Description

Technical Field

[0001] The utility model relates to the technical field of sunflower harvesting, in particular to a sunflower stalk leaf beating device. Background Art

[0002] The sunflower harvesting process mainly includes cutting and inserting the sunflower discs, drying, threshing, and screening. Currently, the traditional cutting and inserting process involves sunflower farmers using a sickle to cut the sunflower discs from the sunflower stalks, chopping the tops of the sunflower stalks on the ground into tips, and then inserting the sunflower discs onto the tips of the stalks for drying.

[0003] At present, some sunflower-specific cutting disc inserting machines can realize the cutting disc inserting operation. When the cutting disc inserting machine moves, the sunflower stalks are cut off, the sunflowers are harvested, and finally transported to the rear-end inserting disc. After that, the sunflower discs are collected by sunflower disc harvesting equipment. When the sunflower discs are collected, the leaves are easily collected as well, which increases the impurity rate during threshing. Therefore, it is also necessary to cut off the leaves on the sunflower stalks on the ground. However, the existing equipment lacks equipment for directly removing the leaves, and most of them are supplemented by manual operation. Moreover, the leaves on the sunflower stalks on the ground can also hinder the smooth insertion of the sunflower discs when the cutting disc inserting machine is used. Utility Model Content

[0004] The purpose of the utility model is to provide a sunflower stalk leaf beating device.

[0005] The utility model is implemented by the following technical solutions:

[0006] A sunflower stalk leaf-threshing device comprises a cutting disc inserter, a rotating frame and a flexible rod, wherein the rotating frame is rotatably arranged at the bottom of the cutting disc inserter, and a leaf-threshing drive for driving the rotating frame to rotate is arranged at the bottom of the cutting disc inserter;

[0007] A plurality of flexible rods are staggeredly fixed on the side walls of the rotating frame;

[0008] The rotating frame is composed of a pair of circular side plates and a plurality of connecting rods fixed between the pair of circular side plates;

[0009] One end of the rotating frame is rotatably connected to a connecting plate fixed to the bottom of the cutting disc inserting machine, and the other end of the rotating frame is fixed to an input end of the leaf beating drive fixed to the bottom of the cutting disc inserting machine.

[0010] Preferably, the beating drive is a gear commutator or a motor.

[0011] The advantages of the present invention are as follows: before inserting the sunflower discs, the leaves of the sunflower stalks on the ground are removed by the leaf-beating device of the present invention, so as to prevent the leaves from being mixed with other impurities and being collected by the subsequent equipment for collecting the sunflower discs, thereby increasing the sunflower seed impurities and avoiding obstruction to the insertion of the sunflower discs.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example:

[0018] like Figure 1 、 Figure 2 As shown, a sunflower stalk defoliating device includes a cutting disc inserter 1, a rotating frame 2, and a flexible rod 3. The rotating frame 2 is rotatably arranged at the bottom of the cutting disc inserter 1. The rotating frame 2 is composed of a pair of circular side plates 2.1 and a plurality of connecting rods 2.2 fixed between the pair of circular side plates 2.1.

[0019] A threshing drive 4 for driving the rotating frame 2 to rotate is provided at the bottom of the cutting disc inserting machine 1. The threshing drive 4 is a gear commutator or a motor. In the drawings of this embodiment, a gear commutator is selected. The input end of the gear commutator can be connected to the power shaft of the cutting disc inserting machine 1 through a sprocket and a chain transmission.

[0020] Several flexible rods 3 are staggeredly fixed on the side wall of the rotating frame 2, and the flexible rods 3 are fixed on the connecting rods 2.2. The flexible rods 3 are made of tough metal rods, chains or ropes. The sunflower rods on the ground are of high hardness and there is no need to worry about them being broken.

[0021] One end of the rotating frame 2 is rotatably connected to the connecting plate 5 fixed at the bottom of the cutting disc inserter 1, and the other end of the rotating frame 2 is fixed to the input end of the leaf beating drive 4 fixed at the bottom of the cutting disc inserter 1.

[0022] Working principle: when the rotating frame 2 is powered by a gear commutator or a motor to rotate, the flexible rod 3 is used to swing and knock off the leaves of the sunflower stalks on the ground; the leaf-beating device of the present application can be set as a pair of two, which are arranged below the conveying unit of the cutting disc inserting machine 1 and at the front end of the disc inserting unit. The sunflower planting method suitable for this application is to plant multiple groups side by side, each group consists of two rows of sunflowers, and each row is arranged with a number of sunflowers at intervals. The two rotating frames 2 are located on both sides of a group of two rows of sunflowers when moving. The flexible rods 3 on the two rotating frames 2 can swing to the leaves of the two adjacent rows of sunflower stalks. In this way, in addition to knocking off the leaves on the side of the adjacent sunflower stalks, the leaves on the other side of the adjacent sunflower stalks in the same group can also be hit, so that the leaves of the sunflower stalks on the ground can be knocked off as much as possible.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
