These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] As described in the background technology, the baler of the related technology includes a frame and a baling chamber arranged on the frame. The baler continuously picks up the hay on the field and sends it into the baling chamber. The hay is piled in the baling chamber and baled. After baling, the bales are discharged to the field through the baling chamber. The hay is a loose material. The baler can only bale a small amount of hay at a time. When the total amount of hay is the same, the baler needs to bale the hay more times, thereby reducing the baling efficiency of the hay.

[0031] In view of the above technical problems, an embodiment of the present application provides a density adjustment device for a baling system, which drives a driving block to descend through an oil cylinder, and the driving blocks on both sides can simultaneously drive a compression top plate to descend, so that the compression top plate first abuts against the top of the grass. When the compression top plate can no longer continue to descend, because the driving end of the oil cylinder is hingedly arranged on the driving block, and the compression side plate is hingedly arranged on the driving block, the driving block rotates, thereby driving the compression side plate to move toward the direction of the grass. The oil cylinder continues to drive the driving block to descend. Because the cylinder body of the oil cylinder is hingedly arranged on the frame body, the oil cylinder rotates along the hinge on the frame body, so that the oil cylinder continues to drive the driving block to rotate, so that the compression side plate further moves toward the direction of the grass, so that the compression top plate and the compression side plates on both sides move simultaneously to compress the grass, so that the baler can bale more grass at one time, reducing the overall number of bales of grass on the site, thereby improving the baling efficiency of the grass, and improving the density of the grass after baling, improving the overall uniformity of the grass bale, thereby improving the baling effect of the grass.

[0032] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0033] Combination Figure 1 and Figure 2 A density adjustment device for a baling system includes a baling chamber 100, which includes a frame 110, a compression side plate 120, a compression top plate 130 and a driving member 140. Compression side plates 120 are arranged on the frame 110 and on both sides of the frame 110. The compression top plate 130 is located between the compression side plates 120 on both sides. A compression space 160 for compressing forage is provided between the compression top plate 130 and the compression side plates 120 on both sides. The driving member 140 is used to drive the compression top plate 130 and the compression side plates 120 on both sides to compress or release the forage at the same time.

[0034] Combination Figure 1 and Figure 2In this embodiment, the frame 110 includes a base 111, a bottom plate 112 and a plurality of rods 113, the bottom plate 112 is arranged on the base 111, and the plurality of rods 113 are evenly distributed on the bottom plate 112 along the width direction of the bottom plate 112; the baling chamber 100 is used to connect with the discharge end of the baler, so that the baling chamber 100 receives the grass picked up by the baler; the baling mechanism of the baling chamber 100 for baling the compressed grass is arranged at the discharge position of the baling chamber 100, so that the grass compressed by the compression top plate 130 and the compression side plate 120 can be baled.

[0035] By adopting the above technical solution, the setting of the driving member 140 can simultaneously drive the compression top plate 130 and the compression side plates 120 on both sides to move, so that the compression top plate 130 and the compression side plates 120 on both sides can realize simultaneous compression of the top and sides of the grass, thereby improving the density of the grass after compression and forming, and making the grass bale have better uniformity after compression, and by compressing the grass, the baler can bale more grass at one time, thereby improving the baling efficiency of the grass; the setting of the driving member 140 improves the driving effect of the compression top plate 130 and the compression side plates 120 on both sides, thereby improving the compression effect of the grass.

[0036] Combination Figure 1 and Figure 2 The driving member 140 includes two driving components 141, and the two driving components 141 are respectively arranged on both sides of the frame 110. The two driving components 141 are respectively arranged corresponding to the compression side plates 120 on both sides. The driving components 141 are used to drive the compression top plate 130 and the corresponding compression side plates 120 to compress or release the grass at the same time.

[0037] By adopting the above technical solution and setting up two driving components 141, the two driving components 141 can simultaneously drive the top plate to move, and the two driving components 141 can respectively drive the compression side plates 120 on both sides to move. The two driving components 141 are used to simultaneously drive the compression top plate 130 to move, thereby improving the compression effect of the compression top plate 130 on the forage.

[0038] Combination Figure 1 and Figure 2 The driving assembly 141 includes a driving block 142 and a driving part 143. The compression top plate 130 is hinged on the driving blocks 142 on both sides. The compression side plates 120 on both sides are respectively hinged on the driving blocks 142 on both sides. The driving block 142 is hinged on the driving part 143. The driving part 143 is used to drive the driving block 142 to descend or rise, so as to drive the compression top plate 130 and the compression side plates 120 to compress or decompress the grass at the same time.

[0039] By adopting the above technical scheme, the driving block 142 is driven to descend by the driving part 143. Since the compression top plate 130 is hingedly arranged on the driving blocks 142 on both sides, the driving blocks 142 on both sides drive the compression top plate 130 to descend, so that the compression top plate 130 compresses the top of the forage. Since the compression side plates 120 on both sides are respectively hingedly arranged on the driving blocks 142 on both sides, and the driving blocks 142 are hingedly arranged on the driving part 143, the driving blocks 142 are driven to rotate while descending, so that the compression side plates 120 on both sides are respectively located at the hinges of the driving blocks 142 on both sides and rotate, and the driving blocks 142 are located at the hinge points of the driving part 143 and rotate, so that the compression side plates 120 on both sides move toward the forage, so that the compression side plates 120 on both sides move simultaneously to compress the sides of the forage, thereby improving the driving effect of the compression top plate 130 and the compression side plates 120 on both sides.

[0040] Combination Figure 1 and Figure 2 The driving part 143 includes a cylinder, a cylinder body of the cylinder is connected to the frame 110, and a driving end of the cylinder is hinged to the driving block 142.

[0041] By adopting the above technical solution, the drive block 142 is driven to move by the oil cylinder, so that the drive block 142 drives the compression top plate 130 and the compression side plate 120 to move simultaneously. The oil cylinder is set up with a simple structure and easy maintenance, which improves the driving effect of the drive block 142.

[0042] In other embodiments, the driving part 143 can be replaced by an electric cylinder, an air cylinder or a hydraulic cylinder. By connecting the cylinder body of the electric cylinder, the air cylinder or the hydraulic cylinder to the frame 110, the driving end of the electric cylinder, the air cylinder or the hydraulic cylinder is hinged to the driving block 142, so that the electric cylinder, the air cylinder or the hydraulic cylinder can realize the lifting and lowering drive of the driving block 142.

[0043] Combination Figure 1 and Figure 2 The driving block 142 is arranged in a triangular shape as a whole, and the compression top plate 130, the compression side plate 120 and the driving end of the oil cylinder are respectively hingedly arranged on the three vertices of the triangular driving block 142.

[0044] In this embodiment, when the compression top plate 130 and the compression side plates 120 on both sides do not compress the grass, one of the sides of the triangular driving block 142 is set parallel to the side plate of the frame 110. When the compression top plate 130 moves toward the grass, the upper part of this side moves in the direction away from the frame 110, and the lower part of this side moves in the direction close to the frame 110.

[0045] By adopting the above technical solution, by setting the driving block 142 as a whole in a triangular shape, it is convenient to produce the driving block 142, and when the cylinder drives the driving block 142 to rotate, it prevents the triangular driving block 142 from interfering with other components, thereby indirectly improving the driving block 142 to drive the compression top plate 130 and the compression side plate 120 to move.

[0046] Combination Figure 1 and Figure 2 The cylinder body of the oil cylinder is hingedly arranged on the frame body 110 .

[0047] Combination Figure 1 and Figure 2 In this embodiment, a mounting rod 114 is extended from the base 111 toward the position where the oil cylinder is located, and the cylinder body of the oil cylinder is hinged on the mounting rod 114. The cylinder body of the oil cylinder is hinged on the base 111 of the frame 110 through the mounting rod 114; the cylinder body of the oil cylinder rotates in the vertical direction toward or away from the frame 110 at the hinge on the frame 110.

[0048] By adopting the above technical solution, by hingedly setting the cylinder body of the cylinder on the frame 110, when the cylinder drives the driving block 142 to rotate, the cylinder itself can rotate at the hinge of the frame 110, so that the cylinder further drives the driving block 142 to rotate, thereby increasing the rotation range of the driving block 142, thereby further enabling the driving block 142 to drive the compression top plate 130 and the compression side plate 120 to move, increasing the movement range of the compression top plate 130 and the compression side plate 120, thereby improving the compression effect of the compression top plate 130 and the compression side plate 120 on the forage.

[0049] Combination Figure 2 and Figure 3 A hinge shaft 150 is provided at the hinged position of the compression top plate 130, the compression side plate 120, the driving end of the cylinder and the driving block 142, and the hinged position of the cylinder body of the cylinder and the frame body 110. The hinge shaft 150 includes a bolt 151 and a nut 152 sleeved and threadedly connected to the bolt 151.

[0050] Combination Figure 2 and Figure 3In the present embodiment, taking the hinge shaft 150 at the hinge of the compression top plate 130 and the driving block 142 as an example, the rod of the bolt 151 is simultaneously passed through the compression top plate 130 and the driving block 142, the nut 152 is sleeved and threadedly connected to the rod of the bolt 151, the compression top plate 130 and the driving block 142 can be rotated on the rod of the bolt 151, so that the compression top plate 130 and the driving block 142 are hinged together by the bolt 151 and the nut 152; the installation and use principles of the hinge shafts 150 at other positions are consistent with the hinge shafts 150 of the compression top plate 130 and the driving block 142 mentioned above, and will not be repeated here one by one.

[0051] By adopting the above technical solution, by setting the articulated shaft 150 at each articulated joint as a combination of a bolt 151 and a nut 152, and by unscrewing the nut 152 along the bolt 151, the articulated shaft 150 can be removed at each articulated joint, which makes it easy to remove the oil cylinder for maintenance and replacement, and to maintain the articulated shaft 150, thereby improving the articulated rotation effect of each articulated joint; the setting of the bolt 151 and the nut 152 improves the strength of the articulated shaft 150, and the installation and disassembly methods of the articulated shaft 150 are relatively convenient and simple.

[0052] Combination Figure 1 and Figure 2 The compression top plate 130 includes a connecting column 131 and a plurality of compression top rods 132 . The plurality of compression top rods 132 are evenly distributed along the length direction of the connecting column 131 . The plurality of compression top rods 132 are arranged on the surface of the connecting column 131 facing the frame body 110 .

[0053] Combination Figure 1 and Figure 3 In this embodiment, the connecting column 131 is arranged along the width direction of the base 111; hinge plates 133 are extended on the two surfaces of the connecting column 131 that are opposite to the driving block 142, and the rod portion of the bolt 151 is simultaneously penetrated through the driving block 142 and the hinge plates 133 on both sides, and the head of the bolt 151 and the nut 152 are respectively used to abut against the two surfaces of the hinge blocks on both sides; when the driving block 142 moves, the driving block 142 can drive the connecting column 131 to move through the hinge plates 133, so that the connecting column 131 drives the multiple compression push rods 132 to move.

[0054] By adopting the above technical solution, the connecting column 131 is driven to move by the driving member 140, so that the connecting column 131 drives the multiple compression top rods 132 to move toward the grass, so that the multiple compression top rods 132 can compress the top of the grass. By adopting the setting of the connecting column 131 and the multiple compression top rods 132, the simultaneous movement of the multiple compression top rods 132 can be achieved by driving the connecting column 131 to move. The setting of the multiple compression top rods 132 increases the contact area with the grass, so that the grass of different lengths has a better compression effect.

[0055] Combination Figure 1 and Figure 2 The compression side plate 120 includes a plate body 121 and a plurality of side rods 122. The plurality of side rods 122 are evenly arranged on the plate body 121 along the height direction of the plate body 121. The side rods 122 are arranged on the opposite surfaces of the plate bodies 121 on both sides. The driving member 140 is used to drive the plurality of side rods 122 to drive the plate body 121 to move.

[0056] Combination Figure 1 and Figure 2 In this embodiment, the plate body 121 is arranged along the length direction of the compression locking push rod, the side rod 122 is arranged along the length direction of the compression push rod 132, and the side rod 122 is arranged parallel to the compression push rod 132.

[0057] By adopting the above technical solution, the plate body 121 and multiple side rods 122 are arranged, and the plate body 121 can prevent the grass from falling out along the gap between adjacent side rods 122, and the arrangement of the plate body 121 improves the contact effect between the plate body 121 and the grass, thereby improving the compression effect on the grass.

[0058] Combination Figure 1 and Figure 2 The compression side plate 120 also includes a driving plate 123 , on which a plurality of grooves 124 are formed, and the side rods 122 are connected to the grooves 124 one by one, and the driving member 140 is used to drive the driving plate 123 to drive the plate body 121 to move.

[0059] Combination Figures 1 to 3 In this embodiment, the driving plate 123 is arranged along the height direction of the plate body 121, and the length direction of the driving plate 123 is arranged perpendicular to the length direction of the side rod 122; a rotating plate 125 is fixedly arranged on the driving plate 123 and is embedded and rotatably connected to the driving block 142. The rod portion of the bolt 151 is simultaneously penetrated through the driving block 142 and the rotating plate 125. The head of the bolt 151 and the nut 152 are respectively used to abut against two surfaces opposite to each other of the driving block 142. When the driving block 142 moves, it can drive the hinge point of the driving plate 123 located on the driving block 142 to rotate, so that the driving plate 123 drives the multiple side rods 122 to move, and the multiple side rods 122 drive the plate body 121 to move.

[0060] By adopting the above technical solution, the setting of the driving plate 123 makes it easy for the driving member 140 to drive the multiple side rods 122 to move through the driving plate 123, thereby making it easy for the multiple side rods 122 to drive the plate body 121 to move; by moving the side rods 122 into the grooves 124 and driving the side rods 122 to be fixed in the grooves 124, the side rods 122 and the driving plate 123 are prevented from being separated, thereby improving the fixing effect between the side rods 122 and the driving plate 123, and separating the multiple side rods 122 through the grooves 124, so that the multiple side rods 122 are evenly distributed on the plate body 121, thereby improving the compression effect of the multiple side rods 122 on the plate body 121 on the forage.

[0061] The oil cylinder drives the driving block 142 to descend, and the driving blocks 142 on both sides can simultaneously drive the compression top plate 130 to descend, so that the compression top plate 130 first abuts against the top of the grass. When the compression top plate 130 can no longer continue to descend, the driving end of the oil cylinder is hingedly set on the driving block 142, and the compression side plate 120 is hingedly set on the driving block 142, so that the driving block 142 rotates, thereby driving the compression side plate 120 to move toward the direction of the grass. The oil cylinder continues to drive the driving block 142 to descend. Because the cylinder body of the oil cylinder is hingedly set on the frame body 110 On the frame 110, the oil cylinder rotates along the hinge on the frame 110, so that the oil cylinder continues to drive the driving block 142 to rotate, so that the compression side plate 120 moves further toward the direction of the hay, and the compression top plate 130 and the compression side plates 120 on both sides move simultaneously to compress the hay, so that the baler can bale more hay at one time, reducing the overall number of bales of hay on the site, thereby improving the baling efficiency of the hay, and increasing the density of the hay after baling, improving the overall uniformity of the hay bale, thereby improving the baling effect of the hay.
