Description

Technical Field

[0001] The utility model relates to the technical field of agricultural and animal husbandry machinery, in particular to a straw bale density adjusting mechanism for a round baler. Background Art

[0002] In the round balers widely used in agriculture and animal husbandry, the regulation of the straw bale density has an important impact on the baling quality and operation efficiency. Traditional round balers mostly use a hydraulic system to control the straw bale density. As the straw bale expands continuously in the bin, pressure is generated and transmitted to the bin oil cylinder, and the pressure value is displayed by a pressure gauge.

[0003] The existing patent (publication number: CN209403086U) proposes a straw bale density adjusting mechanism for a round baler, which mainly includes a fixed spring, a pull rod, a position sensor, a fixed rod, an induction plate, a rotary rod, a hook spring, a steel wire rope group, a rotating connecting rod, a hook spring plate, a pressure rod, a compression spring, a frame fixed shaft, a lock pin arm, a hook, an accumulator and a bin closing oil cylinder. The lock pin arm, the accumulator and the bin closing oil cylinder are installed on the rear bin.

[0004] This utility model realizes the mechanical control of a straw bale density adjusting mechanism for a round baler, ensuring that the rear bin is in a locked state during the working process of the round baler, and has the characteristics of simple structure, reliable performance and wide application range.

[0005] However, in actual use, there are still the following deficiencies. For example, in the above patent, through the fixed spring, the pull rod, the position sensor, the fixed rod, the induction plate, the rotary rod, the hook spring, the steel wire rope group, the rotating connecting rod and the hook spring plate, it is ensured that the rear bin is in a locked state during the working process of the round baler, which cannot meet the requirement that the equipment can automatically adjust the compaction density of the forage, resulting in inconsistent internal density of the straw bale and affecting the forming quality of the straw bale. The inflexible adjustment of the straw bale density will lead to a reduction in the working speed of the baler and affect the operation efficiency. Therefore, this utility model proposes a straw bale density adjusting mechanism for a round baler to solve the above problems. Summary of the Utility Model

[0006] The purpose of this utility model is to solve the deficiencies existing in the prior art and propose a straw bale density adjusting mechanism for a round baler.

[0007] To achieve the above purpose, this utility model adopts the following technical scheme: A straw bale density adjusting mechanism for a round baler includes a fixed seat. A material guiding groove is opened on the fixed seat. A pressing assembly is arranged on the fixed seat. A lifting assembly is arranged on one side of the fixed seat close to the pressing assembly. A pressure trigger assembly is arranged on the pressing assembly. An outlet hole is opened on one side of the fixed seat;

[0008] The pressing assembly includes a hydraulic rod and a fixed block. A moving block is fixed to the output end of the hydraulic rod. A first pressing plate is rotatably connected to the moving block. A rotating rod is rotatably connected to the fixed block. A first fixing column is fixed to one end of the rotating rod. A second fixing column is rotatably connected to the other end of the rotating rod. A second pressing plate is fixed to the second fixing column;

[0009] The lifting assembly includes a support plate, a transmission motor and a support seat. A first gear is fixed to the output end of the transmission motor. A second gear is rotatably connected inside the support seat. A first support rod is fixed to the second gear. A second support rod is rotatably connected to the first support rod. The second support rod is rotatably connected to the support plate. A telescopic rod is movably connected to the first support rod. A scale is slidably connected to the support plate.

[0010] As a preferred embodiment, the hydraulic rod is installed on the support plate, the fixed block is fixed on the fixed seat, a chute is opened on the moving block, a slider is fixed to one side of the fixed seat close to the chute, and the slider is slidably connected inside the chute.

[0011] The beneficial effect of adopting the above further scheme is that: since the hydraulic rod is installed on the support plate, the support plate can provide a supporting and fixing effect on the hydraulic rod. Since the fixed block is fixed on the fixed seat, the fixed seat can provide a supporting and fixing effect on the fixed block. Since a chute is opened on the moving block, a slider is fixed to one side of the fixed seat close to the chute, and the slider is slidably connected inside the chute, the chute and the slider can play a limiting role in the movement of the moving block when the moving block moves.

[0012] As a preferred embodiment, the transmission motor is installed on the fixed seat, the support seat is fixed on the fixed seat, one side of the scale is fixed on the fixed seat, and one end of the limiting rod is fixed on the fixed seat.

[0013] The beneficial effect of adopting the above further scheme is that: since the transmission motor is installed on the fixed seat, the fixed seat can provide a supporting and fixing effect on the transmission motor. Since the support seat is fixed on the fixed seat, the support seat can be rotatably connected to the support seat. Since one side of the scale is fixed on the fixed seat, and one end of the limiting rod is fixed on the fixed seat, the fixed seat can provide a supporting and fixing effect on the scale and the limiting rod.

[0014] As a preferred embodiment, the pressure trigger assembly includes a third pressing plate. A push rod is fixed to the third pressing plate. The push rod is slidably connected inside the second fixing column and the second pressing plate. A telescopic spring is arranged on the push rod.

[0015] The beneficial effects of adopting the above further solution are as follows: Since the push rod is fixed on the third pressing plate, when the third pressing plate moves, it can push the push rod to move inward. Since the push rod is slidably connected in the second fixing column and the second pressing plate, the push rod can slide in the second fixing column and the second pressing plate. Since the telescopic spring is arranged on the push rod, through the elastic force of the telescopic spring, the third pressing plate can rebound to its original position.

[0016] As a preferred embodiment, one end of the telescopic spring is fixedly connected to the third pressing plate, the other end of the telescopic spring is fixedly connected to the second fixing column, and a trigger button is arranged in the second fixing column.

[0017] The beneficial effects of adopting the above further solution are as follows: By arranging the third pressing plate, when the second pressing plate presses the forage, when the pressing force is too large, the third pressing plate will push the push rod to move inward until the trigger button is pressed, so that the trigger button transmits a signal to the driving motor, thereby causing the lifting assembly to lift the support plate, thereby reducing the pressing degree of the pressing assembly on the forage.

[0018] As a preferred embodiment, a wire outlet hole is formed on one side of the fixing seat close to the trigger button.

[0019] The beneficial effects of adopting the above further solution are as follows: By arranging the wire outlet hole, the wiring on the trigger button can be connected to the outside through the wire outlet hole.

The second gear is connected to the first support rod, so the first support rod will also rotate accordingly. The first support rod is connected to the second support rod, so the second support rod will also rotate accordingly. The rotation of the second support rod can control the height of the support plate. When the second support rod rotates upward, the support plate will rise, so that the hydraulic rod will also rise accordingly. On the contrary, when the second support rod rotates downward, the support plate will descend, so that the hydraulic rod will also descend accordingly. In this way, the height of the support plate can be accurately adjusted, thereby controlling the position of the hydraulic rod. A scale is arranged on the support plate, and the operator can accurately adjust the height of the support plate by observing the scale, thereby controlling the density of the hay bale to be pressed. When the support plate reaches the appropriate height, the operator starts the hydraulic rod, the output end of the hydraulic rod pushes the moving block, so that the moving block drives the rotating rod to rotate, and the rotation of the rotating rod will cause the first pressing plate and the second pressing plate to press the forage, thus solving the technical problem of controlling the pressing density of the forage before hay baling.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figures 1-4 shown, this embodiment provides a technical solution: a bale density adjustment mechanism for a round bale baler, including a fixed seat 1, a material guiding groove 2 is opened on the fixed seat 1, a pressing component 3 is arranged on the fixed seat 1, a lifting component 4 is arranged on one side of the fixed seat 1 close to the pressing component 3, a pressure trigger component 5 is arranged on the pressing component 3, and a wire outlet hole 6 is opened on one side of the fixed seat 1;

[0034] As Figures 1-2 shown, the pressing assembly 3 includes a hydraulic rod 31 and a fixed block 36. A moving block 32 is fixed to the output end of the hydraulic rod 31. A first pressing plate 35 is rotatably connected to the moving block 32. A rotating rod 37 is rotatably connected to the fixed block 36. A first fixing column 38 is fixed to one end of the rotating rod 37. The other end of the rotating rod 37 is rotatably connected to a second fixing column 39. A second pressing plate 310 is fixed to the second fixing column 39;

[0035] As Figure 1 and Figure 3 shown, the lifting assembly 4 includes a support plate 41, a transmission motor 42 and a support base 44. A first gear 43 is fixed to the output end of the transmission motor 42. A second gear 45 is rotatably connected inside the support base 44. A first support rod 46 is fixed to the second gear 45. A second support rod 47 is rotatably connected to the first support rod 46. The second support rod 47 is rotatably connected to the support plate 41. A telescopic rod 48 is movably connected to the first support rod 46. A scale 49 is slidably connected to the support plate 41. A limiting rod 410 is slidably connected to the support plate 41. When the operator starts the transmission motor 42, the output end of the transmission motor 42 drives the first gear 43 to rotate. The first gear 43 meshes with the second gear 45, causing the second gear 45 to rotate accordingly. The second gear 45 is connected to the first support rod 46, so the first support rod 46 will also rotate accordingly. The first support rod 46 is connected to the second support rod 47, so the second support rod 47 will also rotate accordingly. The rotation of the second support rod 47 can control the height of the support plate 41. When the second support rod 47 rotates upward, the support plate 41 will rise, causing the hydraulic rod 31 to rise accordingly. Conversely, when the second support rod 47 rotates downward, the support plate 41 will descend, causing the hydraulic rod 31 to descend accordingly. In this way, the height of the support plate 41 can be precisely adjusted, thereby controlling the position of the hydraulic rod 31. A scale 49 is provided on the support plate 41, and the operator can precisely adjust the height of the support plate 41 by observing the scale 49, thereby controlling the density of the hay bales to be pressed. When the support plate 41 reaches the appropriate height, the operator starts the hydraulic rod 31. The output end of the hydraulic rod 31 pushes the moving block 32, causing the moving block 32 to drive the rotating rod 37 to rotate. The rotation of the rotating rod 37 causes the first pressing plate 35 and the second pressing plate 310 to press the forage, thus solving the technical problem of controlling the pressing density of the forage before baling.

[0036] In the above solution, there is also a problem that when the pressure of the pressing assembly 3 on the forage is too large, it cannot meet the requirement of automatic alarm to reduce the pressure on the forage. As Figure 2As shown in the figure: The hydraulic rod 31 is installed on the support plate 41, the fixed block 36 is fixed on the fixed seat 1, a sliding groove 33 is formed on the moving block 32, a slider 34 is fixed on one side of the fixed seat 1 close to the sliding groove 33, and the slider 34 is slidably connected in the sliding groove 33. Since the hydraulic rod 31 is installed on the support plate 41, the support plate 41 can provide a supporting and fixing effect on the hydraulic rod 31. Since the fixed block 36 is fixed on the fixed seat 1, the fixed seat 1 can provide a supporting and fixing effect on the fixed block 36. Since the moving block 32 is provided with the sliding groove 33, the slider 34 is fixed on one side of the fixed seat 1 close to the sliding groove 33, and the slider 34 is slidably connected in the sliding groove 33, the sliding groove 33 and the slider 34 can play a limiting role in the movement of the moving block 32 when the moving block 32 moves;

[0037] As Figure 1 and Figure 3 shown in the figure, the transmission motor 42 is installed on the fixed seat 1, the support seat 44 is fixed on the fixed seat 1, one side of the scale 49 is fixed on the fixed seat 1, and one end of the limiting rod 410 is fixed on the fixed seat 1. Since the transmission motor 42 is installed on the fixed seat 1, the fixed seat 1 can provide a supporting and fixing effect on the transmission motor 42. Since the support seat 44 is fixed on the fixed seat 1, the support seat 44 can be rotatably connected to the support seat 44. Since one side of the scale 49 is fixed on the fixed seat 1, and one end of the limiting rod 410 is fixed on the fixed seat 1, the fixed seat 1 can provide a supporting and fixing effect on the scale 49 and the limiting rod 410;

[0038] As Figure 1 and Figure 4 shown in the figure, the pressure trigger assembly 5 includes a third pressing plate 51, a push rod 52 is fixed on the third pressing plate 51, the push rod 52 is slidably connected in the second fixed column 39 and the second pressing plate 310, and a telescopic spring 53 is arranged on the push rod 52. Since the push rod 52 is fixed on the third pressing plate 51, the third pressing plate 51 can push the push rod 52 to move inward when moving. Since the push rod 52 is slidably connected in the second fixed column 39 and the second pressing plate 310, the push rod 52 can slide in the second fixed column 39 and the second pressing plate 310. Since the push rod 52 is provided with the telescopic spring 53, through the elastic force of the telescopic spring 53, the third pressing plate 51 can rebound to its original position. One end of the telescopic spring 53 is fixedly connected to the third pressing plate 51, the other end of the telescopic spring 53 is fixedly connected to the second fixed column 39, and a trigger button 54 is arranged in the second fixed column 39. By arranging the third pressing plate 51, when the second pressing plate 310 squeezes the forage, when the squeezing force is too large, the third pressing plate 51 will push the push rod 52 to move inward until the trigger button 54 is pressed, so that the trigger button 54 transmits a signal to the transmission motor 42, thereby causing the lifting assembly 4 to lift the support plate 41, thereby reducing the pressing degree of the pressing assembly 3 on the forage;

[0039] As Figures 1-2 shown, a wire outlet hole 6 is provided on one side of the fixed seat 1 close to the trigger button 54. Through the provided wire outlet hole 6, the wiring on the trigger button 54 can be connected to the outside through the wire outlet hole 6.

[0040] Working principle:

[0041] As Figures 1-4 shown, first, the operator starts the drive motor 42. The output end of the drive motor 42 drives the first gear 43 to rotate. The first gear 43 meshes with the second gear 45, causing the second gear 45 to rotate accordingly. The second gear 45 is connected to the first support rod 46, so the first support rod 46 will also rotate accordingly. The first support rod 46 is connected to the second support rod 47, so the second support rod 47 will also rotate accordingly. The rotation of the second support rod 47 can control the height of the support plate 41. When the second support rod 47 rotates upward, the support plate 41 will rise, causing the hydraulic rod 31 to rise accordingly. Conversely, when the second support rod 47 rotates downward, the support plate 41 will descend, causing the hydraulic rod 31 to descend accordingly. In this way, the height of the support plate 41 can be accurately adjusted to control the position of the hydraulic rod 31. A scale 49 is provided on the support plate 41, and the operator can accurately adjust the height of the support plate 41 by observing the scale 49 to control the density of the hay bale to be compacted. When the support plate 41 reaches the appropriate height, the operator starts the hydraulic rod 31. The output end of the hydraulic rod 31 pushes the moving block 32, causing the moving block 32 to drive the rotating rod 37 to rotate. The rotation of the rotating rod 37 causes the first pressing plate 35 and the second pressing plate 310 to compact the forage. Through the provided third pressing plate 51, when the second pressing plate 310 squeezes the forage and the squeezing force is too large, the third pressing plate 51 will push the push rod 52 to move inward until the trigger button 54 is pressed, causing the trigger button 54 to transmit a signal to the drive motor 42, thereby causing the lifting assembly 4 to lift the support plate 41, reducing the compaction degree of the compaction assembly 3 on the forage.

[0042] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
