Description

Technical Field

[0001] This utility model belongs to the field of baling machine technology, specifically, it relates to a separate feeding device for a double-outlet baling machine. Background Technology

[0002] In large-scale agricultural production, double-outlet balers, capable of simultaneously baling two streams of material, are nearly twice as efficient as traditional single-outlet balers, making them a core piece of equipment for processing stalk materials such as forage and straw. To achieve the core function of "dual-outlet baling," existing double-outlet balers primarily employ two feeding systems: "integrated feeding" and "separate feeding." However, both designs have significant drawbacks in practical applications, making it difficult to balance operational efficiency, material adaptability, and equipment stability.

[0003] All materials fed in the integrated system must pass through the same feeding channel and diversion node. If impurities (such as stones or metal fragments) are mixed in with the materials, or if high-moisture or highly entangled materials (such as silage straw) are being processed, the system is prone to jamming at narrow points in the channel or at the edges of the diversion plate. Since the process has no independent bypass, a single point of blockage will directly cause the entire feeding system to stop, requiring disassembly and cleaning of the channel, which seriously affects the continuity of field operations.

[0004] However, some existing double-outlet balers adopt a "completely independent separate feeding" design (such as two sets of independent picking mechanisms, two sets of independent augers and feeding channels), which is complex in structure, high in cost, and difficult to maintain.

[0005] There are also semi-independent separate feeding structures, such as a Chinese patent application number CN202510005614.7, which discloses an intermediate straw-splitting mechanism and system for a double-outlet baler, belonging to the field of baler technology. It includes an intermediate straw-splitting base plate, a power receiving and distributing structure, an active straw-pulling plate structure, and a driven straw-pulling plate structure. The power receiving and distributing structure transmits power to the active straw-pulling plate structure, which meshes with the driven straw-pulling plate structure. There is a rotational angle difference between the active straw-pulling plate of the active straw-pulling plate structure and the driven straw-pulling plate structure. The intermediate straw-splitting base plate is used to install the intermediate straw-splitting mechanism onto the double-outlet baler and serves as the supporting base plate for the power receiving and distributing structure, the active straw-pulling plate structure, and the driven straw-pulling plate structure. After receiving power, the power receiving and distributing structure first drives the active straw-pulling plate structure, and the driven straw-pulling plate structure moves synchronously. The straw-pulling plates of the active and driven straw-pulling structures are driven to swing back and forth, pushing the straw into the corresponding picking channels, thus achieving left and right material separation.

[0006] However, the grass-removing structure in this patent has weak adaptability and is prone to jamming and tangling. The grass-removing plate of the grass-separating mechanism has a fixed stroke design and cannot adjust the swing amplitude according to the fluctuation of the material quantity. When handling mixed materials of different lengths or wet materials, the grass-removing plate is easily tangled to form "material clumps", or jammed due to impurities entering the limiting gap, which increases the maintenance frequency and cost. Utility Model Content

[0007] The main technical problem to be solved by this utility model is to provide a separate feeding device for a double-outlet baler with a simple overall structure that can feed hay separately and evenly during the use of a double-outlet baler, avoid hay clogging, extend the service life of the equipment, and improve the performance.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A separate feeding device for a double-outlet baler includes a first feeding bracket and a second feeding bracket, which are fixedly connected by an intermediate feeding bracket. The first feeding bracket and the second feeding bracket are symmetrically arranged. The first feeding bracket and the intermediate feeding bracket are designated as a first feeding position, and the second feeding bracket and the intermediate feeding bracket are designated as a second feeding position. A first inclined plate and a second inclined plate are fixedly installed on the intermediate feeding bracket at positions corresponding to the first feeding position and the second feeding position, and the first inclined plate and the second inclined plate are symmetrically arranged.

[0010] The following are further optimizations of the above technical solution by this utility model:

[0011] A first feeding component is also provided between the first feeding bracket and the intermediate feeding bracket, and a first arc-shaped support plate is fixedly installed in the first feeding position below the first feeding component.

[0012] Further optimization: A second feeding component is also provided between the second feeding bracket and the intermediate feeding bracket, and a second arc-shaped support plate is fixedly installed in the second feeding position below the second feeding component.

[0013] Further optimization: The side of the first feeding bracket away from the middle feeding bracket is set as the first conveying position, and the first conveying position is connected to the first feeding position.

[0014] Further optimization: The side of the second feeding bracket away from the middle feeding bracket is set as the second conveying position, and the second conveying position is connected to the second feeding position.

[0015] Further optimization: Pick-up devices are also provided at one side of the first feeding bracket, the intermediate feeding bracket, and the second feeding bracket.

[0016] Further optimization: The pickup device is divided into three areas: left pickup position, middle pickup position, and right pickup position.

[0017] Further optimization: A connecting arc plate is fixedly installed on the intermediate feeding bracket at the position corresponding to the first feeding position and the second feeding position. The side of the first inclined plate near the intermediate feeding bracket and the side of the second inclined plate near the intermediate feeding bracket are respectively fixedly installed on both sides of the connecting arc plate.

[0018] Further optimization: The side of the first inclined plate away from the middle feeding bracket is fixedly connected to the side of the second inclined plate away from the middle feeding bracket.

[0019] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. By dividing the picking device into three independent picking positions, left, middle and right, the material enters the subsequent stage through "first conveying position + first feeding position", "sloping plate diversion + double feeding position" and "second conveying position + second feeding position" respectively. If one channel is temporarily blocked due to impurities (such as gravel) or high moisture material, it only affects the operation of that single channel, while the other channel can operate normally, avoiding the situation of "the whole machine stopping for cleaning". In conjunction with the round hole screening function of the first and second arc-shaped pallets, gravel and soil mixed in the material are discharged through the round holes in advance, reducing the probability of impurities entering the feeding component and further reducing the risk of blockage.

[0020] The symmetrical ramps formed by the first and second inclined plates can achieve natural diversion of intermediate materials by gravity alone without the need for electric / hydraulic drive. Furthermore, the ramp angle is adapted to the flowability of materials with different specific gravities, such as hay and straw. When processing mixed materials of different lengths, the situation of "straw boards getting tangled in material clumps" will not occur.

[0021] At the same time, the structure is simplified to reduce costs. The core diversion components (first inclined plate and second inclined plate) are fixed metal structures with no wear of moving parts. The feed blades adopt a standardized design, and only a single set of blades needs to be replaced during maintenance, without disassembling the entire channel.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0027] like Figure 1-3 As shown: A separate feeding device for a double-outlet baler includes a first feeding bracket 1 and a second feeding bracket 2. The first feeding bracket 1 and the second feeding bracket 2 are fixedly connected by an intermediate feeding bracket 3. The first feeding bracket 1 and the second feeding bracket 2 are symmetrically arranged. The first feeding position 11 is set between the first feeding bracket 1 and the intermediate feeding bracket 3, and the second feeding position 21 is set between the second feeding bracket 2 and the intermediate feeding bracket 3. A first inclined plate 33 and a second inclined plate 34 are fixedly installed on the intermediate feeding bracket 3 at positions corresponding to the first feeding position 11 and the second feeding position 21. The first inclined plate 33 and the second inclined plate 34 are symmetrically arranged.

[0028] A first feeding component 12 is also provided between the first feeding bracket 1 and the intermediate feeding bracket 3.

[0029] A first arc-shaped support plate 13 is fixedly installed in the first feeding position 11 at a position below the first feeding component 12.

[0030] A second feeding component 22 is also provided between the second feeding bracket 2 and the intermediate feeding bracket 3.

[0031] A second arc-shaped support plate 23 is fixedly installed in the second feeding position 21 at a position below the second feeding component 22.

[0032] The first arc-shaped pallet 13 and the second arc-shaped pallet 23 are evenly provided with a plurality of round holes. These round holes can screen the picked-up materials (such as pasture and straw) on the first arc-shaped pallet 13 and the second arc-shaped pallet 23, so that the impurities such as gravel and soil mixed in the materials fall naturally through the round holes, thereby achieving the separation of impurities from effective materials and preventing gravel from entering the subsequent processing stage with the materials.

[0033] The side of the first feeding bracket 1 away from the middle feeding bracket 3 is set as the first conveying position 4. The first conveying position 4 is connected to the first feeding position 11. With this design, the forage, straw and other materials in the first conveying position 4 can enter the first feeding position 11.

[0034] The side of the second feeding bracket 2 away from the middle feeding bracket 3 is set as the second conveying position 5, and the second conveying position 5 is connected to the second feeding position 21.

[0035] The first conveying position 4 is equipped with a first auger conveyor, and the second conveying position 5 is equipped with a second auger conveyor, which is not shown in the figure.

[0036] The first auger conveyor and the second auger conveyor are existing auger conveying equipment, which can convey materials such as hay and straw to the first feeding position 11 and the second feeding position 21 respectively.

[0037] Pick-up devices 6 are also provided on one side of the first feeding bracket 1, the middle feeding bracket 3, and the second feeding bracket 2.

[0038] The picking device 6 is a component used in existing balers to collect, transport, and pre-compress loose forage, straw, and other materials scattered on the field surface. It is a relatively mature component, and its specific structure and picking principle will not be described in detail here.

[0039] The pickup device 6 is divided into three areas: left pickup position 61, middle pickup position 62, and right pickup position 63.

[0040] The left pick-up position 61 corresponds to the first transport position 4 and the first feed position 11.

[0041] The intermediate pickup position 62 corresponds to the positions of the first inclined plate 33 and the second inclined plate 34 on the intermediate feeding bracket 3.

[0042] The right pick-up position 63 corresponds to the second transport position 5 and the second feed position 21.

[0043] With this design, the forage, straw and other materials picked up by the picking device 6 at the left picking position 61 are sent to the first conveying position 4 and the first feeding position 11. The materials in the first conveying position 4 are then conveyed to the first feeding position 11 by the first auger conveyor.

[0044] The forage, straw and other materials picked up by the picking device 6 at the right picking position 63 are sent to the second conveying position 5 and the second feeding position 21. The materials in the second conveying position 5 are then conveyed to the second feeding position 21 by the second auger conveyor.

[0045] A connecting arc plate 32 is fixedly installed on the intermediate feeding bracket 3 at the position corresponding to the first feeding position 11 and the second feeding position 21.

[0046] The first inclined plate 33 is fixedly installed on the side of the middle feeding bracket 3 and the second inclined plate 34 is fixedly installed on the two sides of the connecting arc plate 32.

[0047] The side of the first inclined plate 33 away from the middle feeding bracket 3 is fixedly connected to the side of the second inclined plate 34 away from the middle feeding bracket 3.

[0048] With this design, the first inclined plate 33 and the second inclined plate 34 form two slopes at a certain angle. The two slopes extend towards the first feeding position 11 and the second feeding position 21, respectively. When the forage, straw and other materials collected at the middle picking position 62 of the picking device 6 are sent to the first inclined plate 33 and the second inclined plate 34, they will slide to the first feeding position 11 and the second feeding position 21 under the action of the two slopes, achieving efficient distribution of separate feeding and reducing the risk of blockage in subsequent processes.

[0049] Meanwhile, as the material slides down the slope, it will naturally be laid out in layers (rather than stacked vertically), and the length direction of the material will be more in line with the extension direction of the slope (i.e., consistent with the feeding direction of the feeding position). This is equivalent to completing the material sorting in advance. After this oriented, layered material enters the feeding position, it can be more smoothly bitten and conveyed by the feeding roller, greatly reducing feeding jams caused by horizontal placement and stacking of materials, and reducing the equipment failure rate.

[0050] The first feeding assembly 12 includes two first drive shafts 121 located on opposite sides of the first feeding bracket 1 and the intermediate feeding bracket 3, respectively.

[0051] Each of the two first drive shafts 121 is fitted with a first lifting lug 122, and the same first rotating shaft 123 is fixedly installed between the two first lifting lugs 122.

[0052] Multiple first feeding blades 124 are evenly spaced on the first rotating shaft 123.

[0053] With this design, the forage, straw and other materials entering the first feeding position 11 are fed backward by the rotating first feeding blade 124 and transported to the subsequent process.

[0054] The specific structure and rotation method of the multiple first feeding blades 124 to achieve the principle of feeding loose forage, straw and other materials are relatively mature structural components in the existing technology, and will not be described in detail here.

[0055] The other ends of the two first drive shafts 121 are connected to the power system in the baler to realize the rotation of the first drive shafts 121.

[0056] The second feeding assembly 22 includes two second drive shafts 221 located on the opposite side of the second feeding bracket 2 and the intermediate feeding bracket 3, respectively.

[0057] Each of the two second drive shafts 221 is fitted with a second lifting lug 222, and the same second rotating shaft 223 is fixedly installed between the two second lifting lugs 222.

[0058] Multiple second feeding blades 224 are evenly spaced on the second rotating shaft 223.

[0059] With this design, the forage, straw and other materials entering the second feeding position 21 are fed backward by the rotating second feeding blade 224 and transported to the subsequent process.

[0060] The specific structure and rotation method of the multiple second feeding blades 224 to feed loose forage, straw and other materials are relatively mature structural components in the existing technology, and will not be described in detail here.

[0061] When the double-outlet baler is in operation, the picking device 6 (an existing mature loose material collection component) is activated and comes into contact with loose pasture, straw and other materials on the ground. The left picking position 61 collects the material on the left side of the machine body and conveys it to the first conveying position 4 and the first feeding position 11. The right picking position 63 collects the material on the right side of the machine body and conveys it to the second conveying position 5 and the second feeding position 21. The middle picking position 62 collects the material below the machine body and conveys it to the junction of the first inclined plate 33 and the second inclined plate 34.

[0062] The first auger conveyor then transports the material from the first conveying position 4 to the first feeding position 11, and the second auger conveyor then transports the material from the second conveying position 5 to the second feeding position 21. When the concentrated material from the intermediate pickup position 62 reaches the first inclined plate 33 and the second inclined plate 34, it is automatically divided into two paths under the gravity guidance of the slopes on both sides: one path slides into the first feeding position 11 along the slope of the first inclined plate 33, and the other path slides into the second feeding position 21 along the slope of the second inclined plate 34, thus completing the intermediate material diversion and finally realizing the conversion from three-way collection to two-way feeding.

[0063] During this process, the materials at the first feeding position 11 and the second feeding position 21 fall onto the first arc-shaped pallet 13 and the second arc-shaped pallet 23 below, respectively. Impurities such as gravel and soil mixed in the materials (with a density greater than the materials) fall naturally into the field through the round holes under their own weight and slight vibrations during the material conveying process. The effective materials (forage and straw) are supported by the pallets and remain in the feeding position because their length and volume are greater than the diameter of the round holes, thus preventing impurities from entering the subsequent stages with the materials and protecting the core components of the equipment.

[0064] The core function of the first inclined plate 33 and the second inclined plate 34 is to achieve uniform distribution of intermediate materials and ensure synchronous operation of dual feeders. The materials collected at the intermediate pick-up position 62 are in a concentrated accumulation state. If they are directly conveyed, it is easy to cause overload of one feeder position and material shortage at the other feeder position. The first inclined plate 33 and the second inclined plate 34 are designed to achieve distribution. The two inclined plates are symmetrically fixed on both sides of the connecting arc plate 32, forming two slopes with a certain angle. The slopes extend towards the first feeder position 11 and the second feeder position 21 respectively, providing a dedicated guiding channel for intermediate materials. After the concentrated materials reach the inclined plates, no additional power is required. They can be naturally distributed along the slope by gravity alone, ensuring that the material feed of the two paths is balanced and avoiding feeding jams or equipment idling caused by uneven material distribution. This fully leverages the efficiency advantage of parallel operation of the dual-output baler (nearly double the efficiency of single-output baler).

[0065] Materials such as hay and straw vary in length and are prone to tangling. If they enter the feeding position in an disorderly manner, the feeding blades are easily jammed due to horizontal stacking. The inclined plate guides the material through the slope and optimizes the material posture during the diversion process. After the material enters the feeding position in a forward and layered manner, it can be more smoothly conveyed by the first feeding blade 124 and the second feeding blade 224, which greatly reduces the jamming caused by horizontal stacking and tangling of materials, reduces the equipment failure rate, and reduces downtime for maintenance (avoiding the defect of the existing integrated feeding solution where a single point blockage causes the whole machine to stop).

[0066] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
