The rod body 14 is provided with a hook 21 at each of two ends of the strip-shaped hole 19, and the steel wire rope 16 is of an annular structure and is sleeved on the two hooks 21. The shaft body 20 is provided with a fixing rod 18 at each rod body 14, the rear end of the fixing rod 18 is fixedly connected with the shaft body 20, and the front end of the fixing rod is positioned at the front upper position. The front end and the rear end of the spring 17 are respectively connected to the front end of the fixing rod 18 and the steel wire rope 16, and the rear end of the spring 17 is provided with a circular ring or a hook body which is sleeved on the annular steel wire rope 16. The rod body 14 can move back and forth along the direction of the strip-shaped hole 19 through the action of the strip-shaped hole 19, and the rod body 14 can be pulled to the lower side direction through the action of the spring 17. When the vertical type telescopic rod normally works, the shaft body 20 is fixed, the rod body 14 rotates around the shaft body 20 along with the cylinder, and when the rod body 14 is in a vertical state, as shown in the left side of fig. 4, the upper end extends upwards, and the lower end is retracted; when the lower end of the peanut seedling picking rod is forwards moved backwards along the shell 15 to a state shown on the right of a figure 4, the lower end of the peanut seedling picking rod extends forwards and downwards under the action of the spring 17 and is inserted below the peanut seedlings to pick up the peanut seedlings to drive the peanut seedlings to rotate backwards along the shell 15, when the peanut seedlings rotate to the back of the shell 15, the rod body 14 retracts into the shell 15, the peanut seedlings freely fall backwards along the shell 15 and fall into the picking platform 2, and therefore the picking work of the peanut seedlings is completed. Inside body of rod 14 of casing 15 below was received into casing 15 to avoid body of rod 14 lower extreme and pick up 2 leading edges of platform and ground to the collision, thereby can make casing 15 be close to ground more, thereby make the pickup cleaner. When the rod body 14 below in front extends out, the peanut seedlings are inserted into the lower part of the peanut seedlings to be picked up, the action simulates the process of manually picking up the peanut seedlings by using a fork, and the mode has the characteristic of picking up the peanut seedlings cleanly.

A scraper conveyor is arranged in the gap bridge body 3, and peanut seedlings are conveyed into the machine body 4 through the scraper conveyor.

The machine body 4 is provided with a front roller tooth 12 and a rear roller tooth 13, and the main shafts of the two roller teeth are along the transverse direction (i.e. the width direction of the vehicle body). Wherein the front hobbing 12 is positioned at the rear of the gap bridge body 3, the rear hobbing 13 is positioned at the rear of the front hobbing 12, and screens 23 are respectively arranged below the two hobbing. The front hobbing 12 includes a main shaft and a plurality of horizontal bars surrounding the circumference of the main shaft. The rear tip 13 includes a main shaft and a plurality of screw rods. The spiral rod surrounds the periphery of the main shaft and is of a spiral structure, so that when the rear roller teeth 13 rotate, the peanut seedlings can be driven to move along the axial direction of the main shaft. The horizontal rod and the spiral rod are provided with a series of teeth, and the peanut seedlings are driven to synchronously rotate along with the roller teeth through the action of the teeth. The screen 23 is provided with a series of screen holes, peanut seedlings are beaten on the screen 23 along with the roller teeth, and in the beating process, peanuts are beaten, separated from the peanut seedlings and fall out of the screen 23. The peanut seedlings are beaten once on the front hobbing 12 and then are sent to the rear hobbing 13, beating is continuously carried out on the rear hobbing 13, and then the hobbing 13 moves backwards while rotating until the peanut seedlings move to the end part of the rear hobbing 13. An opening is arranged at the end part of the machine body 4 positioned at the rear roller teeth 13, the opening is positioned at the seedling storage cage 10, and the inner cavity of the machine body 4 is communicated with the seedling storage cage 10 through the opening, so that peanut seedlings after picking up enter the seedling storage cage 10.

The vibrating screen 8 is located below the screen 23, so that picked peanuts fall on the vibrating screen 8, sandy soil and crushed peanut seedlings also fall on the vibrating screen 8, screen holes are formed in the vibrating screen 8, the sandy soil leaks from the screen holes under the action of the screen holes, the peanuts are left on the vibrating screen 8, and the peanuts are driven to move backwards under the vibrating action of the vibrating screen 8. The fan 7 is positioned above the rear half section of the vibrating screen 8, and light impurities such as crushed peanut seedlings, leaves and mulching films on the vibrating screen 8 are sucked under the action of the fan 7. An air outlet of the fan 7 is positioned on the seedling storage cage 10, and impurities such as crushed peanut seedlings and the like are fed into the seedling storage cage 10 under the action of the fan 7.

The fruit storage box 5 is positioned above the rear half section of the vibrating screen 8, and the fruit storage box 5 is of a box body structure with an opening at the upper part. Lifting machine 6 is equipped with between 8 rear ends of shale shaker and the storage fruit case 5 upper portion opening part, and the peanut on the shale shaker 8 falls from 8 rear ends of shale shaker, falls in lifting machine 6, upwards promotes the peanut through the effect of lifting machine 6 until being sent to in the storage fruit case 5.

The walking device 9 is of a crawler-type structure. For the wheel type travelling mechanism, the wheels are high, and the machine body 4 is positioned between the wheels on the two sides, so that the width of the machine body 4 is limited, the internal space of the machine body 4 is limited, and the roller teeth can only be longitudinally placed, so that the length of the machine body is prolonged, and the defects of overlarge turning radius, inconvenient movement and the like are caused. Crawler-type structure height is lower, and fuselage 4 can place in the top of athey wheel, and fuselage 4 width is great, and inside operation space is great to can guarantee that the peanut plucks the fruit comparatively clean thoroughly, shorten automobile body length simultaneously, reduce manufacturing cost, crawler-type structure is for wheeled structure simultaneously, and turning radius is littleer, and is more nimble when the operation in the farmland. Compared with a wheel type structure, the crawler type structure has larger contact area with the ground, and is not easy to sink when the crawler type structure works on soft ground.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
