Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a tobacco field ground film peeling and recovery device. Background Art

[0002] At present, the production of flue-cured tobacco adopts the method of covering the ridge with mulch, mostly with black and white mulch, and most of the mulch has been made of degradable mulch, which can degrade in the natural environment for more than a few years. The main functions of mulch covering in tobacco fields are: first, when transplanting, the ridge of the transplanting tobacco seedlings can be covered with mulch to increase the temperature of the ridge, so as to promote the early growth of the tobacco seedlings after transplanting to the ridge; second, by covering with mulch, especially covering with black and white mulch, the black part covers the ridge, which can inhibit the growth of weeds under the film, achieve the purpose of weeding the ridge, and provide a good growth environment for the growth of tobacco seedlings. The period when mulch covering works is mainly from the transplanting of tobacco seedlings to the vigorous growth period of tobacco seedlings, which is about 40 days. As the tobacco plants enter the vigorous growth period and mature period, the ambient temperature rises, the heat preservation effect of the mulch gradually weakens, and the excessively high temperature will affect the growth and development of the root system of the tobacco plants, which requires timely film removal and recycling. At present, the film removal method used in production is manual film removal, and then centralized transportation and recycling by vehicles. Manual film removal not only causes the film to be easily damaged, but also contains a lot of soil, which is not conducive to centralized recycling.

[0027] See also Figures 1 to 7, Embodiment 1, the present invention provides a tobacco field mulch film peeling and recovery device, comprising a support frame 1, a bottom wheel 2, an upper wheel 3 and a mulch film splitter 4, wherein one end of the support frame 1 is provided with a first axis 11 and a second axis 12 parallel to each other, the bottom wheel 2 is axially fixedly mounted on the first axis 11 in a circumferential rotation direction, and the upper wheel 3 is axially fixedly mounted on the second axis 12 in a circumferential rotation direction, the bottom wheel 2 is provided with a first gear 21 at one end close to the support frame 1, and the upper wheel 3 is provided with a second gear 31 at one end close to the support frame 1, the first gear 21 and the second gear 31 are located on the same plane, the first gear 21 and the second gear 31 are meshed or the first gear 21 and the second gear 31 are connected by a chain, and the bottom wheel 2 rolls on the ground to drive the transmission chain or gear to provide power to the upper wheel 3, and the bottom wheel 2 drives the upper wheel 3 to rotate, and it is also possible to make the first gear and the second gear have the same number of teeth, so that the bottom wheel and the upper wheel rotate synchronously, the mulch film splitter 4 is arranged at one end of the first axis 11 away from the support frame 1, and the mulch film splitter 4 is arranged between the bottom wheel 2 and the upper wheel 3. When the device is used to remove the film, damage to the film can be prevented, so that the recycling is more thorough and the efficiency of film recycling is greatly improved, saving labor input for tobacco farmers. At the same time, the device has a simple structure, is easy to make and easy to operate.

[0028] As a further improvement to the above technical solution, it also includes a brush 5, which is installed on the support frame 1 through a bracket 51, and is arranged parallel to the upper wheel 3. The brush 5 is installed between the upper wheel 3 and the bottom wheel 2, and the brush 5 is installed inwardly, so as to facilitate cleaning the soil on the ground film before rolling it up. The brush 5 is arranged to clean the soil attached to the ground film when the film is peeled off, which reduces the cost investment for the subsequent reuse of the ground film, and is more conducive to the uniform rolling of the ground film on the upper wheel 3.

[0029] As a further improvement to the above technical solution, the bracket 51 is "L" shaped, the long side of the bracket 51 is vertically arranged on the second shaft 12, the brush 5 is fixedly arranged on the long side of the bracket 51, two brushes 5 are arranged symmetrically, and the bristles of the two brushes 5 are opposite to each other, and the gap 52 between the bristles of the two brushes 5 is 4 to 8 mm. The two brushes 5 can be arranged to clean the soil on both sides of the ground film. Preferably, the bracket is hingedly arranged on the support frame.

[0030] As a further improvement of the above technical solution, the mulch splitter 4 has blades with cutting edges on both sides. The length of the mulch splitter 4 is 2 to 4 cm greater than the radius of the bottom wheel 2. The cutting edge is arranged at a position where the mulch splitter 4 exceeds the bottom wheel 2. One end of the mulch splitter 4 is fixed on the first axis by bolts and the other end is suspended. The mulch divider is rotatably arranged on the first shaft, and the mulch divider can rotate around the axis of the first shaft. A positioning hole is arranged on the mulch divider, and a plurality of threaded holes corresponding to the positioning holes are arranged on the end face of the first shaft. The mulch divider is fixed on the first shaft by screws. The angle of the mulch divider is adjusted by fixing the mulch divider to threaded holes at different positions, so that the mulch divider can smoothly divide the mulch when used by workers at different heights. When workers at different heights are removing the mulch, the support frame is at different angles to the horizontal plane. By adjusting the angle of the mulch divider, the mulch divider is always kept at a similar angle to facilitate cutting the mulch. The angle formed by two adjacent threaded holes and the axis of the first shaft is 10 degrees, that is, the mulch divider can be rotated 10 degrees each time the position of a threaded hole is adjusted. There is a gap between the mulch divider and the bottom wheel to prevent the mulch divider from interfering with the rotation of the bottom wheel.

[0031] As a further improvement to the above technical solution, the support frame 1 is further provided with a handle 6 at one end away from the bottom wheel 2, and the gripping part of the handle 6 is provided with a wooden handle, which is convenient for holding. The handle 6 can be directly pulled from the front or pushed from the back by a human, so as to move the support frame 1, and the bottom wheel 2 rolls on the ground during the movement. Preferably, the handle 6 is controlled to be at the middle end of the roller, so that the force is more even when the film is peeled off, and it is convenient for workers to pull the roller to move.

[0032] As a further improvement to the above technical solution, the bottom wheel 2 and the upper wheel 3 are both wooden rollers. Preferably, the diameter of the upper wheel 3 is set to match the inner hole of the ground film barrel core, and the ground film barrel core can be directly fixed on the upper wheel 3 for ground film recycling. After the ground film recycling is completed, the ground film and barrel core can be directly disassembled and recycled to improve the use efficiency.

[0033] Instructions for use: When peeling and recycling the ground film, at one end of the ridge, the bottom wheel 2 goes deep from one side of the ground film, and one end of the lifted ground film passes through the gap between the two brushes 5 and is fixed on the upper wheel 3. The ground film on the ridge is divided into two by the ground film divider 4. The bottom wheel 2 rotates to separate the ground film from the surface soil, and drives the upper wheel 3 to rotate, and rolls the lifted ground film layer by layer on the upper wheel 3. Before peeling the film, the paper roll core of the original ground film needs to be inserted into the upper wheel 3, so that when peeling the film, the ground film is directly rolled on the paper roll core of the upper wheel 3. After peeling the film, the paper roll with the ground film is directly removed from the upper wheel 3 for centralized recycling.

[0034] In the second embodiment, the support frame 1 is provided with two sets, and the two sets of support frames 1 are symmetrically arranged. The two sets of support frames 1 are provided with a bottom wheel 2 and an upper wheel 3. The two sets of support frames 1 are connected by a connecting rod, and the connecting rod is arranged at an end away from the bottom wheel 2 and the upper wheel 3. One set of the support frames 1 is provided with a ground film splitter 4, and the upper wheel 3 on the support frame 1 without the ground film splitter 4 is longer. The distance between the end faces of the two suspended ends of the bottom wheels is the planting position of the tobacco, which is determined according to the planting position of the tobacco to prevent damage to the tobacco. The connecting rod can be set as a retractable rod to adjust its distance at any time. The two sets of support frames 1 can simultaneously recycle the ground film on both sides of the tobacco, divide the ground film from one side of the tobacco into two by the ground film splitter 4, and then separate the ground film on both sides of the tobacco from the ground by the two bottom wheels 2, and roll up the ground film on both sides of the tobacco by the two upper wheels 3 respectively. Preferably, the upper wheels 3 on the two support frames 1 can be connected and the height of the upper wheels 3 after rolling up the ground film is greater than the height of the tobacco. At the same time, the brush 5 is also connected and the height is greater than the height of the tobacco. Thus, a gear can be set on only one side of the support frame 1 to drive the rotation of the upper wheel 3. The ground film on both sides of the tobacco can be rolled up by the connected upper wheels 3 at the same time, thereby improving efficiency. The detachable connection between the two sets of support frames 1 facilitates the replacement of the barrel core on the upper wheel 3. It is also possible to connect one end of the upper wheel 3 and the brush 5 only to the support frame 1 on one side and overlap the other end on the support frame 1 on the other side for easy disassembly.
