Description

Technical Field

[0001] The present invention relates to a forage harvesting machine, in particular to a pick-up and feeding assembly for a baler. On this basis, the present invention also relates to a baler comprising the pick-up and feeding assembly. Background Art

[0002] A baler is an agricultural machine used to collect and bundle straw and forage, such as rice straw, wheat straw, cotton stalks, corn stalks, rapeseed stalks, peanut vines, and bean stalks. Typically, a baler consists of a picker, a feeder, and a baling chamber (forming chamber). As the baler is driven or towed forward, the picker picks up forage, such as grass, from the ground and feeds it into the forming chamber via the feeder. After the bales are formed, the forage can be easily transported and stored.

[0003] Due to factors such as the type of forage and its moisture and impurity content, forage picked up by the picker's spring-loaded tines often cannot be fully conveyed to the feeder, but instead accumulates in the dead zone between the picker and the feeder, damaging the picker and affecting the overall performance of the machine. To address this, Chinese invention patent application CN112997696A provides a guided picker anti-blocking structure. This structure prevents forage from entering the gap in the bearing area by installing baffle shields at both ends of the tine. Furthermore, a grass guide plate connected to the outer wall of the baffle shield guides the forage into the working area of ​​the auger blades, reducing forage accumulation in the dead zone on both sides of the picker.

[0004] However, the above-mentioned prior art cannot prevent the abnormal accumulation of grass in the dead corner area of ​​the conveying between the picking device and the feeding device. During operation, grass can easily enter the gap between the picking device and the feeding device, causing grass blockage and damaging working parts such as the spring teeth. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that grass and grass are easily accumulated in the conveying dead angle area and gap between the picking device and the feeding device during the operation of the baler, and to provide a picking and feeding assembly for the baler. The picking and feeding assembly can effectively eliminate the conveying dead angle area and gap between the picking device and the feeding device, so that the grass and grass picked up by the picking device can be smoothly conveyed to the feeding device, avoiding damage to working parts such as the spring teeth due to accumulation and blockage.

[0006] In order to achieve the above objectives, the present invention provides a pick-up and feeding assembly for a baler, comprising:

[0007] A picking device comprising a plurality of picking rack grass separating plates arranged at intervals from each other and a spring tooth that can be driven to rotate about a main axis and move through the gaps between the picking rack grass separating plates to pick up grass and transport it to the upper side of the picking rack grass separating plates;

[0008] a feeding device having a feeding bottom plate for receiving the grass material picked up by the picking device; and

[0009] An anti-grass blocking device includes an elastic base plate having a mounting portion connected to the feeding base plate and a plurality of deformation portions extending from the mounting portion toward the picking device and arranged at intervals from each other, each of the deformation portions being respectively connected to a corresponding picking rack grass dividing plate so that when the grass is transported from the picking rack grass dividing plate to the feeding base plate, the deformation portion undergoes elastic deformation to allow the picking device and the feeding device to move relative to each other.

[0010] Preferably, the mounting portion is formed with a countersunk hole and is connected to the feed base plate by a countersunk screw passing through the countersunk hole and screwed to the feed base plate.

[0011] Preferably, the deformation portion is formed with a waist-shaped hole extending from the mounting portion toward the picking device, and is connected to the corresponding grass dividing plate of the picking frame by a first bolt passing through the waist-shaped hole.

[0012] Preferably, the grass blocking prevention device further comprises a material guiding mechanism installed on the deformation portion, and the material guiding mechanism has an arc-shaped top surface for guiding the grass to be transported from the grass dividing plate of the picking rack to the feeding bottom plate.

[0013] Preferably, the material guiding mechanism includes a contour plate mounted on the deformation portion, the contour plate forming an upwardly arched contour plate top surface which serves as at least a part of the arc-shaped top surface, and is spaced apart from the top surface of the deformation portion at both ends facing the grass separating plate of the picking rack and the feeding bottom plate.

[0014] Preferably, the profiling plate is formed into an H-shaped structure and comprises a connecting portion connected to the deformation portion via a second bolt and profiling portions respectively connected to both ends of the connecting portion, and the top surface of the profiling plate is formed on the profiling portion.

[0015] Preferably, the material guiding mechanism also includes a front buffer and a rear buffer respectively connected to the two ends of the profiling plate facing the picking rack grass dividing plate and the feeding bottom plate and respectively resting on the top surface of the deformation part, and the front buffer and the rear buffer are respectively rubber parts.

[0016] Preferably, the front buffer and the rear buffer are formed with a front buffer top surface and a rear buffer top surface which are part of the arc-shaped top surface and are flush with and adjacent to the top surface of the contour plate.

[0017] Preferably, the front bumper top surface extends from a position adjacent to the top surface of the contoured plate to a position adjacent to the top surface of the deformation portion, and / or the rear bumper has a partition located in the gap between the contoured plate and the top surface of the deformation portion.

[0018] A second aspect of the present invention provides a baler comprising the above-mentioned pick-up and feeding assembly.

[0019] Through the above technical solution, the pick-up and feeding assembly of the present invention can pick up grass on the ground using spring teeth driven to rotate about a main axis, and then cause the grass to fall off the spring teeth as the spring teeth move through the gaps between the grass dividing plates of the pick-up frame. The grass that falls off the spring teeth is then transported to the feeding device through an anti-blocking device. Since the anti-blocking device is respectively connected to the pick-up device and the feeding device, it can effectively eliminate the gap between the pick-up device and the feeding device, allowing the grass to be transported smoothly to the feeding device. Furthermore, since the elastic base plate of the anti-blocking device has an elastically deformable deformation portion, the deformation portion can elastically deform during operation to adapt to changes in the relative position between the pick-up device and the feeding device (i.e., to adapt to the floating of the pick-up device relative to the feeding device and the entire machine), thereby reducing or eliminating the conveying dead angle area between the pick-up device and the feeding device, facilitating the conveying of grass picked up by the pick-up device to the feeding device, avoiding damage to working components such as the spring teeth due to accumulation and blockage, and improving the stability and reliability of the entire machine.

DETAILED DESCRIPTION

[0030] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0031] In the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to up, down, left, right as shown in the reference drawings; "inside, outside" refer to inside and outside relative to the outline of each component itself.

[0032] Reference Figures 1 to 3As shown, a pick-up and feeding assembly for a baler according to a preferred embodiment of the present invention includes a pick-up device 1, a feeding device 2, and a grass blocking prevention device 3 connected between the pick-up device 1 and the feeding device 2. The pick-up device 1 is used to pick up grass and other forage from the ground. It includes a plurality of pick-up frame grass separating plates 11 arranged at intervals from each other and spring teeth 12 that can be driven to rotate about a main axis and move through the gaps between the pick-up frame grass separating plates 11. Generally, the spring teeth 12 can be slender rod-shaped components made of steel wire or other materials with a certain degree of elasticity. Multiple spring teeth 12 are evenly mounted on the outer circumference of a roller. When the main axis of the pick-up device 1 rotates, the spring teeth are driven to rotate along the circumference to pick up forage from the ground. As the forage passes through the pick-up frame grass separating plates 11, the spring teeth 12 are caused to fall off the spring teeth 12 and are then picked up and transported to the pick-up frame grass separating plates 11. The feeding device 2 has a feeding base 21 for receiving the grass picked up by the pickup device 1 and is capable of transporting the grass to the forming chamber for baling and forming in the forming chamber to facilitate subsequent transportation and storage. It is understandable that since the pickup and feeding assembly of the present invention mainly solves the problem of grass accumulation and blockage by connecting the grass blocking device 3 between the pickup device 1 and the feeding device 2, only the main relevant parts of the pickup device 1 and the feeding device 2 are described and shown in the above description and figures. The pickup device 1 and the feeding device 2 can have the same other components (such as the driving mechanism of the pickup device, the feeding mechanism of the feeding device, etc.) and working principles as the corresponding working devices of the baler in the prior art, and therefore further details will not be described.

[0033] In the picking and feeding assembly of the present invention, the grass blocking prevention device 3 includes an elastic bottom plate 31 respectively connected to the picking device 1 and the feeding device 2, so as to facilitate the grass picked up by the picking device 1 to be transported to the feeding device 2. Specifically, Figure 2 and Figure 3 As shown, the elastic base plate 31 has a mounting portion 311 and multiple deformable portions 312 extending from the mounting portion 311 toward the pickup device 1. The mounting portion 311 is connected to the feeding base plate 21 of the feeding device 2. The multiple deformable portions 312 are spaced apart and connected to corresponding picking rack grass separating plates 11. When picked grass is transferred from the picking rack grass separating plates 11 to the feeding base plate 21, the deformable portions 312 can undergo elastic deformation to allow relative movement between the picking device 1 and the feeding device 2.

[0034] Thus, after the spring teeth 12 of the picking device 1 pick up the grass on the ground, the grass that falls off the spring teeth 12 can be transported to the feeding device 2 through the grass blocking device 3. Since the grass blocking device 3 is connected to the picking device 1 and the feeding device 2 respectively, specifically the elastic base plate 31 is connected to the feeding base plate 21 of the feeding device 2 through its mounting portion 311 on the one hand, and is connected to the corresponding picking frame grass dividing plates 11 of the picking device 1 through its multiple deformation portions 312 on the other hand, it can effectively eliminate the gap between the picking device 1 and the feeding device 2, so that the grass is smoothly transported to the feeding device 2.

[0035] Furthermore, since the elastic bottom plate 31 of the grass-blocking prevention device 3 has a deformation portion 312 that can undergo elastic deformation, the deformation portion 312 can be elastically deformed during operation to adapt to the relative position change between the picking device 1 and the feeding device 2 (i.e., adapt to the floating of the picking device 1 relative to the feeding device 2 and the entire machine), thereby reducing or eliminating the conveying dead angle area between the picking device 1 and the feeding device 2, which is conducive to promoting the grass picked up by the picking device 1 to be conveyed to the feeding device 2, avoiding damage to working parts such as the spring teeth 12 due to accumulation and blockage, and improving the stability and reliability of the entire machine.

[0036] The mounting portion 311 and the plurality of deformable portions 312 of the elastic base plate 31 may be integrally formed from a metal plate (such as a spring steel plate), and the deformable portion 312 is formed as a cantilever structure extending from the mounting portion 311 and connected to the grass separating plate 11 of the picking frame, thereby allowing the picking device 1 and the feeding device 2 to move relative to each other by undergoing a certain elastic deformation. In other embodiments, the plurality of deformable portions 312 may be connected to the mounting portion 311 by welding or fasteners, so that the two may have different materials, or the mounting portion 311 may not necessarily be configured as a strip as shown in the figure, but may be formed as a plurality of independent elements that correspond to one or more deformable portions 312 and connect them to the feeding base plate 21.

[0037] In the illustrated preferred embodiment, the mounting portion 311 of the elastic base plate 31 is formed with a plurality of countersunk holes 311a, and the feed base plate 21 is correspondingly formed with a plurality of threaded holes. The elastic base plate 31 is connected to the feed base plate 21 via countersunk screws 4 that pass through the countersunk holes 311a and are screwed into the threaded holes. Thus, by allowing the screw heads of the countersunk screws 4 to sink into the countersunk holes 311a, they prevent them from protruding from the top surface of the elastic base plate 31, thereby preventing forage from being conveyed to the feeding device 2. In other embodiments, the elastic base plate 31 can also be connected to the feed base plate 21 by welding or other fastener connections.

[0038] Continue to refer to Figure 2 and Figure 3As shown, the deformation portion 312 of the elastic base plate 31 can be formed with a waist-shaped hole 312a extending from the mounting portion 311 toward the picking device 1, and can be connected to the corresponding picking frame grass separating plate 11 by respectively passing through the first bolt 5 of the waist-shaped hole 312a. For example, a threaded hole can be formed on the picking frame grass separating plate 11, and the first bolt 5 can pass through the waist-shaped hole 312a and be screwed to the threaded hole. Thus, during operation, not only can the deformation portion 312 itself be elastically deformed to adapt to the relative position change between the picking device 1 and the feeding device 2, but the deformation portion 312 can also be allowed to slide relative to the picking frame grass separating plate 11 along the direction from the mounting portion 311 toward the picking device 1 when deformed, so as to avoid structural damage caused by excessive deformation and better adapt to the relative position change between the picking device 1 and the feeding device 2. Among them, the first bolt 5 can be a hexagonal flange bolt, so that the connection between the deformation portion 312 and the picking frame grass separating plate 11 can be conveniently and reliably achieved. In addition, as shown in the figure, the elastic base plate 31 is connected so that its deformation portion 312 is located on the upper side of the picking rack grass dividing plate 11, which is conducive to utilizing the upper surface shape of the deformation portion 312 or the material guiding mechanism provided on the upper side of the deformation portion 312 as in the subsequent preferred embodiment to guide the grass to be smoothly transported to the feeding device 2.

[0039] Figure 4 and Figure 5 Shown is a perspective view and a partially enlarged view of a pick-up and feeding assembly for a baler according to another preferred embodiment of the present invention; Figures 6 to 8 The specific structure of the anti-grass blocking device 3 in the picking and feeding assembly is shown in different ways. Figure 4 and Figure 5 As shown, the pick-up feeding assembly of the preferred embodiment has the above-mentioned combination Figures 1 to 3 The described pick-up and feeding assemblies have essentially the same structure, comprising a pick-up device 1, a feeding device 2, and a grass-blocking prevention device 3 connected between the pick-up device 1 and the feeding device 2. The only difference between the two is that the grass-blocking prevention device 3 also includes a material guide mechanism 32 mounted on an elastic base plate 31. Therefore, the above description of the aforementioned preferred embodiment also applies to this preferred embodiment. The following will primarily detail the material guide mechanism 32 of the grass-blocking prevention device 3, and will not reiterate the other identical parts.

[0040] like Figures 6 to 8As shown, the guide mechanism 32 is mounted on the deformed portion 312 of the elastic base plate 31 and has an arc-shaped top surface for guiding the collected grass from the picking stand grass separating plate 11 to the feeding base plate 21. As the spring teeth 12 continuously pick up grass from the ground and transport it to the upper side of the picking stand grass separating plate 11, the grass is then squeezed and transported toward the feeding device 2. The arc-shaped top surface of the guide mechanism 32 guides the smooth transportation of the grass, preventing it from accumulating above the elastic base plate 31 and at its connection with the feeding base plate 21. Therefore, in order to have an appropriate amount of elastic deformation, the deformation portion 312 of the elastic base plate 31 can be bent and extended from its mounting portion 311 toward the picking device 1, and the material guiding mechanism 32 provides an upwardly arched arc-shaped top surface above the deformation portion 312 to guide the transportation of grass, so as to utilize the elastic deformation of the deformation portion to adapt to the relative position change between the picking device 1 and the feeding device 2, and further reduce or eliminate the transportation dead angle area between the picking device 1 and the feeding device 2.

[0041] The material guide mechanism 32 can be formed into a variety of suitable structural forms. In the preferred embodiment shown in the figure, the material guide mechanism 32 includes a contour plate 321 installed on the deformation part 312. The contour plate 321 is formed with an upwardly arched contour plate top surface as a part of the aforementioned arc-shaped top surface, and is spaced apart from the top surface of the deformation part 312 at both ends facing the grass separation plate 11 of the picking rack and the feeding bottom plate 21, as shown in FIG. Figure 8 As shown. Because the curved top surface of the material guide mechanism 32 is required to support and guide the forage during transportation, the profiling plate 321 is typically constructed with relatively high rigidity and wear resistance, such as carbon steel. However, if the profiling plate 321 were to contact the deformable portion 312 of the elastic base plate 31 over a relatively long length from the pickup device 1 toward the feeding device 2, this would adversely affect the elastic deformation of the deformable portion 312. To address this, the present invention arranges the front and rear ends of the profiling plate 321 to be spaced apart from the top surface of the deformable portion 312, with only the middle portion (such as the connecting portion 3211 of the profiling plate 321, described below) connecting to and contacting the top surface of the deformable portion 312 to minimize the impact on the elastic deformation of the deformable portion 312.

[0042] like Figure 6 and Figure 7As shown, in a preferred embodiment, the profiling plate 321 can be formed into a generally H-shaped structure, thereby comprising a connecting portion 3211 and profiling portions 3212 connected to both ends of the connecting portion 3211. The profiling portions 3212 form the aforementioned top surface of the profiling plate. It should be understood that although the profiling plate 321 is described herein as having distinct components for ease of explanation, the profiling plate 321 can be a single-piece component or a component connected by welding or other methods. The connecting portion 3211 of the profiling plate 321 can be formed with a mounting hole (not labeled), and the deformable portion 312 of the elastic base plate 31 can be formed with a threaded hole at a corresponding position. The profiling plate 321 can be connected to the elastic base plate 31 via a second bolt 6 that passes through the mounting hole and is screwed into the threaded hole. The second bolt 6 can be a hexagonal flange bolt, thereby conveniently and reliably connecting the profiling plate 321 to the elastic base plate 31.

[0043] As previously mentioned, by spacing the front and rear ends of the profiling plate 321 from the top surface of the deformable portion 312, the effects of elastic deformation on the deformable portion 312 can be effectively reduced. However, this can easily lead to failure of the connection between the profiling plate 321 and the deformable portion 312 due to the torque applied to the front and rear ends of the profiling plate 321. Furthermore, it can also easily cause forage to become stuck in the gap between the profiling plate 321 and the top surface of the deformable portion 312, hindering smooth forage transport. To this end, the illustrated preferred embodiment further includes front and rear buffers 322 and 323 connected to the front and rear ends of the profiling plate 321.

[0044] Specifically, if Figures 6 to 8 As shown, the material guide mechanism 32 further includes a front buffer 322 and a rear buffer 323. The front buffer 322 is connected to the end of the profiling plate 321 (such as its profiling portion 3212) facing the picking rack grass separating plate 11, and the rear buffer 323 is connected to the end of the profiling plate 321 (such as its profiling portion 3212) facing the feeding base plate 21. When assembled and in use, the front buffer 322 and the rear buffer 323 also respectively abut the top surface of the deformable portion 312. Therefore, during operation, the front buffer 322 and the rear buffer 323 can deform accordingly when the deformable portion 312 undergoes elastic deformation, thereby maintaining close contact with the deformable portion 312, utilizing their buffering properties to adapt to the deformation of the deformable portion 312, and reducing the risk of connection failure between the profiling plate 321 and the deformable portion 312. The front buffer 322 and the rear buffer 323 can each be made of rubber or other suitable elastic materials.

[0045] Furthermore, the front and rear buffer members 322 and 323 can each be formed with a front and rear buffer member top surface that is part of the aforementioned curved top surface. The front and rear buffer member top surfaces are flush with and adjacent to the top surface of the profiling plate. The front buffer member top surface can also be configured to extend from a position adjacent to the top surface of the profiling plate to a position adjacent to the top surface of the deformation portion 312. Thus, the front and rear buffer member top surfaces transition tangentially to the top surface of the profiling plate, preventing forage from being caught at the end of the profiling plate 321 facing the grass separating plate 11 of the picking rack, thereby ensuring that the forage is smoothly conveyed to the feeding device 2 along the curved top surface of the guide mechanism 32.

[0046] In the illustrated preferred embodiment, the rear buffer 323 further includes a partition portion located within the gap between the contour plate 321 and the top surface of the deformable portion 312. The front and rear buffers 322 and 323 can be connected to the contour plate 321 by appropriate means. For example, if the contour plate 321 is formed into an H-shaped structure having a connecting portion 3211 and a contour portion 3212, mounting holes can be formed in the front and rear buffers 322, 323, and contour portion 3212, respectively. Cross screws 7 can be passed through the mounting holes and tightened with nuts 8, thereby conveniently connecting the front and rear buffers 322 and 323 to the front and rear ends of the contour portion 3212, respectively. By configuring the material guide mechanism 32 to include the aforementioned contour plate 321, front buffer 322, and rear buffer 323, the forage can be conveyed along the arc segment of the front buffer top surface, driven by the movement of the spring teeth 12 and the action of the front buffer 322 (the top surface of the front buffer), to the arc segment of the contour plate top surface of the contour plate 321, and finally to the arc segment of the rear buffer top surface of the rear buffer 323, reaching the feeding device 2. During this process, the tips of the spring teeth gradually retract, from being exposed for a long time when passing through the front buffer 322 to being completely retracted to the bottom of the grass blocking device 3 when passing through the rear buffer 323, allowing the forage to fall off the spring teeth 12.

[0047] The present invention also provides a baler including the above-mentioned pick-up and feeding assembly. The baler can effectively ensure that the grass is transported from the pick-up device to the feeding device, avoid damage to working parts such as the spring teeth due to accumulation and blockage, and has high stability and reliability.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, the technical solution of the present invention may be subjected to a variety of simple modifications, including combining the various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
