Description

Technical Field

[0001] This utility model belongs to the technical field of fertilization devices, and specifically relates to an earthworm castings fertilization device for fresh tomato cultivation. Background Technology

[0002] Earthworm castings are a black, homogeneous substance with a natural earthy aroma. They have a loose, porous, granular structure, offering excellent aeration, drainage, and water retention. Due to their large surface area and colloidal network properties, earthworm castings allow many beneficial microorganisms to thrive. Earthworm castings are excellent well-rotted organic fertilizer and also contribute to the soil's granular structure. This unique physical structure and colloidal properties give them an adsorption effect, promoting crop growth and development.

[0003] Earthworm castings, due to their uneven particle size and weight, tend to separate during vibration and spreading. This results in small particles and dust accumulating in one place while larger particles remain in another, leading to poor fertilization uniformity and affecting the evenness of crop absorption. Existing high-speed rotating crushing or spreading components can break down the valuable porous aggregate structure of earthworm castings, damaging their excellent physical properties and ultimately reducing their soil-improving effects and fertilizing efficacy.

[0004] In the cultivation of fresh tomatoes, this crop has a deep root system, reaching 30-50cm, and in some cases even 150cm. Earthworm castings, used as base fertilizer, are typically applied at a depth of 20-30cm. However, existing fertilization systems generally involve first creating furrows with a ditching plow, followed by fertilization. Because soil backfilling occurs after furrow creation, the fertilizer distribution is uneven, with some fertilizer remaining deep within the soil and others on the surface. This results in uneven nutrient absorption by the tomato roots and inconsistent seedling growth. Furthermore, existing fertilization systems operate on a single-row basis, providing insufficient nutrient supply to the tomato roots and further exacerbating the uneven seedling growth. Utility Model Content

[0005] Based on this, the present invention provides an earthworm casting fertilization device for fresh tomato cultivation to solve the problems existing in the prior art. In the prior art, the fertilizer distribution after fertilization is uneven, with some fertilizer located deep in the soil and some located on the surface, resulting in uneven nutrient absorption by the roots of fresh tomatoes and uneven growth of seedlings. In addition, the existing fertilization device is a single-row fertilization device, which is insufficient in supplying fertilizer nutrients to the roots of fresh tomatoes, further aggravating the technical problem of uneven growth of seedlings.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A vermicompost fertilization device for fresh tomato cultivation includes a frame and wheels mounted on both sides of the frame, and also includes...

[0008] A fertilizer application mechanism includes a hopper, a receiving cylinder, and a double-row feeding cylinder. The hopper is mounted on the frame and has several discharge ports at its bottom. The receiving cylinder is fixedly mounted on the frame and located below the discharge ports. The double-row feeding cylinder is located below the receiving cylinder.

[0009] A secondary ditching plow is mounted on the frame and can move up and down vertically. The lower end of the double-row feed cylinder extends and is fixed to the lower bottom of the secondary ditching plow and is located behind the secondary ditching plow.

[0010] Preferably, the secondary ditching plow includes a wide row divider plate and a wide plow head. The wide row divider plate is mounted on the frame and can be raised and lowered vertically. The wide plow head is mounted at the bottom of the wide row divider plate.

[0011] Preferably, a set of limiting sleeves is provided at the bottom of the wide-row diverter plate, and the double-row feed cylinder is sleeved and limited within the set of limiting sleeves.

[0012] Preferably, the double-row feed cylinder includes a first feed cylinder and a second feed cylinder, the first feed cylinder and the second feed cylinder are arranged side by side, and the first feed cylinder and the second feed cylinder are respectively engaged and limited in the limiting cylinder.

[0013] Preferably, the frame is further provided with a limiting frame, the limiting frame is provided with fastening screws, the wide-row diverter is sleeved in the limiting frame, and the fastening screws pass through the limiting frame and engage with the wide-row diverter in a limiting fit.

[0014] Preferably, the fertilizer application mechanism further includes a guide channel, which is disposed at the bottom of the hopper and inclined directly below the discharge port.

[0015] Preferably, the guide channel and the hopper are rotatably connected via a rotating mechanism.

[0016] Preferably, the receiving cylinder is funnel-shaped.

[0017] Preferably, it further includes a low-speed feeding mechanism, which includes a rotating shaft, a flexible feeding roller, a reduction gearbox and a drive unit. The rotating shaft is disposed at the bottom of the hopper and passes through the discharge port. The flexible feeding roller is sleeved on the rotating shaft and is located inside the discharge port. The reduction gearbox is connected to the rotating shaft and is located on one side of the hopper. The drive unit is connected to the reduction gearbox.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] By setting up the secondary trenching plow and the double-row feeding cylinder, the secondary trenching plow pushes open the backfill soil, and the double-row feeding cylinder slides out earthworm castings, applying the earthworm castings to the same depth in the trench with a wide fertilization width. This ensures that the earthworm castings are applied at the same depth, and the double-row application method allows the fresh tomato roots to absorb the nutrients in the earthworm castings, resulting in more uniform seedling growth, which is easier for later pruning and maintenance. As the tomato seedlings grow, both the main root and lateral root can absorb the nutrients in the earthworm castings, avoiding nutrient deficiency in the later stages of tomato seedling growth, thereby increasing the yield of fresh tomatoes.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] A worm casting fertilization device for fresh tomato cultivation is used in conjunction with a ditching device. The ditching device and the fertilization device are driven by a tractor. After the ditching device opens the ditch, the fertilization device completes the fertilization.

[0030] Please refer to Figures 1 to 6 A vermicompost fertilization device for fresh tomato cultivation includes a frame 100 and wheels 200 mounted on both sides of the frame 100.

[0031] The fertilization mechanism 300 includes a hopper 310, a receiving cylinder 320, and a double-row feeding cylinder 330. The hopper 310 is mounted on the frame 100. The bottom of the hopper 310 has several discharge ports 311 for adding earthworm castings. Fresh tomatoes are mainly grown in greenhouses, and this fertilization device is mainly used to apply base fertilizer to the greenhouse soil. This fertilization device is a small fertilization device. Generally, the bottom of the hopper 310 has 3-4 sets of discharge ports 311, and the earthworm castings in the hopper 310 can fall from the discharge ports 311. The receiving cylinder 320 is fixedly installed on the frame 100 and is located below the discharge port 311. The receiving cylinder 320 serves to temporarily store the earthworm castings. The double-row feeding cylinder 330 is located below the receiving cylinder 320. The earthworm castings temporarily stored in the receiving cylinder 320 will enter the double-row feeding cylinder 330 and be spread evenly around the roots of the tomato seedlings in a double-row fertilization manner. This provides sufficient nutrition for the tomato seedlings, and as the tomato seedlings grow, both the main root and lateral roots of the tomato seedlings can absorb nutrients.

[0032] Specifically, the double-row feed cylinder 330 is made of transparent and elastic plastic material, or rubber material, which is elastic and stretchable to prevent the double-row feed cylinder 330 from being damaged by collision.

[0033] See Figure 1 and Figure 3 A secondary ditching plow 400 is mounted on the frame 100 and can move vertically up and down. The lower end of the double-row feed cylinder 330 extends and is fixed to the lower bottom of the secondary ditching plow 400, located behind it. Since the soil has been pre-ditched by the ditching plow, the secondary ditching plow 400 mainly serves to push away the backfill soil. Therefore, it does not need to ditch or plow the land. After pushing away the backfill soil, the double-row feed cylinder 330 behind the secondary ditching plow 400 is unaffected by the backfill soil, and the earthworm castings flowing out of the double-row feed cylinder 330 can be evenly distributed at the same depth in the furrow. Furthermore, the secondary ditching plow 400 can adjust the plowing depth according to the ditching depth of the ditching device, avoiding plowing too deep or too shallow.

[0034] By setting up the secondary trenching plow 400 and the double-row feeding cylinder 330, the secondary trenching plow 400 pushes open the backfill soil, and the double-row feeding cylinder 330 slides out earthworm castings, applying the earthworm castings to the same depth in the trench with a wide fertilization width. This ensures that the earthworm castings are applied at the same depth, and the double-row application method allows the fresh tomato roots to absorb the nutrients in the earthworm castings, resulting in more uniform seedling growth, which is easier for later pruning and management. As the tomato seedlings grow, both the main root and lateral root can absorb the nutrients in the earthworm castings, avoiding nutrient deficiency in the later stages of tomato seedling growth, thereby increasing the yield of fresh tomatoes.

[0035] In one possible embodiment, the secondary ditching plow 400 includes a wide-row diversion plate 410 and a wide plow head 420. The wide-row diversion plate 410 is mounted on the frame 100 and can move up and down vertically. The wide plow head 420 is located at the bottom of the wide-row diversion plate 410. Compared to ordinary plows, the wide-row diversion plate 410 and the wide plow head 420 are wider. Since the secondary ditching plow 400 does not need to ditch, even though the wide-row diversion plate 410 and the wide plow head 420 are wider, they can still push the backfill soil after the furrow to both sides of the furrow. The wider wide-row diversion plate 410 can clear a larger area of ​​flat furrow, and the earthworm castings flowing out from the double-row feed cylinder 330 can be evenly scattered in the furrow. Furthermore, due to the absence of backfill soil, the bottom of the double-row feed cylinder 330 is not easily blocked by soil, resulting in smoother fertilizer discharge.

[0036] In one possible embodiment, a set of limiting sleeves 411 are provided at the bottom of the wide-row diversion plate 410, and the double-row feed cylinder 330 is sleeved and limited within the set of limiting sleeves 411. The size of the limiting sleeve 411 is adapted to the size of the double-row feed cylinder 330, which can firmly lock the double-row feed cylinder 330 into the limiting sleeve 411. The limiting sleeve 411 mainly serves to fix the double-row feed cylinder 330 and can ensure that the double-row feed cylinder 330 is located behind the wide-row diversion plate 410, so that soil will not block the bottom of the double-row feed cylinder 330.

[0037] In one possible embodiment, the dual-row feed cylinder 330 includes a first feed cylinder 331 and a second feed cylinder 332, which are arranged side by side and respectively engaged and confined within the limiting cylinder 411. The side-by-side arrangement of the first feed cylinder 331 and the second feed cylinder 332 enables the earthworm castings to be evenly spread in the furrow.

[0038] In one possible embodiment, a limiting frame 110 is further provided on the frame 100, and a fastening screw 120 is provided on the limiting frame 110. The wide-row diverter plate 410 is sleeved within the limiting frame 110, and the fastening screw 120 passes through the limiting frame 110 and engages with the wide-row diverter plate 410 for limiting. By adjusting the up-and-down movement of the wide-row diverter plate 410 within the limiting frame 110, and fixing the wide-row diverter plate 410 within the limiting frame 110 by the fastening screw 120, the height of the secondary ditching plow blade 400 can be adjusted.

[0039] In one possible embodiment, the fertilization mechanism 300 further includes a guide channel 340, which is groove-shaped and located at the bottom of the hopper 310, inclined directly below the discharge port 311. Earthworm castings falling from the discharge port 311 slide down the guide channel 340, allowing workers to observe the descent of the castings and promptly clear any blockages in the discharge port 311 within the hopper 310.

[0040] In a preferred embodiment, when the hopper 310 is not fertilizing, to prevent the earthworm castings in the hopper 310 from falling, the guide channel 340 is rotatably connected to the hopper 310 via a rotating mechanism 341. When the hopper 310 is not fertilizing, the guide channel 340 is rotated clockwise so that its bottom contacts the bottom of the discharge port 311, forming a closed state, and is limited by the rotating mechanism 341 to prevent the earthworm castings in the hopper 310 from scattering onto the ground. When fertilization is required, the tilt angle of the guide channel 340 is adjusted by the rotating mechanism 341, and the guide channel 340 is rotated counterclockwise so that one end of the guide channel 340 faces the receiving cylinder 320, allowing the earthworm castings to slide along the guide channel 340 into the receiving cylinder 320. By setting the rotating mechanism 341, the earthworm castings can be controlled to be in a scattered or closed state.

[0041] Specifically, the rotation mechanism 341 limits the control of the guide channel 340 in an existing structure, such as a one-way rotating ratchet or a rotating latch, or even a small rotating motor can be used to adaptively control the rotation of the guide channel 340.

[0042] In a preferred embodiment, the receiving cylinder 320 is funnel-shaped, which serves to temporarily store a large amount of earthworm castings and prevent the earthworm castings from accumulating and scattering on the ground.

[0043] In one possible embodiment, see Figure 5 and Figure 6Because earthworm castings have uneven particle size, to prevent uneven particle size and weight, and to avoid high-speed rotating crushing or scattering components breaking the earthworm castings, thus preserving their porous granular structure, a low-speed feeding mechanism 500 is also included. This mechanism includes a rotating shaft 510, a flexible feeding roller 520, a reduction gearbox 530, and a drive unit 540. The rotating shaft 510 is located at the bottom of the hopper 310 and extends through the discharge port 311. The flexible feeding roller 520 is sleeved on the rotating shaft 510 and located within the discharge port 311. The surface of the flexible feeding roller 520 is relatively soft, and the flexible feeding roller 520 is located within the... Inside the feeding port 311, when the flexible feeding roller 520 is not rotating, it prevents a large amount of earthworm castings from falling from the feeding port 311. When the flexible feeding roller 520 rotates in the feeding port 311, each rotation of the flexible feeding roller 520 will cause some earthworm castings to fall from the feeding port 311, achieving the purpose of quantitative and uniform fertilization. At the same time, during the rotation of the flexible feeding roller 520, large pieces of earthworm castings will be removed by the flexible feeding roller 520. The flexible feed roller 520 presses against the side wall of the hopper 310, breaking up large pieces of earthworm castings. Furthermore, because the surface of the flexible feed roller 520 is relatively soft, while it presses against the side wall of the hopper 310, it does not apply a rigid pressure. Larger earthworm castings will cause the flexible feed roller 520 to shrink and deform, preventing it from being severely crushed and preserving its porous granular structure. The reduction gearbox 530 is connected to the rotating shaft 510 and is located on one side of the hopper 310. The drive unit 540 is connected to the reduction gearbox 530. When the drive unit 540 rotates, its transmission speed is reduced by the reduction gearbox 530, causing the drive shaft connected to the reduction gearbox 530 to rotate slowly, not at high speed. Because the flexible feed roller 520 is rotating at a low speed, it further prevents the earthworm castings from being severely crushed by high-speed rotation, thus preserving their porous granular structure.

[0044] Specifically, the flexible feeding roller 520 is in a low-speed rotation state, with a rotation speed of 60-100 rpm.

[0045] Specifically, a fertilizer gap is reserved between the flexible feeding roller 520 and the side wall of the discharge port 311 of the hopper 310 to prevent earthworm fertilizer from clogging in the hopper 310. The reserved fertilizer gap also helps the flexible feeding roller 520 to squeeze and break up large pieces of earthworm fertilizer.

[0046] Specifically, the reduction gearbox 530 is an existing reduction device, which will not be described in detail here.

[0047] Specifically, the drive unit 540 can be an existing drive motor, or the drive unit 540 can be a drive gear, which is connected to the rotating part of the tractor to drive the drive gear to rotate, thereby driving the rotating shaft 510 to rotate.

[0048] In one possible embodiment, see Figure 6 The flexible feeding roller 520 includes a rotating cylinder 521 and flexible feeding plates 522. The rotating cylinder 521 is fixedly sleeved on the rotating shaft 510. The rotating cylinder 521 is made of iron or a high-strength plastic material. The rotating cylinder 521 and the rotating shaft 510 are fixedly sleeved by one of the following methods: screw engagement, pin engagement, or screw tightening. This fixing method prevents relative rotation between the rotating cylinder 521 and the rotating shaft 510. The rotating cylinder 521 is located inside the feed inlet 311. Several sets of flexible feeding plates 522 are provided and are evenly engaged on the outer surface of the rotating cylinder 521. As the rotating cylinder 521 drives the rotating shaft 510... As the flexible feeding plate 522 rotates, earthworm castings accumulate between adjacent sets of flexible feeding plates 522. With the rotation of the flexible feeding plate 522, the accumulated earthworm castings are discharged from the discharge port 311. Simultaneously, large pieces of earthworm castings are caught between adjacent sets of flexible feeding plates 522. During the rotation of the rotating cylinder 521, the rotating cylinder 521, the flexible feeding plates 522, and the side wall of the hopper 310 compress the earthworm castings, achieving the effect of breaking up large pieces of earthworm castings. Furthermore, during the compression of large pieces of earthworm castings, due to the elasticity of the flexible feeding plate 522, the earthworm castings compress and deform under the pressure of the flexible feeding plate 522, resulting in non-rigid compression and preventing significant crushing of the earthworm castings.

[0049] Specifically, a limiting groove is provided on the rotating cylinder 521, and the flexible feeding plate 522 is engaged in the limiting groove.

[0050] In a preferred embodiment, the flexible feeding roller 520 further includes a limiting screw 523, which passes through the rotating cylinder 521 and engages with the rotating shaft 510 for limiting. Simultaneously, the flexible feeding plate 522 is also fixed to the outer wall of the rotating cylinder 521 to prevent the rotating cylinder 521 and the flexible feeding plate 522 from shaking during the rotation of the rotating shaft 510.

[0051] In a preferred embodiment, the flexible material-pulling plate 522 has a triangular cross-section. A set of the flexible material-pulling plates 522 can better hold large pieces of earthworm castings.

[0052] In a preferred embodiment, the flexible material feeding plate 522 is one of a flexible plastic plate or a flexible rubber plate. It has high elasticity, preventing earthworm castings from being severely crushed.

[0053] In one possible embodiment, positioning seats are provided on both sides of the frame 100, and bearings are nested within the positioning seats. The rotating shaft 510 passes through the bearings and is interlocked with them. The positioning seats can provide stable support for the rotating shaft 510.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
