Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
Mulching films are important materials for agricultural production. Film mulching technology has the functions of increasing temperature and maintaining moisture, suppressing weeds, increasing yield and the like, and promotes the significant increase in the level of international agricultural production and the fundamental change in production mode. With the popularization and application of the film mulching technology, the problem of pollution of residual mulching films has become increasingly serious. After the mulching films are used, planters will manually recover the mulching films. Such a recovery mode can only recover the mulching films on the field surface, and more mulching films will remain in the field. If the amount of the mulching films is accumulated year by year, it will not only cause damage to the soil, but also be detrimental to environmental protection. Especially for a plough layer with a certain depth, the residual film (residual mulching film) is more difficult to remove. Especially, residual films and crushed films buried in deep positions of plough layers bring great difficulties to the recovery and severely restrict the development of the residual film recovery business.
In addition, although some existing mechanisms also remove mulching films, they mainly deal with the mulching films on the field surface and only recover visible residual films and large whole residual films. The overall mechanism is large in area and not compact enough, resulting in a large space occupied by the whole machine when idle. Moreover, the residual films can not be easily removed, and human cooperation is required.
According to one aspect of the present invention, there is provided a spring-tooth harrow type plough layer residual film recovery machine, comprising:
a rack;

As described in the background art, there are defects in the prior art. In order to solve the above technical problems, the present invention provides a spring-tooth harrow type plough layer residual film recovery machine. The present invention will be further described below with reference to the accompanying drawings of the specification.
In a typical implementation manner of the present invention, as shown in FIG. 1 and FIG. 2, a spring-tooth harrow type plough layer residual film recovery machine includes a rack 1. A press roller 15 for crushing soil, plough shovels 13 for stripping and breaking films, a rotary tillage mechanism 12 for stripping residual films of plough layers, and a spring tooth elevating mechanism 5 for picking up and conveying the residual films are sequentially arranged at the lower part of the rack 1 from one side to the other side. The spring tooth elevating mechanism 5 is obliquely arranged relative to the rack 1. The spring tooth elevating mechanism 5 realizes cyclic reciprocating movement. The spring tooth elevating mechanism 5 includes a plurality of spring teeth, the spring teeth are arranged in multiple rows on the surface of the spring tooth elevating mechanism 5, and a film removing component 23 for removing residual films is arranged at one side of the top end of the spring tooth elevating mechanism 5.
The rack 1 is further provided with a travelling mechanism 11 between the rotary tillage mechanism 12 and the spring tooth elevating mechanism 5, the travelling mechanism 11 includes a pair of wheels, the wheels are connected with the rack 1 through a lifting component, the pair of wheels are connected through a connecting shaft, the connecting shaft is connected with a support rod, and the support rod is hinged relative to the rack 1. In the present embodiment, a hydraulic lifting rod 10 is selected as the lifting component, and the hydraulic lifting rod 10 is connected with a hydraulic cylinder.
The spring tooth elevating mechanism 5 is supported through a lateral frame 24. The lateral frame 24 is obliquely arranged relative to the rack 1 and is connected with the rack 1. Two ends of the film removing component 23 are supported through the lateral frame. The material of the film removing component 23 is a soft material, such as rubber. Or, rubber is arranged on the surface of the film removing component 23. The film removing component 23 is a film removing plate. The film removing plate is horizontally arranged. Comb teeth can be arranged on one side of the film removing plate. Or, as shown in FIG. 5, the film removing component 23 includes a film removing roller 26 supported through the lateral frame 24. Multiple rows of rubber comb teeth 25 are arranged on the peripheral side of the film removing roller 26. The comb teeth 25 are arranged along the direction of the central axis of the film removing roller. During the operation of the spring tooth elevating mechanism 5, the comb teeth 25 act on the spring teeth, thereby facilitating the removal of the residual films between the spring teeth.
The spring tooth elevating mechanism 6 includes a chain wheel conveying mechanism. The chain wheel conveying mechanism includes a driving chain wheel 20 and a driven chain wheel supported through the lateral frame 24. The driving chain wheel 20 drives a driving chain wheel shaft 1.6 to work. The driven chain wheel is arranged on a driven chain wheel shaft 1.4. The driving chain wheel 20 is higher than the rack. A plurality of fixed pipes 1.3 are uniformly distributed on the surface of the chain wheel conveying mechanism. Adjacent fixed pipes are arranged at a set distance. As shown in FIG. 4, the fixed pipes 1.3 are arranged beyond elevating chains 1.5 on two sides, that is, the length of the fixed pipes 1.3 is longer than the distance between the elevating chain on two sides, so that the fixed pipes 1.3 can be effectively supported through the elevating chains 1.5. The spring teeth 1.1 are fixed on the fixed pipes 1.3. Further, one end of each of the spring teeth 1.1 is arranged on fixed rings 1.2. In the present embodiment, each of the fixed pipes 1.3 is sleeved with a plurality of fixed rings 1.2. The plurality of fixed rings 1.2 are uniformly arranged on the fixed pipes 1.3. The fixed rings 1.2 are fixed on the fixed pipes through bolts or other manners. Adjacent fixed rings 1.2 are arranged at a set distance. Each of the fixed rings 1.2 is provided with one or more spring teeth 1.1. The spring teeth 1.1 are arranged towards the outer side of the spring tooth elevating mechanism 6. The spring teeth 1.1 have a set length so as to be inserted into the field at a set depth during operation. The spring teeth are preferably elastic plastic spring steel wires, and the material is 65 Mn.
Further, two ends of the fixed pipes 1.3 are fixed on the chain plate 1.7. The fixed pipes 1.3 are in surface-to-surface contact with the chain plate 1.7. Both the upper and lower surfaces of the two ends of the fixed pipes are horizontal surfaces. The lower surface is a surface in contact with the chain plate. A threaded hole running through the fixed pipe is formed in the horizontal surface. A threaded hole coaxial with the threaded hole is formed in the chain plate. A bolt passes through the two threaded holes to realize fixation of the spring tooth fixed pipe and the chain plate. The original line contact between the spring tooth fixed pipe and the chain plate is changed into surface-to-surface contact. Under the condition of a fixed impact force F, a contact area S between the spring tooth fixed pipe and the chain plate is increased, so that the overall intensity of pressure P is reduced so as to slow down the damage frequency of a chain harrow of a chain and improve the reliability of the whole machine.
Further, the driving chain wheel shaft 1.6 and the film removing roller 26 in the spring tooth elevating mechanism are arranged parallel to each other. The distance between the film removing roller 26 and the driving chain wheel shaft is much larger than the distance between the film removing roller 26 and the driven chain wheel shaft 1.4. The film removing roller 26 is arranged on one side of the lower side surface of the spring tooth elevating mechanism to prevent the residual films from being driven to the upper side surface of the spring tooth elevating mechanism as much as possible to avoid the winding of the residual films. The rotation direction of the film removing roller 26 (specifically driven by a rotating motor to rotate) is the same as the travelling direction of the spring tooth elevating mechanism, and thus, the movement direction of the comb teeth is opposite to the movement direction of the spring teeth on the corresponding side, so as to facilitate the effective removal of the residual films.
Further, the spring tooth elevating mechanism is provided with a tensioning mechanism 6 (generally a tensioning mechanism of a chain conveying mechanism in the prior art) for adjusting the tension of the elevating chain.
Specifically, the top of the spring tooth elevating mechanism 5 is inclined towards the travelling mechanism and the front side of the rack 1. The spring tooth elevating mechanism 5 moves clockwise or counterclockwise. The rack is provided with a residual film conveying belt 3 on one side of the spring tooth elevating mechanism 5. The residual film conveying belt 3 is arranged above the rotary tillage mechanism 12. Both sides of the residual film conveying belt 3 are provided with film blocking plates, that is, a front film blocking plate 2 and a rear film blocking plate 4, through the rack. The rear film blocking plate 4 is arranged obliquely and backwards relative to the residual film conveying belt 3 to prevent the residual films from falling and being wound on the spring tooth elevating mechanism 5 again. The conveying direction of the residual film conveying belt 3 is consistent with the width direction of the rack 1. The rack 1 in the width direction is hollowed out on both sides or one side of the residual film conveying belt 3. In this way, after the residual films are accumulated to a certain height, the residual film conveying belt 3 is driven by a residual film conveying belt driving component 18, such as a driving motor, to convey the residual films, so that the collected residual films are conveyed away from the residual film conveying belt 3. In addition, a film guiding plate 9 is also obliquely arranged behind the travelling mechanism 11on the side of the rack 1, and has a function of assisting the spring teeth to convey the residual films to the residualfilm conveying belt.
Further, in the prior art, a spring-tooth chain harrow type residual film recovery machine picks up residual films through spring teeth, and the picked residual films are conveyed upwards along a film conveying support plate and finally fall into a film collecting box. However, when the spring teeth enter the soil to pick up films, soil blocks/stone blocks in soil plough layers will be sandwiched between adjacent spring teeth. When the residual films are lifted up with the spring teeth, the soil blocks/stone blocks also move upwards and fall into the film collecting box with the residual films, so that a large number of soil blocks/stone blocks are mixed in the recovered residual films, which brings many problems to the subsequent processing of the residual films. In the present embodiment, a plurality of impurity removing piles 9.1 are arranged on the film guiding plate 9. The installation angle and length of the impurity removing piles 9.1 need to meet the following conditions: during the upward movement of the spring teeth along the film guiding plate 9, one of the straight rods of the spring teeth 11 can be in contact with the spring teeth and generates deformation.
As a further technical solution, the arrangement mode of the impurity removing piles 9.1 is the same as the arrangement mode of the spring teeth, and specifically, the impurity removing piles and the spring teeth are arranged according to actual needs.
As a further technical solution, the impurity removing piles 9.1 are of a cylindrical structure.
As a further technical solution, the impurity removing piles 9.1 are made of a metal material with certain hardness. In the present invention, the impurity removing piles can adopt a round steel structure, but not limited to round steel which can be replaced with rectangular pipes, angle steel, seamless pipes, and the like.
The impurity removing piles and the film guiding plate may be in detachable connection, such as bolted connection, threaded connection and clamped connection, or may be in non-detachable connection, such as welding and gluing, and the connection mode can be selected according to actual needs. The impurity removing piles and the film guiding plate may also be integrally formed, or may be combined and connected together, preferably integrally formed.
The impurity removing piles are additionally arranged on the film guiding plate. During the upward movement of the spring teeth along the film guiding plate, the spring teeth are in contact with the impurity removing piles and generate deformation. As the spring teeth continue to move upward, the deformation of the spring tooth straight rods increases, so that the two straight rods are not positioned in the same plane, and thus the soil blocks/stone blocks mixed between the two spring tooth straight rods fall.
The installation and arrangement of the impurity removing piles on the film guiding plate are shown in the figure. The arrangement of the impurity removing piles needs to ensure that the impurity removing piles can collide with the straight rod of one of the spring teeth, and can only collide with one straight rod of the corresponding spring tooth.
The structure of the spring teeth is shown in FIG. 14. The spring teeth include integrally formed spring tooth straight rods and spring tooth spirals. The spring tooth spirals are sleeved over the spring tooth fixed pipe. Two spring tooth straight rods are provided. During actual operation, it is enough to ensure that one of the spring tooth straight rods collides with the impurity removing piles. During the upward movement of the spring teeth along the film guiding plate, the spring teeth are in contact with the impurity removing piles and generate deformation. As the spring teeth continue to move upward, the deformation of the spring tooth straight rods increases, so that the two straight rods are not positioned in the same plane, and thus the soil blocks/stone blocks mixed between the two spring tooth straight rods fall. The impurity content of the recovered residual films is greatly reduced so as to provide convenience for secondary utilization of the residual films.
In addition, a height-adjustable depth limiting roller 8 is arranged at the bottom of the spring tooth elevating mechanism 5. Two sides of the depth limiting roller 8 are connected with a second adjusting component 7. The second adjusting component 7 is connected with a transverse support rod 19. The transverse support rod 19 is connected with a lateral frame 24. The second adjusting component 7 is obliquely arranged relative to the transverse support rod, so that the depth limiting roller 8 can level the soil. Certainly, the main function of the depth limiting roller 8 is to limit the depth, and the height of the depth limiting roller is adjusted through the second adjusting component so as to control the depth of the spring teeth in the soil. The second adjusting component 7 includes second side plates arranged on two sides of the depth limiting roller 8. The second side plates are provided with a plurality of second bolt holes. The height adjustment of the depth limiting roller 8 is realized through the connection between different second bolt holes and the depth limiting roller 8.
Correspondingly, the height of the press roller 15 relative to the rack 1 can be adjusted. Similarly, two sides of the press roller 15 are connected with a first adjusting component. The top of the first adjusting component is connected with the rack. The first adjusting component includes first side plates arranged on two sides of the press roller 15. The first side plates are provided with first bolt holes. The height adjustment of the press roller is realized through the connection between different first bolt holes and the press roller.
It should be noted that both the press roller 15 and the depth limiting roller 8 are common press rollers.
A plurality of plough shovels 13 are provided. The plurality of plough shovels 13 are connected with the rack through a plough shovel frame. The plough shovels 13 are detachably connected to the plough shovel frame. The two ends of the plough shovel frame are connected with the rack. The sides of the plough shovel frame are provided with bolt holes of different heights. The connection with the plough shovels 13 and the height adjustment are realized through different bolt holes. The working surface of the plough shovels 13 is arranged towards the direction of the press roller 15. The plough shovels 13 strip and break the residual films on the field surface from the ground, the film stripping operation is performed, and large whole residual films are also broken, thereby effectively solving the problem that the residual films wind the rotary tillage mechanism 12.
The rack 1 is provided with a traction component above the press roller 15 to connect with a traction engine. The traction engine may be a tractor, and the traction component may be a traction ring to connect with the tractor. The rack 1 is provided with a power input component 17. The power input component 17 is separately connected with the rotary tillage mechanism 12 and the spring tooth elevating mechanism 5. The power input component 17 may be a motor or a hydraulic cylinder. The power input component 17 drives the rotary tillage mechanism 12 and the spring tooth elevating mechanism 5 to move.
Specifically, the power input component 17 drives the rotary tillage mechanism 12 to move. The rotary tillage mechanism 12 is a commonly used agricultural rotary tillage mechanism. The rotary tillage mechanism 12 drives the spring tooth elevating mechanism 5 to move through conveying components. As shown in FIG. 3, specifically, the conveying components are two groups of chain wheel conveying mechanisms. The rotary tillage mechanism 12 drives a first chain wheel conveying mechanism to move. The first chain wheel conveying mechanism is meshed with an intermediate chain wheel 21. The intermediate chain wheel 21 drives the driving chain wheel to move through a chain so as to drive the spring tooth elevating mechanism 5 to move. During the power transmission, the exposed parts are provided with safety protection covers. The safety protection covers are detachably connected with the rack 1. The shapes of the safety protection covers are not limited here.
As a further technical solution, due to the light, thin and strip-like physical properties of residual films, the residual films thrown by a rotary tillage blade will continue to rotate along the moving track of the rotary tillage blade. After the whole machine works for a period of time, many residual films are wound on a rotary tillage blade shaft, which greatly affects the working performance of the rotary tillage blade. In view of this problem, in the present embodiment, a film pressing roller 29 is additionally arranged behind a rotary tillage device, and the axis of the film pressing roller is parallel to the axis of the rotating shaft of the rotary tillage mechanism. The residual film thrown by the rotary tillage device collides with the film pressing roller so as to destroy the original moving track of the residual film. The thrown residual film is pressed on the field surface after colliding with the film pressing roller, and then picked up by the spring teeth.
The structure of the film pressing roller 29 in the present invention is shown in FIG. 12. The film pressing roller includes a film pressing roller body and a connecting shaft. The film pressing roller body may be of a hollow structure or a solid structure. When the film pressing roller body is of a hollow structure, the connecting shaft passes through the film pressing roller body, and both ends extend outside the film pressing roller and are connected with an installation frame 31 of the rotary tillage device through a connecting plate 30.
The connecting plate 30 and the installation frame 31 of the rotary tillage device may be in detachable connection, such as bolted connection as shown in FIG. 3, or may be in non-detachable connection, such as welding, and the connection mode can be selected according to actual needs.
The present embodiment further discloses a use method of the spring-tooth harrow type plough layer residual film recovery machine, including the following contents:
A rack moves forward with the movement of a traction engine.
A press roller presses a field surface to crush hardened soil to effectively separate the film from the soil, and plays roles in limiting depth and supporting the rack together with a travelling mechanism.
Plough shovels strip and break the residual films on the field surface from the ground.
A rotary tillage mechanism strips residual films of plough layers for the field soil, and conveys the residual films to the field surface.
A spring tooth elevating mechanism circularly acts. The spring teeth effectively pick up the residual films in the field during the contact with the field surface to drive the residual films to move upward so as to convey the residual films to a top end of the spring tooth elevating mechanism. The film removing component has a certain blocking effect on the spring teeth with residual films, so that under the action of thefilm removing component, the residual films are removed, and the residual films are collected on the surface of the residual film conveying belt by means of the arrangement of the front and rear film blocking plates.
When the residual films are accumulated to a set height, the residual film conveying belt driving component can be started, the residual films are removed from the side of the rack. After the films are removed, the residual film conveying belt driving component is closed and the operation is continued.
The foregoing descriptions are merely preferred embodiments of the present invention, but are not intended to limit the present invention. A person of ordinary skill in the art may make various modifications and variations to the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
