and the collection strip collection system is used for outputting the harvested dwarf lilyturf roots.
Aiming at the problem that an agricultural machine specially suitable for harvesting radix ophiopogonis is lacked in the prior art, the invention provides a circulating sieve type radix ophiopogonis harvester. During the operation, the harvester is driven by existing field operation equipment such as a tractor to move forward, the radix ophiopogonis to be harvested is dug out together with soil through the digging system during the moving forward, the dug radix ophiopogonis and the soil are used as materials to enter the conveying system and are conveyed to the primary rolling soil crushing system through the conveying system, the rolling soil crushing system rolls and crushes the soil during the conveying process, and large blocks of soil are rolled and cracked. For the harvest of the radix ophiopogonis, the inventor finds that the soil blocks adhered to the roots and the stems are difficult to effectively remove only by means of a soil rolling and smashing technology in a large number of experimental research processes, and the reason is that soil for planting the radix ophiopogonis generally has the characteristic of strong soil viscosity, so that a large amount of soil and stem mixture processed by the soil rolling and smashing system enters a primary soil rolling and smashing system, the cohesive soil blocks attached to the roots and the stems of the radix ophiopogonis are subjected to primary extrusion and smashing, then the materials fall to a circulating screening system, the materials are conveyed to a secondary soil rolling and smashing system by the circulating screening system, the soil blocks attached to the roots and the stems of the radix ophiopogonis are subjected to secondary extrusion and smashing, and small pieces of soil adhered to the roots and the residues are further extruded and smashed. The soil blocks adhered to the radix ophiopogonis processed by the secondary rolling soil crushing system are basically processed completely, fall onto the circulating screening system again, are conveyed to the strip collecting system by the circulating screening system, and are output by the strip collecting system. The utility model provides an it is as an organic whole that this application collects degree of depth excavation, hack and carries, circulation screening, collection function, has effectively solved the difficult problem of screening of tuber of dwarf lilyturf rhizome under the cohesive soil condition. The application of this application can make tuber of dwarf lilyturf traditional chinese medicinal material realize replacing traditional artifical results with efficient mechanical harvesting mode to make the tuber of dwarf lilyturf can realize effects such as high efficiency, low cost, low fruit rate, low breakage rate of falling in the harvest process.
In the application, the front and the back are both forward in the advancing direction of the dwarf lilyturf tuber harvester and backward in the reverse direction.
Further, the excavation system comprises a second-order curved surface excavation shovel, the second-order curved surface excavation shovel comprises a shovel body inclining forwards and inclining downwards, a triangular pyramid with the vertex facing forwards is arranged in the middle of the shovel body, and the triangular pyramid divides the shovel body into a first plane part and a second plane part which are distributed left and right; the first plane part and the second plane part are gradually inclined downwards from one end close to the triangular pyramid to one end far away from the triangular pyramid.
The inventor finds that the digging shovel of the existing rhizome crop harvester is a common plane shovel, the digging effect is poor when the radix ophiopogonis is harvested, and the digging efficiency is not high in the further research process. The reason for this is that radix ophiopogonis has special requirements on planting soil conditions, is suitable for slightly alkaline sandy loam with loose soil, rich and moist soil and good drainage, and the occurrence and growth of fibrous roots and poor growth of root tubers are influenced by over-heavy planting soil; if the sand property is too heavy, the soil water and fertility preservation is weak, the plant growth is poor, and the yield is low; therefore, farmers generally use cohesive soil with moderate sand property for planting the dwarf lilyturf tuber, and the common plane shovel has a general crushing effect on the soil, so that the digging efficiency is not high. Therefore, the second-order curved surface digging shovel specially used for automatically harvesting radix ophiopogonis is designed in the scheme, and the shovel body of the shovel still inclines forwards and downwards so as to be convenient to be eaten into a soil layer; this scheme sets up the triangular pyramid at shovel body middle part to make the summit of triangular pyramid forward, directly split soil through summit forward. The shovel bodies on two sides of the triangular pyramid are respectively defined as a first plane part and a second plane part and are respectively inclined towards two sides, so that for the first plane part and the second plane part in the scheme, the surfaces of the first plane part and the second plane part are simultaneously inclined forwards and outwards, and the shovel bodies can be gradually and stably deep into a soil layer along with the advancing of the dwarf lilyturf tuber harvester. According to the scheme, the soil is divided into two parts by breaking the soil through the triangular pyramid, and then the upper soil is shoveled by gradually penetrating the plane parts at two sides into the soil layer, so that the purpose of shoveling the radix ophiopogonis with the soil is achieved, compared with the traditional plane shovel, the soil-entering effect is obviously improved, and the digging efficiency is favorably improved; meanwhile, due to the fact that the triangular pyramid is separated and the two plane portions are respectively arranged in an outward inclining mode, under the condition that the shovel surface inclination angle and the total length are the same, the shovel surface pressure is lower than that of a conventional plane shovel, and through modeling analysis, when the digging shovel inclination angle is 15 degrees, the shovel surface pressure is lower than that of the common plane shovel by 49.3 percent; the inclination angle herein corresponds to the application, and means an inclination angle at which the first plane part and the second plane part are inclined downward from back to front.
