Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a fresh corn kernel screening device. Background Technology

[0002] In agricultural production and related industrial processes, after corn is harvested, threshing is necessary to ensure long-term and stable quality during storage. This involves separating the corn kernels from the cob. Using a corn threshing machine, the threshing task can be completed efficiently and accurately, facilitating the orderly progress of subsequent production activities. The threshing machine relies on principles such as friction threshing, using high-speed rotation to rub the corn cob, quickly and efficiently separating the corn kernels from the cob. Harvested corn may contain a lot of impurities, such as corn silk and broken corn cobs. When corn contains corn silk and broken corn cobs, these impurities occupy a lot of space, reducing the utilization rate of storage space. At the same time, they affect air permeability and humidity, increasing the difficulty and cost of storage management, and making the corn kernels more susceptible to being in a humid environment, causing them to become damp and moldy, seriously affecting the quality and value of the corn.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order 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.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a fresh corn kernel threshing and screening device. The fresh corn kernel threshing and screening device includes a main component 100 and a screening component 200. The two work together to filter impurities during corn kernel threshing and collection, reduce space occupation, reduce costs, ensure ventilation, reduce the risk of spoilage, and extend the storage period.

[0032] The main component 100 includes a thresher 101, a feed frame 102 fixed to the top of the thresher 101, and a discharge frame 103 fixed to one side of the thresher 101.

[0033] By feeding corn cobs into the thresher 101 through the feed frame 102, and then starting the thresher 101 to thresh the corn cobs, the corn kernels after threshing will be discharged through the discharge frame 103, and the corn cobs will be discharged from one side of the thresher 101. The thresher 101 is existing technology and will not be described in detail here.

[0034] The screening assembly 200 is located below the discharge frame 103 and includes a screening component 201. The screening component 201 includes a screening plate 2011. A receiving plate 2012 is located below the screening plate 2011. A collection box 2013 is located on one side of the screening plate 2011. A closing cover 2014 is hinged to the top of the collection box 2013.

[0035] When the corn kernels and debris fall onto the screening plate 2011, the closing cover 2014 will open. Both the screening plate 2011 and the receiving plate 2012 have inclined surfaces. The vibration of the screening plate 2011 can screen the corn kernels on it. The corn kernels that pass through the screen will fall onto the receiving plate 2012 and be discharged through the receiving plate 2012 for easy collection. At this time, the setting of the screening plate 2011 can transport the debris into the collection box 2013. After collection, the closing cover 2014 can be closed to seal the collection box 2013, thereby preventing external debris from entering the collection box 2013 and reducing the storage space.

[0036] Example 2

[0037] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the screening component 200 includes a movable part 202, which includes a support plate 2021. The support plate 2021 is fixed to one side of the screening plate 2011, and an elastic plate 2022 is fixed to one side of the support plate 2021.

[0039] There are four support plates 2021, which are fixed on both sides of the screening plate 2011. There are four elastic plates 2022, which are fixed on one side of the support plate 2021. The elastic plates 2022 have a certain elasticity. When the screening plate 2011 moves, it can drive the support plate 2021 to move. At this time, the support plate 2021 can squeeze the elastic plate 2022. The rebound of the elastic plate 2022 can make the screening plate 2011 vibrate back and forth to screen the corn kernels.

[0040] Specifically, a positioning plate 2023 is fixed to the bottom of the elastic plate 2022, and the positioning plate 2023 is fixed to one side of the receiving plate 2012.

[0041] There are four positioning plates 2023, which are fixed to the bottom of the elastic plate 2022. The positioning plates 2023 can support the elastic plate 2022 and prevent the elastic plate 2022 from shifting.

[0042] Specifically, a movable column 2024 is fixed on one side of the screening plate 2011, and a drive rod 2025 is provided at one end of the movable column 2024. The drive rod 2025 and the movable column 2024 are hinged together.

[0043] When the screening plate 2011 needs to be moved, the reciprocating movement of the drive rod 2025 will drive the moving column 2024 to move, and the movement of the moving column 2024 will drive the screening plate 2011 to move.

[0044] Specifically, a rotating block 2026 is hinged to one end of the drive rod 2025, and a rotating rod 2027 is fixed to one side of the rotating block 2026. The rotating rod 2027 and the receiving plate 2012 are rotatably connected by a rotating shaft.

[0045] A motor is fixed to one end of the rotating rod 2027. The motor is fixed to the inner wall of the receiving plate 2012. By starting the motor, the rotating rod 2027 can be driven to rotate. At this time, the rotation of the rotating rod 2027 can drive the rotating block 2026 to rotate. When the rotating block 2026 rotates, it can drive the drive rod 2025 to move back and forth.

[0046] Specifically, the screening assembly 200 also includes a rotating component 203, which includes a torsion spring 2031. The torsion spring 2031 is fixed to one side of the closed cover 2014, and a connecting plate 2032 is fixed to one end of the torsion spring 2031.

[0047] The connecting plate 2032 is fixed to one side of the collection box 2013. When the closing cover 2014 is closed, it can apply a torsional force to the torsion spring 2031. When the motor is started and the rotating rod 2027 is rotated, the force of the rotation of the torsion spring 2031 can drive the closing cover 2014 to open and collect the debris, preventing the debris from falling outside due to the closing cover 2014 not opening in time.

[0048] Specifically, a ratchet 2033 is fixed on one side of the closed cover 2014, and a pawl 2034 is provided on one side of the ratchet 2033. The ratchet 2033 and the pawl 2034 mesh, and a moving bar 2035 is fixed on one side of the pawl 2034.

[0049] When the cover 2014 is closed, the ratchet 2033 can be rotated. At this time, the ratchet 2033 can rotate on one side of the pawl 2034. The pawl 2034 can limit the ratchet 2033 in one direction, preventing the force of the torsion spring 2031 from causing the cover 2014 to open on its own. When the starter motor drives the rotating rod 2027 to rotate, it can drive the moving bar 2035 to move. The movement of the moving bar 2035 can cause the pawl 2034 and the ratchet 2033 to separate, thereby releasing the limit on the ratchet 2033. Then the force of the torsion spring 2031 can drive the cover 2014 to open.

[0050] Example 3

[0051] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, a movable disk 2036 is sleeved on the outside of the movable strip 2035, a first spring 2037 is fixed on one side of the movable disk 2036, a guide strip 2038 is fixed on one end of the movable strip 2035, a guide frame 2039 is sleeved on the outside of the guide strip 2038, and the guide strip 2038 and the guide frame 2039 are movably connected.

[0053] A support sleeve is provided on the outside of the moving strip 2035. The support sleeve is movably connected to the moving strip 2035. The support sleeve is fixed to one side of the collection box 2013, and one end of the first spring 2037 is fixed to the inner wall of the support sleeve. The moving strip 2035 can be supported by the support sleeve.

[0054] When the moving bar 2035 moves, it causes the pawl 2034 and ratchet 2033 to separate, which in turn causes the moving disk 2036 to move. At this time, the movement of the moving disk 2036 can apply a squeezing force to the first spring 2037. When the rotating rod 2027 stops rotating, the rebound force of the first spring 2037 can cause the moving bar 2035 to return to its original position, so that the pawl 2034 and ratchet 2033 can re-engage. A guide groove corresponding to the guide bar 2038 is provided on the guide frame 2039. By moving the guide frame 2039, the guide groove can squeeze the guide bar 2038, which can then cause the guide bar 2038 to move. The movement of the guide bar 2038 can then drive the moving bar 2035 to move.

[0055] Specifically, the screening assembly 200 also includes a driving component 204, which includes a connecting rod 2041. The connecting rod 2041 is fixed to one side of the guide frame 2039. A connecting plate 2042 is fixed to one end of the connecting rod 2041. A second spring 2043 is fixed to one side of the connecting plate 2042. One end of the second spring 2043 is fixed to the inner wall of the rotating rod 2027.

[0056] When the rotating rod 2027 rotates, it drives the connecting plate 2042 to move. At this time, the movement of the connecting plate 2042 can apply a squeezing force to the second spring 2043. The movement of the connecting plate 2042 will drive the connecting rod 2041 to move. The movement of the connecting rod 2041 can drive the guide frame 2039 to move, thereby releasing the limit on the ratchet 2033. Then the closing cover 2014 can be opened. A positioning cover is sleeved on the outside of the connecting rod 2041. The connecting rod 2041 and the positioning cover are movably connected. The positioning cover is fixed to one side of the collection box 2013. The moving strip 2035 is inserted into one side of the positioning cover. The moving strip 2035 and the positioning cover are movably connected. When the rotating rod 2027 stops rotating, the rebound force of the second spring 2043 can drive the connecting plate 2042 to return to its original position.

[0057] Specifically, a sloping panel 2044 is fixed to one side of the connecting plate 2042, an extrusion strip 2045 is provided on one side of the sloping panel 2044, and a counterweight block 2046 is fixed to one end of the extrusion strip 2045.

[0058] The extrusion strip 2045 is inserted into one side of the rotating rod 2027. The extrusion strip 2045 and the rotating rod 2027 are movably connected. When the rotating rod 2027 rotates, it can generate centrifugal force, at which time the counterweight 2046 will move. The movement of the counterweight 2046 can drive the extrusion strip 2045 to move. When the extrusion strip 2045 moves, it can extrude the inclined plate 2044. Then, the movement of the inclined plate 2044 can drive the connecting plate 2042 to move. When the rotating rod 2027 stops rotating, the centrifugal force will disappear. Then, the rebound force of the second spring 2043 will drive the connecting plate 2042 to return to its original position. At this time, the inclined plate 2044 can extrude the extrusion strip 2045 to return the counterweight 2046 to its original position for the next use.

[0059] During use, when the threshed corn kernels are discharged from one side of the discharge frame 103, the motor is started to drive the rotating rod 2027 to rotate. The rotation of the rotating rod 2027 causes the counterweight 2046 to move. The movement of the counterweight 2046 causes the extrusion bar 2045 to move. When the extrusion bar 2045 moves, it can extrude force onto the inclined plate 2044. Then, the movement of the inclined plate 2044 causes the connecting plate 2042 to move. The movement of the connecting plate 2042 can apply a compressive force to the second spring 2043. The movement of the connecting plate 2042 will drive the connecting rod 2041 to move. The movement of 41 can drive the guide frame 2039 to move. The movement of the guide frame 2039 can drive the guide groove to press against the guide bar 2038, which can then cause the guide bar 2038 to move. The movement of the guide bar 2038 can then drive the moving bar 2035 to move. The movement of the moving bar 2035 can then drive the moving disk 2036 to move. The movement of the moving disk 2036 can then apply a compressive force to the first spring 2037. The movement of the moving bar 2035 can then cause the pawl 2034 and the ratchet 2033 to separate. At this point, the force of the torsion spring 2031 rotating can then cause the closing cover 2014 to open.

[0060] Simultaneously, rotating block 2026 is rotated by rotating rod 2027. When rotating block 2026 rotates, it drives drive rod 2025 to move back and forth. The reciprocating movement of drive rod 2025 drives moving column 2024 to move. The movement of moving column 2024 drives screening plate 2011 to move. When screening plate 2011 moves, it drives support plate 2021 to move. At this time, support plate 2021 can squeeze elastic plate 2022. The rebound of elastic plate 2022 can make screening plate 2011 vibrate back and forth to screen corn kernels. The corn kernels fall onto receiving plate 2012 after screening and are discharged through receiving plate 2012 for easy collection. At this time, the setting of screening plate 2011 can transport impurities into collection box 2013.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
