Technical Field

The invention belongs to the technical field of corn protective farming mechanization, and particularly relates to a straw row-returning treatment device for covering the ground surface before planting.

Background

The corn protective farming area of China is continuously increased year by year, but compared with developed countries in Europe and America, the corn protective farming area has the problem of low operation quality, the coverage of the straws on the ground surface is too low, if the whole amount of the straws are returned to the field and no-tillage seeding machines are difficult to operate, the emergence rate is seriously influenced, and most of the surplus straws are subjected to incineration treatment, so the environment is seriously polluted. Meanwhile, the corn planting and farming modes are backward. The development and utilization of high strength, wind erosion, water erosion and the use of a large amount of chemical fertilizers cause soil hardening, and the organic matters in the black land are reduced to below 2 percent from 6 to 8 percent during the reclamation. The water loss and soil erosion are serious, and the protection mode of the black land is lacked. Aiming at the situation, the straw strip collecting machine provided by the invention can solve the problems. The invention ensures that a clean seeding seedbed is cleaned under the condition of returning the whole straws to the field, so that the subsequent no-tillage seeding can keep higher emergence rate, thereby ensuring stable yield and high yield, returning the whole straws to the field, solving the problem that the land can not be planted without burning, returning the whole straws to the field and really realizing the most reasonable way of straw utilization. The emergence of the invention will certainly greatly promote the rapid development of protective farming.

Disclosure of Invention

The invention aims to provide a device capable of collecting broken straws in a field according to the requirements of a planting mode.

The invention is realized by adopting the following technical scheme: 1. the machine frame of the post-positioned four-row straw gathering machine is hung at the back of a tractor in three-point suspension mode, the suspension is located at the highest floating position, the left support arm and the right support arm are respectively installed on the machine frame, the outer support is installed on the two sides of the support, the whole lifting of the mechanism is realized by the adjustment of the tractor suspension, the outer support is connected with the support through the extension hydraulic cylinder, and the extension hydraulic cylinder is used for lifting the outer support. And after the installation is finished, the frame is connected with the support arm by using a limiting spring. 2 the directions of the finger plates on one side are consistent, and the finger plates on the other side form an included angle with the finger plates. 3. A pair of finger plates is arranged on each support arm, and the included angle of the two finger plates is the width of the seedling belt cleaned during operation. 4. The included angle of each group of finger plates is adjusted through the adjuster, and the finger plates are used for different operation requirements. 5. The hydraulic cylinder is extended and contracted in the transportation process, the outer bracket and the rack are in a vertical state, and the hydraulic cylinder is extended and falls down in the operation process.

The straw returning and seeding machine is reasonable and compact in structure and convenient to install and use, straw is returned before being sowed under the condition that the straw covers the ground, the full straw returning is realized, the seedbed is cleaned, and the effects of preserving soil moisture, improving ground temperature and improving the rate of emergence are obvious.

Drawings

The invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic front view of the present invention;

in the figure: 1. the device comprises a frame, 2 parts of an upper suspension, 3 parts of a lower suspension, 4 parts of an extending hydraulic cylinder, 5 parts of a limiting spring, 6 parts of an outer support, 7 parts of a support arm, 8 parts of an adjuster, 9 parts of a finger plate and 10 parts of a U-shaped clamp.

Detailed description of the preferred embodiments

As shown in fig. 1, the present invention comprises a frame 1 connected to a tractor by an upper suspension 2 and a lower suspension 3. A support arm 7 and a limiting spring 5 are arranged right behind the frame 1, and an outer support 6 and an extension hydraulic cylinder 4 are arranged on two sides of the frame 1. A support arm 7 is respectively arranged on the frame 1 and the outer support 6 through a U-shaped clamp 10, and a finger disc 9 and an adjuster 8 are arranged at the other end of the support arm 7. During transportation, the outer support 6 is vertical to the frame 1, and during operation, the outer support 6 is parallel to the frame 1. During operation, the advancing direction and speed of the invention are consistent with those of a tractor, the finger disc 9 rubs with the ground surface covered by the straws, so that the finger disc 9 rotates, and the linear speed of the rotation is consistent with the advancing speed of the tractor. Four support arms 7 are respectively provided with four groups of eight finger plates 9 during operation, an included angle is formed between each group of finger plates 9, the distance of the circle center of each group of finger plates 9 is the width of the seedling belt required by operation, the width is adjusted by an adjuster 8, and the distance between each support arm 7 is determined by the installation position of each U-shaped card 10. During the operation, the finger plates 9 contact the straws and gather strips outside the finger plates 9, so that a clean seedling zone without straws is formed between each group of finger plates 9 for sowing.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and implementation effect, and unnecessary technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
