Description

Technical Field

[0001] The utility model belongs to the technical field of farmland grooving and ridging, and more specifically, particularly relates to a field ridging grooving device for agricultural machinery. Background Art

[0002] Field ridging and grooving has multiple significances in agricultural production, including improving farmland drainage and irrigation conditions, optimizing crop growth environment, increasing crop yield and quality, saving water resources, and adapting to mechanized operations, etc. There are various field ridging and grooving devices, among which the ridging and grooving machine mounted behind agricultural machinery such as tractors is one of the most commonly used devices. The existing ridging and grooving machines generally consist of upper and lower brackets, connectors connected to agricultural machinery, and multiple grooving knives.

[0003] The existing application number: CN200720085182.2, a double - row ridging plow, which is composed of a traction frame (1), a left turning plow (2), a right turning plow (3) and a double - turning plow (4). The left turning plow (2) is installed on the right side of the traction frame, the right turning plow (3) is installed on the left side of the traction frame, and the double - turning plow (4) is installed in the middle of the traction frame (1). The left turning plow (2), the right turning plow 3 and the double - turning plow (4) are arranged in a horizontal row on the traction frame (1). The advantages of the utility model are: hanging the utility model on a tractor with more than 40 horsepower can quickly ridge the sweet potato field, saving labor, time and effort, with good ridging quality and low production cost.

[0004] Based on the above, most of the multiple grooving knives of the ridging and grooving machine are connected to the lower part of the lower bracket through fixing bolts. To meet the operation requirements of different crops or soils, the spacing between multiple grooving knives often needs to be adjusted. During operation, the staff needs to loosen the bolts one by one, and then re - align and fix the grooving knives on a limited number of screw holes according to the requirements. This process is not only time - consuming and laborious, but also due to the limitation of the distribution of screw holes, the adjustment of the spacing is often difficult to be accurate and error - free, and it is difficult to meet the requirements of precision agriculture operations. Summary of the Utility Model

When the right adjusting grooving tool 5 moves to the left, it will drive the left adjusting grooving tool 5 to move synchronously to the right, reducing the distance between the two adjusting grooving tools 5 and the fixed grooving tool 4, so that the distance between the two adjusting grooving tools 5 and the fixed grooving tool 4 can be adjusted quickly and accurately.

[0068] Embodiment 2:

[0069] On the basis of Embodiment 1, as shown in Appendix Figure 1 to Appendix Figure 7 shown, it further includes an anti-loss component, and the anti-loss component is arranged inside the fixed box 10.

[0070] Among them, the anti-loss component includes:

[0071] The sliding bolt 12 is slidably connected inside the fixed box 10;

[0072] The connecting rod 1201 is fixedly connected behind the sliding bolt 12, and the connecting rod 1201 is slidably connected to the fixed box 10. The function is that when the connecting rod 1201 is pulled to the right, it can drive the sliding bolt 12 to move synchronously to the right, exposing the internal space of the connecting piece 101, which is convenient for connecting with agricultural machinery such as tractors.

[0073] Among them, the anti-loss component further includes:

[0074] The clamping piece 1301 is slidably connected to the bottom right end of the sliding bolt 12;

[0075] Connecting springs 13 are provided in two pieces. The lower ends of the two connecting springs 13 are dispersedly and fixedly connected to the upper surface of the clamping piece 1301, and the upper ends of the two connecting springs 13 are dispersedly and fixedly connected to the bottom of the right end of the sliding bolt 12;

[0076] The clamping groove 11 is formed inside the fixed box 10. Its function is that after the sliding bolt 12 moves to the right in place, under the action of the connecting spring 13, the clamping piece 1301 moves downward and inserts into the clamping groove 11, thereby locking the sliding bolt 12 in the current position, facilitating other operations.

[0077] Among them, the anti-loss component further includes:

[0078] The toggle lever 14 is slidably connected inside the clamping groove 11;

[0079] The return spring 15 has its left end fixedly connected to the right side of the sliding bolt 12, and its right end fixedly connected to the inside of the fixed box 10. Its function is that when the toggle lever 14 is moved upward, the clamping piece 1301 that moves downward and contacts the toggle lever 14 can be moved upward. When the bottom of the clamping piece 1301 disengages from the clamping groove 11, the return spring 15 rebounds, driving the sliding bolt 12 to move leftward until it fits against the blocking piece 1001 again. At this time, the cylindrical part of the sliding bolt 12 is inserted into the connecting member 101.

[0080] The specific usage method and function of this embodiment:

[0081] When it is necessary to connect or disconnect from agricultural machinery through the connecting member 101 and the sliding bolt 12, pulling the connecting rod 1201 to the right can drive the sliding bolt 12 to move synchronously to the right. After the sliding bolt 12 moves to the right in place, under the action of the connecting spring 13, the clamping piece 1301 moves downward and inserts into the clamping groove 11, thereby locking the sliding bolt 12 in the current position, and the internal space of the connecting member 101 is exposed, facilitating the operation of connection or disconnection; after the operation is completed, moving the toggle lever 14 upward can make the clamping piece 1301 move upward. When the bottom of the clamping piece 1301 disengages from the clamping groove 11, the return spring 15 rebounds, driving the sliding bolt 12 to move leftward until it fits against the blocking piece 1001 again. At this time, the cylindrical part of the sliding bolt 12 is inserted into the connecting member 101. This not only makes the operation simple and convenient, avoids the loss of the sliding bolt 12, but also the return spring 15 always presses against the sliding bolt 12, reducing the probability that the sliding bolt 12 disengages from the inside of the connecting member 101 due to the movement of the machine during the operation of grooving the ridge.
