Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a feeding device for a hay picking and baling machine. Background Technology

[0002] With the continuous improvement of the scale of animal husbandry, hay balers, as agricultural machinery used to achieve efficient hay recycling and baling, are increasingly widely used in grassland harvesting, forage storage and transportation, and other scenarios. Among them, the feeding device, as a crucial intermediate link connecting picking and baling, directly affects the continuity and efficiency of the entire baling operation system due to its operational stability.

[0003] Existing hay balers typically have a front pickup roller inside the frame to pick up hay from the ground and transport it to the rear baling mechanism via a conveyor. Some feeding mechanisms also include simple guide components to assist in hay transport. However, due to the loose and uneven distribution of hay, existing feeding mechanisms generally suffer from insufficient control over the flow path of the hay, especially in the section from pickup to baling, where hay is prone to shifting, piling up, or scattering, affecting baling continuity and bale quality.

[0004] Therefore, the current feeding device of hay picking and baling machines still lacks an effective hay flow guidance mechanism. It is necessary to improve the feeding device of existing hay picking and baling machines to improve operating efficiency. Utility Model Content

[0005] This application provides a feeding device for a hay picking and baling machine to solve the problem in the prior art that the lack of an effective flow guidance mechanism during the backward conveying of hay after picking up results in an uneven feeding path and poor concentration.

[0006] This application provides a feeding device for a hay picking and baling machine, comprising:

[0007] The housing includes left and right side panels and an upper cover, forming an internal feeding chamber;

[0008] A picking mechanism is located at the lower front of the housing. The picking mechanism includes a picking roller with multiple evenly distributed spring teeth for picking up hay from the ground.

[0009] A spiral conveying mechanism is located inside the housing near the rear of the picking mechanism. The spiral conveying mechanism includes a horizontally arranged spiral feeding roller that can gather the hay from both ends to the middle area. It is used to gather the hay and sort and propel the hay during rotation.

[0010] The beating and guiding device is located in the middle of the spiral feed roller and is used to loosen and beat the forage during transportation and guide the forage backward.

[0011] A conveyor belt mechanism is located at the rear of the housing. The conveyor belt mechanism includes a rotatable conveyor belt for conveying the collected hay for subsequent baling operations.

[0012] In one optional embodiment, the spring teeth have a Y-shaped plate structure and are rotatably mounted on multiple tooth seats on the outer circumferential surface of the pickup roller. The multiple spring teeth are arranged alternately on the pickup roller and can swing as the pickup roller rotates.

[0013] In one optional embodiment, the axis of the spiral feed roller is parallel to the transverse direction of the housing. Feeding spiral blades are respectively provided at both ends of the outer surface of the spiral feed roller along the axial direction. The feeding spiral blades at both ends are arranged in opposite spiral directions to gather the forage at both ends to the middle area of ​​the spiral feed roller and realize the sorting and advancement of the forage, so as to facilitate subsequent beating, guiding and conveying.

[0014] In one optional embodiment, a conveyor box is provided on the outside of the conveyor belt, the conveyor box is fixedly installed on the rear side of the housing, a conveying port communicating with the conveyor box is opened on the rear side plate of the housing, and the conveyor belt is provided with protruding friction strips.

[0015] In one optional embodiment, the tapping guide device includes a guide cover integrally formed with the housing and a tapping plate fixedly disposed in the middle section area of ​​the spiral feed roller. The guide cover is disposed above the front side of the conveying port, and the tapping plate is located below the guide cover. The edge of the tapping plate is provided with serrated tapping teeth.

[0016] In one optional embodiment, a power input shaft is provided on one side of the housing. The power input shaft is driven by a drive device and connected to the spiral feed roller. The power input shaft can realize the synchronous operation of the picking mechanism, the spiral conveying mechanism and the conveyor belt mechanism during operation. The power input shaft is connected to the transmission structure of the picking roller through a sprocket transmission consisting of a sprocket and a chain. The power input shaft is connected to the transmission structure of the conveyor belt through a belt transmission consisting of a belt, a pulley and a transmission rod.

[0017] In one alternative embodiment, the conveyor belt mechanism is located after the screw conveyor mechanism and is arranged at an upward angle to achieve the upward conveying of forage.

[0018] In one optional embodiment, a rotating roller is provided at the rear bottom of the housing, and the rotating roller is connected to the housing via an adjusting bracket.

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] 1. This application provides a feeding device for a hay picking and baling machine. A spiral conveying mechanism housed within the casing plays a crucial role in controlling the flow direction of the hay. The spiral feeding rollers are arranged laterally. During their rotation, they gradually push the hay brought in by the picking mechanism from both sides to the center, creating a spatial convergence trend from the outside in. Compared to existing technologies where hay enters the conveying path directly from the picking rollers without guidance or shaping, the spiral feeding structure significantly enhances the concentration of hay, reduces uneven lateral distribution, and provides initial assurance for the subsequent directional introduction and stable conveying of hay.

[0021] 2. In the application, after the forage is initially concentrated by the spiral feeding roller, a beating and guiding device located in its center further enhances the consistency of the forage's running direction. This device is located at a key node in the feeding path, loosening and guiding the forage before it enters the conveyor belt mechanism. Through this intervention, the forage achieves a clearer orientation in its longitudinal flow, helping to reduce channel blockage and tangling issues, thereby improving the overall smoothness of the feeding path and creating more stable feeding conditions for subsequent baling.

[0022] 3. This application, by setting up a spiral conveyor mechanism and a patting and guiding device, ensures that the hay, after being processed by these mechanisms, is smoothly discharged by the conveyor belt and fed into the main body of the baler for baling. Because the hay has already undergone lateral convergence and longitudinal posture adjustment before entering the conveyor belt, its arrangement in the conveying path is more orderly, and the overall feeding process is more coherent. Therefore, this embodiment, by sequentially configuring a pickup mechanism, a spiral conveyor mechanism, a patting and guiding device, and a conveyor belt mechanism in the feeding path, constructs a continuous feeding channel with centralized and directional capabilities, effectively improving the problem of directional disorder during hay transportation in actual operation.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0033] Please see Figures 1-6 This application provides a feeding device for a hay picking and baling machine, including a housing 100, a picking mechanism 200, a screw conveyor mechanism 300, a beating and guiding device 400, and a conveyor belt mechanism 500. Wherein:

[0034] The housing 100 includes left and right side plates and an upper cover, forming an internal feeding chamber;

[0035] The picking mechanism 200 is located in the lower front of the housing 100. The picking mechanism 200 includes a picking roller 210 with multiple spring teeth 211 evenly distributed on it. These teeth are used to pick up hay from the ground so that they can be elastically inserted into the hay and lifted up when in contact with the ground, thereby achieving efficient picking.

[0036] The screw conveyor mechanism 300 is located inside the housing 100 near the rear of the picking mechanism 200. The screw conveyor mechanism 300 includes a horizontally arranged screw feeding roller 310 that can gather the hay from both ends to the middle area. It is used to gather the hay and sort and push the hay during the rotation process.

[0037] The beating and guiding device 400 is located in the middle of the spiral feed roller 310 and is used to loosen and beat the forage during transportation and guide the forage backward.

[0038] The conveyor belt mechanism 500 is located at the rear of the housing 100. The conveyor belt mechanism 500 includes a rotatably mounted conveyor belt 510 for conveying the collected hay for subsequent baling operations.

[0039] In this embodiment, the spiral conveying mechanism 300, located inside the housing 100, plays a crucial role in controlling the flow direction of the forage conveying path. The spiral feeding roller 310 is arranged laterally; during its rotation, it gradually pushes the forage lifted by the picking mechanism 200 from both sides to the center, creating a spatial convergence trend from the outside in. Compared to the prior art where forage enters the conveying path directly from the picking roller without guidance and shaping, the spiral feeding structure significantly enhances the concentration of the forage, reduces the problem of uneven lateral distribution, and provides initial assurance for the subsequent directional introduction and stable conveying of forage.

[0040] After the hay is initially concentrated by the spiral feed roller 310, a beating and guiding device 400 located in its center further enhances the consistency of the hay's running direction. This device is situated at a critical node in the feeding path, loosening and guiding the hay before it enters the conveyor belt mechanism 500. Through this intervention, the hay achieves a clearer orientation in its longitudinal flow, helping to reduce channel blockages and hay tangling, thereby improving the overall smoothness of the feeding path and creating more stable feeding conditions for subsequent baling.

[0041] After being processed by the screw conveyor mechanism 300 and the beating and guiding device 400, the hay is smoothly discharged by the conveyor belt mechanism 500 and sent to the main body of the baler for baling. Because the hay has already undergone lateral convergence and longitudinal posture adjustment before entering the conveyor belt 510, its arrangement in the conveying path is more orderly, and the overall feeding process is more coherent. Therefore, this embodiment, by sequentially configuring the pickup mechanism 200, screw conveyor mechanism 300, beating and guiding device 400, and conveyor belt mechanism 500 in the feeding path, constructs a continuous feeding channel with centralized and directional capabilities, effectively improving the problem of directional disorder during hay transportation in actual operation.

[0042] In this embodiment, the picking mechanism 200 is positioned at the lower front of the housing 100, and a picking roller 210 structure with evenly distributed spring teeth 211 is adopted, enabling the device to continuously pick up forage from the ground during movement. The evenly distributed spring teeth 211 ensure strong continuity in the picking process, which is beneficial to improving picking efficiency. This structural arrangement also allows the forage to smoothly enter the feeding chamber inside the housing 100 from the front, providing space for subsequent centralized conveying. In addition, the picking roller 210 is installed close to the lower edge of the housing 100, which helps reduce the probability of forage being missed and improves the stability of the picking operation.

[0043] Furthermore, the spiral feeding roller 310, located behind the picking mechanism 200, adopts a transverse layout. During rotation, it pushes the hay located on the left and right sides towards the center via the feeding spiral blades 320, creating a feeding trend that converges "from both ends to the center." This structure allows the originally scattered hay to be consolidated before entering the next stage of operation, reducing conveying difficulties caused by hay shifting or localized accumulation. Simultaneously, because the spiral feeding roller 310 is arranged transversely parallel to the housing 100, the hay forms a natural transition in the horizontal direction, helping to reduce interference on the feeding path and making hay conveying more continuous and orderly.

[0044] Meanwhile, a beating and guiding device 400 is installed above the middle of the spiral feed roller 310 to further organize the forage after it has been gathered. The beating plate 420 can beat the forage entering the middle, making it loose and spread out, reducing the risk of the forage tangling and forming clumps. At the same time, it also guides the forage to move towards the area of ​​the conveyor belt 510. The beating and guiding device 400 is located in the key middle section of the feeding path, between the gathering and conveying, and acts as a transition bridge, providing good docking and transition conditions for the smooth operation of the conveyor belt mechanism 500, further enhancing the coordination and operational stability of the entire feeding process.

[0045] In some embodiments, such as Figure 4 As shown, the spring tooth 211 has a Y-shaped sheet structure. The spring tooth 211 is rotatably mounted on multiple tooth seats 212 on the outer circumference of the pickup roller 210. The multiple spring teeth 211 are arranged alternately on the pickup roller 210. The spring tooth 211 can swing as the pickup roller 210 rotates.

[0046] In this embodiment, the spring teeth 211 are further designed as Y-shaped sheet structures. Compared to traditional straight or hook-shaped spring teeth, this forked structure forms a certain angle in shape, providing a wider coverage area when in contact with forage. The angled structure between the two forks makes it easier forage to be caught between the teeth, thereby enhancing the adhesion of forage during pickup and improving pickup efficiency. At the same time, the Y-shaped sheet structure itself is relatively thin and has a certain degree of elasticity, allowing for slight deformation when in contact with the ground or grass layer. This compliant deformation ability helps to adapt to ground undulations or changes in grass density, improving the applicability and grassland adaptability of the pickup mechanism 200.

[0047] The spring teeth 211 are rotatably mounted on multiple tooth seats 212 on the outer circumference of the pickup roller 210, allowing each spring tooth to swing at a certain angle during the rotation of the pickup roller 210. This mounting method is more flexible than the traditional rigid fixing method, improving the dynamic adaptability of the spring teeth 211. When the spring teeth 211 encounter ground protrusions or hard obstacles during operation, they can swing to avoid them without damaging the structure, thereby reducing the impact on the spring tooth body, helping to reduce the structural wear rate, extend service life, and to some extent reduce the disturbance intensity to the turf or ground surface.

[0048] Multiple Y-shaped spring teeth 211 are arranged in a staggered structure on the pickup roller 210. The spring teeth at different angles and orientations are alternately set along the circumference, ensuring that in each rotation cycle of the pickup roller 210, spring teeth at different positions can sequentially contact the grass layer, achieving a continuous and distributed pickup effect. This staggered arrangement breaks the concentrated effect of grass entering the same circumference segment simultaneously, effectively reducing compaction during the pickup process and minimizing damage to the grass. Distributed pickup also improves contact uniformity, allowing the grass to enter the screw conveyor mechanism 300 in a more natural and loose state, providing more favorable grass flow conditions for subsequent grass aggregation and guidance, thereby further improving the stability and continuity of the feeding process. Optionally, the spring teeth 211 are made of high-elasticity alloy steel or wear-resistant spring steel to meet their elastic deformation requirements during frequent contact with the ground and grass. These materials have high fatigue resistance and can withstand long-term repeated bending without easily breaking. To improve their corrosion resistance, the surface can be further electroplated with zinc or powder coated. The combination of material strength and toughness helps extend the service life of the spring teeth in complex working environments and reduce maintenance frequency.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the axis of the spiral feed roller 310 is transversely parallel to the housing 100, and further as... Figure 6As shown, the outer surface of the spiral feed roller 310 is provided with feeding spiral blades 320 at both ends along the axial direction. The feeding spiral blades 320 at both ends are arranged in opposite directions to gather the forage at both ends to the middle area of ​​the spiral feed roller 310, and realize the sorting and propulsion of the forage to facilitate subsequent beating, guiding and conveying. This embodiment adopts a spiral feed roller 310 with this structure, so that the spiral feed roller 310 forms a three-section structure with feeding spiral blades 320 arranged on the left and right sides and no feeding spiral blades 320 arranged in the middle section.

[0050] In this embodiment, the axis of the spiral feeding roller 310 is arranged horizontally parallel to the housing 100, so that the spiral feeding roller 310 can cover the horizontal width of the feeding channel, which helps to receive hay from both left and right directions simultaneously. Moreover, during the hay conveying process, it can better avoid the problem of deviation or sudden change in transmission direction, so that the hay runs in a straight line, thereby improving the directional stability of hay conveying in terms of structure, and also creating a smoother path connection condition for the hay to smoothly enter the guiding device 400.

[0051] Feeding spiral blades 320 are respectively installed at both ends of the spiral feed roller 310, with the spiral blades rotating in opposite directions, forming a feeding trend of "left-right symmetry and convergence towards the center". The grass on the left is pushed towards the center under the action of the left-hand feeding spiral blade 320, and the grass on the right is similarly guided to the middle section by the right-hand feeding spiral blade 320, so that the grass is concentrated and organized in the central section of the feed roller 310. Compared with the traditional spiral feed roller with a single rotation direction, this symmetrical reverse design is more conducive to gathering the loose grass conveyed by the picking mechanism 200, reducing the lateral accumulation of grass in the feeding channel, and improving the concentration and neatness of the grass before entering the guide and conveyor belt mechanism 500.

[0052] During the feeding process, the feeding auger 320 not only concentrates the feeding of the forage but also provides a certain degree of pressure and shaping. Because the feeding auger 320 is in close contact with the outer surface of the auger roller 310, it applies a certain degree of gentle pressure to the forage as the roller rotates, causing some uneven or overlapping forage to be smoothly organized and guided into the central area. This gentle pressure reduces forage misalignment and avoids damage caused by excessive pressure, enhancing the straightness and consistency of the forage before it enters the beater plate 420 and conveyor belt 510, thus improving the neatness and continuity of the forage flow in the central feeding path.

[0053] In some embodiments, such as Figures 1-3As shown, a conveyor box 520 is provided on the outside of the conveyor belt 510. The conveyor box 520 is fixedly installed on the rear side of the housing 100. A conveying port 110 connected to the conveyor box 520 is provided on the rear side plate of the housing 100. The conveyor belt 510 is provided with protruding friction strips 511 to enhance the conveying capacity of forage.

[0054] Meanwhile, in this embodiment, the conveyor belt 510 is housed within a conveyor box 520, which is fixed to the rear side of the housing 100. This helps to provide a relatively enclosed and stable channel environment for the transport of forage. This structure effectively encloses the transport path spatially, reducing the probability of forage leakage, scattering, or wind interference during transport. Especially in complex work environments where the forage is loose and easily scattered, the conveyor box 520 can provide a degree of constraint and protection, improving the cleanliness of the feeding area and facilitating smooth integration with the baling mechanism.

[0055] Furthermore, a conveying port 110 is provided on the rear panel of the housing 100, connecting it to the conveying box 520, forming a clearly defined channel connection. This arrangement not only creates a clear inlet and outlet for the feeding path but also facilitates the smooth transition of hay from inside the housing 100 to the conveying box 520. The presence of the conveying port 110 structurally prevents hay from accumulating or getting stuck at the outlet, allowing hay to pass through naturally without obstruction from local edges. Simultaneously, the rear-mounted design of the conveying box 520 facilitates opening and maintenance, improving the convenience and practicality of overall machine maintenance.

[0056] Furthermore, the surface of the conveyor belt 510 is provided with multiple protruding friction strips 511. These protrusions form a traction structure with intervals, which can create a closer contact and engagement with the hay during the operation of the conveyor belt. Compared with traditional flat-surface conveyor belts, this design helps to reduce slippage, deviation, and stagnation of hay during the conveying process, and is particularly suitable for the clamping and transportation needs of loose or short hay. The presence of friction strips 511 improves the traction performance of the conveyor belt 510, which can significantly improve the conveying efficiency in actual operation, allowing the hay to be conveyed to the baling inlet position in a more stable state. In practical applications, the conveyor box 520 is also provided with a discharge port at the end away from the housing 100, for the smooth discharge of hay conveyed by the conveyor belt 510 to that end.

[0057] In some embodiments, such as Figure 2 and Figure 6As shown, the beating and guiding device 400 includes a guide cover 410 integrally formed with the housing 100 and a beating plate 420 fixedly disposed in the middle section of the spiral feed roller 310. The guide cover 410 is disposed above the front side of the conveying port 110, and the beating plate 420 is located below the guide cover 410. The edge of the beating plate 420 is provided with serrated beating teeth 421, which are used to directionally beat and loosen the forage before it enters the conveyor belt, thereby achieving smooth material guidance and anti-tangling functions.

[0058] In the above embodiments, the guide cover 410 and the housing 100 are integrally molded, which helps to reduce the number of components to be assembled and enhances the overall rigidity and durability of the structure. As a guiding component at the top of the feeding path, the guide cover 410 may frequently be subjected to the impact, vibration and friction of grass during operation. The integral structure can avoid loosening or deformation at the assembly joints, thereby better maintaining the stability of the guiding component in long-term operation. In addition, this integrated design also simplifies the manufacturing and assembly process, which not only helps to improve processing efficiency, but also reduces assembly interference problems caused by the superposition of component errors.

[0059] Meanwhile, in this embodiment, the patting plate 420 is located in the middle section of the spiral feeding roller 310, below the guide cover 410. This arrangement positions it at the forage concentration path. After the forage is gathered by the feeding spiral blades 320, it passes directly through the patting plate 420, where it is loosened and patted, helping to improve the problem of forage clumping or mixing. This structure does not hinder lateral concentration during the feeding process, and it also organizes and spreads the forage before it enters the conveyor inlet 110, creating favorable conditions for the stable clamping and conveying of the conveyor belt 510, and improving the smoothness of the feeding path and the continuity of operation.

[0060] The lower edge of the patting plate 420 is provided with serrated patting teeth 421. Compared with the traditional straight edge, this irregular edge structure can generate more contact points with the grass, forming a dispersing disturbance during the patting process. The multi-point patting action can effectively break up clumps of grass, reduce the risk of local accumulation of grass flow, and also facilitate the natural spread of grass and its smooth flow into the conveyor belt 510 area through the conveyor port 110. This structural design reduces the probability of grass entanglement and also guides the feeding channel smoothly, helping to improve the operational stability of the entire feeding process.

[0061] In some embodiments, such as Figure 2As shown, a power input shaft 600 is provided on one side of the housing 100. The power input shaft 600 is driven by a drive device and connected to the screw feed roller 310. The power input shaft 600 can realize the synchronous operation of the picking mechanism 200, the screw conveying mechanism 300 and the conveyor belt mechanism 500 during operation. The power input shaft 600 is connected to the transmission structure of the picking roller 210 through a sprocket transmission form composed of a sprocket and a chain. The power input shaft 600 is connected to the transmission structure of the conveyor belt 510 through a belt transmission form composed of a belt, a pulley and a transmission rod.

[0062] In the above embodiment, a power input shaft 600 is provided on one side of the housing 100, and the shaft is driven to rotate by a drive device 610. This is a design method that centralizes the power source. With this structure, the device only needs one main power unit to drive multiple key working components in the entire feeding system. This layout helps reduce the coordination difficulty between different drive components, reduces structural complexity, and also facilitates improved overall machine stability and subsequent maintenance efficiency. The location of the power input shaft 600 on one side of the housing 100 also facilitates connection to external power sources, results in clearer wiring, and provides relatively ample space for maintenance.

[0063] The power input shaft 600 is directly connected to the screw feed roller 310, and also establishes transmission links with the pickup roller 210 and the conveyor belt 510 through a sprocket drive structure and a belt drive structure, forming synchronous linkage among the three. Through this transmission method, the system can better maintain the speed coordination between key components during power output, reducing feeding problems caused by inconsistent speeds, such as grass accumulation or feeding interruptions. Relying on a single power shaft to achieve synchronous operation of the entire system helps maintain a consistent rhythm during grass pickup, collection, and conveying, improving feeding continuity.

[0064] Specifically, the pickup roller 210 and the power input shaft 600 are connected by a sprocket and chain, suitable for low-speed, high-torque working scenarios, which enhances the impact resistance and pickup force during the grass-picking process. The conveyor belt 510 and the power input shaft 600 are connected by a belt, pulleys, and drive rod, forming a transmission link that is more suitable for continuous and stable power transmission and facilitates control of the conveying rhythm. This approach of selecting different transmission forms according to the working needs of each part ensures that each working mechanism is in a more matched operating state, guaranteeing work efficiency while also helping to reduce system energy consumption and improve the overall machine's operational coordination and reliability.

[0065] It should be noted that the sprocket drive and belt drive methods used in this embodiment are common and mature power transmission structures in the field, characterized by simple structure, smooth transmission, and convenient maintenance, and can be directly applied to this type of mechanical equipment. Therefore, the specific structure and connection method of the above-mentioned chain drive and belt drive parts are conventional designs that can be selected and implemented by those skilled in the art according to actual needs, and will not be described in detail in this application.

[0066] In some embodiments, the conveyor belt mechanism 500 is located after the screw conveyor mechanism 300 and is arranged at an angle upward for conveying the forage upward.

[0067] Placing the conveyor belt mechanism 500 after the screw conveyor mechanism 300 is a structural layout that conforms to the natural transport process of forage. This "screw feeding at the front and rising conveyor at the rear" arrangement matches the direction of forage movement inside the housing 100, effectively avoiding unnecessary turns or backflows in the path. Through the sequential connection of the two mechanisms, the forage can directly transition into the area of ​​the conveyor belt 510 after being concentrated by the screw feeding roller 310, making the forage flow path simpler and helping to reduce the risk of accumulation and deviation during the transport process, thereby improving the continuity and smoothness of the feeding.

[0068] The conveyor belt mechanism 500 adopts an upward-sloping arrangement, enabling smooth transport of hay from a low to a high position. The inclined structure not only provides a path for hay lifting in the vertical direction but also allows for sufficient space for connection with the baling mechanism. Compared to a horizontal arrangement, the upward-sloping design allows for a more compact device structure and facilitates an upward-feeding mode for the baling mechanism, improving overall space utilization. The angled design also helps the hay to naturally compact under its own weight during transport, reducing interruptions in feeding caused by bouncing or slippage and improving transport stability.

[0069] This inclined conveyor structure also exhibits excellent installation adaptability, allowing for flexible docking with baling mechanisms of different heights or types. After being gathered and shaped by the beating and guiding device 400, the hay enters the baling area along the ascending path of the conveyor belt 510, demonstrating strong integration compatibility. Simultaneously, this spatially progressive conveyor structure also provides space for pre-processing before baling, facilitating the sorting, pre-compression, or orienting of the hay. This contributes to improving the overall modularity of the device and the convenience of subsequent maintenance, enhancing its applicability under various operating conditions.

[0070] In some embodiments, such as Figure 1 and Figure 5 As shown, a rotating roller 120 is provided at the rear bottom of the housing 100, and the rotating roller 120 is connected to the housing 100 through an adjusting bracket 130.

[0071] In the above embodiment, a rotating roller 120 is added at the rear bottom of the housing 100, providing structural support and sliding functionality. This rotating roller 120 is located at the rear end of the housing 100's bottom, forming a support structure together with the front ground wheel or traction wheel. This arrangement helps to distribute the load-bearing pressure on the ground, thereby reducing the burden on the rear structure. During forward operation or turning maneuvers, the rotating roller can roll smoothly along the ground, reducing resistance caused by sliding and thus lowering the direct friction between the bottom of the housing 100 and the ground. This makes the overall movement smoother and provides a certain degree of terrain adaptability.

[0072] The rotating drum 120 is connected to the housing 100 via an adjusting bracket 130, providing the drum with adjustable height or angle. Depending on the structure of the adjusting bracket, the gap between the drum and the ground can be flexibly adjusted according to different operating conditions. For example, when the terrain is uneven or the grass is dense, raising the drum height helps prevent grass accumulation and blockage; while in flat terrain with sparse grass, lowering the drum enhances the stability of the grounding support at the tail. Overall, this adjustable connection method improves the device's adaptability to various terrains and provides operators with more flexible adjustment options.

[0073] The roller 120 is installed at the tail of the feeding device, adjacent to the rear of the conveyor belt mechanism 500, thus playing a role in balancing the tail center of gravity in the overall structure. During hay baling operations, the feeding device may be subject to periodic impacts or vibrations from the hay. If the tail support is insufficient, local swaying or sinking may easily occur. This roller structure provides tail support, which can improve the device's anti-sway performance to a certain extent, making the device operate more smoothly. It also helps maintain the stability of the relative position between the conveying channel and the baling inlet, reducing the risk of hay shifting or getting stuck in the feeding path due to slight movements of the tail structure.

[0074] The feeding device of the hay picking and baling machine in this embodiment is typically connected to a tractor via a traction device before use, and the power input shaft 600 is linked to an external power unit. After the operation begins, the entire machine moves forward along the ground, and the picking mechanism 200 located at the lower front starts to operate. The picking roller 210 rotates under the drive of the power input shaft 600, and its outer circumference is equipped with staggered spring teeth 211. These spring teeth have a certain degree of elasticity and can insert into the hay and lift it up when they contact the ground. The picked hay is gradually lifted up as the picking roller 210 rotates and guided into the feeding chamber inside the housing 100, creating preliminary conditions for subsequent centralized transportation of hay.

[0075] The hay entering the feeding chamber then enters the screw conveyor mechanism 300. The screw feed roller 310 is horizontally positioned within the feeding chamber, with oppositely rotating feed screw blades 320 mounted at both ends. This structure guides the hay from both sides towards the center as the roller rotates, while simultaneously compressing it into a more compact state during the pushing process, forming a consistent flow of hay. The hay concentrated in the center of the feed roller 310 then passes through a beating and guiding device 400. A guide cover 410 covers the hay path, providing a guiding channel. Below the guide cover is a beating plate 420 with serrated edges 421, which agitates and guides the hay as it passes, improving its uniformity and reducing hay bundle overlap, facilitating a smooth transition of the hay to the subsequent conveying channel.

[0076] After being patted and guided, the hay continues along the path into the conveyor belt mechanism 500, which is located at the rear of the device. The surface of the conveyor belt 510 is provided with protruding friction strips 511, which enhance the clamping force of the hay on the belt surface and reduce feeding instability caused by slippage. The conveyor belt runs within a closed conveyor box 520, and the hay smoothly enters the baling area from the conveyor port 110. The conveyor belt 510 has an inclined upward structure, which can transport the hay to the baling mechanism entrance above the ground. A rotating roller 120 is located at the rear of the housing 100 and is connected to the housing via an adjusting bracket 130. This structure provides support for the rear and facilitates height adjustment in different terrains, making the entire machine run more smoothly during conveying, reducing the adverse effects of terrain interference, and facilitating efficient connection with subsequent baling processes.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
