Bar cutting machine

Abstract

The utility model relates to the technical field of straw smashing, and discloses a straw cutting machine which comprises a machine body, a push handle is fixedly installed on one side of the upper end of the machine body, a straw cutting box is detachably installed on the other side of the upper end of the machine body, the other side of the upper end of the straw cutting box is communicated with a feeding hopper, and the lower end of one side of the straw cutting box is communicated with a discharging channel. According to the technical scheme, the rubber sheet can abut against the outer side of the corn straw, so that the corn straw is driven to move downwards to be fed, when the feeding plate is reset upwards, the rubber sheet makes contact with the reset rod, the reset rod pushes the rubber sheet to rotate outwards, and therefore the rubber sheet is separated from the abutting corn straw, and the corn straw is fed. According to the straw cutting and smashing device, the straw cutting and smashing efficiency of corn straw is improved, the situation that leaves are scratched due to the fact that a worker holds the corn straw for feeding is avoided, the beating rods on the feeding plate can continuously beat the discharging channel in the up-and-down reciprocating movement process of the feeding plate, and therefore the situation that the discharging channel is blocked is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of straw crushing, in particular to a straw cutting machine. Background Art

[0002] Corn is a crop used as both food, cash crop and feed, and corn stalks are also important production resources for industrial and agricultural production. As a resource, corn stalks contain rich nutrients and available chemical components and can be used as raw materials for animal husbandry feed. For a long time, corn stalks have been one of the main raw materials for roughage for livestock.

[0003] When implementing this technical solution, there are at least the following defects: although the existing corn stalk cutting machine can crush corn stalks, it requires manual feeding, and the leaves of the corn stalks are very likely to scratch the workers during the feeding process, and the feeding channel is also very likely to be blocked, which is in urgent need of improvement. Therefore, we propose a stalk cutting machine. Utility Model Content

DETAILED DESCRIPTION

[0024] See also Figure 1-2 The utility model provides a technical solution: a rod cutting machine includes a body 1, a push handle 11 is fixedly installed on one side of the upper end of the body 1, a rod cutting box 12 is detachably installed on the other side of the upper end of the body 1, a feed hopper 13 is connected to the other side of the upper end of the rod cutting box 12, a discharge channel 14 is connected to the lower end of one side of the rod cutting box 12, a servo motor 2 is detachably installed on one side of the upper end of the rod cutting box 12, a winding drum 21 is installed on the output end of the servo motor 2, a pull rope 22 is wound around the outer wall of the winding drum 21, a feed plate 23 is arranged on the upper end of the feed hopper 13, a slider 26 is fixedly installed on one side of the feed plate 23, and a servo motor 2 is detachably installed on one side of the upper end of the rod cutting box 12. The other side of the feed plate 23 is detachably mounted with a knocking rod 3, a reset frame 4 is arranged at the upper end of the feed plate 23, and a plurality of reset rods 5 are fixedly mounted at the lower end of the reset frame 4. The free end of the pull rope 22 passes around the guide wheel and is fixedly connected to the lower end of the feed plate 23, so that the feed plate 23 can be pulled and moved by the pull rope 22. The knocking rod 3 is arranged directly above the discharge channel 14, so that the knocking rod 3 can knock the discharge channel 14. The size of the slider 26 is matched with the size of the slide groove 25, and the slider 26 is slidably connected to the slide groove 25, so that the slider 26 cooperates with the slide groove 25, thereby ensuring the stability of the movement of the feed plate 23.

[0025] A plurality of rubber sheets 24 are provided on one side of the feed plate 23 , and the reset rod 5 corresponds to the rubber sheets 24 one by one. The reset rod 5 cooperates with the rubber sheets 24 , so that the reset rod 5 pushes the rubber sheets 24 to separate from the corn stalks.

[0026] A spring 27 is fixedly installed in the inner cavity of the slide groove 25, and the other end of the spring 27 is fixedly connected to the slider 26, so that the feed plate 23 can be driven to reset through the setting of the spring 27.

[0027] When cutting the stalks, firstly, the corn stalks to be cut are inserted into the feed hopper 13 through the openings of the reset frame 4 and the feed plate 23, and then the servo motor 2 is turned on. The servo motor 2 drives the winding drum 21 to rotate forward and backward periodically, and the winding drum 21 continuously reels and releases the pull rope 22, and then cooperates with the elasticity of the spring 27 to drive the feed plate 23 to move up and down reciprocatingly. When the feed plate 23 moves downward, the rubber sheet 24 will abut against the outside of the corn stalks, thereby driving the corn stalks to move downward for feeding. When the feed plate 23 resets upward, the rubber sheet 24 will contact the reset rod 5. The reset rod 5 pushes the rubber sheet 24 to rotate outward, thereby separating the rubber sheet 24 from the corn stalks it is abutting against. Due to the weight of the corn stalks themselves, the corn stalks will remain in the feed hopper 13. When the feed plate 23 moves downward again, it will push and feed the corn stalks again, thereby improving the efficiency of cutting and crushing the corn stalks, and avoiding the situation where the staff feeds the corn stalks by hand and causes scratches on the blades. At the same time, during the reciprocating movement of the feed plate 23 up and down, the knocking rod 3 on the feed plate 23 will continuously knock on the discharge channel 14, thereby reducing the blockage of the discharge channel 14.
