Description

Technical Field

[0001] This invention relates to the field of pepper harvesting equipment technology, and in particular to an active feeding pepper harvesting device. Background Technology

[0002] Sichuan pepper fruits are distributed irregularly in all directions along the branches, which are covered with sharp thorns that are easily damaged. For a long time, manual harvesting has been the primary method of Sichuan pepper harvesting. However, manual harvesting is inefficient, time-consuming, prone to injury from thorns, labor-intensive, and costly, significantly impacting farmers' economic benefits. Existing harvesting machinery mainly relies on manual harvesting tools to locate the specific position of the pepper fruit stalk, resulting in low harvesting rates. Traditional manual harvesting methods can no longer meet the needs of the Sichuan pepper industry, making the demand for efficient Sichuan pepper harvesting machinery urgent. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an active feeding pepper harvesting device to solve problems such as low harvesting efficiency, easy hand injury, and high labor intensity. This invention designs an active feeding pepper harvesting device, driven by a motor. The active feeding device and cutting device of the harvesting system work together to quickly and actively feed and cut the peppers. Then, the differential speed comb-tooth threshing device of the harvesting system threshes the cut peppers and carries them into the rear collection channel. The harvesting process can be operated with one hand, eliminating the need for precise positioning of the pepper stalk root, effectively shortening harvesting time, improving harvesting efficiency, reducing labor intensity, and avoiding problems such as hand injury.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An active feeding type pepper harvesting device includes a shell, a harvesting system, and an upper fixed plate; the upper fixed plate is connected to a connecting surface on the upper part of the shell; the harvesting system includes a cutting device, an active feeding device, and a drive mechanism; the active feeding device is located at the front end inside the shell and includes a spiral feeding mechanism; the spiral feeding mechanism includes a pair of spiral rollers a and b with equal rotation speed, opposite direction, and parallel axes, the upper parts of the two spiral rollers are respectively connected to the upper fixed plate, and the lower parts pass through the partition plate of the shell and are connected to the lower drive mechanism; the outer surface of the spiral roller b... The surface has a right-handed spiral structure, except that the spiral structure of the spiral roller a is left-handed; the rotation direction of the spiral roller a is clockwise when viewed from above; the cutting device is located at the lower front of the housing and in front of the active feeding device. The angle between the cutting surface of the cutting device and the plane formed by the axes of the two spiral rollers is in the range of -10° to +10°, and the distance from two points at the same height on the axes of the two spiral rollers to the cutting surface is equal. The cutting device includes a fixed plate and a cutting mechanism. The upper part of the fixed plate has a V-shaped cut, and the cutting mechanism is located at the lower part of the V-shaped cut.

[0005] The spiral structure on the outer surface of the spiral roller b has an arc-shaped top. The spiral structure becomes straight and downward at the lower part of the roller body near the shell, and there is an inclined surface between the spiral structure and the roller body to avoid the formation of an angle between the spiral structure and the body, which would cause the pepper fruits to be squeezed and entangled. The spiral roller a has the same structure as the spiral roller b except that the spiral structure is a left-handed spiral. The surfaces of both the spiral roller a and the spiral roller b in the middle part of the upper fixed plate and the partition plate are covered with soft material to protect the pepper fruits from damage.

[0006] The active feeding device also includes an automatic adjustment mechanism connected to the upper and lower parts of the spiral feeding mechanism, which automatically adjusts the distance between the two spiral rollers to vary with the size of the pepper fruits of different varieties and growth stages, thus avoiding damage to the pepper fruits due to compression. The automatic adjustment mechanism includes an upper connector, a lower connector, and springs. One end of the upper connector is connected to the upper part of the spiral roller a via a bearing, and the other end rotates around its rotation center a. One end of the lower connector is connected to the lower part of the spiral roller a, and the other end rotates around its rotation center b, which is coaxial with the rotation center a. Two springs connect the two rollers at the top and bottom respectively, and provide tension.

[0007] The harvesting system also includes a differential comb threshing device located at the rear end inside the housing. It includes two comb teeth, a and b, with different rotation speeds, opposite directions, and parallel axes. The upper parts of comb teeth a and b are connected to the fixed base and thus fixed to the housing, while the lower parts pass through the partition plate of the housing and are connected to the lower drive mechanism. The rotation direction of comb tooth a is clockwise when viewed from above. The different rotation speeds of the two comb teeth create a shearing action between the teeth, thereby threshing the peppercorns.

[0008] The differential speed comb threshing device includes a rotating shaft a at the center of rotation and multiple tooth layers a at equal vertical spacing. Each tooth layer has several teeth a evenly distributed, and each tooth layer a has an annular anti-winding mechanism a near the rotating shaft a to prevent peppercorns from getting tangled on the comb teeth. The teeth a are arc-shaped, and all teeth a are arranged in a spiral on the rotating shaft a. The comb b includes a rotating shaft b at the center of rotation and multiple tooth layers b at equal vertical spacing. Each tooth layer b has several teeth b evenly distributed, and each tooth layer b has an annular anti-winding mechanism b near the rotating shaft b. Each tooth layer of the comb teeth a and b is staggered and distributed at equal intervals. The distal ends of the teeth of two comb teeth are close to the axis of the other comb tooth, and the tooth tips reach the annular range of the annular anti-winding mechanism. The surfaces of the comb teeth a and b located in the middle area between the lower part of the fixed base and the partition plate of the housing are covered with soft material to prevent damage to the peppercorns from collision.

[0009] The differential speed comb threshing device has several horizontally arranged teeth on its comb b, so that each tooth b forms a comb-like structure. During threshing, the comb-like structure clamps and fixes the pepper fruits, which is beneficial to completing the threshing.

[0010] The drive mechanism includes a drive motor providing power, a roller gear b, a motor gear a, a transmission gear a, a rotating gear a, a rotating gear b, a transmission gear b, and a roller gear a. The roller gear b is connected to the lower part of the spiral roller b and meshes with the motor gear a fixed on the drive motor shaft, thus rotating the spiral roller b. The roller gear a is connected to the lower part of the spiral roller a. The transmission gear b is fixed on the lower connecting member, and the rotating gear b is coaxial with the rotation center b of the lower connecting member. The motor gear a, transmission gear a, rotating gear b, and transmission gear b... Roller gears a mesh sequentially to rotate the spiral roller a; roller gears b and roller gears a are staggered and do not mesh, but rotate at the same speed and in opposite directions; rotating gear b is fixed to the lower part of comb teeth a, and transmission gear a rotates around comb teeth b. Motor gear a, transmission gear a, and rotating gear b, fixed to the drive motor shaft, mesh sequentially to rotate comb teeth b. Motor gear b and rotating gear a, fixed to the drive motor shaft, mesh to rotate comb teeth a. Transmission gear a and rotating gear a are not connected.

[0011] The housing contains a partition plate that is initially tilted downwards and then horizontally arranged, a handle at the rear, a slot at the top, and a collection channel at the rear. A control switch is also installed to allow for handheld gripping and operation of the harvesting device. The downward tilt of the partition plate facilitates the downward and rearward movement of the peppercorns. The partition plate divides the housing into upper and lower spaces. The upper space houses the active feeding device and the differential comb threshing device, while the lower space houses the drive mechanism. The front of the partition plate has a hole c connecting to the spiral roller b and a hole b connecting to the spiral roller a, while the rear of the partition plate has a hole d connecting to the comb tooth a and a hole a connecting to the comb tooth b.

[0012] The upper fixing plate has a hole f that connects to the upper part of the spiral roller b, a hole e that connects to the upper part of the spiral roller a, and a boss that connects to the slot of the housing, making the upper fixing plate easier and more secure to install.

[0013] The cutting mechanism of the cutting device includes cutting blade a and cutting blade b. It also includes a transmission element, a guide groove, a guide shaft, a drive groove, and a motor. The cutting blade is fixed to the fixed plate by the guide shaft, so that it can only slide along the guide groove and against the fixed plate. The motor drives the cutting blade to move through the transmission element to complete the cutting.

[0014] Compared with the prior art, the beneficial effects of this invention are: 1. This pepper harvesting device is highly integrated, small in size, lightweight, efficient, flexible, and adaptable. This invention can replace manual harvesting, improving harvesting efficiency, reducing hand injuries, and lowering labor intensity compared to existing technologies.

[0015] 2. This invention utilizes the combined action of an active feeding device and a cutting device to quickly harvest Sichuan peppercorns, thereby improving efficiency.

[0016] 3. This invention utilizes the relative rotation of two spiral rollers in the spiral feeding mechanism of the active feeding device. This rotation drives the Sichuan peppercorns to move simultaneously along the tangential and axial directions of the rollers, achieving a downward oblique movement. This enables active and rapid feeding of the Sichuan peppercorns, while simultaneously pushing the root of the peppercorn stalk downwards towards the cutting device, preparing it for rapid cutting. The automatic adjustment mechanism of the active feeding device can automatically adjust the distance between the two spiral rollers to vary according to the different varieties and growth stages of the Sichuan peppercorns, reducing damage to the peppercorns.

[0017] 4. This invention utilizes the vertical structure and inclined surface of the spiral structure at the bottom of the spiral roller to prevent the angle between the spiral structure and the shell from squeezing and damaging the peppercorns, thus avoiding entanglement. The top of the spiral structure is arc-shaped to prevent the spiral structures of the two spiral rollers from forming relatively parallel surfaces that could cause squeezing damage to the peppercorns. The spiral rollers and comb teeth are covered with a soft material to prevent hard contact that could damage the peppercorns.

[0018] 5. This invention utilizes the shearing action generated by the different speeds of the teeth of two relatively rotating combs in a differential speed comb threshing device to thresh peppercorns, facilitating subsequent collection and fruit / leaf sorting. Simultaneously, the two relatively rotating combs carry the peppercorns into the rear collection channel. An annular anti-tangling mechanism on the combs prevents the peppercorns from becoming entangled on the combs. The teeth of the combs are arranged spirally on the rotating shaft, preventing multiple teeth from simultaneously creating a shearing action, thus reducing energy consumption.
