The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] like Figures 1 to 7 As shown, the present application provides a forage baling device, comprising: a base 1, a bracket 2, a net cylinder 4, a forming box 3 and an extrusion mechanism, wherein the bracket 2 is arranged on the base 1; the net cylinder 4 is detachably arranged on the base 1, and the net cylinder 4 is arranged vertically; the forming box 3 is movably connected to the base 1, and in the vertical direction, both ends of the forming box 3 are openings, and the net cylinder 4 is located in the forming box 3, and a storage chamber 33 is formed between the net cylinder 4 and the forming box 3; the extrusion mechanism comprises a first driving assembly and an extrusion plate 6, the first driving assembly is arranged on the bracket 2, and moves up and down in the vertical direction; the extrusion plate 6 is arranged at an end of the first driving assembly away from the bracket 2, the shape of the extrusion plate 6 is adapted to the opening of the forming box 3, and the extrusion plate 6 is provided with an avoidance hole 61, and the avoidance hole 61 is arranged corresponding to the net cylinder 4; the first driving assembly drives the extrusion plate 6 to extend into the forming box 3, and the upper end of the net cylinder 4 passes through the avoidance hole 61.

[0027] Specifically, the base 1 is located at the bottom of the forage baling device, providing a stable operating platform for the entire forage baling device. The bracket 2 is fixedly mounted on the upper end of the base 1, used to support and install other functional components, and plays a key role in bearing weight and connecting various parts. For example, the bracket 2 is set in an n-shape. The forming box 3 is movably connected to the upper surface of the base 1, and both the upper and lower ends are open to facilitate the entry of forage and the output of finished bales. The forming box 3 can be moved or flipped on the base 1 to adapt to different working conditions, so that the formed forage bales can be moved out of the forming box 3. The net cylinder 4 is arranged inside the forming box 3, and is detachably connected to the upper end surface of the base 1, which is convenient for maintenance and replacement. The area between the net cylinder 4 and the forming box 3 forms a storage chamber 33 for accommodating the forage to be baled. The extrusion mechanism includes a first drive assembly and an extrusion plate 6. The first drive assembly is mounted on the bracket 2 and is responsible for providing a power source, including but not limited to components such as a motor 75, a hydraulic cylinder or a pneumatic cylinder. The squeezing plate 6 is provided with an avoidance hole 61 for use with the net cylinder 4 and is fixed at the end of the first driving assembly away from the bracket 2. The size and shape of the squeezing plate 6 match the storage chamber 33 to ensure that the forage in the storage chamber 33 can be effectively compressed and baled. When working, the first driving assembly drives the squeezing plate 6 to reciprocate up and down in the vertical direction. When the squeezing plate 6 moves downward, the forage in the storage chamber 33 is strongly squeezed to make it compact into a bundle; when the squeezing plate 6 moves upward, the pressure is released to facilitate the next filling cycle or the removal of the bale.

[0028] The working process is as follows:

[0029] First, the net cylinder 4 is installed inside the forming box 3 and fixed on the base 1, and a space for storing forage, namely, the storage chamber 33, is formed between the net cylinder 4 and the forming box 3. The scattered forage is collected and sent into the storage chamber 33 by manual or mechanical means. The first drive assembly is started to drive the extrusion plate 6 to move downward in the vertical direction. At this time, the net cylinder 4 will pass through the avoidance hole 61 opened on the extrusion plate 6, so that the extrusion plate 6 compresses the forage in the storage chamber 33. Because of the existence of the net cylinder 4, the forage will not accumulate to the center of the bale during the compression process, thereby forming a hollow structure. In this process, the operator needs to timely control the first drive assembly to make it move up and down repeatedly to ensure that the forage can be filled into the storage chamber 33 in batches and layer by layer, and is fully compacted after each downward pressure to achieve the effect of reducing the volume and increasing the density. In the continuous baling process, it is crucial to ensure that each newly added forage can be tightly bonded to the compacted part to form a very dense bale. When the bale is compressed to a preset degree, the first drive assembly drives the squeezing plate 6 to rise, and at the same time, the forming box 3 is moved away through other drive mechanisms to separate it from the formed bale. In the last step, the staff takes out the compacted bale and the net tube 4 from the base 1, and the baling process of a single bale of forage grass is completed. By repeating the above steps, the entire baling task of forage grass can be successfully completed.

[0030] The above technical solution adopted by the photovoltaic power station water filtration and anti-blocking device provided in this application can achieve the following beneficial effects:

[0031] (1) The net tube 4 is arranged inside the forming box 3, and a storage chamber 33 is formed between the net tube 4 and the forming box 3; and an avoidance hole 61 matching the net tube 4 is arranged on the extrusion plate 6; when the grass is baled and compressed into a bale, the net tube 4 will extend into the avoidance hole 61 and occupy the central part of the bale, so that a hollow structure is formed inside the bale, and the net tube itself is wrapped in the middle of the bale and is not taken out, which constitutes a unique ventilation system. Air can freely enter and exit the bale through the net tube, so that the moisture inside the bale can be effectively discharged. At the same time, the fresh air outside can also smoothly enter the bale, realizing the continuous renewal of the air inside the bale. In this way, the overall air permeability of the bale is greatly enhanced, which is conducive to reducing the moldy phenomenon of grass caused by moisture accumulation, and thus the baled grass can be stored for a long time without being easily deteriorated.

[0032] (2) The split design of the base 1, the bracket 2, the forming box 3 and the net cylinder 4 makes the equipment easy to assemble, disassemble and maintain, and it is also convenient to adjust the position and replace the worn parts as needed.

[0033] In a preferred embodiment, at least two clamping strips 8 are provided on the base 1 , and the net cylinder 4 is detachably connected to the clamping strips 8 .

[0034] Specifically, the base 1 is provided with at least two upwardly inclined clips 8 at its upper end portion, the clips 8 including a welding portion and a free end portion, and the inclination angle is not more than 10 o . For example, three clamping strips 8 are provided, and the intervals between the clamping strips 8 are equal, and they are evenly distributed along the circumference of the net tube 4, and all are located on one side of the semicircle of the net tube 4. The clamping strip 8 can be designed to be an isosceles triangle shape, and its short side is fixed to the base 1 by welding, and the tip portion extends toward the direction of the net tube 4. Such a layout is conducive to providing balanced and stable support and restraint, and can be easily removed. When implementing the snap-fit ​​connection operation, the portion of the clamping strip 8 that extends obliquely upward will be inserted into the internal cavity of the net tube 4. At the same time, the edge of the net tube 4 will accurately press against the place where the clamping strip 8 is welded to the base 1, forming a strong contact and fixing effect, ensuring that the net tube 4 does not shake or detach during operation, thereby improving the structural stability and safety of the entire device.

[0035] Once baling is completed, the net drum 4 together with the bale can be smoothly moved out from the direction of the tip of the clamping strip 8, and then the next round of baling can be carried out. By setting the clamping strip 8, it is ensured that the net drum 4 can still remain firmly positioned under the action of squeezing and other forces, and effectively prevent the net drum 4 from shifting or detaching due to machine vibration or external impact; secondly, it improves the stability and reliability of the overall operation of the equipment, and also greatly speeds up the installation and removal speed of the net drum 4, thereby improving the work efficiency of the entire baling process.

[0036] In a more preferred embodiment, the height of the mesh cylinder 4 is smaller than the height of the forming box 3 .

[0037] In actual operation, as the first driving assembly continuously rises and falls, the forage is synchronously filled into the forming box 3 to ensure that the height of the formed bale is exactly level with the net tube 4. Such a design not only makes the appearance of the bale more regular, and the bales will not interfere with each other due to the extended part of the net tube 4, but also greatly improves the stacking stability and facilitates the handling of the bales.

[0038] In a preferred embodiment, the first driving assembly includes at least two jacks 5 , one end of the jack 5 is connected to the extrusion plate 6 , and one end of the jack 5 away from the extrusion plate 6 is connected to the bracket 2 .

[0039] Specifically, the first driving component includes at least two hydraulic or mechanical jacks 5, which can realize the up and down movement of the pressing plate 6 through the telescopic movement of the telescopic rod. One end of each jack 5 is connected to the pressing plate 6 through a mechanical connector (such as a bolt, a hinge or a special connecting seat), and the end far away from the pressing plate 6 is also connected to the bracket 2 in a similar connection manner. By setting the jacks 5, the lifting movement of the pressing plate 6 relative to the bracket 2 is regulated, so that the pressing plate 6 can strongly compress the forage in the forming box 3. At the same time, the jacks 5 are fixed by the bracket 2, ensuring their stability and safety during the working process.

[0040] Based on the above implementation scheme, in order to ensure the balance and uniformity during the pressing process and avoid problems such as tilting and distortion of the pressing plate 6 caused by uneven force, the jacks 5 are symmetrically arranged on the axis of the pressing plate 6. For example, two jacks 5 are set and arranged on the central axis of the pressing plate 6, and are symmetrically arranged on both sides of the pressing plate 6. During operation, the two jacks 5 drive the pressing plate 6 to move up and down reciprocally at the same time. The symmetrical arrangement can effectively disperse the load, avoid problems such as tilting or partial load caused by excessive force on one side, ensure that the pressing plate 6 always maintains balance during the lifting process, improve the smoothness and safety of the entire pressing process, and improve the working efficiency of the equipment and the quality of the hay bales.

[0041] In a preferred implementation scheme, the forming box 3 includes a U-shaped frame 32 and a blocking plate 31. The U-shaped frame 32 is slidably connected to the base 1, the blocking plate 31 is fixed on the base 1, and the U-shaped frame 32 slides between a first position and a second position. In the first position, the U-shaped frame 32 is docked with the blocking plate 31, and in the second position, the U-shaped frame 32 is away from the blocking plate 31.

[0042] Specifically, the forming box 3 is mainly composed of two parts, namely a U-shaped frame 32 and a blocking plate 31. Among them, the blocking plate 31 is fixed at the upper end position of the base 1; two parallel chutes are provided at the upper end of the base 1. The opposite two side edges at the bottom end of the U-shaped frame 32 extend downward into the chutes and are slidably connected with the chutes, and can move along a preset track. The two parallel chutes preset on the base 1 not only provide a sliding path for the U-shaped frame 32, but also effectively constrain and guide its movement. After the two side edges at the bottom end of the U-shaped frame 32 are inserted into the chutes, it can smoothly slide along the chutes, ensuring the accuracy and stability of the movement of the U-shaped frame 32 during the entire working process. During the hay bale forming stage, the U-shaped frame 32 is closely docked with the blocking plate 31 to form a bundling space to compress the forage and form a tight hay bale. And during the hay bale unloading stage, the U-shaped frame 32 slides away from the blocking plate 31, expanding the internal space, facilitating the smooth removal of the formed hay bale, and completing the output of the hay bale.

[0043] Further optimize the above solution. At the first position, the C-shaped frame 32 and the plugging plate 31 are connected in an embedded manner.

[0044] Specifically, two parallel strip-shaped grooves are formed on the side surface of the plugging plate 31 close to the C-shaped frame 32. The dimensions of the strip-shaped grooves match the corresponding parts of the C-shaped frame 32, so that the C-shaped frame 32 can be accurately and firmly embedded into the strip-shaped grooves. By embedding the C-shaped frame 32 into the strip-shaped grooves on the plugging plate 31, a strong mechanical connection is formed between the two, which can effectively transmit and disperse the force, improve the structural strength of the connection part, and avoid fracture or damage caused by uneven force. At the same time, the C-shaped frame 32 is not prone to relative movement or detachment, and can remain stable even under large external forces or vibrations, thereby enhancing the stability of the overall structure.

[0045] Further optimize this structure. A second driving assembly 7 is drivingly connected to the side of the C-shaped frame 32 away from the plugging plate 31. One end of the second driving assembly 7 away from the C-shaped frame 32 is cooperatively connected to the support 2. The second driving assembly 7 includes, but is not limited to, transmission methods such as gears, racks, hydraulic pressure, pneumatic pressure, or electric push rods. The C-shaped frame 32 is fixedly installed on its side背离 the plugging plate 31 through a specific connection method, which may be any one or a combination of various mechanical connection means such as welding, bolt fastening, snap connection, hinge connection, keyway fit, etc. One end of the second driving assembly 7 away from the C-shaped frame 32 is cooperatively connected to the support 2. By setting the second driving assembly 7, the sliding of the C-shaped frame 32 can be effectively driven.

[0046] Based on the above implementation scheme, the second driving assembly 7 includes a support sliding plate 73, a rack 72, a support seat 74, a motor 75, and a gear 71. The support seat 74 is arranged on the base 1, the motor 75 is arranged on the support seat 74, the gear 71 is drivingly connected to the motor 75, the support 2 is provided with an avoidance sliding hole 21, one end of the support sliding plate 73 is connected to the C-shaped frame 32, the other end passes through the avoidance sliding hole 21, and the avoidance sliding hole 21 is slidably matched with the support sliding plate 73. The rack 72 is arranged on the support sliding plate 73 and meshes with the gear 71.

[0047] Specifically, the support base 74 is fixed on the base 1, providing a stable installation foundation for the motor 75 to ensure that the motor 75 does not shake or shift during operation. The motor 75 is drivingly connected to the gear 71 through the rotating shaft 76. When the motor 75 operates, the gear 71 can be driven to rotate by the rotating shaft 76. An avoidance sliding hole 21 is formed in the bracket 2. One end of the support sliding plate 73 is connected to the U-shaped frame 32, and the other end slides in the avoidance sliding hole 21 to form a linear reciprocating motion, enabling the support sliding plate 73 to move stably in the avoidance sliding hole 21. The rack 72 is fixed on the support sliding plate 73. As the support sliding plate 73 slides, the rack 72 always remains in meshing with the gear 71 at a fixed position. When the motor 75 drives the gear 71 to rotate, due to the meshing effect between the gear 71 and the rack 72, the support sliding plate 73 is driven to move linearly along the avoidance sliding hole 21, thereby controlling the position or movement of the U-shaped frame 32.

[0048] The specific working principle of this application is as follows:

[0049] First, engage and fix the mesh cylinder 4 with the pre-set clamping strip 8. Start the motor 75. The motor 75 drives the gear 71 to rotate through the rotating shaft 76. The gear 71 meshes with the rack 72, driving the support sliding plate 73 to move in a straight line, and then driving the U-shaped frame 32 to move along the direction of the baffle plate 31 in the chute. At the first position, finally achieve an embedded connection with the baffle plate 31 to ensure the impact resistance during the packing process. After the equipment is ready, put the forage to be packed into the storage cavity 33 surrounded by the forming box 3 and the mesh cylinder 4. Next, operate the jack 5 to move downward in the vertical direction, so that the pressing plate 6 can strongly compress the forage in the storage cavity 33 in the vertical direction, and compress the forage into a compact bale. During this process, the operator needs to continuously operate the jack 5 to rise and fall in order to gradually fill the forage into the storage cavity 33. After adding a certain amount of forage, perform a strong compression through the downward pressing action of the jack 5, making the forage compact, reducing the volume, and improving the storage and transportation efficiency. In this continuous process, the key is to ensure that after each compaction, the newly added forage can be tightly combined with the already compacted part to form a highly dense bale until the stacking height of the forage in the storage reaches the position flush with the top of the mesh cylinder 4, which means that the forage has been fully filled and sufficiently compressed. When the forage is fully compressed and baled, make the jack 5 return to the initial position in the vertical direction. Start the motor 75 to reverse. The motor 75 drives the rotating shaft 76 to rotate. The rotating shaft 76 drives the rack 72 and the support sliding plate 73 to move in a straight line together through the gear 71, and then drives the U-shaped frame 32 to move in the direction away from the baffle plate 31. At the second position, separate the U-shaped frame 32 from the baffle plate 31. At this time, the bale is no longer blocked by the U-shaped frame 32, and the operator can move the packed bale and the mesh cylinder 4 wrapped inside it along the direction of the free end of the clamping strip 8 out of the base 1, complete the entire packing process, and perform the next baling operation.

[0050] The above-described embodiments only illustrate the equipment layout of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several adjustments and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
