Description

Technical Field

[0001] The utility model 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 the 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. The working method is to put the peppers to be processed into a drum with small holes on 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 for curved-handled peppers, the stems cannot be removed. 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. Utility Model Content

The rotating cage is installed on the support in a horizontal direction. The motor drives the rotating cage to rotate around the center. The machine also comprises a cutting band saw device. The cutting band saw device comprises a saw wheel and a band saw blade. Two saw wheels of the cutting band saw device are respectively arranged at two ends of the support. The saw wheel tensions the band saw blade. The teeth of the band saw blade are oriented 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 arranged 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.

[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] Example 1

[0022] See also Figure 1 to Figure 2The present embodiment provides a crop stem removal machine, including a motor 1, a support 2 and a rotating cage 3. The rotating cage 3 is in the shape of an elongated cylinder and has a cage wall. The rotating cage 3 is installed on the support 2 in a horizontal direction. The motor 1 drives the rotating cage 3 to rotate around the center. The cutting band saw device also includes a saw wheel and a band saw blade 5. The two saw wheels of the cutting band saw device are respectively arranged at the two ends of the support 1. The band saw blade 5 is arranged at the upper part of the rotating cage space. The saw wheel tightens the band saw blade 5. The saw teeth of the band saw blade 5 are opposite to the rotation direction of the rotating cage 3. The band saw blade 5 circulates along the length direction of the rotating cage 3. A plurality of rigid suspension wires 4 arranged along the length direction of the rotating cage 3 are arranged in the rotating cage 3. The band saw blade 5 is parallel to the rigid suspension wire 4. The radial distance from the rigid suspension wire 4 to the center of the rotating cage 3 is greater than the radial distance from the band saw blade 5 to the center of the rotating cage 3. Here, the rigid suspension wire 4 is preferably a steel wire rope, and can also be made of other rigid materials with less elasticity.

[0023] Specifically, a sliding track is provided on the outer periphery of the side wall of the rotating cage 3, a rotating wheel is provided on the bracket 2 to contact the sliding track, the motor 1 drives the rotating wheel to rotate, and the rotating wheel drives the rotating cage 3 to rotate around its center through the sliding track. The two ends of the long cylindrical rotating cage 3 are respectively a feed port and a discharge port. The rotating cage 3 is inclined at an angle to the ground along its rotation axis, that is, the feed port is slightly higher than the discharge port, so that the material can move forward along the inclined angle.

[0024] In this embodiment, there are two cutting band saw devices, and in the two cutting band saw devices, the two band saw blades are arranged in parallel, so as to facilitate cutting the curved peppers in sequence. In this case, the cage wall of the rotating cage 3 has through holes, that is, the top and bottom of the long cylindrical rotating cage 3 are hollow, and its side wall is in the form of a screen with through holes.

[0025] Furthermore, the difference between the radial distance between the suspension line 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, which is convenient for cutting the curved handle. The direction in which the teeth of the band saw blade 5 rotate toward the rotating cage 3 is forward, and a positioning bar 8 is provided in front of the teeth of the band saw blade 5, and at least one side of the positioning bar 8 has a plurality of V-shaped guide grooves. The V-shaped guide groove is used to position the curved handle to be cut to the bottom of the V-shape, so as to facilitate rapid cutting of the curved handle.

[0026] Example 2

[0027] See also Figure 3 The rotating cage 3 can also be composed of a strip profile, and baffles 7 are provided on both sides of the lower part of the rotating cage 3 and the front and rear ends. The space formed by the baffles 7 on the left and right sides of the lower part of the rotating cage 3 and the front and rear ends is used to accommodate the crops to be processed.

[0028] 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.

[0029] 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 prior arts, the utility model will not elaborate on them.

[0030] The working principle of the crop stalk remover provided by the utility model is:

[0031] The bent handle crops to be processed are placed in the rotating cage 3. As the rotating cage 3 rotates, the bent handle crops are hooked by the hanging wire 4 and rotate with the rotating cage 3. When the crops reach the top of the rotating cage 3, they are close to the positioning bar 8, and the bent handle part of the crops is stuck in the V-shaped guide groove of the positioning bar 8. At the same time, the crops are cut by the band saw blade 5. The cut crops are returned to the rotating cage 3 formed by the screen mesh, or the accommodation space of the baffle 7, and are gravity-fed toward the discharge port along the tilt angle of the rotating cage 3. After the cutting is completed, the residual part remaining on the hanging wire 4 is brought back to the lower part of the rotating cage 3 as the rotating cage 3 rotates, leaks out through the screen holes of the baffle 9, and is sent out through the waste conveyor belt 6.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as within the protection scope of the present invention.
