Description

Technical Field

[0001] This utility model relates to the field of baler technology, and in particular to a dust removal structure for hay balers. Background Technology

[0002] A baler is an agricultural machine used to compress and bundle crop stalks or hay. It is mainly divided into two types: square balers and round balers. The former produces high-density square bales that are easy to stack and transport, while the latter is simple to operate and suitable for small and medium-sized farms. Its working principle is to collect straw through a pickup device, compress it, and then bundle it into bales. Balers significantly improve straw processing efficiency and are an important piece of equipment in modern agricultural production.

[0003] 1. Most dust removal structures used in balers rely on fans to draw diffused dust into a dust collection box for collection. However, during this process, hay can easily get caught inside the fan, affecting its performance. Existing solutions rely on a combination of filters and blades to address the hay problem. In actual use, even after cutting, some smaller hay pieces remain inside the filter. Over time, this accumulation reduces the airflow into the filter, impacting the device's efficiency and hindering dust collection.

[0004] 2. In existing technical solutions, during actual use, some dust still remains inside the filter and adheres to the top of the fan blades. Furthermore, due to the integrated design of the device, the filter and fan blades are not easily disassembled. Long-term dust accumulation affects the airflow into the filter; additionally, dust adhering to the top of the fan blades affects their rotational speed. In summary, the long-term impact of both factors negatively affects the overall performance of the device and is detrimental to its long-term use. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a dust removal structure for a hay baler.

[0007] The dust collection mechanism includes a fixed box, a suction fan installed at the rear of the fixed box, a connecting compartment fixedly connected to the front of the fixed box, and a cutting mechanism provided in front of the connecting compartment.

[0008] It also includes a cutting mechanism, which includes a housing, a feed hopper fixedly connected to the front of the housing, a transmission frame fixedly connected to the left side of the housing, a drive motor fixedly connected to the left side of the transmission frame, and a cutting blade capable of cutting forage installed inside the housing.

[0009] The fixed box has a sliding groove at the front of its interior. The front and rear sides of the fixed box are rotatably connected to the first stop block. A dust collection box is slidably connected to the left side of the fixed box. A one-way plate is rotatably connected to the front of the dust collection box. A slider is fixedly connected to the upper front side of the dust collection box. Support blocks are fixedly connected to the left and right sides of the interior of the dust collection box. A sliding frame is slidably connected to the interior of the dust collection box. A first filter screen is fixedly connected to the interior of the sliding frame. A cover is provided on the top of the dust collection box. A sealing block is fixedly connected to the bottom of the cover.

[0010] The slider is slidably connected to the slide groove, the slider is tightly fitted to the slide groove, the slide frame is slidably connected to the support block, the slide frame is tightly fitted to the support block, the slide frame is tightly fitted to the dust collection box, and the first stop block is tightly fitted to the dust collection box.

[0011] The cover is located inside the fixed box and fits tightly against the fixed box. The dust collection box is connected to the fixed box and to the suction fan.

[0012] The drive motor has a drive gear fixedly connected to its output end, a driven gear meshing below the drive gear, a cutting blade fixedly connected to the left side of the drive gear, and a cutting blade fixedly connected to the left side of the driven gear.

[0013] The second filter screen is fixedly connected to the rear of the box, the connecting box is fixedly connected to the bottom of the box, the collecting box is slidably connected inside the connecting box, and the second stop blocks are rotatably connected to the front and rear sides of the bottom of the connecting box.

[0016] This utility model provides a dust removal structure for a hay baler, which, compared to the prior art, has the following advantages:

[0017] 1. Compared with existing technologies, by setting up a second filter, dust can pass through the second filter and enter the interior of the connecting chamber and dust collection mechanism due to the blocking effect of the second filter. However, grass cannot pass through the interior of the second filter. The second filter is sloping. When the airflow blows into the interior of the dust collection mechanism, the grass will stick to the top of the second filter and will not penetrate the top of the second filter. When the grass accumulates to a certain amount, the suction fan is turned off in time. At this time, the grass will enter the interior of the collection box along the second filter. In this way, the second filter will not affect the airflow, so that the grass can be better processed and the airflow can be avoided due to the grass, thereby maintaining the efficiency of the overall device.

[0018] 2. Compared with existing technologies, when the amount of dust adhering to the first filter screen is too large, the operator can remove the sliding frame and the first filter screen at the same time, clean the first filter screen, and after the first filter screen is dried, reinstall the sliding frame and the first filter screen into the dust collection box. At this time, the first filter screen can filter dust while maintaining normal air flow, ensuring that the efficiency of the first filter screen will not decrease due to filter screen blockage. Moreover, the dust will not enter the interior of the suction fan due to the blocking effect of the first filter screen, and thus the dust will not adhere to the top of the fan blades in large quantities, thereby not affecting the rotation of the fan blades. This can avoid a large amount of dust accumulating on the top of the fan blades, and the filter screen can be replaced. This allows the device to be used for a long time without reducing its performance. Attached Figure Description

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The first embodiment of this application is as follows:

[0027] Please see Figures 1-4 The dust collection mechanism 1 includes a fixed box 11, a suction fan 12 is installed at the rear of the fixed box 11, a connecting chamber 2 is fixedly connected to the front of the fixed box 11, a cutting mechanism 3 is provided in front of the connecting chamber 2, and the cutting mechanism 3 includes a box body 31, a feed hopper 4 is fixedly connected to the front of the box body 31, a transmission frame 32 is fixedly connected to the left side of the box body 31, a drive motor 33 is fixedly connected to the left side of the transmission frame 32, and a cutting blade 36 capable of cutting forage is installed inside the box body 31.

[0028] The above structure, by providing a connecting compartment 2, enables the connection between the fixed box 11 and the box body 31. The provision of a feed hopper 4 allows the airflow to carry dust through the feed hopper 4 into the interior of the overall device.

[0029] The fixed box 11 has a sliding groove 13 at the front of its interior. The front and rear sides of the fixed box 11 are rotatably connected to the first stop block 14. A dust collection box 15 is slidably connected to the left side of the fixed box 11. A one-way plate 16 is rotatably connected to the front of the dust collection box 15. A slider 17 is fixedly connected to the upper front side of the dust collection box 15. Support blocks 18 are fixedly connected to the left and right sides of the interior of the dust collection box 15. A sliding frame 19 is slidably connected inside the dust collection box 15. A first filter screen 110 is fixedly connected inside the sliding frame 19. A cover 11 is provided on the top of the dust collection box 15. 1. A sealing block 112 is fixedly connected to the lower part of the cover 111. The slider 17 is slidably connected to the slide groove 13 and the slider 17 is tightly fitted to the slide groove 13. The slide frame 19 is slidably connected to the support block 18 and the slide frame 19 is tightly fitted to the support block 18. The slide frame 19 is tightly fitted to the dust collection box 15. The first stop block 14 is tightly fitted to the dust collection box 15. The cover 111 is located inside the fixed box 11 and the cover 111 is tightly fitted to the fixed box 11. The dust collection box 15 is connected to the fixed box 11 and the dust collection box 15 is connected to the suction fan 12.

[0030] The above structure, driven by the suction fan 12, allows the air to carry dust and hay into the interior of the cutting mechanism 3 and the dust collection mechanism 1.

[0031] By incorporating a one-way deflector 16, when the suction fan 12 is turned on, the deflector 16 rotates upwards and backwards under the force of the airflow, allowing dust and airflow to enter the dust collection box 15. When the suction fan 12 is turned off, the deflector 16 rotates downwards under its own weight, closing the deflector 16 and the dust collection box 15. This prevents dust from flowing out of the dust collection box 15 through the deflector 16, effectively avoiding dust backflow.

[0032] By rotating the first stop 14 on both the front and rear sides to prevent it from obstructing the dust collection box 15, the operator can hold the handle on the left side of the dust collection box 15 and remove the entire dust collection box 15, thus facilitating the centralized treatment of the dust inside the dust collection box 15.

[0033] A first filter 110 is fixedly connected inside the sliding frame 19, and the sliding frame 19, support block 18, and dust collection box 15 are slidably connected simultaneously. This allows the operator to remove the sliding frame 19 and the first filter 110 simultaneously when the amount of dust attached to the first filter 110 is too large, clean the first filter 110, and reinstall the sliding frame 19 and the first filter 110 into the dust collection box 15 after the first filter 110 has dried. This allows the first filter 110 to filter dust while maintaining normal airflow, ensuring that the efficiency of the first filter 110 will not decrease due to filter blockage. Furthermore, the dust will not enter the interior of the suction fan 12 due to the obstruction of the first filter 110, and thus dust will not adhere to the top of the fan blades in large quantities, thereby not affecting the rotation of the fan blades and effectively maintaining the overall operating efficiency of the device.

[0034] By incorporating a sealing block 112 that fits tightly against the dust collection box 15, and by ensuring the cover 111 fits tightly against the fixed box 11, the sealing block 112 remains inside the dust collection box 15 after it is inserted into the fixed box 11. The sealing block 112 prevents gas from flowing out from the top of the dust collection box 15, maintaining the airtightness of the dust collection box 15 at the point where airflow is not possible.

[0035] The second embodiment of this application is as follows:

[0036] Please see Figures 1-4 Based on the first embodiment, the output end of the drive motor 33 is fixedly connected to a drive gear 34, a driven gear 35 meshes below the drive gear 34, a cutting blade 36 is fixedly connected to the left side of the drive gear 34, a cutting blade 36 is fixedly connected to the left side of the driven gear 35, a second filter screen 37 is fixedly connected to the rear of the housing 31, a connecting box 38 is fixedly connected to the lower part of the housing 31, a collection box 39 is slidably connected inside the connecting box 38, and second stops 310 are rotatably connected to the front and rear sides below the connecting box 38. The drive gear 34 is rotatably connected to the transmission frame 32, the driven gear 35 is rotatably connected to the transmission frame 32, the cutting blade 36 is rotatably connected to the housing 31, the housing 31 is fixedly connected to the connecting chamber 2, the housing 31 is connected to the connecting box 38, the housing 31 is connected to the collection box 39, and the second stops 310 are tightly fitted to the collection box 39.

[0037] In the above structure, driven by the drive motor 33, the driving gear 34 rotates. A driven gear 35 meshes with the lower part of the driving gear 34. A cutting blade 36 is fixedly connected to the left side of the driving gear 34, and the cutting blade 36 is fixedly connected to the left side of the driven gear 35. This allows the driving gear 34 and driven gear 35 to drive the cutting blade 36 on the left side to rotate. The staggered arrangement of the cutting blades 36 on the upper and lower sides allows them to cut longer hay, ensuring that all hay can enter the collection box 39.

[0038] By providing a second filter 37, dust can pass through the second filter 37 and enter the interior of the connecting chamber 2 and the dust collection mechanism 1. However, grass cannot pass through the interior of the second filter 37, which is sloped. When the airflow blows into the dust collection mechanism 1, the grass will adhere to the top of the second filter 37 and will not penetrate it. When the grass accumulates to a certain amount, the fan 12 is turned off, and the grass enters the collection box 39 along the second filter 37. This ensures that the second filter 37 does not affect the airflow and maintains the working efficiency of the device.

[0039] Working principle: This dust removal structure for hay balers works by first turning on the suction fan 12. Driven by the suction fan 12, airflow is directed towards the cutting mechanism 3, connecting chamber 2, and dust collection mechanism 1. During this movement, the airflow carries dust and a small amount of hay into the machine. The hay is cut into small pieces by the cutting mechanism 3 and fits against the second filter 37. The operator only needs to turn the suction fan 12 off and on as needed. The hay will then enter the collection box 39. The dust will pass through the second filter 37 and eventually enter the dust collection box 15. Blocked by the first filter 110, the dust will remain inside the dust collection box 15, thus completing the dust removal process.

[0040] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
