Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to a cyperus chinensis separation device. Background Art

[0002] The growing environment of cyperus esculentus is similar to that of peanuts, and its shape and size are similar to those of peanuts without their shells. Since cyperus esculentus grows underground, the rhizomes of the plant's stems and leaves are connected to the cyperus esculentus, and a large number of rhizomes penetrate deep into the soil. When harvesting, the bean-soil mixture must be dug, transported, screened, and collected. Due to the large amount of sand and soil during harvesting, all cyperus esculentus harvesters are unable to increase the harvest yield.

[0003] Initially, harvesting cyperus chinensis relied on manual labor to remove the plant stems and leaves from the ground. The leaves were then shaken to separate the berries from the rhizomes. In recent years, some cyperus chinensis harvesters have been developed, but they cannot completely separate the berries from the stems and leaves. Consequently, a significant amount of berries remain on the stems and leaves, requiring manual sorting, significantly increasing harvesting costs and time. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problem of incomplete separation of cyperus chinensis in the prior art and to provide a cyperus chinensis separation device, which has good separation performance of plant stems and leaves from cyperus chinensis.

[0005] In order to achieve the above-mentioned objectives, the present invention provides a device for separating jatropha, comprising a bearing layer, an upper separation structure and a lower separation structure; the bearing layer is used to carry the soil and jatropha carried by the plant rhizomes, and a gap is provided on the bearing layer; the upper separation structure is located above the bearing layer and is used to move the stems and leaves of the plant on the bearing layer; the lower separation structure is located in the middle of the bearing layer, and is used to hit the plant rhizomes to separate the jatropha and sand; wherein, the lower separation structure comprises a lower rotating shaft and a steel wire braid, a first threaded hole is provided on the lower rotating shaft, the steel wire braid is fixed to the lower rotating shaft through the first threaded hole, the lower rotating shaft drives the steel wire braid to rotate, and when the steel wire braid rotates, it passes through the gap to hit and move the plant rhizomes, and brings the plant stems and leaves through the gap to the bottom of the bearing layer.

[0006] Preferably, the radial cross-section of the lower rotating shaft is hexagonal; a row of the first threaded holes is provided on each of the six sides of the lower rotating shaft; and the distance between adjacent first threaded holes on one side is 8 to 15 mm.

[0007] Preferably, the length of the braided steel wire is 140-160 mm.

[0008] Preferably, the upper separation structure includes an upper rotating shaft and a dial plate, the upper rotating shaft is provided with a second threaded hole, and the dial plate is fixed to the upper rotating shaft by being threadedly connected to the second threaded hole.

[0009] Preferably, the radial cross-section of the upper rotating shaft is hexagonal, and each of the six sides of the upper rotating shaft is provided with a row of the second threaded holes.

[0010] Preferably, the second threaded holes on adjacent surfaces are staggered.

[0011] Preferably, the distance between adjacent threaded holes on one side is 35-45 mm.

[0012] Preferably, the shifting plate includes two fixing plates, the two fixing plates are rectangular, and the two fixing plates are connected and fixed at the long sides.

[0013] Preferably, the length of the two fixing plates is 145-155 mm, and the angle between the two fixing plates is 150°-170°.

[0015] Through the above technical solution, the separation device of the present invention separates the plant stems and leaves from the cyperus rotundus. In the separation device, the bearing layer is used to carry the plant stems and leaves, the cyperus rotundus carried by the plant rhizomes, and the soil, and assists the upper separation structure and the lower separation structure to separate the cyperus rotundus. At the same time, an upper separation structure is provided above the bearing layer, and the upper separation structure is used to move the cyperus rotundus. The lower separation structure in the middle of the bearing layer knocks the plant rhizomes and moves the plant stems and leaves, and separates the plant stems and leaves to the bottom of the bearing layer through the gap, and separates the cyperus rotundus and sand from the plant rhizomes.

[0030] like Figure 1-9 As shown, the present invention discloses a cyperus chinensis separation device 100, which includes a bearing layer 1, an upper separation structure 2 and a lower separation structure 3; the bearing layer 1 is used to carry the soil and cyperus chinensis carried by the plant rhizomes, and a gap 13 is provided on the bearing layer 1; the upper separation structure 2 is located above the bearing layer 1, and is used to move the plant stems and leaves on the bearing layer 1; the lower separation structure 3 is located in the middle of the bearing layer 1, and is used to hit the plant rhizomes to separate the cyperus chinensis and sand; wherein the lower separation structure 3 includes a lower rotating shaft 31 and a steel wire braid 32, and the lower rotating shaft 31 is provided with a first threaded hole 311, and the steel wire braid 32 is fixed to the lower rotating shaft 31 through the first threaded hole 311, and the lower rotating shaft 31 drives the steel wire braid 32 to rotate. When the steel wire braid 32 rotates, it passes through the gap 13 to hit and move the plant rhizomes, and brings the plant stems and leaves through the gap 13 to the bottom of the bearing layer 1.

[0031] The separation device of the present invention separates the plant stems and leaves from the cyperus rotundus. In the separation device, the supporting layer 1 is used to carry the plant stems and leaves, the cyperus rotundus carried by the plant rhizomes, and the soil to assist the upper separation structure 2 and the lower separation structure 3 in separating the cyperus rotundus. At the same time, the upper separation structure 2 arranged above the supporting layer 1 is used to move the plant stems and leaves, and the lower separation structure 3 arranged below the supporting layer 1 is used to knock and move the plant rhizomes, and separate the plant stems and leaves to the bottom of the supporting layer 1 through the gap 13, and separate the cyperus rotundus and sand from the plant rhizomes. The cyperus rotundus remains on the supporting layer 1. In the lower separation structure 3, a lower rotating shaft 31 and a steel wire braid 32 are provided. The first threaded hole 311 is provided on the lower rotating shaft 31, and the steel wire braid 32 is connected to the lower rotating shaft 31 through the first threaded hole 311. The lower rotating shaft 31 drives the steel wire braid 32 to rotate, so that the steel wire braid 32 drives the stems and leaves of the plant to move to the bottom of the supporting layer 1. The gaps 13 on the supporting layer 1 cannot pass through the cyperus juncea, so that the cyperus juncea and the rhizome of the plant are separated under the tension of the steel wire braid 32; the steel wire braid 32 of the present invention can effectively peel off the stems and leaves of the plant through the gaps 13 on the supporting layer 1 to the bottom of the supporting layer 1, peeling off the cyperus juncea from the rhizome, greatly solving the problem of incomplete separation of cyperus juncea and ensuring the harvest rate of cyperus juncea.

[0032] like Figures 2 to 4As shown, the lower rotating shaft 31 of the present invention has a hexagonal cross-section, meaning it has six flat surfaces, each of which is provided with a row of first threaded holes 311. The distance between adjacent first threaded holes 311 on a single surface is 8 to 15 mm. To ensure that the steel wire braid 32 on the rotating shaft fully strikes and strips the plant rhizomes on the supporting layer 1, the first threaded holes 311 are positioned on all six surfaces of the lower rotating shaft 31. The spacing between the first threaded holes 311 is set between 8 and 15 mm, and can be adjusted based on the actual terrain, the amount of soil covering the plant rhizomes, and the size of the jatropha.

[0033] To better separate the cyperus rotundus from the plant's rhizomes, the length of the steel wire braid 32 is set between 140 and 160 mm, with an optimal length of 150 mm being sufficient for fully separating the cyperus rotundus. The steel wire braid 32 is threadedly fixed to the lower rotating shaft 31, so the length of the steel wire braid 32 can be adjusted at any time according to actual conditions. The steel wire braid 32 can also be replaced if it becomes worn or damaged, ensuring the proper functioning of the separation device.

[0034] The upper separation structure 2 includes an upper rotating shaft 21 and a dial plate 22. A second threaded hole 211 is provided on the upper rotating shaft 21. The dial plate 22 is fixed to the upper rotating shaft 21 by being threadedly connected to the second threaded hole 211. The dial plate 22 can dial the jujube on the bearing layer 1 to move the jujube upward; the radial cross-section of the upper rotating shaft 21 is hexagonal and has the same structure as the lower rotating shaft 31. A row of second threaded holes 211 are provided on all six sides of the upper rotating shaft 21, and the distance between adjacent threaded holes on one side is 35 to 45 mm; due to the large width of the dial plate 22, the distance between the threaded holes needs to be set between 35 mm and 45 mm to ensure that the distance between the dial plates 22 can be normally installed. At the same time, the dial plate 22 installed through the second threaded hole 211 can be replaced when the dial plate 22 is damaged. When the length of the dial plate needs to be adjusted, it can be replaced for easy operation.

[0035] In order to prevent the cyperus juncea from being missed in the gaps between the plucking plates 22, the second threaded holes 211 on adjacent surfaces are staggered so that the gaps 13 between adjacent plucking plates 22 on one surface correspond to the plucking plates 22 on adjacent surfaces, ensuring that the cyperus juncea is not missed.

[0036] Specifically, the paddle 22 includes two rectangular fixed plates 221, connected and fixed along their long sides. The lengths of the two fixed plates 221 are 145 to 155 mm, the widths are 35 to 40 mm, and the included angle between the two fixed plates 221 is 150° to 170°. To maximize the efficiency of the paddle 22 in moving the cyperus juncea, the included angle between the two fixed plates 221 is set between 150° and 170°, with the included angle oriented in the direction of the cyperus juncea movement to ensure proper movement.

[0037] Furthermore, the bearing layer 1 includes a steel wire 11, two fixed shafts 12 and two expansion wheels 14. The two fixed shafts 12 are located at both ends of the bearing layer 1. The steel wire 11 is wrapped around the axial direction of the two fixed shafts 12. The two expansion wheels 14 are respectively located under the two fixed shafts 12 and are used to adjust the tension of the steel wire 11. A lower layer separation structure 3 is provided between the upper and lower steel wires 11. Adjacent steel wires 11 form the gap 13, and the width of the gap 13 is 7 to 9 mm. In order to separate the cyperus juncea from the rhizomes and prevent it from falling under the supporting layer 1, the steel wire 11 is wrapped around two fixed shafts 12 in an S shape on the supporting layer without overlapping. The distance of the gap 13 between the steel wires 11 is between 7 and 9 mm, ensuring that the steel wire braid 32 and the stems and leaves of the plant can pass through without missing the cyperus juncea; the expansion wheel 14 can adjust the tightness of the steel wire 11 to ensure the normal operation of the steel wire 11 and the fixed distance between the steel wires 11; the fixed shaft 12 of the present invention is rotatable, and has the same rotation direction as the lower separation structure 3, so as to be used to transport the cyperus juncea and drive the steel wire 11 to rotate. During the rotation process, the steel wire 11 can promote the steel wire braid 32 to drag the stems and leaves of the plant to the bottom of the supporting layer, thereby increasing the stripping efficiency of the cyperus juncea.

[0038] In order to improve the peeling effect of cyperus juncea, the present invention sets the distance between the steel wire 11 and the lower layer shaft 31 to be between 15 mm and 30 mm, ensuring that the stems and leaves of the plant are pressed under the supporting layer 1 to the maximum extent to peel the cyperus juncea.

[0039] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be regarded as disclosed in the present invention and fall within the scope of protection of the present invention.
