Description

Technical Field

[0001] This invention relates to a fully automatic waste coconut coir strip recycling and processing device, specifically an integrated device capable of automatically breaking down plastic packaging bags of waste coconut coir strips, crushing coconut coir substrate blocks, and separating coconut coir substrate from crop roots and stems. Background Technology

[0002] Planting substrates are production materials used in large quantities and with relatively high unit prices during the long-season cultivation of vegetables in large-scale multi-span greenhouses. Coconut coir strips, due to their good water retention, fertilizer retention, and air permeability, are one of the commonly used soilless cultivation substrates for facility vegetable cultivation in my country. They are usually returned to the field or sold at a low price after one year of use.

[0003] However, the traditional recycling process of waste coconut coir strips suffers from problems such as high labor intensity, high recycling costs, and low reuse efficiency. The main reasons are as follows: (1) Before returning coconut coir substrate to the field, the plastic packaging bags need to be removed and the coconut coir substrate needs to be crushed. This is mainly done manually, which is labor-intensive and inefficient; (2) Before returning or reusing coconut coir substrate to the field, the coconut coir substrate needs to be separated from the crop roots. This process is complicated, resulting in high recycling costs, low processing and reuse efficiency, and failure to fully realize its potential resource value. With the rapid development of facility agriculture, the demand for efficient recycling technology of waste coconut coir strips is increasing. However, at present, my country still does not have automatic bag breaking, crushing, root separation and coconut coir recycling equipment or devices for waste coconut coir strips.

[0004] Therefore, developing a highly automated, easy-to-operate, and efficient coconut coir strip recycling and processing equipment is of great practical significance. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic waste coconut coir strip recycling and processing device, which can automatically complete the following tasks: (1) automatically breaking open the outer packaging bag of waste coconut coir strips; (2) efficiently crushing coconut coir blocks mechanically for easy subsequent processing; and (3) automatically separating coconut coir substrate from crop roots. The invention and application of this device can reduce the manpower input in the recycling process of waste coconut coir strips, reduce recycling costs, and improve the resource reuse rate of waste coconut coir strips.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figures 1 to 8 As shown, the present invention provides a fully automatic waste coconut coir strip recycling and processing device, including a bag breaking device, a packaging bag and coconut coir substrate separation device, a coconut coir substrate conveying device, a coconut coir substrate and crop root separation device connected in sequence, and a control system 17. The control system 17 is electrically connected to the bag breaking device, the packaging bag and coconut coir substrate separation device, the coconut coir substrate conveying device, and the coconut coir substrate and crop root separation device, respectively.

[0041] In some preferred embodiments, the bag-breaking device includes a feeding assembly 1, a fixing clamp 2, a bag-breaking knife 3, and a support leg 4.

[0042] The feeding assembly 1 includes a feeding inlet and two parallel conveyor belts. The feeding inlet is used to manually feed coconut coir strips, and the conveyor belts are used to transport the coconut coir strips to the fixing clamp 2. The fixing clamp 2 includes two steel plates located above the conveyor belts. The bag-breaking knife 3 is located in the middle of the conveyor belt, below the coconut coir strips. The support legs 4 are located below the feeding assembly 1 and are used to support and fix the conveyor belts.

[0043] The fixing clamp 2 is composed of two stainless steel plates located above the conveyor belt. The edge of the steel plate near the feed inlet is slightly curved to facilitate the smooth feeding of the coconut coir bag into the feed inlet, and to facilitate the feeding and fixing of the coconut coir strip from one end of the feed inlet to the rear. When the bag-breaking knife 3 performs the bag-breaking operation, it fixes the coconut coir strip so that it does not move.

[0044] The bag-breaking knife 3 is located in the middle of the conveyor belt, below the coconut coir strips, and cuts the packaging bag of the coconut coir strips from the middle of the bottom of the coconut coir strips during the conveying process.

[0045] The support feet 4 are used to support and fix the conveyor belt and other devices, so that the height of the device is easy for workers to manually put the coconut coir bags into the feed inlet.

[0046] In some preferred embodiments, the width between the two parallel conveyor belts (including the conveyor belts) is slightly greater than the width of the coconut coir strip (150 mm), and the distance from the feed inlet to the fixed clamp 2 is slightly greater than the length of the coconut coir strip (1000 mm).

[0047] In some preferred embodiments, the packaging bag and coconut coir substrate separation device includes a roller conveyor 5, a baffle 6, a robotic arm 7, and a sliding track 8.

[0048] The roller conveyor 5 is used to transport the broken coconut coir strips from the bag-breaking device to the operating position of the robotic arm 7. The baffle 6 is located at the end of the roller conveyor 5 to block the coconut coir strips and prevent them from falling. The robotic arm 7 is extendable and used to grab the coconut coir strips and lift them from the roller conveyor 5 to a certain height. After reaching a certain height, the robotic arm 7, holding the coconut coir strips, moves them along the sliding rail 8 to above the coconut coir substrate conveying device, and then opens to release the coconut coir blocks through the broken bottom of the packaging bag into the coconut coir substrate conveying device. The sliding rail 8 allows the robotic arm 7 to slide from the roller conveyor 5 to the coconut coir block crusher and the waste packaging bag collection device.

[0049] Because the gripping position of the robotic arm 7 has fine short needles, it can simultaneously release the coconut coir block and cause the coconut coir strip packaging bag to adhere to the robotic arm 7. After releasing the coconut coir block, the robotic arm 7 and the adhered packaging bag continue to move outward along the sliding track and stop above the waste packaging bag collection device. The robotic arm 7 then opens to release the packaging bag to the collection device and returns to the roller conveyor 5 to prepare to grab the next coconut coir strip.

[0050] In some preferred embodiments, the coconut coir substrate conveying device includes a coconut coir block crusher 9, a bucket elevator 10, a hopper 11, and a first screw conveyor 12.

[0051] The bucket elevator 10 is located directly below the coconut coir block crusher 9 and is used to lift the falling coconut coir substrate to a certain height and transport it to the funnel 11. The funnel 11 is used to receive the crushed coconut coir substrate and release it to the first screw conveyor 12. The first screw conveyor 12 is located directly below the funnel 11 and is used to rotate and transport the coconut coir substrate forward to the coconut coir substrate and crop root separation device.

[0052] In some preferred embodiments, the coconut coir block crusher 9 includes a rotating shaft, needle-type stirring blades, and a funnel-type container. When the rotating shaft rotates, it drives the needle-type stirring blades to rotate, breaking up the lumps of coconut coir matrix. The broken coconut coir matrix falls into the bucket elevator 10 through the funnel-type container.

[0053] In some preferred embodiments, baffles 6 are provided at regular intervals on the conveyor belt of the bucket elevator 10 to prevent the conveyed coconut coir substrate from overflowing.

[0054] In some preferred embodiments, the coconut coir substrate and crop root separation device includes a separation roller 13, a funnel device 14, a root collection device 15, and a second screw conveyor 16.

[0055] The separating roller 13 includes a rotating shaft and a perforated outer casing. When the rotating shaft rotates, it drives the separating roller 13 to rotate, and the roots move to the root collection device 15 under the continuous rotation of the roller. The small perforations of the separating roller 13 allow finely broken coconut coir substrate to fall through the holes into a funnel device 14 below the roller, while the roots remain in the separating roller 13. The roots move to the root collection device 15 under the continuous rotation of the separating roller 13. The funnel device 14 is located directly below the separating roller 13 and receives the coconut coir substrate separated from the roots; the root collection device 15 is located on the other side of the separating roller 13 and is used to collect the crop roots separated from the coconut coir substrate. The second screw conveyor 16 is located below the funnel device 14 and is used to spirally transport the coconut coir substrate forward to the discharge port.

[0056] In some preferred embodiments, the bag-breaking device, the packaging bag and coconut coir substrate separation device, the coconut coir substrate conveying device, and the coconut coir substrate and crop root separation device are all equipped with protective devices to prevent accidental damage.

[0057] The working principle of this invention is as follows:

[0058] 1. Feeding: The operator manually places the coconut coir strips into the feed inlet. The feed inlet is designed to be spacious, with the width between the two parallel conveyor belts (including the conveyor belts) slightly greater than the width of the coconut coir strip (150mm), and the distance from the feed inlet to the fixed clamp slightly greater than the length of the coconut coir strip (1000mm), making it convenient for the operator to place the coconut coir strips.

[0059] 2. Bag Breaking: The coconut coir strips enter the equipment through the feed inlet and first reach the area of ​​the bag breaking knife 3. The fixing clamp 2 of the bag breaking knife 3 fixes the position of the coconut coir strips to prevent them from moving during the cutting process. The movable blade rotates one revolution, cutting the packaging bag of the coconut coir strips from the bottom middle position, thus breaking the bag.

[0060] 3. Separation of coconut coir strips from packaging bags: After the packaging bags are broken, the coconut coir strips are transported to the area below the robotic arm 7 via the roller conveyor 5. Guided by the control system 17, the robotic arm 7 precisely grasps the coconut coir strips and moves them above the coconut coir block crusher 9. The robotic arm 7 then releases the coconut coir blocks through the broken bottom of the packaging bag into the crusher 9. Because the gripping position of the robotic arm 7 has fine, short needles, the packaging bag is attracted to the robotic arm 7 while the coconut coir blocks are being released. After releasing the coconut coir blocks, the robotic arm 7 and the attracted packaging bag continue to move outward along the sliding track and stop above the waste packaging bag collection device. The robotic arm 7 then releases the packaging bag into the collection device and returns to the roller conveyor 5 to prepare to grasp the next coconut coir strip.

[0061] 4. Separation of coconut coir substrate from crop roots: The crushed coconut coir substrate is transported by bucket elevator 10 to funnel 11, and then falls into first screw conveyor 12. First screw conveyor 12 transports coconut coir substrate to separation drum 13. The small hole design of separation drum 13 allows the finely crushed coconut coir substrate to fall through the holes into funnel device 14 below the drum, while the roots move to root collection device 15 under the continuous rotation of separation drum 13.

[0062] 5. Discharge: The separated coconut coir substrate and crop roots are discharged from their respective outlets, completing the entire recycling process. The coconut coir pores and crop roots can be collected and used for further processing or recycling.

[0063] The entire equipment is operated automatically by the control system 17, which includes the speed and movement of the conveyor belt, bag-breaking knife 3, roller conveyor 5, robotic arm 7, coconut coir block crusher 9, bucket elevator 10, first screw conveyor 12, and separating roller 13. The control system 17 also monitors the equipment's operating status, such as feed rate, separation efficiency, and equipment operating condition, and automatically adjusts the operating parameters of each device based on the monitoring results to optimize the separation effect.

[0064] Through the above implementation examples, the fully automatic waste coconut coir strip recycling and processing device of the present invention can efficiently and automatically complete the recycling and processing of coconut coir strips, greatly reducing manpower input and improving the efficiency and quality of coconut coir strip recycling.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
