 9 is fixedly connected to the inside of the shell 10, and the two ends of the rotating column 7 are respectively movably connected to the filter plate 9 and the top of the inner cavity of the shell 10 through bearings, and at the same time, the side of the rotating column 7 is symmetrically connected to the moving plate 8, and a through hole is opened on the surface of the filter plate 9, and the lower surface of the filter plate 9 is fixedly connected to the discharge plate 11 near the through hole, and the lower end of the inner cavity of the shell 10 is movably connected to the recovery box 5 through the loading and unloading port.

[0019] In this embodiment, corn is put into the interior of the threshing machine main body 1, and the corresponding switch of the threshing machine main body 1 is started. Then, the threshing machine main body 1 can put the corn kernels of the corn into the housing 10 of the screening assembly 4 through the discharge pipe 2. At this time, the switch of the main motor 6 is started, and the output shaft of the main motor 6 drives the fixedly connected rotating column 7 and the moving plate 8 to rotate synchronously through the coupling. Therefore, the continuously input corn kernels inside the housing 10 can be divided into relatively independent different corn kernel piles by multiple moving plates 8. When the moving plate 8 pushes the corn kernel pile to rotate, the broken corn kernels mixed in the corn kernel pile can fall into the recycling box 5 through the filter plate 9, while the whole corn kernels will be pushed by the moving plate 8 to the through-hole, so that the whole corn kernels can be output through the discharge plate 11, improving the quality of the corn kernels produced by the threshing equipment and eliminating the subsequent manual screening process. Workers can take out the recycling box 5 to perform corresponding secondary processing on the broken corn kernels, reducing waste of resources.

[0020] At the same time, the relevant structures and working principles of the threshing machine main body 1 in this application are all existing mature technologies and have been fully disclosed in a threshing equipment for processing sweet glutinous corn (publication number: CN213755783U).

[0022] In this embodiment, as Figure 2 、 Figure 3 and Figure 4 , the setting of the baffle 3 can perform corresponding shielding and limiting treatment on the corn kernels output by the discharge pipe 2, and then can effectively avoid the problem of accidental scattering of the corn kernels, ensuring that all the corn kernels output by the discharge pipe 2 can fall into the interior of the housing 10 and reducing the waste rate of resources.

[0024] In this embodiment, as Figure 2 、 Figure 3 and Figure 4 , the through-holes opened on the filter plate 9 enable the whole corn kernels to smoothly fall into the discharge plate 11 for output, and the feed inlet opened on the housing 10 and the through-holes opened on the filter plate 9 are distributed at a right angle. Therefore, the moving path of the corn kernels on the surface of the filter plate 9 can be extended, thereby improving the screening effect of the filter plate 9 on the whole corn kernels and the broken corn kernels.

[0025] As a preferred embodiment, the rotating column 7 is a cylindrical structure, the axial length of the rotating column 7 is equal to the distance from the upper surface of the filter plate 9 to the top of the inner cavity of the shell 10, and the arc surface of the rotating column 7 is circumferentially surrounded by four groups of movable plates 8 fixedly connected at equal intervals.

[0026] In this embodiment, if Figure 2 and Figure 4 The size of the rotating column 7 allows the rotating column 7 to rotate stably within the shell 10, and the setting of the movable plate 8 allows the corn kernels put into the shell 10 to be divided into batches of small corn kernel piles, thereby improving the efficiency and effect of corn kernel crushing and separation.

[0027] As a preferred embodiment, the movable plate 8 has a rectangular structure, and one end of the movable plate 8 away from the rotating column 7 is slidably connected to the side of the inner cavity of the shell 10, and the radial cross-section formed by the combination of the movable plate 8 and the rotating column 7 has a cross-shaped structure, and the length of the movable plate 8 is equal to the axial length of the rotating column 7.

[0028] In this embodiment, if Figure 2 and Figure 4 The size of the movable plate 8 is set so that the upper end of the inner cavity of the shell 10 can be divided into relatively independent cavities, thereby avoiding the corn kernels between different cavities from mixing with each other, and also ensuring the pushing effect of the movable plate 8 on the corn kernels, avoiding the corn kernels from clogging the mesh of the filter plate 9.

[0029] As a preferred embodiment, the discharge plate 11 is composed of an inclined plate and a side plate. The inclined plate is a long strip structure, and the two sets of side plates are right-angled triangle structures. The cross-section of the discharge plate 11 is a U-shaped structure, and a through groove is provided on the side of the shell 10 corresponding to the position of the discharge plate 11, and the upper surface of the side is fixedly connected to the lower surface of the filter plate 9.

[0030] In this embodiment, if Figure 2 , Figure 3 and Figure 4 The structural setting of the discharge plate 11 can effectively enhance the safety of the whole corn kernels during output, ensure that the whole corn kernels can move in a directional manner, and avoid the problem of the whole corn kernels accidentally scattering or accidentally falling into the recovery box 5.

[0031] As a preferred embodiment, the recovery box 5 has a square structure, the embedded end of the recovery box 5 has a semicircular structure, and the size of the embedded end of the recovery box 5 is compatible with the size of the lower end of the inner cavity of the shell 10. At the same time, the bottom of the inner cavity of the recovery box 5 is fixedly connected to the auxiliary plate 12, and the end of the auxiliary plate 12 away from the embedded end is inclined downward.

[0032] In this embodiment, if Figure 3 and Figure 4The setting of the recovery box 5 makes it convenient for workers to carry out unified and rapid secondary processing of the screened broken corn kernels, eliminating the process of workers loading the broken corn kernels.
