Description

A double-ridge rotary tillage and ridging machine

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to a double-ridge rotary tillage, ridging and pressing integrated machine.

Background Art

At present, whether it is planting vegetables or medicinal herbs, ridge planting is basically adopted. The traditional ridge-making method is to directly use the plow blade to turn the furrow into a ridge, or to directly modify the rear side of the rotary tiller into a forming board and use several boards to scrape out a trapezoidal ridge. The ridge shape made by this traditional ridge-making method is not standard, and the ridges are very loose and easy to collapse. After a rain, the actual ridge height will be reduced a lot, and the water, fertilizer and moisture retention are very poor. At the same time, the ridge surface is uneven, the sowing and planting depths are inconsistent, and the growth of crops will also be affected.

In order to solve the above problems, the applicant has developed a traction-type ridging and pressing integrated machine and submitted a patent application (application number is 2023222422452), which includes a soil crushing and ridging mechanism, a pressing roller and a gearbox; the soil crushing and ridging mechanism includes a frame and a soil crushing and ridging knife installed in the frame; the frame is an inverted U-shaped structure; the soil crushing and ridging knife includes a knife shaft and a plurality of blades spirally fixed on the knife shaft; the bearings at both ends of the knife shaft are mounted on the left and right side plates of the frame; a traction connecting seat is fixed to the front of the frame, and a ridge height scraper and left and right ridging side plates are fixed to the tail; the pressing roller is installed on the rear side of the frame; the gearbox is fixed to the top of the frame, and its first output end is transmission-connected to the knife shaft, and the second output end drives the pressing roller through the rear transmission mechanism.

The all-in-one machine described in the above patent can perform ridging operations under the traction of a tractor or other agricultural machinery. The ridge shape is standard and the ridge surface is flat, which can ensure the consistency of the depth of subsequent sowing and planting, is conducive to the growth of the root system of crops, and improves the ability to store water and retain moisture. However, the all-in-one machine is a single-ridge type and can only raise a single ridge surface at a time, resulting in low work efficiency and high labor costs. For this reason, the applicant proposes a double-ridge rotary tillage and ridging all-in-one machine.

DETAILED DESCRIPTION

The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings and specific embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

Embodiment 1:

1 , the double-ridge rotary tillage and ridging pressing integrated machine described in this embodiment includes a frame, a rotary tillage and soil crushing mechanism, a ridging mechanism, a pressing roller 16, a gearbox 7 and a transmission mechanism.

The frame includes an inverted U-shaped frame, frame side panels 2 fixed on the left and right sides of the frame, and a splash-proof top plate 19 fixed on the top of the frame. For areas with less soil, soil collecting plates 1 can be fixed on the front sides of the left and right frame side panels 2 to collect soil and gather soil. More soil is conducive to the establishment of full ridges. A traction connection seat 3 and a traction connection frame 4 are fixed to the front of the frame for connecting traction agricultural machinery. The pressing roller 16 is installed at the tail of the frame.

The rotary tillage and soil crushing mechanism includes a cutter shaft 18 and a plurality of blades fixedly mounted on the cutter shaft 18. The two ends of the cutter shaft 18 are respectively mounted on the left and right frame side plates 2 by bearings. The gearbox 7 is fixed on the top of the frame, and the lower power output end at the bottom thereof is connected to the cutter shaft 18 by transmission. The cutter shaft 18 drives the blades to rotate at a high speed, so that the soil entering the frame space is fully mixed, which plays a role of secondary crushing, and the crushed soil is closed inward and flows out from the rear at an accelerated speed.

The ridging mechanism is provided with two groups, left and right, which are arranged at the rear of the frame, between the rotary tillage and soil crushing mechanism and the pressing roller 16; each group of ridging mechanism includes a height-adjustable ridge scraper 17 and left and right ridging side plates 21. The ridge scraper 17 is arranged longitudinally, and two adjusting screws 24 are fixedly connected to its top edge. The adjusting screws 24 are assembled on the screw seat 23 at the rear of the frame by bolts, and the height of the ridge scraper 17 can be adjusted by adjusting the screws 24. The soil flowing out from the rear of the frame passes through the ridge scraper 17 and the left and right ridging side plates 21 according to the specific ridge surface width and ridge height, and the two groups of ridging mechanisms can form two ridges at one time.

The pressing roller 16 is equipped with two left and right pressing disc groups, which correspond to two groups of ridging mechanisms respectively; each pressing disc group includes two left and right symmetrical pressing discs 20, which are located on the inner side of the corresponding ridging side plate 21 and are fixedly mounted on the pressing roller 16 through a connecting hoop 22, and the spacing between the two pressing discs 20 in the same group can be adjusted according to the ridge width. The two initially formed ridges are compacted and leveled again by the pressing roller 16 and the left and right pressing disc groups to achieve the effect of compacting the outer surface and softening the inner part, thereby obtaining two flat and identical ridge surfaces.

The transmission mechanism includes a transmission shaft 11, two rear output chains 8 and a lower output chain 12; left and right side brackets 10 are fixed on the top surface of the rear part of the frame; both ends of the transmission shaft 11 are respectively assembled on the two side brackets 10 through bearings; both ends of the transmission shaft 11 are respectively connected to the left and right power output ends of the gearbox 7 through the rear output chain 8; the middle part of the transmission shaft 11 is connected to the middle part of the pressing roller 16 through the lower output chain 12. The lower output chain 12 transmits power from the middle to the pressing roller 16, and the lower output chain 12 just corresponds to the position of the furrow, thereby avoiding the ridge surface that needs to be precisely formed and ensuring the integrity of the ridge surface.

Embodiment 2:

As shown in Figure 1, on the basis of Example 1, the double-ridge rotary tillage and ridging pressing machine described in this embodiment also includes a pressing roller adjustment mechanism. The pressing roller adjustment mechanism is provided with two groups, which are respectively located on the left and right sides of the gearbox 7; the pressing roller adjustment mechanism includes a support column 9, a telescopically adjustable pull rod device, two triangular outer brackets 13 and a rear beam 14; the support column 9 is fixed on the top surface of the front part of the frame; the first vertex angles of the two outer brackets 13 are hingedly assembled at the tails of the left and right frame side panels 2, and the two ends of the rear beam 14 are respectively fixed on the second vertex angles of the two outer brackets 13; the two ends of the roller shaft of the pressing roller 16 are respectively assembled on the bearing seats at the bottom corners of the two outer brackets 13; the pull rod device includes a telescopic pull rod 6 and a hand crank 5 for driving the telescopic pull rod 6 to extend and retract; the telescopic pull rod 6 is a sleeve structure, the bottom of the sleeve is hinged on the top of the support column 9, and the end of the telescopic rod is hingedly assembled on the hinge seat 15 of the rear beam 14.

By shaking the hand crank 5, the length of the telescopic rod 6 is controlled, and the outer bracket 13 is rotated with the hinge axis of the first vertex as the rotation center, which plays a role in adjusting the height of the pressing roller 16. The pressing roller 16 rotates at a certain speed to perform active finishing, and the preliminary formed ridges flowing out from the front are compacted and leveled again to achieve the effect of compacting the outer surface and softening the inner part. At the same time, the telescopic rod 6, the two triangular outer brackets 13 and the rear beam 14 can also play a role in stabilizing the pressing roller 16 and reducing the vibration amplitude during the working process.

The technical contents not described in detail in this specification are the prior art well known to those skilled in the art.

The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
