Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a crop stem removing machine. Background Art

[0002] As demand for export trade grows, my country's exports of chili peppers to various parts of the world are also increasing. The processing of finished chili peppers has gradually shifted from traditional manual sorting by workers to industrial machinery batch operations. For the process of removing the stems of chili peppers, there are several mechanical processing methods on the market. For example, the chili peppers are placed in a drum with mesh holes. The drum rotates, causing the chili stems to fall into the mesh holes, and a cutter set on the outside of the drum cuts off the chili stems. This stem-cutting method has a narrow scope of application and cannot automatically remove the stems of chili peppers with curved stems. Therefore, it is necessary to design a stem-cutting device that can automatically remove chili stems of any shape and has a wider range of applications. Utility Model Content

[0022] The following embodiments of the present invention are described in further detail with reference to 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.

[0023] See Figures 1 to 3The crop stem removing machine provided by the present invention includes a bracket 1 and a motor (not shown in the figure). A supporting conveyor belt 2 and a kneading belt 3 are installed on the bracket 1. The motor 1 drives the supporting conveyor belt 2 and the kneading belt 3 to rotate. The kneading belt 3 is arranged obliquely above the supporting conveyor belt 2. The angle between the surface of the kneading belt 3 and the surface of the supporting conveyor belt 2 is acute. The end of the kneading belt 3 close to the supporting conveyor belt 2 does not contact the supporting conveyor belt 2, leaving a gap 203. Here, the kneading belt 3 is used to rub and rub the crops on the supporting conveyor belt 2 to facilitate the removal of crop stems. The height range of the gap 203 between the kneading belt 3 and the supporting conveyor belt 2 is 1 to 8 cm, preferably 2 to 3 cm. It can be set according to actual needs and is not limited by the present invention.

[0024] Furthermore, the cyclic rotation direction of the kneading belt 3 is the same as that of the supporting conveyor belt 2. That is, relative to any side of the crop stem remover, the kneading belt 3 and the supporting conveyor belt 2 both rotate clockwise or counterclockwise. When the machine is running, the side of the kneading belt 3 opposite the supporting conveyor belt 2 pulls back the crops being transported forward on the supporting conveyor belt 2 to increase friction on the crops and achieve the effect of removing the stems. The surfaces of the kneading belt 3 and the supporting conveyor belt 2 are provided with multiple raised ribs 4 along the width direction. During the transportation of the crops, the ribs 4 rub the crops up and down, further facilitating the removal of dry crop stems.

[0025] The crop stem-removing machine provided in this embodiment also features a feed thumbwheel, located at the acute-angled opening of the kneading belt 3, away from the supporting conveyor belt 2. Two sets of feed thumbwheels are provided: feed thumbwheel 1 5, located above the supporting conveyor belt 2, and feed thumbwheel 2 6, located below the kneading belt 3. Feed thumbwheels 1 5 and 6 are used to control the feed rate of crops onto the supporting conveyor belt 4.

[0026] The acute angle opening of the kneading belt 3 away from the supporting conveyor belt 2 is the feed port, and the gap 203 is the discharge port. The supporting conveyor belt 2 at the feed port is longer than the kneading belt 3. The part where the supporting conveyor belt 2 is longer than the kneading belt 3 is installed with a baffle 8, which is used to hold the crops at the feed port.

[0027] The crop stem remover provided in this embodiment also includes a cleaning roller 7, which is positioned horizontally above the kneading belt 3. The cleaning roller 7 is in close contact with the surface of the kneading belt 3. The cleaning roller 7 is driven by a motor and rotates synchronously with the kneading belt 3 to remove crops adhered to the surface of the kneading belt 3. The surface of the cleaning roller 7 can be a brush or steel wire, which is not limited to this invention.

[0028] In summary, according to the crop stem-removing machine provided by the present invention, the kneading belt is arranged obliquely above the supporting conveyor belt, and the angle between the surface of the kneading belt and the surface of the supporting conveyor belt is acute. The end of the kneading belt close to the supporting conveyor belt does not contact the supporting conveyor belt, leaving a gap. The cyclic rotation direction of the kneading belt is the same as the cyclic rotation direction of the supporting conveyor belt, which can effectively rub off the stems of the crops. The raised ridges provided along the width direction of the kneading belt and the surface of the supporting conveyor belt will cause the pepper stems to fall off due to friction caused by the raised ridges on the upper and lower conveyor belts, thereby completing the automatic stem removal of the crops.

[0029] 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.
