Description

Technical Field

[0001] The present invention belongs to the technical field of plant cultivation equipment, and specifically relates to a feeding device for forestry seedling raising beds. Background Art

[0002] A seedling raising bed is a special facility used for seed germination, seedling growth, and the entire seedling raising process. Its application scope is extensive, covering multiple fields such as forestry, agriculture, and horticulture. This facility provides a suitable environment for plant growth and is usually equipped with control functions for temperature, humidity, and light to ensure that seeds can germinate smoothly and cultivate healthy seedlings for subsequent transplantation or replanting. Seedlings are usually placed in seedling pots, and the seedling pots are placed on the seedling raising bed. Given that the seedling pots contain soil, they are relatively heavy. In the case of large-scale cultivation, relying on manual handling of seedling pots to the seedling raising bed will be overly burdensome.

[0003] A patent of Chinese Patent Application CN113911713B discloses a feeding device for forestry seedling raising beds. The key points of its technical solution are: including a mounting seat, and further including a main body, a placing mechanism, a cleaning mechanism, a driving mechanism, a conveying mechanism, and a pushing mechanism. The number of mounting seats is four, and the main body is installed above the mounting seats. The conveying mechanism is installed in the main body, and the placing mechanism is installed above the conveying mechanism. One end of the main body is installed with a cleaning mechanism, and the other end of the main body is installed with a conveying mechanism. The conveying mechanism is connected to the main body through the driving mechanism.

[0004] However, the above technology often has the following defects: The above device has the function of transporting seedling pots to the seedling raising bed. However, in actual applications, especially in large-scale seedling raising operations, multi-layer seedling raising beds are usually adopted. The design of such multi-layer seedling raising beds requires feeding seedling pots on each layer. However, the above device is limited to feeding single-layer seedling raising beds, which will bring great limitations in actual use. Since it cannot meet the requirements of multi-layer seedling raising beds, this limits the application scope and efficiency of the device. Summary of the Invention

Specific Embodiments

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Example 1: As Figures 1 to 5 shown, a feeding device for a forestry seedling raising bed according to an embodiment of the present invention includes a base 1 and a group of loading plates 4. A group of universal wheels are provided on the bottom surface of the base 1; the loading plates 4 are connected by brackets. A pair of telescopic frames 2 are fixedly connected to the top surface of the base 1, and the top end of the telescopic frame 2 is fixedly connected to the bottommost loading plate 4; a hydraulic rod 3 is fixedly connected to the inner wall of the base 1 through a bracket, and the output end of the hydraulic rod 3 is used to push the loading plate 4; A electric guide rail 5 is fixedly connected to the side wall of the bottommost loading plate 4, a connecting plate 6 is slidably connected to the electric guide rail 5, and a group of rotating shafts 7 are rotatably connected to the connecting plate 6. One end of the rotating shaft 7 away from the connecting plate 6 is fixedly connected to a pushing plate 8; A plurality of card slots 11 are provided on the side of the connecting plate 6 away from the loading plate 4. A connecting ring 9 is slidably connected to the rotating shaft 7. A round rod 10 that is clamped with the card slot 11 is fixedly connected to the side of the connecting ring 9 close to the connecting plate 6. A fixing ring 12 is fixedly connected to the surface of the rotating shaft 7, and a group of first springs are fixedly connected between the fixing ring 12 and the connecting ring 9. A first positioning plate 13 and a second positioning plate 14 are fixedly connected to the side of the connecting plate 6 close to the connecting ring 9.

[0028] When the seedling tray needs to be transported to the seedling bed in this application, first place the seedling tray on the multi-layer feeding plate 4 for storage. Then move this device to the multi-layer seedling bed side, and then drive the feeding plate 4 to move by means of the electric telescopic rod, so that the topmost feeding plate 4 is aligned with the bottom layer of the seedling bed. Then rotate the rotating shaft 7 except for the one corresponding to the topmost feeding plate 4, so that the pushing plate 8 is placed horizontally. At this time, the connecting plate 6 can be driven to move by means of the electric guide rail 5, so that the connecting plate 6 drives the uppermost pushing plate 8 to push the seedling tray onto the seedling bed. After the feeding of the seedling tray on the topmost feeding plate 4 is completed, the middle feeding plate 4 can be moved to the position where feeding is required on the multi-layer seedling bed again by means of the electric telescopic rod. And so on, let the uppermost and lowermost pushing plates 8 be placed horizontally, and the middle pushing plates 8 be placed vertically. Use the middle pushing plates 8 to continue to push the seedling trays on the feeding plate 4 onto the multi-layer seedling bed. Through the above mechanism, flexible feeding of the multi-layer seedling bed can be carried out, and the feeding plate 4 in this application is also multi-layered, which can store more seedling trays.

[0029] When the rotating shaft 7 in this application needs to be rotated, the connecting ring 9 can be pulled, so that the connecting ring 9 drives the round rod 10 to disengage from the card slot 11. Then the rotating shaft 7 can be rotated, so that the round rod 10 contacts the second positioning plate 14. At this time, the pushing plate 8 will be placed horizontally. At the same time, the round rod 10 will be clamped with the card slot 11 under the action of the first spring pushing the connecting ring 9. When the pushing plate 8 needs to be placed vertically, let the round rod 10 disengage from the card slot 11 again, and then rotate the rotating shaft 7, so that the round rod 10 contacts the first positioning plate 13. At this time, the pushing plate 8 on the rotating shaft 7 will be placed vertically. Through the above mechanism, the pushing plate 8 can be fixed after rotation to facilitate the use of the pushing plate 8.

[0030] A fixing plate 17 is fixedly connected to the side of the connecting plate 6 away from the connecting ring 9. A driving plate 15 is fixedly connected to the surface of the rotating shaft 7. A hollow elastic plate 16 is fixedly connected between the driving plate 15 and the fixing plate 17. An air inflation assembly for inflating the elastic plate 16 is arranged on the lowermost feeding plate 4; when the rotating shaft 7 in this application needs to be rotated, first pull the round rod 10 to disengage from the card slot 11. At this time, the elastic plate 16 can temporarily limit the rotating shaft 7. Then the air inflation assembly can inflate the elastic plate 16 on the corresponding rotating shaft 7 that needs to be rotated. At this time, the elastic plate 16 will expand, thereby pushing the driving plate 15, so that the driving plate 15 drives the rotating shaft 7 to rotate, and then the pushing plate 8 is placed horizontally. At this time, the round rod 10 will enter the card slot 11 under the action of the first spring to fix the rotating shaft 7. When the rotating shaft 7 needs to be reset, move the clamping rod to disengage from the card slot 11 again, and then let the gas in the elastic plate 16 be discharged from the air inflation assembly. At this time, the elastic plate 16 will drive to recover, thereby driving the rotating shaft 7 to reset.

[0031] The inflation assembly includes a support plate 19 fixedly connected to the side wall of the feeding plate 4. A hollow elastic block 20 is fixedly connected to the support plate 19. The connecting plate 6 can squeeze the elastic block 20. A group of connecting pipes 18 communicate with the inside of the elastic block 20. The connecting pipes 18 communicate with the corresponding elastic plates 16 respectively. A control valve is arranged on the connecting pipe 18. In this application, when it is necessary to rotate the uppermost rotating shaft 7, the control valves on the connecting pipes 18 except those communicating with the uppermost elastic plate 16 can be closed. Then, the electric guide rail 5 is used to control the connecting plate 6 to squeeze the elastic block 20, so that the gas in the elastic block 20 enters the elastic plate 16 through the connecting pipe 18, thereby making the elastic plate 16 expand to push the rotating shaft 7 to rotate. Then, after the clamping rod is clamped with the clamping groove 11, the rotating shaft 7 will be limited. After that, when the connecting plate 6 moves away from the elastic block 20, due to the limitation of the rotating shaft 7, the gas in the elastic plate 16 will not flow back to the elastic block 20 through the connecting pipe 18. After the clamping rod disengages from the clamping groove 11, after the elastic block 20 loses the extrusion of the connecting plate 6, the gas in the elastic plate 16 will return to the elastic block 20, so that the elastic block 20 and the elastic plate 16 are reset.

[0032] On the discharging side of the feeding plate 4, a detachable and hollow recycling block 21 is arranged. An inlet groove 22 is opened at the top end of the recycling block 21. A group of inclined bristles 23 are fixedly connected to the inner wall of the inlet groove 22. When the seedling-raising pots are on the feeding plate 4 in this application, it is inevitable that soil will fall on the feeding plate 4. At this time, while the pushing plate 8 pushes the seedling-raising pots, the soil on the feeding plate 4 can also be pushed, so that the soil enters the recycling block 21 through the inlet groove 22 for recycling. At the same time, the bristles 23 can clean the bottom surface of the passing seedling-raising pots, clean the soil at the bottom of the seedling-raising pots, and then enter the recycling block 21 through the inlet groove 22.

[0033] A moving plate 24 made of magnetic material is hermetically and slidably connected to the inner wall of the recycling block 21. A group of second springs are fixedly connected between the bottom surface of the moving plate 24 and the bottom surface of the recycling block 21. A magnetic block 25 magnetically attracted to the moving plate 24 is fixedly connected to the side of the pushing plate 8 close to the recycling block 21. When the pushing plate 8 in this application moves above the recycling block 21, the magnetic block 25 will attract the moving plate 24 to move upward. Then, after the moving plate 24 is reset, the moving plate 24 will be reset under the pulling of the second spring. At this time, the inlet groove 22 will inhale air, so as to inhale the soil around the inlet groove 22 into the recycling block 21 to improve the effect of cleaning the soil. At the same time, when the moving plate 24 is reset, due to the action of the second spring, it will vibrate repeatedly, so that the soil above the moving plate 24 is more evenly distributed on the moving plate 24 under the action of vibration, thereby increasing the recycling volume of the recycling block 21 for the soil.

[0034] A connecting groove 26 is formed in the recycling block 21, an air inlet groove communicating with the connecting groove 26 is formed in the bottom surface of the recycling block 21, a plurality of air outlet holes 27 communicating with the connecting groove 26 are formed in the inner wall of the feeding groove 22, and the positions of the air outlet holes 27 correspond to the bristles 23; when the moving plate 24 in this application moves downward, it will push the gas in the recycling block 21 into the connecting groove 26 from the inlet groove, and then obliquely blow it onto the bristles 23 from the air outlet holes 27, so as to blow the soil on the bristles 23 away, so as to achieve the effect of cleaning the bristles 23.

[0035] Embodiment 2: As Figures 6 to 7 shown, compared with Embodiment 1, another implementation manner of the present invention is: a pair of limiting plates 28 are slidably connected to the inner wall of the feeding plate 4, a group of rollers 29 are fixedly connected to the side of the limiting plate 28 away from the inner wall of the feeding plate 4, and a pushing assembly for pushing the limiting plate 28 is arranged on the feeding plate 4; after the seedling raising pot is placed on the feeding plate 4 in this application, the pushing assembly can be used to push the limiting plate 28, so that the rollers 29 are in contact with the seedling raising pot. At this time, the seedling raising pot will be limited under the action of the thrust, preventing the seedling raising pot from shaking. When the seedlings are pushed onto the feeding plate, the rollers 29 can assist the seedling raising pot to move.

[0036] The pushing assembly includes a rectangular plate 30 fixedly connected to the inner wall of the feeding plate 4, a sliding plate 31 is slidably connected in the rectangular plate 30, the sliding plate 31 is fixedly connected to the limiting plate 28 on the side away from the rectangular plate 30, and a group of third springs are fixedly connected between the side of the sliding plate 31 away from the limiting plate 28 and the inner wall of the rectangular plate 30; in this application, the limiting plate 28 can use the force of the third spring to push the sliding plate 31, so that the limiting plate 28 applies a thrust to the seedling raising pot, thereby limiting the seedling raising pot on the feeding plate 4.

[0037] Working principle: When the seedling tray needs to be transported to the seedling bed in this application, first place the seedling tray on the multi-layer feeding plate 4 for storage. Then move this device to the multi-layer seedling bed side, and then drive the feeding plate 4 to move by means of the electric telescopic rod, so that the topmost feeding plate 4 is aligned with the bottom layer of the seedling bed. Then rotate the rotating shaft 7 except for the one corresponding to the topmost feeding plate 4 to make the pushing plate 8 horizontally placed. At this time, the connecting plate 6 can be driven to move by means of the electric guide rail 5, so that the connecting plate 6 drives the uppermost pushing plate 8 to push the seedling tray onto the seedling bed. After the feeding of the seedling tray on the topmost feeding plate 4 is completed, the middle feeding plate 4 can be moved to the position where feeding is required on the multi-layer seedling bed again by means of the electric telescopic rod. And so on, make the uppermost and lowermost pushing plates 8 horizontally placed and the middle pushing plates 8 vertically placed, and use the middle pushing plates 8 to continue to push the seedling trays on the feeding plate 4 onto the multi-layer seedling bed. Through the above mechanism, flexible feeding of the multi-layer seedling bed can be achieved, and the feeding plate 4 in this application is also multi-layered and can store more seedling trays; when the rotating shaft 7 in this application needs to be rotated, the connecting ring 9 can be pulled to make the connecting ring 9 drive the round rod 10 to disengage from the card slot 11. Then the rotating shaft 7 can be rotated to make the round rod 10 contact the second positioning plate 14. At this time, the pushing plate 8 will be horizontally placed, and at the same time, the round rod 10 will be engaged with the card slot 11 under the action of the first spring pushing the connecting ring 9. When the pushing plate 8 needs to be vertically placed, make the round rod 10 disengage from the card slot 11 again, and then rotate the rotating shaft 7 to make the round rod 10 contact the first positioning plate 13. At this time, the pushing plate 8 on the rotating shaft 7 will be vertically placed. Through the above mechanism, the pushing plate 8 can be fixed after rotation to facilitate the use of the pushing plate 8.

[0038] When the rotating shaft 7 in the present application needs to rotate, first pull the round rod 10 out of the card slot 11. At this time, the elastic plate 16 can temporarily limit the rotating shaft 7. Then, the inflating assembly can inflate the elastic plate 16 on the corresponding rotating shaft 7 that needs to rotate. At this time, the elastic plate 16 will expand, thereby pushing the driving plate 15, causing the driving plate 15 to drive the rotating shaft 7 to rotate, and then making the push plate 8 placed horizontally. At this time, the round rod 10 will enter the card slot 11 under the action of the first spring to fix the rotating shaft 7. When the rotating shaft 7 needs to be reset, move the clamping rod out of the card slot 11 again, and then let the gas in the elastic plate 16 be discharged from the inflating assembly. At this time, the elastic plate 16 will drive the restoration, thereby driving the rotating shaft 7 to reset; in the present application, when the uppermost rotating shaft 7 needs to be rotated, the control valves on the connecting pipes 18 except for those communicating with the uppermost elastic plate 16 can be closed, and then the connecting plate 6 is controlled by the electric guide rail 5 to squeeze the elastic block 20, so that the gas in the elastic block 20 enters the elastic plate 16 from the connecting pipe 18, thereby making the elastic plate 16 expand and push the rotating shaft 7 to rotate. Then, after the clamping rod is clamped with the card slot 11, the rotating shaft 7 will be limited. After that, when the connecting plate 6 moves away from the elastic block 20, due to the limitation of the rotating shaft 7, the gas in the elastic plate 16 will not flow back from the connecting pipe 18 to the elastic block 20. After the clamping rod is disengaged from the card slot 11, after the elastic block 20 loses the extrusion of the connecting plate 6, the gas in the elastic plate 16 will return to the elastic block 20, causing the elastic block 20 and the elastic plate 16 to be reset.

[0039] When the seedling-raising pot in the present application is on the feeding plate 4, it is inevitable that soil will fall on the feeding plate 4. At this time, while the push plate 8 pushes the seedling-raising pot, it can also push the soil on the feeding plate 4, so that the soil enters the recovery block 21 from the feeding groove 22 to be recovered. At the same time, the brush hairs 23 can clean the bottom surface of the passing seedling-raising pot, clean the soil at the bottom of the seedling-raising pot, and then enter the recovery block 21 from the feeding groove 22; when the push plate 8 in the present application moves above the recovery block 21, the magnetic block 25 will attract the moving plate 24 to move upward. Then, after the moving plate 24 is reset, the moving plate 24 will be reset under the pull of the second spring. At this time, the feeding groove 22 will inhale air, thereby inhaling the soil around the feeding groove 22 into the recovery block 21 to improve the effect of cleaning the soil. At the same time, when the moving plate 24 is reset, due to the action of the second spring, it will shake repeatedly, so that the soil above the moving plate 24 will be more evenly distributed on the moving plate 24 under the action of the shaking, thereby increasing the recovery volume of the soil by the recovery block 21; when the moving plate 24 moves downward in the present application, it will push the gas in the recovery block 21 from the inlet groove into the connecting groove 26, and then blow obliquely onto the brush hairs 23 from the air outlet hole 27, thereby blowing off the soil on the brush hairs 23 to achieve the effect of cleaning the brush hairs 23.

Taking the perspective of the person observing as the standard, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
