Description

Technical Field

[0001] The invention discloses a corn plot harvester suitable for strip-shaped composite planting of corn and cotton, belonging to the technical field of agricultural machinery. Background Art

[0002] Strip composite planting refers to the alternating planting of two crops in the field, which can meet the needs of both crops without blocking the light. Corn-cotton strip composite planting is to plant 2-4 rows of cotton between two rows of corn. The corn plant spacing in strip composite planting is different from that of ordinary corn planting. The plant spacing of ordinary corn planting is 20-25cm, but the plant spacing of corn in strip composite planting is about 12cm, and the corn planting density is doubled.

[0003] The cell in this application refers to the division of farmland into smaller plots, which are mainly used for agricultural experiments, such as experiments on seeds and planting techniques. Cell planting is not suitable for large agricultural machinery, and only small machinery can be used. Small operating machinery usually moves forward and turns by hand. When harvesting corn with high-density composite planting, the corn stalks are clamped by the ear-picking rollers and bent backwards. At this time, due to the high plant density, the front end of the harvester is required to have a high ground clearance, otherwise the harvester cannot move forward normally.

[0004] In addition, when harvesting corn planted in the community, it is tiring to operate for a long time. Although some small machines have added seats, they are not easy to adjust and there are many inconveniences when using them. Utility Model Content

DETAILED DESCRIPTION

[0025] Figures 1 to 5 This is the best embodiment of the corn plot harvester suitable for corn and cotton strip composite planting. Figures 1 to 6 The utility model is further described.

[0026] Example 1

[0027] Reference Figure 1-3The corn plot harvester suitable for strip-shaped composite planting of corn and cotton includes a harvester body, a front support wheel 8, a rear support wheel 9 and a driver's seat 11. An armrest 12 is provided at the rear of the harvester body. The front support wheel 8 is arranged at the front end of the harvester body. A rear support beam 10 is provided at the rear side of the harvester body. The rear support beam 10 is rotatably arranged at the rear side of the harvester body. The rear support wheel 9 and the driver's seat 11 are both arranged on the rear support beam 10.

[0028] The harvester body includes a frame 1, an engine 2, an ear picking roller 4, a collecting box 5, a fork wheel 6 and a crushing knife 7. Wheels 3 are provided on both sides of the frame 1. The engine 2 is arranged on the upper side of the frame 1. Two ear picking rollers 4 are rotatably arranged in front of the engine 2. The fork wheel 6 is arranged in front of the ear picking roller 4. A protective cover 29 is provided on the outer side of the fork wheel 6. The crushing knife 7 is arranged on the lower side of the ear picking roller 4. The wheels 3, the ear picking roller 4, the fork wheel 6 and the crushing knife 7 are connected to the engine 2 through a transmission mechanism. The transmission mechanism in this embodiment is a pulley and a belt.

[0029] The collecting box 5 is arranged on one side of an ear picking roller 4, an ear picking baffle 15 is arranged on the upper side of the other ear picking roller 4, a front guide rod 14 is arranged on the front side of the ear picking roller 4, an upper guide rod 16 is arranged on the upper side of the ear picking roller 4, and a rear baffle 17 is arranged on the rear side of the ear picking roller 4. A vertical rod 19 is fixed on the rear baffle 17, and at least two rear baffles 18 are arranged on the vertical rod 19. The height of the rear baffle 18 is adjustable on the vertical rod 19. Side baffles 13 are arranged on both sides of the front end of the frame 1, and the crushing knife 7 is arranged between the side baffles 13 on both sides. The side baffles 13 block the debris generated by the crushing knife 7 when crushing the straw from spreading to both sides, thereby reducing the loss of insect eggs to other interplanted crops.

[0030] In this embodiment, two rear support wheels 9 are arranged at intervals on the rear support beam 10, and the driver's seat fixing bracket is arranged between the two rear support wheels 9. The two sides of the rear support wheel 9 on the front side of the driver's seat fixing bracket are rotatably connected with footrests 20. The operator's feet are placed on the footrests 20, which is conducive to operating the handrail 12 for steering and is also more comfortable. Since the rear support wheel 9 contacts the ground, the rear support beam 10 will not swing significantly during the movement of the wheel 3.

[0031] A rear wheel fixing seat 21 is slidably arranged on the rear support beam 10, and the rear support wheel 9 is rotatably arranged at the lower part of the rear wheel fixing seat 21, so that the position of the rear support wheel 9 on the rear support beam 10 can be submitted. In addition, the driver's seat 11 is arranged on the rear support beam 10 through a driver's seat fixing bracket, and the position of the driver's seat fixing bracket on the rear support beam 10 is adjustable.

[0032] The driver's seat fixing bracket includes a driver's seat horizontal position adjustment slide 22, a lower bracket 23 and an upper bracket 24. The driver's seat horizontal position adjustment slide 22 is slidably set on the rear support beam 10, the lower bracket 23 is fixed on the upper side of the driver's seat horizontal position adjustment slide 22, the upper bracket 24 is height-adjustably connected to the upper part of the lower bracket 23, and the driver's seat 11 is fixed to the upper end of the upper bracket 24.

[0033] See also Figure 4 The rear support beam 10 is detachably connected to the harvester body through a pin shaft 25. The rear support beam 10 can be removed in a plot with a small operating space, and the operator can stand on the ground and operate through the armrest 12, or sit on the driver's seat 11 after connecting the rear support beam 10, which is very flexible to use.

[0034] See also Figure 5 The front supporting wheel 8 is connected to the harvester body through a height adjustment mechanism. Specifically, the height adjustment mechanism includes a front wheel height adjustment rod 26. The front wheel height adjustment rod 26 is arranged on the upper side of the front supporting wheel 8. A front wheel adjustment seat is provided at the front end of the harvester body. The front wheel height adjustment rod 26 is height-adjustably connected to the front wheel adjustment seat.

[0035] The front wheel adjustment seat includes a front wheel adjustment cross bar 27 and a front wheel adjustment slide 28. The front wheel adjustment cross bar 27 is horizontally fixed at the front end of the harvester body, and the front wheel adjustment cross bar 27 is perpendicular to the forward direction of the harvester body. The front wheel adjustment slide 28 is slidably set on the front wheel adjustment cross bar 27, and the front wheel height adjustment rod 26 is height-adjustably connected to the front wheel adjustment slide 28.

[0036] Working process: The operator sits on the driver's seat 11 and controls the forward direction through the armrest 12. A lever is provided between the two armrests 12 to control the forward speed. The engine 2 drives the wheel 3 to rotate through the pulley and the belt, driving the harvester body forward. During the forward movement, the corn stalks are pulled between the two ear-picking rollers 4 by the fork wheel 6. The ear-picking rollers 4 rotate relative to each other to separate the corn ears from the stalks and put the corn ears into the collection box 5. The corn stalks continue to move downward and are crushed by the crushing knife 7 and returned to the field. When the number of corn ears in the collection box 5 reaches a certain amount, the control handle on the armrest 12 (not shown in the figure) is used to pull open the door panel at the bottom of the collection box 5, so that the corn ears in the collection box 5 are placed on the ground, and then the corn ears are manually collected.

[0037] Example 2

[0038] See also Figure 6 In this embodiment, only one rear support wheel 9 is arranged on the rear support beam 10, and the rear support wheel 9 is arranged in front of the driver's seat 11. Since the rear support wheel 9 only needs to bear the weight of one operator, one rear support wheel 9 can also meet the requirements. In this embodiment, both sides of the rear support wheel 9 are also connected to footrests 20.

[0039] The corn plot harvester suitable for strip-shaped composite planting of corn and cotton can also be suitable for corn and soybean strip-shaped composite planting test fields.
