Secondly, the high purchase cost hinders the widespread use of agricultural machinery.
Thirdly, the current yam planting farmers are individual farmers of the farmers generally, and the maintenance knowledge and the practical ability of the agricultural machinery are to be improved. In the harvesting season, if the agricultural machine is damaged and cannot be maintained in time, the harvesting time of the Chinese yam can be greatly delayed, and the income of farmers and the planting of crops in the next season are influenced.
Fourthly, the key point is that all the Chinese yam harvesting devices need to dig ditches at present, the power output of agricultural machinery is large, more diesel oil is consumed, the soil disturbance is large, Chinese yams cannot be continuously planted in the same farmland and need to be subjected to intermediate fallow for two to three years, and the planting of crops in the next season is influenced when the soil disturbance is large.
In addition, the existing yam harvesting device does not fully utilize the characteristics of yam planting soil and harvesting season. It is well known that in order to obtain good yam quality, the soil in which yams are best grown is loose sandy soil. Sandy soil is characterized by high sand content, coarse grains, high water seepage speed, poor water retention performance and good ventilation performance. The harvesting season of the Chinese yam is autumn, in the northern China, namely the main production area of the Chinese yam, the autumn is dry and has little rain, and the soil has low moisture content and becomes loose and fragile.
If the soil characteristics of yam planting and the climatic characteristics of the harvesting season can be combined, an energy-saving and convenient yam harvesting machine can be formed.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In order to fully utilize the sandy soil characteristic of the planted Chinese yam, the invention firstly provides a rhizome crop harvesting method, which comprises the following steps:
referring to fig. 1 and 2, soil 100 on both sides and bottom of a rhizome 200 of yam is first cut to form a cut around the rhizome 200, so that soil (e.g., soil 1000 in fig. 4 and 5) surrounding the rhizome 200 is separated from soil at a greater distance.
The soil surrounding the crop roots (e.g., soil 1000) is then lifted, preferably gradually, rather than abruptly vertically.
The lifted soil (e.g., soil 1000) is then quickly dropped and the sandy soil disintegrates. The soil (e.g., soil 1000) surrounding the crop rootstock 200 is loosened, and the crop rootstock 200 is pulled along the upper end of the crop rootstock 200 or the plant 201 of the crop rootstock.
More preferably, in order to implement the above method, the present invention further provides a rhizome crop harvesting apparatus, as shown in fig. 3, 4, and 5, comprising: frame 1, first cutting board 2, second cutting board 3, third cutting board 4, lift plate 5.
Particularly, frame 1 is frame rack construction, provides the integral support effect, and the front end is equipped with coupling mechanism 11 and is used for being connected with the suspension mechanism of tractor, because the agricultural equipment that can be connected with tractor suspension mechanism at present is more: ploughs, seeders, etc., and moreover the frame 1 and its connection mechanism 11 of the present invention are capable of supporting, connecting, so that the structure thereof will not be described in detail, and the operation process thereof is similar to that of a plough.
The first cutting plate 2 is vertically arranged, the upper part of the first cutting plate is fixed on the rack 1, and the front side edge of the first cutting plate is provided with a cutting edge 21 for cutting soil. The second cutting board 3 is vertically arranged, is arranged in parallel with the first cutting board 2 in the same height, the upper part is fixed on the frame 1, and the front side edge is provided with a cutting edge 31 for cutting soil. Third cutting board 4 level sets up, and both ends are connected respectively in the lower side of first cutting board 2, second cutting board 3 about, and preceding side sets up blade 41 in order to cut soil. The whole body formed by the first cutting plate 2, the second cutting plate 3 and the third cutting plate 4 is of a U-shaped structure with flat bottom, and the upper end of the U-shaped structure is connected with the frame 1. The distance between the first cutting plate 2 and the second cutting plate 3 is similar to the width of a ridge of Chinese yams, and cannot be too wide, because too much power and oil of a tractor are consumed when too much soil 100 is cut; nor too narrow, since cutting too little soil 100 will likely cut the rootstock 200.
The lifting plate 5 is located between the first cutting plate 2 and the second cutting plate 3, the front side edge is connected to the rear side edge of the third cutting plate 4, and the rear side edge of the lifting plate 5 extends obliquely upward to gradually lift the soil cut by the first cutting plate 2, the second cutting plate 3 and the third cutting plate 4, as shown in fig. 4 and 5.
In order to increase the structural strength, the left and right side edges of the lifting plate 5 of the first embodiment of the apparatus of the present invention are partially or entirely connected to the inner walls of the first cutting plate 2 and the second cutting plate 3, as shown in fig. 4, and the front end portion of the lifting plate 5 is connected to the inner walls of the first cutting plate 2 and the second cutting plate 3 (not shown), and obviously, the structure requires the first cutting plate 2 and the second cutting plate 3 to be wide.
In order to obtain a sufficient height of the cut and lifted soil, a large speed is obtained during rapid landing, and the Chinese yam is not broken, the height of the lifting plate 5 is more than or equal to half of the height of the first cutting plate 2 after repeated tests.
In order to make the soil to be cut and lifted hang for a longer time and receive the vibration caused by bumping from the tractor and the device for a longer time, the soil is looser, the rear side edge of the lifting plate 5 is connected with a horizontally arranged support plate 6, and the width of the support plate 6 is less than or equal to that of the lifting plate 5. The arrangement of the support plate 6 makes it possible to expose the soil 1000 lifted out of the ground for a longer time in the air, that is, the soil 1001 around the upper end of the root stalk 200 is more easily scattered to the ground, so that the root stalk 200 is more easily pulled out.
As shown in fig. 4 and 5, in the first embodiment, when the machine frame 1 drives the first cutting plate 2, the second cutting plate 3, and the third cutting plate 4 to advance, the cutting edges of the first cutting plate 2, the second cutting plate 3, and the third cutting plate 4 cut the soil 100, and form the cutting surface 20, the cutting surface 30, and the cutting surface 40, respectively, so as to separate the soil 1000 tightly surrounding the rhizome 200 from the surrounding soil 100. Immediately after the lifting plate 5, the cut soil 1000 with the rootstocks 200 wrapped therein is gradually lifted to be obviously higher than the ground 101, the soil 1000 is held in the air for a period of time due to the support of the supporting plate 6, and a part 1001 of the soil 1000 is scattered to the ground 101 to two sides due to the vibration and the sand property. At the end of the support plate 6, the soil 1000 suddenly loses support and falls quickly into the suspended area 1002 below the support plate 6, the soil 1000 "falls" more loosely, and the top of the rootstock 200 or the plant 201 thereof is pulled manually, so that the rootstock 200 can be easily pulled out of the ground 101.
In another embodiment, as shown in fig. 6, compared with the first embodiment, the supporting plate 6 is not provided, but the soil diffusion plate 60 is provided, the soil diffusion plate 60 is in an upwardly arched shape, the front side of the soil diffusion plate 60 is connected to the rear side of the lifting plate 5, and the width of the soil diffusion plate 60 is smaller than or equal to the width of the lifting plate 5. As can be seen from fig. 6, in the case that the front and rear lengths are the same, the upper surface area of the soil spreading plate 60 is significantly larger than that of the support plate 6, that is, the same soil 1000 will be distributed on the larger soil spreading plate 60, so that the soil spreading plate 60 can form larger cracks 1003 (or the soil 1000 is more easily broken, and the cracks 1003 are only used for expressing the meaning of "fragile"), and in view of this, the roots 200 are more easily pulled out of the soil 1000, so that a standing position and a root placing rack can be arranged above the frame 1, the roots 200 can be immediately harvested, the length of the frame 1 is increased, and support wheels (not shown) can be arranged below the rear portion of the frame 1 to play a role of stabilizing the frame 1.
In the first and second embodiments, only one ridge of Chinese yam can be harvested at a time, and in order to harvest two ridges of Chinese yam simultaneously, the third embodiment is provided in the present invention, as shown in fig. 7 and 8, compared with the first embodiment, a fourth cutting board 403 is additionally provided, the fourth cutting board 403 is vertically arranged, is arranged in parallel with the first cutting board 402 and the second cutting board 404 in equal height, and the upper portion of the fourth cutting board 403 is fixed to the frame 1. The front side edges of the first cutting plate 402, the second cutting plate 404, the fourth cutting plate 403 and the third cutting plate 400 are respectively provided with an edge 4021, an edge 4041, an edge 4031 and an edge 401 to cut the soil 100.
The fourth cutting plate 403 and the first cutting plate 402 are respectively located on two sides of the second cutting plate 404, and the distance between the fourth cutting plate 403 and the second cutting plate 404 and the distance between the first cutting plate 402 and the second cutting plate 404 are both greater than or equal to the width of one ridge of the root-tuber 200 crop. The upper surface of the third cutting board 400 is simultaneously connected to the lower sides of the first cutting board 402, the second cutting board 404, and the fourth cutting board 403. Of course, a lifting plate is also provided between the second cutting plate 404 and the fourth cutting plate 403.
More preferably, as shown in fig. 7, in the advancing direction, the second cutting plate 404 is arranged forward, the first cutting plate 402 and the fourth cutting plate 403 are arranged backward, the front portion of the third cutting plate 400 is V-shaped, and the projection of the front side edge of the second cutting plate 404 on the third cutting plate 400 coincides with the tip of the third cutting plate 400. In this manner, soil 100 may be cut more efficiently.
When yams are harvested according to the third embodiment, since the first cutting plate 402, the second cutting plate 404, and the fourth cutting plate 403 can simultaneously cut the soil, the cutting surfaces (cuts) 2011 left on the soil 100 in a top view are as shown in fig. 8, and two ridges of yams are harvested simultaneously.
In conclusion, the invention can lift the soil wrapping the root crops such as Chinese yam and the like out of the ground surface without a ditching mechanism and a vibration mechanism, then drop the soil suddenly, and utilize the characteristic of sandy soil to cause the soil to generate huge disturbance and fragmentation, thereby being capable of pulling out the Chinese yam relatively easily. The structure is particularly simple, the manufacturing cost is particularly low, the use cost is particularly low, and the maintenance is also particularly simple (only welding, edging and the like are needed).
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
