Description

Technical Field

[0001] The utility model relates to a rotary tiller, in particular to an anti-winding six-blade rotary tiller. Background Art

[0002] In order to improve the planting capacity of the land, it is often necessary to plow the land before sowing. The plowed land has larger soil gaps and better air permeability. Water and air can enter the soil well and be well retained. Plowing the land can make the soil soft, which is suitable for the growth of crop roots and nutrient absorption.

[0003] With the development of the times, the way of plowing has gradually developed from the more primitive iron plow to the modern fully automatic mechanical plowing method, which can greatly save labor costs and effectively improve production efficiency. Common plowing machines include rotary tillers, excavators, etc.

[0004] A rotary tiller plows the land by cutting the ground with high-speed rotating blades. When the high-speed rotating blades come into contact with a large number of weeds and tree roots in the land, they often cause the weeds to entangle around the rotating shaft. When there are too many entangled weeds, the speed of the rotary tiller will decrease due to the increase in resistance, thereby reducing the efficiency of rotary tillage. Summary of the invention

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0043] See also Figure 1 to Figure 9 As an embodiment of the utility model, the anti-winding six-blade rotary tiller comprises a chassis 1 and a plurality of rotating discs 4 arranged in the chassis 1; six rotary tilling blades 401 are installed on the rotating disc 4;

[0044] The chassis 1 is provided with a rotary tillage mechanism, which can drive the turntable 4 to rotate, thereby driving the six rotary tillage blades 401 to rotate, so that the rotary tillage blades 401 can rotary till the land;

[0045] The rotating disk 4 is provided with a fixed sawtooth blade 9; the chassis 1 is provided with a shearing mechanism, and the shearing mechanism is connected with a swinging sawtooth blade 10; the shearing mechanism can drive the swinging sawtooth blade 10 to swing back and forth when the rotary tillage mechanism is in operation, so as to shear the debris;

[0046] The chassis 1 is also provided with a cleaning mechanism; a cleaning rod 11 is connected to the cleaning mechanism, and the cleaning mechanism can drive the cleaning rod 11 away from or close to the rotation center of the turntable 4 when the rotary tillage mechanism is in operation to clean the attached soil.

[0047] In this embodiment, the rotary tillage mechanism drives the turntable 4 to rotate to drive the rotary tillage blade 401 to rotate, and the tangential force generated by the rotation of the rotary tillage blade 401 is used to cut the land and loosen the compacted soil. Rotating the land by rotation can improve the soil loosening efficiency, thereby improving production efficiency and effectively saving labor costs.

[0048] The action of the rotary tillage mechanism drives the shearing mechanism to drive the swinging sawtooth blade 10 to swing back and forth. The entangled debris is cut into pieces by the mutual engagement and shearing of the sawtooth portion on the swinging sawtooth blade 10 and the sawtooth portion on the fixed sawtooth blade 9, so as to avoid too much entangled debris and reduce the rotary tillage efficiency of the rotary tillage mechanism.

[0049] The action of the rotary tillage mechanism drives the cleaning mechanism to move away from or close to the rotation center of the turntable 4, and the soil attached to the turntable 4 is swept away by the action of moving away from or close to the turntable 4 to prevent excessive attachment of soil and reduce the rotary tillage efficiency of the rotary tillage mechanism.

[0050] Through the synchronous cooperation of the rotary tillage mechanism, the shearing mechanism and the cleaning mechanism, the weeds, tree roots and other debris entangled on the rotary tiller can be sheared while the land is rotary tilled, and the soil attached to the rotary tiller during the rotary tillage process can be cleaned, so as to improve the rotary tillage efficiency of the rotary tiller.

[0051] As a further solution of the utility model, the rotary tillage mechanism includes a motor 2 installed on the chassis 1; a rotating shaft 3 is rotatably installed on the chassis 1, and the rotating shaft 3 is connected to the output end of the motor 2 through a belt; a mounting disk 301 is installed at one end of the rotating shaft 3; a connecting rod 101 connected to the chassis 1 is rotatably installed on the mounting disk 301; a stationary bevel gear 102 is installed on the connecting rod 101; and the turntable 4 is installed on the rotating shaft 3.

[0052] In this embodiment, the motor 2 is started, and the shaft 3 rotates synchronously with the action of the motor 2, thereby driving the turntable 4 to rotate, so that the rotary tillage blade 401 rotates, and the tangential force generated by the rotation of the rotary tillage blade 401 loosens the compacted land, so that the land after rotary tillage meets the sowing requirements; and when the shaft 3 rotates, the mounting plate 301 also rotates. Rotating the land through rotation can improve the soil loosening efficiency, thereby improving production efficiency and effectively saving labor costs.

[0053] As a further solution of the utility model, the shearing mechanism includes a first bevel gear 5 mounted on the mounting plate 301 and meshing with the stationary bevel gear 102; a rotating plate 6 is mounted on the first bevel gear 5, and a protruding column 601 is mounted on the rotating plate 6;

[0054] The turntable 4 is provided with a slot 402 which is slidably engaged with the swinging serrated blade 10; the mounting plate 301 is provided with a through slot; a connecting rod 8 connected to the swinging serrated blade 10 is slidably engaged in the through slot; a deflection rod 7 is connected to the connecting rod 8, and a deflection slot 701 which is slidably engaged with the raised column 601 is provided on the deflection rod 7.

[0055] In this embodiment, when the mounting plate 301 rotates with the rotating shaft 3, the first bevel gear 5 is driven to rotate around the connecting rod 101, and during the rotation, the first bevel gear 5 is meshed with the stationary bevel gear 102, so that the first bevel gear 5 rotates.

[0056] The rotating disk 6 rotates with the rotation of the first bevel gear 5, thereby driving the protruding column 601 to rotate, and the protruding column 601 drives the deflection rod 7 to move back and forth toward and away from the mounting disk 301 by sliding engagement with the deflection groove 701, thereby driving the connecting rod 8 to slide back and forth in the through groove. The swinging sawtooth blade 10 slides back and forth in the notch 402 driven by the connecting rod 8, and the serrated parts on the swinging sawtooth blade 10 and the serrated parts on the fixed sawtooth blade 9 are engaged and sheared to cut up the entangled debris, so as to avoid too much entangled debris and reduce the rotary tillage efficiency of the rotary tillage mechanism.

[0057] As a further solution of the utility model, the cleaning mechanism includes a second bevel gear 12 installed on the mounting plate 301 and meshing with the stationary bevel gear 102; a follower rod 13 is installed on the second bevel gear 12; a second slide groove 1301 is provided on the follower rod 13; a lifting block 14 connected to the cleaning rod 11 is movably installed on the follower rod 13, and a cylinder 1401 slidingly engaged with the second slide groove 1301 is installed on the lifting block 14; a first slide groove 403 slidingly engaged with the cleaning rod 11 is provided on the turntable 4.

[0058] In this embodiment, when the mounting plate 301 rotates with the rotating shaft 3, the second bevel gear 12 is driven to rotate around the connecting rod 101, and during the rotation process, the second bevel gear 12 is meshed with the stationary bevel gear 102, so that the second bevel gear 12 rotates. The rotating second bevel gear 12 drives the follower rod 13 to rotate, thereby driving the second slide slot 1301 to slide with the cylinder 1401;

[0059] The second slide groove 1301 is divided into an inclined upward part, an inclined downward part and a straight part; when the cylinder 1401 slides in the inclined upward part, it will drive the lifting block 14 to approach the second bevel gear 12, thereby driving the cleaning rod 11 to slide in the first slide groove 403 toward the rotating shaft 3; when the cylinder 1401 slides in the inclined downward part, it will drive the lifting block 14 away from the second bevel gear 12, thereby driving the cleaning rod 11 to slide in the first slide groove 403 in the direction away from the rotating shaft 3; and when the cylinder 1401 slides in the straight part, the cleaning rod 11 does not slide.

[0060] The soil attached to the rotary disc 4 and the rotating shaft 3 is cleaned off by the movement of moving away from or approaching, so as to prevent excessive attachment of soil from reducing the rotary tillage efficiency of the rotary tillage mechanism.

[0061] As a further solution of the utility model, the cleaning mechanism further includes a telescopic sleeve 404 installed on the turntable 4 ; a telescopic column 1101 connected to the cleaning rod 11 is slidably engaged in the telescopic sleeve 404 .

[0062] In this embodiment, when the cleaning rod 11 slides toward the rotating shaft 3, the telescopic column 1101 slides inward in the telescopic sleeve 404; when the cleaning rod 11 slides away from the rotating shaft 3, the telescopic column 1101 slides outward in the telescopic sleeve 404. Since the length of the cleaning rod 11 is greater than the length of the rotating shaft 3, the sliding cooperation between the telescopic sleeve 404 and the telescopic column 1101 can prevent the cleaning rod 11 from bending or breaking during the operation, thereby increasing the service life of the rotary tiller.

[0063] As a further solution of the utility model, a slope surface is provided on a side of the rotary tilling blade 401 close to the rotation direction of the motor 2, and the rotary tilling blade 401 is in an "L" shape.

[0064] In this embodiment, the "L" shape of the rotary tillage blade 401 can increase the contact area with the ground, thereby increasing the rotary tillage efficiency of the rotary tillage mechanism; the setting of the slope surface can reduce the resistance of the rotary tillage blade 401 to rotary tillage, thereby increasing the rotary tillage efficiency.

[0065] As a further solution of the present invention, a connecting frame is installed on the chassis 1, and the connecting frame is used to connect a mobile device.

[0066] In this embodiment, different mobile equipments are connected by a connecting frame, so that the rotary tiller can have a wider range of uses.

[0067] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
