Description

Technical Field

[0001] The utility model belongs to the technical field of corn silage harvesting, and in particular relates to a high-ground-clearance double-row corn silage machine. Background Art

[0002] Corn is an important food crop. In order to increase its yield, we not only need high-quality corn seeds, but also a reasonable planting density.

[0003] Existing corn seeds are obtained through hybrid seed production. During the hybrid seed production process, male corn and multiple rows of female corn are planted alternately to pollinate the female corn. In order to ensure the purity of the corn seeds, the male corn needs to be harvested for silage after pollination. This can not only reduce the consumption of nutrients in the land, but also improve the ventilation and light conditions of the female corn, which is beneficial to improving the yield and quality of the corn seeds of the female corn.

[0004] When planting corn, many farmlands adopt a dense planting method, and select rows of corn for silage harvesting before flowering to ensure the density of planting. At the same time, the silage harvested corn can be made into feed to increase profits.

[0005] At present, whether it is silage harvesting of male corn during hybrid seed production, or selective silage harvesting of corn during dense planting, the harvesting is mainly done by corn silage machines. The harvesting efficiency is relatively low and it is easy to damage the normally growing corn. Utility Model Content

For the convenience of description, only the parts related to the utility model are shown in the figure.

[0033] Depend on Figures 1 to 9It can be seen that the high-ground clearance double-row corn silage machine of the utility model includes a frame 10, on which a cab 20, a cargo box 30a, a front wheel mechanism 40a, a rear wheel mechanism 40b and an engine 60 are installed; the front wheel mechanism 40a and the rear wheel mechanism 40b respectively include a drive axle 41, wheels 42 respectively arranged at the two ends of the drive axle 41, high-ground clearance bridge legs 43 are respectively arranged between the two ends of the drive axle 41 and the wheels 42 on the corresponding sides, an upper power transmission box 44 is arranged between the end of the drive axle 41 and the upper end of the high-ground clearance bridge leg 43, and a lower power transmission box 45 is arranged between the lower end of the high-ground clearance bridge leg 43 and the wheel 42; the engine 60 is drivingly connected to the input shaft of the drive axle 41 of the rear wheel mechanism 40b, and a rear drive axle box 411 of the drive axle 41 of the rear wheel mechanism 40b is provided at the side thereof The front drive force component drive box 50b is connected to the differential bevel gear transmission inside the rear drive axle box 411, and a transmission connecting rod 90 is provided between the output shaft of the front drive force component drive box 50b and the input shaft of the front drive axle box 412 of the drive axle 41 of the front wheel mechanism 40a; it also includes a cutting table device 70 respectively installed on the left and right sides of the front part of the frame 10, and the cutting table device 70 includes a mounting frame 71 slidably installed on the frame 10 along the left and right directions, a translation drive mechanism 72 for driving the mounting frame 71 to slide, a cutting table bracket 73 slidably installed on the mounting frame 71 along the vertical direction, a lifting drive mechanism 74 for driving the cutting table bracket 73 to slide, a cutting table mechanism 75 fixed on the cutting table bracket 73, a crushing and throwing mechanism 76 connected to the output port of the cutting table mechanism 75, and a scattering pipe 77 connected to the crushing and throwing mechanism 76.

[0034] For ease of understanding, the use of high-clearance double-row corn silage machine is explained as follows, taking silage harvesting of parent corn as an example:

[0035] During the hybrid seed production process, when the male parent corn is harvested for silage, the positions of the two header devices 70 are adjusted so that the two header devices 70 correspond to the two rows of male parent corn, and then the lifting drive mechanism 74 drives the header mechanism 75 and the crushing and throwing mechanism 76 connected to the output port of the header mechanism 75 to fall. As the high-ground clearance double-row corn silage machine moves forward, the header mechanism 75 cuts down the male parent corn and transports it to the crushing and throwing mechanism 76, which is crushed by the crushing and throwing mechanism 76 and then transported to the cargo box 30a through the throwing pipe 77. The two rows of male parent corn can be harvested for silage at the same time, which improves the corn silage harvesting efficiency. In addition, the positions of the two header devices 70 can be adjusted, which can be suitable for the silage harvesting of male parent corn with different spacings. Under the support of the wheels 42 and the high-ground clearance bridge legs 43, the frame 10 and the cab 20, the cargo box 30a and the engine 60 arranged on the frame 10 are all across the rows above the female parent corn, and the female parent corn will not be damaged when the corn is harvested for silage.

[0036] The engine 60 is connected to the input shaft of the rear drive axle box 411 of the drive axle 41 of the rear wheel mechanism 40b, and can provide driving force for the rear wheel mechanism 40b; at the same time, a front drive component drive box 50b is provided at the side of the rear drive axle box 411 of the drive axle 41 of the rear wheel mechanism 40b, which is connected to the driven bevel gear inside the rear drive axle box 411, and a transmission connecting rod 90 is provided between the output shaft of the front drive component drive box 50b and the input shaft of the front drive axle box 412 of the drive axle 41 of the front wheel mechanism 40a. The rear wheel mechanism 40b can also provide power for the front wheel mechanism 40a to form a four-wheel drive structure, and can enable the rear wheel mechanism 40b and the front wheel mechanism 40a to maintain a synchronous speed, so as to facilitate the stable walking of the high-ground clearance double-row corn silage machine in the corn field.

[0037] The high-ground clearance double-row corn silage machine of the utility model is driven by a four-wheel drive structure formed by a rear wheel mechanism 40b and a front wheel mechanism 40a, and can stably move in a corn field, and can simultaneously harvest two rows of corn for silage, thereby improving harvesting efficiency and solving the problems of low corn silage harvesting efficiency and easy damage to normally growing corn.

[0038] When harvesting densely planted corn for silage, the positions of the two header devices 70 are adjusted so that the two header devices 70 correspond to the two selected rows of corn that need to be harvested for silage, so that two rows of corn can be harvested for silage at the same time without damaging the normally growing corn.

Usually, the rotation driving mechanism is a cutter hydraulic motor; the feeding guide roller 753 includes a feeding roller shaft arranged vertically, and a plurality of feeding paddles arranged at circumferential intervals along the feeding roller shaft and extending along the rotation axis direction of the feeding roller shaft, and the feeding paddles are arranged in a tooth shape away from the outer side of the feeding roller shaft; specifically, the structure of the circular knife disc 752 is a well-known technology, and its specific structure is not repeated here. When harvesting corn for silage, the disc cutter on the circular knife disc 752 cuts the corn stalks at the feeding entrance, and the disc teeth on the circular knife disc 752 transport the cut corn stalks to the inside of the crushing device 76. Since the feeding guide roller 753 is rotatably installed at the side of the circular knife disc 752, it can assist in the transportation of corn stalks and avoid the cut corn stalks from being blocked at the feeding entrance.

[0040] Typically, the distance between the outer edge of the feeding paddle and the rotating shaft of the feeding roller decreases gradually from top to bottom, making it easier to use corn stalks of different thicknesses.
