In general, the present application is an integrated equipment capable of digging and uprooting peanuts, which can facilitate the drying of the fruits on the peanut plant in use, and has high working efficiency and low labor intensity compared with the manual uprooting method.

[0036] Specifically, the uprooting device 3 is arranged as follows: Figures 1 to 9 As shown in the drawings, the uprooting device 3 comprises a first rotating shaft 31A horizontally arranged and arranged opposite to the clamping conveying channel, both ends of the first rotating shaft 31A are in rotating connection with the rack 5, and the first rotating shaft 31A is in transmission connection with the gearbox 7, specifically, Figure 1As shown, the first rotating shaft 31A is in transmission connection with the output shaft of the gearbox 7 through a gear transmission mechanism and a belt transmission mechanism, that is, the seedling turning device 3 can rotate under the driving of the gearbox 7. A plurality of fixed plates 32A are fixedly connected to the first rotating shaft 31A and are equidistantly distributed along the circumference of the first rotating shaft 31A. A seedling turning drum 33A with open ends is fixedly sleeved between the plurality of fixed plates 32A. A plurality of groups of telescopic rods 34A are installed on the first rotating shaft 31A between every two adjacent fixed plates 32A, are equidistantly distributed along the length direction of the first rotating shaft 31A, and are arranged side by side. The plurality of groups of telescopic rods 34A are connected through a connecting rod 35A, that is, the plurality of groups of telescopic rods 34A can synchronously stretch and retract. Each group of telescopic rods 34A is radially parallel to the seedling turning drum 33A. The end of each group of telescopic rods 34A away from the first rotating shaft 31A is a telescopic end. The telescopic end of each group of telescopic rods 34A penetrates the seedling turning drum 33A through a notch 33A1 formed in the seedling turning drum 33A. The telescopic end of each group of telescopic rods 34A is also installed with a U-shaped shift fork 36A capable of penetrating the notch 33A1. The telescopic rods 34A at both ends of the first rotating shaft 31A are also installed with pulleys 37A. The seedling turning drum 33A is provided with a slide rail fixed plate 38A at both ends. The slide rail fixed plate 38A is located on the side of the first rotating shaft 31A away from the clamping conveying channel. Each slide rail fixed plate 38A is fixedly connected to the rack 5 through the mounting plate 30A. The inner side of each slide rail fixed plate 38A is also installed with a U-shaped slide rail 39A. The U-shaped opening of the U-shaped slide rail 39A faces the first rotating shaft 31A. The specific arrangement mode of the U-shaped slide rail 39A is as shown in Figure 4 As shown, when the pulley 37A rotates to the side of the seedling turning drum 33A away from the conveying device 1, the pulley 37A will respectively enter the U-shaped slide rail 39A and slide along the U-shaped slide rail 39A. The telescopic rod 34A will drive the U-shaped shift fork 36A to retract into the seedling turning drum 33A.

[0037] Specifically, in use, the first rotating shaft 31A in the seedling turning device 3 can rotate under the driving of the gearbox 7, so that the seedling turning drum 33A rotates to the side of the conveying device 1 away from the clamping conveying channel, and the seedling turning drum 33A is in the retracted state. Figure 9For example, the first rotating shaft 31A rotates clockwise, and the first rotating shaft 31A can drive the seedling turning roller 33A, the telescopic rod 34A and the U-shaped fork 36A to rotate synchronously during rotation. When the U-shaped fork 36A rotates to a position close to the clamping conveying channel, the pulleys 37A located at the position are respectively located outside the U-shaped slide rail 39A. At this time, the telescopic rod 34A is in an extended state, and the U-shaped fork 36A is located outside the seedling turning roller 33A. In this way, the U-shaped fork 36A can pick up and capture the peanut plants conveyed through the clamping conveying channel. Then, when the seedling turning roller 33A and the U-shaped fork 36A continue to rotate, the peanut plants can be turned over by 180 degrees. After the peanut plants are turned over, when the U-shaped fork 36A rotates to a position away from the clamping conveying channel, the pulleys 37A located at the position abut the inner walls of the U-shaped slide rail 39A and slide along the U-shaped slide rail 39A. At this time, the telescopic rod 34A will be shortened to drive the U-shaped fork 36A to retract into the seedling turning roller 33A. In this way, the peanut plants can be released, so that the peanut plants fall into the field, thereby completing the turning over operation of the peanut plants. At this time, the fruits on the peanut plants are upward, which is convenient for drying.

[0038] The telescopic rod 34A is specifically provided as follows: as shown in Figures 4 to 7 each group of telescopic rods 34A includes a fixed rod 34A1 parallel to the radial direction of the seedling turning roller 33A. One end of the fixed rod 34A1 is fixedly connected with the rotating shaft 31A, and a sleeve 34A2 is sleeved and slidably connected with each fixed rod 34A1. The end of the sleeve 34A2 away from the first rotating shaft 31A is provided with the U-shaped fork 36A. The first spring 34A3 located in the sleeve 34A2 is arranged between the U-shaped fork 36A and the fixed rod 34A1. The pulley 37A is arranged on the sleeve 34A2 located at both ends of the seedling turning roller 33A. The connecting rod 35A is fixedly connected with the sleeve 34A2. Specifically, when the pulley 37A enters the U-shaped slide rail 39A and slides along the U-shaped slide rail 39A, the sleeve 34A2 will slide along the fixed rod 34A1 synchronously under the action of the connecting rod 35A, and the U-shaped fork 36A will compress the first spring 34A3. In this way, the U-shaped fork 36A can retract into the seedling turning roller 33A. When the pulley 37A slides out of the U-shaped slide rail 39A, the U-shaped fork 36A can synchronously penetrate the seedling turning roller 33A through the gap 33A1 under the action of the first spring 34A3 and the connecting rod 35A.

[0039] Further, as shown in Figures 1 to 4 , as shown in Figure 8 and Figure 9As shown in the figure, two symmetrically distributed flow guide plates 10 are arranged between the clamping conveying channel and the seedling turning roller 33A, both of which are fixedly connected with the frame 5, and between which an open-ended flow channel is formed, the opening of one end of the flow channel close to the seedling turning roller 33A is smaller than that of the other end, so that the peanut plants conveyed in the clamping conveying channel can be conveniently fed into the seedling turning roller 33A; in addition, two symmetrically distributed flow guide plates 9 are arranged above the seedling turning roller 33A, both of which are fixedly connected with the frame 5 through mounting rods 91, and between which an open-ended flow channel is formed, the opening of one end of the flow channel away from the clamping conveying channel is smaller than that of the other end, so that when the seedling turning roller 33A turns the peanut plants, the two flow guide plates 9 can fold and turn the peanut plants.

[0041] Specifically, in use, the second rotating shaft 31B in the seedling turning device 3 can rotate under the driving of the gearbox 7, so that the U-shaped elastic tooth 34B can be driven to rotate and move along the guide groove, and the U-shaped elastic tooth 34B can be driven to rotate and move along the guide groove. Figure 13For example, the second rotating shaft 31B rotates counterclockwise, and in the process of rotation, the second rotating shaft 31B can drive the mounting disc 32B and the U-shaped elastic tooth 34B to rotate, and under the action of the rotating rod 33B and the connecting rod 35B, the guide wheel 36B can slide along the guide groove. When the U-shaped elastic tooth 34B rotates to a position close to the clamping conveying channel, the guide wheels 36B at this position are located in the arc-shaped guide groove and slide along the arc-shaped guide groove, at this time, the two ends of the U-shaped elastic tooth 34B are located outside the shell 38B through the arc-shaped gap 38B1, so that the U-shaped elastic tooth 34B can pick up and capture the peanut plants conveyed through the clamping conveying channel, and then in the process of continuous rotation of the U-shaped elastic tooth 34B, under the cooperation of the shell 38B, the peanut plants can be turned over by 180 degrees.
