The working principle is as follows: when the device is used, firstly, power is supplied to a driving structure connected with the servo motor 2 and the conveyor belt 14, water is supplied to the telescopic hose 53 through an external water tank and a water pump, when the device is used, firstly, harvested fresh forage grass is placed on the conveyor belt 14 in figure 1, the conveyor belt 14 conveys the forage grass to a position below the cutter 5, when the forage grass moves to the position right below the

cutter

5, 2 servo motors 2 in figure 1 are started, 2 servo motors 2 rotate inwards at the same time, the rotating directions of the 2 servo motors 2 are opposite, the driving gear 3 arranged on the servo motor 2 stably drives the cutter 5 to move downwards in the vertical direction through the working window 4 by utilizing a meshing connection relationship, the functional block 52 moves downwards along with the cutter 5 and contacts with the ratchet 62 in figure 3 to push the ratchet 62 to rotate, and at the moment, the pawl 63 can smoothly slide through the edge of the dentate structure on the ratchet 62, the cutter 5 smoothly continues to move downwards and starts to cut the forage grass on the discharging plate 10 above the fixed shaft 11;

since the servo motor 2 can be precisely controlled, when the knife 5 moves downwards to cut the grass and does not contact with the upper end surface of the discharging plate 10, 2 servo motors 2 stop rotating immediately and rotate in the opposite direction to the previous direction, the servo motors 2 and the control structure thereof are well known in the art and will not be described in detail, so that the servo motors 2 drive the knife 5 to move upwards to separate from the grass through the driving gear 3, the functional block 52 moves upwards along with the knife 5 and contacts with the ratchet 62 from bottom to top, since the ratchet 62 is blocked by the pawl 63, the ratchet 62 cannot rotate, the functional block 52 cannot pass through the ratchet 62, and the 2 functional blocks 52 on both sides lift the vertical plate 6 and the connected structure upwards through the ratchet 62 and move upwards synchronously with the knife 5, at this time, the vertical plate 6 compresses the top spring 61, and the horizontal bar 55 is driven to move upwards, the initial state of the horizontal bar 55 is as shown in fig. 1 and fig. 5, the arc-shaped groove on the horizontal bar 55 extrudes the telescopic hose 53 fixed on the base plate 54, the telescopic hose 53 is pressed by matching with the base plate 54, so that water provided by the external water tank and the water pump can not flow into the internal water tank 51 through the telescopic hose 53 in a large amount, a small amount of water can flow out from the bottom end of the internal water tank 51, the sharp part at the bottom of the cutter 5 is kept clean, liquid medicine or nutrient solution can be added into the water in the external water tank, so that the water flowing out from the bottom end of the internal water tank 51 falls on the grass which is fed to cattle and sheep after cutting is finished, disease control and nutrient supplement are facilitated, and when the horizontal bar 55 moves upwards and the telescopic hose 53 is separated, a large amount of water in the telescopic hose 53 can be discharged, so that the water flowing out from the bottom end of the internal water tank 51 becomes more, and the water brushes the bottom end of the cutter 5, the pasture left after adhesion is washed off, so that the following pasture can be discharged conveniently;

meanwhile, the vertical plate 6 drives the lower plate 7 to move upwards together, the lower plate 7 drives the outer gear 8 to rotate stably through a meshing connection relation, the outer gear 8 drives the storage barrel 82 in fig. 2 to rotate through the mounting shaft 81 to wind the pulling rope 85, the pulling rope 85 pulls the discharging plate 10 to rotate downwards by a certain angle by taking the fixed shaft 11 as an axial direction, so that the discharging plate 10 is integrally inclined and stretches the reset spring 12, the bottom end of the discharging plate 10 is aligned with the collecting tank 13, cut grass falls in the collecting tank 13 along the inclined discharging plate 10 under the lubricating action of the previously falling water, the grass falling in the collecting tank 13 is soaked in the water containing liquid medicine or nutrient solution which also falls along the discharging plate 10, certain water is attached to the surface of the grass, a part of the grass can be absorbed, and the effects of disease control and nutrient supplement are enhanced;

when the vertical plate 6 with the ratchet wheel 62 and the pawl 63 ascends to the vicinity of the magnet 15, the magnet 15 generates strong attraction to the ferrous pawl 63 because the magnet 15 is a neodymium magnet, the pawl 63 is separated from the ratchet wheel 62 and attracted to the magnet 15, so that the ratchet wheel 62 can rotate freely, the functional block 52 can not lift the vertical plate 6 and the connected structure through the ratchet wheel 62, the vertical plate 6 and the connected structure fall and return under the action of the self-gravity and the top spring 61, and the pawl 63 falls and separates from the magnet 15 because the self-gravity of the vertical plate 6 and the connected structure and the action force of the top spring 61 are added together to be far greater than the attraction of the magnet 15 to the pawl 63, so that the pawl 63 falls and returns under the action of the torsion spring because the structure of the pawl 63 is as shown in fig. 6, torsion springs are arranged on both sides of the pawl 63, and when the pawl 63 is separated from the magnet 15, the horizontal bar 55 also falls and resets along with the vertical plate 6, the telescopic hose 53 is extruded again, the telescopic hose 53 is restored to the initial state, a large amount of water cannot flow into the inner water tank 51 from the telescopic hose 53, and at the moment, the bottom end of the cutter 5 is washed and tightened, and a small amount of water still falls on the forage grass below;

and because the lower plate 7 moves downwards along with the vertical plate 6 to reset, the lower plate 7 drives the outer gear 8 to move reversely, the storage cylinder 82 also performs accelerated reverse rotation under the coordination of the inner spring 84 which is actually a torsion spring, the pull rope 85 is not pulled, the pull rope 85 does not pull the discharge plate 10, the discharge plate 10 rotates upwards by taking the fixed shaft 11 as the axial direction under the action of the 2 reset springs 12 at the two sides of the top end of the discharge plate to reset to the horizontal state, and the cutter 5 moves downwards to continue the operation of cutting the pasture;

when the discharge plate 10 is reset, the servo motor 2 stops rotating again and immediately reverses direction, the cutter 5 is driven again by the drive gear 3 to move down to start the grass cutting operation, and then the operation of the relevant parts of the device is as described above, and the device starts to perform the continuous grass cutting discharge operation.
