Description

Technical Field

[0001] This invention relates to a chili harvester and harvesting method, belonging to the field of chili harvesting technology. Background Technology

[0002] During the peak fruiting season of chili pepper cultivation, the fruits ripen at a concentrated pace, resulting in a short harvesting cycle and a large workload. Currently, chili pepper harvesting is mainly done manually. While manual harvesting offers advantages such as clean fruit removal and a low rate of fruit loss and damage, it also presents challenges due to high labor intensity and low harvesting efficiency. To improve chili pepper harvesting efficiency, replacing manual labor with chili pepper harvesting machinery has become inevitable.

[0003] The applicant found that the Chinese patent specification with publication number CN101828467A discloses a toothed chili pepper harvester. The toothed rod rotates and uses tangential force to harvest chili peppers and other fruits and vegetables. It can harvest chili peppers quickly and efficiently, but the toothed chili pepper harvester has a high damage rate and produces a lot of dust during harvesting.

[0004] Further searches by the applicant revealed that Chinese patent publication number CN212993121U discloses a small chili harvester with a double-helix structure for its harvesting mechanism. The chili plant enters the middle of the double helix rod through the forward guide plate, and the helix rod rotates from bottom to top and outward to crush the chili. However, the double helix harvesting efficiency is too low, and the chili harvesting period is short, making it difficult to meet production needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a chili harvester and harvesting method that can quickly and efficiently harvest chilies and reduce the damage rate of chilies.

[0006] To solve the above-mentioned technical problems, on the one hand, the present invention proposes a chili harvester, including a clamping and conveying device and a fruit-removing device, both of which are mounted on a frame;

[0007] The clamping and conveying device includes a primary clamping and conveying mechanism and a secondary clamping and conveying mechanism arranged in sequence. The primary clamping and conveying mechanism includes two parallel synchronous belts, and the secondary clamping and conveying mechanism includes two parallel chains. Clamping plates are fixed to the chain links. The secondary clamping and conveying mechanism is located above the primary clamping and conveying mechanism, and a cutting disc is provided below the primary clamping and conveying mechanism.

[0008] The fruit stripping device includes a fruit stripping roller and a cover that matches the fruit stripping roller. The axial direction of the fruit stripping roller is consistent with the conveying direction of the secondary clamping and conveying mechanism. Both the fruit stripping roller and the cover are located above the secondary clamping and conveying mechanism and correspond one-to-one with the two chains. The side of the cover facing the fruit stripping roller is a vertical plane, and an arched protrusion is provided on the vertical plane.

[0009] On the other hand, the present invention also proposes a chili harvesting method, including the following steps: the chili harvester is attached to a power unit, and the chili plants are aligned with the positions of the primary clamping and conveying mechanism; the chili harvester moves so that the primary clamping and conveying mechanism clamps the chili plants, and the cutting disc cuts the roots of the chili plants along the ground. The cut chili plants move backward along the center line of the primary clamping and conveying mechanism. When they reach the secondary conveying mechanism, the secondary conveying mechanism uses a clamping plate to clamp the main stem of the chili plants and then moves further backward. When the chili plants move to the working area of ​​the fruit-removing device, fruit removal is performed. At this time, the arched protrusions on the vertical plane of the cover squeeze the chili plants toward one side of the fruit-removing roller. The chili peppers are peeled off the chili plants by the squeezing of the fruit-removing roller and the arched protrusions, thereby completing the fruit removal.

[0010] In use, this invention first severs the roots of the chili pepper plant using the cutting disc. Then, the main stem of the plant is clamped, and the chili peppers are peeled from the plant by the pressure exerted by the peeling roller and the arched protrusions on the vertical plane of the cover. This invention, by using the pressure of the peeling roller and the arched protrusions to peel the chili peppers from the plant, significantly improves harvesting efficiency compared to double-helix harvesting. Compared to toothed chili pepper harvesters, it eliminates the need for tangential force during the rotation of the toothed rod, thus effectively reducing the damage rate of the chili peppers.

[0019] Example 1

[0020] This embodiment relates to a chili harvester, such as... Figure 1 , Figure 2 and Figure 6 As shown, it includes a clamping and conveying device and a fruit-removing device, both of which are mounted on the frame 1.

[0021] The clamping and conveying device includes a primary clamping and conveying mechanism and a secondary clamping and conveying mechanism arranged sequentially. The primary clamping and conveying mechanism includes two parallel synchronous belts 6, with a gap between the two synchronous belts 6 for clamping the chili plant 7. The secondary clamping and conveying mechanism includes two parallel chains 8, with clamping plates 8-1 (e.g., clamping plates 8-1) fixed to the links of the chains 8. Figure 3 As shown), the gap between the two chains 8 is used to clamp the chili plant 7; preferably, the outer surface of the clamping plate 8-1 is provided with serrated teeth (such as...). Figure 5 As shown in the figure, this can improve the clamping effect.

[0022] like Figure 2 As shown, the secondary clamping and conveying mechanism is located above the primary clamping and conveying mechanism. The primary clamping and conveying mechanism is used to clamp the lower middle part of the main stem of the chili plant 7, and the secondary clamping and conveying mechanism is used to clamp the upper middle part of the main stem of the chili plant 7. A cutting disc 5 is provided below the primary clamping and conveying mechanism. The cutting disc 5 cuts the chili plant 7 from the root of the chili plant 7.

[0023] like Figure 1 As shown, the fruit-removing device includes a fruit-removing roller 3 and a cover 4 that matches the fruit-removing roller 3. The axial direction of the fruit-removing roller 3 is consistent with the conveying direction of the secondary clamping and conveying mechanism. Both the fruit-removing roller 3 and the cover 4 are located above the secondary clamping and conveying mechanism and correspond one-to-one with the two chains 8. Figure 4 As shown, the side of the cover 4 facing the fruit-removing roller 3 is a vertical plane 4-1, and an arched protrusion 4-2 is provided on the vertical plane 4-1. Preferably, the surface of the fruit-removing roller 3 is provided with several hump-shaped teeth, which can harvest peppers more efficiently.

[0024] To facilitate the collection of harvested chili peppers, the preferred variety is, for example... Figure 1As shown, a fruit conveyor belt 2 is provided on the side of the cover 4 away from the fruit-removing roller 3. The cover 4 has an arc-shaped surface 4-3 extending from the vertical plane 4-1 to the fruit conveyor belt 2. The fruit-removing roller 3 drives the harvested peppers upward and conveys them along the arc-shaped surface 4-3 of the cover 4 to the fruit conveyor belt 2, which then transports the peppers to the next process. Preferably, the cross-section of the cover 4 is fan-shaped.

[0025] This embodiment can also be improved in the following ways: 1) such as Figure 1 As shown, there are two fruit-removing devices. The fruit-removing rollers 3 and covers 4 of the two devices are in opposite positions. Assuming the two devices are fruit-removing device A and fruit-removing device B, the fruit-removing roller 3 of device A and the cover 4 of device B are located above one chain 8, and the fruit-removing roller 3 of device B and the cover 4 of device A are located above another chain 8. In this way, when the chili pepper plant 7 passes through fruit-removing device A, the peppers on one side of the plant 7 are harvested, and when it passes through fruit-removing device B, the peppers on the other side are harvested. The fruit-removing principle is exactly the same in both devices. By reversing the fruit-removing direction, rapid harvesting of chili peppers is achieved, further improving harvesting efficiency.

[0026] Example 2

[0027] This embodiment relates to a chili harvesting method using the method described in Embodiment 1, including the following steps:

[0028] The chili harvester is attached to the power unit. First, the rows are aligned so that the chili plants 7 correspond to the positions of the primary clamping and conveying mechanism. Figure 6 As shown;

[0029] The chili harvester moves, causing the primary clamping and conveying mechanism to clamp the chili plant 7. The cutting disc 5 cuts the root of the chili plant 7 along the ground. The cut chili plant 7 moves backward along the center line of the primary clamping and conveying mechanism. When it moves to the secondary conveying mechanism, the secondary conveying mechanism uses the clamping plate 8-1 to clamp the main stem of the chili plant 7 and then moves further backward. When the chili plant 7 moves to the working area of ​​the fruit-removing device, fruit removal is performed. At this time, the arched protrusion 4-2 of the vertical plane 4-1 of the cover 4 squeezes the chili plant 7 towards one side of the fruit-removing roller 3. The chili is peeled off from the chili plant 7 by the squeezing of the fruit-removing roller 3 and the arched protrusion 4-2, thus completing the fruit removal.

[0030] Preferably, when the cover 4 is provided with a fruit conveyor belt 2 on the side away from the fruit-removing roller 3, the cover 4 has an arc-shaped surface 4-3 extending from the vertical plane 4-1 to the fruit conveyor belt 2; after fruit removal, the peppers peeled from the pepper plant 7 move upward under the rotation of the fruit-removing roller 3 and slide down along the arc-shaped surface 4-3 of the cover 4 onto the fruit conveyor belt 2, and are transported to the designated area by the fruit conveyor belt 2.

[0031] Preferably, when there are two fruit-removing devices, the positions of the fruit-removing rollers 3 and the cover 4 of the two fruit-removing devices are opposite. At this time, there are also two fruit conveyor belts 2. After the secondary conveying mechanism drives the pepper plant 7 into the working area of ​​the first fruit-removing device to complete the fruit removal, it enters the working area of ​​the second fruit-removing device to complete the reversal fruit removal of the pepper plant 7.
