Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural excavating harvesters, specifically relating to an adjustable harvesting and separating device for Chinese medicinal herbs. Background Technology

[0002] Root and tuber crops, such as potatoes, Corydalis rhizome, and Fritillaria bulbs, have high nutritional and medicinal value and are widely cultivated throughout my country. Since the valuable parts of these crops are located in the soil, they are mostly harvested manually, which results in low harvesting efficiency and high labor costs.

[0003] Among existing harvesting excavators for this type of crop, such as the one disclosed in CN106879295B (a harvesting excavator for tuberous and rhizomatous crops), it consists of a frame, a reducer, a mounting frame, a front digging shovel, and a rear digging shovel. The reducer is fixedly mounted at the front of the frame, and crankshafts A and B are symmetrically mounted on the frame behind the reducer via the mounting frame. A power transmission device for the reducer's output is mounted on the frame between crankshafts A and B and the reducer. One end of the power transmission device is connected to the reducer, and the other end is connected to crankshafts A and B. While this can effectively improve harvesting efficiency and reduce labor intensity, it cannot separate the harvested crop from the soil, and the simple structure of the digging shovels may significantly affect digging efficiency when dealing with the diverse soil types found in various parts of my country. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide an adjustable harvesting and separating device for Chinese medicinal herbs, which can separate harvested crops from soil. The separating mechanism can be adjusted to accommodate various sizes and types of crops, and the structure of the digging shovel can be modified to suit different soil types, thereby improving digging efficiency.

[0005] The technical problem solved by this utility model can be achieved by the following technical solution: an adjustable Chinese medicinal herb harvesting, digging, and separating device, including a digging mechanism, a separating mechanism, and a frame. The digging mechanism includes a digging shovel, and the separating mechanism includes a conveyor chain. The conveyor chain includes a plurality of first conveyor shafts, a plurality of second conveyor shafts, and a connecting part. The first and second conveyor shafts include a plurality of separating parts, shaft bodies, and mounting parts. The separating parts are arranged on both sides of the first conveyor shaft and on both sides and the upper part of the second conveyor shaft. Adjacent separating parts on the same shaft body form a splicing part. A plurality of mounting seats are provided on the connecting part. The mounting parts and mounting seats are matched with each other. The first and second conveyor shafts are arranged in an alternating manner so that the separating parts on a single shaft body are located in the splicing parts of adjacent shaft bodies.

[0006] The separator is covered with an adhesive layer.

[0007] The separation mechanism also includes a drive unit located at both ends of the conveyor chain to drive the conveyor chain to move.

[0008] It also includes a rolling section, which includes several second conveyor shafts. The rolling section is positioned above the conveyor chain and rotates.

[0009] It also includes a vibrating part, which is located inside the conveyor chain and rotates. Several vibrating elements are arranged in the circumferential direction of the vibrating part. The rotation of the vibrating part causes the vibrating elements to impact the conveyor chain, causing the first conveyor shaft and the second conveyor shaft to vibrate.

[0010] The excavating shovel has a cutting edge that slopes downwards.

[0011] The cutting edge is straight.

[0012] A protrusion is formed in the middle of the cutting edge.

[0013] The cutting edge is serrated.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0028] Combined with appendix Figures 1 to 9As shown, this embodiment discloses an adjustable medicinal herb harvesting, digging, and separating device, including a digging mechanism 1, a separating mechanism 2, and a frame 3. The digging mechanism 1 is used to dig up crops and soil and feed them into the separating mechanism 2. The frame 3 is arranged on both sides of the digging mechanism 1 and the separating mechanism 2. The digging mechanism 1 includes a digging shovel 11, and the separating mechanism 2 includes a conveyor chain 21. The conveyor chain 21 includes several first conveyor shafts 201, several second conveyor shafts 202, and a connecting part 211. The first conveyor shafts 201 and second conveyor shafts 202 are installed on both sides of the connecting part 211. The first conveyor shafts 201 and second conveyor shafts 202 include several separating parts 2011, shaft bodies 2012, and mounting parts 2013. Preferably, in this embodiment, the first conveyor shafts 201 are provided with two... The second conveyor shaft 202 is provided with three separation components 2011. The separation components 2011 are located on both sides of the first conveyor shaft 201 and on both sides and the top of the second conveyor shaft 202. Adjacent separation components 2011 on the same shaft 2012 form a splicing part 2014. The connecting part 211 is provided with several mounting seats 212. The mounting part 2013 and the mounting seats 212 are matched and fixedly connected by bolts or other fasteners. The first conveyor shaft 201 and the second conveyor shaft 202 are arranged in an interlaced manner, so that the separation components 2011 on a single shaft 2012 are located in the splicing part 2014 of adjacent shafts 2012, that is, the first conveyor shaft 201 and the second conveyor shaft 202 form an interlocking arrangement.

[0029] In combination with the above, preferably, in this embodiment, the distance between the mounting portion 2013 on a single shaft 2012 and the mounting portion 2013 of an adjacent shaft 2012 is 35 to 55 millimeters.

[0030] Combined with the above installation structure, the distance between the first conveyor shaft 201 and the second conveyor shaft 202 can be adjusted, thus making it suitable for separating crops and soil of different sizes. It can also preliminarily separate some crops that have not reached the harvest standard and have small fruits, thereby improving the separation efficiency. Soil falls off from the splicing part 2014, and the crops move to the next process through the conveyor chain 21. The separating part 2011 is covered with an adhesive layer to prevent damage to the crops, resulting in a high crop integrity rate.

[0031] In conjunction with the above installation structure, one of the separating components 2011 of the second conveying shaft 202 is located on the upper side of the shaft body 2012, which can initially break up the soil and improve the separation efficiency of crops and soil.

[0032] In conjunction with the above, the separation mechanism 2 also includes a drive unit 22, which is located at both ends of the conveyor chain 21 and is externally connected to a drive device such as a motor, so that the drive unit 22 can rotate. Preferably, a plurality of drive blocks are provided on the inner side of the conveyor chain 21 and drive teeth are provided on the outer side of the drive unit 22. When the drive unit 22 rotates, the drive teeth push the drive blocks, thereby driving the conveyor chain 21 to move.

[0033] In conjunction with the above, the system also includes a rolling section 23, which comprises a plurality of second conveying shafts 202 interconnected to form a circumference. The rolling section 23 is positioned above the conveyor chain 21 and is externally connected to a driving device such as a motor, causing the rolling section 23 to drive the second conveying shafts 202 to rotate. Preferably, in this embodiment, there is a certain distance between the second conveying shafts 202 of the rolling section 23 and the first conveying shafts 201 and second conveying shafts 202 of the conveyor chain 21. The rolling section 23 can initially break up and separate the soil transported to this location, dispersing the soil into small pieces, thereby improving the efficiency of subsequent separation.

[0034] In conjunction with the above, it also includes a vibration section 24, which is disposed inside the conveyor chain 21 and externally connected to a driving device such as a motor, so that the vibration section 24 can rotate. The vibration section 24 is provided with a plurality of vibrating elements 241 in the circumferential direction. Preferably, in this embodiment, the number of vibrating elements 241 is 3. The rotation of the vibration section 24 causes the vibrating elements 241 to impact the conveyor chain 21, causing the first conveyor shaft 201 and the second conveyor shaft 202 to vibrate, thereby improving the separation effect.

[0035] In combination with the above, the two ends of the digging shovel 11 are hinged to the two sides of the frame 3. The digging shovel 11 is provided with a cutting edge 111, and the cutting edge of the cutting edge 111 is inclined downward, which can improve the digging effect of the digging shovel 11.

[0036] Based on the above installation structure and the soil conditions of the application environment of this utility model, any one of the digging shovels with different cutting edges 111 can be selected from the following embodiments. Example

[0037] Based on Example 1, combined with Figure 6 As shown, the cutting edge 111 is straight, which is suitable for most common soil types. Example

[0038] Based on Example 1, combined with Figure 7 As shown, the middle of the cutting edge 111 protrudes outward, which can effectively break up some harder soil clods. Example

[0039] Based on Example 1, combined with Figure 8 As shown, the cutting edge 111 is serrated, which is suitable for soils with a relatively hard overall texture. Example

[0040] Based on Example 1, combined with Figure 9 As shown, the middle of the cutting edge 111 is concave, which is suitable for soils with relatively loose texture or crops that are easily damaged.

[0041] The above structure enables this utility model to be applied to most application environments, thus improving its applicability and practicality.

[0042] This invention can separate harvested crops from soil, and the separation mechanism can be adjusted to suit various crops of different sizes and types. It can also modify the structure of the digging shovel to suit different soil types, thereby improving digging efficiency.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
