Abstract
Description
Technical Field
[0001] This disclosure generally relates to the field of agricultural machinery and equipment technology. More specifically, this disclosure relates to a hay bale machine. Background Technology
[0002] As a key piece of equipment in agricultural production for processing straw and preparing feed, the straw block machine's core function is to transform straw into feed that meets animal consumption standards through processes such as picking, conveying, and cutting. It plays a vital role in improving the resource utilization rate of straw and reducing breeding costs. The basic structure of existing straw block machines typically includes a picking device (containing rollers and radially arranged picking teeth), a conveying device, a chaff cutter, a baling device, a cab, and a wheel axle system. The wheel axle system follows the traditional agricultural machinery design logic of front axle steering and rear axle drive; that is, the front axle is equipped with steering wheels for overall machine steering, while the rear axle is equipped with drive wheels for heavy-duty drive.
[0003] Current general-purpose chassis typically employ a front light axle steering and a rear heavy axle drive without steering. Integrating existing automated hay-collecting mechanisms with this type of chassis would lead to severe overload on the front light axle due to excessive weight, potentially causing tire blowouts, bearing and axle failure due to insufficient load, and steering mechanism malfunction or damage from overload. On the other hand, the rear heavy axle, as the drive axle, suffers from an unbalanced weight distribution, resulting in a lighter actual load. This makes it prone to tire slippage and brake failure when operating on wet or soft ground, ultimately causing an imbalance in the vehicle's front-rear weight distribution and preventing normal movement.
[0004] In view of this, there is an urgent need to provide a solution for a grass block machine to optimize the overall weight distribution and avoid the problems of tire blowouts and steering failure caused by heavy loads on the front light axle, and slippage during operation caused by light loads on the rear heavy axle. Utility Model Content
[0005] In order to at least address one or more of the technical problems mentioned above, this disclosure proposes a solution for a grass block machine in several aspects.
[0006] This disclosure provides a hay bale machine, comprising: a pickup system disposed at the front end of the chassis along its length; a front axle mounted at the front end of the chassis and close to the pickup system; the front axle is mounted by rotating 180 degrees about the centerline along the chassis length, so that the original rear axle is used as the front axle, and the front axle serves as the drive axle; two load-bearing wheels are respectively disposed on both sides of the front axle; a rear axle is mounted at the rear end of the chassis, below the engine, and the rear axle serves as the steering axle; one load-bearing wheel is respectively disposed on both sides of the rear axle; a cab is mounted above the front axle; the driving direction of the hay bale machine is towards the direction of the pickup system.
[0007] In some embodiments, the length between the center points of the front axle and the rear axle is 3m-3.5m.
[0008] In some embodiments, the chassis is provided with a transfer case, which is connected to the front axle via a front axle drive shaft and is used to reduce the traveling speed of the grass block machine and to control the angular velocities of the front and rear axles to be equal.
[0009] In some embodiments, the chassis is equipped with a gearbox, which is connected to the transfer case via a drive shaft.
[0010] In some embodiments, the grass block machine employs a pneumatic clutch system, which includes: a clutch master pump; and an air tank mounted on the outer side wall of the chassis; the air tank is connected to the clutch master pump via a first connecting pipe, and the clutch master pump is connected to a brake via a second connecting pipe.
[0011] In some embodiments, the braking stroke of the pneumatic clutch system is not less than 6 centimeters.
[0012] In some embodiments, the pneumatic clutch system is integrated with the gearbox and located at the position of the rear axle.
[0013] In some embodiments, the hay block machine further includes a hay pressing system disposed on the chassis between the cab and the rear axle.
[0014] In some embodiments, the picking system includes a picking device, a conveying device, and a guillotine device.
[0015] In some embodiments, the front axle includes a differential.
[0016] By designing the front axle near the picking system as a drive axle that is rotated 180 degrees from the original rear axle around the centerline of the chassis length, and by designing the original rear axle as the front axle, the present embodiment of the grass block machine can effectively solve the problem of unbalanced weight distribution in the existing grass block machine, which is light in the front and heavy in the rear. This avoids the problem of tire slippage and power transmission loss caused by the original rear axle (original drive axle) being lightly loaded, which makes it unable to move stably, as well as the problem of tire blowout and steering failure caused by the original front axle (original steering axle) being heavily loaded.

[0027] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.
[0028] like Figure 1 As shown, the original front axle 103-1 of the existing sod block machine is a steering axle, and the original rear axle 104-1 is a drive axle. The direction of travel of the sod block machine is along the extension direction from the original rear axle 104-1 to the original front axle 103-1. Since the existing solution has the problems mentioned in the background art, this application provides a new sod block machine.
[0029] like Figure 2 and Figure 3 As shown, in some embodiments, this application provides a hay bale machine 100, including: a pickup system 101, which is disposed at the front end of a chassis 102 along its length; a front axle 103, which is mounted at the front end of the chassis 102 and disposed close to the pickup system 101; the front axle 103 is mounted by rotating 180 degrees about the centerline of the chassis 102 along its length, so that the original rear axle is used as the front axle 103, and the front axle 103 serves as a drive axle; two load-bearing wheels are respectively disposed on both sides of the front axle 103; a rear axle 104, which is mounted at the rear end of the chassis 102, below the engine, and the rear axle 104 serves as a steering axle; one load-bearing wheel is respectively disposed on both sides of the rear axle 104; a cab 105, which is mounted above the front axle 103; the driving direction of the hay bale machine 100 is towards the direction of the pickup system 101.
[0030] The straw block harvester 100 provided in this application includes a picking system 101, a front axle 103, a rear axle 104, and a cab 105. Specifically, the picking system 101 is located at one end of the chassis 102 along its length and includes a picking device, a conveying device, and a chaff cutter 110, serving as the core operating component for straw picking, conveying, and preliminary cutting. The front axle 103 (referring to the original rear axle in the prior art) is mounted on the chassis 102 and close to the picking system 101, and is assembled by rotating it 180 degrees about the centerline along the length of the chassis 102. This mounting method allows the front axle 103 to serve as a drive axle to meet heavy-duty operation requirements. Due to the change in the overall vehicle layout, the gearbox 108 is now located at the rear of the chassis 102, allowing the input shaft of the front axle 103 to face the output shaft of the gearbox 108 located behind it after rotation. This installation method, without altering the internal gear meshing relationship of the front axle 103, achieves matching of the rotation direction of its input shaft with that of the output shaft of the gearbox 108. This allows the front axle 103 to function as a drive axle to meet heavy-duty operation requirements, eliminating the need for a reverse gearbox, significantly simplifying the equipment structure and reducing manufacturing costs. Additionally, two load-bearing wheels are installed on each side of the front axle 103 to improve traffic safety under heavy-duty conditions. The rear axle 104 is mounted on the chassis 102 at a suitable position relative to the picking system 101. Specifically, the rear axle 104 is installed at the rear end of the chassis 102, below the traveling engine, and functions as a steering axle to assist the front axle 103 in achieving overall machine steering. One load-bearing wheel is installed on each side. The cab 105 is mounted above the front axle 103, with the driving direction of the hay block machine 100 facing the direction of the picking system 101, facilitating real-time observation of the picking operation status by the driver and optimizing operational convenience and accuracy.
[0031] The hay block maker 100 provided in this application differs from the traditional hay block maker 100's front-steering and rear-drive design. It adopts an innovative front-drive, rear-steering layout, solving the problem of unbalanced weight distribution. This avoids the predicaments of existing technologies where the front-mounted pickup system cannot perform field work, and the original rear axle 104-1 is unable to exert force under light loads, while the original front axle 103-1 is prone to tire explosions and steering failure under heavy loads, resulting in malfunctions. Furthermore, the solution in this application, with two load-bearing wheels on each side of the front axle 103 and one load-bearing wheel on each side of the rear axle 104, ensures both driving stability for heavy-load field operations and steering flexibility, meeting the practical needs of efficient pickup and stable movement in the field.
[0032] In one specific implementation, the length between the center points of the front axle 103 and the rear axle 104 is 3m-3.5m.
[0033] In this application, the length between the center points of the front axle 103 and the rear axle 104 is set to 3m-3.5m. Based on the layout where heavy components such as the cab 105 and the pickup system 101 are located at the front of the chassis 102, this specific wheelbase range effectively balances the machine's center of gravity and increases anti-pitch moment, thereby ensuring that the hay bale harvester 100 maintains excellent stability and maneuverability during heavy-load operations, meeting the needs of efficient field pickup operations.
[0034] In one specific implementation, a transfer case 106 is provided on the chassis 102. The transfer case 106 is connected to the front axle 103 via the front axle drive shaft 107 and is used to reduce the travel speed of the grass block machine 100 and to control the angular velocities of the front axle and the rear axle to be equal.
[0035] In this application, to ensure the hay block maker 100 accurately adapts to the rhythm of straw picking in the field, a transfer case 106 is also provided on the chassis 102. The input end of the transfer case 106 is connected to the gearbox 108, and the output end is connected to the front axle 103 via the front axle drive shaft 107. The core function of the transfer case 106 is to provide an additional deceleration gear, obtain the same angular velocity as the front and rear axles, and enable the hay block maker 100 to obtain a low-speed mode that is suitable for agricultural machinery field operation scenarios. This solution effectively avoids problems such as incomplete straw picking and discontinuous operation process caused by excessively high gear speeds in the basic gearbox 108, ensuring that the vehicle can travel stably at low speed, allowing sufficient time for the picking system 101 to complete the picking, conveying, and preliminary cutting of straw, thereby fundamentally guaranteeing overall operation efficiency and feed quality.
[0036] In one specific implementation, a gearbox 108 is provided on the chassis 102, and the gearbox 108 is connected to the transfer case 106 via a drive shaft 109.
[0037] In this application, a gearbox 108 is also provided on the chassis 102, and the gearbox 108 is connected to the transfer case 106 via a drive shaft 109. In the power transmission chain, the gearbox 108 mainly provides multiple operating gears (such as five forward gears and one reverse gear) to adapt to the needs of different working conditions and transmits power to the transfer case 106. As a key speed reduction module, the transfer case 106 performs the final low-speed ratio conversion on the received power to ensure that the speed output to the front axle 103 meets the requirements of low-speed, heavy-load operation.
[0038] In use, the operator can first select the basic gear through the gearbox 108 according to the actual conditions such as straw density and field terrain, and then switch to the low-speed mode through the transfer case 106, thereby achieving flexible and precise control of the travel speed. This collaborative working mode effectively avoids incomplete picking due to excessive speed or low work efficiency due to speed mismatch, fully ensuring that the picking system 101 (including the picking device, conveying device, and chaff cutter device 110) can stably and efficiently complete straw processing, and fully meet the needs of efficient and heavy-duty operations in agricultural fields.
[0039] In one specific implementation, the grass block machine 100 employs a pneumatic clutch system, which includes: a clutch master cylinder; and an air tank mounted on the outer wall of the chassis 102. The air tank is connected to the clutch master cylinder via a first connecting pipe, and the clutch master cylinder is connected to the brake via a second connecting pipe. The braking stroke of the pneumatic clutch system is not less than 6 centimeters.
[0040] In this application, the grass block machine 100 uses a pneumatic clutch system, which specifically includes a clutch master pump and an air tank. The air tank is installed on the outer side wall of the chassis 102, and the two are connected through a first connecting pipe. At the same time, the clutch master pump is connected to the clutch actuator through a second connecting pipe, forming a complete pneumatic clutch operation path. In addition, the disengagement stroke of this pneumatic clutch system is not less than 6 centimeters.
[0041] The proposed solution utilizes the long stroke and fast response characteristics of compressed air to ensure complete clutch disengagement and smooth engagement. This solution eliminates the need for complex hydraulic circuits and oil storage devices, simplifying the structure and reducing maintenance costs while significantly improving the reliability of power transmission, smoothness of gear shifting, and operational safety of the hay bale machine 100 under heavy-duty field operations.
[0042] In one specific implementation, the pneumatic clutch system is integrated with the gearbox 108 and located at the location of the rear axle 104.
[0043] In this application, the pneumatic clutch system and gearbox 108 are integrated, and this integrated assembly is located at the rear axle 104. This integrated design significantly shortens the operation and power transmission path between the pneumatic clutch system and gearbox 108, improves response efficiency, and reduces potential failure points in the intermediate links. Furthermore, the rear axle 104 area serves as a stable mounting base on the chassis 102 and is far from the high-speed rotating, easily entangled straw-collecting system 101 at the front, providing the integrated clutch and gearbox 108 assembly with a cleaner and safer working environment that is minimally affected by operational interference. In other words, this arrangement effectively ensures the reliability and smoothness of power engagement and transmission, significantly adapting to the heavy-duty, high-efficiency field operation requirements of the hay bale machine 100.
[0044] In one specific implementation, the hay block machine 100 also includes a hay pressing system disposed on the chassis 102 between the cab 105 and the rear axle 104.
[0045] The straw block machine 100 provided in this application is also equipped with a straw pressing system, which is specifically arranged on the chassis 102 between the cab 105 and the rear axle 104. From a structural adaptability perspective, combined with the previous wheelbase design of 3m-3.5m between the center points of the front axle 103 and the rear axle 104, the space between the cab 105 and the rear axle 104 can fully accommodate the straw pressing system. This avoids layout conflicts with the front-end picking system 101 and the cab 105 above, and also avoids interference with the pneumatic clutch system and gearbox 108 integrated at the rear axle 104. From an operational perspective, this location allows the straw pressing system to work seamlessly with the front-end picking system 101. That is, after the picking system 101 completes straw picking and conveying, the straw can directly enter the subsequent straw pressing system for pressing and shaping, forming a natural and continuous material conveying path that does not require complex steering. This layout effectively overcomes the problem of poor process connection caused by the scattered component layout of the traditional straw block machine 100, and further improves the overall operation efficiency of straw from picking up to pressing into shape.
[0046] In one specific implementation, the picking system 101 includes a picking device, a conveying device, and a guillotine device 110.
[0047] The picking system 101 of this application includes a picking device, a conveying device, and a chaff cutter device 110. Specifically, the picking device includes a support plate with an arc-shaped upper surface, a picker with a rotating shaft and picking teeth, and a vertical tooth picking assembly disposed above the support plate. The picker is used to pick up materials from the field onto the support plate, and then the vertical tooth picking assembly further transfers the straw on the support plate to the conveying device. The conveying device consists of a conveyor belt and several spiral assemblies spaced apart along the length of the conveyor belt, which can not only realize the continuous conveying of straw, but also distribute the straw evenly in the width direction of the conveyor belt through the spiral assemblies, preventing accumulation and blockage. The chaff cutter device 110 is used to cut the straw into lengths that meet the requirements of feed processing, laying the foundation for the subsequent briquetting process.
[0048] In one specific implementation, the front axle 103 includes a differential.
[0049] In the solution of this application, to ensure the steering flexibility of the hay block machine 100 during field operations and to adapt to the adjustment requirements of the working path of the picking system 101, a differential is integrated into the front axle 103, which serves as the drive axle. Specifically, the core function of this differential is to realize the differential action during steering, that is, when the hay block machine 100 needs to turn, it can automatically distribute the speed of the left and right drive wheels (for example, allowing the outer wheel to turn faster than the inner wheel), thereby forming a smooth steering action and avoiding wheel slippage.
[0050] This setting allows the hay bale machine 100 to adjust its direction flexibly and precisely when moving in the field, ensuring that the picking device can effectively cover and catch the scattered straw, avoiding the problem of missed picking due to clumsy or unresponsive turning, and further improving the overall operating efficiency and terrain adaptability.

Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of this disclosure.
