Description

Technical Field

[0001] The invention relates to the technical field of planting and fertilization, in particular to a fertilization device for poplar cultivation. Background Art

[0002] Poplars are widely cultivated due to their rapid growth and strong adaptability. At the same time, poplars are important afforestation species and industrial timber species, playing an important role in afforestation and timber production in plain areas. Poplar cultivation requires selection of seedlings with well-developed root systems, straight stems, and no mechanical damage and pests and diseases. Poplars are suitable for growing in deep, fertile, loose, and well-drained soil. The planting density is determined according to the variety of poplars, the purpose of cultivation, and the conditions of the afforestation site. For cultivating large-diameter timber, the planting density can be relatively small, generally 4×5 meters. For cultivating small-diameter timber or for use in shelterbelts, the planting density can be appropriately increased, such as 3×3 meters.

[0003] During the cultivation of poplars, fertilizers need to be applied at different growth stages. For middle-aged and young forests, the fertilization method used is to dig trenches around the poplar plants for fertilizer application. The trenches are 15-20 cm deep and covered with soil after fertilization. This can concentrate the fertilizer within the absorption range of the poplar roots and improve fertilizer utilization. In some small-scale plantations, manual fertilization is still used. Since manual fertilization requires carrying solid fertilizers, a large handful of fertilizers will be taken out during sowing, and solid fertilizers will be spread at will, which will result in uneven sowing. At the same time, areas where solid fertilizers are not spread in place need to be sown again, resulting in increased fertilizer usage and reduced fertilization efficiency. Summary of the invention

Then, the contact and separation process between the guide base and the opening and closing plate can be used to control the opening and closing action of the discharge channel of the discharge hole, so that the solid fertilizer inside the storage box can fall normally, fall on the surface of the opening and closing plate, and then roll into the groove synchronously, which not only increases the spreading range of the solid fertilizer, but also disperses the solid fertilizer for the second time when it falls on the surface of the opening and closing plate, making the solid fertilizer spread more evenly. By utilizing the discharge interval period caused by each opening and closing action of the discharge hole, only a small amount of solid fertilizer is discharged each time, so as to avoid excessive use of solid fertilizer and improve the fertilization efficiency.

[0017] 2. By setting up an auxiliary mixing mechanism, the rotating ring rotates synchronously with the mixing blades. When a variety of solid fertilizers are added into the storage box, it can play a stirring role, so that the various solid fertilizers can be mixed evenly while the storage box is moving above the groove. Compared with manual mixing, it saves the user's physical strength and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] See also Figure 1-Figure 9As shown, the purpose of this embodiment is to provide a fertilization device for poplar cultivation, including a storage box 1, four walking wheels are installed at the bottom of the storage box 1, a transmission assembly 6 is arranged between the walking wheel and the outer wall of the storage box 1, a rotating shaft 2 is rotatably connected to the inner wall of one side of the top of the storage box 1, the transmission assembly 6 is fixedly connected to the end of the rotating shaft 2, and the rotating shaft 2 is rotated synchronously with the walking wheel, and the rotating shaft 2 is fixedly connected to the end located inside the storage box 1. A rotating block 21 is fixedly connected to the outer wall of the rotating block 21 on the side away from the rotation center of the rotating shaft 2, and a connecting rod 31 is hinged on the end of the connecting rod 31 away from the rotating block 21. A vertical rod 32 is hinged on the bottom of the vertical rod 32, and an auxiliary sowing mechanism 4 is fixedly connected to the bottom of the vertical rod 32. The auxiliary sowing mechanism 4 is located in the storage box 1, an auxiliary mixing mechanism 7 is also arranged inside the storage box 1 and below the rotating shaft 2. The auxiliary spreading mechanism 4 is used to evenly spread solid fertilizer into the strip grooves and intermittently control the spreading amount of solid fertilizer. The auxiliary mixing mechanism 7 is used to mix and stir the various solid fertilizers added into the storage box 1. A feed hopper 11 is fixedly connected to the top of the storage box 1. The feed hopper 11 is communicated with the inside of the storage box 1. A push rod 12 is fixedly connected to the outer wall of one end of the storage box 1 away from the feed hopper 11. Before fertilizing, the user prepares the solid fertilizer feed hopper 11 for a single fertilization amount, and adds the solid fertilizer into the storage box 1 through the feed hopper 11, and then holds the push rod 12 to push the storage box 1 to move above the strip groove in cooperation with the walking wheels. A support rod 33 is fixedly connected to the inner wall of the bottom of the storage box 1, and the bottom end of the vertical rod 32 is arranged to slide through the inner wall of the support rod 33, and a dredging blade 34 is fixedly connected to the outer wall of the bottom end of the vertical rod 32. The transmission assembly 6 includes a first pulley 61 fixedly connected to the outer wall of the walking wheel, and a second pulley 62 is fixedly connected to the end of the rotating shaft 2 away from the rotating block 21, and a belt 63 is connected for transmission between the first pulley 61 and the second pulley 62. With the rotation of the walking wheel, the first pulley 61 rotates synchronously, and the second pulley 62 rotates synchronously with the rotating shaft 2 by the transmission effect of the belt 63. The rotating block 21 rotates with the rotating shaft 2, so that the rotating block 21 makes a circular motion with the connecting rod 31. Since the hinge point between the connecting rod 31 and the rotating block 21 is in an eccentric position, and the vertical rod 32 is slidably matched with the support rod 33, the support rod 33 can limit the vertical rod 32 during the up and down movement to ensure the stable operation of the vertical rod 32, so that when the connecting rod 31 rotates to a high position with the rotating block 21, the vertical rod 32 will When the connecting rod 31 is raised, and the rotating block 21 rotates to a lower position with the rotating block 21, the vertical rod 32 descends in height inside the storage box 1. At the same time, the vertical rod 32 will carry the dredging blade 34 to reciprocate during the rising and falling period, and the dredging blade 34 is located in the channel connecting the bottom of the storage box 1 and the lower bin 41, thereby achieving the purpose of dredging. When solid fertilizers fall in the channel at the same time, blockage is likely to occur, and the dredging blade 34 moves up and down to push the blocked solid fertilizer, making the inside of the solid fertilizer unstable, so that it can fall quickly, which is beneficial to the subsequent sowing of solid fertilizers.

[0036] The auxiliary spreading mechanism 4 includes a lower feed bin 41 fixedly connected to the bottom of the storage box 1. The lower feed bin 41 is connected to the inside of the storage box 1. When the solid fertilizer in the storage box 1 enters the lower feed bin 41, the solid fertilizer will fall on the surface of the guide base 42. The lower feed bin 41 is fixedly connected to the bottom of the lower feed bin 41. Since the guide base 42 is high in the middle and low around, the falling solid fertilizer will slide evenly from the high area in the center of the guide base 42 to the surroundings, and finally fall on the low area around the guide base 42, which has a preliminary dispersion effect. The inner wall of the guide base 42 away from the center point is evenly provided with a plurality of feed holes 43, so that the solid fertilizer can continue to fall from the inside of the feed hole 43. At the same time, the plurality of feed holes 43 are conducive to the multi-directional falling of the solid fertilizer, which helps to evenly spread the solid fertilizer into the strip ditch. A slide groove 44 is provided on the inner wall at the bottom of the material guide base 42, and an opening and closing plate 45 is slidably connected inside the slide groove 44. The opening and closing plate 45 is located below the material guide base 42, and its outline diameter is consistent with the outline diameter of the material guide base 42. A pull rod 46 is fixedly connected to the top of the opening and closing plate 45, and the top end of the pull rod 46 slides through the inner wall at the top of the material guide base 42 and is fixedly connected to the bottom of the vertical rod 32. In the initial state, the top part of the opening and closing plate 45 is not pressed down by the pull rod 46 and the vertical rod 32, so that the top part of the opening and closing plate 45 is stationary inside the slide groove 44. At this time, the opening and closing plate 45 is located below the material guide base 42, and the opening and closing plate 45 is tightly fitted with the material guide base 42, so that the material discharge channel of the discharge hole 43 is blocked by the opening and closing plate 45. By using the downward pressure of the pull rod 46 on the vertical rod 32, the opening and closing plate 4 5 slides downward inside the chute 44, and at the same time separates the opening and closing plate 45 from the material guide base 42. At this time, the material discharge channel of the discharge hole 43 is reopened, so that the solid fertilizer can fall normally, and after falling on the surface of the opening and closing plate 45, it rolls into the groove synchronously, which not only increases the sowing range of the solid fertilizer, but also disperses the solid fertilizer again when falling on the surface of the opening and closing plate 45, so that the solid fertilizer is sown more evenly. At the same time, under the intermittent lifting action of the tension rod 46, the opening and closing plate 45 is intermittently in contact and separation with the material guide base 42, so that there is a material discharge interval in the discharge hole 43, so that only a small amount of solid fertilizer is discharged each time, so as to avoid excessive use of solid fertilizer. A plurality of discharge grooves 47 are evenly opened on the inner wall of the top of the opening and closing plate 45 and located below the material guide base 42;

[0037] The overall outer contour of the material guide base 42 is high in the middle and low around. The top of the opening and closing plate 45 is close to the material discharge trough 47 and is located below the material guide base 42. It is a concave surface. The outer wall of the bottom end of the opening and closing plate 45 is an inclined surface. The top of the opening and closing plate 45 and below the material discharge hole 43 are flat. A plurality of partition plates 51 are evenly fixedly connected around the top of the material guide base 42. The plurality of material discharge holes 43 are distributed between two adjacent partition plates 51. The top plane of the opening and closing plate 45 is used so that when the opening and closing plate 45 is combined with the material guide base 42, the flat surface can drop the material discharge hole 43 through the bottom of the opening and closing plate 45. The channel is closed, and when the opening and closing plate 45 is separated from the material guiding base 42, the solid fertilizer in free fall will fall into the concave area and the inclined area on the top of the opening and closing plate 45. In the concave area, the solid fertilizer in the concave surface can be dropped by utilizing the provided discharge chute 47, so as to achieve the purpose of spreading the solid fertilizer to the area below the opening and closing plate 45. The evenness of spreading the solid fertilizer can be further improved by coordinating the inclined surface with the concave surface, so that the solid fertilizer is evenly distributed in every place in the strip ditch, ensuring that after the subsequent covering with soil, it can provide good nutritional supplement for the poplar trees.

[0038] The auxiliary mixing mechanism 7 includes a fixed frame 71 symmetrically fixedly connected to the top side wall of the storage box 1, and the two fixed frames 71 are slidably connected with support rods 72 inside. The top of the support rod 72 away from the fixed frame 71 is fixedly connected to a support seat 73, and the top of the support seat 73 is rotatably connected to a rotating ring 74. The bottom of the rotating ring 74 is evenly fixedly connected to a plurality of mixing blades 75. The outer wall of the rotating shaft 2 is fixedly connected to a transmission wheel 76, and the outer wall of the transmission wheel 76 is frictionally matched with the outer wall of the rotating ring 74. The outer wall of the rotating ring 74 and the outer wall of the transmission wheel 76 The outer surfaces of the rotating ring 74 and the transmission wheel 76 are both rough. The inner wall of the fixed frame 71 is fixedly connected to a support spring 81 below the end of the support rod 72. The top of the support spring 81 is fixedly connected to the bottom of the support rod 72. The outer wall of the rotating shaft 2 is also fixedly connected to a knocking block 82 above the support rod 72. The arc end of the knocking block 82 is in conflict with the top of the support rod 72. The rotating shaft 2 is used to drive the transmission wheel 76 to rotate. Under the action of friction, the transmission wheel 76 drives the rotating ring 74 The mixing blades 75 rotate synchronously with the support seat 73 through the rotating ring 74. When multiple solid fertilizers are added into the storage box 1, a stirring effect can be achieved, so that the multiple solid fertilizers can be evenly mixed while the storage box 1 is moving above the groove. Compared with manual stirring, the user's physical strength and time are saved. In addition, when the rotating shaft 2 rotates with the knocking block 82 and contacts the top of the support rod 72, the arc-shaped end of the knocking block 82 will press down the support rod 72, causing the support rod 72 to slide downward inside the fixed frame 71. During this period, the support spring 81 will be squeezed. When the knocking block 82 separates from the support rod 72, the support rod 72 is reset due to the rebound characteristics of the support spring 81, and the rotating ring 74 and the mixing blades 75 produce a vibration effect. The above process is repeated to speed up the vibration frequency of the rotating ring 74 and the mixing blades 75, and vibrate while stirring to prevent the solid fertilizer from adhering to the surface of the rotating ring 74 and the mixing blades 75. While improving the stirring effect, it plays a self-cleaning role, which is convenient for repeated use.

[0039] The first advantage of the present invention compared with the traditional fertilizer application equipment is that the top plane of the opening and closing plate 45 is utilized so that when the opening and closing plate 45 is combined with the material guide base 42, the plane can close the falling channel of the discharge hole 43; and when the opening and closing plate 45 is separated from the material guide base 42, the solid fertilizer in free fall will fall on the concave area and the inclined area on the top of the opening and closing plate 45. In the concave area, the solid fertilizer in the concave surface can be made to fall by utilizing the provided discharge trough 47, so as to achieve the purpose of spreading the solid fertilizer in the area below the opening and closing plate 45; and the uniformity of spreading the solid fertilizer can be further improved by coordinating the inclined surface with the concave surface, so that the solid fertilizer is evenly distributed in every place in the strip ditch, so as to ensure that after the subsequent covering with soil, it can provide good nutritional supplement for the poplar trees.

[0040] Advantage two: the rotating ring 74 and the mixing blades 75 can achieve the effect of stirring and vibrating during rotation, thereby preventing solid fertilizer from adhering to the surface of the rotating ring 74 and the mixing blades 75, improving the stirring effect, and playing a self-cleaning role, which is convenient for next use.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
