Description

Technical Field

[0001] The invention relates to the technical field of agricultural film mulching machines, and in particular to an agricultural film mulching machine used for agricultural mechanization. Background Art

[0002] The film covering machine is generally used to cover the winter crops with film, which can keep the crops warm and reduce water evaporation, thereby improving the survival rate of the crops. A Chinese patent (publication number: CN103843635B) discloses a ground film covering machine, including a furrowing plow, a ground film release roller, and a rocker arm connector connected to the power system traction, and a film covering assembly; the film covering assembly includes a pair of ground film release roller assemblies, a film pressing shaft roller assembly, a film rolling wheel group, and a soil covering rolling wheel group; a bracket is arranged behind the rocker arm connector, and a supporting wheel is arranged before and below the bracket; the furrowing plow is arranged in front of the front supporting wheel, and the front part of the left and right cross beams of the bracket is an arc rod structure, and the highest part of the arc rod is connected to the ground film release roller assembly, and the left and right cross beams are arranged near the arc rod. The film pressing shaft roller assembly is arranged, and the film rolling wheel group and the soil covering rolling wheel group are arranged in sequence behind the film pressing shaft roller assembly; the front cross beam of the bracket is provided with a sprayer placement bracket.

[0003] However, the existing laminating machines have some disadvantages when used, such as:

[0004] Most of the existing laminating machines cover the end of the plastic film on the film roll with soil, then move the film roll to automatically stretch the plastic film, and then use the laminating equipment to press the covering soil to achieve laminating. However, since the laminating machine cannot achieve a uniform travel speed, the stretching of the plastic film is prone to unevenness, which can easily cause the plastic film to become loose when laid. The loose plastic film is easily blown away by the wind and cannot protect the crops. Therefore, a laminating machine that can tension the film is needed to ensure that the plastic film can be tensioned during laminating to prevent the plastic film from being easily blown away by the wind. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose an agricultural mulching machine for agricultural mechanization to solve the problem that most of the existing mulching machines cover the end of the plastic film on the film roll with soil, move the film roll to automatically stretch the plastic film, and then use the mulching equipment to press the covering soil to achieve mulching. However, since the traveling speed of the mulching machine cannot be uniform, the stretching of the plastic film is prone to unevenness, which can easily cause the plastic film to be loose when laid. The loose plastic film is easily blown away by the wind and cannot protect the crops. Therefore, a mulching machine that can tension the film is needed to ensure that the plastic film can be tensioned during mulching to avoid the problem that the plastic film is easily blown away by the wind.

[0006] Based on the above-mentioned purpose, the present invention provides an agricultural mulching machine for agricultural mechanization, comprising a film covering mobile bracket and a pressing wheel installed at the bottom of the film covering mobile bracket, the pressing wheel is used to assist in film covering, and soil covering plates are centrally and obliquely arranged at the bottom of both sides of the film covering mobile bracket, and the soil covering plates are used to gather the soil on both sides inward, and a traction frame is rotatably installed at the bottom of one end of the film covering mobile bracket, and a pull ring is fixedly connected to the end of the traction frame away from the film covering mobile bracket, and a film roller is rotatably installed inside the end of the traction frame close to the pull ring, and a soil covering film is wound on the film roller, and tensioning columns are respectively fixedly arranged on the upper part of both sides of the traction frame, and a tensioning roller is sleeved on the top of the tensioning column, and the tensioning roller is used to tension the soil covering film.

[0008] Furthermore, a limit plate is fixed on the top of the tensioning column, and a tensioning sleeve is provided on the sliding sleeve of the tensioning column. The limit plate is used to prevent the tensioning sleeve from sliding off the tensioning column. A tensioning spring is provided on the tensioning column, and the tensioning spring is arranged between the tensioning sleeve and the traction frame. The tensioning spring is used to push the tensioning sleeve away from the traction frame, and the tensioning roller is rotatably installed between the two tensioning sleeves.

[0009] Furthermore, a first guide roller is rotatably installed inside the traction frame at one side of the tensioning column, a second guide roller is rotatably installed inside the traction frame at the other side of the tensioning column, and a third guide roller is rotatably installed inside the traction frame at one end close to the film covering movable bracket. The first guide roller, the second guide roller and the third guide roller are all used to guide the extension direction of the soil covering film, and the soil covering film passes through the first guide roller, the tensioning roller, the second guide roller and the third guide roller in sequence.

[0010] Furthermore, a first positioning roller is rotatably installed inside the sliding positioning sleeve, and the first positioning roller is used to press and position the soil covering film.

[0028] An agricultural mulching machine for agricultural mechanization, comprising a mulching mobile bracket 101 and a pressing wheel 102 installed at the bottom of the mulching mobile bracket 101, the pressing wheel 102 is used to assist in mulching, and soil covering plates 103 are centrally and obliquely arranged at the bottom of both sides of the mulching mobile bracket 101, the soil covering plates 103 are used to gather the soil on both sides inward, a traction frame 104 is rotatably installed at the bottom of one end of the mulching mobile bracket 101, a pull ring 109 is fixedly connected to the end of the traction frame 104 away from the mulching mobile bracket 101, a film roller 105 is rotatably installed inside the end of the traction frame 104 close to the pull ring 109, a soil covering film 106 is wound on the film roller 105, and tensioning columns 107 are respectively fixedly arranged on the upper part of both sides of the traction frame 104, and a tensioning roller 108 is sleeved on the top of the tensioning column 107, and the tensioning roller 108 is used to tension the soil covering film 106;

[0029] Among them, the bearing used for the rotational connection between the film roll 105 and the traction frame 104 is a damping bearing, that is, there is a certain resistance when the film roll 105 rotates relative to the traction frame 104. The resistance can enable the film roll 105 to stop the sudden rotation in time under the condition of uneven rotation. For example, when the film covering mobile bracket 101 stops suddenly after moving quickly, the film roll 105 stops suddenly after being pulled by the covering soil film 106 to rotate quickly. If the film roll 105 uses a general bearing, then in this case, the film roll 105 will continue to rotate after the film covering mobile bracket 101 stops due to inertia, which will cause too much covering soil film 106 to fall off from the film roll 105, and it is easy to make the laid film loose.

[0030] The traction frame 104 is provided with a pull ring 109, and the user can pull the film covering mobile bracket 101 through the pull ring 109, and the film covering work is performed by the manual driving device. For farmers who plant small areas, the equipment involves less electronic control, is not easy to damage, is easy to maintain, and is convenient to use;

[0031] The present invention arranges a tensioning column 107 above the traction frame 104, and installs a tensioning roller 108 on the tensioning column 107 through a tensioning sleeve 302, and then uses the elastic force of the tensioning spring 303 to push the tensioning roller 108 upward. When the soil covering film 106 is stretched, the tensioning roller 108 is pressed downward. When the moving speed of the film covering mobile bracket 101 changes, causing the soil covering film 106 to stretch faster and become loose, the tensioning roller 108 can be lifted up in time to tension the film, thereby preventing the laid film from becoming loose and easily blown away by the wind.

[0032] Furthermore, mounting rods 201 are vertically fixed at the centers of both sides of the film-covering mobile bracket 101, and sliding positioning sleeves 202 are slidably installed on the mounting rods 201. The covering plate 103 is fixedly connected to the sliding positioning sleeves 202, and the covering plate 103 is slidably installed on the mounting rods 201 through the sliding positioning sleeves 202. The sliding positioning sleeves 202 are positioned on the mounting rods 201 by bolts, and the covering plate 103 is deflected and tilted by the sliding positioning sleeves 202.

[0033] Among them, since the covering plate 103 is rotatably mounted on the mounting rod 201 by the sliding positioning sleeve 202, the angle of the covering plate 103 can be changed by rotating the sliding positioning sleeve 202, and the height of the covering plate 103 can also be changed by changing the height of the sliding positioning sleeve 202 on the mounting rod 201. After the height and angle of the covering plate 103 are positioned, the sliding positioning sleeve 202 can be fixed to the mounting rod 201 by bolts to facilitate the adjustment and positioning of the covering plate 103.

[0034] Furthermore, a limit plate 301 is fixed on the top of the tensioning column 107, a tensioning sleeve 302 is slidably sleeved on the tensioning column 107, the limit plate 301 is used to prevent the tensioning sleeve 302 from sliding off the tensioning column 107, a tensioning spring 303 is sleeved on the tensioning column 107, the tensioning spring 303 is arranged between the tensioning sleeve 302 and the traction frame 104, the tensioning spring 303 is used to push the tensioning sleeve 302 away from the traction frame 104, and the tensioning roller 108 is rotatably installed between the two tensioning sleeves 302;

[0035] Among them, the diameter of the limit plate 301 is the same as the outer diameter of the tensioning sleeve 302, so that the limit plate 301 can block the tensioning sleeve 302, effectively preventing the tensioning sleeve 302 from sliding off the tensioning column 107, and at the same time using the tensioning spring 303 to push the tensioning sleeve 302 as far as possible toward the limit plate 301, so as to achieve tensioning of the covering film 106 on the tensioning roller 108.

[0036] Furthermore, a first guide roller 401 is rotatably installed inside the traction frame 104 at one side of the tensioning column 107, a second guide roller 402 is rotatably installed inside the traction frame 104 at the other side of the tensioning column 107, and a third guide roller 403 is rotatably installed inside the traction frame 104 at one end close to the film covering mobile bracket 101. The first guide roller 401, the second guide roller 402 and the third guide roller 403 are all used to guide the extension direction of the soil covering film 106, and the soil covering film 106 passes through the first guide roller 401, the tensioning roller 108, the second guide roller 402 and the third guide roller 403 in sequence;

[0037] Among them, the surfaces of the first guide roller 401, the second guide roller 402 and the third guide roller 403 are all provided with rubber sleeves for increasing friction, so that the first guide roller 401, the second guide roller 402 and the third guide roller 403 have a better driving and guiding effect on the covering film 106.

[0038] Furthermore, a first positioning roller 203 is rotatably installed inside the sliding positioning sleeve 202, and the first positioning roller 203 is used to press and position the soil covering film 106. A second positioning roller 404 is rotatably installed on the bottom inner wall of the film covering mobile bracket 101 close to the traction frame 104, and the second positioning roller 404 is used to press and position the soil covering film 106. The first positioning roller 203 and the second positioning roller 404 are arranged on the same horizontal plane;

[0039] The first positioning roller 203 and the second positioning roller 404 are used to position the laid soil covering film 106 to prevent the soil covering film 106 from warping and bulging during the soil covering process.

[0040] Furthermore, a water tank 501 is fixedly installed on the top of the film-covering mobile bracket 101, and the water tank 501 is used to increase the counterweight of the film-covering mobile bracket 101. A water pipe 502 is installed through the bottom of the side of the water tank 501, and the other end of the water pipe 502 is arranged below the traction frame 104. The water pipe 502 located below the traction frame 104 is arranged corresponding to the tensioning column 107. Nozzles 503 are evenly installed on the water pipe 502 located below the traction frame 104, and the nozzles 503 are arranged below the soil-covering film 106; a water pump 600 is installed at the connection between the water tank 501 and the water pipe 502, and the water pump 600 is used to pump water in the water tank 501 to the nozzle 503 through the water pipe 502;

[0041] The water tank 501 can provide a counterweight effect for the film-covered mobile bracket 101. Since a soil covering plate 103 is provided on the side of the film-covered mobile bracket 101, the soil covering plate 103 needs to be inserted into the soil to gather the soil inward. If the film-covered mobile bracket 101 is light in weight, the effect of inserting the soil covering plate 103 into the soil to gather the soil cannot be achieved.

[0042] Among them, when covering the film, the water in the water tank 501 can be sprayed onto the soil at the bottom of the covering film 106 through the water pump 600. When covering the film, the covering film 106 can be better adsorbed and adhered after contacting the moist soil, thereby avoiding the situation where the covering film 106 curls up during the covering process. At the same time, the sprayed water can also moisten the soil and replenish moisture for crops. More preferably, pesticides can be added to the water tank 501 to achieve simultaneous covering and pesticide application.

[0043] In summary, when in use, first add enough water or pesticide into the water tank 501 to add enough counterweight to the film covering mobile bracket 101, then move the device to the area where film covering is required, pull the soil covering film 106 out from the film roll 105 and pass it through the first guide roller 401, the tensioning roller 108, the second guide roller 402 and the third guide roller 403 in sequence, and place the soil covering film 106 under the first positioning pressure roller 203 and the second positioning pressure roller 404, then use the pull ring 109 on the traction frame 104 to pull the device. Since the end of the soil covering film 106 is pressed by the soil, the device moves forward. During the process, the soil covering film 106 will be pulled out from the film roller 105. When the device is in the process of acceleration, the pressure of the soil covering film 106 on the tensioning roller 108 increases, so that the tensioning spring 303 is compressed. When the device is in the process of deceleration, the bearing of the film roller 105 has damping, so that the soil covering film 106 will not be pulled out too much. At the same time, the extension of the tensioning spring 303 will further tension the soil covering film 106, which can ensure that the soil covering film 106 of the device is always in a tensioned state during the non-uniform speed movement, avoiding the situation of being blown away by the wind due to the loose film.

[0044] The present invention arranges a tensioning column 107 above the traction frame 104, and installs a tensioning roller 108 on the tensioning column 107 through a tensioning sleeve 302, and then uses the elastic force of the tensioning spring 303 to push the tensioning roller 108 upward. When the soil covering film 106 is stretched, the tensioning roller 108 is pressed downward. When the moving speed of the film covering mobile bracket 101 changes, causing the soil covering film 106 to stretch faster and become loose, the tensioning roller 108 can be lifted up in time to tension the film, thereby preventing the laid film from becoming loose and easily blown away by the wind.
