Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, specifically relating to a feeding device and a round bale baler using the feeding device. Background Technology

[0002] A round baler is a machine used for baling straw in agriculture. It connects to a tractor via a tow frame, and its power comes from the tractor's rear output power connected to a gearbox, which then drives the forming rollers. Currently, the main applications of round balers are for baling and removing straw from fields, including livestock, wheat, rice, and corn. Pick-up balers are used for hay, wheat straw, and rice straw, while crushing balers are used for corn, sunflower, and other straws. Pick-up balers have a pick-up mechanism with a pick-up feed, while crushing balers have a crushing pick-up mechanism with a crushing feed.

[0003] Existing pickup-type balers all use a one-sided drive system for their feeding devices. This means the moving blade drives the left auger via a chain, the left auger drives the pickup mechanism via a pickup chain, and the right side of the pickup mechanism drives the right auger via another chain. Therefore, if any part of the chain fails, the right auger will be unable to feed material properly.

[0004] The existing picking mechanism of the crushing baler cannot provide a reversing device for the right auger. A reversing mechanism and a device to provide power to the right auger need to be added to the feeding device. Therefore, the same feeding device cannot be matched with both the picking mechanism and the crushing picking mechanism at the same time. Utility Model Content

[0005] The purpose of this application is to provide a feeding device designed to match different types of picking mechanisms and reduce the failure rate of the right-side auger.

[0006] To achieve the above objectives, this application provides a feeding device, which includes: Feed rack; The moving blade assembly is driven by a gearbox and rotatably mounted on the feed frame; The left auger assembly is rotatably mounted on the feed frame and is used to convey materials to the moving blade assembly; The right auger assembly is rotatably mounted on the feed frame and is used to convey materials to the moving blade assembly; The left drive assembly is driven to connect the left end of the moving blade assembly and the left auger assembly; The right drive assembly is driven and connected between the right end of the moving blade assembly and the right auger assembly.

[0007] In some embodiments, the left drive assembly includes: The first transmission gear is fixed to the left end of the moving blade assembly; The second transmission gear meshes with the first transmission gear and enables reversal; The first drive shaft is coaxially connected to the second drive gear; The first chain drive mechanism is connected between the first drive shaft and the left auger assembly.

[0008] In some embodiments, the first chain drive mechanism includes: The first sprocket is fixed to the first drive shaft; The second sprocket is fixed to the left auger assembly; The first chain is fitted onto the first sprocket and the second sprocket and engages for transmission.

[0009] In some embodiments, the second sprocket is a double-row sprocket and includes sprocket A and sprocket B arranged in parallel, wherein sprocket A is used to drive the left auger assembly and sprocket B is used to drive the pickup-type pickup mechanism.

[0010] In some embodiments, the left drive assembly further includes a clutch mounted on the first drive shaft, and the first sprocket is mounted on the clutch.

[0011] In some embodiments, the right drive assembly includes: The second drive shaft is coaxially mounted on the right end of the moving blade assembly; The third transmission gear is fixed to the end of the second transmission shaft away from the moving blade assembly; The fourth transmission gear meshes with the third transmission gear and enables reversal; The second chain drive mechanism is connected between the fourth transmission gear and the right auger assembly.

[0012] In some embodiments, the second chain drive mechanism includes: The third sprocket is coaxially connected to the fourth transmission gear; The fourth sprocket is fixed to the right auger assembly; The second chain is fitted onto the third and fourth sprockets and engages with them for transmission.

[0013] In some embodiments, the right drive assembly further includes: The third drive shaft is coaxially connected to the fourth drive gear; The sprocket is fixed to the third drive shaft; The third sprocket is fixed to the sprocket disc by a safety bolt.

[0014] In some embodiments, the second drive shaft and the moving blade assembly are coaxially connected via a sprocket coupling.

[0015] A second aspect of this application provides a round bale baler, which includes the feeding device described above.

[0016] This utility model's technical solution includes a feeding frame, a moving blade assembly, a left auger assembly, a right auger assembly, a left transmission assembly, and a right transmission assembly. The tractor's rear output power is connected to a gearbox, which provides the power source and drives the moving blade assembly to rotate relative to the feeding frame. The two ends of the moving blade assembly drive the left and right auger assemblies to rotate through two transmission assemblies respectively; that is, the left transmission assembly drives the left auger assembly, and the right transmission assembly drives the right auger assembly. The two auger assemblies convey the material to the position of the moving blade assembly to achieve feeding. By using the same power source to drive both auger assemblies and achieve material conveying, this technology effectively solves the technical problems in existing technologies where multiple chains sequentially transmit power, leading to a high failure rate of the right-side auger and the inability of the same type of feeding device to adapt to different picking mechanisms. It also achieves at least the following technical effects: 1. The left drive assembly for driving the left auger assembly and the right drive assembly for driving the right auger assembly are independent of each other. If one drive assembly fails, the other drive assembly can still work normally. 2. The feeding device can be matched with both picking-up and crushing picking mechanisms, improving the product's versatility.

Detailed Implementation

[0020] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] This utility model proposes a feeding device 100.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of this utility model, the feeding device 100 includes a feeding frame 10, a moving blade assembly 20, a left auger assembly 30, a right auger assembly 40, a left transmission assembly 50, and a right transmission assembly 60. The moving blade assembly 20 is driven by a gearbox and rotatably mounted on the feeding frame 10; the left auger assembly 30 is rotatably mounted on the feeding frame 10 and is used to convey material to the moving blade assembly 20; the right auger assembly 40 is rotatably mounted on the feeding frame 10 and is used to convey material to the moving blade assembly 20; the left transmission assembly 50 is driven and connected between the left end of the moving blade assembly 20 and the left auger assembly 30; and the right transmission assembly 60 is driven and connected between the right end of the moving blade assembly 20 and the right auger assembly 40.

[0024] The gearbox transmits power to the moving blade assembly 20 via a double-row chain, causing the moving blade assembly 20 to rotate relative to the feeding frame 10. The moving blade assembly 20 includes a blade bar and several moving blades evenly fixed on the blade bar. The left and right ends of the blade bar drive the left and right augers to rotate simultaneously via transmission components. The direction of the spiral blades of the left auger assembly 30 is opposite to that of the spiral blades of the right auger assembly 40. Specifically, the left auger assembly 30 has a right-hand thread, and the right auger assembly 40 has a left-hand thread. When the moving blade assembly 20 rotates, the left auger assembly 30 pushes the crop to the right, and the right auger assembly 40 pushes the crop to the left. Under the bidirectional push of the spiral blades of the two auger assemblies, the material is gathered to the middle position and uniform feeding is achieved. Both the left transmission component 50 and the right transmission component 60 adopt chain drive, that is, the left transmission component 50 realizes the rotation of the left auger assembly 30 through chain drive, and the right transmission component 60 realizes the rotation of the right auger assembly 40 through chain drive. Although the left auger assembly 30 and the right auger assembly 40 are driven by the same power source, they rotate through different transmission components. Therefore, if one transmission component fails, it will not affect the normal operation of the other auger assembly.

[0025] In existing technologies, since the left auger is driven by a moving blade and the right auger is driven by a pickup mechanism, the feeding device cannot achieve a single power source driving all components during sample break-in. A power source needs to be installed at the moving blade location, and another power source needs to be added to drive the right auger. This complicates the manufacturing process of the break-in table and increases production costs. The technical solution of this invention also solves the problem of high testing costs in existing technologies. Since both the left auger assembly 30 and the right auger assembly 40 are powered by the moving blade assembly 20, the break-in table only needs one power source, reducing the manufacturing difficulty and cost of the break-in table.

[0026] Furthermore, in existing technologies, the crushing baler includes a crushing pickup mechanism and a crushing feeder. The crushing feeder still uses a one-sided drive method, only driving the left auger. Although the crushing pickup mechanism has a power source and does not need to be driven by the crushing feeder, it cannot provide a reversing device for the right auger. Therefore, a reversing mechanism and a power supply device for the right auger need to be added to the crushing feeder. Due to the structural differences between the crushing pickup mechanism and the pickup mechanism, they cannot be adapted to the same feeder. The technical solution of this utility model can also solve the technical problems of low product versatility and high cost caused by the need to design two different feeders due to the different structures of the pickup mechanisms in existing technologies. Specifically, for crushing and picking mechanisms with a power source, the moving blade assembly 20 of the feeding device 100 only needs to drive the left auger assembly 30 and the right auger assembly 40. For picking mechanisms without a power source, the moving blade assembly 20 of the feeding device 100, in addition to driving the left auger assembly 30 and the right auger assembly 40, also connects to the picking chain 70 through the left auger assembly 30 and drives the picking mechanism. Therefore, the feeding device 100 of this invention can be matched with various picking mechanisms, improving the product's versatility. The two-sided transmission assemblies drive the two-sided auger assemblies with more even force, and compared to one-sided transmission, the torque is reduced, which can protect the chain.

[0027] Although using a two-sided drive system can reduce torque, a safety protection mechanism is still needed to prevent chain damage due to excessive torque and chain breakage caused by excessive force. In existing technology, for pick-up balers, the left auger, pick-up mechanism, and right auger are driven sequentially by multiple chains. The clutch is designed to activate only when the torque borne by these three components reaches a set value. If one auger has more material and experiences a larger torque, while the other auger has less material and experiences only a smaller torque, the total torque value will not reach the set value, and the clutch will not activate. This means that even with a safety clutch, chain breakage can still occur. Therefore, to solve the above problem, the embodiments of this application include safety protection devices in both the left drive assembly 50 and the right drive assembly 60.

[0028] like Figure 2 and Figure 4 As shown, the left transmission assembly 50 includes a first transmission gear 51, a second transmission gear 52, a first transmission shaft 53, and a first chain transmission mechanism 54. The first transmission gear 51 is fixed to the left end of the moving blade assembly 20; the second transmission gear 52 meshes with the first transmission gear 51 and reverses direction; the first transmission shaft 53 is coaxially connected with the second transmission gear 52; and the first chain transmission mechanism 54 is driven between the first transmission shaft 53 and the left auger assembly 30.

[0029] Specifically, the feed frame 10 has a first bearing seat 11 on the side facing the left transmission assembly 50. The first transmission gear 51 and the second transmission gear 52 are rotatably mounted on the first bearing seat 11 and meshed together. The left end of the moving blade assembly 20 (specifically the left end of the blade bar) passes through the first bearing seat 11 and is fixedly connected to the first transmission gear 51. The blade bar and the first transmission gear 51 are fixed together by a snap ring. The first transmission shaft 53 is parallel to the blade bar. One end of the first transmission shaft 53 is fixed to the second transmission gear 52 by a threaded fastener, and the other end extends away from the blade bar. The first transmission shaft 53 is parallel to the left auger assembly 30. The first transmission shaft 53 and the left auger assembly 30 are driven by a first chain transmission mechanism 54, so that the left auger assembly 30 and the first transmission shaft 53 rotate in the same direction. The first transmission gear 51 and the second transmission gear 52 mesh together to drive the first transmission shaft 53 to rotate. The direction is reversed by a single-stage gear transmission, so that the rotation direction of the left auger assembly 30 is opposite to that of the moving blade assembly 20.

[0030] Furthermore, such as Figure 2 and Figure 4 As shown, the first chain drive mechanism 54 includes a first sprocket 541, a second sprocket 542, and a first chain 543. The first sprocket 541 is fixed to the first drive shaft 53; the second sprocket 542 is fixed to the left auger assembly 30; and the first chain 543 is sleeved on the first sprocket 541 and the second sprocket 542 and engages for transmission. A safety device on the left drive assembly 50 is a clutch 55, which is installed at the end of the first drive shaft 53 away from the second drive gear 52. The first sprocket 541 is mounted to the clutch 55 by fasteners, which can be bolts or other fastening structures. When the left auger assembly 30 is subjected to a large torque, the clutch 55 disconnects from the first drive shaft 53. At this time, the first sprocket 541 connected to the clutch 55 loses its power source, preventing severe blockage of the left auger assembly 30 from causing the first chain 543 to break due to excessive force.

[0031] like Figure 2As shown, the left drive assembly 50 simultaneously drives the left auger assembly 30 and the pickup-type pickup mechanism via the second sprocket 542 of the left auger assembly 30. Specifically, the second sprocket 542 is a double-row sprocket including sprockets A and B arranged in parallel. Sprocket A drives the left auger assembly 30, and sprocket B drives the pickup-type pickup mechanism. The first chain 543 meshes with sprocket A on the second sprocket 542 to achieve transmission, while the pickup-type pickup mechanism is transmitted to sprocket B via the pickup chain 70. Therefore, when the first sprocket 541 rotates, sprockets A and B on the second sprocket 542 rotate simultaneously through the transmission of the first chain 543, thereby realizing the rotation of the left auger assembly 30 and the driving of the pickup-type pickup mechanism, respectively. It should be noted that sprocket B is only needed when the matched pickup mechanism is a pickup-type pickup mechanism; it is not needed when the matched pickup mechanism is a crushing-type pickup mechanism. When the left drive assembly 50 is connected to the pickup mechanism, the clutch 55 not only protects the first chain 543, but also protects the pickup chain 70.

[0032] like Figure 3 and Figure 5 As shown, the right transmission assembly 60 includes a second transmission shaft 61, a third transmission gear 62, a fourth transmission gear 63, and a second chain transmission mechanism 64. The second transmission shaft 61 is coaxially mounted on the right end of the moving blade assembly 20. The third transmission gear 62 is fixed to the end of the second transmission shaft 61 away from the moving blade assembly 20. The fourth transmission gear 63 meshes with the third transmission gear 62 and reverses direction. The second chain transmission mechanism 64 is driven between the fourth transmission gear 63 and the right auger assembly 40.

[0033] Specifically, the feed frame 10 has a second bearing seat 12 on the side facing the right transmission assembly 60. The third transmission gear 62 and the fourth transmission gear 63 are rotatably mounted on the second bearing seat 12 and meshed. One end of the second transmission shaft 61 is fixedly connected to the right end of the moving blade assembly 20 (specifically the right end of the blade bar), and the other end passes through the second bearing seat 12 and is fixedly connected to the third transmission gear 62. The second transmission shaft 61 and the third transmission gear 62 are fixed together by threaded fasteners. The second transmission shaft 61 is parallel to the right auger assembly 40. The second transmission shaft 61 drives the third transmission gear 62 and the fourth transmission gear 63 to mesh. The reversal is achieved through a single-stage gear transmission. The fourth transmission gear 63 is driven by the right auger assembly 40 through a second chain transmission mechanism 64. Finally, the rotation direction of the right auger assembly 40 and the moving blade assembly 20 are opposite.

[0034] Furthermore, such as Figure 3 and Figure 5As shown, the second chain drive mechanism 64 includes a third sprocket 641, a fourth sprocket 642, and a second chain 643. The third sprocket 641 is coaxially connected to the fourth transmission gear 63. The fourth sprocket 642 is fixed to the right auger assembly 40. The second chain 643 is sleeved on the third sprocket 641 and the fourth sprocket 642 and engages for transmission. Although the right drive assembly 60 only needs to drive the right auger assembly 40, and the risk of chain breakage is relatively low, for safety reasons, the right drive assembly 60 is also equipped with a protective device. The protective device on the right drive assembly 60 includes a safety bolt 67. Specifically, the right drive assembly 60 also includes a third drive shaft 65 and a sprocket disc 66. The third drive shaft 65 is coaxially connected to the fourth transmission gear 63. The sprocket disc 66 is fixed to the third drive shaft 65 by a flat key. The third sprocket 641 is fixed to the sprocket disc 66 by the safety bolt 67. When the right auger assembly 40 is subjected to excessive torque due to extreme working conditions, the safety bolt 67 can break in time, causing the third sprocket 641 to lose its power source, thus preventing the right auger assembly 40 from becoming severely blocked and causing the second chain 643 to break due to excessive force.

[0035] like Figure 3 and Figure 5 As shown, the installation protection device of the right transmission assembly 60 also includes a sprocket coupling 68. Specifically, the second transmission shaft 61 and the tool bar of the moving tool assembly 20 are coaxially connected via the sprocket coupling 68. The second transmission shaft 61 and the sprocket coupling 68 are connected via a flat key, and the tool bar of the moving tool assembly 20 is also connected to the sprocket coupling 68 via a flat key. This second safety protection measure is in place so that in special circumstances, if the safety bolt 67 fails to break in time or becomes jammed after breaking, preventing timely disconnection of the transmission, the double-row chain on the sprocket coupling 68 can break to provide emergency protection for the transmission device.
