A method of growing white celery based on a growing box

Abstract

This application discloses a method for cultivating white celery using planting boxes, including the steps of planting, transplanting, mounding, and harvesting using specially designed planting boxes. The planting boxes are designed for mechanized operation, and are efficiently planted into the planting ridges using a transplanting and planting machine. During mounding, a transplanting and mounding machine sorts the celery and creates a descent trench below the planting box, allowing the planting box and white celery to sink naturally. During harvesting, a harvesting machine breaks the soil and circumferentially cuts the white celery roots outside the planting box, and then lifts the planting box using a U-shaped conveyor chute to harvest the white celery. This method eliminates the need for large-scale soil removal, increases the effective planting area and thus increases yield, reduces costs, and yields significant economic benefits. Mechanized operation throughout the process reduces manual labor intensity and improves operational efficiency. It also ensures the whitening effect of the white celery. Compared to traditional methods, this invention enables large-scale, factory-style cultivation, reduces labor costs, improves the working environment for farmers, and maximizes the economic benefits of white celery cultivation.

Description

Technical Field

[0001] This invention relates to the field of celery cultivation technology, specifically to a method for cultivating celery using a planting box. Background Technology

[0002] Liyang white celery, a traditional specialty agricultural product of Liyang City with a long history, can be traced back more than 800 years. Thanks to its unique cultivation techniques and superior quality, Liyang white celery obtained the geographical indication registration and protection certification for agricultural products on December 24, 2010. Its cultivation method is unique: after the water celery has grown to about 30 to 35 centimeters in dry conditions, it undergoes artificial deep mounding of soil, allowing the celery stalks to continue growing in a dark, sealed soil environment and bleach, hence the name "white celery." With its jade-white stalks, golden celery buds, and unique flavor that is slightly sweet, not greasy, and crisp and refreshing, white celery is hailed as a delicacy among the delicacies of Jiangnan.

[0003] However, traditional Liyang white celery cultivation methods face numerous challenges. Around the time of the White Dew solar term each year, growers need to cultivate long, narrow celery seedlings in advance and plant them horizontally on raised beds. When the celery reaches the appropriate height, a laborious manual soil-filling process is required. This process uses wooden boards as templates, requiring multiple people to work together to fill and compact the soil, resulting in extremely high labor intensity and low efficiency. Even more challenging is the harvesting of white celery, which must be done in the dead of winter. Growers must wash the celery by hand in icy water, further increasing labor intensity and limiting production efficiency. Therefore, the high cost and harsh conditions of the manual soil-filling and harvesting stages under traditional methods discourage young people from pursuing this industry, hindering the sustainable development of the Liyang white celery industry.

[0004] To address the shortcomings of traditional planting methods, preliminary explorations have been conducted on existing mechanized planting technologies. For example, the celery seed metering machine with patent number ZL201610099159.2, although it mechanizes multiple processes such as fertilization, ridging, ditching, seed metering, and soil covering, has a different seed metering process than the method in this patented invention, and its planting efficiency is low, the planting quality is poor, and it cannot achieve the goal of factory-style planting.

[0005] Furthermore, while the celery-specific soil-mulching machine with patent number ZL201510801031.1 and the four-row, three-ridge celery-specific soil-mulching machine with application number 2023107832582 employ mechanical spiral soil-removing and mounding technology, they still have many shortcomings. For example, they require large soil removal volumes and large pre-reserved furrow areas, leading to a reduction in effective planting area and yield; their complex mechanisms place high demands on the equipment; their mounding efficiency is low, and their sealing effect is poor, affecting the quality and appearance of the celery; and they cannot achieve the goal of mechanized, continuous, and rapid harvesting of celery. Therefore, existing mechanized planting technologies still need further improvement and refinement. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a method for growing white celery based on a planting box.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a method for planting white celery based on a planting box, specifically including the following steps:

[0008] Step 1: First, plant the celery seeds in a planting box with nutrient soil, and then transplant them onto the planting ridge.

[0009] Step 2: Use a planting box transplanting and seeding machine to move the planting boxes that have been planted with celery seeds in Step 1 to the planting ridge for seeding. The planting ridge is a two-row planting ridge.

[0010] Step 3: When the white celery has grown and needs to be mounded with soil, use a transplanting mounding machine to create a drop trench under the planting box so that the celery can fall into the drop trench to achieve the purpose of mounding with soil.

[0011] Step 4: Use a celery harvester to remove the planting box along with the celery from the planting ridge.

[0012] Furthermore, the planting box includes a long box body, which is 70 cm long, 7 cm wide, and 10 cm high. The bottom and both sides of the long box body are provided with long waist holes for the celery roots to grow out of the long box body. The bottom of the inner cavity of the long box body is also provided with several reinforcing ribs, and the two ends of the long box body are respectively provided with buckle plates and buckle interfaces that fasten with the buckle plates.

[0013] Furthermore, the planting box transplanting and seeding machine specifically comprises: a first frame, a pre-ditching mechanism, a ditch forming device, a planting box conveying slide, a rolling compaction device, a planting box stacking platform, and a first manual operation platform;

[0014] The first frame is connected to the tractor;

[0015] The pre-grooving mechanism includes two grooving cutter groups arranged opposite to each other at the front end of the first frame;

[0016] The groove forming device includes a groove forming shaft rotatably mounted on the first frame. The groove forming shaft is provided with two forming rings, and the positions of the two forming rings correspond one-to-one with the positions of the two groove opening blades.

[0017] Both ends of the groove forming shaft are equipped with ridging conical discs, and one end of the groove forming shaft is also equipped with a sprocket that cooperates with the tractor transmission system.

[0018] The planting box conveyor slide is designed with two U-shaped structures. The upper end of the slide is fixed to the upper part of the first frame, while the lower end is installed on the lower part of the first frame. After installation, the center line of the two planting box conveyor slides coincides with the center line of the pre-ditch formed by the forming ring on the ridge surface.

[0019] The planting box stacking platform is located in the upper area of ​​the first frame, while the first manual operation platform is located in the lower area of ​​the first frame.

[0020] The rolling compaction device consists of a rolling shaft rotatably mounted at the rear end of the first frame.

[0021] Furthermore, the transplanting and mounding machine includes a second frame, two sets of combing mechanisms, two sets of ditching mechanisms, two anti-side collapse baffles, and a ridging and compaction device;

[0022] The second frame is connected to the tractor;

[0023] The combing mechanism includes two pairs of conical combing heads, two sets of front clamps, two sets of rear clamps, and two sets of tail clamps mounted on a second frame. The ends of the two pairs of conical combing heads are fixed to the front of the second frame and transitionally connected to the corresponding front clamps. The two conical combing heads in the same set span the celery roots on the ridge surface on both sides. The distance between the cones of the two conical combing heads in the same set is 12 cm, and the distance between the cone tails is 6 cm. The two conical combing heads in the same set present a symmetrical flared cone shape, and their forward direction also adopts a flared cone shape. The width of the flared mouth formed by the two conical combing heads gradually narrows from front to back until it matches the width of the two front clamps. At the same time, in the height direction, the flared cone of the conical combing head gradually rises to the height of the front clamp and finally smoothly transitions to the front clamp.

[0024] The trenching mechanism includes a separating ring cutter, a first plow blade, a second plow blade, and a third forming plow blade, which are arranged sequentially from front to back on the second frame. The separating ring cutter includes a ring cutter shank and a ring cutter head disposed at the lower end of the ring cutter shank. The ring cutter shank consists of two ring cutter steel plates fixed to the second frame, and the inner cavity of the ring cutter shank is used to fix the front clamping plate. The ring cutter head is U-shaped, and one end is a cutting edge structure.

[0025] The first plow blade, the second plow blade, and the third shaped plow blade are all composed of a plow blade head and a plow blade handle. The plow blade handle consists of two plow blade steel plates mounted on the second frame. The inner cavity between the two plow blade steel plates is used to fix two front clamping plates so that a first channel can be formed between the two front clamping plates to allow the white celery to pass through in an upright state. A second channel for the planting box to pass through is also formed between the upper end of the plow blade head and the two plow blade steel plates on both sides.

[0026] The upper part of the front end of the rear splint is connected to the plow handle of the third shaping plow blade and integrally connected to the front splint. Its lower part extends into the rear end of the plow blade head of the third shaping plow blade and is connected to it. The upper part of the rear upper part of the rear splint is connected to the second frame, and the front end of the tail end splint is integrally connected to the rear end of the rear splint. The upper part of the tail end splint is 2 cm higher than the ridge surface, and the lower part is flush with the bottom of the rear splint;

[0027] The two anti-collapse baffles are respectively installed on both sides of the second frame and are used to prevent the ridge surface from collapsing due to the forward extrusion of the soil by the ditch-opening mechanism;

[0028] Further, the ridge closing and compressing device includes a hinged tie rod mechanism and a ridge closing and compressing component;

[0029] The hinged tie rod mechanism is composed of two hinged tie rods. One end of each of the two hinged tie rods is hinged to the second frame, and the ends away from the second frame are respectively hinged to both sides of the upper end of the ridge closing and compressing component;

[0030] The ridge closing and compressing component includes a middle steel plate and side steel plates respectively arranged on both sides of the middle steel plate. There are through grooves coinciding with the center line of the tail end splint between the middle steel plate and the side steel plates on both sides, and the sides of the two tail end splints in the same group are respectively clamped on both sides of the through grooves. The upper ends of the two through grooves connect the middle steel plate and the side steel plates on both sides into one body through U-shaped members. And the lower ends of the side steel plates on both sides are provided with side pressing plates with the same angle as the side of the planting ridge. The front and rear ends of the side steel plates are respectively provided with fixed bolts and adjusting bolts. The front and rear ends of the side pressing plates are respectively provided with circular holes and long waist-shaped holes, and the fixed bolts and adjusting bolts are respectively placed in the circular holes and long waist-shaped holes to adjust the opening size between the two side pressing plates, so as to adjust the distance between the rear ends of the two side pressing plates to close the ridge surface.

[0031] Further, the white celery harvesting and starting machine includes a third frame and two soil-breaking plow blade groups, two circumcision knife devices, two starting and harvesting U-shaped conveying chutes and a second manual operation platform arranged on the third frame;

[0032] The two soil-breaking plow blade groups are respectively installed at the front and rear positions of the bottom of the third frame, and the lateral positions correspond to the side positions of two rows of planting boxes. The soil-breaking plow blade group includes a front plow blade and a rear plow blade, and both the front plow blade and the rear plow blade are fixed to the third frame through U-shaped clamps;

[0033] The two circumcision knife devices are respectively installed behind the corresponding soil-breaking plow blade groups. It includes a mounting plate and a circumcision knife fixed on the mounting plate. The circumcision knife is connected to the third frame through the mounting plate. The circumcision knife is in an "L" shape and can surround the planting box on three sides;

[0034] The two U-shaped conveyor chutes are respectively installed behind the corresponding ring cutter devices. The rear end of the U-shaped conveyor chutes is higher than the front end. The U-shaped conveyor chutes are inclined on the left and right in cross-section so that the celery on the planting box can tilt to one side and prevent the celery from breaking during the conveying process. The U-shaped conveyor chutes form a certain angle with the direction of travel to promote the smooth separation of the planting box from the soil.

[0035] Furthermore, the specific steps of step one are as follows:

[0036] Fill the prepared nutrient soil with a certain viscosity into the long box to the height of the reinforcing ribs, and lay the pre-grown celery seedlings on the nutrient soil according to the required quantity.

[0037] Then, cover the celery with nutrient soil until it is level with the opening of the long box, forming a soil layer. Then, spray an appropriate amount of water on the soil layer and press the surface flat.

[0038] Furthermore, the specific steps of step two are as follows:

[0039] The entire first frame is connected to the tractor, and the entire planting box transplanting and seeding machine is pulled forward by the tractor. During the forward movement, the ditching blades cut into the ridge surface and, as the machine moves forward, initially open two preparatory furrows that meet the requirements of the planting row spacing and the preset width and height of the planting box.

[0040] When the power drive chain on the tractor drives the sprocket and the sprocket drives the groove forming shaft to rotate, the two forming rings on the groove forming shaft overlap and roll in the preparatory groove initially opened by the aforementioned grooving cutter to form a planting groove that is suitable for planting box insertion.

[0041] At the start of the operation, a person manually inserts the first planting box into the planting groove of the planting ridge. The second planting box and other planting boxes are then connected end to end in the planting box conveyor slide. As the entire planting box transplanting and seeding machine moves forward, the person on the first manual operation platform inserts the planting boxes into the planting grooves one by one through the corresponding planting box conveyor slide. At the same time, the ridge forming shaft at both ends rotates the ridge conical discs to keep the ridge sides in their original shape.

[0042] Furthermore, the specific steps of step three are as follows:

[0043] The entire second frame is connected to the tractor. Two pairs of conical combing heads can pre-comb the celery into an upright position. The ring cutter head surrounds the planting box, and during the forward movement, the ring cutter head can cut off the celery roots on three sides of the planting box and separate them from the soil.

[0044] At this point, the first, second, and third shaping plows are all in the soil below the planting box, and can sequentially squeeze the soil directly below the planting box to both sides to form a falling trench with the same cross-sectional dimensions as the corresponding plow. The width of the first plow is 1 / 3 of the width of the falling trench, and the height is 1 / 2 of the depth of the falling trench; the width of the second plow is 2 / 3 of the width of the falling trench, and the height reaches the required depth of the falling trench; the third shaping plow is a shaping plow, wider than the width of the planting box, with a bottom cross-section that is an inverted triangular cone suitable for the falling space of broken soil, and the height is the required soil depth for white celery plus the height of the inverted triangular cone.

[0045] The planting box falls into the ditch under gravity. Then, by adjusting the distance between the tails of the side plates on both sides of the ridge compaction device, the soil on the sides of the two ridges is moved and gathered towards the middle. The soil on the ridge surface can be compacted by adjusting the weight of the counterweight on the ridge compaction device, so that the gap between the top of the celery and the soil mounds on both sides is controlled at 3-4 cm.

[0046] Furthermore, step four specifically involves the following steps:

[0047] When it's time to start harvesting, connect the third frame to the tractor, start the tractor to drive the third frame forward. As the third frame moves forward, the front and rear soil-breaking plow blades break the soil on the sides of the two rows of planting boxes. Specifically, the front plow blades cut off the top 2 / 3 of the soil clods, and the lower part of the front plow blades can break the soil 2-3 cm below the bottom of the planting box and discharge the soil towards the furrow. The rear plow blades remove the remaining collapsed soil clods and discharge the soil towards the furrow, so that the celery and one side of the planting box are completely exposed.

[0048] As the celery harvester moves forward, the ring cutter surrounds the planting box on three sides, removing any celery roots extending outside the box and supporting the box as it moves forward. As it continues forward, the planting box enters the U-shaped conveyor chute and is transported backward, allowing it to be lifted off the side without soil clogging and the planting ridge surface. Because the rear end of the U-shaped conveyor chute is higher than the front end, the planting box can move relatively upward, facilitating manual collection from the second manual operating platform.

[0049] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0050] (1) By using a planting box with elongated waist holes, the present invention enables factory-scale seeding and planting, thereby improving planting efficiency and quality. The overlapping design at both ends of the planting box allows the boxes to be connected end to end, forming continuous planting rows, which facilitates mechanized operation.

[0051] (2) This invention achieves full mechanization of the entire process from rotary tillage and ridging, seeding and transplanting, soil-filling transplanting and harvesting by using a combination of mechanized devices such as rotary tillage and ridging machine, transplanting and soil-filling machine, and celery harvesting machine, which greatly reduces manual labor and labor intensity and improves work efficiency.

[0052] (3) This invention ensures that the width and depth of the trench meet the requirements of the planting box through precise control of the pre-ditching mechanism and the trench forming device. The rolling and compacting device ensures that the planting box can be stably placed on the planting ridge after transplanting into the trench, avoiding poor plant growth due to soil loosening. The anti-collapse baffle of the transplanting and mounding machine ensures that the soil on both sides of the trench will not collapse. The ridge compaction device and the tail clamp work together to gather the soil on both sides towards the middle of the ridge and compact the ridge surface, so that the gap between the celery falling into the trench and the mounding soil on both sides meets the requirements, so as to achieve the best sealing effect. This allows the celery to be fully whitened when growing in the trench, ensuring the whitening effect of the white celery. The tail clamping plate isolates the celery from the mounding soil on both sides to prevent soil from entering the internal void area of ​​the celery due to compression, affecting the appearance quality of the white celery and subsequent harvesting operations.

[0053] (4) Compared with the traditional method of planting celery, which requires a lot of manual labor for soil preparation and harvesting, the use of the planting box and mechanized device in this invention significantly reduces the need for manual labor and lowers labor costs. The celery harvesting machine is equipped with front and rear soil-breaking plows and harvesting ring cutters to harvest celery by harvesting the planting box, so that celery can be harvested completely and without damage in a short time, reducing harvesting time. Mechanized operation also avoids the situation of heavy physical labor in the cold season in the traditional method, improving the working environment of farmers.

[0054] (5) Compared with existing mechanized planting methods, it reduces the reserved area of ​​furrows, ensures the maximum effective planting area per mu, and significantly increases the yield per mu, thereby increasing income. Attached Figure Description

[0078] The present invention will now be described in further detail with reference to the accompanying drawings.

[0079] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0080] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0081] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0082] This invention relates to a method for growing white celery using a planting box, specifically including the following steps:

[0083] Step 1: First, plant 37 celery seeds in planting box 1 with nutrient soil, and then transplant them to planting ridge 2.

[0084] Step 2: Using a planting box transplanting and seeding machine, the planting box 1, which has been planted with celery seeds 37 in Step 1, is moved to the planting ridge 2 for seeding. The planting ridge 2 is a two-row planting ridge. In this embodiment, the planting ridge 2 is 30 cm high, 50 cm wide at the top, 90 cm wide at the bottom, 60 cm wide at the furrow, 20 cm between rows, and 15 cm between the rows. The planting length per mu is 888 meters.

[0085] Step 3: When the white celery grows up and needs to be mounded, use a transplanting mounding machine to open a drop trench 3 under the planting box 1, so that the celery can fall into the drop trench 3 to achieve the purpose of mounding.

[0086] Step 4: Use a celery harvester to remove the planting box 1, which has been filled with soil, along with the celery from planting ridge 2.

[0087] The design of planting box 1 is crucial in the process of growing white celery using planting box 1. (See attached image.) Figure 1 -Appendix Figure 3 As shown, in this embodiment, the planting box 1 adopts the form of a long box body 101, with specific dimensions of 70 cm in length, 7 cm in width, and 10 cm in height. This design facilitates operation and provides ample growing space for the celery. Long waist holes 102 are provided at the bottom and sides of the long box body 101. This design aims to promote the growth of celery roots outwards from the box body, enhancing root stability and absorption capacity. Furthermore, several reinforcing ribs 103 are provided at the bottom of the inner cavity of the long box body 101 to enhance the structural strength of the entire long box body 101 and serve as depth positioning lines for celery planting. To facilitate the continuous application of the planting box 1 to mechanized operations, fastening plates 104 and corresponding fastening interfaces are provided at both ends of the long box body 101, allowing multiple planting boxes 1 to be securely connected together.

[0088] As attached Figure 4 -Appendix Figure 8As shown, to achieve efficient transplanting and planting of planting boxes 1, this embodiment provides a planting box transplanting and planting machine. The planting box transplanting and planting machine specifically comprises: a first frame 4, a pre-ditching mechanism, a trench forming device, a planting box conveying slide 5, a rolling compaction device, a planting box stacking platform, and a first manual operation platform. The first frame 4 is connected to a tractor, providing power to the entire device. The pre-ditching mechanism includes two trenching blades 6 positioned opposite each other at the front end of the first frame 4, which can initially create pre-ditches. The trench forming device includes a trench forming shaft 7 rotatably mounted on the first frame 4. The trench forming shaft 7 has two forming rings 8, and the positions of the two forming rings 8 correspond one-to-one with the positions of the two trenching blades 6. The forming rings 8 can compact and form planting trenches suitable for the planting box 1. Both ends of the trench forming shaft 7 are equipped with ridging conical discs 9, and one end of the trench forming shaft 7 is also equipped with a sprocket that cooperates with the tractor's transmission system. The planting box conveyor chute 5 has two U-shaped structures. The upper end is fixed to the upper part of the first frame 4, while the lower end is installed on the lower part of the first frame 4. The center lines of the two planting box conveyor chute 5, after installation, coincide with the center line of the pre-groove formed by the forming ring 8 on the ridge surface. This ensures that the planting box 1 can smoothly slide from the planting box conveyor chute into the planting grove. The planting box stacking platform is located in the upper area of ​​the first frame 4, while the first manual operation platform is located in the lower area of ​​the first frame 4. The rolling compaction device consists of a rolling shaft 10 rotatably mounted at the rear end of the first frame 4. As the entire planting box transplanting and seeding machine moves forward, the bottom surface of the rolling shaft 10 presses against the ridge surface, ensuring that the two rows of planting boxes 1 are on the same plane through the rolling of the rolling shaft 10. This ensures the smooth completion of subsequent processes and good adhesion between the planting box 1 and the ridge surface soil, ensuring a good growing environment for the celery inside the planting box 1.

[0089] As the white celery grows, the process of mounding soil around it becomes particularly important. (See attached image.) Figure 9 -Appendix Figure 19 As shown, the transplanting and mounding machine provided in this embodiment includes a second frame 11, two sets of combing mechanisms, two sets of ditching mechanisms, two anti-side collapse baffles 20, and a ridge compaction device.

[0090] The second frame 11, as the core support structure of the entire machine, is firmly connected to the tractor, ensuring stability and flexibility during operation. The combing mechanism includes two pairs of conical combing heads 12 (each pair of conical combing heads 12 consists of two symmetrically installed conical combing heads) mounted on the second frame 11, two sets of front clamping plates 13, two sets of rear clamping plates 14, and two sets of tail clamping plates 15. The ends of the two pairs of conical combing heads 12 are fixed to the front of the second frame 11 and transitionally connected to the corresponding front clamping plates 13. The two conical combing heads 12 in the same set span the celery roots on both sides of the ridge surface. The distance between the heads is 12 cm, and the distance between the cone tails is 6 cm. The two conical combing heads 12 in the same group present a symmetrical flared cone shape, and their forward direction also adopts a flared cone shape. The width of the flared mouth formed by the two conical combing heads 12 gradually narrows from front to back until it matches the width of the two front clamping plates 13. At the same time, in the height direction, the flared cone of the conical combing head 12 gradually rises to the height of the front clamping plate 13, and finally smoothly transitions to the front clamping plate 13. The design of the combing mechanism is particularly ingenious. The combination of the two pairs of conical combing heads 12 and their matching clamping plates can effectively comb the celery to keep it in an upright position, avoid tangling, and allow it to fall smoothly into the trench for a good soil-filling effect, thereby ensuring the internal and external quality of the celery and reflecting a humanized design concept.

[0091] The trenching mechanism includes a separating ring blade 16, a first plow blade 17, a second plow blade 18, and a third forming plow blade 19, which are arranged sequentially from front to back on the second frame 11. The separating ring blade 16 includes a ring blade handle 161 and a ring blade head 162 disposed at the lower end of the ring blade handle 161. The ring blade handle 161 consists of two ring blade steel plates fixed on the second frame 11, and the inner cavity of the ring blade handle 161 is used to fix the front clamping plate 13. The ring blade head 162 is U-shaped and has a blade structure at one end, which can quickly and accurately cut the external root system of the planting box 1, so that the planting box 1 is completely separated from the soil, preparing it to fall smoothly after trenching.

[0092] The first plow blade 17, the second plow blade 18, and the third forming plow blade 19 are all composed of a plow blade head 21 and a plow blade handle 22. The first plow blade 17, the second plow blade 18, and the third forming plow blade 19 are designed in a progressive manner, reducing the difficulty of trench forming and ensuring the quality of trenching by the third forming plow blade 19. The plow blade handle 22 consists of two plow blade steel plates mounted on the second frame 11. The inner cavity between the two plow blade steel plates is used to fix the two front clamping plates 13, forming a first channel 23 between the two front clamping plates 13 that allows the celery to pass through in an upright position. A second channel 24 for the planting box 1 to pass through is also formed between the upper end of the plow blade head 21 and the two plow blade steel plates. The combination of the plow blade head 21 and the plow blade steel plates ensures the stability of the structure while providing sufficient space for the passage of the celery and the planting box 1.

[0093] The upper front part of the rear clamping plate 14 is connected to the plow handle 22 of the third forming plow blade 19, and its lower part extends into and connects to the rear end of the plow head 21 of the third forming plow blade 19. The upper rear part of the rear clamping plate 14 is connected to the second frame 11, and the front end of the tail clamping plate 15 is integrally connected to the rear end of the rear clamping plate 14. The tail clamping plate 15 can move forward from the rear clamping plate 14, with a height 2-3 cm higher than the ridge surface. The bottom is flush with the lower end of the rear clamping plate 14. This forms a channel from the conical combing head 12, the front clamping plate 13, the rear clamping plate 14 to the tail clamping plate 15 that allows the celery to pass through. This allows the celery to fall smoothly into the furrow in an upright state and achieve a good soil compaction effect, thereby ensuring the internal and external quality of the celery.

[0094] Two anti-collapse baffles 20 are installed on both sides of the second frame 11. The anti-collapse baffles 20 are designed to prevent the lateral pressure that the ditching mechanism may exert on the side of the ridge during operation. By effectively blocking the lateral movement of the soil, the collapse of the ridge surface is prevented, thus ensuring the continuity and stability of the operation.

[0095] In one embodiment of this application, the ridge compaction device includes a hinged tie rod mechanism and a ridge compaction component; the hinged tie rod mechanism consists of two hinged tie rods 25, one end of each of the two hinged tie rods 25 is hinged to the second frame 11, and the ends away from the second frame 11 are respectively hinged to the upper sides of the ridge compaction component; the design of the hinged tie rod mechanism ensures that the ridge compaction component can move flexibly in the vertical direction, effectively controlling the degree of ridge surface compaction.

[0096] The ridge compaction component includes a central steel plate 26 and side steel plates 27 respectively located on both sides of the central steel plate 26. A through groove 28 coinciding with the center line of the tail end clamping plate 15 is left between the central steel plate 26 and the two side steel plates 27. The two tail end clamping plates 15 in the same group are respectively clamped on both sides of the through groove 28. The upper ends of the two through grooves 28 are connected to the central steel plate 26 and the two side steel plates 27 by U-shaped components 29. The lower ends of the two side steel plates 27 are provided with side pressure plates 30 with the same angle as the side of the planting ridge 2. The front and rear ends of the side steel plates 27 are respectively provided with fixing bolts and adjusting bolts. The front and rear ends of the side pressure plates 30 are respectively provided with circular holes and elongated arc holes. The fixing bolts and adjusting bolts are respectively placed in the circular holes and elongated arc holes to adjust the opening size between the two side pressure plates 30, thereby adjusting the distance between the rear ends of the two side pressure plates 30 to close the ridge surface. This design not only improves the adaptability and flexibility of the device, but also ensures the quality and efficiency of the compaction operation, providing a good sealed environment for the subsequent whitening growth of celery.

[0097] As attached Figure 20 -Appendix Figure 22As shown in the figure, in an embodiment of the present application, the white celery harvesting machine includes a third frame 31, two soil-breaking plow blade groups, two circumferential cutting knife devices, two U-shaped conveying chutes 32 for harvesting, and a second manual operation platform arranged on the third frame 31; the two soil-breaking plow blade groups are respectively installed at the front and rear positions at the bottom of the third frame 31, and the lateral positions correspond to the side positions of two rows of planting boxes 1. The soil-breaking plow blade group includes a front plow blade 33 and a rear plow blade 34, and both the front plow blade 33 and the rear plow blade 34 are fixed to the third frame 31 through U-shaped clamps; the third frame 31 serves as the basic support structure of the entire harvesting machine, not only firmly carrying various functional components, but also ensuring the stability and efficiency during the operation process. The design of the two soil-breaking plow blade groups is ingeniously installed at the front and rear positions at the bottom of the third frame 31, and their lateral positions precisely correspond to the sides of two rows of planting boxes 1. Such a layout can effectively reduce the damage to white celery during soil breaking. The fixing method of the front plow blade 33 and the rear plow blade 34 through U-shaped clamps not only ensures the convenience of installation, but also facilitates the later maintenance and replacement. This design not only enhances the soil-breaking effect but also improves the durability of the whole machine.

[0098] As a key component during the harvesting process, the circumferential cutting knife device is installed behind the corresponding soil-breaking plow blade group, ensuring the coherence of the soil-breaking and circumferential cutting actions. The mounting plate 35 serves as the support platform for the circumferential cutting knife 36 and is connected to the third frame 31 through precise design, ensuring the stability and accuracy of the circumferential cutting knife 36 during operation. The circumferential cutting knife 36 with a "L" shape can surround the planting box 1 on three sides, effectively cutting off the roots of the white celery to separate it from the soil, achieving the purpose of harvesting the white celery in the planting box 1. This design not only improves the harvesting efficiency but also ensures that the white celery is not damaged. The two U-shaped conveying chutes 32 for harvesting are respectively installed behind the corresponding circumferential cutting knife devices. The rear end of the U-shaped conveying chute 32 for harvesting is higher than the front end; and the U-shaped conveying chute 32 for harvesting is inclined from left to right in cross-section, so that the white celery on the planting box 1 can tilt to one side, preventing the white celery from breaking during the conveying process; the U-shaped conveying chute 32 for harvesting forms a certain angle with the traveling direction to promote the smooth separation of the white celery from the soil.

[0099] In step one, the preparation and filling process of the nutrient soil is crucial. By quantitatively filling to the height of the reinforcing rib 103 in the long box body 101, it ensures that there is sufficient nutrient for the growth of white celery. After the pre-seedling celery 37 is laid flat on the nutrient soil, then soil is covered until the box mouth is flat to form a covering soil layer. This step not only ensures the growth environment of the celery 37 but also flattens the surface by spraying an appropriate amount of water, preparing for the smooth operation of the subsequent planting process.

[0100] The specific steps of step two are as follows:

[0101] The entire first frame 4 is connected to the tractor, and the entire planting box transplanting and seeding machine is pulled forward by the tractor. During the forward movement, the ditching blade 6 cuts into the ridge surface and moves forward with the tool to initially open two preparatory furrows that meet the requirements of the planting row spacing and the preset width and height of the planting box 1.

[0102] When the power drive chain sprocket on the tractor drives the groove forming shaft 7 to rotate, the two forming rings 8 on the groove forming shaft 7 overlap and roll in the preparatory groove initially opened by the aforementioned grooving cutter to form a planting groove that is suitable for the planting box 1 to be implanted.

[0103] At the start of the operation, a person manually inserts the first planting box 1 into the planting groove of the planting ridge 2. The second planting box 1 and other planting boxes 1 are connected end to end in the planting box conveying slide 5. As the entire planting box transplanting and seeding machine moves forward, the person manually inserts the planting box 1 into the planting groove through the corresponding planting box conveying slide 5 on the first manual operation platform. At the same time, the ridge forming shaft 7 rotates the ridge conical discs 9 at both ends to keep the ridge side maintaining the original ridge shape.

[0104] In one embodiment of this application, step three specifically involves the following steps:

[0105] The entire second frame 11 is connected to the tractor. Two pairs of conical combing heads 12 can pre-comb the celery into an upright state. The ring cutter head 162 surrounds the planting box 1, and during the forward movement, the ring cutter head 162 can cut off the celery roots on three sides of the planting box 1 and separate them from the soil.

[0106] At this time, the first plow blade 17, the second plow blade 18, and the third shaping plow blade 19 are sequentially positioned in the soil below the planting box 1, and can sequentially squeeze the soil directly below the planting box 1 to both sides to form a falling trench 3 with the same cross-sectional dimensions as the corresponding plow blade. The width of the first plow blade 17 is 1 / 3 of the width of the falling trench 3, and the height is 1 / 2 of the depth of the falling trench 3; the width of the second plow blade 18 is 2 / 3 of the width of the falling trench 3, and the height reaches the required depth of the falling trench 3; the third shaping plow blade 19 is a shaped plow blade, wider than the width of the planting box 1, with a bottom cross-section that is an inverted triangular cone suitable for the falling space of broken soil, and a height that is the required soil mound depth for white celery plus the height of the inverted triangular cone. In one embodiment, the second plow blade 18 can be a high-frequency hammer plow blade (at this time, the first plow blade 17 is cancelled), that is, the plow blade head 21 is fixed to the power output end of the high-frequency hammer, the high-frequency hammer is fixed on the second frame 11, and a hydraulic system of the implement provides power support. The high-frequency hammer is a mature product on the market and can be customized in cooperation with professional manufacturers according to the technical requirements of this invention. During operation, the high-frequency hammer plow blade cuts into the soil from below the planting box at the end of the ridge. The high-frequency vibration generated by the high-frequency hammer is transmitted to the plow blade, causing it to reciprocate in the horizontal direction. This high-frequency vibration loosens the soil, reducing resistance caused by the hardness of the soil. As the plow blade moves forward, the soil is squeezed to both sides, forming a groove with the same cross-sectional dimensions as the plow blade. The front of the plow blade is pointed, the rear is the width of the planting box, and the height is the required depth for mounding celery. The third forming plow blade 19 has a pointed head and bottom, and its rear width is one centimeter wider than the width of the planting box 1. Its height is the required depth for mounding white celery. As the machine moves forward, the third forming plow blade 19 passes through the groove opened by the high-frequency hammer plow blade, forming a groove that allows the planting box 1 to fall in, thus achieving the goal of mounding.

[0107] The planting box 1 falls into the drop trench 3 under the action of gravity. Then, under the combined action of the side pressure plates 30 on both sides and the tail clamp 15, the soil on the sides of the two ridges moves and gathers towards the middle. The soil on the ridge surface can be compacted by adjusting the weight of the counterweight on the compaction device 26 so that the gap between the top of the white celery and the soil mounds on both sides is controlled to be 3-4 cm.

[0108] In one embodiment of this application, step four specifically involves the following steps:

[0109] When it's time to start harvesting, connect the third frame 31 to the tractor, start the tractor to drive the third frame 31 forward. As the third frame 31 moves forward, the front and rear soil-breaking plow blades break the soil on the sides of the two rows of planting boxes 1. Specifically, the front plow blade 33 cuts off the upper 2 / 3 of the soil clods, and the lower part of the front plow blade 33 can break the soil and cut it off 2-3 cm below the bottom of the planting box 1 and discharge the soil towards the furrow. The rear plow blade 34 removes the remaining collapsed soil clods and discharges the soil towards the furrow, so that the celery and one side of the planting box 1 are completely exposed.

[0110] As the entire celery harvester moves forward, the ring cutter 36 surrounds the planting box 1 on three sides, thereby removing the celery roots extending outside the planting box 1 and supporting the planting box 1 forward. As it continues to move forward, the planting box 1 enters the harvesting U-shaped conveyor chute 32 and is conveyed backward, so that the planting box 1 can be harvested by separating it from the side of the undamaged soil and the planting ridge 2. Since the rear end of the harvesting U-shaped conveyor chute 32 is higher than the front end, the planting box 1 can move relatively upward, making it convenient for manual collection on the second manual operation platform.

[0111] This application presents an innovative method of planting celery in a planting box followed by transplanting and mounding. This method allows the celery to sink into the soil, achieving the purpose of mounding without the need for extensive soil removal. The equipment has a simple structure and is easy to manufacture. The width of the furrows only needs to meet the operating dimensions of a tractor, thus increasing the effective planting area and yield. Taking the one-row, two-row planting method of this invention as an example, the ridge width is 90 cm and the furrow width is 60 cm. Converted to length calculation, the planting length per acre can reach 888 meters, which is similar to the length of traditional manual planting. Compared with the aforementioned mechanized planting patent technology, which requires extensive soil removal and furrow widths of more than 1.8 meters, resulting in a reduction in effective planting area and a significant reduction in yield per acre, and the mechanical equipment has a complex structure. The first invention is single-row planting, with a planting length of about 370 meters per mu. The second invention is four-row, three-row planting, with a planting length of about 555 meters per mu. Compared with the first invention, this invention patent increases the yield per mu by about 140%, and compared with the second invention, it increases the yield per mu by about 60%. Under the same planting conditions, the significant increase in effective planting area increases the yield per mu, thereby greatly improving the planting income.

[0112] According to a 2022 survey conducted in Changzhou City on the traditional manual cultivation methods of Liyang white celery, an average of 69 workers per mu (approximately 0.16 acres) are required, with labor costs totaling 18,000 yuan, farmyard manure costs 1,550 yuan per mu, and chemical fertilizer costs 510 yuan per mu, for a total cost of 20,060 yuan per mu. However, after adopting the patented technology of this invention, only 16 workers are required per mu, with labor costs totaling approximately 4,100 yuan, farmyard manure costs 820 yuan per mu, and chemical fertilizer costs 330 yuan per mu, for a total cost of 5,250 yuan per mu. The total cost savings are 14,810 yuan per mu, greatly improving the economic benefits of cultivation.

[0113] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.

The ring cutter head (162) surrounds the planting box (1), and during the forward movement, the ring cutter head (162) can cut off the white celery roots on the three outer sides of the planting box (1) and separate them from the soil. At this time, the first plow blade (17), the second plow blade (18), and the third shaping plow blade (19) are in the soil below the planting box (1) in sequence, and can squeeze the soil directly below the planting box (1) to both sides to form a falling trench (3) with the same cross-sectional dimensions as the corresponding plow blade.

The rear plow (34) removes the remaining collapsed soil clods and discharges the soil towards the furrow, so that the white celery and one side of the planting box (1) are completely exposed. As the entire celery harvester moves forward, the ring cutter (36) surrounds the planting box (1) on three sides, thereby removing the celery roots extending outside the planting box (1) and supporting the planting box (1) as it moves forward. When it continues to move forward, the planting box (1) enters the harvesting U-shaped conveyor slide (32) and is conveyed backward, so that the planting box (1) can be harvested by separating it from the side of the undamaged soil and the planting ridge (2). Since the rear end of the harvesting U-shaped conveyor slide (32) is higher than the front end, the planting box (1) can move upward relatively, making it convenient for manual collection on the second manual operation platform.
