Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, and in particular to an agricultural rotary tiller. Background Technology

[0002] A rotary tiller is a device used in agriculture to loosen soil. When using a rotary tiller, a fuel engine drives a rotating roller to rotate, and the rotary teeth on the surface of the roller can effectively loosen the soil.

[0003] The inventors discovered in their daily work that rotary tillers still have at least the following problems: When using a rotary tiller, the rotating roller is driven by a fuel engine, so that the rotary teeth on the surface of the rotating roller can loosen the soil well. However, in actual use, because the soil moisture level is different, using a single moving wheel cannot meet most situations. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an agricultural rotary tiller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural rotary tiller, comprising a support frame, an oil tank mounted on the top of the support frame, a fuel engine mounted on the top of the support frame, a handrail provided on the top of the support frame, movable wheels provided at the bottom of the support frame, an arc plate fixedly connected to the bottom of the support frame, rotary tillage teeth provided at the bottom of the support frame, and a fixing device provided at the bottom of the support frame, the fixing device comprising a fixing frame fixedly connected to the bottom of the support frame, the inner wall of the fixing frame slidably connected to the top of the movable wheels, a rectangular groove provided on one side of the fixing frame, a rubber block provided on the inner wall of the rectangular groove, and the rubber block fixedly connected to the top of the movable wheels.

[0006] The effect achieved by the above components is that when using the fixing device, the top of the movable wheel is slid into the inside of the fixing frame, thereby squeezing the rubber block into the inside of the rectangular groove. This makes it easy to set the movable wheel at the bottom of the support frame, and also makes it easy to replace different models of movable wheels.

[0007] Preferably, the bottom of the fixed frame has a notch, and a locking block is slidably connected to the inner wall of the notch. One side of the locking block is fixedly connected to the side of the top of the moving wheel.

[0008] The effect achieved by the above components is that by placing the locking block inside the notch, the connection between the top of the fixed frame and the moving wheel becomes tighter.

[0009] Preferably, a positioning frame is fitted onto the bottom surface of the fixing frame, the positioning frame is located at the bottom of the locking block, and a rubber plate is fixedly connected to one side of the positioning frame.

[0010] The effect achieved by the above components is as follows: after the locking block is slid to the top of the notch, the positioning frame is fitted onto the bottom of the surface of the fixed frame, and then the positioning frame is set at the bottom of the locking block. This can restrict the locking block inside the notch. The rubber plate is set on the side of the fixed frame away from the positioning frame, so that the positioning frame can be restricted to the bottom surface of the fixed frame.

[0011] Preferably, a damping rod is fixedly connected to one side of the fixed frame, and the end of the damping rod away from the fixed frame is fixedly connected to the inner wall of the positioning frame. A spring is sleeved on the surface of the damping rod, and one end of the spring is fixedly connected to one side of the fixed frame, while the end of the spring away from the fixed frame is fixedly connected to the inner wall of the positioning frame.

[0012] The effect achieved by the above components is that the positioning frame is pulled closer to the fixed frame by the spring, which makes it easier to restrict the positioning frame to the surface of the fixed frame.

[0013] Preferably, the adjusting device includes a rotating rod, which is inserted into one side of the top of the support frame. One end of the rotating rod is fixedly connected to a fixing block, and the fixing block is fixedly connected to one end of the handrail.

[0014] The effect achieved by the above components is that when using the adjustment device, the handrail can be rotated well, thus facilitating the adjustment of the height of the top of the handrail, which is convenient for operators of different body types.

[0015] Preferably, a bolt is threaded through one side of the top of the support frame, and a rubber ring is provided at the bottom of the bolt, which is fixedly connected to the surface of the rotating rod.

[0016] The effect achieved by the above components is that when the rotating rod is rotated to the appropriate position, the bolt is manually controlled to rotate, thereby pressing the bolt against one side of the rubber ring, which makes it easier to restrict the rotating rod to one side of the top of the support frame.

[0017] Preferably, a semi-circular plate is rotatably fitted at the bottom of the bolt, and the semi-circular plate is fitted on the top of the rubber ring.

[0018] The effect achieved by the above components is to press the semi-circular plate against the top of the rubber ring, which makes it easier to restrict the bolt to one side of the rubber ring.

[0019] Preferably, a threaded rod is threaded through one side of the support frame, a limiting strip is rotatably sleeved on the top of the threaded rod, a positioning rod is fixedly connected to the bottom of the limiting strip, and the positioning rod is slidably inserted through one side of the support frame.

[0020] The effect achieved by the above components is that the rotation of the threaded rod is manually controlled, and the limiting strip is set at the bottom of the handrail under the restriction of the positioning rod, which can prevent the handrail from rotating downward.

[0021] In this invention, by setting a fixing device, when using the fixing device, the top of the movable wheel is slid into the inside of the fixing frame, thereby squeezing the rubber block into the inside of the rectangular groove. This makes it easy to set the movable wheel at the bottom of the support frame, and also makes it easy to replace different models of movable wheels. Attached Figure Description

[0027] Example 1, such as Figure 1-4 As shown, an agricultural rotary tiller has an oil tank 2 and a fuel engine 3 mounted on the top of a support frame 1. A handrail 4 is also mounted on the top of the support frame 1, and casters 5 are mounted on the bottom of the support frame 1. An arc plate 6 is fixedly connected to the bottom of the support frame 1, and rotary tillage teeth 7 are provided on the bottom of the support frame 1. A fixing device 8 is also provided on the bottom of the support frame 1. When using the rotary tiller, the fuel engine 3 drives the rotating roller to rotate, allowing the rotary tillage teeth 7 on the surface of the rotating roller to effectively loosen the soil.

[0028] Reference Figure 2 and Figure 3The fixing device 8 includes a fixing frame 801, which is fixedly connected to the bottom of the support frame 1. The inner wall of the fixing frame 801 is slidably connected to the top of the movable wheel 5. A rectangular groove 802 is provided on one side of the fixing frame 801, and a rubber block 803 is provided on the inner wall of the rectangular groove 802. The rubber block 803 is fixedly connected to the top of the movable wheel 5. When using the fixing device 8, the top of the movable wheel 5 is slid into the interior of the fixing frame 801, thereby squeezing the rubber block 803 into the interior of the rectangular groove 802. This facilitates the movement of the movable wheel 5. Wheel 5 is located at the bottom of support frame 1, facilitating the replacement of different models of movable wheels 5. A notch 804 is provided at the bottom of fixed frame 801, and a locking block 805 is slidably connected to the inner wall of notch 804. One side of the locking block 805 is fixedly connected to the side of the top of the movable wheel 5. By placing the locking block 805 inside the notch 804, the connection between the top of fixed frame 801 and the top of movable wheel 5 becomes tighter. A positioning frame 806 is fitted onto the bottom surface of fixed frame 801, and the positioning frame 806 is positioned within the locking block 805. At the bottom, a rubber plate 809 is fixedly connected to one side of the positioning frame 806. After sliding the locking block 805 to the top of the notch 804, the positioning frame 806 is fitted onto the bottom surface of the fixed frame 801, thus setting the positioning frame 806 at the bottom of the locking block 805. This confines the locking block 805 inside the notch 804. The rubber plate 809 is positioned on the side of the fixed frame 801 away from the positioning frame 806, thus confining the positioning frame 806 to the bottom surface of the fixed frame 801. One side of the fixed frame 801... A damping rod 807 is fixedly connected to the side. The end of the damping rod 807 away from the fixed frame 801 is fixedly connected to one side of the inner wall of the positioning frame 806. A spring 808 is sleeved on the surface of the damping rod 807. One end of the spring 808 is fixedly connected to one side of the fixed frame 801, and the end of the spring 808 away from the fixed frame 801 is fixedly connected to one side of the inner wall of the positioning frame 806. The positioning frame 806 is pulled towards the fixed frame 801 by the spring 808, which makes it easier to restrict the positioning frame 806 to the surface of the fixed frame 801.

[0029] Reference Figure 4The adjusting device 9 includes a rotating rod 901, which is inserted into one side of the top of the support frame 1. A fixing block 902 is fixedly connected to one end of the rotating rod 901, and the fixing block 902 is fixedly connected to one end of the handrail 4. When using the adjusting device 9, the handrail 4 can be rotated easily to adjust the height of its top, thus accommodating operators of different body types. A bolt 904 is threaded through one side of the top of the support frame 1, and a rubber ring 903 is provided at the bottom of the bolt 904. The rubber ring 903 is fixedly connected to the surface of the rotating rod 901. When the rotating rod 901 is rotated to the appropriate position, the bolt 904 is manually rotated, causing the bolt 904 to press against one side of the rubber ring 903. This design facilitates the restriction of the rotating rod 901 to one side of the top of the support frame 1. A semi-circular plate 905 is rotatably fitted onto the bottom of the bolt 904. The semi-circular plate 905 is fitted onto the top of the rubber ring 903, pressing the semi-circular plate 905 against the top of the rubber ring 903. This design facilitates the restriction of the bolt 904 to one side of the rubber ring 903. A threaded rod 907 is threaded through and inserted into one side of the support frame 1. A limiting strip 908 is rotatably fitted onto the top of the threaded rod 907. A positioning rod 906 is fixedly connected to the bottom of the limiting strip 908. The positioning rod 906 is slidably inserted through and inserted into one side of the support frame 1. The threaded rod 907 is manually rotated. Under the restriction of the positioning rod 906, the limiting strip 908 is positioned at the bottom of the handrail 4, thus preventing the handrail 4 from rotating downwards.

[0030] Working principle: When using the rotary tiller, the fuel engine 3 drives the rotating roller to rotate, allowing the rotary teeth 7 on the surface of the rotating roller to effectively loosen the soil. When using the fixing device 8, the top of the moving wheel 5 slides into the inside of the fixing frame 801, thereby squeezing the rubber block 803 into the inside of the rectangular groove 802. The locking block 805 is placed inside the notch 804, and the positioning frame 806 is fitted onto the bottom of the surface of the fixing frame 801. The spring 808 pulls the positioning frame 806 towards the fixing frame 801, thus securing the positioning frame 806 to the surface of the fixing frame 801. The positioning frame 806 is then positioned at the bottom of the locking block 805, thus securing the locking block 805 inside the notch 804. This facilitates the mounting of the moving wheel 5 on the support frame. The bottom of the support frame 1 is designed to facilitate the replacement of different models of casters 5. When using the adjustment device 9, the handrail 4 can be rotated smoothly via the handrail 4. When the rotating rod 901 is rotated to the appropriate position, the bolt 904 is manually controlled to rotate, which causes the bolt 904 to press against one side of the rubber ring 903, thereby pressing the semi-circular plate 905 against the top of the rubber ring 903. This helps to restrict the bolt 904 to one side of the rubber ring 903, and also helps to restrict the rotating rod 901 to one side of the top of the support frame 1. The threaded rod 907 is manually controlled to rotate, and under the restriction of the positioning rod 906, the limiting strip 908 is set at the bottom of the handrail 4. This prevents the handrail 4 from rotating downwards, and makes it easy to adjust the height of the top of the handrail 4, which is convenient for operators of different body types.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
