Description

Technical Field

[0001] This utility model belongs to the field of baling machine technology, specifically, it relates to a forced feeding device for a round bale baling machine. Background Technology

[0002] In existing technologies, crop straw resources are abundant. As a clean and renewable resource, it has broad application prospects in many fields such as biomass power generation, soil fertilizer, and animal feed. However, straw itself has low density, is scattered in shape, and occupies a lot of space, which brings great inconvenience to transportation and storage. This problem seriously restricts the industrial utilization of straw. Baling straw into bales before further processing has become a key link in reducing the cost of raw material collection and storage and promoting the efficient utilization of straw resources. Therefore, straw picking, compressing, and baling machinery has been increasingly widely used in modern agricultural production.

[0003] The forced feeding system is a core component of round bale balers, responsible for the crucial task of smoothly and efficiently transferring the straw or hay collected by the pickup to the compression system. Its performance directly determines the overall operating efficiency and stability of the baler. However, existing round bale baler feeding devices still have many problems that urgently need to be solved in practical applications, making it difficult to meet the demands of modern agriculture for efficient and stable operation.

[0004] Especially after the feed is pushed by the rotor, the baffle plate is fixed above and behind the rotor, forming a one-way channel. When the material is forcibly pushed to the rear by the rotor, the baffle plate prevents the material from flowing back to the feed inlet, avoiding the accumulation and blockage of the backflowing material and the newly entered material. Therefore, the role of the baffle plate is crucial. However, in the existing design, the baffle plate and the rotor mounting plate are designed as an integral fixed design. When large pieces of material or impurities are pushed by the rotor and collide with the baffle plate, they are prone to bending and breakage. In particular, the connection between the baffle plate and the rotor mounting plate is prone to breakage, resulting in a high maintenance frequency. In addition, the specified gap of the baffle plate is fixed and cannot be adjusted. When the gap is too large, some material is prone to escape and flow back from the gap; when the gap is too small, the rotating blades are prone to friction with the edge of the baffle plate when rotating, accelerating the wear of both, making replacement difficult and wasting manpower.

[0005] Chinese patent application CN2016210712562 discloses an integral rotor for a baler feeding system. The rotor includes a rotating shaft, rotating stacks for pushing material from front to back, and pushers for conveying material from both sides to the rotating stacks. The pushers include a left-hand pusher and a right-hand pusher, located at the left and right ends of the rotating shaft, respectively. Several rotating stacks are fixedly mounted on the rotating shaft between the left-hand and right-hand pushers. The rotating stacks and pushers rotate synchronously with the rotating shaft. A power input shaft and a fixed shaft are respectively located at both ends of the rotating shaft. This utility model provides an integral rotor for a baler feeding system. This device can replace the multi-shaft structure of the rotating part of the traditional feeding system, achieving a large feeding capacity, simplifying the structure, reducing the load on the feeding system, and improving the working efficiency of the baler. In this patent, the baffle plate and rotor assembly are designed as a single unit, which means the installation angle cannot be adjusted, increasing maintenance costs. Utility Model Content

[0006] The main technical problem to be solved by this utility model is to provide a forced feeding device for a round bale baler with a simple overall structure that can ensure the feeding effect of the baffle plate during the operation of the forced feeding device, avoid material leakage and blockage by adjusting the installation angle of the baffle plate, and facilitate maintenance and replacement of the baffle plate, thereby improving the performance of the device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A forced feeding device for a round bale baler includes a spiral auger device, a rotor feeding assembly rotatably mounted inside the spiral auger device, a baffle plate adjustablely mounted above the output end of the rotor feeding assembly on the spiral auger device, a pickup assembly rotatably mounted at the input end of the rotor feeding assembly on the spiral auger device, a straw pressing roller assembly hinged to the spiral auger device above the pickup assembly, and a straw pressing rake assembly fixedly mounted on the straw pressing roller assembly.

[0008] The following are further optimizations of the above technical solution by this utility model: The spiral auger device includes two first mounting plates fixedly installed on both sides of the round bale baler support. Two second mounting plates are also arranged symmetrically at intervals between the two first mounting plates. A U-shaped plate is fixedly installed between the second mounting plate and the adjacent first mounting plate. The U-shaped groove on the U-shaped plate is set as a spiral auger groove. The rotor feeding assembly is rotatably mounted on two first mounting plates via bearings.

[0009] Further optimization: Multiple spaced second mounting holes are provided on the second mounting plate near the bottom of the spiral auger groove.

[0010] Further optimization: The baffle plate includes two symmetrically spaced connecting plates, which can be adjusted and installed on corresponding second mounting plates.

[0011] Further optimization: Multiple first mounting holes are provided on the connecting plate at positions corresponding to the second mounting holes.

[0012] Further optimization: The multiple first mounting holes and multiple second mounting holes are arranged in a U-shape, and the multiple first mounting holes and multiple second mounting holes can freely correspond to each other.

[0013] Further optimization: The two connecting plates are fixedly connected to the same flat plate, and the two connecting plates are also fixedly connected to the same vertical plate, which is also vertically arranged on one side of the flat plate.

[0014] Further optimization: Multiple partition plates are vertically arranged on the flat plate, and one side of each partition plate is fixedly connected to the vertical plate. A clearance groove is provided between each pair of adjacent partition plates on the flat plate.

[0015] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It can optimize the feeding stability and reduce the occurrence of failures. The angle of the baffle plate can be freely adjusted through the first and second mounting holes arranged in a U shape, which can adapt to different material thicknesses and sizes. At the same time, it avoids the problem of material leakage and backflow caused by excessive gaps or component friction caused by excessive gaps. Meanwhile, the clearance groove on the plate is precisely matched with the rotor blades. With the diversion effect of the partition plate, it effectively prevents material overflow and accumulation blockage, and ensures continuous and smooth feeding.

[0016] At the same time, it reduces maintenance costs and improves ease of use. The baffle plate adopts a detachable installation design instead of being fixed as a whole. When it is bent or broken due to the impact of large materials, there is no need to replace the whole part. The maintenance and disassembly are simple. The baffle plate has a simple structural design and the replacement process after wear is convenient, reducing manpower input and downtime, and reducing long-term use costs.

[0017] In addition, the overall structure is simple, reliable, and highly adaptable. The overall structure consists of core components such as a spiral auger device, a pickup assembly, and a rotor feeding assembly. It is compact in design, easy to install, and can be adapted to most existing round bale baling machine brackets.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] like Figure 1-5 As shown: A forced feeding device for a round bale baler includes a spiral auger device 1, a rotor feeding assembly 3 rotatably installed inside the spiral auger device 1, a baffle plate 4 adjustablely installed above the output end of the rotor feeding assembly 3 on the spiral auger device 1, a picking assembly 2 rotatably installed on the spiral auger device 1 at the input end of the rotor feeding assembly 3, a straw pressing roller assembly 5 hinged to the spiral auger device 1 above the picking assembly 2, and a straw pressing rake assembly 6 fixedly installed on the straw pressing roller assembly 5.

[0022] like Figure 2 , Figure 4 As shown in the figure, the spiral auger device 1 includes two first mounting plates 11 fixedly installed on both sides of the round bag baler support, and the two first mounting plates 11 are arranged symmetrically.

[0023] Two second mounting plates 12 are also provided between the two first mounting plates 11, arranged symmetrically at intervals.

[0024] A U-shaped plate 13 is fixedly installed between the second mounting plate 12 and the adjacent first mounting plate 11, and the U-shaped groove on the U-shaped plate 13 is configured as a spiral auger groove.

[0025] The rotor feeding assembly 3 is rotatably mounted on two first mounting plates 11 via bearings.

[0026] The rotational installation method of the rotor feeding assembly 3 is well known in the prior art and will not be described in detail here.

[0027] The second mounting plate 12 has multiple spaced second mounting holes 121 near the bottom of the spiral auger groove.

[0028] like Figure 3As shown, the rotor feeding assembly 3 includes a rotating shaft 31 that is rotatably mounted on two first mounting plates 11 via bearings.

[0029] The first spiral auger 32 and the second spiral auger 33 are respectively spirally installed on the outer surfaces of both ends of the rotating shaft 31 at positions corresponding to the spiral auger grooves, that is, the first spiral auger 32 and the second spiral auger 33 are respectively located in the two spiral auger grooves.

[0030] The first spiral auger 32 and the second spiral auger 33 have opposite spiral directions. This design ensures that when the rotating shaft 31 drives the first spiral auger 32 and the second spiral auger 33 to rotate, the first spiral auger 32 and the second spiral auger 33 will uniformly transport the feed to the center of the rotating shaft 31.

[0031] Multiple blades 34 are fixedly installed on the outer surface of the rotating shaft 31 between the first spiral auger 32 and the second spiral auger 33.

[0032] Multiple blades 34 are arranged in a spiral interval. The structure and installation method of the blades 34 are known in the prior art and will not be described in detail here.

[0033] Multiple blades 34 can ensure stable material conveying and regular flow, and can ensure uniform conveying for a certain type of material.

[0034] like Figure 5 As shown, the baffle plate 4 includes two symmetrically spaced connecting plates 41, which can be adjusted and installed on corresponding second mounting plates 12.

[0035] The connecting plate 41 has a plurality of first mounting holes 42 at positions corresponding to the second mounting holes 121.

[0036] In this embodiment, the multiple first mounting holes 42 and the multiple second mounting holes 121 are arranged in a U-shape, and the multiple first mounting holes 42 and the multiple second mounting holes 121 are freely corresponding to each other. With this design, the installation angle of the baffle plate 4 can be freely adjusted, thereby improving the performance.

[0037] A flat plate 44 is fixedly connected between two connecting plates 41, and a vertical plate 43 is also fixedly connected between the two connecting plates 41. The vertical plate 43 is simultaneously arranged vertically on one side of the flat plate 44.

[0038] Multiple partition plates 45 are vertically arranged on the flat plate 44, and one side of each partition plate 45 is fixedly connected to the vertical plate 43.

[0039] The plate 44 has clearance grooves 441 between two adjacent partition plates 45. The width of the clearance grooves 441 matches the thickness of the blades 34, and the number of clearance grooves 441 matches the number of blades 34.

[0040] The position of the blade 34 matches the position of the clearance groove 441.

[0041] With this design, when the rotor feeding assembly 3 rotates to convey feed, the rotating shaft 31 rotates clockwise. During this time, the feed collected by the blades 34 is blocked by the plate 44, and the feed falls off the blades 34. With the cooperation of the clearance groove 441, the feed is prevented from overflowing.

[0042] By adjusting the corresponding positions of the first mounting hole 42 and the second mounting hole 121 on the connecting plate 41, the angle of the baffle plate 4 can be adjusted, thereby improving the performance of the baffle plate 4 and facilitating its replacement when it is severely worn.

[0043] The pressing roller assembly 5 and the pressing rake assembly 6 can initially compact and guide the straw, reduce gaps, and increase the density of the straw, laying the foundation for subsequent winding. Their specific structure is known in the prior art and will not be described in detail here.

[0044] In this embodiment, the rotational power of the pickup component 2 and the rotor feeding component 3 is provided through gears and chains and the power system of the baler. The specific structure is known in the prior art and will not be described in detail here.

[0045] 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.
