Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a corn harvester. Background Art

[0002] A corn harvester is an agricultural machine that mechanically removes mature corn ears, stacks them, and returns the stalks to the field all at once. The process involves harvesting ears while the corn is still growing (known as standing stalk picking). The picking rollers and picking plates break the stalks of the ears. Due to the height difference between the inner and outer picking rollers, the ears fall into an ear box. Once the boxes are full, the ears are unpacked and stacked. A high-speed cutter severs the stalks at the base, which are then shredded into 3-5 cm long pieces by a comminution mechanism. After shredding, the stalks fall naturally to the ground. The ears are then transported to the field, peeled using a husker, and air-dried before being threshed.

[0003] The corn harvesters currently in use often encounter completely dry corn stalks when pulling corn out of the ground. These corn stalks often break when being pulled out of the ground by the harvester, that is, the bottom of the corn stalk is still planted in the soil, resulting in the corn stalk being unable to be completely broken, affecting the backfill effect.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0037] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0038] A corn harvester provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example

[0039] Combine Figure 1-Figure 7 As shown, the utility model provides a corn harvester, including a material collecting mechanism 100, a pulling-down mechanism 200, a crushing mechanism 300 and a tilling mechanism 400. The material collecting mechanism 100 includes a tractor 110, an integrated frame 120 connected to the front of the tractor 110, two shells 130 connected to the integrated frame 120, a short shaft 140 and a long shaft 150 movably mounted inside the shell 130, two sprockets 160 respectively sleeved on the bottom ends of the short shaft 140 and the bottom ends of the long shaft 150, a chain 170 connected between the two sprockets 160, a rubber sleeve 180 sleeved on the outside of the chain 170, a motor 190 with an output shaft connected to the top end of the long shaft 150, and a body of the motor 190 connected to the top of the shell 130;

[0040] The pull-down mechanism 200 includes a bevel gear 1 210 sleeved on the bottom end of the long shaft 150, a bevel gear 220 meshing with the bottom of the bevel gear 1 210, a horizontal shaft 230 extending transversely through the bevel gear 220 and movably mounted within the housing 130, and a spiral roller 240 sleeved on the outside of the horizontal shaft 230. The spiral roller 240 is located on one side of the bevel gear 220.

[0041] The crushing mechanism 300 includes a knife sleeve 310 installed in one housing 130, two electric push rods 320 installed in the other housing 130, and a cutter 330 connected between the two electric push rods 320. The cutter 330 is movably connected to the knife sleeve 310, and the two electric push rods 320 are connected in series.

[0042] The tillage mechanism 400 includes a second motor 410 connected to the rear of the tractor 110, a hydraulic cylinder 420 connected to the output shaft of the second motor 410, a connecting rod 430 connected to the movable end of the hydraulic cylinder 420, a trailer 440 connected to the outer end of the connecting rod 430, and a harrow hook 450 connected to the top of the trailer 440.

[0043] Furthermore, the two shells 130 are symmetrically arranged with a distance between them. The distance is set to ensure that the corn stalks can smoothly enter between the two shells 130 and ensure that the corn can be plucked.

[0044] Furthermore, the short axis 140 and the long axis 150 inside the shell 130 are vertically located in the same horizontal plane, and the short axis 140 and the long axis 150 are both set to be T-shaped. With this layout design, the chain 160 and the rubber sleeve 180 are placed horizontally, ensuring that the corn stalks can enter the deep spacing and ensure that the corn on the corn stalks can be plucked off.

[0045] Furthermore, a baffle 700 is connected between the two shells 130 , and the baffle 700 is in contact with the outer wall of the feeding channel 510 . The baffle 700 is provided to prevent the corn stalks from flowing out from between the two shells 130 without being processed.

[0046] Furthermore, the baffle 700 is composed of a door frame and a baffle, and the bottom of the baffle is in contact with the top of the two shells 130. With this structural design, while preventing corn stalks from leaving between the two shells 130, the corn can pass smoothly from the bottom of the baffle.

[0047] Furthermore, a collecting bag 800 is installed on the integrated frame 120, and the collecting bag 800 is located between the tractor 110 and the feeding channel 510. The setting of the collecting bag 800 can collect corns in a unified manner, thereby improving the comfort of using the device. Example

[0048] Combine Figure 1 and Figure 8 As shown, on the basis of Example 1, a peeling mechanism 500 is provided on the top of the integrated frame 120, and the peeling mechanism 500 includes a feeding channel 510 connected to the integrated frame 120, two rotating shafts 520 movably installed inside the feeding channel 510, a motor three 530 connected between the feeding channel 510 and the rotating shaft 520, and a plurality of rubber strips 540 surrounded on the outside of the rotating shaft 520. The two motors three 530 are connected in series. When the corn enters the feeding channel 510, the rubber strips 540 connected to the rotating shaft 520 will continuously hit the outer skin of the corn, thereby achieving the purpose of peeling. Example

[0049] Combine Figure 1-2 As shown, in the above embodiment, a cover plate 600 is installed on the top of the inner cavity of the shell 130, the bottom of the cover plate 600 is in contact with the top of the rubber sleeve 180, and the short axis 140 and the long axis 150 are both vertical and movable through the cover plate 600. The cover plate 600 can prevent the plucked corn from falling between the two sprockets 160.

[0050] The working principle and use process of the present invention are as follows: the staff sits on the tractor 110 to operate the machine, and then when the machine harvests corn, the corn stalks are made to enter the inner space, and then the two motors 190 are started at the same time. Under mechanical transmission, the two chains 170 rotate at the same time, and then the rubber sleeve 180 makes the corn stalks enter the deep space, and at the same time, the bevel gear 1 210 sleeved on the bottom end of the long shaft 150 affects the rotation of the bevel gear 220, and then the bevel gear 220 drives the horizontal shaft 230 and the spiral roller 240 to rotate, and the two spiral rollers 240 cooperate to squeeze the corn stalks down, and then the corn on the corn stalks is smoothed off between the two rubber sleeves 180, and then only when the corn stalks pass between the knife sleeve 310 and the cutter 330, the two electric push rods 32 0 frequently and efficiently moves the cutter 330, thereby achieving the cutting of the corn stalks. At the same time, the removed corn follows the movable rubber sleeve 180 to the inside of the feeding channel 510, and then the motor 3 530 is started, and then the shaft 520 rotates with multiple rubber strips 540. The rubber strips 540 hit the corn husks to peel off the corn husks. During this process, the motor 2 410 drives the hydraulic cylinder 420 to rotate clockwise and counterclockwise. The hydraulic cylinder 420 then swings the trailer 440 and the rake hook 450 through the connecting rod 430. Then the movable end of the hydraulic cylinder 420 extends, and the rake hook 450 indirectly inserts into the ground, thereby turning the soil, turning out the broken corn stalks, and also disrupting the broken corn stalks, improving the return to the field effect.

[0051] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
