Description

Technical Field

[0001] This application relates to the technical field of peanut harvesting equipment, specifically a novel integrated device for peanut harvesting. Background Technology

[0002] Peanut harvesting generally falls into two categories: manual harvesting and machine harvesting. Due to advancements in technology and mechanization, most peanut harvesting now relies on machines. During harvesting, since peanuts grow in the soil with their vines and leaves remaining above ground, the peanuts, along with the vines and leaves, are typically dug out of the soil. Large-scale harvesting equipment is often more efficient. However, in hilly and mountainous provinces like Sichuan, Hunan, and Guangdong in southern China, where peanut cultivation is often located in hilly areas, large-scale machine harvesting is difficult. In these cases, manual harvesting or small-scale harvesters are generally used. After harvesting, the peanuts and vines / leaves need to be separated.

[0003] In existing technologies, peanut harvesting and separation are divided into manual and mechanical methods. Manual separation often requires grasping the peanut vines and leaves and slamming the peanuts against the ground to shake them off. Mechanical equipment, such as the semi-automatic peanut vine remover described in Chinese utility model patent CN211482034U, uses a rotating roller structure to knock the peanuts off, while the vines and leaves are pressed and positioned by an upper pressing component to separate them from the peanuts. However, the vertically arranged roller structure may pull peanuts and vines into it. Furthermore, when the rollers rotate, leaves or stalks inevitably fall into them, and these leaves tend to adhere to the surface, affecting subsequent use. Moreover, the pressing structure requires frequent opening and closing to hold the peanut vines. Not only is it easy for peanut vines and leaves to slip into the lower rollers when the lid is opened, but the pressing component may also cause peanuts to be rolled into the lower rollers while the pressing component is stationary.

[0004] Therefore, existing technologies need further improvement and enhancement. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of the existing technology and solve the technical problems mentioned in the background art.

[0006] This utility model provides a novel integrated device for peanut harvesting, including an outer shell, and a knocking component, a suspension component, and a screening component disposed within the outer shell. The knocking component includes a horizontally rotating knocking disc, the suspension component includes a rotatable vertical cantilever, the vertical cantilever is positioned above the edge of the knocking disc and in the opposite direction of rotation to the knocking disc, and the screening component is positioned below the knocking disc and includes multiple layers of screens.

[0007] In a preferred embodiment of this application, a plurality of flexible rods are evenly spaced on the outer side of the dropping disc, and a vertical cantilever is positioned directly opposite the gap between the flexible rods.

[0008] In a preferred embodiment of this application, the suspension assembly further includes a mounting plate, which is placed on top of the housing and includes an inner plate and an outer plate. The outer plate is connected to the housing, and the inner plate rotates relative to the inner plate.

[0009] In a preferred embodiment of this application, a clamping claw is provided on the side of the vertical cantilever away from the placement plate for clamping peanut vine leaves.

[0010] In a preferred embodiment of this application, a vibration component is provided inside the vertical cantilever and the dropping plate.

[0011] As a preferred embodiment of this application, the multi-layer screen includes a diversion screen and a screening screen, which are arranged in layers from top to bottom and in opposite directions. The diversion screen has multiple hanging points on its surface to block seedling leaves.

[0012] As a preferred embodiment of this application, the multi-layer screen includes a diversion screen and a screening screen, which are arranged in layers from top to bottom and in opposite directions. A fan is provided at the edge of the screening screen to blow air onto the diversion screen, and a storage box is provided on the inner side wall of the outer shell corresponding to the direction of the fan.

[0013] The beneficial effects of this application are as follows:

[0014] This application, by setting a horizontal striking disc structure, differs from the commonly used vertically arranged relatively rotating rollers in the prior art. Firstly, this structure only requires driving one horizontal striking disc, resulting in a very simple transmission system, meaning lower manufacturing costs and lower power consumption. Secondly, compared to the prior art's two relatively rotating roller structures, which primarily separate peanuts from stalks through squeezing and striking, the horizontal striking disc structure in this application applies force to the pods for a very short time, tending to break the pods from the stalks rather than crushing them. This improves the quality of peanut harvesting and greatly reduces the risk of peanuts being crushed or broken. Furthermore, because the horizontal striking disc structure in this application primarily contacts the peanuts intermittently, the striking action relies not only on the striking disc but also on the peanut's own gravity, resulting in a larger gap and reducing the likelihood of entanglement.

[0020] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0023] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0025] like Figures 1 to 3 As shown, this application provides a novel integrated device for peanut harvesting, including an outer shell 1, and a knocking component 2, a suspension component 3, and a screening component disposed within the outer shell 1. The knocking component 2 includes a horizontally rotating knocking disc 21, and the suspension component 3 includes a rotatably mounted vertical cantilever 31. The vertical cantilever 31 is positioned above the edge of the knocking disc 21 and rotates in the opposite direction to the knocking disc 21. The screening component is positioned below the knocking disc 21 and includes multiple layers of screens 4.

[0026] Among them, such as Figure 1 As shown, the outer casing 1 adopts a cylindrical structure to facilitate the rotation of the suspension assembly 3 and the drop-off assembly 2; the drop-off disc 21 can adopt a circular disc structure, with a rotating motor installed on its top to drive the drop-off disc 21 to rotate horizontally; for the vertical cantilever 31, as shown... Figure 1 As shown, an electric lifting rod structure can be used to adjust the height of the vertical cantilever 31 to match different harvested peanut vine and leaf lengths.

[0027] Furthermore, multiple flexible rods 22 are evenly spaced on the outer side of the drop plate 21, and the vertical cantilever 31 is directly opposite the gap between the flexible rods 22.

[0028] It is understandable that, for the structure of flexible rod 22, such as Figure 1 As shown, a structure with a slightly curved angle can be adopted, so that the rotated flexible rod 22 exhibits a swinging motion, improving the effect of knocking down the peanuts while reducing the crushing effect. Its material can be rubber, which can reduce damage to the peanut shells.

[0029] Optionally, in order to improve the knocking effect during peanut harvesting, a protruding arc-shaped groove can be provided on the inner wall of the outer shell 1 near the knocking disc 21. This allows the peanuts to be thrown into the arc-shaped groove for a secondary impact during the rotation of the vertical cantilever 31 and the knocking disc 21. Compared with direct compression, this reduces damage to the peanut shells and also improves the separation effect between the peanuts and the vines.

[0030] As a preferred embodiment of this application, such as Figure 2 As shown, the suspension assembly 3 also includes a mounting plate, which is placed on top of the housing 1. The mounting plate includes an inner plate 32 and an outer plate 33. The outer plate 33 is connected to the housing 1, and the inner plate 32 rotates relative to the inner plate 32.

[0031] Understandably, for the 33 structure of the outer plate, such as Figure 2 As shown, it is similar to a support structure. The bottom is connected to the edge of the outer shell 1, and the top is set with a horizontal outer plate 33 structure. A motor is set at the top center of the outer plate 33 structure and connected to the inner plate 32 structure inside the outer plate 33 to realize the rotation of the inner plate 32. The lower part of the inner plate 32 is detachably connected to a vertical cantilever 31, which is used to clamp the peanut vines and leaves, so that the peanut fruit can penetrate into the outer shell 1.

[0032] In addition, a protruding ring structure can be provided at the bottom of the inner plate 32 to facilitate connection with the vertical cantilever 31. Furthermore, since the outer plate 33 is a stationary structure and the center of the bottom wall of the outer plate 33 is not connected to the inner plate 32, it can be used as the placement position for the motor of the lower drop plate 21. Placing the motor here will not only avoid conflict with other structures, but also save installation space and make it more convenient to use.

[0033] It is understandable that the integrated equipment mentioned in this application is mainly for the integrated harvesting of peanut fruits and vines after peanut harvest. It is also understandable that the existing structures often only collect peanuts during harvest. As for the vines, they can not only be used as livestock feed, but also be processed into fertilizer and have certain medicinal value. Therefore, the vertical cantilever 31 can preserve peanut vines as completely as possible, and integrate the collection of peanut fruits and peanut vines during harvest to avoid waste of resources.

[0034] Furthermore, a clamping claw 34 is provided on the side of the vertical cantilever 31 away from the placement tray to clamp the peanut vines and leaves. The clamping claw 34 can adopt a common clamping structure to grasp the peanut vines and leaves. In order to improve the convenience of harvesting, two or more vertical cantilever 31 structures can be set. Furthermore, a hinge structure can be set between the vertical cantilever 31 and the placement tray. For both sides of the outer shell 1, a vertical storage rack 6 structure can be set. After the peanut fruits are separated, the vertical cantilever 31 can first retract and rise to pull the vines and leaves out of the outer shell 1. Through hinge rotation, the peanut vines and leaves are placed above the storage rack 6. At this time, the clamping claw 34 opens and places the vines and leaves in the storage rack 6, completing the collection of the vines and leaves.

[0035] For the grasping of peanuts and peanut vines, a manual method can be used. The peanut vines are manually placed at the gripper 34, which then grasps the vines and returns to its original position to shake the peanuts off. Of course, automatic control can also be set up. The side wall of the outer shell 1 should also include a harvesting box. The peanuts and vines in the harvesting box need to be manually placed in the same order, and the height of the harvesting box should be close to the surface of the outer shell 1. By manually setting the PLC or microcontroller program, the vertical cantilever 31 can be automatically lowered and drive the gripper 34 to grasp the peanut seedlings, thereby improving the level of automation and intelligence.

[0036] In one alternative implementation, such as Figure 1 As shown, a vibration component 5 is installed inside the vertical cantilever 31 and the knocking disc 21. The vibration component 5 can adopt the simplest vibration motor structure. By setting the vibration motor inside the edge of the knocking disc 21, the flexible rod 22 is driven to resonate. This can improve the knocking effect on peanuts and reduce the occurrence of vines and leaves sticking to the gaps in the flexible rod 22.

[0037] The vibration component 5 installed inside the vertical cantilever 31 can be set at the connection of the clamping claw 34. Its effect is similar to the structure in the knocking disc 21. When knocking down peanuts, the vibration of the vibration component 5 can cause the peanuts and peanut seedlings to resonate, thereby improving the knocking effect of peanuts and improving harvesting efficiency.

[0038] Optionally, the multi-layer screen 4 includes a diversion screen 41 and a screening screen 42, which are arranged in layers from top to bottom and in opposite directions. The diversion screen 41 has multiple hanging points 43 on its surface to block the seedling leaves.

[0039] In this embodiment, the main function of the diversion net 41 is to reduce the amount of vine leaves mixed in during the collection of peanuts below. For the multiple hanging points 43 of the diversion net 41, an arc-shaped hook structure can be adopted, with the arc-shaped opening facing the direction from which the peanuts roll. Since the peanuts themselves have a relatively hard shell, during the rolling process, they will be diverted or collided at the hanging points 43, thus avoiding the hanging points 43 and being transported downwards normally. The seedlings, on the other hand, are relatively soft and may have long stems and leaves remaining, so they have a greater chance of being captured by the hanging points 43, realizing the collection of residual seedling leaves, thereby improving the harvest integration effect.

[0040] In another embodiment, the multi-layer screen 4 includes a diversion screen 41 and a screening screen 42, which are arranged in layers from top to bottom and in opposite directions. A fan is provided at the edge of the screening screen 42 to blow air onto the diversion screen 41, and a storage box is provided on the inner side wall of the outer casing 1 corresponding to the direction of the fan.

[0041] It is understood that in this embodiment, the diversion net 41 can refer to the structure in the previous embodiment. The difference is that the edge of the screening net 42 is provided with a fan structure, which can blow air onto the surface of the diversion net 41. On the one hand, the soil remaining on the diversion net 41 can be blown up to a certain extent and blown into the storage box in the corresponding direction. On the other hand, the blade structure remaining on the surface of the diversion net 41 can also be blown into the storage box with the airflow.

[0042] Of course, the two embodiments described above are merely optional implementations of this application. These structures are provided to improve the functionality of this application, and not providing these structures will not affect the basic functionality of this solution.

[0043] Specifically, in use, the vertical cantilever 31 first clamps the harvested peanuts with vines and leaves, allowing the peanuts to penetrate deep into the outer shell 1. The peanuts are then knocked off by the knocking disc 21. After knocking for a period of time, the vertical cantilever 31 rises, and the vibration component 5 begins to vibrate, ensuring that the peanuts are shaken off as much as possible. At this point, the peanuts and vines and leaves have separated. The vertical cantilever 31 then shortens and rotates, placing the vines and leaves on the storage rack 6, thus achieving integrated harvesting of the peanuts and vines and leaves and improving the harvesting effect.
