Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural machinery chassis, and particularly relates to a self-propelled chassis special for a residual film recycling all-in-one machine and the residual film recycling all-in-one machine. BACKGROUND

[0002] The statements herein merely provide background technology related to the present application, and do not necessarily constitute prior art.

[0003] At present, according to incomplete statistics, there are more than 100 types of residual film recycling machines. However, the research on residual film recycling machines focuses on improving the residual film recycling rate and reducing the impurity rate of residual film, and pays attention to improving the operation performance and intelligent level of the machine, but lacks the research and development of multifunctional combined operation machine and large-scale self-propelled residual film recycling machine, which cannot meet the needs of large-scale operation, and one of the important reasons is the lack of research on self-propelled chassis special for multifunctional residual film recycling machine. Due to the difference in function or operation mode, the difference in design concept / underlying logic leads to the fact that the chassis of other agricultural machines cannot be used on the residual film recycling machine, and the specific reasons are described below.

[0004] Firstly, the power mode is different. Most of the other agricultural machines are once contacted with the operation object, and then the subsequent components complete multiple functions, such as the corn harvester header harvesting corn, the straw being crushed and thrown to the ground, and the fruit cluster being peeled and entering the granary, which is a relatively complete system, and does not need multiple power outputs, and the internal mechanical transmission can be easily used to realize power transmission. However, the residual film recycling machine needs to bundle the straw and package the residual film, and there are two different operation objects, i.e. the straw and the residual film, and the machine cannot complete all operations at one time, so the straw bundling and the residual film packaging need to be two relatively independent working systems, the two positions are far apart, there is no function intersection between them, and independent power input is needed. If the chassis of other agricultural machines is used for the residual film recycling machine, the mechanical drive (referring to self walking) and the mechanical transmission (referring to the driving of working components) are adopted, which has large weight, complex structure, large transmission loss, and few power output points. However, the residual film recycling machine has many working components and large weight, and needs independent power input, so the weight of the chassis should be reduced as much as possible, the reliability should be enhanced, and the power output points should be increased. The mechanical drive of the traditional chassis is not suitable for the self-propelled residual film recycling machine.

[0005] Secondly, the chassis layout is different. Taking the corn machine chassis as an example, because the peeling device and the grain box are arranged in parallel on the corn harvester frame, the center of gravity is relatively low, while the straw bundling device needs to be arranged above the residual film packaging component due to the limitation of structure and position, and the center of gravity is relatively high. If the chassis of the corn harvester is used for the residual film recycling machine, the overall center of gravity of the residual film recycling machine will be high, the stability will be poor, the residual film recycling machine will be prone to overturning, and the straw bale will be prone to scattering after falling.

[0006] The chassis of other agricultural machines is as same as that of the corn harvester, and is designed with high targeting, and functions different from the requirements of straw bundling and residual film packaging, so that if directly applied to the residual film recycling machine, the problems of poor adaptability, single function, poor stability and traction will occur, and therefore, the existing agricultural machine chassis cannot be applied to the residual film recycling machine.

[0038] In a typical embodiment of the present application, asFigure 1 As shown, a multifunctional residue film recycling all-in-one machine special self-propelled chassis is proposed, which comprises an upper frame 7 and a lower frame 4. The upper frame 7 and the lower frame 4 jointly form the frame of the self-propelled chassis, and other devices on the chassis are installed on the frame. The upper frame 7 and the lower frame 4 are connected by a connecting mechanism and a quick hitch mechanism 11 to form a whole.

[0039] The self-propelled chassis further comprises an engine, a hydraulic system, a walking system, etc. The engine 3 provides power for the whole machine, including providing power for the hydraulic system. The hydraulic system is divided into a walking hydraulic system and a working hydraulic system, which respectively provide power for the walking system and the working components. The walking hydraulic system transmits power to the drive axle through a hydraulic oil circuit to drive the drive wheels to rotate and realize the walking function. The working hydraulic system transmits power to the working components (straw chopping mechanism, straw packaging mechanism and residue film recycling operation mechanism) in front, rear and upper positions through three hydraulic oil circuits, respectively, and reserves hydraulic power interfaces 10 for the three working components. The upper frame separates the rear working component and the upper working component, and can install the upper working component on the upper frame to expand the capacity of the whole machine and meet the installation requirements of multiple working components of the multifunctional chassis.

[0040] The upper frame 7 is also fixedly provided with an oil tank 8 to provide fuel for the engine.

[0041] The walking system comprises a drive axle 2 and a steering axle 6. The drive axle 2 is arranged at the front of the chassis and is powered by the walking hydraulic system from the engine. The steering axle 6 is arranged at the rear of the chassis and is controlled by the cab control system to realize the steering of the chassis. The front of the drive axle 2 is provided with a front hitch mechanism 9 for the work and lifting of the front working component.

[0042] The self-propelled chassis adopts a wheeled walking device, and the drive axle and the steering axle are connected with the wheels to realize the walking of the whole chassis. The intelligent hydraulic control system is used to control the engine, hydraulic system, etc. The intelligent hydraulic control system is arranged in the cab 1, which is installed at the front upper part of the frame and is a control room. The lower frame 4 in the frame is the basis of the whole machine, and the drive axle 2, the steering axle 6, the engine 3 and the cab 1 are all installed on the lower frame 4. The quick hitch mechanism 11 arranged in the middle of the lower frame 4 can realize the quick hitch of the rear large working component.

[0043] The connecting mechanism comprises a front connecting rod 12, an intermediate connecting rod 14, an outer connecting rod 15, a rear connecting rod 16 and a transverse reinforcing rod 17. The front connecting rod 12, the intermediate connecting rod 14, the outer connecting rod 15 and the rear connecting rod 16 are vertically arranged, and the two ends of the front connecting rod 12, the intermediate connecting rod 14, the outer connecting rod 15 and the rear connecting rod 16 are respectively connected to the upper layer rack 7 and the lower layer rack 4, so as to connect the upper layer rack and the lower layer rack together and increase the strength between the two racks. The outer connecting rod 15 can be connected to the outer side of the upper and lower layer racks, so as to avoid the space of the residual film recycling working part.

[0044] Specifically, the front connecting rod 12 is connected between the front parts of the upper layer rack 7 and the lower layer rack 4, the intermediate connecting rod 14 is connected between the middle parts of the upper layer rack 7 and the lower layer rack 4, and the rear connecting rod 16 is connected between the rear parts of the upper layer rack 7 and the lower layer rack 4. The transverse reinforcing rod 17 is transversely arranged and can be connected between the vertically arranged front connecting rod 12, the intermediate connecting rod 14, the outer connecting rod 15 and the rear connecting rod 16. The intermediate connecting rod 14 can be provided in plurality. The transverse reinforcing rod is connected between the front connecting rod 12 and part of the intermediate connecting rods 14, and the transverse reinforcing rod is also connected between part of the intermediate connecting rods 14 and the outer connecting rod 15 and the rear connecting rod 16, so that the whole rack structure is more stable.

[0045] The quick hitching mechanism 11 is composed of a hitching rod 13 and a control oil cylinder 18, and there are two groups of the quick hitching mechanism 11 which are symmetrically distributed on the left and right sides of the lower layer rack. The bottom of the hitching rod 13 is installed on the lower layer rack, and the hitching rod 13 can rotate around the fixed point of the lower layer rack, that is, the hitching rod 13 is hinged to the lower layer rack 4.

[0046] The hitching rod 13 is in the form of a telescopic rod, and the length of the hitching rod 13 can be changed by hydraulic control. The lower end of the hitching rod 13 is hinged to the lower layer rack 4, and the upper end of the hitching rod 13 is provided with a quick hitching hook which is used for installing the residual film recycling working mechanism.

[0047] The bottom of the control oil cylinder 18 is installed on the lower layer rack, and the top of the control oil cylinder 18 is installed on the lower part of the hitching rod. The control oil cylinder 18 can rotate around the fixed point of the lower layer rack, that is, the control oil cylinder 18 is hinged to the lower layer rack 4. The length of the control oil cylinder 18 can be changed by hydraulic control. The control oil cylinder is connected to a hydraulic system.

[0048] The bottom of the hitching rod 13 and the bottom of the control oil cylinder 18 are spaced apart by a certain distance, and the bottom of the hitching rod 13 and the bottom of the control oil cylinder 18 can be fixedly installed at the same height of the lower layer rack 4. The control oil cylinder 18 is hinged to the lower side of the hitching rod 13. The movement of the quick hitching hook in any direction and at any position can be realized by the extension and retraction of the control oil cylinder and the extension and retraction of the hitching rod.

[0049] The working principle of the quick hitch mechanism is that the quick hitch hook at the upper end of the hitching rod 13 is used for hitching the residue film recycling operation mechanism, the whole can rotate around the connection position of the lower end and the lower frame, the control oil cylinder can also rotate around the connection position of the lower end and the lower frame, the hitching rod is driven to rotate by the extension and retraction of the hydraulic control oil cylinder, and the hitching rod is also rotated and retracted, so as to realize the arbitrary movement of the hitching point within a certain range.

[0050] The residue film recycling operation mechanism is provided with a hitching ring in front and a press roller below as a supporting point. When quick hitching, the control oil cylinder is elongated to drive the hitching rod to rotate, the included angle between the hitching rod and the ground is reduced, and the active section of the hitching rod is elongated at the same time. The quick hitch hook is connected with the hitching ring. The residue film recycling operation mechanism realizes force balance under the upward pulling force of the hitching rod and the supporting action of the self-press roller. Then the hitching rod and the control oil cylinder are retracted at the same time, the hitching rod drags the residue film recycling operation mechanism forward. Because the self-gravity of the residue film recycling operation mechanism is very large and the supporting point is on the press roller, the residue film recycling operation mechanism itself will not rotate and keep a horizontal state to be dragged to the predetermined installation position by the hitching rod. The residue film recycling operation mechanism is installed on the lifting mechanism by the self-reserved installation position, and the quick hitching process is completed. The hitching rod is then separated from the residue film recycling operation mechanism, the control oil cylinder is tightened, and the quick hitch hook is hitched on the upper frame as a reinforcing mechanism between the upper and lower frames.

[0051] In a further embodiment, a lifting mechanism 5 is arranged between the upper frame 7 and the lower frame 4, and the lifting mechanism 5 is installed between the upper and lower frames through two intermediate connecting rods 14.

[0052] The lifting mechanism includes a lifting frame 20, a hydraulic oil cylinder 21 and a residue film recycling hitching seat 22. The lifting frame is located between the two intermediate connecting rods 14. The two intermediate connecting rods 14 are installed between the middle parts of the upper and lower frames, oppositely installed and arranged at a certain distance. The opposite surfaces of the intermediate connecting rods 14 are hollow to form guide grooves, and the outer side of the lifting frame 20 is arranged in the guide grooves and can slide up and down in the guide grooves.

[0053] The hydraulic oil cylinder 21 is installed on the lifting frame 20 at the top and on the lower frame 4 at the bottom. The lifting frame slides up and down in the guide grooves by the extension and retraction of the hydraulic oil cylinder.

[0054] The residue film recycling hitching seat 22 is divided into upper hitching seats and lower hitching seats and is welded on the lifting frame. The upper hitching seats and the lower hitching seats are arranged in two groups, and the two groups of upper hitching seats and lower hitching seats are correspondingly arranged. The upper hitching seats and the lower hitching seats of each group are oppositely arranged and connected with the hitching points reserved on the residue film recycling operation mechanism during hitching, so as to realize the fixed connection of the residue film recycling operation mechanism.

[0055] In possible embodiments, the lifting frame 20 is of a frame structure, which can be arranged in the following form: comprising upper and lower oppositely spaced transverse connecting rods, and vertical connecting rods connected between both ends of the two transverse connecting rods; the lifting frame is located in the space between the upper and lower frames, the side of the lifting frame is connected with the guide groove of the middle connecting rod, and the residual film recovery hanging seat 22 is fixed on both sides of the lifting frame, and the hydraulic oil cylinder 21 is hinged with the upper part of the lifting frame 20.

[0056] The working principle of the lifting mechanism is that the lifting mechanism as a whole is extended and retracted by the hydraulic oil cylinder, so as to drive the lifting frame to slide up and down in the guide groove, realize the vertical movement of the lifting frame relative to the upper frame and the lower frame, and drive the residual film recovery operation mechanism to move up and down as a whole, so as to realize the switching of the scene and the operation mode.

[0057] In the working state, the hydraulic system controls the hydraulic oil cylinder to shorten the lower end as the fulcrum, drives the lifting frame to move downward, realizes the descent of the residual film recovery operation mechanism, and the film lifting spring tooth on the residual film recovery operation mechanism enters the soil to reach the working position, enters the working mode, after the operation is completed, the hydraulic oil cylinder is extended with the lower end as the fulcrum, drives the lifting frame to move upward, realizes the lifting of the residual film recovery operation mechanism, and the residual film recovery operation mechanism as a whole leaves the ground, and is locked after meeting the scene switching demand, and the machine enters the scene switching mode.

[0058] The front hanging mechanism 9 comprises a front supporting oil cylinder 23 and an upper hanging seat 19, the lower end of the front supporting oil cylinder 23 is welded on the drive axle 2, and the upper end is connected with the lower connecting point of the straw chopping mechanism; the upper hanging seat 19 is welded on the upper frame and connected with the upper connecting point of the straw chopping device. The front supporting oil cylinder 23 is connected with the hydraulic system.

[0059] In the working state, the hydraulic system controls the front supporting oil cylinder to contract, the oil cylinder is limited to realize height locking after reaching the working position, the straw chopping mechanism enters the working state, after the operation is completed, the hydraulic system controls the front supporting oil cylinder to extend, the straw chopping mechanism rotates upward around the upper hanging seat as the center, realizes the overall position lifting, and enters the scene switching state.

[0063] The above merely provides preferred embodiments of the present application but should not be used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
