Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and particularly relates to a fully automatic reed baler. Background Art

[0002] Reeds are mostly harvested manually during the harvesting process, and then in order to facilitate stacking and reduce the floor space of the reed stack, the harvested reed stalks often need to be compressed and packaged. The existing packaging methods include manual processing and mechanical processing. The traditional mechanical packaging uses a special compression baler, where the manual filler is compressed by a weight or a hydraulic cylinder, and then sent to the baling machine by other mechanisms or manual labor to complete the baling. This method is not only inefficient, but the compressed material will inevitably affect its compression effect after transportation, making the baling effect unsatisfactory. In order to solve the above problems, a fully automatic reed baler has been designed. By combining the functional components of feeding, conveying, compression, and baling, it becomes an automatic baling machine. However, the existing balers of this type have various problems, such as: the feeding device adopts a spiral or fixed tooth roller body to rotate and feed. Although this mechanism can smoothly pick up the reed stems on the ground, due to the lack of a discharge mechanism, the reed stems are often bent and stuck in the feeding device and cannot be unloaded smoothly; and because reeds are mostly planted in lake areas, river banks and other tidal flats, large machinery cannot enter. Therefore, under normal conditions, reeds are harvested manually and transported to flat areas for initial stacking and then compressed and packaged. The design of this mechanism is only applicable to reeds laid flat on the ground, but not to piled reeds. In addition, the existing machinery is arranged in a combination of functional parts, and each functional part only plays its own role, which results in a series of problems such as huge size of the whole machine, cumbersome working steps, complex operating system, and high failure rate.

[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, the fully automatic reed baler described in the present invention is easy to operate and has a high degree of automation. It is suitable for reed layers spread on the ground or preliminarily piled reed piles. It has strong adaptability and greatly reduces labor intensity and greatly improves production efficiency through mechanical operation.

[0016] Second, the fully automatic reed baler described in the present invention, the feeding device in the present invention utilizes a simple eccentric motion principle to realize the extension and retraction of the claw while rotating to baling the material so as to realize baling and releasing the material at a specified position. Specifically, during the rotation of the roller body, the extension and retraction of the claw facilitates the insertion of the claw into the reed pile to baling the material. When the claw is moved to the feed port of the conveying device, the claw just retracts into the roller body, and the material on the claw is released to the feed port. No specific setting of the control system is required, and it can be achieved through a simple mechanical method, ensuring that the mechanism is firm and durable with a low failure rate. The conveying device can lift the feeding device end through the push of the hydraulic cylinder, so that the device can be used for a series of operations such as picking up, compressing, and baling the ground reeds. At the same time, the feeding device that can be adjusted up and down can make the device suitable for compressing and baling the reed stalks that are initially piled, and has a wide range of applications.

[0017] Thirdly, the fully automatic reed baling machine described in the present invention adopts a metal conveying chain as the conveying device. During the conveying process of the reed stalks, gravity causes the initial compression during the conveying process, so that the disordered reed stalks fit neatly when entering the lower mechanism. The pre-compression conveying mechanism reduces the conveying space through the setting of its own structure, compresses and combs the reed stalks, plays a pre-compression role, and prepares for the subsequent smooth shearing.

[0018] Fourthly, the fully automatic reed baler described in the present invention is equipped with a multi-stage pushing mechanism to enable the system to perform reciprocating motion while cutting, which matches the conveying speed of the baler, ensuring that the conveying mechanism of the entire reed baler is uninterrupted before and after the cutting action, and realizing the conveying and cutting of the machine without pause. At the same time, it is equipped with a synchronization device to make the two ends of the blade always move synchronously, thereby ensuring the stability of the blade and the cutting effect.

[0019] Fifth, the full-automatic reed baler described in the present invention, the material drop bin serves as a transition device of the whole machine, which not only limits the cut reed poles to improve the neatness of the cut reeds, but also lowers the reed poles upstream of the whole machine from a high place to a low place, thereby compressing the height of the whole machine and improving the coordination of the whole baler.

[0020] Sixth, the full-automatic reed baler described in the present invention has a conveying mechanism composed of a conveyor belt and the like as a compression front desk in direct contact with the material in the compression device. This structural design can effectively simplify the structure of the whole machine, that is, the conveying mechanism can be used as a functional part of the compression device and also as a conveying functional part, without the need to set up a separate conveying system. At the same time, the extrusion and conveying of the device are realized in the same area, that is, the conveying can be realized in a compressed state, avoiding the rebound phenomenon caused by the change of the conveying environment after compression and then conveying, thereby improving the material compression rate of the whole machine; at the same time, the arrangement of the mechanism can compress the material first and then convey it in a compressed state according to needs, or it can be compressed and conveyed simultaneously, thereby improving the output efficiency of the whole machine.

[0021] Seventh, in the full-automatic reed baler described in the present invention, in the compression device, the extrusion mechanisms located at the front and rear sides of the body are relatively inclined, that is, the distance between the two extrusion mechanisms gradually decreases in the conveying direction of the reed stems, so as to reduce the output space and self-compress the material in the width direction during conveying, thereby reducing the setting of the power mechanism and reducing the overall complexity.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides a detailed implementation method.

[0035] The reed baler described in the present invention can be applied to the compression and baling of any pole-shaped crops, and is not limited to the use of reed poles. The present invention is only described by taking reed as an example.

[0036] Example 1

[0037] A fully automatic reed baler described in this embodiment includes a self-propelled chassis 1 with an engine system and a control system, that is, the self-propelled chassis 1 is the walking mechanism of the baler, and a driving cabin with a control system and a mounting frame 101 for installing various functional components are arranged on the walking chassis 1, and the user can drive the baler to move and adjust the operation of various systems in the driving cabin; the baler described in the present invention is also arranged on the chassis 1 and a feeding device 2, a conveying device 3, a shearing device 5, a compression device 7 and a baling device are arranged in sequence front and back, and at the same time, a pre-compression conveying mechanism 4 is provided on the feeding device 2 and the shearing device 5, so that the initial compression can be performed during the conveying process of the reed rods; a drop bin 6 is provided between the shearing device 5 and the compression device 7, and the setting of the drop bin 6 not only serves as an intermediate transition mechanism, but also the drop bin 6 lowers the upstream reed rods from a high place to a low place, thereby compressing the height of the whole machine and improving the coordination of the whole baler.

[0038] The feeding device 2 described in the present invention is located at the front end of the whole machine. In the working state, its working position is at the harvested reed stack. The feeding device 2 is driven to rotate by a driving motor, and is provided with a claw 205 that can be relatively extended and retracted during the rotation process to realize the claw 205 to move, transport and automatically release the reed stems. The specific structure is as follows: the feeding device 2 comprises a hollow roller body 201, a half shaft 202 located in the roller body 201, an eccentric shaft 203 and a pusher claw 205, wherein the roller body 201 is provided with a plurality of through holes; the half shaft 202 and the eccentric shaft 203 are both provided with a plurality of half shafts 202 and a plurality of eccentric shafts 203, and the half shafts 202 and the eccentric shafts 203 are arranged alternately, each half shaft 202 is arranged coaxially relative to the roller body 201, each eccentric shaft 203 is arranged eccentrically relative to the half shaft 202, and a pusher claw 205 is sleeved on the eccentric shaft 203, one end of the pusher claw 205 is provided with a sleeve 204 and is rotatably sleeved on the eccentric shaft 203 through a bearing, and the other end passes through the through hole on the surface of the roller body 201 and is free to move. The drive mechanism is provided with a transmission rod 206 connected to the power output shaft, one end of the transmission rod 206 is arranged in the roller body 201 and fixedly connected to the inner side of the roller body 201, the transmission rod 206 is a disc-shaped structure, and a groove is provided in the center thereof, and a bearing is arranged on the outer sleeve of the half shaft 202 at the end portion and arranged in the groove, so that the driving mechanism can smoothly drive the roller body 201 to rotate. At the same time, the rotation of the roller body 201 will drive the pusher claw 205 to be forced to move synchronously with the roller body 201, and at the same time, because the pusher claw 205 is arranged on the eccentric shaft 203, in the process of the pusher claw 205 rotating with the eccentric shaft 203 as the center, the pusher claw 205 is relatively extended and retracted relative to the roller body 201. Specifically, in the working state, when the pusher claw 205 rotates to the position where the corresponding eccentric shaft 203 is closest to the inner side of the roller body 201, the length of the pusher claw 205 exposed outside the roller body 201 is the longest, and the reed rod can be grabbed and moved; when the pusher claw 205 rotates to the position where the corresponding eccentric shaft 203 is farthest from the inner side of the roller body 201, the length of the pusher claw 205 exposed outside the roller body 201 is the shortest, which can be set to the free end of the pusher claw 205 just exposed from the roller body 201 at this time, and the reed rod that has been grabbed and moved can be released in this state. Under this functional requirement, each pusher claw 205 on the eccentric shaft 203 has a plurality of the same length, and the length of each pusher claw 205 is greater than the maximum distance from the semi-shaft 202 to the inner side of the roller body 201.

[0039] The feed port of the conveying device 3 opens upward to receive the material discharged by the feeding device 2. To adapt to the conveying device 3, the material-discharging device is located above the feed port of the conveying device 3. The roller body 201 of the material-discharging device rotates in the counterclockwise direction, that is, during the counterclockwise rotation, the length of the finger 205 exposed outside the roller body 201 is the smallest when it is at the closest position to the feed port of the conveying device 3, and then during the rotation, the exposed length of the finger 205 slowly increases until its exposed length at the opposite side of the roller body 201 is the largest, and the rotation continues, and the exposed length gradually decreases, forming a whole cycle in sequence.

[0040] The discharge port end of the conveying device 3 is rotatably connected to the mounting frame 101, and a first hydraulic cylinder 301 is provided in the middle of the conveying device 3, and the other end of the first hydraulic cylinder 301 is fixed on the chassis 1. The setting of the first hydraulic cylinder 301 enables the feed port end of the conveying device 3 to move up and down, so as to adjust according to the height of different reed rods, and ensure sufficient feeding to the feeding device 2. A material shifting chain driven by a driving motor is provided in the conveying device 3, and shifting teeth can be provided on the outer side of the material shifting chain and the material shifting chain is made of metal. The metal material material shifting chain can compress the reed rods to be docile during the conveying process, that is, a preliminary compression effect is achieved.

[0041] The pre-pressing conveying mechanism 4 is arranged at the discharge port of the conveying device 3, and the feed port of the pre-pressing conveying mechanism 4 receives the reed stems output from the conveying device 3. The pre-pressing conveying mechanism 4 includes two rollers 401 arranged opposite to each other up and down, each roller 401 extends along the conveying direction of the material, and the distance between the two rollers 401 decreases successively along the conveying direction; each roller 401 can be provided with a conveyor belt 402 driven by a driving motor, and each conveyor belt 402 is installed along the roller 401. The pre-pressing conveying mechanism 4 reduces the height of the conveying channel of the reed stems, and during the conveying process of its transmission belt, it pushes the reed stems to be compressed, and plays the function of pre-compression and flattening to prepare for subsequent shearing.

[0042] The shearing device 5 includes a cutting frame and a translation frame which are arranged perpendicularly to each other, wherein the cutting frame is arranged at the end of the translation frame away from the conveying device 3, i.e., the downstream end of the translation frame. A slideway with rollers is arranged below the translation frame and is slidably mounted on a mounting frame 101 with a guide rail. The pre-pressing conveying mechanism 4 is fixed integrally with the translation frame and is adjusted through the mounting frame 101 to the point where the pre-pressing conveying mechanism 4 can receive the material conveyed from the conveying device 3; a second hydraulic cylinder 502 is arranged in the translation frame to drive the shearing device 5 to slide, and the two ends of the second hydraulic cylinder 502 are respectively fixed on the mounting frame 101 and the translation frame; the second hydraulic cylinder 502 is controlled by a circuit to drive the shearing device 5 to reciprocate in the conveying direction.

[0043] The cutting frame includes a frame body 501, a moving knife mechanism movably mounted on the frame body 501, a fixed knife mechanism fixed to the bottom of the frame body 501, and a synchronizing device used in conjunction with the moving knife mechanism, wherein the moving knife mechanism includes a third hydraulic cylinder 503 that provides power and is fixed to the frame, a moving knife holder arranged at the movable end of the third hydraulic cylinder 503, and a moving blade 504 detachably mounted on the moving knife holder; the point hydraulic cylinder moves up and down to drive the moving blade 504 to move toward the fixed blade 505, and at the same time, the moving blade 504 is arranged tangent to the fixed blade 505 to ensure the cutting function. The synchronization device includes a rack 508 fixed on the moving blade holder and extending along the movement direction of the moving blade 504, a balance shaft 507 fixed on the frame 501, and a gear 506 rotatably sleeved on the balance shaft 507 through a bearing. During the movement of the moving blade 504, the gear 506 and the rack 508 are always meshed with each other to ensure that both ends of the moving blade 504 move synchronously; the lower side surface of the moving blade 504 is serrated, and the tooth surface of each sawtooth is inclined toward the side of the moving blade 504 through the formation of a blade edge and extends to the root of the sawtooth, and adjacent sawtooths are 5-10cm apart; the fixed blade mechanism includes a fixed blade seat and a fixed blade 505 detachably mounted on the fixed blade seat. The cutting device in the present invention can be slidably arranged, that is, the pre-pressing and conveying mechanism 4 and the shearing device 5 make reciprocating motion in the horizontal direction on the frame. When the reed rod is conveyed from the pre-pressing and conveying mechanism 4 to the shearing device 5, the movable blade 504 and the fixed blade 505 are in a separated state. While the system is moving, the movable blade 504 is driven by the third hydraulic cylinder 503 to make reciprocating motion in the up and down directions toward the fixed blade 505. When the second hydraulic cylinder 502 is in an extended state, that is, the shearing device 5 moves to a position deviating from its initial position, the shearing device 5 cuts the reed rod. At the same time, the second hydraulic cylinder 502 contracts, driving the shearing device 5 to return to its original position and prepare for the next cutting. In this state, the cut reed rod just falls into the drop bin 6 arranged downstream thereof. At the same time, due to the continuous output of the reed rod, the forward and backward displacement of the shearing device 5 just compensates for the forward displacement of the reed rod in the cutting state, thereby avoiding blockage caused by the continuous output of the reed rod during shearing.

[0044] The drop bin 6 is a bin structure without end faces, and its upper side surface can be set at the horizontal position of the moving blade 504 of the shearing device 5. The middle part of the bin body sinks to transfer the subsequent workpieces to the height of the chassis 1 of the whole machine, so as to compress the height of the whole machine and improve the coordination of the whole baler. The upper side surface of the drop bin 6 is a bin door structure that opens inwards. An elastic spring can be set on the bin door to pull the bin door closed. When the cut reed stems fall on the bin door, the bin door automatically opens due to the weight, and the reed stems fall into the bin. A fourth hydraulic cylinder is set at the end face of the drop bin 6 close to one end of the conveying device 3. The piston rod of the fourth hydraulic cylinder is connected to a push plate, and the push plate reciprocates along the end face direction of the drop bin 6 to push the accumulated materials in the bin into the compression device 7. An electronic metering device is provided in the drop bin 6, and the electronic metering device is connected to the central processing unit of the whole machine by a circuit. According to the parameter setting, when the reed rods reach the specified weight, the fourth hydraulic cylinder works to push the reed rods in the bin into the compression device 7, so as to achieve uniform weight of each packaged reed rod and meet customer needs.

[0045] The compression device 7 receives the material pushed up horizontally from the material drop bin 6. The compression device 7 includes a body and an extrusion mechanism arranged on the side of the body. There are four extrusion mechanisms, which are respectively arranged on four sides adjacent to the feed port of the body. The extrusion mechanisms located on the upper side and rear side of the body are slidably arranged with the body, and are respectively provided with power mechanisms to drive the extrusion mechanisms 703 to reciprocate. The power mechanism here in the present invention can be a hydraulic cylinder, that is, the power mechanism located on the upper side of the body connected to the extrusion mechanism here is the baling vertical pressure cylinder 701, and the power mechanism located on the rear side of the body connected to the extrusion mechanism here is the baling horizontal pressure cylinder 702. Through the movement of the baling vertical pressure cylinder 701 and the baling horizontal pressure cylinder 702, the reed rods in the body are compressed in the height direction and the width direction. The extrusion mechanism includes a roller group 704, a conveyor belt 705 wrapped around the roller group 704, and a driving motor that provides power to the roller group 704 and the conveyor belt 705, wherein the driving motor drives the roller located at one end of the roller group 704 through gears; the side surfaces of the rollers in the roller group 704 are all provided with driving teeth, and the inner side surface of the conveyor belt 705 is provided with a toothed belt used in conjunction with the driving teeth; the compression device 7 in the present invention adopts an integrated structure of conveying and compression, and the conveying mechanism composed of the roller group 704, the conveyor belt 705 and the driving motor also serves as an extrusion mechanism. At the same time, the driving motor that drives the roller group 704, the packing vertical pressure cylinder 701 and the packing horizontal pressure cylinder 702 are all connected to the central processing unit through a circuit, and the three can be controlled to work synchronously or asynchronously. At the same time, a tightening mechanism 706 consisting of a tightening wheel and a support arm is arranged on the outside of the conveyor belt 705 of each extrusion mechanism. The tightening mechanism 706 tightens the extrusion mechanism by compressing the conveyor belt 705 to ensure its conveying function. At the same time, the tensioned conveyor belt 705 can better support the material stress.

[0046] The arrangement of this mechanism integrates the compression device 7 and the conveying device 3 into one, which greatly reduces the working efficiency compared with the existing split structure. At the same time, the packaging device is followed closely after the compression output to ensure the compression effect. A strapping machine is arranged on the downstream side of the compression device 7 as a packaging device to quickly package the compressed reed stalks. So far, the baler described in the present invention shears, compresses and packages the piled and randomly piled reed stalks, and completes the entire work process with high automation.

[0047] Example 2

[0048] The specific structure of the fully automatic reed baler described in this embodiment is basically the same as the specific structure of the fully automatic reed baler described in Example 1, with the difference being that the power mechanism may only be provided with a baling vertical pressure cylinder 701, and the extrusion mechanisms located at the front and rear sides of the compartment are relatively inclined, that is, the distance between the two extrusion mechanisms gradually decreases in the conveying direction of the reed rods, so as to reduce the output space and perform self-compression on the material during conveying in the width direction, thereby reducing the setting of the power mechanism and reducing the overall complexity.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
