Description

Technical Field

[0001] This invention belongs to the field of facility agriculture engineering technology, and in particular relates to a greenhouse cultivation trough film recycling machine, recycling system and recycling method. Background Technology

[0002] In intelligent multi-span greenhouses, hydroponics typically uses suspended cultivation troughs for placing coconut coir strips and other materials. During cultivation, sap can accumulate on the surface of these troughs, calcifying and forming crystals. This requires significant manual labor for greenhouse cleaning. Currently, covering the cultivation troughs with a film reduces corrosion from the accumulated material and simplifies cleaning. However, this leads to a high labor demand for manually collecting used film within the greenhouse. Therefore, there is an urgent need for a rapid film removal system to reduce labor intensity, improve efficiency, minimize greenhouse downtime, and ultimately increase greenhouse productivity. Summary of the Invention

[0003] The purpose of this invention is to provide a greenhouse cultivation trough film recycling machine that can automatically recycle the cultivation trough film.

[0005] Preferably, the greenhouse cultivation trough film recycling machine further includes: a film guide that is cantilevered on the frame in a manner that is spaced apart from or opposite to belt roller III or belt roller I, wherein the inlet width of the film guide is smaller than the width of the belt.

[0006] Preferably, the frame is a ladder-shaped frame structure, which is divided into two sections, namely section A and section B, and is hinged together by a belt roller shaft at the middle part where sections A and B are adjacent.

[0007] Preferably, a belt roller II is provided at the belt roller shaft to provide intermediate support for the belt.

[0008] Preferably, a positioning pin and an arc-shaped locking block with a positioning hole are respectively provided at the middle adjacent part of the two frame sections. When the recycling machine is in the unfolded state, the positioning pin can be inserted into the positioning hole.

[0010] Preferably, the roller portion of belt roller I is integrally formed as a wheel, or the wheel and roller portion are separately mounted on the frame.

[0011] Preferably, the two frame sections achieve a shrinking state with a smaller distance between their relatively free ends by folding or retracting and fixing them relative to each other. Corresponding to the folding method, locking blocks and positioning pins are formed on the two frame sections respectively; corresponding to the retraction method, elongated slots and positioning posts that are movably positioned in the elongated slots are formed on the two frame sections respectively.

[0012] According to another aspect of the present invention, a recycling system is provided, characterized in that it includes a greenhouse cultivation trough film recycling machine, a cultivation trough, and a cultivation trough hook for suspending the cultivation trough as described in any one of claims 1 to 2.

[0014] Film end winding steps: Wrap the free end of the film around the belt;

[0015] Mounting steps: Place the recycling machine on the upper surface of the cultivation trough, so that the guide wheels straddle both sides of the cultivation trough and contact the side surface;

[0016] Film winding steps: Turn on the motor, and the motor drives the belt roller I to rotate through the drive belt, which in turn drives the belt to rotate continuously, so that the film on the cultivation trough is continuously wound onto the belt.

[0017] The advantages of this invention are: it enables rapid cleaning of the film covering, thereby reducing labor intensity, improving work efficiency, reducing greenhouse downtime, and thus increasing greenhouse output.

[0026] <Overall Composition>

[0027] like Figures 1-5 As shown, an exemplary embodiment of the present invention provides a greenhouse cultivation trough film recycling system, including as follows: Figure 1The recycling machine 31 shown is as follows: Figure 3 The cultivation trough 17 shown is, for example, in the form of a Z-shaped cross section. Figure 5 The cultivation trough hook 19 shown is suitable for retrieving the surface coating while moving along the upper surface of a long, narrow cultivation trough.

[0028] The recycling machine 31 includes: frame 1, belt roller I 2, belt roller II 3, belt roller III 4, belt roller shaft 5, belt 6, drive belt (e.g., triangular type) 7, motor (e.g., geared motor type) 8, drive pulley (e.g., triangular type) 9, motor driver 10, battery 11, wheel 12, guide wheel 13, positioning pin 14, compression spring 15, film guide 16, etc.

[0029] The frame 1 is a ladder-shaped frame structure with two parallel longitudinal beams 20 and multiple transverse beams 21 spaced between the two longitudinal beams 20. It is generally divided into front and rear sections, as shown below. Figure 1 The sections A and B shown (or the first and second ladder sections) are hinged together by the belt roller shaft 5 at the midpoint between adjacent sections A and B (position C at belt roller II 3). With this structure, the frame 1 can be folded up. Figure 2 As shown, belt 6 is in a slack, detachable state. At both ends of the frame 1, i.e., the free ends of the longitudinal beams 20 on opposite sides of sections A and B, belt rollers I2 and III4 are rotatably fixedly mounted using belt roller shafts 5. Belt 6 wraps around belt rollers I2, II3, and III4 (collectively referred to as belt rollers). Figure 1 The A and B segments shown are in their deployed working state, and Figure 2 In the folded state shown (hereinafter referred to as the retracted state), belt roller II3 can serve as a relay support for belt 6.

[0030] In one embodiment, the frame 1 is made of aluminum alloy, and the belt rollers (belt roller I2, belt roller II3, and belt roller III4) are made of nylon to ensure a lightweight vehicle body and reduce the manual labor intensity when disassembling the film and transporting it to other cultivation tanks. The belt 6 is made of silicone, and its circumference is slightly smaller than the belt length that belt rollers I2 and III4 can support in the unfolded working state to ensure belt tension.

[0031] The motor 8 is fixed to the rear side frame of the frame 1, for example, on the crossbeam and / or longitudinal beam of section A. A drive pulley 9 is mounted on the motor output shaft. The drive pulley 9 is connected to the belt roller I2 via the drive belt 7, thereby driving the belt roller I2. Therefore, as follows... Figure 6As shown, the belt roller I2 includes a roller section 27 and a roller section 29. A V-shaped groove 28 is provided on the roller section 27, and the V-shaped drive belt 7 is embedded inside the groove 28, saving space and preventing interference between the drive belt 7 and the belt 6. The roller section 29 has a larger diameter than the roller section 27, forming a guiding space for accommodating the recycled film.

[0032] A motor driver 10 is also fixed on the rear side frame of the frame 1 to drive and control the motor 8. A battery 11 is installed on the second crossbeam at the rear end of the frame 1 to power the entire recycling machine.

[0033] Three pairs of wheels 12 are installed at the front, middle and rear of the bottom of the frame 1 so that the recycling machine 31 can move on the cultivation trough 17. Guide wheels 13 are installed at the bottom of the recycling machine 31, such as at the front and rear ends of the longitudinal beam 20. The guide wheels 13, which are arranged laterally opposite to each other, abut against the sides of the cultivation trough 17 to prevent the recycling machine 31 from falling off when it moves.

[0034] A locking block 24 is provided at the folding part adjacent to the middle of the frame 1 to ensure that when the recycling machine 31 is unfolded, the A section and B section of the frame 1 are flattened at a 180-degree angle and folded into a 90-degree right angle. It is also equipped with a positioning pin 14. When the recycling machine 31 is in the unfolded state, the positioning pin 14 is inserted into the positioning hole 25 of the frame 1 to prevent the frame 1 from bulging under the tension of the belt 6.

[0035] In one embodiment, a positioning pin 14 is fixedly installed on section A of the frame 1, and a corresponding arc-shaped locking block 24 is fixedly installed on section B. The locking block 24 has a positioning hole 25. Of course, a second positioning hole can also be provided on the frame 1 or the locking block 24 to maintain the retracted state.

[0036] like Figure 4 As shown, one end of the compression spring 15 abuts against the boss 22 of the frame 1, and the other end abuts against the belt roller shaft 5 of the belt roller III 4, forming a tensioning mechanism that tensions the belt 6. Four compression springs 15 are installed on both sides of the front of the recycling machine 31. An adjusting nut 23 is installed at one end of the belt roller III 4 of the compression spring 15; adjusting the position of the adjusting nut 23 adjusts the tension on the belt 6. This tensioning mechanism can also be installed on the belt roller I 2.

[0037] The foremost part of the recycling machine 31 is a film guide 16, formed as, for example, a ring with a rectangular hole, which can be mounted on the B-section side frame of the frame 1 via a support arm 20 in a manner that is spaced apart from and opposite to the belt roller Ⅲ4. For example, it can be cantilevered to the side frame of the frame 1, which facilitates... Figure 2 The belt 6 is to be replaced as shown.

[0038] like Figure 3 , 5As shown, the recycling machine 31 configured in this way can be placed on the upper surface of the cultivation trough 17 and performs film recycling while traveling along the upper surface. The two side surfaces 27 of the cultivation trough 17 interact with the guide wheels 13 to perform guiding and correction functions. The bottom surface of the cultivation trough 17 can be supported on the cultivation rack or suspended by the cultivation trough hook 19. In this case, the cultivation trough hook 19 is configured to leave a gap between the cantilever 26 and the side surface 27 for the guide wheels 13 to pass through. In one embodiment, the two lower legs 30 of the Z-shaped cross section of the cultivation trough 17 are respectively hooked and supported by the two hook portions 31 of the cultivation trough hook 19, and the guide wheels 13 pass through the gap between the side surface 27 above the legs 30 and the cantilever 26 above the hook portions.

[0039] <Roll film recycling method>

[0040] Film end winding step: During recycling, the free end of the film 18 is passed through the film guide 16 and then wound onto the belt 6. Here, the inlet width of the film guide 16 is smaller than the width of the belt, which ensures that even if the width of the film 18 is greater than the inlet width of the film guide 16, it will be correspondingly tightened during the recycling process and will not wrap around to the outside of the belt roller rim, thus avoiding film tangling. At this time, the film 18 can be manually wound full once, and the film 18 itself can press down the film end. Then, the motor 8 can be started to continue film winding and recycling.

[0041] Mounting steps: Place the recycling machine 31 on the flat upper surface of the cultivation trough 17. When placing it, ensure that the guide wheels 13 straddle both sides of the cultivation trough 17 and contact the side surface 27 to prevent the recycling machine 31 from falling off.

[0042] The order of the above-mentioned film end winding step and the mounting step is not limited. For example, after the mounting step, the film end can be attached to the upper surface of the belt 6. By using the adsorption force and surface tension between the two, the motor 8 can be turned on briefly to make the belt 6 rotate more than one revolution. This can also ensure that the film 18 on the cultivation tank 17 is wound onto the recycling machine belt 6, which is suitable for starting the subsequent film winding step.

[0043] Film winding process: The motor 8 is turned on, and the motor 8 drives the belt roller I2 to rotate via the drive belt 7, which in turn drives the belt 6 to rotate continuously on each belt roller. This causes the film 18 on the cultivation trough 17 to be continuously wound onto the belt 6. Since the film 18 is adhered to the cultivation trough 17 and the recycling machine has wheels 12, the recycling machine 31 is pulled forward by the reaction force transmitted by the film 18 while it is winding up the film 18, until it reaches the end of the cultivation trough 17.

[0044] More specifically, the film 18 is normally attached to the cultivation trough 17 and can be easily torn off with a little force. The recycling machine 31 winds the film 18 onto the belt 6, and the motor 8 drives the belt 6 to rotate. At the same time, while the film 18 is being wound onto the belt 6, the recycling machine 31 is also passively dragged forward by the film 18 until it reaches the end of the cultivation trough 17. Then, the recycling machine 31 is manually folded at a right angle and the film 18 is removed. No power needs to be applied to the wheels 12 of the recycling machine 31; the recycling machine is simply dragged forward by the film 18.

[0045] After reaching the end of the cultivation trough 17, the recycling machine is manually moved to the ground. After pulling open the positioning pins 14 on both sides of the middle, the recycling machine can be folded in half. After folding, the film 18 wrapped around the recycling machine can be removed. After the film 18 is removed, the recycling machine is unfolded again, and the positioning pins 14 are put back in place to ensure that the middle of the recycling machine will not bulge under the tension of the belt 6.

[0046] The recycling machine 31 is placed on the remaining cultivation troughs 17 in sequence to complete the recycling of the film 18 on the remaining cultivation troughs 17. The film recycling work on the entire greenhouse cultivation troughs 17 is completed in this way.

[0047] The above example illustrates the connection mechanism between the positioning pin 14 and the arc-shaped locking block 24. However, it is not limited to this. A bias spring or a geared motor can also be used to adjust the relative position of section A and section B. Alternatively, a guide rail connection mechanism can be used instead of a rotary bending mechanism. As long as the two sections of the frame 1 can be adjusted between the unfolded state and the retracted state (including the retracted state, such as folding or retraction, which reduces the distance between the relative free ends of sections A and B), the relative positions of the two sections can be adjusted. For example, a long slot can be opened on section A, and a positioning post can be set on section B. By using the different positions of the positioning post in the long slot, the longitudinal extension and retraction of the recycling machine 31 can be achieved, and the replacement of the belt 6 or the removal of the wound film 18 can be completed.

[0048] The above example illustrates a belt roller I1 for driving the recycled film and a separately provided wheel 12. However, it is not limited to this; the wheel 12 can also be integrally formed as the roller portion 29 of the belt roller I1. In this case, the roller portions of the belt rollers II3 and III4 can also be correspondingly formed as wheels. In addition to the roller portion with the wheel integrally formed, a wheel in the form of a rubber ring can also be interference-fitted onto the outer peripheral wall of the roller portion. This further simplifies the structure.

[0049] The above example illustrates a wheel 12 that travels along the upper surface (first surface) of the cultivation trough, and a guide wheel 13 that guides along the side surface 27 (another surface) of the cultivation trough. However, it is not limited to this. In the case where the cultivation trough is formed in other forms such as a long flat plate, the other surface can also be guided by a groove or back formed in the longitudinal direction.

[0050] The above example illustrates the film guide 16 arranged opposite to belt roller III4, but it is not limited to this; it can also be arranged opposite to belt roller I2 when the counterweight is balanced.
