Description

Technical Field

[0002] In the pineapple farming industry, the disposal of post-harvest waste plants has always been a thorny issue. Traditional disposal methods include manual removal, incineration, or composting, but these methods are generally inefficient, labor-intensive, and potentially polluting. Manual removal is not only time-consuming and labor-intensive, but also difficult to meet the needs of large-scale agricultural production. Incineration, while quick, causes air pollution and wastes recyclable resources. Natural composting, while environmentally friendly, requires a long time and space, limiting its scope of application.

[0003] While there are numerous mechanical devices on the market specifically designed for the treatment of crop waste, existing general-purpose equipment often struggles to achieve optimal treatment results for pineapples due to their unique growth patterns and the characteristics of waste plants (such as hard, thorny leaves). These devices often suffer from poor adaptability and incomplete treatment, resulting in low resource recovery rates and ineffective reduction of environmental impacts.

In addition, in this specific embodiment, if the connection or fixing method between the components is not particularly specified, the connection or fixing method can be fixed by bolts or pins commonly used in the prior art, or by pin connections, etc. Therefore, it will not be described in detail in this embodiment.

[0032] Example 1

[0033] This embodiment discloses a self-propelled pineapple waste plant stem and leaf separation processing device, which is mainly used to separate the waste pineapple plants into leaves, stems and roots during recycling, and the leaves and stems are recycled. The details are as follows:

[0034] See also Figure 1The stem and leaf processing equipment includes a plant recovery module 1, which is composed of two conveyor belts 11 with opposite conveying surfaces. The conveyor belts 11 act on the stem and leaf parts of the plant, clamp the plant and pull the plant out of the soil with the help of the conveyor belts 11; the plant recovery module 1 adopts a double conveyor belt 11 design, and the surfaces of the two conveyor belts 11 are opposite to each other to form a clamping space; when the discarded pineapple plant enters this space, the friction and clamping force between the conveyor belts 11 pull the plant out of the soil, which significantly improves the processing efficiency, reduces manual intervention, and solves the problem of time-consuming and labor-intensive manual removal. A stem-and-leaf separation module 2, which is arranged on the plant recovery module 1, and is used to separate the stems and leaves of the plants on the conveyor belt 11, and divide the plants into leaves and stems; a leaf recovery module 3, which is arranged behind the stem-and-leaf separation module 2 along the conveying direction of the conveyor belt 11, and is used to load the leaves of the plants after the stems and leaves are separated; a stem recovery module 4, which is arranged at the end of the plant recovery module 1, and is used to load the stems of the plants after the stems and leaves are separated.

[0035] See also Figure 2 , the conveyor belt 11 is a chain transmission component, and the conveyor belt 11 includes a conveyor chain 12. The use of a chain as a transmission component not only increases the strength and durability of the transmission system, but also can provide sufficient friction to effectively clamp and transmit discarded pineapple plants. The conveyor chain 12 is provided with a first transmission gear 13 and a second transmission gear 14 at the feed end and the discharge end of the plant recovery module 1 for transmission, ensuring that the conveyor chain 12 can run smoothly during the entire operation. The setting of the first transmission gear 13 and the second transmission gear 14 allows the feed end and the discharge end of the plant recovery module 1 to be open, so that the plant recovery module 1 can fix and remove the plant; it simplifies the process of fixing and removing the plant, makes the entire operation process smoother, and improves work efficiency.

[0036] See also Figure 2, the stem and leaf processing equipment also includes a carrier 6, and the carrier 6 is used to assemble the plant recovery module 1, the stem and leaf separation module 2, the leaf recovery module 3 and the stem recovery module 4; the integrated design not only facilitates the overall movement and operation of the equipment, but also improves the coordination and work efficiency between the various modules. The frame 15 of the conveyor belt 11 is mounted on the carrier 6 in a swinging manner, allowing the conveyor belt 11 frame 15 to adjust the angle according to changes in the terrain, ensuring that the equipment can operate stably in different working environments. The frame 15 of the conveyor belt 11 is provided with a roller 16 at the feed end of the plant recovery module 1, and the plant recovery module 1 is supported by the contact between the roller 16 and the ground; it not only increases the stability of the equipment, but also helps to reduce soil compaction and protect the farmland environment. The frame 15 of the conveyor belt 11 is provided with a threaded cone at the feed end of the plant recovery module 1, and the threaded cones are respectively provided on both sides of the feed end of the plant recovery module 1. The rotation direction of the threaded cones on both sides is upward along the feed end of the plant recovery module 1. The upward rotation of the threaded cone lifts up the drooping leaves of the plant, allowing the plant recovery module 1 to better clamp the plant.

[0037] See also Figure 2 The stem-and-leaf separation module 2 includes a stem-and-leaf separation knife 21, which is arranged perpendicular to the conveying surface of the conveyor belt 11. This ensures that when the pineapple plant is transported to the stem-and-leaf separation knife 21, the connection between the leaves and the stem can be effectively cut, so that the leaves can be smoothly separated from the stem. The stem-and-leaf separation knife 21 is arranged close to the leaf recovery module 3, which is arranged in the conveying direction of the conveyor belt 11. The rotation direction of the stem-and-leaf separation knife 21 along the conveying direction of the conveyor belt 11 points to the leaf recovery module 3; in this way, after cutting, the leaves can fall directly into the leaf recovery module 3, reducing the possibility of leaf scattering and improving collection efficiency. The stem-and-leaf separation module 2 also includes a root-and-stem separation knife 22, which is arranged parallel to the root-and-stem separation knife 22; the main function of the root-and-stem separation knife 22 is to cut the connection between the root and the stem of the plant, so that the stem can be processed separately. This double-cutter 5122 design ensures the efficient completion of both the stem-and-leaf separation and the root-and-stem separation processes.

[0038] See also Figure 2The leaf recovery module 3 includes a leaf conveyor belt 31 and a leaf container. The feed end of the leaf conveyor belt 31 is located in the conveying direction of the plant recovery module 1, and the feed end of the leaf conveyor belt 31 is close to the stem-leaf separation knife 21; the leaf container is located at the discharge end of the leaf conveyor belt 31; when the stem-leaf separation module 2 separates the stems and leaves of the plant, the plant leaves rely on the inertia brought by the plant recovery module 1 and the stem-leaf separation knife 21 to move to the feed end of the leaf conveyor belt 31. By rationally arranging the feed end position of the leaf conveyor belt 31, the process from stem-leaf separation to leaf collection is made smoother, reducing material loss and the need for manual operation; using inertia and mechanical transmission to achieve automated leaf collection not only improves work efficiency, but also reduces labor intensity, and promotes the modernization and technological development of agricultural waste treatment.

[0039] See also Figure 3 、 Figure 5 In order to further improve the utilization of plant stem resources, a stem processing module 5 is added to divide the stem into two parts: the epidermis and the inner stem, and the inner stem is recycled as follows:

[0040] The stem and leaf processing equipment includes a stem processing module 5, which is arranged between the stem recovery module 4 and the plant recovery module 1; the stem processing module 5 is composed of the epidermis processing component 51, and the epidermis processing component 51 is used to cut the epidermis of the plant stem to divide the plant stem into the epidermis and the inner stem; the epidermis processing component 51 is composed of a conveying component 511 and an epidermis cutting component 512, and the conveying component 511 and the epidermis cutting component 512 are arranged relative to each other, and the conveying component 511 is provided with spikes 5111 arranged at equal distances, and the spikes 5111 are used to The placement and fixation of the plant stem; the epidermis cutting component 512 is used to clean the epidermis on one side of the plant stem; after the spike 5111 completes the fixation of the plant stem, the plant stem is transported by the conveying component 511, and the stem epidermis is cleaned when passing through the epidermis cutting component 512, completing the cleaning of the single-sided epidermis of the plant stem; the epidermis processing component 51 includes a first epidermis processing component 52, a second epidermis processing component 53, a third epidermis processing component 54 and a fourth epidermis processing component 55 for cleaning the epidermis on different sides of the plant stem, each processing component is responsible for cleaning the epidermis on a different side. The plant stem passes through the first epidermis processing component 52, the second epidermis processing component 53, the third epidermis processing component 54 and the fourth epidermis processing component 55 in sequence to complete the comprehensive epidermis cleaning of the plant stem.

[0041] When processing discarded pineapple plants, the plants are divided into four parts: leaves, inner stems, epidermis and roots, and the leaves and inner stems are selectively recovered. The reason is: although in theory the epidermis can also be used to a certain extent, such as composting, its hard texture and the possibility of containing impurities that are not conducive to subsequent processing (such as a waxy layer) make direct use of it more expensive and less efficient. The roots are usually left in the field to degrade naturally and used as soil conditioners to help maintain soil structure and increase soil organic matter content. If the roots are forcibly recovered, additional mechanical operations and processing steps are required, which increases costs without necessarily bringing corresponding economic benefits.

[0042] See also Figure 8 The epidermis cutting assembly 512 is composed of a rotating frame 5121 and a cutter 5122 arranged on the rotating frame 5121. The rotation axis of the rotating frame 5121 is parallel to the rotation axis of the conveying assembly 511, ensuring that during operation, the rotating frame 5121 can process the plant stem fixed on the conveying assembly 511 in a stable manner. The rotating frame 5121 is arranged in the middle with low ends, and the cutter 5122 is evenly arranged on the surface of the rotating frame 5121, which helps to form an arc-shaped cutting trajectory during rotation, making the cutting more uniform and effectively covering different areas of the stem surface. When the rotating frame 5121 rotates, it drives the cutter 5122 to perform arc-shaped cutting on the epidermis of the plant stem.

[0043] See also Figure 7 The epidermis processing component 51 is provided with a mounting frame 56 for mounting the conveying component 511 and the epidermis cutting component 512; it ensures that the various components can be firmly integrated together, and the position or angle can be adjusted as needed. The conveying component 511 includes a transmission gear 5112 and a transmission member 5113 provided on the mounting frame 56, ensuring that the plant stem fixed on the conveying component 511 can move smoothly. A transmission chain 5114 is provided on the transmission gear 5112, and the transmission member 5113 is slidingly provided on the mounting frame 56. A reset spring 5115 is provided between the transmission member 5113 and the mounting frame 56. The function of the reset spring 5115 is to ensure that the transmission member 5113 can automatically return to the initial position after completing one operation, so as to prepare for the next operation. In addition, it can also provide the necessary pressure to ensure that the stem is firmly fixed on the conveying component 511, thereby improving the cutting accuracy. The transmission member 5113 is provided with a rolling member 5116 acting on the transmission chain 5114. The rolling member 5116 helps to reduce friction, making the transmission smoother, and can adjust the pressure on the stem to ensure its stable transmission while avoiding damage.

[0044] See also Figure 3A stem conveyor belt 41 is provided between the stem processing module 5 and the plant recovery module 1, and the stem conveyor belt 41 is used to move the plant stems from the discharge end of the plant recovery module 1 to the feed end of the stem processing module 5; guide plates 42 are provided on both sides of the stem conveyor belt 41 to ensure that the growth direction of the plant stems is parallel to the transmission direction of the stem conveyor belt 41; and to prevent the stems from deviating from the track or getting entangled during the transmission process, thereby ensuring the smooth progress of subsequent processing steps.

[0045] See also Figure 6 , the first epidermis processing component 52 is the lower epidermis processing component 51, and the feed end of the stem processing module 5 is provided with a feed piece 57, and the action surface of the feed piece 57 and the transmission surface of the stem conveyor belt 41 are on the same horizontal plane, so that the spikes 5111 of the first epidermis processing component 52 can fix the plant stem; ensuring that the plant stem can smoothly transition into the stem processing module 5, reducing the jam or damage caused by the height difference. Specifically, when the plant stem reaches the first epidermis processing component 52 (i.e., the lower epidermis processing component 51), it is fixed by the spikes 5111. The spikes 5111 are evenly distributed on the conveying component 511 to ensure that the stem can be firmly clamped, preparing for the subsequent epidermis cleaning.

[0046] See also Figure 5 The epidermis cutting component 512 is provided with a discharge piece 58 at the discharge end of the fourth epidermis processing component 55. The discharge piece 58 is provided near the discharge end of the fourth epidermis processing component 55 and is located on one side of the conveying component 511 in the fourth epidermis processing component 55. The discharge piece 58 is used to limit the movement of the plant stem and allow the spike 5111 to be separated from the plant stem; the stem recovery module 4 includes an inner stem conveyor belt 43 and an inner stem container, and the inner stem conveyor belt 43 is a scraper conveyor belt; the scraper conveyor belt is used to transport irregularly shaped or easily sliding materials, such as the inner stems of plants after processing. The scraper can help to stably move the fallen inner stems from the discharge port of the stem processing module 5 to the inner stem container. When the epidermis of all four sides of the plant stem is cleaned, the discharge piece 58 will temporarily stop the stem from moving forward. Under the action of the discharge piece 58, the inner stem of the plant with the epidermis processed falls from the discharge port of the stem processing module 5 and is then moved to the inner stem container by the inner stem conveyor belt 43.

[0047] Example 2

[0048] This embodiment discloses a self-propelled pineapple waste plant stem and leaf processing device. Compared with the stem and leaf processing device in Example 1, this embodiment optimizes the structural arrangement of the two conveyor belts 11 in Example 1, as follows:

[0049] The two original conveyor belts 11 are clearly divided into a first conveyor belt 11 and a second conveyor belt 11, which not only helps to more accurately control the clamping and transmission process of the plant stems, but also provides a basis for subsequent spacing adjustment. The spacing between the first conveyor belt 11 and the second conveyor belt 11 can be adjusted, so that the equipment can adjust the distance between the conveyor belts 11 according to the different sizes and shapes of the discarded pineapple plants, thereby ensuring the best clamping effect and transmission efficiency. Through the spacing adjustment mechanism, precise adjustments can be made for plant stems of different diameters to ensure that each plant can be firmly clamped, avoiding unstable clamping or damage caused by differences in plant size; at the same time, appropriate spacing adjustment can effectively reduce the sliding or offset of plants during transportation, ensuring the accuracy of subsequent cutting, separation and other operations.

[0050] Example 3

[0051] This embodiment discloses a self-propelled pineapple waste plant stem and leaf processing device. Compared with the stem and leaf processing device in Example 1, this embodiment replaces the transmission member 5113 used for tensioning and adjusting the transmission chain 5114 in Example 1 with the following:

[0052] The epidermal treatment component 51 is equipped with a tensioning mechanism for controlling the tension of the transmission chain 5114. This tensioning mechanism includes a transmission member 5113, which is equipped with a rolling member 5116 that contacts the transmission chain 5114. The rolling member 5116 guides the movement of the transmission chain 5114, reducing friction and preventing the chain from deflecting or getting stuck during operation. By controlling the position of the transmission member 5113, the tension of the transmission chain 5114 can be controlled, adjusting the tightness of the transmission chain 5114 to ensure that it maintains the appropriate tension. The transmission member 5113 is mounted on a shock-absorbing rod, which prevents the transmission chain 5114 from falling off during plant stem epidermal cleaning. The shock-absorbing rod's primary function is to absorb vibration and impact generated by the transmission chain 5114 during operation, preventing the chain from falling off or being damaged due to excessive vibration. The shock-absorbing rod is typically equipped with a spring or other elastic element to buffer external forces to maintain system stability.

[0053] The transmission member 5113 is located on the inner side of the transmission chain 5114. The transmission members 5113 are respectively the first transmission member 5113 and the second transmission member 5113. The first transmission member 5113 and the second transmission member 5113 act on the transmission chain on both sides respectively. The first transmission member 5113, the second transmission member 5113 and the epidermal cutting assembly 512 belong to the same straight line, and the straight line is parallel to the conveying direction of the conveying assembly 511. The double-sided adjustment design ensures that the transmission chain 5114 always remains balanced during operation, avoiding the situation of being too loose or too tight after adjustment. The first transmission member 5113 and the second transmission member 5113 are both arranged at one end of the shock absorber rod, and a control member is arranged at the other end of the shock absorber rod. The first transmission member 5113 is close to the epidermal cutting assembly 512, and the control member controls the distance between the first transmission member 5113 and the epidermal cutting assembly 512 to achieve control of the amount of epidermal cutting of the plant stem. Combined with sensors and a control system, the spacing can be automatically adjusted to suit the different diameters and shapes of pineapple stems, ensuring optimal cutting results every time. For example, for thicker stems, the spacing can be increased to reduce the amount of cutting; for thinner stems, the spacing can be decreased to increase the amount of cutting.

[0054] Example 4

[0055] This embodiment discloses a self-propelled pineapple waste plant stem and leaf processing device. Compared with the stem and leaf processing device in Example 1, this embodiment optimizes the arrangement of the feed member 57 and the discharge member 58 in Example 1, as follows:

[0056] The feed piece 57 is used to limit the movement of the plant stem, ensuring that the spike 5111 can be accurately inserted into and fixed to the plant stem; the discharge piece 58 is used to limit the movement of the plant stem, ensuring that the spike 5111 can be safely separated from the plant stem. The design of the feed piece 57 and the discharge piece 58 effectively limits the movement of the plant stem during processing, ensuring that the spike 5111 can be accurately inserted and separated, and improving the stability and reliability of the entire system; through precise clamping and fixation, the accuracy of the cutting process is ensured, and the risk of uneven cutting or damage to internal fibers caused by movement of the stem is reduced.
