Abstract
Description
A crop removal machine Technical Field
[0001] The invention belongs to the technical field of crop processing, and in particular relates to a crop stem removing machine. Background Art
[0002] The processing of crops has become mechanized, and the processing needs of different types of crops are becoming more and more diverse. Taking the removal of stems of dried peppers as an example, the traditional way of removing the stems is to remove them manually, which is time-consuming and labor-intensive. There are also some machines on the market that can remove the stems of straight-handled peppers. Their working method is to put the peppers to be processed into a drum with small holes in the side wall. During the rolling of the drum, the straight stems of the peppers are exposed through the small holes, and the cutter set on the outside of the drum cuts off the straight stems when the drum rolls. This machine can only process straight-handled peppers, and cannot remove the stems of curved-handled peppers. Similarly, for other curved-handled crops that need to be processed, there is no machine in the prior art that can automatically remove the stems. Therefore, it is necessary to design a machine for removing the stems of curved-handled crops to solve the problems in the prior art.
[0003] Summary of the Invention
[0004] The purpose of the present invention is to provide a crop stem removing machine to solve the problem that the stems of crops with bent stems cannot be automatically removed.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:
[0006] A crop harvester includes a motor, a bracket and a rotating cage. The rotating cage is long and cylindrical and has a cage wall. The rotating cage is installed on the bracket in a horizontal position. The motor drives the rotating cage to rotate around the center. The machine also includes a cutting band saw device. The cutting band saw device includes a saw wheel and a band saw blade. The two saw wheels of the cutting band saw device are respectively arranged at both ends of the bracket. The saw wheel tensions the band saw blade. The teeth of the band saw blade are opposite to the rotation direction of the rotating cage. The band saw blade circulates along the length direction of the rotating cage. A plurality of rigid suspension lines arranged along the length direction of the rotating cage are provided in the rotating cage. The band saw blade is parallel to the rigid suspension line. The radial distance from the rigid suspension line to the center of the rotating cage is greater than the radial distance from the band saw blade to the center of the rotating cage.
[0007] Furthermore, the band saw blade is arranged at the upper part of the cage space.
[0008] Furthermore, the direction in which the teeth of the band saw blade rotate toward the rotating cage is forward, and a positioning bar is provided in front of the teeth of the band saw blade, and at least one side of the positioning bar has a plurality of V-shaped guide grooves.
[0009] Furthermore, the difference between the radial distance from the rigid suspension line to the center of the rotating cage and the radial distance from the band saw blade to the center of the rotating cage is between 0.1 cm and 10 cm.
[0010] Furthermore, the cage wall of the rotating cage has a through hole, and one end of the rotating cage is provided with a discharge port.
[0011] Furthermore, the rotating cage is inclined at an angle to the ground along its rotation axis.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0022] Example 1
[0023] Referring to Figures 1 and 2, this embodiment provides a crop destemming machine, comprising a motor 1, a support 2, and a rotating cage 3. The rotating cage 3 is elongated and cylindrical, having a cage wall. The rotating cage 3 is mounted on the support 2 in a horizontal position. The motor 1 drives the rotating cage 3 to rotate about its center. The machine also includes a cutting band saw device, which includes a saw wheel and a band saw blade 5. The two saw wheels of the cutting band saw device are respectively disposed at both ends of the support 1. The band saw blade 5 is disposed in the upper portion of the rotating cage space. The saw wheel tensions the band saw blade 5, with the teeth of the band saw blade 5 facing in the opposite direction of the rotation of the rotating cage 3. The band saw blade 5 circulates along the length of the rotating cage 3. A plurality of rigid suspension wires 4 are provided within the rotating cage 3 along the length of the rotating cage 3. The band saw blades 5 are parallel to the rigid suspension wires 4, and the radial distance from the rigid suspension wires 4 to the center of the rotating cage 3 is greater than the radial distance from the band saw blades 5 to the center of the rotating cage 3. The rigid suspension wires 4 are preferably steel wire ropes, but may also be made of other rigid materials with less elasticity.
[0024] Specifically, a sliding track is provided on the outer periphery of the sidewall of cage 3. A rotating wheel is mounted on bracket 2 and contacts the sliding track. Motor 1 drives the rotating wheel, which in turn, via the sliding track, drives cage 3 around its center. The elongated cylindrical cage 3 has a feed inlet and a discharge outlet at either end. Cage 3 is tilted along its axis of rotation to the ground, with the feed inlet slightly higher than the discharge outlet, facilitating the forward movement of materials along the tilted angle.
[0025] In this embodiment, there are two cutting band saw devices, and the two band saw blades of the two cutting band saw devices are arranged in parallel, which facilitates the sequential severing of the curved peppers. In this embodiment, the cage wall of the rotating cage 3 has through holes, that is, the top and bottom ends of the long cylindrical rotating cage 3 are hollow, and its side walls are in the form of a screen with through holes.
[0026] Furthermore, the difference between the radial distance between the suspension wire 4 and the center of the rotating cage 3 and the radial distance between the band saw blade 5 and the center of the rotating cage 3 is between 0.1 cm and 10 cm, facilitating the cutting of curved handlebars. The teeth of the band saw blade 5 rotate forward toward the rotating cage 3. A positioning bar 8 is provided in front of the teeth of the band saw blade 5. The positioning bar 8 has multiple V-shaped guide grooves on at least one side. The V-shaped guide grooves are used to position the curved handlebar to be cut at the bottom of the V-shape, facilitating rapid cutting of the handlebar.
[0027] Example 2
[0028] 3 , the rotating cage 3 can also be made of a strip profile, and baffles 7 are provided on the left and right sides and front and rear ends of the lower portion of the rotating cage 3. The space formed by the baffles 7 on the left and right sides and front and rear ends of the lower portion of the rotating cage 3 is used to accommodate the crops to be processed.
[0029] Here, the baffle 7 has a sieve hole at the bottom for leaking the waste to the waste conveyor belt 6. The waste conveyor belt 6 is arranged just below the outside of the rotating cage 3, and the waste conveyor belt 6 is driven along the axial direction of the rotating cage 3.
[0030] In the above two embodiments, the rotation of the saw wheel and the transmission of the waste conveyor belt 6 are driven by motors respectively. Since the motor setting and driving method are existing technologies, they are not described in detail in the present invention.
[0031] The working principle of the crop removal machine provided by the present invention is:
[0032] Crops with curved handles to be processed are placed in the rotating cage 3. As the cage 3 rotates, the curved crops are hooked by the hanging wires 4 and rotate with the cage 3. When the crops reach the top of the cage 3 and approach the positioning bar 8, the curved portion of the crops is caught in the V-shaped guide groove of the positioning bar 8. Simultaneously, the crops are cut by the band saw blades 5. The cut crops return to the mesh-formed cage 3 or the space accommodated by the baffle 7 and are gravity-fed along the inclined angle of the cage 3 toward the discharge port. After cutting, the remaining residue on the hanging wires 4 is carried back to the bottom of the cage 3 as the cage 3 rotates, leaks through the mesh holes of the baffle 9, and is discharged via the waste conveyor belt 6.
[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
