Description

Technical Field

[0001] The utility model relates to the technical field of tobacco seedling planting, in particular to a self-propelled tobacco ridge film peeling machine. Background Art

[0002] Tobacco mulch planting technology is widely used. The mulch has the advantages of water saving, drought resistance, moisture increase and soil moisture retention, and weed control. When the time is right, the mulch needs to be removed in time. If the mulch is not removed in time, the tobacco seedlings are prone to high temperature burns in subsequent high temperature weather.

[0003] The Chinese utility model patent with authorization announcement number CN105660266B discloses a tobacco seedling film peeling machine, which includes a frame and a film rolling roller. The frame travels and the film rolling roller rotates synchronously to realize the continuous collection of the film on the tobacco ridge. Although it can reduce the intensity of manual labor, it still has the following problems: 1. Because the film is covered on the tobacco ridge with soil, the film is collected directly by the rotation of the film rolling roller, which makes it difficult to pull the film out of the soil sometimes. As the film rolling roller continues to pull the film hard, the film may damage the tobacco seedlings; 2. After a certain amount of film is collected by the film rolling roller, because the film is wound in multiple layers, the film is wound very tightly on the film rolling roller. Because the film rolling roller is fixed on the transmission shaft, the film collected on the film rolling roller is not easy to be quickly removed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with specific embodiments and attached Figure 1-8 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] The utility model provides a self-propelled tobacco ridge film peeling machine (such as Figure 1As shown), it includes an engine 1, a travel reducer 2, a travel mechanism, a film picking mechanism, and a film winding mechanism. The engine 1 and the travel reducer 2 are both well-known mature technologies in this technical field, so the working principle and detailed structure of the engine 1 and the travel reducer 2 are not described in detail. In this specific embodiment, the engine 1 can select a mature gasoline engine on the market, and the engine 1, the travel reducer 2, the film picking mechanism and the film winding mechanism are all arranged on the travel mechanism. The walking ability of the travel mechanism can facilitate the automatic walking of the film peeling machine above the chimney. The film picking mechanism includes a square film picking frame 41 and the square film picking frame 41 can rotate freely. After the film passes over the square film picking frame 41, during the clockwise rotation of the square film picking frame 41, it realizes the up and down shaking of the film, thereby facilitating The soil blocks on the film are shaken off. The film winding mechanism includes a cylindrical film winding frame 51 and the cylindrical film winding frame 51 can rotate freely. The free rotation of the cylindrical film winding frame 51 realizes the rotation and centralized collection of the film. The square film picking frame 41 is adjacent to the film feeding side of the cylindrical film winding frame 51, that is, the film on the chimney needs to be shaken by the square film picking frame 41 before entering the cylindrical film winding frame 51. The cylindrical film winding frame 51 can be transformed into a conical structure. When the cylindrical film winding frame 51 is transformed into a conical structure, it is easy to realize the detachment of the film roll wound on the cylindrical film winding frame 51, thereby improving the film collection efficiency; the engine 1 can provide walking power for the walking mechanism, and the engine 1 can provide rotational power for the square film picking frame 41 and the cylindrical film winding frame 51. In actual application, the square film picking frame 41 can be composed of three support rods and two square plates. The three support rods are distributed in the same plane, and then their corresponding ends are fixedly connected by a square plate. When the square film picking frame 41 and the cylindrical film winding frame 51 are installed on the walking mechanism, the height of the square film picking frame 41 can be made lower than the height of the cylindrical film winding frame 51 to ensure that when the square film picking frame 41 is in a vertical position, the height of its highest point is located between the height of the rotation axis of the cylindrical film winding frame 51 and the height of the lowest edge of the cylindrical film winding frame 51. In this way, during the rotation of the square film picking frame 41, not only can the film be picked up and down, but also when the square film picking frame 41 picks the film upward, the film between the square film picking frame 41 and the cylindrical film winding frame 51 can be tightened to a certain extent, thereby facilitating the tight winding of the film on the cylindrical film winding frame 51 and improving the ability of the cylindrical film winding frame 51 to collect the film 103 at one time.

[0027] When covering the film on the tobacco ridges, in order to prevent the film from being lifted by strong winds, generally, the two sides of the film are continuously buried with soil. At the same time, a certain amount of soil is stacked at intervals on the upper part of the film. When collecting the film using the present utility model, the shaking film function of the square film lifting frame 41 can be used to shake off the soil covering the upper part of the film. However, the cleaning effect of the soil continuously covering the two sides of the film using the shaking film function of the square film lifting frame 41 is not ideal. During the film uncovering process, in order to effectively clean the soil on both sides of the film and effectively separate the film from the soil on both sides, here, a film lifting mechanism is also provided on the film uncovering machine. The film lifting mechanism is arranged on the traveling mechanism and is located between the traveling speed reducer 2 and the square film lifting frame 41. That is, during the film uncovering process, it is ensured that the film is first separated from the soil on both sides, and then subsequent centralized collection of the film is carried out; the film lifting mechanism includes two film lifting knives 61 arranged opposite to each other left and right. The two film lifting knives 61 can move up and down reciprocally. The engine 1 provides power for the up and down reciprocal movement of the film lifting knives 61. In practical applications, the film lifting knives 61 are located on both sides of the film. The up and down reciprocal movement of the film lifting knives 61 cooperates with the linear movement of the traveling mechanism, thereby realizing the up and down cutting and loosening of the soil on both sides of the film, and thus effectively separating the film from the soil on both sides. After the film is effectively separated from the soil on both sides, the film is easily pulled flexibly, thereby avoiding the situation of the film being pulled hard and damaging the tobacco seedlings.

[0028] Based on the above embodiments, the specific implementation of the traveling mechanism is as follows: The traveling mechanism includes a front traveling bracket 31 and a rear traveling bracket 32. The front traveling bracket 31 and the rear traveling bracket 32 are fixedly connected in a detachable manner front and rear. The detachable connection between the front traveling bracket 31 and the rear traveling bracket 32 facilitates the use of the front traveling bracket 31 as a power traction bracket for other execution components, thereby achieving the purpose of multi-purpose use of one machine. The engine 1 and the traveling speed reducer 2 are arranged front and rear opposite to each other on the front traveling bracket 31. The film lifting mechanism, the square film picking frame 41 and the cylindrical film winding frame 51 are arranged in sequence from front to back on the rear traveling bracket 32. A traveling drive mechanism is arranged at the lower part of the front traveling bracket 31. In this specific embodiment, two specific embodiments of the traveling drive mechanism are designed. The specific implementation of the first specific embodiment of the traveling drive mechanism is as follows: A traveling drive shaft 21 penetrating through its left and right sides is arranged at the bottom of the traveling speed reducer 2. The traveling drive mechanism further includes a first traveling adjustment sleeve and a first traveling wheel. The first traveling adjustment sleeve is sleeved on the corresponding end of the traveling drive shaft 21 and the first traveling adjustment sleeve can be adjusted and positioned left and right relative to the traveling drive shaft 21. Specifically, a plurality of adjustment holes are arranged at the end of the traveling drive shaft 21, and positioning holes adapted to the adjustment holes are arranged on the first traveling adjustment sleeve. The adjustment and fixation of the first traveling adjustment sleeve are realized by penetrating a pin shaft through the positioning hole and the corresponding adjustment hole. The first traveling wheel is fixedly arranged at the end of the first traveling adjustment sleeve. In actual application, by adjusting the distance between the two first traveling wheels, the smooth traveling of the two first traveling wheels on both sides of the tobacco ridges with different widths is realized. By controlling the gear of the traveling speed reducer 2, the rotation speed of the first traveling wheel is controlled, and then the traveling speed of the front traveling bracket 31 is controlled. In the above first specific implementation manner of the traveling drive mechanism, the larger the diameter of the first traveling wheel, the larger the ground clearance of the front traveling bracket. Subsequently, it is convenient for the front traveling bracket 31 to travel above the tobacco ridges with different heights. However, under the condition that the rotation speed of the cylindrical film winding frame 51 remains unchanged, as the diameter of the first traveling wheel increases, the traveling speed of the front traveling bracket 31 increases. At this time, problems such as too loose film winding or film accumulation will occur, which is not conducive to the effective collection of the film. To ensure that the front traveling bracket 31 has a relatively high ground clearance and at the same time the traveling speed of the front traveling bracket 31 will not be too fast, the second specific implementation manner of the traveling drive mechanism is set here. Specifically, the traveling drive mechanism includes a second traveling adjustment sleeve 312, a transmission chain, a second traveling wheel 316, and two transmission protective covers 313. The second traveling adjustment sleeve 312 is sleeved on the corresponding end of the traveling drive shaft 21 and the second traveling adjustment sleeve 312 can be adjusted and positioned left and right relative to the traveling drive shaft 21. Specifically, a plurality of adjustment holes are arranged on the traveling drive shaft 21, and positioning holes are arranged on the second traveling adjustment sleeve 312.The pin shaft penetrates through the positioning hole and the corresponding adjustment hole to realize the adjustment and fixation of the second walking adjustment sleeve 312 on the walking drive shaft 21. The two transmission protective covers 313 are fixedly connected relatively. An upper sprocket and a lower sprocket distributed up and down are rotatably arranged inside the two transmission protective covers 313. The transmission chain is sleeved on the upper sprocket and the lower sprocket. The second walking wheel 316 is sleeved on the support shaft 315 sleeved in the lower sprocket. The second walking adjustment sleeve 312 is sleeved inside the upper sprocket. The second walking adjustment sleeve 312 can drive the upper sprocket to rotate. The rotation of the upper sprocket drives the lower sprocket to rotate through the transmission chain. The rotation of the lower sprocket drives the support shaft 315 to rotate. The rotation of the support shaft 315 drives the rotation of the second walking wheel 316. A spacing adjustment sleeve 314 sleeved outside the second walking adjustment sleeve 312 is fixedly arranged on the upper outer side of the transmission protective cover 313 close to the walking drive shaft 21. The second walking adjustment sleeve 312 can rotate freely relative to the spacing adjustment sleeve 314. Specifically, a bearing is arranged inside the spacing adjustment sleeve 314, and the second walking adjustment sleeve 312 is sleeved on the bearing of the spacing adjustment sleeve 314. The rotation of the second walking adjustment sleeve 312 relative to the spacing adjustment sleeve 314 is realized by the support of the bearing. The spacing adjustment sleeve 314 is sleeved on a fixed support sleeve 311 fixedly arranged on the front walking bracket 2. To facilitate the rotation of the second walking adjustment sleeve 312, a bearing is arranged at the end of the fixed support sleeve 17 away from the transmission protective cover 313, and the second walking adjustment sleeve 312 is sleeved in this bearing. To facilitate the movement adjustment and positioning of the spacing adjustment sleeve 314 relative to the fixed support sleeve 311, two pressing bolts are arranged on the side wall of the fixed support sleeve 311 here. The positioning of the spacing adjustment sleeve 314 is realized by pressing the spacing adjustment sleeve 314 with the pressing bolts. To realize the fixation of the fixed support sleeve 311, a support connecting rod is arranged between the two fixed support sleeves 311 here. The support connecting rod is fixedly connected with the front walking bracket, and at the same time, the support connecting rod realizes the fixed connection of the two fixed support sleeves 311. In this specific embodiment, the transmission protective cover realizes the high support of the front walking bracket 2, thereby expanding its ground clearance. At the same time, the transmission chain realizes the equal-speed transmission of the walking drive shaft 21 to the second walking wheel 316. With a reasonable diameter of the second walking wheel 316, the reasonable walking speed of the walking bracket 2 is regulated; Walking driven wheels 323 are arranged on both sides of the rear of the rear walking bracket 32. The walking driven wheels 323 can be adjusted up and down and fixed relative to the rear walking bracket 32. Specifically, two second vertical sleeves 321 distributed left and right are arranged at the rear of the rear walking bracket 32. A second adjusting rod 322 is sleeved inside the second vertical sleeve 321. The second adjusting rod 322 can move up and down inside the second vertical sleeve 321. At the same time,A pressing bolt for realizing the pressing and positioning of the second adjusting rod 322 is arranged on the side wall of the second vertical sleeve 321. The walking driven wheel 323 is fixedly arranged at the lower part of the second adjusting rod 322. By adjusting the position of the second adjusting rod 322 in the second vertical sleeve 321, the support height of the walking driven wheel 323 for the rear walking bracket 32 is adjusted.

[0029] On the basis of the above embodiment, the specific implementation manner of the mold stripping mechanism is as follows: The mold stripping mechanism further includes a first driving shaft 62, and the first driving shaft 62 is rotatably arranged on the front walking bracket 31 along the left-right direction of the front walking bracket 31. Specifically, the first driving shaft 62 is sleeved in the bearings of two bearing seats arranged on the front walking bracket 31. Two eccentric bearings 63 are arranged on the first driving shaft 62 and are distributed relatively left and right. A first vertical sleeve 64 is fixedly arranged at the lower part of the eccentric bearing 63. A first adjusting rod 65 capable of moving up and down and positioning is sleeved at the lower part of the first vertical sleeve 64. Specifically, the first adjusting rod 65 can slide up and down in the first vertical sleeve 64. A pressing bolt is arranged on the side wall of the first vertical sleeve 64. By using the pressing action of the pressing bolt on the first adjusting rod 65, the adjustment and positioning of the first adjusting rod 65 in the first vertical sleeve 64 are realized. An adjusting frame 66 is arranged at the lower part of the first adjusting rod 65. The mold stripping knife 61 is arranged on the corresponding adjusting frame 66. The rotation of the first driving shaft 62 drives the rotation of the eccentric bearing 63, and finally the up-and-down reciprocating movement of the mold stripping knife 61 is realized. The mold stripping knife 61 can slide left and right and be positioned on the corresponding adjusting frame 66. By using the left-and-right adjusting ability of the mold stripping knife 61, it is convenient to make the two mold stripping knives 61 adapt to tobacco ridges with different widths, and then the film on both sides of the tobacco ridge can be effectively separated from the soil. The specific implementation manner of the mold stripping knife 61 for realizing left-and-right adjustment and positioning is that the sleeve at the upper part of the mold stripping knife 61 is sleeved on the adjusting frame 66, and the sleeve can slide left and right relative to the adjusting frame 66. A pressing bolt is arranged on the sleeve. By using the pressing bolt to press on the adjusting frame 66, the adjustment and positioning of the mold stripping knife 61 are realized. To facilitate the mold stripping knife 61 to cut into the soil smoothly, the mold stripping knife 61 is distributed in an inclined state with the front part lower and the rear part higher. To realize the stable up-and-down reciprocating movement of the mold stripping knife 61, here, a first vertical fixing rod is arranged in front of each first vertical sleeve 64. The upper part of the first vertical fixing rod is fixedly connected to the rear walking bracket 32. A swing limiting rod 67 is hinged at the lower part of the first vertical fixing rod. The other end of the swing limiting rod 67 is hinged to the outer side wall of the corresponding first vertical sleeve 64.

[0030] On the basis of the above embodiments, the specific implementation manner of the square film picking frame 41 rotatably arranged on the rear traveling bracket 32 is as follows: The square film picking frame 41 is rotatably arranged on the rear traveling bracket 32 along the left-right direction of the rear traveling bracket 32. Specifically, the support rotating shafts at both the left and right ends of the square film picking frame 41 are sleeved in the bearings of two bearing seats arranged on the rear traveling bracket 32. A first driving gear 42 is arranged at the left end of the square film picking frame 41, a second driving gear 43 meshing with the first driving gear 42 is arranged on the rear traveling bracket 32, and a first sprocket 44 coaxial with the second driving gear 43 is arranged on one side of the second driving gear 43. The rotation of the first sprocket 44 realizes the rotation of the square film picking frame 41.

[0031] On the basis of the above embodiments, the specific implementation manner of the cylindrical film winding rack for realizing rotation setting and conical deformation on the rear traveling bracket 32 is as follows: The cylindrical film winding rack 51 includes a rotation support shaft 511. The left end of the rotation support shaft 511 is sleeved in a bearing seat of the rear traveling bracket 32. The right end of the rotation support shaft 511 is rotationally supported by two bearings 324 distributed front and rear. A worm and gear reducer 52 is fixedly arranged on the right side of the rear part of the rear traveling bracket 32. The worm and gear reducer 52 is a mature technical product in the prior art, so the structure of the worm and gear reducer 52 will not be described in detail. The power output end of the worm and gear reducer 52 and the rotation support shaft 511 are driven by a bevel gear transmission method. Specifically, a second bevel gear 522 is arranged at the power output end of the worm and gear reducer 52, and a first bevel gear 5111 meshing with the second bevel gear 522 is fixedly arranged on the rotation support shaft 511. The rotation of the second bevel gear 522 realizes the rotational drive of the rotation support shaft 511. A second sprocket 5112 is arranged at the left end of the rotation support shaft 511. A large circular plate 512 is fixedly arranged at the left end of the rotation support shaft 511. A small circular plate 513 is sleeved at the right end of the rotation support shaft 511. The small circular plate 513 can freely slide and be positioned on the rotation support shaft 511. Specifically, a sleeve is arranged on the right side of the small circular plate 513. The sleeve is sleeved on the rotation support shaft 511, and the sleeve can drive the small circular plate 513 to slide left and right on the rotation support shaft 511. A pressing bolt is arranged on the sleeve. After the pressing bolt presses against the rotation support shaft 511, the positioning of the small circular plate 513 on the rotation support shaft 511 is realized. A plurality of sets of contraction rod assemblies are arranged between the large circular plate 512 and the small circular plate 513 and are equally spaced along the circumferential direction of the rotation support shaft 511.

When it is necessary to pull out and clean the film roll wound around the outside of the multiple first support rods 514 from the outside of the first support rods 514, the small circular plate 513 can be pushed to continuously move to the left. During the continuous leftward movement of the small circular plate 513, the outer ends of the multiple first folding rods 515 will swing to the right synchronously. As the first folding rods 515 continuously swing to the right, the right ends of the multiple first support rods 514 approach and converge towards the rotational support shaft 511, thereby causing the cylindrical structure formed by the multiple first support rods 514 to become a conical structure with a larger left side and a smaller right side. When the deformation is completed, the film roll becomes loose and the friction between it and the first support rods 514 is greatly reduced, thus facilitating the smooth pulling out of the film roll from the right side, and then realizing the rapid cleaning and collection of the film roll; further, to prevent the two bearings 324 from hindering the rightward movement of the film roll during the process of pulling out the film roll, here, the two bearings 324 are arranged on a cantilever rod 325. The front end of the cantilever rod 325 is hingedly connected to a support end of the rear walking bracket 32 through a hinge 3251. The cantilever rod 325 can swing up and down relative to the rear walking bracket 32. A first swing rod 326 is hingedly arranged at the lower part of the cantilever rod 325. A second vertical fixed rod 328 adjacent to the first swing rod 326 is arranged at the lower part of the rear walking bracket 32. A second swing rod 327 is hingedly arranged at the lower part of the second vertical fixed rod 328. The other end of the first swing rod 326 is hingedly connected to the other end of the second swing rod 327. A limit block 3271 located above the first swing rod 326 is fixedly arranged at the front end of the second swing rod 327. The limit block 3271 is located behind the hinge connection between the first swing rod 326 and the second swing rod 327. When the upper side wall of the first swing rod 326 presses against the lower part of the limit block 3271, the included angle between the first swing rod 326 and the second swing rod 327 is between 140° and 170°. In this specific embodiment, the included angle between the first swing rod 326 and the second swing rod 327 is set to 160°.When the cantilever rod 325 is in a horizontal state, the limiting block 3271 is used to limit the swing of the first swing rod 326 in the direction of the second swing rod 327, so as to realize the rotational locking of the first swing rod 326 and the second swing rod 327, and then the first swing rod 326 and the second swing rod 327 are used to support the cantilever rod 325. Subsequently, the two bearings 324 realize stable support for the right end of the rotating support shaft 511. When the film roll needs to be removed, the hinge joint of the first swing rod 326 and the second swing rod 327 is pushed obliquely upward with force, so as to release the limit locking of the first swing rod 326 and the second swing rod 327. Thus, the rear end of the cantilever rod 325 can swing downward. After the cantilever rod 325 swings downward in place, there is no obstacle at the right end of the rotating support shaft 511, which is convenient for smoothly pulling out the film roll.

[0032] In this specific embodiment, the specific implementation manner of the engine for power transmission to the traveling speed reducer, the film lifting mechanism, the film picking mechanism and the film winding mechanism is as follows: The engine 1 is a gasoline engine. A first pulley 11 is arranged at the power output end of the gasoline engine. A second pulley 21 and a third pulley 22 are coaxially arranged at the power input end of the traveling speed reducer 2. A fourth pulley 621 and a fifth pulley 622 are respectively arranged in the middle and the left end of the first drive shaft 62. A sixth pulley 521 is arranged at the power input end of the worm and gear speed reducer 52. A transmission belt 101 is sleeved between the first pulley 11 and the second pulley 21, between the third pulley 22 and the fourth pulley 621, and between the fifth pulley 622 and the sixth pulley 521. A transmission chain 102 is sleeved between the first sprocket 44 and the second sprocket 5112. When the engine 1 is started, through the power transmission of each transmission belt 101, the rotation of the traveling drive shaft 21, the first drive shaft 62, the square film picking frame 41 and the rotating support shaft 511 can be realized, so as to facilitate the lifting and collection of the film 103.

[0033] The main operating steps for collecting film using the above-mentioned film peeling machine are as follows: move the entire film peeling machine to the top of one end of the chimney, and when moving the front walking bracket 31 and the rear walking bracket 32 to the top of the chimney, try to ensure that the two first walking wheels 316 and the two walking driven wheels 323 are symmetrically distributed on both sides of the chimney, and then adjust the film peeling knives 61 on the left and right sides so that the film peeling knives 61 are located on both sides of the bottom of the chimney. Specifically, the left and right positions of the film peeling knife 61 are adjusted by moving the film peeling knife 61 on the adjusting frame 66, and the film peeling knife 61 is made to correspond to the side of the film 103. The height of the film peeling knife 61 is adjusted by moving the position of the first adjusting rod 65 up and down, and the film peeling knife 61 can be made to penetrate into the soil when it is in the lowest position; pull up one end of the film 103 under the film peeling machine, and make the free end of the film 103 first come out from the top of the square film picking frame 41 The film 103 is then wound around the bottom of the cylindrical film winding frame 51 and fixed on the cylindrical film winding frame 51. When the film peeling machine moves along the smoke ridge, looking at the film peeling machine from the left side, the cylindrical film winding frame 51 rotates counterclockwise, and the square film picking frame 41 rotates clockwise. The continuous clockwise rotation of the square film picking frame 41 can realize the up and down shaking of the film 103. During the shaking process of the film 103, it is beneficial to shake off the soil blocks adhering to the upper part of the film, and then prevent the soil blocks from being clamped in the collected film roll. At the same time, in the process of the square film picking frame 41 lifting the film 103 upward, it is beneficial to realize the tension of the film 103 between the square film picking frame 41 and the cylindrical film winding frame 51, thereby facilitating the tightening of the film 103 on the cylindrical film winding frame 51, so that the cylindrical film winding frame 51 can collect more films at one time.
