Description

Technical Field

[0002] Rice is a core grain crop in my country, accounting for 27% of the country's total grain planting area and 34% of its total output. It is of strategic significance to ensuring national food security. In mechanized rice production, rice seedling cultivation is key to integrating agricultural machinery and agronomy. Trayless rice seedling cultivation, which eliminates the cost of seedling trays and simplifies the operation process, has become a key direction for simplified cultivation.

[0003] Existing discless seedling cutting machines are mainly divided into two categories. One is a manually pushed cutting machine, which relies on manpower to push the frame to move, and the engine drives the cutting knife on the wheel axle to operate. Its advantage is its simple structure, but it has the core defects of high labor intensity and low cutting accuracy, which causes serious damage to the seedlings. The second is a rail-type electric cutting machine, which uses a slide rail structure to control the moving path (such as the double-layer guide system of the first slide rail and the second slide rail), and drives the cutting knife to move horizontally through a servo motor. Although the problem of path deflection has been solved, the structure is complex, the cost is high, and the slide rails need to be fixed and installed in advance, which has poor flexibility and is time-consuming and labor-intensive to switch between seedling sheds.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1-4 The present invention provides an intelligent discless seedling cutting machine, comprising:

[0034] A chassis 1 is fixedly connected to a front bracket 2, a travel mechanism is installed on the chassis 1, a steering mechanism and a main controller 3 are installed on the front bracket 2, and the main controller 3 has a Beidou navigation agricultural machinery automatic unmanned driving system, an automatic cutting system, and a seedling block cutting length control system;

[0035] The cross-cutting assembly includes a lifting mechanism, a transverse movement mechanism and a first disc cutter 4. The lifting mechanism is fixedly connected to the base frame 1, and the transverse movement mechanism is arranged on the lifting mechanism. The transverse movement mechanism is provided with a first motor 5 and a support mechanism. The first motor 5 is transmission-connected to the first disc cutter 4. The lifting mechanism, the transverse movement mechanism and the first motor 5 are electrically connected to the main controller 3.

[0036] The longitudinal cutting assembly includes a rear bracket 6, several second motors 7 and several second disc cutters 8. A push-pull mechanism is provided on the base frame 1. The rear bracket 6 is provided on the push-pull mechanism. The second motor 7 is provided on the rear bracket 6. The second disc cutters 8 are rotatably connected to the rear bracket 6. The second motor 7 is transmission-connected to the second disc cutters 8. The push-pull mechanism and the second motor 7 are electrically connected to the main controller 3.

[0037] In this device, the main controller 3 is used to control the device, the travel mechanism enables the device to move independently, and the steering mechanism enables the device to realize the steering function, thereby facilitating the adjustment of the cutting direction. The travel mechanism and the steering mechanism are both electrically connected to the main controller 3; the lifting mechanism enables the transverse movement mechanism to be raised or lowered, and can also realize the adjustment of the cutting depth. The transverse movement mechanism causes the first motor 5 and the first disc cutter 4 to move laterally, and the first motor 5 drives the first disc cutter 4 to rotate to realize transverse cutting of the seedlings; the rear bracket 6 is used to install the second disc cutter 8, and the push-pull mechanism is used to control the lifting or pressing of the rear bracket 6, so as to adjust the cutting depth. The second motor 7 drives the second disc cutter 8 to rotate, and the seedlings can be cut longitudinally during the movement of this device.

[0038] During the working process of this device, the main controller 3 is used to start the travel mechanism, which enables the device to move forward, and the steering mechanism enables the device to adjust the travel direction. When cutting begins, the lifting mechanism moves the transverse mechanism downward, so that the first disc cutter 4 cuts into the seedlings. The transverse mechanism operates to make the first motor 5 and the first disc cutter 4 move transversely. At the same time, the first motor 5 drives the first disc cutter 4 to rotate. The rotation speed of the first disc cutter 4 follows the movement speed of the transverse mechanism to achieve transverse cutting of the seedlings. After the transverse cutting of the seedlings at the current position is completed, The lifting mechanism lifts, causing the first disc cutter 4 to leave the seedlings. The device then moves forward and performs a horizontal cut on the next seedling. As the device moves forward, the second disc cutter 8 simultaneously performs a longitudinal cut. The specific process is as follows: the push-pull mechanism pushes the rear bracket 6 downward, causing the second disc cutter 8 to cut into the seedlings. As the device advances, the second motor 7 also drives the second disc cutter 8 to rotate, cutting the seedlings longitudinally. The first and second disc cutters achieve both horizontal and vertical cuts on the seedlings, dividing them into rectangular blocks. The Beidou navigation agricultural machinery automatic unmanned driving system, automatic cutting system, and seedling block cutting length control system enable the device to automatically move forward and backward, adjust direction, and control travel speed, as well as control the horizontal and vertical cuts and cutting length of the seedlings.

The protective shell 14 plays a certain protective role on the first motor 5, and the main controller 3 can control the fourth motor 17.

[0050] The fifth motor 28 drives the second screw 29 to rotate. When the second screw 29 rotates, the support plate 26 moves up and down. The support plate 26 is an inverted L-shaped plate. Figure 1 As shown, the support plate 26 drives the support wheel 27 to rise or fall, and the support wheel 27 contacts the seedlings later than the first disc cutter 4. The support wheel 27 is mainly used to adjust the depth of the first disc cutter 4 cutting into the seedlings. When the lifting plate 11 is at the same height, the support wheel 27 is raised, and the first disc cutter 4 cuts deeper into the seedlings. The support wheel 27 is lowered, and the first disc cutter 4 cuts shallower into the seedlings.

[0051] A further optimized solution is that the push-pull mechanism includes two electric telescopic rods 30 and two connecting plates 31. Several first fixed plates 32 and several second fixed plates 33 are fixedly connected to the base frame 1. The fixed end of the electric telescopic rod 30 is rotatably connected to the first fixed plate 32. The connecting plate 31 is a bent plate with an angle.

[0052] The electric telescopic rod 30 is extended or retracted, driving the connecting plate 31 to rotate. The shape of the connecting plate 31 is shown in the figure, with an angle. When the seedlings need to be cut longitudinally, the electric telescopic rod 30 is extended and the connecting plate 31 is rotated to press the rear bracket 6 downward, so that the second disc cutter 8 cuts into the seedlings.

When the travel direction needs to be adjusted, the main controller 3 controls the steering control mechanism to control the rotation direction of the steering front wheel 41. When the cutting operation starts, the electric telescopic rod 30 is extended and the connecting plate 31 is rotated to press the rear bracket 6 downward, so that the second disc cutter 8 cuts into the seedlings. When the device moves forward, the longitudinal cutting of the seedlings can be realized; the travel step is set on the main controller 3. When the travel step is set, the transverse movement starts.
