Technical Field

[0001] The utility model relates to the technical field of forage grass spreading equipment, in particular to a forage grass spreading machine. Background Art

[0002] The forage spreader is a feeding equipment specially used in agricultural and animal husbandry breeding areas, large and medium-sized farms and standardized community farms.

[0003] Its main function is to complete the feeding process by spreading the finished ration directly into the feeding area.

[0004] The forage spreader mainly consists of two parts: a motor vehicle and a spreading system. The motor vehicle is mainly responsible for transportation and providing power for spreading, while the spreading system completes feeding through the main conveyor and small conveyor. When the spreader arrives at the designated feeding place, the operator will first turn on the small conveyor control switch on the instrument, then turn on the large conveyor and start the spreader to feed at the same time.

[0005] In the prior art, since the hay is generally in bundles, the hay bundles need to be manually separated before spreading, but the hay bundles are generally pressed hard, so it takes a long time to separate the hay bundles. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a forage spreader so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] Furthermore, the inner arc surfaces of the first arc frame and the second arc frame face oppositely, and a rotating roller is rotatably mounted on one end of the first arc frame and the second arc frame away from the mounting shaft.

[0010] Furthermore, the stretching mechanism includes a first rotating rod and a second rotating rod, the first rotating rod is rotatably mounted on the inner side of the first arc frame, the second rotating rod is rotatably mounted on the inner side of the second arc frame, and the first rotating rod and the second rotating rod are commonly connected to a plurality of stretching springs.

[0011] Furthermore, a protrusion is provided on one side of the U-shaped platform, a sliding material tray is provided below the protrusion, and mounting rods fixedly connected to the U-shaped platform are provided on both sides of the sliding material tray.

[0012] Furthermore, the outer surface of the conveyor belt is provided with a plurality of cutting fins.

[0013] Furthermore, a spring push rod rotatably connected to the U-shaped platform is provided on one side of the connecting frame.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. The forage spreader rotates the round grass bale by the movement of the conveyor belt, and because the first arc frame and the second arc frame abut against the outer surface of the round grass bale, when the conveyor belt moves upward, the grass on the surface of the round grass bale will be scraped out and discharged by the conveyor belt, and the carried out grass will fall along the side of the U-shaped platform, thereby achieving the effect of evenly dismantling the grass bale, and the round grass bale can be directly used for scattering forage, which effectively improves the applicability and convenience of the device;

[0016] 2. This forage spreader, through the arrangement of the first rotating rod and the second rotating rod, connects the two ends of the tension spring to the first arc frame and the second arc frame respectively, so that the rotating rollers at the ends of the two arc frames can contact the outer surface of the round hay bale, thereby increasing the pressure between the round hay bale and the conveyor belt, so that the conveyor belt can scrape the hay on the surface of the round hay bale, and effectively avoids the problem of uneven spreading caused by the gradual reduction of the round hay bale.

[0026] In this embodiment, the U-shaped platform 3 is installed by setting the fixing rod 2 and the fixing frame 1. When the device is used, the round grass bale is placed inside the U-shaped platform 3, and the round grass bale is pressed against one side of the U-shaped platform 3 by setting the connecting frame 5 and the two arc frames. The round grass bale is rotated by moving the conveyor belt 4. Since the first arc frame 7 and the second arc frame 8 are in contact with the outer surface of the round grass bale, when the conveyor belt 4 moves upward, the grass on the surface of the round grass bale will be scraped out and discharged by the conveyor belt 4, and the grass brought out will fall along the side of the U-shaped platform 3, thereby achieving the effect of evenly dismantling the grass bale, and the round grass bale can be directly used for scattering forage, which effectively improves the applicability and convenience of the device. By setting the stretching mechanism 9, when the round grass bale gradually becomes smaller, the ends of the first arc frame 7 and the second arc frame 8 can always apply pressure to the round grass bale to avoid the problem of uneven spreading caused by the gradual shrinkage of the round grass bale.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the outer surface of the conveyor belt 4 is provided with a plurality of cutting fins 11 .

[0034] In this embodiment, the provision of the cutting fins 11 improves the convenience of the conveyor belt 4 in scraping the hay from the surface of the round hay bale, thereby achieving the purpose of improving the efficiency of hay discharge.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a spring push rod 12 rotatably connected to the U-shaped platform 3 is provided on one side of the connecting frame 5 .

[0036] In this embodiment, the spring push rod 12 is provided to provide thrust to the connecting frame 5, thereby increasing the pressure of the first arc frame 7 and the second arc frame 8 on the round hay bale, so as to facilitate the scraping of hay on the surface of the round hay bale through the conveyor belt 4.
