Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and more specifically, to an automatic feeding device for a rice transplanter seedbed. Background Technology

[0002] A rice transplanter is an agricultural machine that automatically plants rice seedlings into paddy fields. During operation, the mechanical gripper picks up a certain number of rice seedlings from the seedbed on the transplanting platform and plants them into the soil, completing the automatic transplanting. However, traditional ride-on rice transplanters require two operators to work together to complete the transplanting task. One person is responsible for driving the transplanter, and the other is responsible for feeding the seedbed.

[0003] In existing technologies, rice transplanters typically use standardized seedling trays for seedling cultivation, and during transplanting, the trays are manually or semi-automatically transported to the seedling collection position one by one. However, due to the limited seedling storage capacity of the transplanter, frequent stops are required to replenish the seedling trays during continuous operation, leading to reduced work efficiency. Furthermore, manual feeding methods suffer from high labor intensity and poor tray positioning accuracy, resulting in poor operational stability of the seedling collection mechanism.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0041] Embodiment 1:

[0042] Please refer to Figures 1 to 10 A seedling bed automatic feeding device of a seedling inserting machine, comprising a mounting frame 1, the mounting frame 1 is provided with a guide plate 2 and a seedling inserting mechanism 3, the guide plate 2 is provided with a guide groove, and the guide groove is used for providing seedlings for the seedling inserting mechanism 3;

[0043] Among them, the seedling inserting mechanism 3 is prior art, and will not be described again;

[0044] The mounting frame 1 is provided with a gantry 4, rotating rods 5 are uniformly and horizontally installed on the inner side walls of the gantry 4, the rotating rods 5 are uniformly distributed from top to bottom, and support plates 6 are fixedly installed on the side walls of the rotating rods 5;

[0045] The side wall of the gantry 4 is uniformly provided with a plurality of insertion holes corresponding to the support plates 6, the insertion holes are located below the corresponding support plates 6, and an insertion rod 7 is slidably arranged in each insertion hole, so that when the insertion rod 7 is in contact with the bottom wall of the support plate 6, the support plate 6 can be provided with a supporting force to keep the support plate 6 in a horizontal state, the gantry 4 is provided with a driving mechanism for driving the insertion rod 7 to move, and the mounting frame 1 is provided with a displacement mechanism for moving the support plate 6 to a specified position; the gantry 4 is provided with a limiting block 37 matched with the support plate 6; the limiting block 37 is located below the insertion rod 7, so that when the support plate 6 rotates, the support plate 6 is limited by the limiting block 37, preventing the upper support plate 6 from contacting the lower support plate 6 during rotation, and an extension plate 38 made of elastic material is fixedly arranged at the end of the support plate 6 away from the rotating rod 5, so that the extension plate 38 can ensure that the seedlings on the surface of the support plate 6 can move to the surface of the guide plate 2 during rotation of the support plate 6, and the extension plate 38 is made of elastic material, so that when the extension plate 38 moves and is blocked by the guide plate 2, the extension plate 38 can deform, thereby ensuring the normal movement of the gantry 4.

[0046] The gantry 4 is provided with a cavity 8, and the side wall of the cavity 8 close to the side of the support plate 6 is uniformly provided with a plurality of holes 9 communicating with the outside, and the mounting frame 1 is provided with a liquid supply mechanism for supplying water to the cavity 8.

[0047] During operation, when the seedlings on the surface of the guide plate 2 are consumed, the gantry 4 is moved by the displacement mechanism, so that the support plate 6 with seedlings on the surface is moved to the surface of the guide plate 2, and then the insertion rod 7 below the support plate 6 is driven out of the gantry 4 by the driving mechanism.

[0048] Since the support plate 6 is arranged on the side wall of the rotating rod 5, that is, the rotating rod 5 is located at one end of the support plate 6, when the insertion rod 7 is separated from the support plate 6, the support plate 6 will drive the rotating rod 5 to rotate under the action of gravity until the top wall of the support plate 6 is attached to the top wall of the guide plate 2, at this time the support plate 6 is parallel to the guide plate 2, and under the action of the liquid supply mechanism, the water in the cavity 8 is discharged through the holes 9, and the water discharged from the holes 9 flows to the surface of the support plate 6, thereby reducing the friction between the seedlings connected in blocks on the surface of the support plate 6 and the support plate 6, so that the seedlings connected in blocks on the surface of the support plate 6 can slide along the surface of the support plate 6 to the guide groove on the surface of the guide plate 2, thereby realizing the function of automatically supplying the guide groove.

[0049] During the process of supplying the guide groove, only one person is needed to complete the operation, which reduces the operation process and improves the work efficiency.

[0050] As Figure 4 , Figure 5As shown, the driving mechanism includes a mounting groove 10 opened on the top wall of the insertion hole, and an elastic member 11 is mounted between the side wall of the mounting groove 10 and the insertion rod 7. When the insertion rod 7 is not subjected to external force, the elastic member 11 is in a natural state. At this time, the end face of the insertion rod 7 close to one end of the support plate 6 is retracted into the insertion hole, and the end of the insertion rod 7 away from the support plate 6 is located outside the gantry 4. A threaded rod 12 is vertically rotatably mounted on the side wall of the gantry 4, and a first sliding block 13 is threadedly mounted on the threaded rod 12.

[0051] A motor 14 and a limiting rod 15 are fixedly mounted on the gantry 4. The output end of the motor 14 is connected with the rotating shaft of the threaded rod 12. The first sliding block 13 is movably sleeved on the limiting rod 15. The first sliding block 13 is limited from rotating by the limiting rod 15, so that the first sliding block 13 can only move up and down along the threaded rod 12. Therefore, in the process of rotating the threaded rod 12 by the motor 14, the first sliding block 13 can move up and down. A baffle 16 cooperating with the insertion rod 7 is fixedly mounted on the side wall of the first sliding block 13, and the baffle 16 moves up and down together with the first sliding block 13.

[0052] When it is needed to place the seedlings on the surface of the support plate 6, first, the support plate 6 is rotated to be in a horizontal state, and then the insertion rod 7 is manually pushed to pass through the insertion hole and move to below the corresponding support plate 6. At this time, the elastic member 11 is in a stretched state.

[0053] Then, the motor 14 is started to drive the first sliding block 13 and the baffle 16 to move upward through the rotating threaded rod 12, so that the baffle 16 gradually moves to the end face of the insertion rod 7 which has been inserted below the corresponding support plate 6.

[0054] At this time, under the cooperation of the baffle 16 and the elastic member 11, the insertion rod 7 can be fixed below the support plate 6, so that the support plate 6 can be kept in a horizontal state.

[0055] As shown in Figure 1 , Figure 7 The displacement mechanism includes a guide rod 17 vertically fixedly mounted on the mounting frame 1, and a second sliding block 18 is slidably sleeved on the guide rod 17. The gantry 4 is connected with the second sliding block 18. The position of the gantry 4 can be limited by the guide rod 17 and the second sliding block 18 to prevent the gantry 4 from deviating, so as to ensure that the seedlings on the surface of the support plate 6 can enter the guide groove;

[0056] A horizontal plate 19 is fixedly mounted on the bottom wall of the gantry 4. An electric telescopic rod 20 with an upward output end is vertically fixedly mounted on the mounting frame 1. The output end of the electric telescopic rod 20 is in contact with the horizontal plate 19. The electric telescopic rod 20 is used to push the horizontal plate 19 to move upward. The height of the gantry 4 can be adjusted by controlling the extension amount of the output end of the electric telescopic rod 20. The specified length of the output end of the electric telescopic rod 20 is prior art, and will not be described here.

[0057] Under the action of gravity, the gantry 4 has a tendency to drive the second sliding block 18 to slide along the guide rod 17 downward, so that the horizontal plate 19 is attached to the output end of the electric telescopic rod 20, and when the output end of the electric telescopic rod 20 is stretched or contracted, the gantry 4 will move upward or downward, thereby changing the position of the gantry 4.

[0058] As shown in Figure 3 , Figure 4 , the liquid supply mechanism includes a guide pipe 21 fixedly inserted on the top wall of the horizontal plate 19, the bottom end of the guide pipe 21 penetrates through the horizontal plate 19, and the top end of the guide pipe 21 extends into the cavity 8;

[0059] A water storage groove 22 is formed on the top wall of the mounting frame 1, because there is water in the rice field when the seedlings are transplanted, and the mounting frame 1 will sink into the rice field mud, at this time, the water in the rice field will spread to the surface of the top wall of the mounting frame 1 and enter the water storage groove 22, the output end of the electric telescopic rod 20 is fixedly installed with a water inlet pipe 23, the bottom end of the water inlet pipe 23 extends into the water storage groove 22, and the top end of the water inlet pipe 23 is located directly below the guide pipe 21, so when the output end of the electric telescopic rod 20 is in contact with the horizontal plate 19, the guide pipe 21 is in communication with the water inlet pipe 23.

[0060] The guide rod 17 is externally sleeved with a bellows 24, the two ends of the bellows 24 are fixedly connected with the second sliding block 18 and the mounting frame 1 respectively, when the output end of the electric telescopic rod 20 drives the second sliding block 18 to move upward, the bellows 24 is stretched, at this time, the bellows 24 is in a negative pressure state; when the second sliding block 18 moves downward, the bellows 24 is extruded, at this time, the bellows 24 is in a high pressure state; the side wall of the bellows 24 is fixedly inserted with an air pipe 39 extending into the water inlet pipe 23.

[0061] The bottom end and the top end of the water inlet pipe 23 are fixedly installed with a water inlet valve 25 and a drain valve 26 respectively, and the ratio of the inner diameter of the bellows 24 to the inner diameter of the water inlet pipe 23 is 10:1, so the volume of the stretched bellows 24 is greater than the volume of the water inlet pipe 23.

[0062] When the bellows 24 is in a negative pressure state, under the communication action of the air pipe 39, at this time, the bellows 24 sucks water from the water storage groove 22 through the air pipe 39 and the water inlet valve 25; when the bellows 24 is in a high pressure state, the water in the bellows 24 is extruded and discharged into the water inlet pipe 23 through the drain valve 26, when the water inlet pipe 23 is filled with water, the water in the water inlet pipe 23 is discharged through the drain valve 26, the water flowing out of the drain valve 26 flows along the guide pipe 21 into the cavity 8, thereby playing a role of supplying water for the cavity 8.

[0063] As shown in Figure 6 , the inner wall of the hole 9 is fixedly installed with a first elastic rope 27, and the first elastic rope 27 is fixedly installed with a spoiler 28.

[0064] In the process of drainage of the hole 9, the water flow impacts the spoiler block 28, the spoiler block 28 is separated from the hole 9, at this time, under the action of the first elastic rope 27, the spoiler block 28 shakes, thereby changing the diffusion area of the water discharged from the hole 9, increasing the contact area of the water flow with the seedling on the surface of the supporting plate 6, the water falling on the surface of the seedling gradually flows to the surface of the supporting plate 6, improving the lubricating effect, and playing a role in ensuring that the seedling can slide at a uniform speed along the surface of the supporting plate 6.

[0065] As shown in Figure 2 The second elastic rope 29 is fixedly installed between the inner side walls of the opposite sides of the water storage tank 22, a spherical filter barrel 30 is fixedly installed on the second elastic rope 29, the ratio of the height of the water storage tank 22 to the diameter of the filter barrel 30 is 2:1, the bottom end of the water inlet pipe 23 is inserted into the inside of the filter barrel 30, and the water inlet pipe 23 is fixedly connected with the filter barrel 30.

[0066] When the water inlet pipe 23 absorbs water, under the action of the filter barrel 30, impurities in the water can be filtered, preventing the water inlet pipe 23 from being blocked, playing a role in enabling the water inlet pipe 23 to normally absorb water, and in the process of movement of the rice transplanter, under the joint action of inertia and the second elastic rope 29, the filter barrel 30 shakes, thereby being able to shake off impurities adhering to the surface of the filter barrel 30, ensuring that the filter barrel 30 can normally work.

[0067] As shown in Figure 9 A sliding groove is formed in the side wall of the second sliding block 18, the top end of the sliding groove penetrates through the top wall of the second sliding block 18, a guide block 31 that slidably cooperates with the second sliding block 18 is fixedly installed on the outer wall of the gantry 4, the guide block 31 on the side wall of the gantry 4 is aligned with the sliding groove, the guide block 31 is inserted into the sliding groove, the gantry 4 and the second sliding block 18 are connected together, thereby enabling the gantry 4 to move up and down through the second sliding block 18; and the guide block 31 is rectangular, because the rectangular guide block 31 is arranged in the sliding groove and can only move up and down along the sliding groove, the gantry 4 can be prevented from shaking, and the stability of the gantry 4 is improved.

[0068] Under the cooperation of the guide block 31 and the sliding groove, the gantry 4 can be quickly replaced. After all the seedlings in the gantry 4 being used are transferred to the guide groove, the operator can immediately replace the gantry 4 full of seedlings prepared in advance, thereby improving the continuity and work efficiency of the rice transplanting operation.

[0069] As shown in Figure 4 It also includes a remote controller 32 and a switch 33, the gantry 4 is provided with a storage battery 34, a wireless receiving module 35 and a control module 36;

[0070] The switch 33 is used to control the work of the electric telescopic rod 20, and the switch 33 is connected in series with the electric telescopic rod 20;

[0071] The remote controller 32 is used to send signals to the wireless receiving module 35;

[0072] The wireless receiving module 35 sends the received signals to the control module 36;

[0073] The control module 36 is used to control the operation of the motor 14;

[0074] The battery 34 is used to supply power to the motor 14, the wireless receiving module 35 and the control module 36.

[0075] The wireless receiving module 35 receives signals sent by the remote controller 32, which is a prior art and will not be described in detail.

[0076] Therefore, during the operation, the driver of the rice transplanter can conveniently complete the feeding during the driving.

[0077] The above description is only the preferred embodiment of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
