Technical Field
[0001] This utility model relates to the technical field of a new type of yam excavator, and in particular to a new type of yam excavator. Background Technology
[0002] Yam, a very common vegetable and medicinal herb in daily life, is highly valued for its unique properties. The root and stem of this plant can not only be eaten as food, but also has a mild and pleasant taste, a delicate and smooth texture, providing a delightful mouthfeel. More importantly, yam is rich in starch and various nutrients beneficial to the human body, such as vitamins, minerals, and dietary fiber, giving it high nutritional value.
[0003] In the theoretical system of Traditional Chinese Medicine, yam holds an important medicinal position. It is believed to tonify the spleen and lungs, effectively enhancing the digestive and absorptive functions of the spleen and stomach, while also nourishing the lungs and improving the health of the respiratory system. Furthermore, yam is widely used for nourishing yin and beautifying the skin, helping to regulate the body's yin-yang balance, keeping the skin moisturized and smooth, and delaying aging.
[0004] A yam harvester is an agricultural machine specifically designed to dig up yams grown underground. This machine can improve the efficiency of yam harvesting and reduce the labor intensity for farmers.
[0005] Existing equipment is highly destructive when digging yams, causing economic losses and waste. To overcome these disadvantages, this invention provides a novel yam digging machine. Utility Model Content

[0008] Furthermore, the fixing component includes a pin disposed on the first pin hole, and one end of the pin is provided with a tension thread.
[0009] Furthermore, a hexagonal nut is threaded onto the tension thread.
[0010] Furthermore, the propulsion assembly includes a hydraulic cylinder fixedly connected to the hydraulic hole, a push plate fixedly connected to the output end of the hydraulic cylinder, and limit holes are opened on both the left and right sides of the top of the support plate, with limit components provided on the limit holes.

[0012] Furthermore, an excavator connecting frame is fixedly connected to the top of the support plate.
[0013] Furthermore, the first pin hole and the second pin hole are fixed together by a fixing component.
[0014] The beneficial effects of this utility model are:
[0015] In use, this novel yam excavator adjusts the width of the device by sliding a connecting plate on a connecting groove, thereby excavating yams at different intervals without damaging them. The conical rods on both sides are inserted into the soil to dig out the soil and yams together, and then the yams are pushed out of the excavator by a propulsion component, which is convenient for manual operation. The device can be connected to the excavator by an excavator connecting frame, which facilitates the movement and operation of the device. Attached Figure Description
