Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a rotary transfer type self-propelled pickup and palletizing integrated machine. Background Technology

[0002] With the continuous deepening of agricultural scale and intensification, the level of mechanization and automation in agricultural production has significantly improved. In the post-harvest processing of crop straw or forage, mechanized operations for picking up and stacking straw / straw bales have become the mainstream trend. This model uses specialized mechanical systems to automatically complete the entire process of picking up, collecting, transferring, and even stacking straw / straw bales that have already been formed in the field, replacing the heavy and inefficient manual picking and stacking labor of the past.

[0003] However, the mainstream picking equipment (pickers / pickers) currently widely used in straw / bale picking operations still have significant technical bottlenecks and functional defects in terms of performance and adaptability, which urgently need optimization and improvement. Specifically, existing straw / bale picking machines generally use exposed, rigid chain drive mechanisms as the core lifting and conveying components, which directly leads to the core problems of severe damage to the integrity of straw / bale and high material loss rate during operation. In the process of picking up and lifting easily scattered materials such as straw / bale, the hard chain links, chain plates, or scrapers inevitably have direct and violent friction and scraping with the surface of the straw / bale. This rough contact method causes multiple serious consequences: First, it causes a large amount of grass leaves and debris to fall off and be lost during transportation; second, the edges or sharp parts of the chain are very easy to cut, wear, or snag the ropes (hemp rope, plastic rope, etc.) of the straw / bale, posing an extremely high risk of rope cutting and breakage; once the rope is cut or severely worn, the straw / bale will lose its restraint and completely disintegrate during transportation.

[0004] The aforementioned damage mechanisms work together to keep the loss rate of straw / hay bales during operations consistently high. This not only significantly reduces the effective collection volume and economic benefits of crop straw or forage, but also adds to the burden of subsequent field cleanup. Furthermore, bale collection and transportation are mostly segmented operations, reliant on manual labor, and involve high labor intensity.

[0005] Therefore, a rotary transfer self-propelled pickup and palletizing integrated machine is provided to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary transfer self-propelled pickup and palletizing integrated machine to solve the problems existing in the prior art. It can effectively reduce the damage rate of straw bales / straw bales and the risk of rope wear, and can realize continuous pickup, stable transportation and automatic stacking of straw bales / straw bales, thereby improving work efficiency.

[0007] To achieve the above objectives, the present invention provides the following solution: This invention provides a rotary transfer self-propelled pickup and palletizing integrated machine, including a machine body, a pickup device, and a multi-stage bundling platform.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The purpose of this invention is to provide a rotary transfer self-propelled pickup and palletizing integrated machine to solve the problems existing in the prior art. It can effectively reduce the damage rate of straw bales / straw bales and the risk of rope wear, and can realize continuous pickup, stable transportation and automatic stacking of straw bales / straw bales, thereby improving work efficiency.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 like Figures 1-7As shown, this embodiment provides a rotary transfer self-propelled pickup and palletizing integrated machine, mainly including a machine body, a pickup device 6, and a multi-stage bundling platform. The front end of the machine body is equipped with a driver's cab 1, and the bottom of the machine body is equipped with a driving system 5, which can drive the machine body to move. The pickup device 6 is located at the front of the machine body and includes a pickup arm 601 and a rotary transfer conveying mechanism. The pickup arm 601 is used to guide the material bundles to be conveyed backward, and the rotary transfer conveying mechanism includes multiple rotating rollers 606. The rotating rollers 606 are spirally distributed upwards, and both ends of the rotating rollers 606 are rotatably mounted on a rotating support. One of the rotating rollers 606 is connected to a material bundle conveying power device, and the multiple rotating rollers 606 are connected by a conveyor belt 607. The material bundle conveying power device can drive the multiple rotating rollers 606 to rotate, thereby driving the spiral transfer and conveying of the material bundles. The top of the rotating transfer and conveying mechanism is connected to the multi-level bundling platform, which can flip and transfer the material bundles to achieve automatic layered stacking.

[0026] The rotary transfer conveying mechanism described in this embodiment uses a rotary roller 606 to convey the material bundles, which can effectively reduce the breakage rate of the material bundles and the risk of rope wear, and significantly improve the integrity of the material bundles and the conveying efficiency. Moreover, this embodiment integrates a picking device 6 and a multi-level bundling platform on the main body of the machine, which can realize continuous picking, stable conveying and automatic stacking of material bundles, thereby improving work efficiency.

[0027] Furthermore, it should be noted that the bale can be a straw bale or a grass bale, etc.

[0028] In this embodiment, the rear end of the picking arm 601 is also provided with a picking shovel 609. The upper surface of the picking shovel 609 has an arc-shaped structure, which is used to support and smoothly push the straw bales / grass bales.

[0029] In this embodiment, a guiding mechanism is further provided between the picking arm 601 and the rotary transfer conveying mechanism. The guiding mechanism forms a guiding channel for guiding the conveying of straw bales / bales. A conveying chain 605 is provided at the guiding channel. The conveying chain 605 is connected to the bale conveying power device and is drively connected to one of the rotating rollers 606. The bale conveying power device can drive the conveying chain 605 to rotate to convey the straw bales / bales, and simultaneously drive the rotating roller 606 to rotate. The bale conveying power device can be selected according to specific working needs; for example, a bale conveying motor 7001 can be selected.

[0030] Traditional picking mechanisms typically rely solely on chain conveyors, resulting in a single operating mode. When the picking speed is too fast, the straw / bundles may become stuck in the picking mechanism. Additionally, the bale collection platform needs to be stopped when it flips, allowing for a buffer period and preventing continuous operation. In contrast, the picking device 6 in this embodiment uses a combination of a conveyor chain 605 and a rotating roller 606 to spirally convey the straw / bundles, providing space for them to remain in place. This allows for continuous operation without stopping the machine and reduces the likelihood of damage to the straw / bundles.

[0031] In this embodiment, the guiding mechanism includes an upper stop bar 603, a lifting plate 602, a side baffle 608, and a guide rod 604. The two sides of the picking arm 601 are respectively connected to the rotating supports on both sides via the side baffle 608. The upper stop bar 603 is disposed at the top of the picking arm 601 and extends along the width direction of the picking arm 601. The front end of the lifting plate 602 is rotatably connected to the upper stop bar 603, and its rear end is welded to the front end of the guide rod 604. The rear end of the guide rod 604 is slidably disposed on a rotating support. A guiding channel is formed between the guide rod 604 and the side baffle 608. When the straw bale / straw bale is pushed and contacts the lifting plate 602, the straw bale / straw bale applies an upward pushing force to the lifting plate 602, causing the lifting plate 602 to lift around the upper stop bar 603 and driving the guide rod 604 to lift as a whole, thereby achieving two key effects: Increased guide gap: After the guide rod 604 is raised, the vertical distance between it and the side baffle 608 is significantly increased, so that straw bales of different sizes or slightly deformed bales can enter the guide channel smoothly, avoiding jamming or squeezing caused by insufficient space. Constructing a dynamic guide channel: The raised guide rod 604 cooperates with the rigid side baffles 608 on both sides of the equipment to form an automatically adjustable guide channel, which effectively limits the deviation of straw bales / grass bales and achieves stable and accurate feeding.

[0032] Under the guidance of the guiding mechanism, the straw bales / straw bales enter the conveying mechanism driven by the conveying chain 605 in a stable posture. The conveying chain 605 runs continuously, smoothly feeding the straw bales / straw bales into the rotating roller 606. The surface of the rotating roller 606 is provided with an anti-slip protrusion structure, which on the one hand enhances the friction driving force with the straw bales / straw bales and prevents them from slipping on the roller surface; on the other hand, it realizes the effective transfer of the straw bales / straw bales, so that they can smoothly enter the subsequent rotating transfer conveying section.

[0033] After the straw bales / straw bales enter the conveying system consisting of the rotating roller 606 and the conveyor belt 607, the rotating roller 606 is driven to rotate by the rotation of the conveyor belt 607, so that the straw bales / straw bales are smoothly transferred along the spiral path and finally sent to the multi-level bale collection platform for stacking preparation.

[0034] In this embodiment, a flexible linkage structure of lifting plate 602 and guide rod 604 is adopted, which can automatically adjust the infeed gap according to the size of straw / bundle, avoiding the problem of easy jamming in traditional fixed guide structures. The tail of guide rod 604 is slidably connected to rotating roller 606, realizing dynamic coupling of feeding and conveying, and improving the smoothness of feeding. The combination design of anti-slip rotating roller 606 and conveying chain 605 effectively reduces the damage rate of straw / bundles and the risk of rope wear, significantly improving the integrity of straw / bundles and conveying efficiency.

[0035] In this embodiment, the picking device 6 is also connected to the main body of the machine via a picking device tilting cylinder 7002, which can drive the picking device 6 to rise and fall.

[0036] In this embodiment, the multi-level baling platform can be selected according to specific work needs. As an optional implementation, the multi-level baling platform may include a first-level baling platform 2, a second-level baling platform 3, and a third-level baling platform 4 connected in sequence. Each platform is driven by a hydraulic system to flip and transfer the straw bales / straw bales, thereby achieving automatic layered stacking.

[0037] In this embodiment, a transmission chain 205 is provided on one end of the primary baling platform 2 near the picking device 6. The transmission chain 205 is connected to a transmission motor, which drives the transmission chain 205 to rotate, so as to transport the straw bales / grass bales to the primary baling platform 2. The primary baling platform 2 is also connected to the machine body through a primary baling platform cylinder 7003, which can drive the primary baling platform 2 to rotate. The secondary bundling platform 3 is connected to the main body of the machine via a secondary bundling platform hydraulic cylinder 7004, which can drive the secondary bundling platform 3 to rotate. The three-stage bundling platform 4 is connected to the main body of the machine via a three-stage bundling platform hydraulic cylinder 7005, which can drive the three-stage bundling platform 4 to rotate.

[0038] In this embodiment, detection mechanisms are provided on the primary bundling platform 2, the secondary bundling platform 3, and the tertiary bundling platform 4. These detection mechanisms are used to detect whether the platform is fully loaded and are connected to the control system of the cab 1. When the detection mechanism detects full load, the control system controls the corresponding platform to tilt. The detection mechanism can be selected according to specific operational needs; for example, it can be a proximity switch.

[0039] In this embodiment, upright stops 407 are provided on both sides of the front end of the three-stage bundling platform 4, and a bundling fork 401 is provided between the tops of the upright stops 407 on both sides. The bundling fork 401 is connected to the upright stops 407 through a push rod cylinder 7006. The extension and retraction of the push rod cylinder 7006 drives the bundling fork 401 to rotate, so as to facilitate bundling. Guardrails 402 are also provided on both sides of the three-stage bundling platform 4. A fixed bundling fork 404 is provided at the rear end of the three-stage bundling platform 4. A slide rail 405 is also provided on the three-stage bundling platform 4 along its length direction. A sliding bundling fork 403 is slidably connected to the slide rail 405 through a sliding mechanism 406.

[0040] In this embodiment, when the primary baling platform 2 is fully loaded, the detection mechanism sends a signal, and the control system in the cab 1 controls the hydraulic system of the primary baling platform 2 to flip it and send the bales into the secondary baling platform 3. When the secondary baling platform 3 is fully loaded, it controls the secondary baling platform 3 to flip 90°. Initially, the sliding bale stop fork 403 is close to the upright stop bar 407. As the secondary baling platform 3 flips multiple times, the upright stop bar 407 and the sliding bale stop fork 403 work together to fix the bales and prevent the straw bales / bales from collapsing. When the sliding bale stop fork 403 slides to the last position, the full load signal is transmitted to the main control panel in the cab 1. The driver drives the vehicle back to the warehouse. After reaching the designated position, the driver controls the tertiary baling platform 4 to flip, and uses inertia to unload the straw bales / bales to the designated position.

[0041] In this embodiment, the hydraulic control system is as follows: Figure 7 As shown, its working principle is as follows: The material bundle conveyor motor 7001 is connected to the conveyor chain 605 to drive the conveyor chain 605 to move; one end of the picking device tilting cylinder 7002 is connected to the picking device 6 and the other end is connected to the machine body, and the lifting and lowering of the picking device 6 is controlled by extension and retraction; one end of the first-level bundling platform cylinder 7003 is connected to the first-level bundling platform 2 and the other end is connected to the machine body, and the automatic tilting of the first-level bundling platform 2 is controlled by extension and retraction; one end of the second-level bundling platform cylinder 7004 is connected to the second-level bundling platform 3 and the other end is connected to the machine body, and the automatic tilting of the second-level bundling platform 3 is controlled by extension and retraction; one end of the third-level bundling platform cylinder 7005 is connected to the third-level bundling platform 4 and the other end is connected to the machine body, and the automatic tilting of the third-level bundling platform 4 is controlled by extension and retraction; one end of the push rod cylinder 7006 is connected to the upright stop 407 and the other end is connected to the pressing fork 401, and the rotation of the pressing fork 401 is controlled by extension and retraction.

[0042] The oil tank 7014 is connected to the main body of the machine and stores hydraulic oil. The oil tank 7014 is connected to the medium-pressure pump 7011 and the high-pressure pump 7012 via a suction filter 7013. The suction filter 7013 prevents impurities from entering the hydraulic pumps. The medium-pressure pump 7011 and the high-pressure pump 7012 provide hydraulic oil at different pressures and flow rates to form a medium-pressure system and a high-pressure system, respectively. The first hydraulic gauge 7009 is connected to the medium-pressure pump 7011 to display the real-time working pressure of the medium-pressure system. The second hydraulic gauge 7010 is connected to the high-pressure pump 7012 to display the real-time working pressure of the high-pressure system. The first pilot-operated solenoid relief valve 7018 is connected to the medium-pressure pump 7011, and the second pilot-operated solenoid relief valve 7019 is connected to the high-pressure pump 7012. Both valves are used to set and limit the maximum working pressure of their respective systems. When the system pressure exceeds the set value, the relief valves open, returning excess oil to the oil tank 7014 to prevent system overload. The medium-pressure pump 7011 and the high-pressure pump 7012 are connected to each hydraulic cylinder through an electro-hydraulic directional valve 7007. The electro-hydraulic directional valve 7007 is installed on the main body of the machine and is used to control the flow of hydraulic oil to each actuator, thereby controlling its direction of action. The hydraulic lock 7008 is installed in the oil circuit of the hydraulic cylinder and can realize the locking of the oil circuit of the two chambers of the hydraulic cylinder.

[0043] The oil tank 7014 is also equipped with a level and temperature measuring instrument 7015, which is used to monitor the level and temperature of the hydraulic oil in the oil tank 7014; the oil tank 7014 is also connected to an air filter 7016, which is used to filter the air entering the oil tank 7014 and also serves as an oil filling port; the return oil filter 7017 is installed in the pipeline 7020 to filter the hydraulic oil flowing back to the oil tank 7014.
