Description

Technical Field

[0001] The present invention relates to the technical field of ground film recovery, and more particularly to a longitudinal spike-tooth belt type surface ground film recovery machine. Background Art

[0061] See also Figures 1 to 11 In an embodiment of the present invention, a longitudinal spike-tooth belt type surface film recycling machine comprises:

[0062] Equipment frame 1, driven by a tractor;

[0063] The film-forming device 2 is fixed on the equipment frame 1;

[0064] The impurity removal device 3 is fixed on one side of the film forming device 2;

[0065] The collecting device 4 is fixed on the side of the film forming device 2 away from the impurity removing device 3;

[0066] The crushing device 5 is fixed on the side of the impurity removing device 3 away from the film forming device 2 .

[0067] In this embodiment, the film forming device 2 includes:

[0068] The driving roller 21 is rotatably arranged at the lower part of the equipment frame 1 and adjacent to the ground surface;

[0069] The driven roller assembly 22 is rotatably arranged just above the driving roller 21;

[0070] The regulating roller assembly 23 is rotatably arranged above the driven roller assembly 22, corresponds to the collecting device 4, and has the same structure as the driven roller assembly 22;

[0071] A fixed adjustment assembly 24 is fixed in the adjustment roller assembly 23;

[0072] The first comb assembly 25 is sleeved on the driving roller 21, the driven roller assembly 22 and the adjusting roller assembly 23;

[0073] The second comb tooth assembly 26 is spaced apart from the first comb tooth assembly 25 and has the same structure;

[0074] The recycling comb plate 27 is arranged below the comb assembly and corresponds to the comb assembly.

[0075] That is to say, while the tractor drives the equipment frame 1 to move, the driving roller 21 and the adjusting roller assembly 23 rotate, and under the action of the comb tooth assembly, the driven roller assembly 22 follows the rotation, and at the same time drives the first comb tooth assembly 25 and the second comb tooth assembly 26 to rotate on the driving roller 21, the driven roller assembly 22 and the adjusting roller assembly 23, to split and pick up the ground film, and the combined design of the secondary comb tooth assembly and multiple rollers can better adapt to ground films of different thicknesses and states, as well as different crop terrain conditions. The double rollers of the driven roller assembly 22 and the adjusting roller assembly 23 effectively reduce the force on the single-layer roller, reduce the occurrence of problems such as insufficient short-axis power caused by local overload, and reduce maintenance costs. The recovery comb tooth plate 27 collects smaller pieces of ground film that fall during the stripping process and re-hangs them on the comb tooth assembly by the recovery comb tooth plate 27, re-enters the recycling process, and improves the ground film recovery rate.

[0076] In this embodiment, the driven roller assembly 22 is provided with a rotating shaft 223, and multiple groups of first roller groups 221 and second roller groups 222 fixed on the rotating shaft 223 in sequence, and the roller diameter of the second roller group 222 is smaller than the roller diameter of the first roller group 221.

[0077] That is to say, the driven roller assembly 22 and the adjusting roller assembly 23 are provided with corresponding first roller groups 221 and second roller groups 222. The first roller group 221 corresponds to the first comb tooth assembly 25, and the second roller assembly 222 corresponds to the second comb tooth assembly 26. Since the roller diameter of the second roller group 222 is smaller than the roller diameter of the first roller group 221, the first comb tooth assembly 25 and the second comb tooth assembly 26 are staggered. The first comb tooth assembly 25 is responsible for the initial film picking, and the second comb tooth assembly 26 performs secondary combing to form a stepped film-lifting effect.

[0078] In this embodiment, the fixed adjustment component 24 includes:

[0079] The fixed shaft 241 passes through the center of the rotating shaft 223 in the adjusting roller assembly 23 and is fixedly connected to the equipment frame 1;

[0080] Multiple special-shaped slide rails 242 are linearly distributed along the fixed axis 241 and correspond to the first roller group 221 and the second roller group 222 respectively. The special-shaped slide rails 242 corresponding to the second roller group 222 are smaller in size than the special-shaped slide rails 242 corresponding to the first roller group 221.

[0081] The driving shafts 243 are provided in a plurality in an annular distribution and are slidably mounted on the special-shaped slide rails 242 and are slidably connected to the corresponding roller assemblies;

[0082] The return spring 244 is sleeved on the driving shaft 243 and is located between the special-shaped slide rail 242 and the inner wall of the roller assembly.

[0083] In this embodiment, the special-shaped slide rail 242 is composed of a section of convex slide rail and a section of concave slide rail, and the position corresponding to the convex slide rail is the contact portion between the comb assembly and the roller assembly.

[0084] That is to say, when the rotating shaft 223 in the adjusting roller assembly 23 drives the first roller group 221 and the second roller group 222 to rotate, it also drives multiple driving shafts 243 to slide on the special-shaped slide rail 242. When the driving shaft 243 moves to the contact position between the comb tooth assembly and the roller assembly, the driving shaft 243 slides to the position of the convex slide rail, and then the driving shaft 243 is pushed to the outside of the roller group under the action of the convex slide rail, compressing the reset spring 244. During the continuous rotation process, the driving shaft 243 moves to the position of the concave slide rail, and the concave slide rail pulls the driving shaft 243 back. At the same time, the reset spring 244 is reset, and the auxiliary driving shaft 243 is retracted to the inside of the roller group, and the cycle is repeated.

[0085] In this embodiment, the first comb assembly 25 includes a rigid conveyor belt 251 sleeved on the first roller assembly 221 , and a plurality of comb mechanisms 252 are provided on the rigid conveyor belt 251 , and the comb mechanisms 252 correspond to the fixed adjustment assembly 24 .

[0086] That is, when the rigid conveyor belt 251 drives the comb mechanism 252 to move onto the roller assembly in the adjusting roller assembly 23, the comb mechanism 252 corresponds to the driving shaft 243 inside the roller assembly.

[0087] In this embodiment, the comb mechanism 252 includes:

[0088] Comb member 2521, fixed on the rigid conveyor belt 251;

[0089] A pushing channel 2522 is provided at the inner center of the comb tooth member 2521 , a moving member 2524 is provided at the bottom of the pushing channel 2522 , and a compression spring 2523 is provided inside the pushing channel 2522 ;

[0090] The cleaning plates 2525 are fixed to both sides of the moving member 2524 through connecting members and are slidably connected to the sides of the comb member 2521 .

[0091] That is to say, when the comb mechanism 252 rotates to the roller group in the adjusting roller assembly 23, the driving shaft 243 inside the roller group is connected to the moving part 2524 at the bottom of the comb mechanism 252, and then the driving shaft 243 continues to move on the outer convex slide rail, and the driving shaft 243 extends and moves to the pushing channel 2522 inside the comb member 2521 through the moving part 2524, compressing the compression spring 2523, and at the same time driving the cleaning plates 2525 on both sides to move through the connecting part, cleaning the ground film on the comb member 2521 and transporting it to the collecting device 4 to prevent some ground film fragments from being entangled on the comb member 2521 and affecting the subsequent To improve the efficiency of ground film cleaning, when the pushing shaft 243 slides on the inward concave slide rail, the pushing shaft 243 is gradually retracted, and under the rebound action of the compression spring 2523, the moving part 2524 and the cleaning plate 2525 are driven to move and reset, and the pushing shaft 243 is separated from the comb tooth part 2521. At the same time, the comb tooth part 2521 and the rigid conveyor belt 251 are separated from the roller group on the adjusting roller assembly 23. It should be noted that the first roller group 221 and the second roller group 222 are internally provided with corresponding fixed adjustment components 24, and the corresponding first comb tooth components 25 and second comb tooth components 26 are adjusted to remove the ground film fragments on the comb tooth part 2521.

[0092] In this embodiment, the impurity removal device 3 includes:

[0093] The transmission mechanism 31 is fixed on the equipment frame 1;

[0094] The conveyor belt 32 is sleeved on the conveying mechanism 31, and the conveying direction is perpendicular to the moving direction of the equipment frame 1;

[0095] The clamping posts 33 are distributed in multiple groups along the conveying direction, with each group having multiple clamping posts 33 , and are fixed on the conveyor belt 32 .

[0096] That is to say, after the impurities and ground film are picked up by the comb mechanism 252, the impurities are mixed with the ground film. At this time, due to the different properties of the ground film, impurity clods and straw materials, the rigid conveyor belt 251 has a certain speed. The clods and other impurities are thrown out from the comb member 2521 due to the action of centrifugal inertia. By controlling the speed of the rigid conveyor belt 251, the impurities fall into the conveyor belt 32, and the clods are separated and sent out of the equipment by the conveyor belt 32 to return to the field. Some clods are connected to large pieces of ground film, and the clods cannot be discharged smoothly on the conveyor belt 32. The clods are clamped by the clamping column 33, and the clods are forced to be discharged with the conveyor belt 32 and separated from the ground film at the same time. The clamping column 33 is an inverted flat head bolt.

[0097] In this embodiment, the collecting device 4 includes:

[0098] The collecting and transferring channel 41 is fixed on the equipment frame 1 and corresponds to the driven roller assembly 22;

[0099] The separation groove 42 is fixed at one end of the collecting and transferring channel 41 adjacent to the driven roller assembly 22 and corresponds to the first comb tooth assembly 25 and the second comb tooth assembly 26 respectively;

[0100] The packaging chamber 43 is fixed on the equipment frame 1 and is located below the collecting and transferring channel 41 .

[0101] That is to say, when the adjusting roller assembly 23 drives the comb tooth assembly to rotate to the collection and transfer channel 41, the comb tooth part 2521 corresponds to the corresponding separation groove 42, and the ground film fragments on the comb tooth part 2521 are separated through the separation groove 42. At the same time, the cleaning plate 2525 moves on both sides of the comb tooth part 2521 to assist in cleaning the ground film fragments to prevent the ground film fragments from accumulating in the separation groove 42 and affecting subsequent cleaning. The width of the separation groove 42 is greater than the sum of the widths of the comb tooth part 2521 and the cleaning plates 2525 on both sides to ensure that the comb tooth part 2521 passes through the separation groove 42 smoothly and completely cleans the ground film fragments. The cleaned ground film fragments are transported to the packaging chamber 43 for unified recycling and processing.

[0102] In this embodiment, the crushing device 5 includes:

[0103] The cutting roller 51 is rotatably arranged at the front end of the moving direction of the equipment frame 1;

[0104] A cutting comb blade 52 is fixed on the cutting roller 51;

[0105] The fixed blade 53 is fixed to the outer shell of the crushing device 5 and corresponds to the cutting comb blade 52;

[0106] The conveying auger mechanism 54 is rotatably arranged above the cutting roller 51, and the spirals at both ends are opposite.

[0107] That is to say, driven by the cutting roller 51, the fixed blade 53 and the cutting comb blade 52 cooperate with each other to cut and crush the straw multiple times to ensure that the straw is fully crushed. The separate bidirectional cutting comb blade 52 and the fixed blade 53 can fix and cut the straw more efficiently, and the conveying auger mechanism 54 is used to evenly output the crushed straw from both sides to the field. The design of the auger can ensure that the straw will not be blocked during the transportation process and can be evenly distributed on the soil surface, thereby increasing the decomposition speed of the straw and improving the waste utilization rate.

[0108] During the specific implementation, first, while the tractor drives the equipment frame 1 to move, the driving roller 21 and the adjusting roller assembly 23 rotate. Under the action of the comb tooth assembly, the driven roller assembly 22 follows the rotation, and at the same time drives the first comb tooth assembly 25 and the second comb tooth assembly 26 to rotate on the driving roller 21, the driven roller assembly 22 and the adjusting roller assembly 23, and the ground film is divided and picked up by the comb tooth mechanism 252. Then, after the impurities and the ground film are picked up by the comb tooth mechanism 252, the impurities are mixed with the ground film. At this time, due to the different properties of the ground film, impurity clods and straw materials, the rigid conveyor belt 251 has a certain speed, and impurities such as clods are thrown out from the comb tooth member 2521 due to the action of centrifugal inertia. By controlling the rigid conveyor The speed of belt 251 makes impurities fall into conveyor belt 32, so that soil blocks are separated and sent out of the equipment and returned to the field by conveyor belt 32. When the comb mechanism 252 rotates to the roller group in the adjusting roller assembly 23, the driving shaft 243 inside the roller group is connected with the moving part 2524 at the bottom of the comb mechanism 252, and then the driving shaft 243 continues to move on the convex slide rail. When the comb member 2521 rotates to the collection and transfer channel 41, the comb member 2521 corresponds to the corresponding separation groove 42, and the ground film fragments on the comb member 2521 are separated by the separation groove 42. At the same time, the driving shaft 243 extends out under the action of the convex track and pushes the channel 25 into the comb member 2521 through the moving part 2524. 22 moves, compresses the compression spring 2523, and at the same time drives the cleaning plates 2525 on both sides to move through the connecting parts to assist in cleaning the ground film fragments to prevent the ground film fragments from accumulating in the separation groove 42 and affecting subsequent cleaning. The width of the separation groove 42 is greater than the sum of the widths of the comb teeth 2521 and the cleaning plates 2525 on both sides to ensure that the comb teeth 2521 can pass through the separation groove 42 smoothly and completely clean the ground film fragments. The cleaned ground film fragments are transported to the packaging chamber 43 for unified recycling. When the rigid conveyor belt 251 drives the comb teeth 2521 to be about to leave the roller group, the push shaft 243 slides on the inward concave slide rail, and the push shaft 243 is gradually retracted, and under the rebound action of the compression spring 2523 Under the use, the moving part 2524 and the cleaning plate 2525 are moved and reset, and the shaft 243 is pushed out of the comb tooth part 2521. When the comb tooth assembly recycles and demolds the ground film, the recovery comb tooth plate 27 collects the smaller pieces of ground film that fall during the demolding process and re-hangs them on the comb tooth assembly by the recovery comb tooth plate 27, and re-enters the recycling process to improve the ground film recovery rate. In addition, a crushing device 5 is also provided, which drives the fixed blade 53 and the cutting comb blade 52 to cooperate with each other through the cutting roller 51 to cut and crush the straw multiple times to ensure that the straw is fully crushed. The conveying auger mechanism 54 is used to output the crushed straw evenly from both sides to the field, effectively improving the decomposition speed of the straw and improving the waste utilization rate.
