Description

Technical Field

[0001] The invention belongs to the technical field of straw bale collection, and in particular relates to an automatic straw bale turning and stacking device for a self-propelled straw baler, which automatically transports, collects and stacks baled straw square bales, serving as a link for straw collection, storage and transportation. Background Art

[0002] In the prior art, the straw bale collection of the self-propelled straw baler is usually carried out in two ways: manual collection and mechanical collection.

[0003] Manual collection usually involves loading a trailer and going down to the field for the second time, picking up the bales manually and loading them onto the truck for transportation. Alternatively, the extra space on the chassis of a self-propelled baling device is used as a temporary storage platform for bales, and the bales coming out of the outlet are manually stacked onto the platform. Generally, these two manual collection methods are time-consuming, labor-intensive, and have high operating costs.

[0004] Mechanical collection usually involves mechanical equipment picking up the bales after they fall to the ground, loading them onto trucks for transportation, and other issues such as excessive soil compaction and high equipment costs.

[0005] At present, there is relatively little research on the automated temporary storage device for bales on self-propelled baling equipment. Summary of the invention

[0006] The purpose of the present invention is to solve the defects of the above-mentioned prior art and to provide a device and a method for using the automatic stacking and stacking of square bales of straw, which can realize the automatic collection of straw bales without them falling to the ground, avoid the bales falling to the ground to increase the soil and impurity content, narrow the scope of comprehensive utilization of straw, and at the same time reduce the number of times that bale picking and transportation equipment go to the ground, thereby improving the efficiency of straw collection and reducing the intensity of manual labor.

[0007] The present invention adopts the following technical solution:

[0008] A device for automatically turning and stacking square bales of straw comprises a bale conveying mechanism 1, a hydraulic erecting mechanism 2, and a bale stacking temporary storage mechanism 3. The left side of an erecting plate 22 of the hydraulic erecting mechanism is connected to a transition plate 146 arranged on the side of the tail of the bale conveying mechanism. A bale turning device 14 for turning the bale 90° is installed between the bale conveying plate 13 and the transition plate 146 of the bale conveying mechanism 1. The front end of the hydraulic erecting mechanism 2 is connected to a temporary storage platform of the bale stacking temporary storage mechanism 3. The erecting plate 22 of the hydraulic erecting mechanism stands the bale upright, and the bale baffle 32 of the bale stacking temporary storage mechanism blocks the bale to prevent it from tipping over.

[0009] The bale conveying mechanism 1 includes a grass outlet 11, a photoelectric sensor 12, a bale conveying plate 13, and a bale turning device 14. A hydraulically driven bale turning device 14 is arranged in the direction of bale movement perpendicular to the grass outlet 13. The photoelectric sensor 12 is arranged at the end of the bale conveying plate 13, and the photoelectric sensor 12 captures the bale position signal.

[0010] The bale turning device 14 includes a turning support pallet 141, a support frame 142, a turning auxiliary side plate 143, and a driving shaft 145. A groove is arranged on the bale conveying plate 13. The turning support pallet 141 and the turning auxiliary side plate 143 constitute an L-shaped turning plate. The driving shaft 145 is supported by two sets of support frames 142. The driving shaft 145 swings in a circle under the drive of a hydraulic motor. The right side of the bale turning device 14 is connected to a transition plate 146. One end of the turning support pallet 141 and the turning auxiliary side plate 143 are both arranged on the driving shaft 145. During the turning process, in the initial state, the turning support pallet 141 is flush with the groove of the bale conveying plate 13. In the end state, the turning auxiliary side plate 143 corresponds to the through hole 144 of the transition plate 146.

[0011] A further technical solution of the present invention is that the angle of the L-shaped flip plate formed by the flip support bracket 141 and the flip auxiliary side plate 143 is 100°-120°.

[0012] A further technical solution of the present invention is that the angle between the bale conveying plate 13 and the transition plate 146 is 120°-150°.

[0013] The standing plate 22 of the hydraulic standing mechanism 2 is connected to the bale conveying mechanism 1 through the transition plate 146. The hydraulic standing mechanism 2 is driven to flip by the standing cylinder 21. The displacement sensor 23 is arranged at the other end of the standing plate 22 to detect the presence of continuously arranged bales.

[0014] The temporary storage platform 35 is docked with the upright plate 22, and a support frame 31 is provided above the temporary storage platform 35. A left drive chain 33 and a right drive chain 34 are installed on the support frame 31. The drive chains on both sides are connected by a bale baffle 32, and the drive chains are driven by a synchronous hydraulic motor to ensure that the speeds of the two chains are the same.

[0015] The bale baffle 32 includes a baffle body 44 and a sliding block 42. The support frame 31 includes an upper support frame 41. The drive chain is composed of connecting links 43. The baffle body 44 is connected to the upper support frame 41 through two left-right symmetrical sliding blocks 42, and is connected to the drive chains on both sides through two left-right symmetrical connecting links 43. Driven by the drive chains on both sides, the baffle body 44 makes intermittent motion backward at equal intervals.

[0016] A further technical solution of the present invention is that the temporary storage platform 35 and the vertical plate 22 are not in the same horizontal plane, and the angle between them is 5°-10°.

[0017] The method of using the automatic stacking device for straw square bales is as follows:

[0018] The formed square bales are continuously output from the grass outlet 11 through the bale conveying plate 13, enter the detection range of the photoelectric sensor 12, and are detected. After the trigger signal is transmitted to the bale turning device 14, the bale is turned 90 degrees.

[0019] The bale turning device is composed of two sets of turning support plates 141 and turning auxiliary side plates 143 with an angle of 120°-150°. The two are driven by a driving shaft 143 to swing in a circle and are installed on a supporting frame 142.

[0020] In the initial state, the turning support plate 141 is kept flush with the bale conveying plate 13, and the bale position signal is transmitted to the hydraulic motor controller to drive the L-shaped bale turning device to swing in a cycle.

[0021] The straw bales are sent to the transition plate 146, which is inclined at an angle of 5°-10° to the vertical plate 22. Under the action of gravity, the straw bales slide onto the vertical plate 22, and the continuously incoming straw bales squeeze the initial straw bales, so that a certain number of straw bales are stacked on the vertical plate 22. After the position sensor detects, it sends a signal to the vertical cylinder 22 to flip the straw bale.

[0022] The bale baffle 32 blocks the bale and keeps it in an upright position. The bale baffle 32 is driven by the hydraulic motor to retreat, and the bales are continuously accumulated on the temporary storage platform 35. Finally, the bale baffle 32 pushes the bale from one side to the other side. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Terminology explanation:

[0043] As before, the photoelectric sensor 12 and the displacement sensor 23 can both adopt photoelectric proximity switches, as shown in FIG. 11( a ) and FIG. 11( b ). The parameter information of the photoelectric proximity switch is as follows:

[0046]

[0047] Example 1

[0048] like Figure 1 As shown, an automatic stacking and stacking device for square bales of straw of the present invention comprises a bale conveying mechanism 1, a hydraulic upright mechanism 2, and a bale stacking and temporary storage mechanism 3; the left side of the upright plate 22 of the hydraulic upright mechanism 2 is connected to the transition plate 146 on the side of the rear end of the bale conveying mechanism 1, and the front end of the upright plate 22 of the hydraulic upright mechanism 2 is connected to the bale stacking and temporary storage mechanism 3.

[0049] like Figure 2 As shown, the bale conveying mechanism 1 includes a grass outlet 11, a photoelectric sensor 12, a bale conveying plate 13, and a bale turning device 14. When the photoelectric sensor 12 detects the bale delivered from the grass outlet 11 at the bale conveying plate 13, it immediately sends a signal to the hydraulic motor, and the hydraulic motor drives the bale turning device 14.

[0050] like Figure 3 As shown, the bale turning device 14 includes a turning support pallet 141, a support frame 142, a turning auxiliary side plate 143, a through hole 144, a driving shaft 145, and a transition plate 146. A groove is provided on the bale conveying plate 13. One end of the turning support pallet 141 is mounted on the driving shaft 145. The turning auxiliary side plate 143 is also mounted on the driving shaft 145. The turning support pallet 141 and the turning auxiliary side plate 143 together constitute an L-shaped turning plate. The driving shaft 145 is supported by two groups of support frames 142. The L-shaped turning plate swings in a circle under the drive of the driving shaft 145. The right side of the support frame 142 is connected to the transition plate 146. During the movement of the driving shaft 142, the turning support pallet 141 of the L-shaped turning plate is flush with the groove of the bale conveying plate 13, and the turning auxiliary side plate 143 of the L-shaped turning plate corresponds to the through hole 144 of the transition plate 146.

[0051] like Figure 3 As shown, the included angle of the L-shaped flip plate formed by the flip support bracket 141 and the flip auxiliary side plate 143 is 100°-120°.

[0052] like Figure 1 As shown, the angle between the bale conveying plate 13 and the transition plate 146 is 120-150°.

[0053] like Figure 4-5 As shown, the standing plate 22 of the hydraulic standing mechanism 2 is connected to the bale conveying mechanism 1 through the transition plate 146, and is driven to flip by the standing cylinder 21. The displacement sensor 23 is arranged at the other end of the standing plate 22 to detect the status of the continuously arranged bales in place.

[0054] like Figure 6 As shown, the bale stacking and temporary storage mechanism 3 includes a support frame 31, a bale baffle 32, a left drive chain 33, a right drive chain 34, and a temporary storage platform 35. The temporary storage platform 35 is connected to the vertical plate 22. A support frame 31 is arranged above the temporary storage platform 35, and a left drive chain 33 and a right drive chain 34 are installed thereon. The drive chains on both sides are connected by the bale baffle 32, and a hydraulic motor drives the drive chain to ensure that the speeds of the two chains are the same.

[0055] like Figure 7 As shown, the bale baffle 32 includes a sliding block 42 and a baffle body 44, the support frame 31 includes an upper support frame 41, the drive chain is composed of a plurality of connecting links 43, the baffle body 44 is connected to the upper support frame 41 through two left-right symmetrical sliding blocks 42, and is connected to the drive chains on both sides through two left-right symmetrical connecting links 43. Driven by the drive chains on both sides, the baffle body 44 makes intermittent motion backward at equal intervals.

[0056] like Figure 8 As shown, the angle between the temporary storage platform 35 of the straw bale stacking temporary storage mechanism and the standing plate 22 of the hydraulic standing mechanism is 5°-10°.

[0057] The method for using the automatic stacking device for turning and stacking square bales of straw includes:

[0058] Step 1. Place the packed square bale of straw flat on the conveyor belt of the bale conveying mechanism 1. After the square bale of straw is output from the grass outlet 11, it moves to the bale conveying plate 13 of the flip support pallet 141. The photoelectric sensor 12 detects the bale signal and transmits it to the hydraulic motor after processing. The hydraulic motor drives the bale flipping device 14, flips the bale 90 degrees and then sends it to the transition plate 146.

[0059] Step 2. Under the action of gravity, the straw bale slides onto the vertical plate 22. When the set amount of straw bales is piled on the vertical plate 22, the displacement sensor detects it, and after the signal is processed, it is sent to the vertical cylinder 21. The extended hydraulic shaft of the vertical cylinder 21 lifts the vertical plate 22, and the straw bale is turned 90 degrees and sent into the straw bale stacking temporary storage mechanism 3. The straw bale baffle 32 prevents the straw bale from tipping over.

[0060] Step 3. The upright bales enter the temporary storage platform. When the capacity of the storage platform is reached, the hydraulic motor drives the drive chain to drive the bale baffle 32 to transport the bales on the temporary storage platform from one side to the transportation tool on the other side, such as a delivery truck.

[0061] The specific implementation is: Figure 9-10 As shown, the formed bale 51 is squeezed by the subsequent straw bale, and moves forward continuously in direction one on the bale conveying plate 13 with its back to the grass outlet 11. When it moves to the bale with flipping 52 (with a photoelectric sensor installed), it enters the detection range of the photoelectric sensor 12 and triggers a signal. The signal is transmitted to the bale flipping device 14, and the bale flipping movement is performed according to the transformation of the X1Y1Z1 to X2Y2Z2 coordinate system (XYZ corresponds to each other). The flipped bale is placed on the left end of the standing plate 22 near the transition plate 146 where the temporary storage bale 53 is placed. As described above, the bale 53 to be stood is squeezed by the subsequent bale to the bale 54 to be stood. As described above, the bale 53 to be stood is squeezed by the subsequent bale to the bale 55 to be stood. The three bales move in direction two. Preferably, three flipped bales are arranged on the standing plate 22.

[0062] The bales 55 to be erected are detected by the displacement sensor 23, and the detection signal is transmitted to the erecting cylinder 22, and the erecting plate 22 generates a flipping action. The bales to be erected are flipped on the erecting plate 22, and stand up under the action of the bale baffle 32. The bales in groups of three are flipped according to the transformation of the X3Y3Z3 to X4Y4Z4 coordinate system (XYZ), and the hydraulic motor drives the drive chain. After running 360 degrees, the bales on the temporary storage platform 35 are pushed out of the temporary storage platform 35.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
