Description

Technical Field

[0001] This utility model relates to the field of chaff cutting equipment technology, and in particular to a chaff cutting machine. Background Technology

[0002] Forage choppers are mainly used for chopping crop stalks and forage. The chopped stalks are mostly roughage, making them suitable for livestock farmers such as cattle and sheep. Forage choppers are available in two types: electric motor and diesel engine trailers. They can also be equipped with gasoline engines or diesel engines. Currently, most forage choppers on the market use a belt to connect the power pulley and the cutter head pulley, thus inputting power to the cutter head. Belts are prone to damage during high-speed transmission, so they need to be replaced. Existing forage choppers replace the belt by using the belt's elasticity and applying brute force to stretch the belt, causing it to fit onto the two pulleys. This method of replacement is time-consuming, labor-intensive, and inconvenient.

[0003] Therefore, there is a need for a chaff cutter that allows for easy belt replacement, making belt replacement more convenient. Utility Model Content

[0021] The following will describe specific embodiments and appendices. Figure 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] A chaff cutter includes a frame 1 with a rectangular front end and a triangular rear end. A machine frame 2 is fixedly connected to the rear end of the frame 1, which is used to mount the chaff cutting device. A sliding frame 3 is slidably connected to the frame 1, and a drive motor 31 is fixedly connected to the sliding frame 3. The drive motor 31 is connected to the chaff cutting device via a belt 4, and the drive motor 31 drives the chaff cutting device to move, thus realizing the chaff cutting action. Two movable wheels 11 are rotatably connected to the rear end of the frame 1, and a support wheel 12 is rotatably connected to the front end of the frame 1. The movable wheels 11 enable the device to move quickly, and the support wheel 12 and the movable wheels 11 provide three points for the device to stand stably. A telescopic support frame 13 is fixedly connected to the front end of the frame 1, which is used to adjust the height of the device when it is connected to a traction machine, so that the device can be towed and moved easily.

[0023] The sliding frame 3 is slidably connected to the frame 2. Both ends of the sliding frame 3 are provided with pads 33 and limiting plates 34. The pads 33 and limiting plates 34 are fixed to the sliding frame 3 with bolts. The pads 33 create a clamping gap between the sliding frame 3 and the limiting plates 34, clamping the sliding frame 3 to the left and right sides of the frame 1 through this gap, thus achieving a sliding connection between the sliding frame 3 and the frame 1, preventing the sliding frame 3 from detaching from the frame 1. A driven shaft is rotatably connected to the frame 2, and a blade and a cutter head pulley 21 are fixedly connected to the driven shaft. A first pulley groove is formed on the cutter head pulley 21. A power pulley 32 is fixedly connected to the output end of the drive motor 31, and a second pulley groove is formed on the power pulley 32. The power pulley 32 and the cutter head pulley 21 are connected by a belt 4. The first and second pulley grooves are used to limit the belt 4, preventing it from detaching during operation.

[0024] The sliding frame 3 is rotatably connected to one end of an adjusting plate 5 on the side near the frame 2. The adjusting plate 5 is in a vertical state. An adjusting rod 51 is rotatably connected to the other end of the adjusting plate 5. The adjusting rod 51 can rotate freely relative to the adjusting plate 5. The adjusting rod 51 is rotatably connected to the frame 1 and cannot move. The adjusting plate 5 is arc-shaped. The end of the adjusting plate 5 near the adjusting rod 51 has a bent section. The bent section protrudes upward and bends. When the adjusting rod 51 rotates, it drives the rotating connection position of the adjusting rod 51 and the adjusting plate 5 to rotate together around the axis of the adjusting rod 51. The existence of the bent section allows the connection position of the adjusting plate 5 and the adjusting rod 51 to move further towards the position of the frame 2, so that the sliding frame 3 can be as close to the frame 2 as possible, which facilitates the replacement of the belt 4.

[0025] The frame 1 has mounting slots 14 on both sides. U-shaped supports 15 are fixedly connected to the mounting slots 14 by bolts. The adjusting rod 51 is rotatably connected to the U-shaped support 15. The U-shaped support 15 can be finely adjusted in the mounting slots 14, so that the relative position of the adjusting rod 51 and the frame 2 changes. This allows the distance between the cutter head pulley 21 and the power pulley 32 to change, so that the device can install belts 4 of different lengths and sizes, increasing the adaptability of the device.

[0026] A connecting handle 22 is fixedly connected to one side of the frame 2. The connecting handle 22 passes through the belt 4 ring. A protective cover 23 is fixedly connected to the other end of the connecting handle 22. The protective cover 23 partially covers the outer ring of the cutter head pulley 21, which can play a protective role and prevent foreign objects from touching the cutter head pulley 21 and the belt 4 in that part and causing danger.

[0027] The telescopic support frame 13 is equipped with an adjustment device, which is existing technology and is a jack structure. A crank is rotatably connected to the top of the telescopic support frame 13. The crank is connected to the adjustment device through a transmission. Its connection structure is also existing technology and will not be described in detail here. Turning the crank can make the jack extend and retract, so that the telescopic support frame 13 can extend to support the frame 1, which facilitates the connection between the frame 1 and the traction machine.

[0028] A lower housing 24 is fixedly connected to the frame 2. A driven shaft is rotatably connected to the lower housing 24. An upper housing 25 is rotatably connected to one side of the lower housing 24. The upper housing 25 can rotate and open relative to the lower housing 24 to facilitate internal inspection and maintenance. The blade is set on the driven shaft between the upper housing 25 and the lower housing 24. The upper housing 25 has a feed port at the rear end and on both sides, a discharge port at the top, and a discharge port at the rear end of the lower housing 24. This provides feeding and discharging methods for the device to process agricultural materials in various ways.

[0029] A limiting plate 52 is also provided on one side of the frame 1, which can limit the adjustment rod 51 so that it can maintain support after supporting the sliding frame 3 and will not rotate under the elastic force of the belt 4.

[0030] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0031] In this utility model, "upper", "lower", "left", "right", "front" and "back" are relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0032] The above description is merely an example and illustration of the structure of this utility model.
