Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of corn conservation tillage mechanization, and relates to a device for returning straw on the ground surface to a row before or at the time of planting. BACKGROUND

[0002] In recent years, the area of corn planted by using the conservation tillage technology in China has been continuously increasing, but compared with some developed countries, the conservation tillage technology still has certain limitations, the straw covering amount cannot exceed 30%, otherwise the no-tillage seeding machine cannot work normally, which seriously affects the operation quality. In view of the above situation, the straw returning machine provided by the present application can solve the above problems. The present application ensures that a clean seeding seedbed is cleaned up under the condition that the straw is fully covered and returned to the field, so that the subsequent no-tillage seeding can maintain a high emergence rate, thereby ensuring stable yield and high yield, solving the problem that the field cannot be planted without processing the straw, achieving full straw return to the field, and truly realizing the most reasonable way of comprehensive utilization of straw. The present application will greatly promote the rapid development of conservation tillage. SUMMARY

[0003] The present application aims to provide a device capable of returning the crushed straw in the field to a row according to the planting mode requirements.

[0004] The technical scheme adopted by the present application is as follows: a push-pressing type double-row straw returning machine, comprising a raking disc, a raking disc bearing seat (right), a lower machine frame, a steel pipe (compression spring shaft), an upper machine frame, a main machine frame, a hinged shaft (main machine frame), a lifting oil cylinder, a compression spring shaft, a hinged shaft (oil cylinder), a compression spring, a hinged shaft (compression spring shaft), a front support, a raking disc bearing seat (left), a right-angle clamp, and a support plate, characterized in that the raking disc is 4, and is installed at the front of a tractor, and every 2 raking discs are combined into a working group.

[0005] Further, the left and right two groups of raking discs are symmetrically distributed with the plane formed by the center line of the lifting oil cylinder and the center line of the compression spring shaft as the symmetric plane.

[0006] Further, the two raking discs distributed in the inside of the machine tool are arranged in front and in parallel, and the two raking discs distributed outside the machine tool are arranged behind and in parallel.

[0007] The present application has the advantages of reasonable structure, compactness, convenient installation and use, and the like. The present application is used for crushing straw covering land, and the straw returning treatment is performed in autumn. The front returning machine and the no-tillage seeding machine are simultaneously installed on the same tractor during seeding in spring, and the straw returning and seeding operations are completed once. The two modes both realize full straw return to the field, and clean up the seedbed, which has obvious effects on soil conservation, improvement of ground temperature, and improvement of emergence rate.

[0011] As Figure 1As shown, the application comprises a main frame 6, which is connected with the front frame of the tractor by self-made connecting pieces (standard pieces cannot be formed due to different tractor manufacturers and models), and is connected with the upper frame 5 through a hinged shaft (main frame) 7, the bottom end of the lifting oil cylinder 8 is connected with the main frame through a hinged shaft (oil cylinder) 10, the end of the hydraulic rod is connected with the upper frame through a hinged shaft (compression spring shaft) 12, the oil inlet and outlet of the lifting oil cylinder is connected with the hydraulic system of the tractor through a hydraulic oil pipe, the lower frame 3 is connected with the main frame through a hinged shaft (main frame) 7, the compression spring shaft 9 is sleeved into the compression spring 11 and is connected with the upper frame 5 and the lower frame 3 through a hinged shaft (main frame) 7 and a steel pipe (compression spring shaft) 4 respectively, the lifting oil cylinder 8 is placed at the bottommost position, the position of the compression spring 11 is adjusted so that the lower frame 3 is in a horizontal working position, the two front supports 13 are fixed on the two sides of the front arm of the lower frame 3 through right-angle clamps 15, and the adjusting pin shafts on the front supports 13 are directed upward, the distance from the central vertical plane is adjusted so that the two front supports 13 are symmetrical left and right, the bearing seat (left) 14 and the bearing seat (right) 2 are installed along the forward direction of the returning machine, and the adjusting pin shafts on the bearing seat (left) 14 and the bearing seat (right) 2 are directed upward, the front supports 13 and the bearing seat (left) 14 or the bearing seat (right) 2 are connected through the installation of the support plate 16, the bearing seat (left) 14 or the bearing seat (right) 2 and the lower frame 3 are connected, the straw raking disc 1 is installed, the working angle of the straw raking disc 1 is determined by adjusting the installation hole position of the support plate 16, and the straw returning width is determined by adjusting the front supports 13. During transportation, the lifting oil cylinder 8 is pushed to the high point so that the straw raking disc 1 of the returning machine is away from the ground. During operation, the lifting oil cylinder 8 is placed at the low point to ensure that the straw raking disc 1 reaches the working contact position with the ground. The power of the application belongs to the driven type, and the application itself is driven by the power of the tractor. According to the planting requirements, the width of the seedbed and the width after the straw returning can be controlled by the position of the front supports 13 and the hole position of the support plate 16. The wheels of the tractor walk in adjacent narrow rows, the two groups of straw raking discs 1 work in the inner wide rows of the two narrow rows, and the two groups of straw raking discs 1 work on the side close to the narrow row on the outside of the two narrow rows. During operation, the elastic tines on the straw raking discs 1 clean and concentrate the straw in the narrow rows, thereby completing the operation.

[0012] Finally, it is to be noted that the above technical features constitute the best embodiment of the application, which has strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet different requirements.
