Description

A corn ridge fully covered machine

technical field

The utility model relates to a sowing and tillage machine in agricultural machinery, in particular to a corn ridge full-film mulching machine for field corn ridge full-film mulching planting technology.

Background technique

In recent years, arid areas have vigorously promoted the film-covered sowing technology of crops such as corn, and achieved good economic benefits. With the promotion of ridge-covering seeding technology, related new supporting equipment has been put into production and application. There are mainly small four-wheel tractors with a power of less than 30 horsepower as power ridge mulchers. This type of machine can meet the various procedures of corn ridges and full mulch sowing operations, and achieve the purpose of saving water and harvesting. However, due to the differences in planting agronomy in different regions, the adaptability of the machines cannot meet the actual needs. The representative one is the full-film double-furrow sowing machine that is widely used at present. This machine is mainly suitable for corn planting in rain-fed agricultural areas or slope areas in the central and eastern regions of our province, and cannot meet the needs of ridge planting in the Hexi irrigation area. The problem of planting agronomic differences is mainly manifested in the following: the existing machinery mainly uses wide ridges with a height of about 10 cm and narrow ridges with a height of about 15 cm alternately, and corn is planted at the bottom of the ditch, which is suitable for planting in slope areas. However, this method is not suitable for the cultivation of field corn in the Hexi irrigation area. First, the ridges are low, which can easily lead to flooding and waste water during irrigation; second, when planting at the bottom of the ditch, the soil fertility is poor and the corn yield is low.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of corn ridging and full film covering machine suitable for the planting of field corn, that is, adopting the full film ridge for furrow irrigation planting method, which can cover both the furrows and the ridges with plastic film.

The technical scheme that the utility model solves its technical problem is:

A corn ridge full-covering machine, including a frame, a ridge shovel, a film-laying roller, a depth-limiting wheel, and a film-pressing wheel. Two ridge shovels are arranged in the middle of the front lower end of the frame. Two depth-limiting wheels are provided, a middle soil covering plate is arranged between the two ridging shovels, and one side soil covering plate is respectively arranged on the frame outside the two ridging shovels; each rear of the two ridging shovels Set a conveyor belt, the front end of the conveyor belt is equipped with a driven roller, the rear end is equipped with a driving roller, a scraper is arranged between the driving roller and the driven roller, and a soil chute is arranged behind the driving roller, and the back end of the chute is connected Film-pressing wheel; a bevel gear reducer is arranged in the middle of the frame beam above the middle cover plate, and the bevel gear reducer is connected with the driven drum through a chain and a transmission shaft.

Two lamination rollers are arranged below the rear end of the frame, and the two lamination rollers are staggered front and back.

The side of the ridging shovel is welded with a wing plate, and the shovel body is connected to the side plate of the frame.

The centerlines of the two ridging shovels are 90 centimeters apart.

The rears of the middle soil cover board and the side cover soil boards are provided with spring pressing devices.

The ditching parts of the utility model mainly include two sets of square ridge shovels with wing plates welded on the sides. The shovel body is connected to the side plate of the frame. The function of the device to send soil. The design of the middle soil cover board and the side cover soil boards on both sides mainly plays the role of finishing the soil ridge shape. The two film coating rollers set behind the frame are used to hold the plastic film, and the scraper type lifting device transports the soil to the top , and then spread the film through the soil chute, and the film can be covered on the furrows and ridges, realizing the full coverage of the ground surface, that is, the full film ridge planting, especially suitable for the planting needs of field corn in the Hexi irrigation area.

Detailed ways

Below in conjunction with accompanying drawing, the present invention is described in further detail:

A corn ridge full-covering machine, the overall size of the machine tool is (length x width x height) 208 x 180 x 90 cm, the supporting power is a tractor with a power of 25-35 horsepower, and the width of the film used is 120 cm or 100 cm. As shown in Figure 1, a ridge shovel 3 is respectively connected by bolts on the left and right side plates below the frame 2, and the center lines of the two ridge shovels are 90 centimeters apart. An intermediate soil cover plate 4 is arranged between the two ridging shovels 3, and a side cover soil plate 9 is respectively arranged on the outside of the ridging shovel 3 on both sides of the frame, and hanging lugs are welded on the side cover soil plate 9 and the middle soil cover plate 4, and the cover soil The boards are attached under the rack. Simultaneously, a spring 6 is arranged at the rear of the cover plate. The spring is placed on a section of steel bar, one end of the steel bar is spliced to the cover plate, and the other end passes through the round hole of the frame beam, so that the cover plate can have a certain pre-tightening force through the action of the spring when the cover plate rotates. The rear ends of the two ridge shovels are respectively provided with a conveyor belt 14, the front end of the conveyor belt is equipped with a driven roller 7, and the rear end is equipped with a driving roller 11. The driven roller 7 is connected to the side plate below the frame, and the driven roller 7 and 5 centimeters apart from ridging shovel 3 rear ends. The scraper 8 is fixed on the conveyor belt 14, and the rotation of the driving roller drives the conveyor belt 14 and the driven roller 7 to move, and the scraper conveys the soil to the top. The driving drum 11 rear end is connected with the soil chute 12, and the frame rear end is connected with the pressing film wheel 13. The rear end of the frame 2 is equipped with two lamination rollers 10, and the lamination wheel 13 is positioned behind the lamination rollers 10. A bevel gear reducer 5 is adorned in the beam middle part of the frame 2 above the middle cover plate 4, and the bevel gear reducer 5 is connected with the driven drum 11 by a chain 15 and a transmission shaft 16. During the movement of the drum, part of the soil is mentioned to a high place by the scraper 8, and then is shunted down by the soil slide trough 12, and the film is covered at the position where the ridge side, the furrow, and the plastic film are connected.

When the machine is working, the film must be manually pressed on the ground first. Then connect the output shaft power behind the tractor to drive the bevel gear reducer 5 and the driving drum 11 to move. When the ridging shovel is moving forward, part of the soil can be transported to the rear and upper side through the conveyor belt while ditching. The transmission ratio of the bevel gear reducer 5 is 3:2, the scraper is 5 centimeters high, 18 centimeters wide, and the conveyor belt is 20 centimeters wide, which can ensure uniform and reliable film pressing of the soil. The power is transmitted to the bevel gear reducer 5 through the rear output shaft of the tractor and the cross shaft universal coupling. After the speed is changed, the driving drum 11 is driven to rotate through the chain transmission 15 and the transmission shaft 16, thereby driving the flat belt and the scraper 8 to move. . The side cover plate 9 and the middle cover plate 4 can effectively repair a suitable ridge shape, and by adjusting the spring 6, the pressure of the cover plate can be appropriately changed to further repair the ridge shape. Laminating roller 10 is connected at the rear bottom of frame, and two laminating rollers 10 are staggered mutually before and after. The mulch is placed on the film-covering roller 10, and 2 widths are used to be 1.2 meters or 1 meter of mulch. As the unit moves forward, the plastic film is spread in the furrow, and at the same time, the soil lifted to a high place falls through the soil chute 12 and is pressed on the plastic film. Membrane effect. The depth of the ditch can be adjusted by the depth gauge wheel 1.
