Description

Corn harvester

The technical field is as follows:

the utility model belongs to the technical field of agricultural machine, specifically speaking especially relates to a maize picker.

Background art:

in agricultural production, harvesting of corn is a high-intensity labor, because the height of corn is high and the leaves are thorny, if the corn is harvested in a corn field manually, the skin of the human skin can be scratched by the corn leaves, the high corn causes poor ventilation in the field, the temperature is high, and the work in the field is very uncomfortable; in addition, a lot of dust falls on leaf surfaces and straws in the growth process of the corns, and some dust contains viruses and the like, so that skin allergy, pruritus and even pathogenicity can be caused when the corns are operated in the field.

The basic working principle of the existing corn harvesting machine is as follows: the whole plant of corn including straw and corn cob is guided into a narrow gap, and two metal roller pairs on two sides bring down the corn straw, but the corn cob is too thick to pass through the narrow gap, thereby passively pulling off from the straw, and the corn cob is collected by a collecting device.

The metal pair roller of the machine has strong peeling capacity, can not only take corn straws down, but also peel corn kernels off corn cobs, and the corn kernels fall into the ground to cause certain loss, waste partial grains, need to be picked up manually, and cause great trouble to farmers.

The invention content is as follows:

the to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a maize picker, its first guard plate and second guard plate are the metal sheet, have guaranteed life, and first rubber and second rubber are elastic, have guaranteed that the maize has just hit when getting off and has hit on the rubber, do not harm the corn-on-cob, have guaranteed the integrality of corn-on-cob.

In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:

the utility model provides a corn harvester, includes frame, maize collecting box, first spike of plucking axle and second spike of plucking axle, and one side of frame is located to the maize collecting box, be equipped with first guard plate and second guard plate in the frame, first guard plate is located one side of first spike of plucking axle, and one side of spike of plucking axle is located to the second guard plate, distance between first guard plate and the second guard plate is a.

Preferably, the first protection plate is provided with first rubber, and the second protection plate is provided with second rubber.

Preferably, the value range of the distance a between the first protection plate and the second protection plate is more than 3 centimeters and less than 7 centimeters.

Preferably, the first protection plate is an L-shaped plate.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model can lead the corn cobs to be smashed on the first rubber and/or the second rubber in the extrusion process by adding the first rubber on the first protection plate and the second rubber on the second protection plate, and the corn cobs can not be damaged but directly fall into the corn collection box after being peeled off because the first rubber and the second rubber have elasticity and are softer;

2. the first protection plate and the second protection plate are metal plates, so that the service life is guaranteed, the first rubber and the second rubber are elastic, the corn is guaranteed to just hit the rubber when hitting down, the corn cobs are not damaged, and the integrity of the corn cobs is guaranteed.

Description of the drawings:

fig. 1 is a front view of the present invention;

FIG. 2 is a front view of the first guard and the second guard of the present invention;

fig. 3 is a schematic structural diagram of the first protection plate and the second protection plate of the present invention.

In the figure: 1. a corn collection box; 2. first picking cob; 3. secondly, picking the cob; 4. a first guard plate; 5. a first rubber; 6. a second rubber; 7. a second guard plate; 8. a fixing plate; 9. a frame; 10. a cutting knife; 11. and (5) traveling wheels.

The specific implementation mode is as follows:

the present invention will be further described with reference to the following specific embodiments and accompanying drawings.

Example 1:

as shown in fig. 1-3, a corn harvester comprises a frame 9, a corn collecting box 1, a first spike picking shaft 2 and a second spike picking shaft 3, wherein the corn collecting box 1 is arranged on one side of the frame 9, a cutting knife 10 and a travelling wheel 11 are arranged at the lower end of the frame 9, a first protection plate 4 and a second protection plate 7 are arranged on the frame 9, the second protection plate 7 is fixedly arranged on the frame 9 through a fixing plate 8, the first protection plate 4 is arranged on the frame 9 on one side of the first spike picking shaft 2, the second protection plate 7 is arranged above the second spike picking shaft 3, and the distance between the first protection plate 4 and the second protection plate 7 is a; the first protection plate 4 is bolted or welded on the frame 9, and the second protection plate 7 is bolted or welded on the fixing plate 8.

Example 2:

a corn harvester is characterized in that first rubber 5 is arranged at the upper end of a first protection plate 4, and second rubber 6 is arranged at the upper end of a second protection plate 7; the first rubber 5 is adhered to the first protection plate 4 through bolts or strong adhesion, and the second rubber 6 is adhered to the second protection plate 7 through bolts or strong adhesion.

The value range of the distance a between the first protection plate 4 and the second protection plate 7 is more than 3 centimeters and less than 7 centimeters. The value range of a is not less than the diameter of the corn stalks, so that the corn stalks can pass through the gap, and the value range of a is not greater than the diameter of the corn cobs, so that the corn cobs are prevented from entering between the first ear picking shaft 2 and the second ear picking shaft 3 and not smoothly falling into the corn collection box 1.

The first protection plate 4 is an L-shaped plate. The other portions are the same as in example 1.

The utility model discloses the principle of during operation does:

and starting the walking tractor, sequentially transmitting power to the first ear picking shaft 2, the second ear picking shaft 3 and the cutter 10 through the gearbox, and cutting the corn straws by the cutter 10 in a 360-degree rotating manner.

When the corn harvester works, the first ear picking shaft 2 and the second ear picking shaft 3 rotate relatively, one corn plant is pulled in through the poking rod, the corn harvester continues to advance slowly, the reel rotates to pull the corn plant further into the middle of the first ear picking shaft 2 and the second ear picking shaft 3, the cutting knife 10 works to cut the corn plant simultaneously, the corn plant is dragged downwards by the cutting knife 10 to be cut continuously, corn cobs on the corn plant are squeezed by the gaps between the first ear picking shaft 2 and the second ear picking shaft 3, and the squeezed corn cobs slide down to the corn collecting box 1 along the first ear picking shaft 2 at the lower end because the gap between the first ear picking shaft 2 and the second ear picking shaft 3 is smaller than the corn cobs; as the rainy season is more in this year, most of cobs in the cobs are rotted seriously, if the cobs are extruded by gaps between the first harder ear picking shafts 2 and the second harder ear picking shafts 3, the cobs are crushed easily, and the corn kernels fall to the ground, the cobs can be smashed on the first rubber 5 and/or the second rubber 6 in the extruding process by adding the first rubber 5 with elasticity on the first protection plate 4 and the second rubber 6 with elasticity on the second protection plate 7, and the cobs can not be damaged and fall into the corn collection box 1 after being directly peeled off because the first rubber 5 and the second rubber 6 have elasticity and are softer.
