[0002] After fresh corn is picked, it is generally necessary to remove the small grains and immature grains at the head of the corn cob and the tail of the corn before subsequent processing and packaging to improve the quality of the corn.

[0003] At present, there are some corn head and tail cutting devices on the market, which can achieve the cutting of corn head and tail. These devices generally use chains to drive the tray to move, and two cutters are installed at specific positions. The two cutters are kept at a certain distance, and the two cutters can achieve the cutting of the head and tail of most corns.

[0004] However, corns vary in length. For some shorter corns, the distance between the two cutters may be greater than the length of the corn, resulting in that only one end of the shorter corn can be cut off. The other end needs to be cut off manually or the corn needs to be rearranged to cut off the other end, which is cumbersome. Based on this, the present application proposes a corn head and tail removal device. Utility Model Content

[0030] The embodiment of the present application provides a corn head and tail removal device, such as Figure 1 As shown, it includes a base frame 100, a main cutting knife assembly 300, an auxiliary cutting knife assembly 400, a distance sensor 500 and a controller (not shown in the figure), wherein the base frame 100 is a structure for installing and supporting other components, the main cutting knife assembly 300 can achieve cutting of most corns, the auxiliary cutting knife assembly 400 can achieve cutting of shorter corns, the distance sensor 500 can measure the distance between the corn and the distance sensor 500, thereby knowing the position of the corn head, and the controller can realize automatic control of the components.

[0031] like Figure 1 As shown, the base frame 100 is rotatably connected to a plurality of sprockets 110, which are transmission-connected to a driving motor 120, and the sprockets 110 are connected via chains 130, on which a plurality of supporting trays 200 are arranged. When the driving motor 120 is started, the chains 130 can drive the supporting trays 200 to move.

[0032] like Figure 2 As shown, the main cutting knife assembly 300 includes a knife shaft 310, two main knife discs 320 and a main cutting motor 330. The knife shaft 310 is rotatably connected to the base frame 100. The two main knife discs 320 are arranged on the knife shaft 310 and are located at both ends of the supporting tray 200. The main cutting motor 330 is transmission-connected to the knife shaft 310. When the main cutting motor 330 is started, it can drive the two main knife discs 320 to cut, thereby achieving the cutting of the head and tail of the corn.

[0033] like Figure 3 As shown, the auxiliary cutting knife assembly 400 includes a lifting cylinder 410, a support plate 420, an auxiliary cutting motor 430 and an auxiliary knife disc 440. The lifting cylinder 410 is vertically arranged on the base frame 100, and the support plate 420 is arranged on the cylinder rod of the lifting cylinder 410. The auxiliary knife disc 440 is rotatably connected to the support plate 420 and is driven by the auxiliary cutting motor 430. The auxiliary knife disc 440 is closer to the supporting tray 200 than the main knife disc 320. When the lifting cylinder 410 is retracted, the auxiliary knife disc 440 is located above the corn and will not cut the corn. When the lifting cylinder 410 is extended, the auxiliary knife disc 440 descends, so that the head of the shorter corn can be cut.

[0034] like Figure 1As shown, the distance sensor 500 is used to measure the distance between the corn in the tray 200 and the distance sensor 500, so as to know the length and position of the corn.

[0035] The distance sensor 500, the lifting cylinder 410 and the auxiliary cutting motor 430 are all electrically connected to the controller. When the distance measured by the distance sensor 500 is greater than the predetermined distance, that is, the distance between the corn and the distance sensor 500 is greater than the predetermined distance, the corn is shorter at this time. The controller controls the lifting cylinder 410 to extend so that the auxiliary knife disc 440 can cut the head of the shorter corn. The auxiliary cutting motor 430 is started to rotate the auxiliary knife disc 440, thereby achieving the cutting of the shorter corn.

[0036] It should be noted that when the operator puts the corn into the tray 200, the tail of the corn should be basically aligned with one end of the tray 200, which is convenient for the main blade 320 to cut and for the distance sensor 500 to measure the length of the corn, and the measurement of the length of the corn is more accurate. In addition, corn shorter than the tray 200 does not need to be put in, because the length of such corn is very short and has no selling value, and it is impossible to complete the cutting of the head and tail of the corn.

[0037] The distance between the corn and the distance sensor 500 measured by the distance sensor 500 has an upper limit value. When the corn just leaks out of the tray 200, the measured distance is the maximum, which is approximately equal to the distance between the tray 200 and the distance sensor 500. When the distance measured by the distance sensor 500 is greater than the maximum distance, the tray 200 does not hold corn or the distance between two trays 200 is measured. In this case, the controller does not need to control the lifting cylinder 410 and the auxiliary cutting motor 430 to operate.

[0038] When in use, the operator puts the corn into the tray 200 so that the tail of the corn is basically aligned with one end of the tray 200. The tray 200 moves under the action of the chain 130 and moves to the main cutter assembly 300 to achieve cutting of the head and tail of the corn. The distance between the two main cutter discs 320 of the main cutter assembly 300 is suitable for most lengths of corn. When the length of the corn is shorter, the main cutter assembly 300 can only cut to the tail end of the corn. At this time, the distance sensor 500 detects that the length of the corn is shorter, and the controller can control the lifting cylinder 410 in the auxiliary cutter assembly 400 to extend, drive the auxiliary cutter disc 440 to descend, and the auxiliary cutting motor 430 is started. The auxiliary cutter disc 440 is closer to the tray 200, so that the head of the shorter length of corn can be cut.

[0039] Compared with the prior art, the main cutting knife assembly 300 of the corn head and tail removal device can achieve the cutting of most corns, and the auxiliary cutting knife assembly 400 can achieve the cutting of shorter corns, thereby avoiding manual removal of the corn head or rearranging the cutting, simplifying the operation and being easy to use.

[0040] In some embodiments, the predetermined distance is the distance between the distance sensor 500 and the main blade disc 320 close to it. When the distance measured by the distance sensor 500 is greater than the predetermined distance, it means that the corn is shorter at this time, and the main blade disc 320 cannot cut the head of the corn, and the auxiliary blade disc 440 needs to be started for cutting.

[0041] In some embodiments, Figure 1 As shown, the base frame 100 is provided with a material pressing plate 140, which is located at the main cutting knife assembly 300 and the auxiliary cutting knife assembly 400. There is a small distance between the material pressing plate 140 and the corn in the tray 200, and the main cutting knife disc and the auxiliary cutting knife disc 440 are cut to press the corn so that the corn will not roll out of the tray 200.

[0042] In some embodiments, Figure 4 As shown, a clamping groove 210 is provided at one end of the tray 200. The clamping groove 210 is used to clamp the tail protrusion of the corn. The clamping groove 210 can play a positioning role, which is convenient for placing the corn and also makes the corn placed basically flat, which is convenient for subsequent cutting and measurement.

[0043] In some embodiments, Figure 5 As shown, a material guide inclined plate 150 is provided at one end of the base frame 100 close to the main cutting knife assembly 300, and a material collection box 160 is provided at the lower end of the material guide inclined plate 150. When the cut corn moves to the end of the base frame 100, it will fall from the supporting tray 200 due to the downward opening of the supporting tray 200, fall onto the material guide inclined plate 150, and then be collected in the collecting box 160.

[0044] In some embodiments, Figure 5 As shown, it also includes a collection box 170, which is arranged below the main cutting knife assembly 300 and the auxiliary cutting knife assembly 400. After the main knife disc 320 and the auxiliary knife disc 440 cut the corn, the waste cut off from the head and tail of the corn can fall into the collection box 170, which is convenient for waste collection and management.

[0045] In some embodiments, Figure 5 As shown, it also includes a shield 180, which is arranged on the main cutting knife assembly 300 and the auxiliary cutting knife assembly 400, so that the main cutting knife assembly 300 and the auxiliary cutting knife assembly 400 are covered to avoid accidental contact with the cutting knife, thereby improving the safety of the equipment.

[0046] In some embodiments, Figure 5As shown, the shield 180 is provided with an avoidance hole 181 , through which the tray 200 and the corn can pass.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
