On the transmission rod, one end of the telescopic rod is hinged to the eccentric wheel through a bearing, and the other end is fixedly connected to the lower support rod.

In the vibrating sieve type potato excavator, the limit mechanism includes a limit wheel set on the wheel frame, the guide rod is connected with the limit wheel beam frame through the guide rod sleeve, and the width of the limit wheel can be adjusted; In the chute of the rack, it can be adjusted up and down.

In the vibrating screen potato excavator, the digging shovel assembly includes a digging shovel between the left and right shovel handles, the left and right shovel handles are fixedly connected to the left side plate and the right side plate, and the separating screen, side The guard plate is fixedly connected with the digging shovel.

In the vibrating screen potato excavator, the swing mechanism includes an upper support rod fixed in the conduit of the frame, and the upper support rod and the lower support rod are respectively hinged to the left side plate and the right side plate.

The beneficial effects of the utility model are: simple structure, complete functions, can conveniently adjust the digging shovel entry angle and vibration amplitude according to the soil condition, reduce working resistance, and improve the adaptability of the excavator; matching walking tractor is suitable for terraced fields and hills Potato harvesting operations in small plots such as mountains replace traditional excavation by human and animal power, which reduces labor intensity and liberates labor.

Detailed ways:

Below in conjunction with the best examples shown in the accompanying drawings for further details:

Embodiment 1: see Fig. 1, a kind of vibrating screen type potato excavator comprises frame 1, and the gear of power transmission mechanism 2 is located in frame 1 gearbox 1-1; Clutch 4 is located on frame 1; The guide rod 3-3 of the limit mechanism 3 is located in the chute 1-2 of the frame 1; the upper pole 6-1 of the swing mechanism 6 is connected with the conduit 1-4 of the frame 1; the shovel of the excavating shovel assembly 5 The handle 5-3 is fixedly connected with the left side plate 6-3 and the right side plate 6-4 of the swing mechanism 6.

Described frame 1 comprises gear box 1-1, is provided with chute 1-2 on gear box 1-1, is provided with connecting arm 1-3, conduit 1-4 on both sides of gear box 1-1 Set at the end of connecting arm 1-3.

The power transmission mechanism 2 includes a sliding gear 2-1 connected on the transmission rod 2-2, the bearing is arranged on the transmission rod 2-2, and is arranged on the gear box 1-1 of the frame 1, and the eccentric wheel Connected on the transmission rod 2-2 by a key, one end of the telescopic rod 2-4 is hinged with the eccentric wheel 2-3 through a bearing, and one end is fixedly connected with the lower support rod 6-2.

Described limit mechanism 3 comprises limit wheel 3-1 and is located on the wheel frame 3-5, and guide rod 3-3 is connected with limit wheel beam frame 3-2 through guide rod sleeve 3-4, and can adjust limit Wheel width; Guide bar 3-3 is located in the chute 1-2 of frame 1, can adjust up and down.

Described excavating shovel assembly 5 comprises and is provided with excavating shovel 5-1 between left and right shovel handle 5-3, and left and right shovel handle 5-3 is fixed with left side plate 6-3, right side plate 6-3. Then, the separating screen 5-2, the side guard plate 5-4 are fixedly connected with the digging shovel 5-1.
