[0056] Please refer to Figure 4, the braking assembly 62 includes a brake disc 621 fixed to the fixed tightening assembly 611 and rotating synchronously with the net bundle, and a clamping assembly 622 for clamping the brake disc 621 and providing braking force for the brake disc 621; the clamping here means providing appropriate frictional force for the brake disc 621, so that the net bundle can maintain a set tension when releasing the net.

[0057] By respectively abutting the two ends of the net bundle through the relatively arranged fixed tightening assembly 611 and the moving tightening assembly 612, and through the axially elastically telescopic arrangement of the moving tightening assembly 612, the installation and fixation of the net bundle can be facilitated; and through the brake disc 621 arranged on the fixed tightening assembly 611 and rotating synchronously with the net bundle, braking force is provided under the clamping of the clamping assembly 622. Compared with the prior art, the provision of this braking force has nothing to do with the size and dimensions of the net bundle, so a more uniform braking force can be provided, ensuring that the net bundle is always in a tensioned state when releasing the net. The structure is simple, convenient, stable and reliable, which is beneficial to subsequent operations such as the conveying, bundling and cutting of the rope net.

[0058] Optionally, as Figure 5 shown in, in some embodiments of the present invention, the fixed tightening assembly 611 includes a first flange seat 6111, a first rotating shaft 6112 and a first top disc 6113, where: the first flange seat 6111 is fixed to the front bin bracket 21, the first rotating shaft 6112 is rotatably connected to the first flange seat 6111, and both ends protrude from the first flange seat 6111; the first top disc 6113 is coaxially fixed to one end of the first rotating shaft 6112 and faces the moving tightening assembly 612, and the brake disc 621 is coaxially fixed to the other end of the first rotating shaft 6112. Through such an arrangement, the first top disc 6113 and the brake disc 621 can be made to rotate synchronously with the first rotating shaft 6112. When specifically connecting, the connection between the first rotating shaft 6112 and the first top disc 6113 and the brake disc 621 can be realized in the form of a keyway.

[0059] Optionally, as Figure 6 shown in, the first top disc 6113 includes a retaining disc 61131 with a diameter larger than the inner diameter of the net bundle and a top sleeve 61132 coaxially connected to the retaining disc 61131 and used for being inserted into the inner diameter of the net bundle. A chamfered surface 61133 is provided at the end of the top sleeve 61132. When specifically installing, as Figure 4 shown in, the retaining disc 61131 is attached to the end face of the net bundle, the top sleeve 61132 is inserted into the inner diameter of the net bundle. In the embodiment, through the setting of the chamfered surface 61133, it provides a guide for the net bundle to be inserted into the top sleeve 61132, which is beneficial to improving the convenience of installing the net bundle.

[0060] Optionally, as Figure 6As shown in the figure, in order to prevent the net bundle from rotating relative to the first top plate 6113 during rotation, the retaining plate 61131 is also provided with locking holes 61134 for fasteners to pass through, which are used for fixedly connecting with the end face of the net bundle. By setting it like this, when the net bundle is sleeved on the first top plate 6113, and then the screw is inserted into the locking hole 61134 to fixedly connect with the process hole on the end face of the net bundle, the synchronism between the brake disc 621 and the rotation of the net bundle can be ensured.

[0061] Optionally, as Figure 7 As shown in the figure, in some embodiments of the present invention, the specific structure of the moving tightening assembly 612 includes: a second flange seat 6121, a sleeve 6122, a push-pull rod 6123, and a second top plate 6125. Specifically: the second flange seat 6121 is fixed on the front bin bracket 21; the sleeve 6122 is fixedly connected to the second flange seat 6121 and extends in a direction away from the fixed tightening assembly 611; the push-pull rod 6123 passes through the second flange seat 6121 and extends into the sleeve 6122. There is a first compression spring 6124 in the sleeve 6122 with one end abutted against the bottom and the other end abutted against the end of the push-pull rod 6123. The push-pull rod 6123 is slidably arranged relative to the sleeve 6122; the second top plate 6125 is rotatably connected to the other end of the push-pull rod 6123. By moving the push-pull rod 6123 in the sleeve 6122, the second top plate 6125 can be horizontally translated axially. By the pressing of the first compression spring 6124, the pressing force between the second top plate 6125 and the net bundle can be ensured, and thus the fixing reliability of the net bundle can be ensured.

[0062] Optionally, as Figure 8 As shown in the figure, in this embodiment, the second top plate 6125 internally has a fixing cavity 61251, and a bearing 61252 is fixed in the fixing cavity 61251. The push-pull rod 6123 is fixedly connected to the inner ring of the bearing 61252. Through this structural design, the second top plate 6125 can rotate relative to the push-pull rod 6123. When installing the bearing 61252, it can be fixed in the fixing cavity 61251 through a retaining ring or the like, so that the push-pull rod 6123 will not rotate during movement, improving the reliability of the mechanism in use.

[0063] Optionally, as Figure 9As shown in the figure, the clamping assembly 622 includes: a fixed plate 6221, a movable plate 6222, a screw 6223, a second compression spring 6225 and a friction plate 6226. Specifically: The fixed plate 6221 is fixed to the front bin bracket 21; during specific fixation, it is adapted to the position of the first flange seat 6111 so that the brake disc 621 can extend between the fixed plate 6221 and the movable plate 6222; the movable plate 6222 is arranged opposite and parallel to the fixed plate 6221; one end of the screw 6223 is fixedly connected to the movable plate 6222, and the other end passes through the fixed plate 6221 and is screwed with a nut 6224; the second compression spring 6225 is sleeved on the screw 6223 and one end abuts against the fixed plate 6221 and the other end abuts against the nut 6224; thus, by adjusting the position of the nut 6224 on the screw 6223, the clamping force on the brake disc 621 can be adjusted by means of the second compression spring 6225; the friction plate 6226 is connected to the opposite surfaces of the fixed plate 6221 and the movable plate 6222 and is used to contact the brake disc 621.

[0064] Optionally, as Figure 9 As shown in the figure, since the friction plate 6226 needs to be replaced after long-term friction, in order to facilitate the replacement of the friction plate 6226, in this embodiment, the friction plate is detachably connected to the fixed plate, and the friction plate is detachably connected to the movable plate. Here, the detachable connection can be detachably fixed in the form of a fastener.

[0065] Optionally, as Figure 9 As shown in the figure, on the side of the movable plate 6222 away from the friction plate 6226, there is also a limiting bent portion 62221 bent towards the fixed plate 6221. The bent portion is configured such that when the bent portion contacts the fixed plate 6221, the thickness of the two friction plates 6226 has reached the limit of use. By providing the limiting bent portion, damage to the brake disc 621 can be avoided.

[0066] Application scenario of an exemplary embodiment of the mesh braking structure 6:

[0067] In this embodiment, the net bundle is wound into a cylindrical shape by a rope net. As Figures 4 to 9As shown in the figure, before installing the net bundle, first move the second top plate 6125 to the rightmost end. After manually inserting one end of the net bundle into the top sleeve 61132 of the first top plate 6113, then move the second top plate 6125 to the left so that the right end of the net bundle is inserted into the second top plate 6125. Under the action of the first compression spring 6124, it remains pressed against the net bundle, and the installation of the net bundle is completed. Then, adjust the distance between the fixed plate 6221 and the movable plate 6222 in the clamping assembly 622 so that the brake disc 621 is clamped between the two friction plates 6226. By adjusting the position of the adjusting nut 6224 on the screw rod 6223, adjust the pressure of the second compression spring 6225 on the movable plate 6222, so that the frictional force of the two friction plates 6226 on the brake disc 621 keeps the rope net in a tensioned state at all times when the net bundle is releasing the net. The rope net in the tensioned state is beneficial to subsequent conveying, bundling, and cutting the net with a cutting knife. The net laying braking structure 6 of this structure is simple, convenient to install, and can solve the problems of fixing the net bundle and tensioning the net when releasing the net in the bundling machine.

[0068] Optionally, as Figures 10 to 12 shown, the net winding assembly includes a cutting knife return structure 8. The cutting knife return structure 8 is located at one end of the front bin bracket 21 away from the traction frame and can cut the rope net arranged on the net laying braking structure 6. The cutting knife return structure 8 is a split-type cutting knife return structure. The cutting knife return structure 8 includes a cutting knife support 81, a push rod 82, and a push rod spacer sleeve 83. Among them, as Figure 10 shown in

[0069] The cutting knife support 81 is fixedly connected to the front bin bracket 21 of the front bin assembly 2. The cutting knife support 81 has a moving shaft 811 that can reciprocate on the cutting knife support 81. A cutting knife 8112 is arranged on the moving shaft 811 for cutting the rope net; a hook 8111 is also hinged on the moving shaft 811. The cutting knife support 81 also has a limit shaft 8113 for fixing and unhooking the hook 8111. In the embodiment of the present invention, as Figure 10 shown in Figure 10 shown, the cutting edge of the cutting knife 8112 faces left and downward. During the process of the moving shaft 811 moving from top to bottom, the cutting knife 8112 cuts off the rope net; regarding the limit shaft 8113, it can show the fixing and unhooking of the hook 8111 by rotating, that is, as

[0070] One end of the push rod 82 is rotatably connected to the cutting knife 8112, and the other end is arranged towards the rear bin; in the embodiment of the present invention, the movement of the push rod 82 driving the cutting knife 8112 is as follows Figure 10 As shown in, the limiting shaft 8113 rotates counterclockwise so that the hook 8111 is disengaged from the limiting shaft 8113, and the cutting knife 8112 falls by its own gravity to cut the rope net, and at the same time drives the push rod 82 to move towards the left. When the push rod 82 moves towards the right, it pushes the hook 8111 back to its position. The push rod spacer 83 is fixedly connected to the rear bin bracket 31 of the rear bin assembly 3 and rotates with the rear bin assembly 3; as Figure 10 The dotted line shown in is the schematic of the movement track of the push rod spacer 83 fixed on the rotating seat of the rear bin assembly 3, Figure 10 The double-dot dash line shown in represents the future movement position of the push rod 82; specifically, the movement track of the push rod spacer 83 faces the end of the push rod 82 away from the cutting knife 8112, and the push rod spacer 83 is configured to be separated from the push rod 82 at the initial position, and the push rod spacer 83 contacts and pushes the cutting knife 8112 back to its position during the opening process of the rear bin space. That is, on the rotating seat of the rear bin assembly 3, before the rear bin space is opened, the push rod spacer 83 is separated from the push rod 82. When the rear bin space is opened clockwise, the push rod spacer 83 gradually approaches the push rod 82 until it contacts the push rod 82, and then pushes the push rod 82 to move towards the right, so that the push rod 82 pushes the cutting knife 8112 back to its position.

[0071] In the above embodiment, through the separable structure design of the push rod spacer 83 and the push rod 82, the cutting knife 8112 and the push rod 82 can follow the opening and closing of the front bin assembly 2, and after the front bin space is closed, the contact and pushing of the spacer and the push rod 82 are realized through the opening of the rear bin space, so that the cutting knife 8112 can be retracted by means of the opening of the rear bin space after the cutting is completed, thus solving the problem of the cutting knife retraction in the prior art where the front and rear bin assemblies rotate independently but still use the push rod 82 type retraction method.

[0072] Optionally, as Figure 11 shown in, the net cutting bracket 81 has a movement track 812 for the moving shaft 811. The moving shaft 811 is slidably arranged relative to the movement track 812 and cuts the net rope during the sliding process. Of course, it should be noted here that the movement track 812 has various forms, for example, it can be realized by setting a slide rail or the like. In some embodiments of the present invention, as Figure 11 shown in, the movement track 812 is an arc-shaped hole, and one end of the moving shaft 811 is movably connected in the arc-shaped hole. The cutting knife 8112 slides in the arc-shaped hole, and the specific sliding form can adopt the form of a rotating shaft or other structural forms.

[0073] Optionally, as Figure 11 andFigure 13 As shown, in order to avoid excessive swinging of the push rod 82, in an embodiment of the present utility model, the push rod 82 is further provided with a limit elongated hole 821 disposed obliquely, and the frame is further provided with a guiding spacer 84 passing through the limit elongated hole 821. Specifically, the limit elongated hole 821 is configured such that when the moving shaft 811 returns to its position, the guiding spacer 84 is at one end of the limit elongated hole 821, and when the moving shaft 811 is at the other end of the movement track 812, the guiding spacer 84 is at the other end of the limit elongated hole 821. As Figure 10 shown, at this time, the cutting knife 8112 drops, and the guiding spacer 84 is at the rightmost end of the limit elongated hole 821, as Figure 11 shown. When the cutting knife returns to its position, the guiding spacer 84 is at the leftmost end of the limit elongated hole 821; through the setting of this structural form, not only is support provided for the push rod 82 to prevent excessive swinging of the push rod 82, but also the cutting knife 8112 can be protected.

[0074] Optionally, as Figure 14 shown, regarding the specific structure of the push rod 82, one end of the push rod 82 away from the cutting knife 8112 has a pushing portion 822, and the pushing portion 822 is used to contact the push rod spacer 83. Specifically, the pushing portion 822 is in a fish-tail shape and has a notch formed by the intersection of two inclined side walls, and the notch is provided with a rounded corner at the intersection of the two inclined side walls. Through the setting of the fish-tail shape structure, the push rod spacer 83 can be guided, so that the push rod spacer 83 can just contact and apply force at the notch during the movement process; through the setting of the rounded corner, stress concentration can be avoided, and the reliability of pushing the push rod 82 can be improved.

[0075] Optionally, as Figure 11 and Figure 15 shown, the push rod spacer 83 is detachably fixed on the rear bin bracket 31 of the rear bin assembly 3 and can be rotatably arranged relative to the rotating seat of the rear bin assembly 3. Specifically, the push rod spacer 83 includes a cylindrical section 831 close to the rotating seat of the rear bin assembly 3 and a conical section 832 away from the rotating seat of the rear bin assembly 3. The thickness of the cylindrical section 831 matches the thickness of the push rod 82, and the diameter of the conical section 832 increases gradually in the direction away from the cylindrical section 831. Through the setting of this structural form, the conical section 832 can snap the push rod 82 into the fit between the cylindrical section 831 and the rotating seat of the rear bin assembly 3, thereby avoiding the coplanar deviation of the push rod cutting knife and the notch of the push rod 82 caused by the swinging of the push rod 82 and ensuring the reliability of applying force to the push rod 82.

[0076] Application scenario of an exemplary embodiment of the cutting net knife return structure 8:

[0077] As Figures 10 to 15As shown, the hook 8111 is hooked on the limit shaft 8113. During the baling operation, the forage passes through the front bin space and first enters the rear bin space for forming. When the set density is reached, the electromagnetic clutch operates to drive the net winding mechanism for net winding operation. At the same time, the limit shaft 8113 starts to rotate counterclockwise. When the net winding operation is completed, the hook 8111 is unhooked and drops together with the cutting knife 8112 to cut the net. The push rod 82 also moves towards the left side, completing the baling of the bale. The rear bin space is opened to release the bale. During the opening process of the rear bin space, the push rod spacer 83 contacts the notch of the pushing part 822 of the push rod 82. As the rear bin space continues to open, the push rod spacer 83 pushes the push rod 82 to push the cutting knife 8112 to the initial position, realizing the return of the cutting knife 8112, and the hook 8111 is re-hooked on the limit shaft 8113. During the bale discharging process in the rear bin space, the lower bin door assembly closes the passage between the front bin space and the rear bin space, and the forage continuously enters the front bin space for pre-forming. When the bale discharging in the rear bin space is completed and the rear bin space is closed, the lower bin door assembly opens the passage between the front bin space and the rear bin space, and the forage continuously enters the rear bin space. At the same time, the front bin space is opened and the pre-formed forage is transferred to the rear bin space, and the front bin space is closed. At this time, the net cutting bracket 81 also rotates and returns following the opening and closing of the front bin space.

[0078] Application scenario of an exemplary embodiment of a round baler capable of continuous operation:

[0079] As Figures 1 to 16 shown, the round baler capable of continuous operation is connected to a tractor through a towing frame 10. By retracting the telescopic end of the lower bin oil cylinder 43, the lower bin bracket 41 is driven to rotate relative to the main frame body 11 to open the passage between the front bin space and the rear bin space. The length of the feeding inlet of the front bin space is less than the length of the pick-up. The pick-up picks up the forage. Part of the forage passes through the sandwich between the pick-up and the pressing roller and is conveyed by the feeding roller into the front bin space. Another part of the forage is conveyed by the pushing auger to the feeding roller and then conveyed into the front bin space. The forage in the front bin space successively passes through the front bin roller and the lower bin roller and enters the rear bin space through the passage between the front bin space and the rear bin space for baling and forming, that is Figure 16 as shown in

[0080] When the density of the bale in the rear bin space reaches the set density, the net winding assembly winds the bale with multiple layers of nets and then cuts the net. At the same time, by extending the telescopic end of the lower bin oil cylinder 43, the lower bin bracket 41 is driven to rotate relative to the main frame body 11 to close the passage between the front bin space and the rear bin space, that is Figure 16 as shown in

[0081] Forage continuously enters the front bin space and undergoes preprocessing. Meanwhile, the telescopic end of the rear bin oil cylinder 33 extends, the rear bin space opens, and the bales of forage in the rear bin space roll onto the ground through the bale discharge rack 14, as shown in Figure 16 Figure c.

[0082] The front bin space is smaller than the rear bin space. The front bin space is used for preprocessing the forage, and the rear bin space is used for shaping and baling the forage into bales. The telescopic end of the rear bin oil cylinder 33 retracts, the rear bin space closes. At this time, the forage in the front bin space is preprocessed into small bales, as shown in Figure 16 Figure d.

[0083] By retracting the telescopic end of the lower bin oil cylinder 43 and driving the lower bin support 41 to rotate relative to the main frame body 11 to open the channel between the front bin space and the rear bin space. The telescopic end of the front bin oil cylinder 23 extends and drives the front bin support 21 to rotate relative to the main frame body 11. The front bin support 21 rotates and pushes the small bales located in the front bin space into the rear bin space. After that, the telescopic end of the front bin oil cylinder 23 retracts and drives the front bin support 21 to rotate relative to the main frame body 11 to close the front bin space. During the pushing process of the small bales, the small bales pass through the lower bin rollers on the lower bin support and enter the rear bin space. Meanwhile, forage continuously enters the front bin space, and the forage in the front bin space successively passes through the front bin rollers, the lower bin rollers and enters the rear bin space through the channel between the front bin space and the rear bin space for baling and shaping, as shown in Figure 16 Figure e and Figure 16 Figure f.
