[0002] Alfalfa is the general name for plants of the genus Alfalfa, native to Europe and America. Alfalfa is a perennial forage grass of the Leguminosae family, widely distributed in Northeast my country and North China. It is an excellent forage resource. Alfalfa contains rich alfalfa polysaccharides, soybean flavonoids and isoflavones, as well as a variety of unknown growth factors (UGF). Therefore, alfalfa has physiological functions in livestock and poultry production, such as improving livestock and poultry production performance, improving livestock and poultry immunity, improving livestock and poultry antioxidants, improving livestock and poultry meat quality, and regulating intestinal microecological balance. It is widely used in pig production.

[0003] At present, alfalfa is mostly harvested by manually holding a cutting knife. This operation method requires a lot of manpower, thereby reducing the harvesting efficiency of alfalfa.

[0004] Therefore, we provide a kind of automatic alfalfa cutting equipment to solve the above-mentioned problems. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For specific embodiment 1, please refer to Figure 1-5The utility model is an automatic alfalfa cutting device, comprising a support plate 1 and a handle 2 fixed on the side of the support plate 1; a driving assembly is symmetrically arranged on the bottom surface of the support plate 1; a worm 3 is arranged on a driving assembly; a worm wheel 4 meshing with the worm 3 is rotatably arranged on the bottom surface of the support plate 1; a driving gear 5 is rotatably arranged on the surface of the support plate 1; the driving gear 5 is fixedly connected to the worm wheel 4; a driven gear 6 meshing with the driving gear 5 is rotatably arranged on the surface of the support plate 1; a rotating drum 7 coaxial with the driven gear 6 is fixed on the surface of the driven gear 6; a positioning ring 8 is arranged on the side surface of the rotating drum 7; and a plurality of cutting blades 9 are evenly fixed on the side surface of the positioning ring 8.

[0029] The operation process of this embodiment is: first, put the device where cutting is required, manually push the handle 2 to drive the support plate 1 to move, and then drive the driving component to operate, and then drive the worm 3 to work, and then the worm wheel 4 to rotate, and then drive the driving gear 5 to rotate, and then the driven gear 6 and the rotating drum 7 to rotate, and then drive the positioning ring 8 and the cutting blade 9 to rotate. At this time, the cutting blade 9 can cut alfalfa. The rotation of the cutting blade 9 is completed by using the thrust of the device, which saves cost and manpower.

[0030] For specific embodiment 2, please refer to Figure 1-5 On the basis of the first specific embodiment, the driving assembly includes a connecting plate 10 symmetrically fixed on the bottom surface of the support plate 1; a rotating shaft 11 is rotatably arranged between the two connecting plates 10; wheels 12 are fixed at both ends of the rotating shaft 11, and the worm 3 is fixed on the side surface of the rotating shaft 11.

[0031] Specifically, a dustproof plate 13 is fixed to the surface of the support plate 1 ; under the action of the dustproof plate 13 , impurities can be prevented from falling onto the surfaces of the driving gear 5 and the driven gear 6 ; the rotating drum 7 rotates in cooperation with the dustproof plate 13 .

[0032] Furthermore, the surface of the dustproof plate 13 is symmetrically fixed with limit rods 14 on both sides of the rotating drum 7; a dust removal plate 15 is rotatably arranged on the side of the rotating drum 7; the dust removal plate 15 is slidably matched with the two limit rods 14; and a dust removal groove 16 is opened through the side of the dust removal plate 15.

[0033] Furthermore, a plurality of positioning holes 17 are evenly formed on the side surface of the rotating drum 7; the positioning ring 8 is fixed to the positioning hole 17 by means of fastening bolts; the positioning ring 8 is rotatably matched with the dust removal groove 16; under the action of the dust removal groove 16, impurities on the surface of the cutting blade 9 can be scraped off.

[0034] The operation process of this embodiment is as follows: before cutting, the positioning ring 8 is adjusted to a suitable position according to the length of alfalfa to be cut, and then the positioning ring 8 is fixed to the corresponding positioning hole 17 with a fastening bolt. At this time, the positioning ring 8, the cutting blade 9 and the dust removal plate 15 cannot move up and down, and the dust removal plate 15 cannot rotate under the action of the limit rod 14. When the device is pushed, the wheel 12 rotates, thereby driving the rotating shaft 11 to rotate, thereby driving the worm 3 to rotate, thereby driving the worm wheel 4 to rotate and driving the driving gear 5 to rotate, thereby driving the driven gear 6 and the rotating drum 7 to rotate, thereby driving the positioning ring 8 and the cutting blade 9 to rotate. When the cutting blade 9 enters the dust removal groove 16 on the dust removal plate 15, impurities such as juice and soil on the cutting blade 9 will be scraped off, and the rotation of the cutting blade 9 is realized by driving the wheel 12 to rotate. At the same time, the impurities on the cutting blade 9 are scraped off to the surface of the dustproof plate 13 through the dust removal groove 16, which also prevents the impurities from falling on the driving gear 5 and the driven gear 6, thereby affecting the rotation efficiency.

[0035] For specific embodiment 3, please refer to Figure 1-5 On the basis of the specific embodiment 1 and the specific embodiment 2, a plurality of weight-reducing grooves 18 are formed through the surface of the support plate 1; a plurality of anti-skid teeth 19 are evenly fixed on the side surfaces of the wheels 12; and a positioning assembly is symmetrically provided on the bottom surface of the support plate 1.

[0036] Specifically, the positioning assembly includes a positioning plate 20 fixed to the bottom surface of the support plate 1 and a fixing plate 21; a positioning groove 22 is formed through the side of the positioning plate 20; a positioning frame 23 is slidably provided on the inner wall of the positioning groove 22; and a positioning spring 24 is connected between the fixing plate 21 and the positioning frame 23.

[0037] Furthermore, a collection box 25 is placed on the surface of the support plate 1 ; the side surfaces of the collection box 25 are symmetrically provided with plug-in slots 26 which are respectively plugged and matched with the two positioning frames 23 .

[0038] The operation process of this embodiment is as follows: in order to facilitate the collection of finished products while cutting, the collection box 25 is fixed on the surface of the pallet 1 and positioned by the positioning assembly. The specific operation is first manually pulling the positioning frame 23 outward along the positioning groove 22 so that the positioning spring 24 is stretched, and then the collection box 25 is placed on the surface of the pallet 1, and then let go. At this time, the elastic force of the positioning spring 24 pulls the positioning frame 23 back and finally makes the positioning frame 23 inserted into the insertion groove 26 on the collection box 25. At this time, the collection box 25 is fixed to prevent the collection box 25 from falling during the pushing process.
