DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] Referring to Figure 1 and Figure 6 , the present application provides a bias-adjustable orchard reflective film covering mechanical, which comprises a rack assembly 1, a stone discharging mechanism 2 and a film covering mechanism 3. The stone discharging mechanism 2 and the film covering mechanism 3 are both installed on the rack assembly 1, and the rack 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 rack assembly 1, used for hanging and guiding the reflective film to realize the laying of the reflective film. The stone discharging mechanism 2 is arranged at the rear end of the rack assembly 1, used for covering stones on the reflective film during the film covering operation to fix the reflective film laid on the ground.

[0038] The rack assembly comprises two racks 101 arranged oppositely, a front end rotating shaft 102, a rear end rotating shaft 103, a pair of front end rack wheels 104 and a pair of rear end rack wheels 105. The two racks 101 are connected by the front end rotating shaft 102 and the rear end rotating shaft 103. The front end rotating shaft 102 penetrates the front ends of the two racks 101 and is rotationally connected with the two racks 101. The pair of front end rack wheels 104 are located on the outer sides of the racks 101 and are fixedly connected with the two ends of the front end rotating shaft 102 respectively. The rear end rotating shaft 103 penetrates the rear ends of the two racks 101 and is rotationally connected with the two racks 101. The pair of rear end rack wheels 105 are located on the outer sides of the racks 101 and are fixedly connected with the two ends of the rear end rotating shaft 103 respectively. Under the traction of the traction device 100, the front end rack wheels 104 drive the front end rotating shaft 102 to rotate synchronously, and the rear end rack wheels 105 drive the rear end rotating shaft 103 to rotate synchronously.

[0039] The first gear 106 is fixedly arranged on the rear end rotating shaft 103 and coaxially arranged with the rear end rotating shaft 103. The first gear 106 is located between the two racks 101. The rear end rotating shaft 103 and the first gear 106 rotate synchronously with the rack assembly 1.

[0040] The stone discharging mechanism 2 comprises a stone discharger 201 and a displacement driver 202. The stone discharger 201 is movably arranged on the rack 101 by the displacement driver 202. The stone discharger 201 is used for accommodating stones and orderly discharging the stones onto the reflective film by rotating. The displacement driver 202 is used for driving the position of the stone discharger 201 to change. The bottom of the stone discharger 201 is provided with a second gear 203. The displacement driver 202 drives the stone discharger 201 to move so as to make the second gear 203 engage with or disengage from the first gear 106.

[0041] When the film covering mechanism 3 performs the film covering operation, the displacement driver 202 drives the stone discharger 201 to move so as to make the second gear 203 engage with the first gear 106. At this time, the rotation of the rear end rotating shaft 103 is transmitted to the stone discharger 201 through the first gear 106 and the second gear 203, thereby driving the stone discharger 201 to rotate and starting the stone discharging operation, so as to realize the stone covering on the reflective film. When the film covering mechanism 3 stops the film covering operation, the displacement driver 202 drives the stone discharger 201 to move so as to make the second gear 203 disengage from the first gear 106. At this time, even if the rear end rotating shaft 103 continues to rotate, the kinetic energy of the rear end rotating shaft 103 will not be transmitted to the stone discharger 201. The stone discharger 201 stops rotating and stops the stone discharging operation.

[0042] It can be understood that the arrangement position of the stone discharger 201 needs to meet the requirement that the discharged stones can be attached and pressed on the reflective film laid on the ground. The specific position can be adjusted according to the width of the reflective film.

[0043] The application has the advantages that the synchronous application of the film and the stone on the film can make the film be pressed by the stone immediately after the film is applied, so that the film is not easily blown away by the wind, the stability of the film and the flatness of the film laying are ensured, the film reflecting effect is improved, the working strength is reduced, the manpower is saved, and the working efficiency is improved.

[0044] Further, the rear end rotating shaft 103 is provided with two first gears 106 along the axial direction thereof, the two stone discharging 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 in one-to-one correspondence with the two stone discharging mechanisms 2. The bottom of each of the two stone discharging 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 dischargers 201 through the two first gears 106 and the two second gears 203, so that the two stone dischargers 201 can discharge the stones on the two side edges of the film, so as to fix the two side edges of the film, and further improve the stability of the film and the flatness of the film laying, thereby further improving the film reflecting effect.

[0045] Referring to Figures 1 to 3 The stone discharger 201 comprises a support 2011, a stone loading cylinder 2012, a stone discharging frame 2013 and a shell 2014. The shell 2014 has a containing cavity and a stone discharging opening 20141 in communication with the containing cavity, the stone discharging opening 20141 is designed to have a certain slope to buffer the impact force of the falling stone and reduce the impact on the film. The stone loading cylinder 2012 and the stone discharging frame 2013 are both arranged in the containing cavity of the shell 2014, and the stone loading cylinder 2012 and the stone discharging frame 2013 are coaxially arranged, the stone discharging frame 2013 is located on the side of the stone loading cylinder 2012 close to the stone discharging opening 20141, one end of the stone discharging frame 2013 abuts against the bottom of the stone loading cylinder 2012, and the other end of the stone discharging frame 2013 extends out of the bottom of the shell 2014 and is fixedly connected with the second gear 203. The stone loading cylinder 2012 is used for containing the stones, and the bottom of the stone loading cylinder 2012 is provided with a slanting stone discharging pipe extending to the side of the stone discharging frame 2013, and the stones in the stone loading cylinder 2012 fall onto the stone discharging frame 2013 through the slanting stone discharging pipe.

[0046] The stone discharging frame 2013 comprises a stone discharging frame body, connecting columns 20131 and supporting columns 20132 located at opposite sides of the stone discharging frame body. The shape of the stone discharging frame body matches the shape of the accommodating cavity of the shell 2014, so as to avoid the stone falling from the gap between the stone discharging frame body and the inner wall of the shell 2014. The supporting columns 20132 are located at the side of the bevelled stone discharging pipe and abut against the bottom of the stone loading cylinder 2012, so as to make the stone discharging frame body and the bottom of the stone loading cylinder 2012 have a certain gap, reserve a certain activity space for the stone falling on the stone discharging frame body, and make the stones in the stone loading cylinder 2012 orderly discharged to the stone discharging frame body. The connecting columns 20131 extend from the bottom of the shell 2014 and are fixedly connected with the second gear 203. The stone discharging frame 2013 can rotate along the axial direction under the driving of the second gear 203, so that the stones falling on 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.

[0047] Further, in order to ensure the stability between the stone discharging frame 2013 and the stone loading cylinder 2012, a limiting groove can be arranged at the bottom of the stone loading cylinder 2012, and the end of the supporting column 20132 is embedded in the limiting groove.

[0048] The support 2011 comprises a fixed ring 20111 and a support rod 20112. The fixed ring 20111 and the support rod 20112 are fixedly connected, the fixed ring 20111 is sleeved on the outer wall of the top of the shell 2014, and the support rod 20112 is rotationally connected with the rack 101 through the support shaft 2015. The fixed ring 20111, the shell 2014 and the stone loading cylinder 2012 are assembled together by bolts and can be freely disassembled.

[0049] It should be noted that the axes of the shell 2014, the stone loading cylinder 2012 and the stone discharging frame 2013 are perpendicular to the plane where the rack assembly 1 is located, so as to ensure that the stones are smoothly discharged under the action of the centrifugal force and gravity. In addition, the first gear 106 and the second gear 203 are helical gears, the first gear 106 is coaxially arranged with the rear end rotating 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 rotating shaft 103 to the stone discharging frame 2013.

[0050] The displacement driver 202 can be a hydraulic lifting cylinder fixed on the frame 101, and the moving end of the hydraulic lifting cylinder is connected with the support 2011. The hydraulic lifting cylinder drives the support 2011 to rotate around the support shaft 2015 through lifting movement, so as to move the stone expelling device 201 around the support shaft 2015. The lifting hydraulic cylinder is used to lower the stone expelling device 201 to realize the meshing of the second gear 203 and the first gear 106 when the stone expelling is needed; and the lifting hydraulic cylinder is also used to lift up the stone expelling device 201 to realize the disengagement of the second gear 203 and the first gear 106 when the stone expelling is not needed.

[0051] Of course, in other embodiments, the displacement driver 202 can also be other types of structures capable of driving the stone expelling device 201 to displace, such as a linear stepping motor, a servo motor or a pneumatic driver, etc., as long as it can drive the stone expelling device 201 to displace in the horizontal direction or the vertical direction, so as to realize the meshing or disengagement of the second gear 203 and the first gear 106.

[0052] In an embodiment, the front end rotating shaft 102 and the rear end rotating shaft 103 are both telescopic rotating shafts, i.e. rotating shafts capable of adjusting the length by telescoping along the axial direction. For example, the telescopic rotating shaft is connected by two or more than two shaft rods, and the adjacent two shaft rods can slide towards or away from each other, so as to adjust the length of the rotating shaft. By adjusting the telescopic length of the front end rotating shaft 102 and the rear end rotating shaft 103, the width of the frame assembly 1 can be adjusted. In this way, the frame assembly 1 can be adapted to different widths of the reflective film according to the needs of different film coating widths.

[0053] Referring to Figure 1 and Figure 4 , the film coating mechanism 3 comprises 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 running direction of the frame assembly 1, and both ends of the film guide cylinder 301 are fixed on the frame 101 for guiding the reflective film.

[0070] Step 2, when the traction device 100 reaches the starting coordinate, the control system 8 sends the mulching information to the mulching mechanism 3 based on the starting coordinate information, and the mulching mechanism 3 starts the mulching operation; at the same time, the control system 8 sends the stone removing signal to the stone removing mechanism 2, and the displacement driver 202 drives the stone remover 201 to move to make the second gear 203 engage with the first gear 106, and the stone remover 201 covers the stone on the reflective film.

[0071] Wherein, O0(X0, Y0, Z0) is set as the starting coordinate of the mulching operation of a row of fruit trees, and O d (X d , Y d , Z d ) is set as the end coordinate of the mulching operation of a row of fruit trees.

[0072] When the traction device 100 reaches the starting coordinate O0(X0, Y0, Z0), the control system 8 transmits the mulching 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 guided out along the film guide port of the film guide cylinder 301. At the same time, the control system 8 transmits the stone removing signal to the displacement driver 202, and the displacement driver 202 drives the stone remover 201 to move to make the second gear 203 engage with the first gear 106, so that the stone remover 201 covers the stone on the reflective film.

[0074] Step 3, when the traction device 100 reaches the end coordinate, the control system 8 sends the stop mulching information to the mulching mechanism 3 based on the end coordinate information, and the mulching mechanism 3 stops the mulching operation; at the same time, the control system 8 sends the stop stone removing signal to the stone removing mechanism 2, and the displacement driver 202 drives the stone remover 201 to move to make the second gear 203 disengage with the first gear 106, and the stone remover 201 stops covering the stone.

[0075] When the traction device 100 completes the covering of a row of reflective film and reaches the end coordinate O d (X d , Y d , Zd When the control system 8 receives the signal from the detection device 7, the control system 8 will send a stop film signal to the displacement driver 202, the displacement driver 202 drives the stone remover 201 to move, the second gear 203 separates from the first gear 106, and the stone remover 201 stops covering the stone.

[0076] In an embodiment, the control system 8 can send a stone removal signal to the hydraulic pump 9, the hydraulic pump 9 increases the delivery of hydraulic oil to the lifting hydraulic cylinder, the lifting hydraulic cylinder rises so that the stone remover 201 is lifted, thereby separating the second gear 203 from the first gear 106.

[0077] In an embodiment, the reflective film covering machine further comprises a film cutting mechanism 4 connected with the control system 8, the film cutting mechanism 4 comprises a film cutting knife 401, a film cutting bracket 402 and a film cutting driver, please refer to the description above, which will not be repeated here. Therefore, after stopping the film covering operation and the stone covering operation in the above step 3, the following steps are included:

[0078] The control system 8 sends a film cutting signal to the film cutting driver, the film cutting driver drives the film cutting knife 401 to reciprocate to complete a film cutting.

[0079] After completing the reflective film covering operation of one row of fruit trees, the traction device 100 pulls 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 of the next row of fruit trees.

[0080] During the whole working process, the fruit trees are detected by the detection device 7, and after the fruit trees are detected, the film covering and film cutting are performed, which can reduce unnecessary reflective film covering and avoid waste of reflective film.

[0081] The bias adjustable orchard reflective film covering machine and the film covering method of the present application, when the traction device 100 drives the reflective film covering machine to advance, when reaching the starting coordinate, under the driving of the rotary driver 302, the film hanging shaft rotates to make the reflective film be guided out of the film guiding cylinder 301 and then be laid on the ground, with the traction device 100 advancing, the rear end rotating shaft 103 rotates to drive the first gear 106 to rotate, the second gear 203 engaged with the first gear 106 rotates to drive the stone arranging frame 2013 to rotate, the stone in the stone loading cylinder 2012 enters the stone arranging frame 2013, and under the action of the centrifugal force and the gravity, the stone rolls to the edge of the stone arranging frame 2013, and then falls to the reflective film through the stone arranging opening 20141 on the outer shell 2014, to achieve the film pressing effect. When the reflective film covering work of one row of fruit trees is completed, the stone arranging device 201 is lifted by the control hydraulic lifting cylinder, and the stone stops rolling. The whole process is automatically completed with the operation of the traction device and the reflective film covering machine, and the artificial stone covering and film cutting are not needed, the labor intensity of the workers is low, the work efficiency is high, the workers can complete the film covering work by assisting beside the film covering machine, and the present application is very suitable for the work in the orchard environment. Moreover, the laid reflective film is flat and straight, is not easy to be blown away after the film covering is completed, and the reflective effect is better.
