Description

Technical Field

[0001] The utility model relates to the technical field of agricultural baling equipment, in particular to a net-laying braking mechanism and a baling machine. Background Art

[0002] A round baler is a commonly used agricultural machine used to pack crops such as grass and straw into round bales for easy storage and transportation.

[0003] The net brake mechanism of the round baler is an important part to ensure that the baled product is tight and easy to operate. Figure 1 As shown in the figure, the existing net-laying braking mechanism mainly includes a support arm b01, a pressure plate b02 rotatably connected to the top of the support arm b01, and a gas spring b03 with one end rotatably connected to the bottom of the support arm b01 and the other end rotatably connected to the top of the pressure plate b02. The net bundle is clamped between the inner walls of the support arm b01 and the pressure plate b02 under the action of the gas spring b03, and the net bundle is rotatably arranged. Through the action of the gas spring b03 on the pressure plate b02, the net-laying speed of the net bundle can be controlled, thereby achieving the effect of tightening the net bundle during the net-winding process.

[0004] However, as the net bundle is continuously released, the diameter and mass of the net bundle become smaller, and the pressure of the pressure plate b02 also decreases, which will eventually lead to insufficient pressure of the pressure plate, causing the tension of the net bundle to decrease during the release process, and even causing the net bundle to jump, with the risk of overlapping or entanglement. At the same time, this device is only suitable for fixed plane installation, and cannot be used for moving or rotating planes. Utility Model Content

[0035] like Figures 2 to 7 As shown, the utility model discloses a net-laying brake mechanism, including a net-bundle fixing component b1 and a brake component b2, as shown in FIG. Figure 2 As shown in , the net bundle fixing assembly b1 includes a fixed top tightening assembly b11 and a dynamic top tightening assembly b12 which are arranged relatively, and the fixed top tightening assembly b11 and the dynamic top tightening assembly b12 are used to clamp and fix the net bundle between the two, and the net bundle follows the two to make free rotation movement; in the embodiment of the utility model, the dynamic top tightening assembly b12 is elastically and retractably arranged along the axial direction. It should be pointed out here that the elastically retractable structure has various forms, such as using a cylinder to drive the axial movement of the dynamic top tightening assembly b12, or using a gas spring, or using a spring, etc., and the axially retractable arrangement can facilitate the installation and disassembly of the net bundle, and when installing or disassembling, the axial retractable dynamic top tightening assembly b12 can be used.

[0036] Please refer to Figure 2 The brake assembly b2 includes a brake disc b21 fixed to the fixed tightening assembly b11 and rotating synchronously with the net bundle, and a clamping assembly b22 for clamping the brake disc b21 and providing braking force for the brake disc b21; clamping here means providing appropriate friction force for the brake disc b21, so that the net bundle can maintain the set tension when releasing the net.

[0037] By relatively arranged fixed clamping components b11 and moving clamping components b12 respectively abutting against both ends of the net bundle, and by the axially elastically telescopic arrangement of the moving clamping components b12, the installation and fixation of the net bundle can be facilitated; and by the brake disc b21 arranged on the fixed clamping components b11 and rotating synchronously with the net bundle, braking force is provided under the clamping of the clamping components b22. 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 to ensure that the net bundle is always in a tensioned state during net release. The structure is simple, convenient, stable and reliable, which is beneficial to subsequent operations such as net rope conveying, bundling and net cutting by the cutting knife.

[0038] Optionally, as Figure 3 shown in, in some embodiments of the present invention, the fixed clamping components b11 include a first flange seat b111, a first rotating shaft b112 and a first top disc b113, wherein: the first flange seat b111 is fixed to the frame, the first rotating shaft b112 is rotatably connected to the first flange seat b111, and both ends protrude from the first flange seat b111; the first top disc b113 is coaxially fixed to one end of the first rotating shaft b112 and faces the moving clamping components b12, and the brake disc b21 is coaxially fixed to the other end of the first rotating shaft b112. Through such an arrangement, it can be ensured that the first top disc b113 and the brake disc b21 rotate synchronously with the first rotating shaft b112. When specifically connecting, the connection between the first rotating shaft b112 and the first top disc b113 as well as the brake disc b21 can be realized in the form of a keyway.

[0039] Optionally, as Figure 4 shown in, the first top disc b113 includes a retaining disc b1131 with a diameter larger than the inner diameter of the net bundle and a top sleeve b1132 coaxially connected to the retaining disc b1131 and used for being inserted into the inner diameter of the net bundle. A chamfered surface b1133 is provided at the end of the top sleeve b1132. When specifically installing, as Figure 2 shown in, the retaining disc b1131 is in contact with the end face of the net bundle, and the top sleeve b1132 is inserted into the inner diameter of the net bundle. In the embodiments of the present invention, through the setting of the chamfered surface b1133, it provides a guide for the net bundle to be inserted into the top sleeve b1132, which is beneficial to improving the convenience of net bundle installation.

[0040] Optionally, as Figure 4 shown in, in order to prevent the net bundle from rotating relative to the first top disc b113 during rotation, the retaining disc b1131 also has locking holes b1134 for fasteners to pass through, which are used for fixedly connecting with the end face of the net bundle. Through such an arrangement, when the net bundle is sleeved on the first top disc b113, and then the screw is inserted into the locking hole b1134 to be fixedly connected with the process hole on the end face of the net bundle, the synchronism of the rotation of the brake disc b21 and the net bundle can be ensured.

[0041] Optionally, as shown in Figure 5 In some embodiments of the present utility model, the specific structure of the moving pressing component b12 includes: a second flange seat b121, a sleeve b122, a push rod b123, and a second top plate b125. Specifically: the second flange seat b121 is fixed to the frame; the sleeve b122 is fixedly connected to the second flange seat b121 and extends in a direction away from the fixed pressing component b11; the push rod b123 passes through the second flange seat b121 and extends into the sleeve b122. A first compression spring b124 is provided in the sleeve b122 with one end abutting against the bottom and the other end abutting against the end of the push rod b123. The push rod b123 is slidably disposed relative to the sleeve b122; the second top plate b125 is rotatably connected to the other end of the push rod b123. By moving the push rod b123 in the sleeve b122, the second top plate b125 can be horizontally translated in the axial direction. By the pressing of the first compression spring b124, the pressing force of the second top plate b125 against the net bundle can be ensured, thereby ensuring the fixing reliability of the net bundle.

[0042] Optionally, as shown in Figure 6 In the embodiments of the present utility model, the second top plate b125 has a fixing cavity b1251 inside. A bearing b1252 is fixed in the fixing cavity b1251. The push rod b123 is fixedly connected to the inner ring of the bearing b1252. Through this structural design, the second top plate b125 can rotate relative to the push rod b123. When installing the bearing b1252, it can be fixed in the fixing cavity b1251 by a retaining ring or the like, so that the push rod b123 will not rotate during movement, improving the reliability of the mechanism in use.

[0043] Optionally, as shown in Figure 7 The clamping component b22 includes: a fixing plate b221, a movable plate b222, a screw rod b223, a second compression spring b225, and a friction plate b226. Specifically: the fixing plate b221 is fixed to the frame; when specifically fixed, it is adapted to the position of the first flange seat b111 so that the brake disc b21 can extend between the fixing plate b221 and the movable plate b222; the movable plate b222 is disposed opposite and parallel to the fixing plate b221; one end of the screw rod b223 is fixedly connected to the movable plate b222, and the other end passes through the fixing plate b221 and is screwed with a nut b224; the second compression spring b225 is sleeved on the screw rod b223 and has one end abutting against the fixing plate b221 and the other end abutting against the nut b224; thus, by adjusting the position of the nut b224 on the screw rod b223, the clamping force on the brake disc b21 can be adjusted by means of the second compression spring b225; the friction plate b226 is connected to the opposite surfaces of the fixing plate b221 and the movable plate b222 and is used to contact the brake disc b21.

[0044] Optionally, as shown in Figure 7As shown, since the friction plate b226 needs to be replaced after long-term friction, in order to facilitate the replacement of the friction plate b226, in the embodiment of the present utility model, the friction plate is detachably connected to the fixed plate, and the friction plate is detachably connected to the movable plate. The detachable connection here can be detachably fixed in the form of fasteners.

[0045] Optionally, as Figure 7 shown, on the side of the movable plate b222 away from the friction plate b226, there is also a limiting bent portion b2221 bent towards the fixed plate b221. The bent portion is configured such that when the bent portion contacts the fixed plate b221, the thickness of the two friction plates b226 has reached the limit of use. By providing the limiting bent portion, damage to the brake disc b21 can be avoided.

[0046] The present utility model also provides a baling machine, including the net laying braking mechanism of any one of the above.

[0047] An application scenario of an exemplary embodiment:

[0048] As Figures 2 to 7 shown, before installing the net bale, first move the second top plate b125 to the rightmost end. After manually inserting one end of the net bale into the top sleeve b1132 of the first top plate b113, then move the second top plate b125 to the left so that the right end of the net bale is stuffed into the second top plate b125, and keep pressing the net bale under the action of the first compression spring b124. The net bale installation is completed. Then adjust the distance between the fixed plate b221 and the movable plate b222 in the clamping assembly b22 so that the brake disc b21 is clamped between the two friction plates b226. By adjusting the position of the adjusting nut b224 on the screw b223, the pressure of the second compression spring b225 on the movable plate b222 is adjusted, so that the frictional force of the two friction plates b226 on the brake disc b21 keeps the net rope in a tensioned state at all times when the net is released. The net rope in the tensioned state is beneficial for subsequent conveying, baling and cutting the net by the cutter. The net laying braking mechanism of this structure is simple in structure, convenient to install, and can solve the problems of fixing the net bale and releasing and stretching the net of the baling machine.
