DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 and Figure 6 The present invention provides an offset adjustable orchard reflective film covering machine, comprising a frame assembly 1, a stone removal mechanism 2 and a film covering mechanism 3. The stone removal mechanism 2 and the film covering mechanism 3 are both installed on the frame assembly 1, and the frame assembly 1 can move under the traction of the traction device 100. The film covering mechanism 3 is arranged at the front end of the frame assembly 1, and is used to mount the reflective film and guide the reflective film out to achieve the laying of the reflective film. The stone removal mechanism 2 is arranged at the rear end of the frame assembly 1, and is used to cover the reflective film with stones during the film covering operation, so as to fix the reflective film laid on the ground.

[0022] The frame assembly includes two frames 101 arranged opposite to each other, a front rotating shaft 102, a rear rotating shaft 103, a pair of front frame wheels 104 and a pair of rear frame wheels 105. The two frames 101 are connected by the front rotating shaft 102 and the rear rotating shaft 103. The front rotating shaft 102 is arranged at the front ends of the two frames 101 and is rotatably connected to the two frames 101. A pair of front frame wheels 104 are located at the outside of the frames 101 and are respectively fixedly connected to the two ends of the front rotating shaft 102. The rear rotating shaft 103 is arranged at the rear ends of the two frames 101 and is rotatably connected to the two frames 101. A pair of rear frame wheels 105 are located at the outside of the frames 101 and are respectively fixedly connected to the two ends of the rear rotating shaft 103. Under the traction of the traction device 100, the front frame wheel 104 drives the front rotating shaft 102 to rotate synchronously, and the rear frame wheel 105 drives the rear rotating shaft 103 to rotate synchronously.

[0023] A first gear 106 is fixedly disposed on the rear shaft 103 . The first gear 106 is coaxially disposed with the rear shaft 103 . The first gear 106 is located between the two frames 101 . The rear shaft 103 and the first gear 106 rotate synchronously with the movement of the random frame assembly 1 .

[0024] The stone ejector 201 includes a stone ejector 201 and a displacement driver 202. The stone ejector 201 is movably arranged on the frame 101 through the displacement driver 202. The stone ejector 201 is used to accommodate stones and orderly discharge the stones onto the reflective film by rotation. The displacement driver 202 is used to drive the position of the stone ejector 201 to change. A second gear 203 is provided at the bottom of the stone ejector 201. The displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is engaged with or separated from the first gear 106.

[0025] When the laminating mechanism 3 performs the laminating operation, the displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is meshed with the first gear 106. At this time, the rotation of the rear end shaft 103 is transmitted to the stone ejector 201 through the first gear 106 and the second gear 203, thereby driving the stone ejector 201 to rotate and start the stone ejection operation to achieve stone coating on the reflective film. When the laminating mechanism 3 stops the laminating operation, the displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is separated from the first gear 106. At this time, even if the rear end shaft 103 continues to rotate, its kinetic energy will not be transmitted to the stone ejector 201, and the stone ejector 201 stops rotating and stops the stone ejection operation.

[0026] It is understandable that the stone ejector 201 is arranged at a position such that the stones ejected by the ejector can be pressed onto the reflective film laid on the ground, and the specific position can be adjusted according to the width of the reflective film.

[0027] The reflective film covering machine of the present invention can achieve synchronization between film covering and stone covering on the reflective film, so that the reflective film can be immediately pressed by stones after film covering and is not easily blown away by the wind, thereby ensuring the stability of the film covering and the smoothness of the reflective film laying, improving the reflective effect of the film covering, and at the same time reducing work intensity, saving manpower, and effectively improving work efficiency.

[0028] Furthermore, the rear end rotating shaft 103 is provided with two first gears 106 along its axial direction, and the two stone ejection mechanisms 2 are symmetrically arranged along the central axis in the length direction of the frame assembly 1, and the two first gears 106 are arranged one-to-one with the two stone ejection mechanisms 2. The bottom of the two stone ejection mechanisms 2 is provided with a second gear 203, and the rotation of the rear end rotating shaft 103 is synchronously transmitted to the two stone ejectors 201 through the two first gears 106 and the two second gears 203. The two stone ejectors 201 can cover the two side edges of the reflective film with stones to fix the two side edges of the reflective film, further improving the stability of the film and the flatness of the reflective film, thereby further improving the reflective effect of the film.

[0029] See also Figures 1 to 3 The stone ejector 201 comprises a bracket 2011, a stone loading tube 2012, a stone ejector frame 2013 and a shell 2014. The shell 2014 has a receiving cavity and a stone ejector opening 20141 connected to the receiving cavity. The stone ejector opening 20141 is designed with a certain slope to buffer the impact force of falling stones and reduce the impact on the reflective film. The stone loading tube 2012 and the stone ejector frame 2013 are both sleeved in the receiving cavity of the shell 2014. The stone loading tube 2012 and the stone ejector frame 2013 are coaxially arranged. The stone ejector frame 2013 is located on one side of the stone loading tube 2012 close to the stone ejector opening 20141. One end of the stone ejector frame 2013 abuts against the bottom of the stone loading tube 2012. The other end of the stone ejector frame 2013 extends from the bottom of the shell 2014 and is fixedly connected to the second gear 203. The stone loading barrel 2012 is used for containing stones, and an oblique stone discharge pipe extending toward one side of the stone discharge rack 2013 is provided at the bottom thereof, and the stones in the stone loading barrel 2012 fall onto the stone discharge rack 2013 through the oblique stone discharge pipe.

[0030] The stone rack 2013 includes a stone rack body, connecting columns 20131 and supporting columns 20132 located on opposite sides of the stone rack body. The shape of the stone rack body matches the shape of the accommodating cavity of the shell 2014 to prevent stones from falling from the gap between the stone rack body and the inner wall of the shell 2014. The supporting columns 20132 are located beside the oblique stone-discharging pipe. The supporting columns 20132 abut against the bottom of the stone-loading tube 2012, so that there is a certain gap between the stone rack body and the bottom of the stone-loading tube 2012, and a certain activity space is reserved for the stones that fall onto the stone rack body. At the same time, the supporting columns 20132 can enable the stones in the stone-loading tube 2012 to be discharged onto the stone rack body in an orderly manner. The connecting column 20131 extends from the bottom of the housing 2014 and is fixedly connected to the second gear 203. The stone-discharging frame 2013 can rotate along its axial direction under the drive of the second gear 203, so that the stones that fall onto the stone-discharging frame body can move to the edge of the stone-discharging frame body under the centrifugal force and gravity, and finally be discharged through the stone-discharging port 20141. The stone-discharging frame body can be designed to have a certain slope so that the stones can smoothly roll to the edge of the stone-discharging frame body.

[0031] Furthermore, in order to ensure the stability between the stone rack 2013 and the stone loading tube 2012, a limiting groove can be provided at the bottom of the stone loading tube 2012 so that the end of the support column 20132 is embedded in the limiting groove.

[0032] The bracket 2011 includes a fixing ring 20111 and a support rod 20112, the fixing ring 20111 and the support rod 20112 are fixedly connected, the fixing ring 20111 is sleeved on the outer wall at the top of the housing 2014, and the support rod 20112 is rotatably connected to the frame 101 through the bracket shaft 2015. The fixing ring 20111, the housing 2014 and the stone-loading tube 2012 are assembled together by bolts and can be freely disassembled.

[0033] It should be noted that the axes of the housing 2014, the stone loading tube 2012 and the stone discharge rack 2013 are all perpendicular to the plane where the frame assembly 1 is located, so as to ensure that the stones are discharged smoothly under the action of centrifugal force and gravity. In addition, the first gear 106 and the second gear 203 are both helical gears, and the first gear 106 is coaxially arranged with the rear end shaft 103, and the axial direction of the second gear 203 is perpendicular to the axial direction of the first gear 106, so as to ensure that the first gear 106 and the second gear 203 transmit the power of the rear end shaft 103 to the stone discharge rack 2013.

[0034] The displacement driver 202 may be a hydraulic lifting cylinder, which is fixed on the frame 101, and the moving end of the hydraulic lifting cylinder is connected to the bracket 2011. The hydraulic lifting cylinder drives the bracket 2011 to rotate a certain angle around the bracket shaft 2015 through lifting motion, so that the stone ejector 201 moves around the bracket shaft 2015. The lifting hydraulic cylinder is used to drop the stone ejector 201 when stone ejection is required, so as to achieve the meshing of the second gear 203 and the first gear 106; the lifting hydraulic cylinder is also used to lift the stone ejector 201 when stone ejection is not required, so as to achieve the separation of the second gear 203 and the first gear 106.

[0035] Of course, in other embodiments, the displacement driver 202 can also be other types of structures that can drive the stone ejector 201 to change its displacement, such as a linear stepping motor, a servo motor or a pneumatic driver, etc., as long as it can drive the stone ejector 201 to move in the horizontal direction or the vertical direction, thereby realizing the engagement or separation of the second gear 203 with the first gear 106.

[0036] In one embodiment, the front rotating shaft 102 and the rear rotating shaft 103 are both retractable rotating shafts, which are rotating shafts that can be retracted along their axial direction to achieve length adjustment. For example, the retractable rotating shaft is connected by two or more shafts, and two adjacent shafts can slide toward or away from each other, thereby achieving different lengths of the rotating shaft. By adjusting the telescopic length of the front rotating shaft 102 and the rear rotating shaft 103, the width of the frame assembly 1 can be adjusted. In this way, the frame assembly 1 can be adapted to reflective films of different widths according to the requirements of different film widths.

[0037] See also Figure 1 and Figure 4 The film coating mechanism 3 includes a film guide cylinder 301, a film hanging shaft (not shown) and a rotary driver 302. The axial direction of the film guide cylinder 301 is perpendicular to the travel direction of the frame assembly 1. Both ends of the film guide cylinder 301 are fixed to the frame 101 for guiding the reflective film. The film hanging shaft is coaxially arranged with the film guide cylinder 301 and penetrates the film guide cylinder 301. The reflective film roll can be mounted on the film hanging shaft. Both ends of the film hanging shaft are rotatably connected to the frame 101. The rotary driver 302 is fixed to the frame 101, and the output shaft of the rotary driver 302 is fixedly connected to one end of the film hanging shaft. The rotary driver 302 drives the film hanging shaft to rotate, and the reflective film roll rotates synchronously with the film hanging shaft, so that the reflective film roll releases the reflective film.

[0038] The rotary driver 302 may be a rotary drive motor.

[0039] Specifically, the film guide cylinder 301 includes a cylinder body 3011 and an extension plate 3012. The extension plate 3012 extends from the outer wall of the cylinder body 3011 to the side close to the stone discharge mechanism 2. The cylinder body 3011 is provided with a film guide port 30111 extending along the axial direction of the cylinder body 3011. The reflective film roll is accommodated in the cylinder body 3011, and the reflective film is guided out from the film guide port 30111. The extension plate 3012 is provided with a film cutting groove 30121 extending along the axial direction of the cylinder body 3011, and the reflective film can be cut at the film cutting groove 30121.

[0040] In order to ensure the stability of the film guiding, the two ends of the film guiding cylinder 301 can be welded to the two frames 101, so as to prevent the film guiding port 30111 from deviating during the film guiding process.

[0041] In one embodiment, the film guide tube 301 and the film hanging shaft are both retractable structures, and the film hanging shaft is similar to the structure of the retractable front end rotating shaft 102 and the rear end rotating shaft 103 mentioned above, which will not be repeated here. The film guide tube 301 is connected by two or more sleeves, and the adjacent two sleeves can slide toward or away from each other, so as to achieve the adjustment of different lengths of the film guide tube 301. Among them, each sleeve is provided with a rectangular opening of the same size, the rectangular openings on the adjacent two sleeves are aligned, and the rectangular openings on all sleeves are combined to form a film guide opening 30111 with adjustable opening length. And, the outer wall of each sleeve extends an extension portion toward the side close to the stone discharge mechanism 2, and the adjacent two extension portions are also connected by sleeves, and all extension portions are combined to form an extension plate 3012 with adjustable length. Each extension portion is provided with a slot extending along the axial direction of the sleeve, and the slots on the adjacent two extension portions are aligned, and the slots on all extension portions are combined to form a film cutting groove 30121 with adjustable length. In this way, reflective films of different widths can be adapted by adjusting the telescopic length of the film guiding cylinder 301 and the film hanging shaft in the width direction of the frame assembly 1 .

[0042] See also Figure 1 and Figure 5 Furthermore, the reflective film covering machine also includes a film cutting mechanism 4, which is arranged between the film covering mechanism 3 and the stone discharging mechanism 2, and is used to cut the luminous film. The film cutting mechanism 4 includes a film cutting knife 401, a film cutting bracket 402 and a film cutting driver (not shown), the film cutting knife 401 is fixed on the film cutting bracket 402, the film cutting driver is fixed on the frame 101, one end of the film cutting bracket 402 is rotatably connected to the frame 101 through a rotating shaft, and the other end of the film cutting bracket 402 is fixedly connected to the output shaft of the film cutting driver. The film cutting driver is used to drive the film cutting bracket 402 and the film cutting knife 401 to rotate synchronously at a certain angle, and control the film cutting knife 401 to cut the reflective film at the film cutting groove 30121.

[0043] Among them, the film cutting knife 401 is made of steel, which can ensure the film cutting efficiency.

[0044] In one embodiment, the film cutting knife 401 is a retractable structure, and the film cutting knife 401 can be adapted to reflective films of different widths by adjusting the retractable length of the film cutting knife 401 in the width direction of the frame assembly 1. For example, the film cutting knife 401 is composed of two or more nestable triangular sleeves, and two adjacent triangular sleeves can slide toward or away from each other, thereby achieving the adjustment of different lengths of the film cutting knife 401.

[0046] In one embodiment, the traction device connecting block 5 is offsetly arranged corresponding to the frame 101 on one side, so that a certain angle of fixed-axis rotation can be achieved, which is convenient for disassembly.

[0047] In one embodiment, the connecting shaft 6 is a telescopic structure, and the connecting shaft 6 has a similar structure to the telescopic front rotating shaft 102 and the rear rotating shaft 103 described above, which will not be described in detail here.

[0050] The traction device 100 may be a tractor with an automatic navigation system. The reflective film covering machine is installed on a connecting frame behind the tractor, and the reflective film covering machine is driven by the tractor to perform the reflective film covering operation.

[0051] See also Figure 1 , Figure 6 and Figure 7 The present invention also provides a laminating method using the reflective film covering machine as described above, which specifically comprises the following steps: Step 1: The detection device 7 detects the starting coordinates and the end point coordinates, and transmits the detected starting coordinate information and the end point coordinate information to the control system 8.

[0052] Specifically, the starting coordinates are the point coordinates of the first fruit tree in a row of fruit trees, and the ending coordinates are the point coordinates of the last fruit tree in the row of fruit trees.

[0053] Step 2, when the traction device 100 reaches the starting coordinate, the control system 8 sends the coating information to the coating mechanism 3 based on the starting coordinate information, and the coating mechanism 3 starts the coating operation; at the same time, the control system 8 sends the stone removal signal to the stone removal mechanism 2, and the displacement driver 202 drives the stone removal device 201 to move so that the second gear 203 engages with the first gear 106, and the stone removal device 201 covers the stone on the reflective film.

[0054] Among them, O0 (X0, Y0, Z0) is set as the starting coordinate of a row of fruit trees for film covering operation. d (X d ,Y d ,Z d ) as the end point coordinates of the film covering operation for a row of fruit trees.

[0055] When the traction device 100 reaches the starting coordinate O0 (X0, Y0, Z0), the control system 8 transmits the coating information to the rotary driver 302, and the rotary driver 302 rotates to drive the film hanging shaft to rotate, so that the reflective film is led out along the film guide port of the film guide cylinder 301. At the same time, the control system 8 transmits the stone ejection signal to the displacement driver 202, and the displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is meshed with the first gear 106, so that the stone ejector 201 covers the reflective film with stones.

[0056] In one embodiment, the displacement driver 202 is a lifting hydraulic cylinder, and a hydraulic pump 9 is provided on the traction device 100. The control system 8 transmits the stone removal signal to the hydraulic pump 9, and the hydraulic pump 9 reduces the hydraulic oil delivered to the lifting hydraulic cylinder. The lifting hydraulic cylinder descends to cause the stone ejector 201 to fall, so that the second gear 203 engages with the first gear 106.

[0057] Step 3, when the traction device 100 reaches the end point coordinates, the control system 8 sends the stop coating information to the coating mechanism 3 based on the end point coordinate information, and the coating mechanism 3 stops the coating operation; at the same time, the control system 8 sends the stop stone removal signal to the stone removal mechanism 2, and the displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is separated from the first gear 106, and the stone ejector 201 stops covering the stone.

[0058] When the traction device 100 completes the coverage of a row of reflective film and reaches the end coordinate O d (X d ,Y d ,Zd ), the control system 8 transmits the stop coating information to the rotary driver 302, the rotary driver 302 stops rotating, and the reflective film stops being exported. At the same time, the control system 8 sends the stop stone ejection signal to the displacement driver 202, the displacement driver 202 drives the stone ejector 201 to move so that the second gear 203 is separated from the first gear 106, and the stone ejector 201 stops coating the stone.

[0059] In one embodiment, the control system 8 can transmit the stone ejection signal to the hydraulic pump 9, and the hydraulic pump 9 increases the hydraulic oil to be delivered to the lifting hydraulic cylinder. The lifting hydraulic cylinder rises to lift the stone ejector 201, thereby separating the second gear 203 from the first gear 106.

[0060] In one embodiment, the reflective film covering machine further includes a film cutting mechanism 4, which is connected to a control system 8, and includes a film cutting knife 401, a film cutting bracket 402 and a film cutting driver. For details, please refer to the above description, which will not be repeated here. Therefore, in the above step 3, after stopping the film covering operation and the stone covering operation, the following steps are also included: The control system 8 sends the film cutting signal to the film cutting driver, and the film cutting driver drives the film cutting knife 401 to reciprocate to complete one film cutting.

[0061] After completing the reflective film covering operation on one row of fruit trees, the traction device 100 tows the reflective film covering machine to the next row of fruit trees, the detection device 7 detects the next row of fruit trees, and then performs the reflective film covering operation on the next row of fruit trees.

[0062] During the whole working process, the fruit trees are detected by the detection device 7, and the film is covered and cut after the fruit trees are detected, which can reduce unnecessary reflective film covering and avoid waste of reflective film.

[0063] The offset adjustable orchard reflective film covering machine and film covering method of the present invention is driven by the traction device 100 to move forward. When reaching the starting coordinate, driven by the rotary driver 302, the film hanging shaft rotates so that the reflective film is guided along the film guide tube 301 and then laid flat on the ground. As the traction device 100 moves forward, the rear end shaft 103 rotates to drive the first gear 106 to rotate, and the second gear 203 meshing with the first gear 106 rotates to drive the stone discharge frame 2013 to rotate. The stones in the stone loading tube 2012 enter the stone discharge frame 2013, roll to the edge of the stone discharge frame 2013 under the action of centrifugal force and its own gravity, and then fall onto the reflective film through the stone discharge port 20141 on the shell 2014, achieving the film pressing effect. When the reflective film covering operation of a row of fruit trees is completed, the hydraulic lifting cylinder is controlled to lift the stone discharger 201, and the stones stop rolling down. The whole process is completed automatically with the operation of the traction device and the reflective film laminating machine. There is no need for manual stone covering and film cutting. The labor intensity of the staff is low and the work efficiency is high. The staff can complete the laminating work with the assistance of the laminating machine, which is very suitable for orchard environment operations. In addition, the laid reflective film is flat and straight, and it is not easy to be blown away by the wind after the laminating is completed, and the reflective effect is better.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
