Description

A vehicle-mounted hopper-type tobacco leaf collection device and method Technical Field

[0001] This invention relates to the field of tobacco harvesting technology, and in particular to a vehicle-mounted hopper-type tobacco leaf collection device and method. Background Technology

[0002] Currently, tobacco leaf picking and collection are mostly done manually. The harvesting season coincides with the hottest part of summer, and the working environment is harsh. The picked tobacco leaves need to be carried from the fields to the collection point by hand, which is labor-intensive and makes it difficult to ensure timely harvesting. At the same time, the quality of the harvested tobacco leaves is affected by unpredictable weather.

[0003] The emergence of fully automatic tobacco harvesters has reduced the use of manpower, but overall the harvesting effect is not good, with problems such as damage, missed harvesting, and under-harvesting failing to meet requirements.

[0004] High-clearance self-propelled harvesters, used in conjunction with manual harvesting, can significantly reduce the labor intensity of field handling while ensuring the quality of tobacco leaves. However, for long tobacco fields, the existing harvester collection devices have limited capacity, requiring the harvested tobacco leaves to be unloaded midway and then transported back to the field by manpower or other transport machinery. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a vehicle-mounted hopper-type tobacco leaf collection device and method. This invention increases the tobacco leaf collection capacity by setting up a three-layer tobacco leaf hopper and cooperating with a lifting mechanism, avoiding the need to unload tobacco midway and improving harvesting efficiency. To achieve the above objective, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides a vehicle-mounted hopper-type tobacco leaf collection device, comprising a self-propelled harvester equipped with a support frame, wherein a collection unit is provided on both sides of the support frame; each collection unit includes:

[0007] The first tobacco rack is fixed in place and can hold at least one tobacco hopper.

[0008] The second tobacco rack can hold at least one tobacco hopper.

[0009] The third tobacco rack can hold at least one tobacco hopper; in the initial state, the tobacco hoppers placed on the third tobacco rack, the second tobacco rack, and the first tobacco rack are stacked sequentially from top to bottom.

[0010] The lifting mechanism has a winch that passes through the second tobacco rack and connects to the third tobacco rack. Under the traction of the winch, the third tobacco rack is lifted to a first set height, which can drive the second tobacco rack to rise synchronously to a second set height, so that there is a set layer spacing between the three layers of tobacco hoppers.

[0011] As a further implementation, the first cigarette holder is mounted on the support bracket, the second cigarette holder is slidably mounted on the first cigarette holder, and the third cigarette holder is slidably mounted on the second cigarette holder.

[0012] As a further implementation, the first cigarette holder is a frame structure with first guide grooves inside the supports on both sides; the second cigarette holder is a frame structure with second guide wheels on the outer sides of the supports on both sides, and the first guide grooves cooperate with the second guide wheels.

[0013] As a further implementation, the third cigarette holder is a frame structure with third guide wheels on both sides of the support, and second guide grooves are provided on the inner sides of both sides of the second cigarette holder, with the second guide grooves cooperating with the third guide wheels.

[0014] As a further implementation, the lifting mechanism is mounted on the top crossbeam of the first smoke rack, and the winch passes through the top crossbeam of the second smoke rack and connects to the top crossbeam of the third smoke rack.

[0015] As a further implementation, the third tobacco rack, the second tobacco rack, and the first tobacco rack can each hold two tobacco hoppers.

[0016] As a further implementation, the third tobacco rack, the second tobacco rack, and the first tobacco rack are all provided with transverse support rails and arranged sequentially from top to bottom, with the tobacco hoppers of each layer set on the support rails.

[0017] As a further implementation, each of the tobacco hoppers is provided with a hook on the upper part, which is connected to the support slide rail.

[0018] As a further implementation, the tobacco hopper has a U-shaped structure.

[0019] In a second aspect, the present invention provides a method for operating the vehicle-mounted hopper-type tobacco leaf collection device according to the first aspect, comprising the following steps:

[0020] Initially, the tobacco hoppers placed on the third, second, and first tobacco racks are stacked sequentially from top to bottom. Manually harvested tobacco leaves are first placed into the tobacco hopper on the third tobacco rack in order. Once the hopper is full, the winch is activated to pull the third tobacco rack, and the full tobacco hopper on it is raised to the traction position of the second tobacco rack. Subsequently harvested tobacco leaves are placed into the tobacco hopper on the second tobacco rack. Once the hopper is full, the winch is activated to pull the third and second tobacco racks to the set position simultaneously. Finally, the harvested tobacco leaves are placed into the tobacco hopper on the first tobacco rack.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The self-propelled harvester of this invention features two symmetrically arranged collection units on both sides. Each collection unit is equipped with a first tobacco rack, a second tobacco rack, and a third tobacco rack. Each tobacco rack has at least one tobacco hopper, forming three layers of tobacco hoppers, which are initially stacked in three layers. A lifting mechanism is also provided. When the tobacco hopper of the upper layer is full, it can be lifted by the lifting mechanism to fill the tobacco hopper of the next layer. Therefore, with the assistance of the lifting mechanism, the three layers of tobacco hoppers increase the tobacco collection capacity, avoid unloading tobacco midway, and improve harvesting efficiency.

[0023] 2. The third, second, and first tobacco racks of this invention are all provided with transverse support rails and are arranged sequentially from top to bottom. The tobacco hoppers of each layer are set on the support rails. The setting of the support rails allows each tobacco rack to carry more tobacco hoppers, thereby enabling the device to store and transport more tobacco leaves.

[0024] 3. The sliding arrangement of the three tobacco racks and the design of the height of the tobacco racks in this invention, under the traction of the lifting mechanism, can drive the second tobacco rack to rise synchronously after the third tobacco rack is lifted to the set height, so that there is a set layer spacing between the three layers of tobacco hoppers, ensuring that the three layers of tobacco hoppers do not interfere with each other when in use.

[0025] 4. The present invention is equipped with baffles, fixing sleeves, anti-detachment plates and anti-return baffles, which can realize the relative fixation of the tobacco hopper in the track groove, prevent the tobacco hopper from accidentally sliding or falling off during the harvesting process, and ensure safety.

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] Example 1

[0039] In a typical embodiment of the present invention, referring to Figure 1, a vehicle-mounted hopper-type tobacco leaf collection device includes a self-propelled harvester 1 with a support frame. A collection unit is provided on each side of the support frame. The self-propelled harvester is a tracked harvester, and any existing harvester can be used. In this embodiment, the two collection units are symmetrically arranged. Specifically, the support frame is fixedly mounted on the self-propelled harvester 1 and is formed by connecting two U-shaped frames. A collection unit is provided on each side of the support frame and arranged symmetrically.

[0040] Each collection unit includes a first smoke rack 2, a second smoke rack 3, a third smoke rack 4, and a lifting mechanism 5.

[0041] As shown in Figure 1, a first tobacco rack 2 is fixedly installed, on which at least one tobacco hopper 6 can be placed; a second tobacco rack 3 can also place at least one tobacco hopper 6; and a third tobacco rack 4 can also place at least one tobacco hopper 6. In this embodiment, each of the first tobacco rack 2, the second tobacco rack 3, and the third tobacco rack 4 is provided with two tobacco hoppers 6. In the initial state, the tobacco hoppers 6 placed on the third tobacco rack 4, the second tobacco rack 3, and the first tobacco rack 2 are stacked sequentially from top to bottom.

[0042] As shown in Figures 1 and 2, the first cigarette rack 2 is mounted on the support bracket, the second cigarette rack 3 is slidably mounted on the first cigarette rack 2, and the third cigarette rack 4 is slidably mounted on the second cigarette rack 3.

[0043] As shown in Figure 2, in this embodiment, the first cigarette rack 2 specifically includes a first cigarette rack body 21, which is a frame structure, specifically a U-shaped frame structure, with first guide grooves 24 provided in the side supports; and several fixed supports 22 are also provided on the side supports for fixed connection with the supporting supports.

[0044] Specifically, the two vertical support rods of the first cigarette rack 2 are U-shaped support rods, and the first guide groove 24 is located on the inner side of the support rod; the fixed bracket 22 is located on the outer side of the support rod. In this embodiment, each vertical support rod has three fixed brackets 22 on its outer side, and the fixed connection with the load-bearing bracket is achieved by the fixed brackets 22 and bolts.

[0045] As shown in Figure 3, in this embodiment, the second cigarette rack 3 specifically includes a second cigarette rack body 31. The second cigarette rack body 31 is a frame structure, also a U-shaped frame structure. The outer side of the vertically arranged brackets on both sides of the second cigarette rack body 31 is provided with second guide wheels 34. One second guide wheel 34 is provided at the upper end and one at the lower end of each side bracket. The second cigarette rack body 31 cooperates with the first guide groove 24 through the second guide wheels 34, thereby realizing the sliding installation of the second cigarette rack 3 on the first cigarette rack 2.

[0046] The vertical supports on both sides of the second cigarette holder body 31 are also U-shaped support rods, thus forming a second guide groove 33 on the inner side of the supports on both sides of the second cigarette holder 3.

[0047] As shown in Figure 4, the third cigarette rack 4 specifically includes a third cigarette rack body 41. The third cigarette rack body 41 is a frame structure, also a U-shaped structure. The supports on both sides are equipped with third guide wheels 43. The second guide groove 33 cooperates with the third guide wheel 43, thereby realizing the sliding installation of the third cigarette rack 4 on the second cigarette rack 3.

[0048] As shown in Figure 4, both the upper and lower crossbeams of the third smoke rack 4 are equipped with shock absorbers 42 to reduce damage after a collision and to provide a buffering effect.

[0049] As shown in Figure 8, the tobacco leaf collecting device also includes a lifting mechanism 5, specifically comprising a winch and a cable wound around it. The winch is mounted on the top crossbeam of the first tobacco rack 2, and the cable passes through the second tobacco rack 3 and connects to the third tobacco rack 4. Under the traction of the cable, the third tobacco rack 4 is lifted to a first predetermined height, which in turn causes the second tobacco rack 3 to rise synchronously to a second predetermined height, so that there is a predetermined spacing between the three layers of tobacco leaf hoppers 6. The first predetermined height is the height at which the top crossbeam of the third tobacco rack 4 contacts the top crossbeam of the second tobacco rack 3; further lifting at this height will cause the second tobacco rack 3 to rise synchronously. The second predetermined height is the height at which the top crossbeam of the second tobacco rack 3 contacts the top crossbeam of the first tobacco rack 2.

[0050] In this embodiment, the self-propelled harvester has two symmetrically arranged collection units on both sides. Each collection unit is equipped with a first tobacco rack 2, a second tobacco rack 3, and a third tobacco rack 4. Each tobacco rack has at least one tobacco hopper 6, forming three layers of tobacco hoppers, which are initially stacked in three layers. A lifting mechanism 5 is also provided. When the tobacco hopper 6 of the upper layer is full, it can be lifted by the lifting mechanism 5 to fill the tobacco hopper 6 of the next layer. Therefore, with the cooperation of the lifting mechanism 5, the three layers of tobacco hoppers 6 increase the tobacco collection capacity, avoid unloading tobacco midway, and improve harvesting efficiency.

[0051] As shown in Figures 2, 3, and 4, the first smoke rack 2, the second smoke rack 3, and the third smoke rack 4 decrease in vertical height sequentially. In the initial state, the top crossbeam of the first smoke rack 2 is the highest, followed by the second smoke rack 3, and the top crossbeam of the third smoke rack 4 is the lowest.

[0052] The winch of the lifting mechanism 5 is installed on the top crossbeam of the first smoke frame 2, and the winch cable passes through the through hole on the top crossbeam of the second smoke frame 3 and is connected to the lifting lug on the top crossbeam of the third smoke frame 4.

[0053] The third tobacco rack 4, the second tobacco rack 3, and the first tobacco rack 2 are all equipped with horizontal support rails arranged sequentially from top to bottom, and the tobacco hoppers 6 of each layer are placed on the support rails. The first tobacco rack 2 is equipped with a first support rail 23, the second tobacco rack 3 is equipped with a second support rail 32, and the third tobacco rack 4 is equipped with a third support rail 44. Specifically, it should be ensured that in the initial state, the third support rail 44 is positioned above the second support rail 32, and the second support rail 32 is positioned above the first support rail 23. In this embodiment, the two tobacco hoppers 6 of each layer are arranged on the support rails without overlap. For example, after the tobacco hopper on a certain layer's support rail is full, it can be pushed to the rear end of the support rail, and then the second tobacco hopper of that layer can be filled. Initially, only one tobacco hopper can be placed on each layer. If two are needed, the other tobacco hopper can be hung on the support rail. After the first one is full, it can be pushed to the rear end, and then the second one can be collected. Initially, two can also be placed on each layer, depending on the actual situation.

[0054] In this embodiment, each tobacco hopper 6 is provided with two hooks on the upper part, which are connected to the support slide rail.

[0055] In this embodiment, the third tobacco rack 4, the second tobacco rack 3, and the first tobacco rack 2 are all equipped with transverse support rails and are arranged sequentially from top to bottom. The tobacco hoppers 6 of each layer are set on the support rails. The setting of the support rails allows each tobacco rack to carry more tobacco hoppers 6, thereby enabling the device to store and transport more tobacco leaves.

[0056] In this embodiment, the tobacco hopper 6 has a U-shaped structure, with the upper opening being larger than the bottom opening, a smooth inner wall, and an overall thin-plate structure.

[0057] As shown in Figure 5, the three support slide rails have the same structure. This embodiment will be described using the first support slide rail 23. The first support slide rail 23 includes a slide rail body 231, a baffle 232, an anti-detachment plate 233, an anti-reverse baffle 234, and a fixing sleeve 235.

[0058] The slide rail body 231 is provided with a track groove, in which the hooks of the tobacco hopper 6 can be placed. The hooks can slide in the groove, and the top of each tobacco hopper 6 is hung in the track groove by the hooks at both ends.

[0059] A baffle 232 is located at the rear end of the track groove to prevent the hook from coming off from the rear end and to limit the sliding distance of the tobacco hopper 6 to the rear end. An anti-detachment plate 233 is located at the middle lateral position of the slide rail body 231. The anti-detachment plate 233 is L-shaped, so it can form an abutment plate above the track groove. Its height is just enough to abut one of the hooks of the tobacco hopper 6 from above, preventing the hook from coming off from the top of the track groove.

[0060] The anti-reverse baffle 234 is installed in the track groove. One end of it is fixed to the track groove, and the other end extends obliquely to the middle position in the width direction of the track groove. The purpose is to allow the hook to pass through the anti-reverse baffle 234 in one direction. When the hook slides in the opposite direction, the anti-reverse baffle 234 can block the hook. Therefore, the anti-reverse baffle 234 can prevent the tobacco hopper 6 at the rear end from returning to the front end.

[0061] As shown in Figure 6, the fixed sleeve 235 is located at the front end of the track groove. When the first tobacco hopper 6 is hung in the track groove using the hook, the hook at the front end first engages with the fixed sleeve 235, that is, the hook 8 is hung in the fixed sleeve 235, which can prevent the tobacco hopper 6 from sliding randomly. When the first tobacco hopper 6 is full of tobacco leaves, the hook here is lifted, the tobacco hopper 6 is slid backward, and the hook is hung in the track groove again. At this time, the first tobacco hopper 6 can slide backward.

[0062] Understandably, after the first tobacco hopper 6 is filled with tobacco leaves, it slides backward, and the hook at the rear end of the first tobacco hopper 6 is blocked by the baffle 232. The distance from the anti-detachment plate 233 to the baffle 232 is equal to the distance between the two hooks on the tobacco hopper 6. Therefore, when the first tobacco hopper 6 is filled with tobacco leaves and slides to the rear end of the track groove, the hook at the rear end is blocked by the baffle 232, and the hook at the front end is restricted by the anti-detachment plate 233. Then, the second tobacco hopper 6 is assembled. The hook at the front end of the second tobacco hopper 6 is fixed in place with the fixing sleeve 235. The hook at the rear end of the second tobacco hopper 6 can also be located in the track groove below the anti-detachment plate 233 at this time, and the two tobacco hoppers 6 can abut against each other, so that the position of the tobacco hopper 6 on the slide rail body 231 can be relatively fixed, and the tobacco hopper 6 will not fall off due to the bumps when the self-propelled harvester moves forward, thus ensuring safety during the harvesting process.

[0063] Example 2

[0064] This embodiment provides a method for operating the vehicle-mounted hopper-type tobacco leaf collection device according to Embodiment 1, including the following steps, as shown in Figures 1 and 7:

[0065] Initially, the tobacco hoppers 6 placed on the third tobacco rack 4, the second tobacco rack 3, and the first tobacco rack 2 are stacked sequentially from top to bottom. Manually harvested tobacco leaves 7 are first placed into the tobacco hopper 6 on the third tobacco rack 4 in sequence. After it is full (the tobacco hoppers numbered 1 and 2 are placed in sequence), the winch is activated to pull the third tobacco rack 4, and the full tobacco hopper 6 on it is raised to the traction position of the second tobacco rack 3, which is the first set height. The continuously harvested tobacco leaves 7 are then placed into the tobacco hopper 6 on the second tobacco rack 3. After it is full (the tobacco hoppers numbered 3 and 4 are placed in sequence), the winch is activated to pull the third tobacco rack 4 and the second tobacco rack 3 to the set position, which is the second set height. Subsequently, the harvested tobacco leaves 7 are placed into the tobacco hopper 6 on the first tobacco rack 2 (the tobacco hoppers numbered 5 and 6 are placed in sequence).

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
