[0001] This utility model relates to the field of agricultural machinery technology, specifically to a chaff cutter with adjustable forage cutting length. Background Technology

[0002] Forage grass refers to grasses or other herbaceous plants used to feed livestock, primarily as animal feed. Forage grass includes cultivated forage grass, wild forage grass, and straw feed. The definition of forage grass can be further subdivided into annual and perennial grasses, cool-season and warm-season grasses based on suitable growing temperature, and family-based grasses such as Poaceae, Leguminosae, and Asteraceae. The characteristics of forage grass include vigorous growth, tender texture, high yield per unit area, strong regeneration ability, multiple harvests per year, good palatability for livestock, and rich nutrition, containing high-quality protein, phosphorus, calcium, and vitamins. These characteristics make forage grass a preferred feed for livestock.

[0003] Before ensiling, forage needs to be cut into uniform lengths to ensure consistent quality. However, existing forage cutting equipment typically relies on visual estimation, making it difficult to accurately control the cut lengths. As a result, the cut forage still varies in length, which is not conducive to subsequent ensiling.

[0004] Therefore, we propose an adjustable forage cutter to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1 - Figure 3 An adjustable hay cutter includes a working panel 1 and a cutter 3 mounted on the working panel 1. The working panel 1 has grooves 11 on both side walls. An adjustment mechanism 2 is mounted on the working panel 1. The adjustment mechanism 2 includes a threaded rod 21 rotatably connected between the inner walls of the grooves 11. A movable block 22 is threaded onto the threaded rod 21. A connecting rod 23 is fixedly mounted between the two side walls of the upper end of the movable block 22. The cutter 3 is rotatably connected to the connecting rod 23. A scale strip 5 is fixedly mounted on one side wall of the working panel 1, and a pointer 24 is fixedly mounted on the side wall of the movable block 22.

[0022] In this embodiment: When using the device to cut hay, the position of the guillotine 3 can be adjusted by rotating the threaded rod 21. When the threaded rod 21 rotates, it drives the movable block 22 connected to it to slide along the slide groove 11. When the movable block 22 moves, it drives the upper guillotine 3 and the pointer 24 on the side to move along the direction of the slide groove 11. By observing the position of the pointer 24, the distance between the guillotine 3 and the side wall of the working panel 1 can be known. When the position is adjusted to a suitable position, the hay is piled on the working panel 1 and the hay is cut by rotating the guillotine 3. In actual use, the position of the guillotine 3 can be adjusted according to the needs of the adjustable hay cutting length guillotine, so that the length of the cut hay can be adjusted at will and is easy to control.

[0023] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 Handles 27 are fixedly installed at both ends of the threaded rod 21. Limiting grooves 12 are opened in both sliding grooves 11. The inner walls on both sides of the lower end of the limiting groove 12 are arc-shaped. The inner walls on both sides of the lower end of the movable block 22 are also arc-shaped. The arc-shaped design allows the hay to fall directly downwards after it falls into the sliding groove 11, avoiding the hay from accumulating in the limiting groove 12 and affecting the movement of the device.

[0024] A connecting plate 25 is fixedly installed on the side of each of the two movable blocks 22. A tool holder 26 is fixedly installed between the two connecting plates 25. When the movable block 22 on one side is rotated and moved by the threaded rod 21, it can simultaneously move the movable block 22 in the slide groove 11 on the other side.

[0025] The lower blade of the chaff cutter 3 is slidably connected to the blade holder 26. Both sides of the blade holder 26 are curved surfaces. The blade holder 26 is slidably connected to the working panel 1. The curved surface of the blade holder 26 facilitates the advancement of hay.

[0026] A limiting structure 4 is provided on one side wall of the work panel 1. The limiting structure 4 includes a fixing rod 41 fixedly installed on the upper wall of both sides of the work panel 1. A limiting block 42 is fixedly installed on the upper end of both fixing rods 41. The fixing rods 41 are fixedly set on the same side of the work panel 1.

[0027] Connecting blocks 43 are slidably installed on both fixed rods 41, and a movable baffle 44 is fixedly installed between the two connecting blocks 43. The movable baffle 44 can help limit the movement of the hay and block the hay during cutting. After cutting, the hay can be discharged outward from the movable baffle 44.

[0028] In this embodiment: when using the device to cut hay, the threaded rod 21 can be rotated in the groove 11 by turning the handle 27. When the threaded rod 21 rotates, it can drive the movable block 22 to slide along the groove 11. When the movable block 22 moves, it can simultaneously drive the chaff cutter 3 and the side pointer 24 to move. When the movable block 22 moves, it can drive the blade holder 26 to slide along the inner surface of the working panel 1 through the connecting plate 25 on the side. When the blade holder 26 moves, it can drive the movable block 22 on the other side to slide along the groove 11. When hay falls into the groove 11, the hay can slide along the groove 11. The grass falls downwards from the arc-shaped surface at the lower end of the limiting groove 12 and the movable block 22 into the sliding groove 11, which can prevent the grass from accumulating in the limiting groove 12 and affecting the normal movement of the chaff cutter 3. Before cutting the grass, the grass can be neatly stacked on the working panel 1, with one side against the movable baffle 44. The grass can then be cut by rotating the chaff cutter 3. After cutting, the grass can be pushed out of the working panel 1 by pulling the movable baffle 44 upwards. When using this device, the grass can be prevented from falling into the sliding groove 11 on the side and affecting the movement of the device. The movable baffle 44 facilitates the control of the grass length.
