Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato receivers, in particular to a chain-type sweet potato receiver. Background Art

[0002] The chain-type sweet potato harvester is a mechanical equipment specially used for harvesting sweet potatoes. The chain-type sweet potato harvester digs sweet potatoes through chain transmission. This machine is usually driven by a hand tractor or a four-wheel tractor. The chain transmission system can effectively transmit power to the digging device, thereby realizing the digging and collection of sweet potatoes.

[0003] When the chain-type sweet potato harvester is in use, the tillage plow digs the sweet potatoes out of the soil, and the dug sweet potatoes are transported by the soil-dividing chain, and finally the sweet potatoes are spread on the ground. When the tillage plow is used for a long time, the front end of some tillage plows is prone to wear, resulting in a greatly reduced tillage effect. Most tillage plows are welded to the connecting rod, and the connecting rod is fixed to the frame with bolts and nuts. Therefore, when the tillage plow needs to be replaced, it can only be replaced as a whole. However, this replacement is more wasteful of raw materials, and the replacement operation is more cumbersome, resulting in the subsequent inability to use the device in a timely manner. Therefore, in response to the above problems, we proposed a chain-type sweet potato harvester. Utility Model Content

[0004] The purpose of the utility model is to provide a chain-type sweet potato harvester to solve the problem that the front end of some soil-turning plows is easily worn out when used for a long time, resulting in a greatly reduced soil-turning effect. Most soil-turning plows are welded to connecting rods, and the connecting rods are fixed to the frame by bolts and nuts. Therefore, when the soil-turning plow needs to be replaced, it can only be replaced as a whole. However, this replacement is more wasteful of raw materials, and the replacement operation is more cumbersome, resulting in the problem that the device cannot be used in time later.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The transmission mechanism that this second transmission gear is connected with this second transmission gear, and this second transmission gear is connected with this second transmission gear at the outer end of this second transmission gear.

[0007] Preferably, the first transmission wheel is located above the frame, the conveyor belt is located above the frame, the second transmission wheel is located above the frame, and the outer side of the connecting shaft is rotatably connected to the frame.

[0008] Preferably, the upper and lower ends of the first transmission shaft are rotatably connected to the frame, the chain conveyor assembly is located inside the frame, and the upper and lower ends of the second transmission shaft are rotatably connected to the frame.

[0009] Preferably, there are two connecting plates, which are connected to the frame through bolts and nuts, and the connecting rod is located at the right end of the chain conveyor assembly.

[0010] Preferably, there are a number of placement grooves and a number of rubber sleeves, the outer side of the soil plow and the inner wall of the rubber sleeve fit tightly, the screw assembly passes through the connecting rod, the placement groove and the rubber sleeve, and the rear end of the connecting rod is fixedly connected to an internal threaded cap.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, a placement groove, a rubber sleeve, an internal threaded sleeve, a screw assembly, a handle and an internal threaded cap are provided. When the soil plow is worn, the handle is rotated outward, and the handle drives the screw assembly to rotate outward. The screw assembly rotates upward along the internal threaded sleeve, so that the screw assembly first leaves the internal threaded cap and then leaves the internal threaded sleeve, thereby pulling out the severely worn soil plow and then replacing it. The reverse operation can be performed for installation. The device can quickly replace a damaged soil plow without replacing the entire device, thereby saving raw materials, and the operation and replacement are simple, which is convenient for subsequent timely use.
