Description

Technical Field

[0001] This utility model relates to the technical field of tobacco topping devices, specifically to a tobacco topping and collecting device. Background Technology

[0002] Once tobacco plants reach maturity and develop flower buds, they transition from vegetative to reproductive growth. This causes a significant amount of nutrients to flow to the apical inflorescence, negatively impacting leaf growth and significantly reducing yield and quality. Topping techniques are commonly used to eliminate apical dominance and inhibit reproductive growth. The primary method of topping tobacco involves using a topping device to remove the apical flowers and other growth plates from the top of the plant.

[0003] Publication No. CN114080918A discloses a method and equipment for mechanized topping of tobacco. During mechanical operation, after the tobacco plant enters the comb-shaped tobacco leaf separation support, the upper tobacco leaves are guided to the lower side of the separator by the action of the comb-shaped tobacco leaf separator, so that they will not be damaged by the topping knife. The top main stem and inflorescence to be cut are exposed on the upper part of the separator and are held by the serrated blade of the rear rotating topping knife. The force rod rotates towards the blade. When the force rod contacts the groove of the blade, the top main stem and inflorescence are cut off from the main stem. The cut top main stem and inflorescence move to the rear collector under the action of the force rod. In the collector, they are packaged and transported out of the tobacco field.

[0004] However, this topping device requires first separating the top inflorescence from the usable tobacco leaves using a comb-shaped tobacco leaf separator, and then pressing the top inflorescence against the serrated cutting blade using a rotating force rod, where it works together with the serrated cutting blade to cut the top inflorescence. Although it can achieve the functions of cutting the top of tobacco, avoiding damage to usable tobacco leaves, and recycling the cut top of tobacco, it requires a separate structure to separate the usable tobacco leaves from the topping area and the cutting structure, resulting in a relatively complex structure and high cost. It also has high requirements for the flatness of the field and the uniformity of the tobacco leaves in the field. It is suitable for users with good overall field conditions (flat fields, high contiguous area) and large-scale tobacco planting. For small tobacco growers or tobacco fields with special topography in mountainous and hilly areas (large field slope, low contiguous area, large drop between field ridges, etc.), it increases the equipment investment cost and faces the dilemma of having no alternative equipment. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a tobacco topping and flower collection device. This solves the problem that the existing topping device requires an independent structure and cutting structure to separate the useful tobacco leaves from the topping area, resulting in a relatively complex structure and high cost. It is only suitable for users with large-scale tobacco planting and good overall tobacco field conditions. For small tobacco growers, it increases the technical problem of equipment investment costs.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a tobacco topping and collecting device, comprising:

[0008] The flower collection section has a receiving cavity;

[0009] The flexible part has a connecting channel that communicates with the receiving cavity;

[0010] The top has an inner cavity with an opening on one side, the inner cavity communicating with the end of the connecting channel away from the receiving cavity; and

[0011] The cutting part is movably disposed on the top of the machine and has a cutting position and an avoidance position in the moving stroke. When the cutting part is in the cutting position, it can cut off the material that enters the inner cavity through the opening and block the opening. When it is in the avoidance position, it opens the opening.

[0012] In some embodiments, the top of the punch has a connection port communicating with the connection channel, and a guide channel communicating with the outside and the inner cavity, the guide channel being located on the side of the top of the punch close to the opening;

[0013] The cutting part can extend into and retract from the inner cavity through the guide channel, and is in the cutting position when it extends into the inner cavity and blocks the opening, and is in the avoidance position when it retracts from the inner cavity.

[0014] In some embodiments, the tobacco topping and collecting device further includes an elastic element that connects the cutting part and the topping part, and can drive the cutting part to elastically return from the avoidance position to the cutting position.

[0015] In some embodiments, the outer wall of the top of the cutting portion is provided with a mounting base, which extends along the direction of movement of the cutting portion;

[0016] The tobacco top-collecting device also includes a control arm and a stop block. One end of the control arm is connected to the cutting part and can rotate relative to the cutting part around its direction of movement. The stop block is located on the control arm and spaced apart from the cutting part. When the cutting part is in the avoidance position, it can be stopped on the side of the mounting base away from the inner cavity.

[0017] In some embodiments, the control arm extends along the direction of movement of the cutting portion, and an anti-slip stripe is provided at the end away from the cutting portion.

[0018] In some embodiments, a limiting plate is provided at one end of the mounting base away from the inner cavity. The limiting plate and the cutting part are located on the same side of the limiting plate and on the side of the cutting part away from the inner cavity, for blocking the cutting part.

[0019] In some embodiments, the limiting plate is provided with a sliding channel in a direction away from the inner cavity, and the sliding channel is open on the side away from the mounting base;

[0020] The control arm is slidably disposed in the sliding channel, and the stop block can pass through the opening of the sliding channel.

[0021] In some embodiments, the top is a transparent top, and its outer wall surface is provided with scale lines, the extension direction of which is perpendicular to the plane where the opening is located.

[0022] In some embodiments, the tobacco topping and collecting device further includes a handle, which is mounted on the outer wall of the top and located on both sides opposite to the scale line to the cutting part.

[0023] In some embodiments, the tobacco topping and collecting device further includes a belt connected to the outer wall of the collecting part.

[0024] Compared with the prior art, when using the tobacco topping and collecting device provided by this utility model, the topping operator first moves the cutting part to a clearance position to open the opening of the topping part; based on the soft characteristics of the flexible part, the topping part can be flipped over and the opening of the topping part can be flipped downwards and covered on the top of the tobacco that needs to be topped, so that the top of the tobacco can enter its inner cavity through the opening of the topping part, while the tobacco leaves that do not need to be cut are placed outside the inner cavity of the topping part.

[0025] Then, the cutting part moves from the avoidance position to the cutting position to cut off the top of the tobacco. At this time, the cutting part blocks the cut tobacco top in the inner cavity of the top-beating part, preventing the cut top from falling into the field from the opening of the top-beating part. Finally, the top-beating part is flipped over again so that the opening of the top-beating part faces upward. At this time, the cut tobacco top can fall along the connecting channel of the flexible part into the receiving cavity of the flower collection part.

[0026] Thus, this solution can cut off the top of the tobacco leaves by combining the top cutting and the cutting part, while avoiding accidental cutting of useful tobacco leaves. The cut tobacco top can be recycled into the receiving cavity of the flower collection part. Compared with the existing technology, no additional separation structure is required. The structure is relatively simple and the cost is low, which reduces the equipment investment cost for small tobacco growers. Moreover, the operation is simple and convenient.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] To address the technical problem that existing topping devices require separate structures for separating usable tobacco leaves from the topping area, as well as a cutting structure, resulting in relatively complex structures and high costs, making them suitable for large-scale tobacco cultivation but increasing equipment investment costs for small-scale tobacco growers, this invention provides a tobacco topping and collecting device. This device can cut off the top of the tobacco leaves, avoiding accidental cutting of usable leaves, and the cut top can be collected and stored in the collecting cavity. Operation is simple and convenient. Furthermore, its relatively simple structure and low cost reduce equipment investment costs for small-scale tobacco growers.

[0037] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2This is a schematic diagram of the structure of a tobacco topping and collecting device in one embodiment of the present invention. The tobacco topping and collecting device includes a collecting part 1, a flexible part 2, a topping top 3, and a cutting part 4. The collecting part 1 has a receiving cavity 1a. The flexible part 2 has a connecting channel that connects to the receiving cavity 1a. The topping top 3 has an inner cavity 3b with an opening 3a on one side, and the inner cavity 3b connects to the end of the connecting channel away from the receiving cavity 1a. The cutting part 4 is movably disposed on the topping top 3 and has a cutting position and an avoidance position in its moving stroke. When the cutting part 4 is in the cutting position, it can cut off the material that extends into the inner cavity 3b through the opening 3a and block the opening 3a. When it is in the avoidance position, it opens the opening 3a.

[0038] When using the tobacco topping and gathering device provided by this utility model, the topping operator first moves the cutting part 4 to a clearance position to open the opening 3a of the topping top 3; based on the soft characteristics of the flexible part 2, the topping top 3 can be flipped over, and the opening 3a of the topping top 3 can be flipped downwards and covered on the top of the tobacco that needs to be topped, so that the top of the tobacco can enter its inner cavity 3b through the opening 3a of the topping top 3, while the tobacco leaves that do not need to be cut are placed outside the inner cavity 3b of the topping top 3.

[0039] Then, the cutting part 4 moves from the avoidance position to the cutting position to cut off the top of the tobacco. At this time, the cutting part 4 blocks the cut tobacco top in the inner cavity 3b of the top-beating part 3, preventing the cut top from falling into the field from the opening 3a of the top-beating part 3. Finally, the top-beating part 3 is flipped over again so that the opening 3a of the top-beating part 3 faces upward. At this time, the cut tobacco top can fall along the connecting channel of the flexible part 2 into the receiving cavity 1a of the flower collecting part 1.

[0040] Thus, this solution can cut off the top of the tobacco by combining the top part 3 and the cutting part 4, while avoiding accidental cutting of useful tobacco leaves. The cut tobacco top can be recycled into the receiving cavity 1a of the flower collection part 1. Compared with the prior art, no additional separation structure is required. The structure is relatively simple and the cost is low, which reduces the equipment investment cost for small tobacco growers. Moreover, the operation is simple and convenient.

[0041] In one embodiment, please refer to Figure 3 The top part 3 has a connecting port 3c that connects to the connecting channel, and a guide channel 3d that connects the outside and the inner cavity 3b. The guide channel 3d is located on the side of the top part 3 near the opening 3a. The cutting part 4 can extend into and retract from the inner cavity 3b through the guide channel 3d. When it extends into the inner cavity 3b and blocks the opening 3a, it is in the cutting position, and when it retracts from the inner cavity 3b, it is in the avoidance position.

[0042] In this embodiment, the cutting part 4 can move along the guide channel 3d and extend into and retract from the inner cavity 3b of the top 3 via the guide channel 3d, improving the stability of the cutting part 4 and making the overall structure relatively compact. It should be noted that the cutting part 4 can be configured as a blade-type cutting structure, a shearing-type cutting structure, or a grinding wheel-type cutting structure. Specifically, in this solution, the cutting part 4 is a cutting blade 41.

[0043] Furthermore, the tobacco collecting part 1 can be configured as a tobacco collecting bucket, a tobacco collecting basket, or a tobacco collecting box. The top-beating part 3 can be configured as a seat, a bucket, or a cone with a cavity. The flexible part 2 is configured as a flexible tube, which can be configured as a rubber tube, a corrugated tube, or a bladder with openings 3a at both ends. Specifically, in this embodiment, the tobacco collecting part 1 is configured as a tobacco collecting basket to reduce weight; and a carrying strap or waist belt 8 is provided on the tobacco collecting basket for easy carrying by the top-beating personnel. The top-beating part 3 is configured as a semi-cone with a cavity, which facilitates guiding the top of the tobacco into the inner cavity 3b of the top-beating part 3, and also facilitates the cutting blade 41 pressing against the planar side wall of the top-beating part 3, thereby facilitating the cutting of the tobacco top. The flexible part 2 is configured as a corrugated tube with a skeleton, which facilitates bending and reduces the contact resistance between the top of the cut tobacco pellets and the corrugated tube, facilitating the top to move down into the tobacco collecting basket.

[0044] It should be noted that, in one embodiment, the diameter of the opening 3a at the top 3 is set to 25-30 cm, the diameter of the connecting port 3c is set to 10-15 cm, and the inner diameter of the corrugated pipe is set to 10-15 cm.

[0045] In one embodiment, the tobacco topping and collecting device further includes an elastic element 5, which connects the cutting part 4 and the topping part 3, and can drive the cutting part 4 to elastically return from the avoidance position to the cutting position.

[0046] In this embodiment, after the top of the tobacco enters the inner cavity 3b through the opening 3a of the top 3 and the useful tobacco leaf is removed, the cutting part 4 can be released. Under the drive of the elastic member 5, the cutting part 4 can automatically return to the cutting position to shorten the top of the tobacco and cover the opening 3a, improving convenience. It should be noted that the elastic member 5 can be set as a compression spring 51, a leaf spring, or a gas spring. Specifically, in this solution, the elastic member 5 is a compression spring 51.

[0047] In one embodiment, please refer to Figures 4 to 6The outer wall of the top of the tobacco top is provided with a mounting base 31, which extends along the movement direction of the cutting part 4. The tobacco top collecting device also includes a control arm 6 and a stop block 61. One end of the control arm 6 is connected to the cutting part 4 and can rotate relative to the cutting part 4 around its movement direction. The stop block 61 is provided on the control arm 6 and spaced apart from the cutting part 4. When the cutting part 4 is in the avoidance position, it can be stopped on the side of the mounting base 31 away from the inner cavity 3b.

[0048] In this embodiment, the control arm 6 is first rotated to rotate the stop block 61 to a position that avoids the mounting base 31. Then, the control arm 6 pulls the cutting part 4 away from the inner cavity 3b of the top of the tobacco 3 from the guide channel 3d. When the cutting part 4 retracts from the inner cavity 3b to a preset position, the stop block 61 moves to the side of the mounting base 31 away from the inner cavity 3b, and the compression spring 51 is compressed. Then, the control arm 6 is rotated again to rotate the stop block 61 to be stopped by the mounting base 31, preventing the cutting part 4 from extending into the inner cavity 3b. After the top of the tobacco enters the inner cavity 3b of the top of the tobacco 3 and the useful tobacco leaves are removed, the control arm 6 is rotated again to disengage the stop block 61 from the mounting base 31. At this time, the cutting part 4 enters the inner cavity 3b under the drive of the compression spring 51, completing the cutting.

[0049] Specifically, in this embodiment, the mounting base 31 is provided with a channel 31a for mounting the compression spring 51, and the channel 31a communicates with the inner cavity 3b; correspondingly, the cutting part 4 has a protrusion extending into the channel 31a, and the compression spring 51 connects the protrusion and the inner wall of the channel 31a.

[0050] In one embodiment, the control arm 6 extends along the direction of movement of the cutting section 4, and the end of it away from the cutting section 4 is provided with anti-slip stripes.

[0051] In this embodiment, anti-slip stripes are provided on the control arm 6 to facilitate operator pulling and movement, improving convenience. Specifically, in this embodiment, the axial direction of the control arm 6 is consistent with the direction of movement of the cutting section 4.

[0052] In one embodiment, a limiting plate 32 is provided at the end of the mounting base 31 away from the inner cavity 3b. The limiting plate 32 and the cutting part 4 are located on the same side of the limiting plate 32 and on the side of the cutting part 4 away from the inner cavity 3b, which is used to block the cutting part 4.

[0053] In this embodiment, the cutting part 4 can be stopped by the limiting plate 32, which prevents the entire self-guided channel 3d of the cutting part 4 from detaching from the top 3, thereby improving the stability of the cutting part 4.

[0054] In one embodiment, the limiting plate 32 is provided with a sliding channel 32a in the direction away from the inner cavity 3b, and the sliding channel 32a is open on the side away from the mounting base 31; the control arm 6 is slidably disposed in the sliding channel 32a, and the stop block 61 can pass through the opening of the sliding channel 32a.

[0055] In this embodiment, the control arm 6 is also slidably disposed in the sliding channel 32a to prevent the control arm 6 from deviating during movement and hindering the movement of the cutting part 4, thereby improving the stability of the movement of the cutting part 4.

[0056] In one embodiment, the top 3 is transparent, and its outer wall surface is provided with scale lines 33, the extension direction of the scale lines 33 being perpendicular to the plane where the opening 3a is located.

[0057] In this embodiment, the top of the tobacco cutting device 3 is made of transparent material so that the operator can intuitively see the tobacco top extending into the top of the tobacco cutting device 3. Scale lines 33 are set on the outer wall of the top of the tobacco cutting device 3 so that the operator can quickly adjust to the height at which the tobacco top needs to be cut, thereby improving the quality of the tobacco cutting.

[0058] In one embodiment, the tobacco topping and collecting device also includes a handle 7, which is installed on the outer wall of the top 3 and is located on both sides opposite to the cutting part 4 on the scale line 33.

[0059] In this embodiment, the handle 7 and the cutting part 4 are placed on both sides of the scale line 33, so that the operator can hold the handle 7 and the cutting part 4 with both hands respectively, without affecting the operator's observation of the scale line 33.

[0060] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:

[0061] In this scheme, the operator first pulls the control arm 6 to retract the cutting blade 41 from the inner cavity 3b, thereby opening the opening 3a of the top-cutting 3. Then, the operator rotates the control arm 6 so that the stop block 61 is blocked by the limiting plate 32 and the mounting base 31. At this time, the compression spring 51 is compressed. Based on the flexible characteristics of the bellows, the top-cutting 3 can be flipped over, and the opening 3a of the top-cutting 3 can be flipped downwards and placed over the top of the tobacco to be topped. This allows the top of the tobacco to enter its inner cavity 3b through the opening 3a of the top-cutting 3, and the top is extended to the preset position according to the scale line 33. At the same time, the tobacco leaves that do not need to be cut are pushed out of the inner cavity 3b of the top-cutting 3.

[0062] Then, rotate the control arm 6 again to disengage the stop block 61 from the limiting plate 32 and the mounting base 31. At this time, the cutting blade 41, driven by the compression spring 51, automatically enters the inner cavity 3b to cut off the top of the tobacco and block the opening 3a of the top-beating 3. The cutting blade 41 then prevents the cut tobacco top from falling into the field through the opening 3a of the top-beating 3. Finally, flip the top-beating 3 again so that the opening 3a faces upwards. At this time, the cut tobacco top can fall along the corrugated tube into the receiving cavity 1a of the collecting section 1.

[0063] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
