Description

Technical Field

[0001] The present invention relates to the technical field of white celery cultivation, and specifically refers to a method for cultivating white celery based on a planting box. Background Art

[0002] Liyang white celery, as a traditional special agricultural product with a long history in Liyang City, its cultivation history can be traced back more than 800 years. With its unique cultivation process and excellent quality, Liyang white celery obtained the registration and protection certification of agricultural product geographical indication on December 24, 2010. Its cultivation feature is that when the water celery grows to about 30 to 35 centimeters through dry cultivation, artificial deep soil piling treatment is carried out, enabling the celery stem to continue growing and turning white in a soil environment without light and sealed, thus getting the name "white celery". White celery is known as a unique delicacy among the Jiangnan gourmet dishes with its jade-white stem, golden celery buds, and unique flavor of being slightly sweet, not greasy, crispy and refreshing.

[0003] However, the traditional cultivation method of Liyang white celery faces many challenges. Around the White Dew every year, growers need to pre-cultivate long strip-shaped seed celery and plant it horizontally in strips on the ridges. When the celery grows to an appropriate height, a cumbersome manual soil piling operation is required. In this process, wooden boards are used as templates, and multiple people cooperate to fill and compact the soil, with extremely high labor intensity and low operation efficiency. Even more difficult is that harvesting white celery needs to be carried out in the coldest months of winter. Growers need to wash the white celery by hand in icy water, which not only increases the labor intensity but also limits the production efficiency. Therefore, the cost of manual soil piling and harvesting links under the traditional cultivation method accounts for a high proportion, and the working environment is harsh, resulting in young people generally being reluctant to engage in this industry, affecting the sustainable development of the Liyang white celery industry.

[0004] In response to the deficiencies of the traditional cultivation method, preliminary exploration has been carried out on existing mechanized cultivation technologies. For example, the white celery seed metering machine with the patent number ZL201610099159.2, although it realizes the mechanization of multiple processes such as fertilization, ridge formation, ditch opening, seed metering, and soil covering, its seed metering process is different from the method of this invention patent, and the planting efficiency is low and the planting quality is poor, unable to achieve the goal of factory cultivation.

[0005] In addition, the special soil piling machine for white celery with the patent number ZL201510801031.1 and a four-ridge three-row special soil piling machine for white celery with the application number 2023107832582, although they adopt the mechanical spiral soil taking and piling technology, still have many deficiencies. Such as large soil taking amount, large reserved area required for the ridge ditch, resulting in a reduction in the effective planting area and a decrease in yield; complex mechanism, high requirements for equipment; low soil piling efficiency, poor sealing effect, affecting the quality and appearance of white celery; and unable to achieve the goal of mechanized continuous and rapid harvesting of white celery. Therefore, existing mechanized cultivation technologies still need to be further improved and perfected. Summary of the Invention

The two conical combing heads in the same group present a left-right symmetric flared oblique cone surface shape, and their forward direction also uses an oblique cone surface; the width of the flared opening 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 oblique cone surface of the conical combing head gradually rises to the height of the front clamp and finally smoothly transitions to the front clamp.

[0024] The ditch-opening mechanism includes a separating ring knife, a first plow knife, a second plow knife, and a third forming plow knife arranged on the second frame in sequence from front to back; the separating ring knife includes a ring knife handle and a ring knife head arranged at the lower end of the ring knife handle. The ring knife handle is two ring knife steel plates fixed to the second frame, and the inner cavity of the ring knife handle is used to fix the front clamp; the ring knife head is U-shaped, and one end is a knife-edge structure.

[0025] The first plow knife, the second plow knife, and the third forming plow knife are all composed of a plow knife head and a plow knife handle. The plow knife handle is two plow knife steel plates arranged on the second frame. The inner cavity between the two plow knife steel plates is used to fix the two front clamps so that a first channel capable of passing through the white celery in an upright state is formed between the two front clamps, and a second channel for the planting box to pass through is also formed between the upper end of the plow knife head and the two plow knife 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 forming 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 forming 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-side-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 ditching mechanism;

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

[0030] The ridge closing and compacting 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 fixing 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 fixing 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 horizontal 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 conveying chutes for picking-up and putting-down are respectively installed behind the corresponding circular cutting knife devices. The rear end of the U-shaped conveying chute for picking-up and putting-down is higher than the front end; and the U-shaped conveying chute for picking-up and putting-down is inclined with the left side higher than the right side in the cross-section, so that the white celery on the planting box can tilt to one side, preventing the white celery from breaking during the conveying process; the U-shaped conveying chute for picking-up and putting-down forms a certain angle with the traveling direction to promote the smooth separation of the planting box from the soil.

[0035] Further, the specific steps of the first step are as follows:

[0036] Quantitatively fill the prepared nutrient soil with a certain viscosity to the height of the reinforcing ribs in the long strip box body, and lay the pre-seedling celery flat on the nutrient soil according to the quantity requirements;

[0037] Then cover the nutrient soil on the celery until it is flat with the mouth of the long strip box body to form a covering soil layer, and then spray an appropriate amount of water on the covering soil layer to flatten its surface.

[0038] Further, the specific steps of the second step are as follows:

[0039] Connect the entire first frame to the tractor, and the entire planting box transplanting and seeding machine is pulled forward by the tractor. During the forward movement, the ditch-opening and row-cutting knives cut into the ridge surface and initially open two preparatory ditches that meet the requirements of the planting row spacing and the preset width and height of the planting box as the implement moves forward;

[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 ditches initially opened by the ditch-opening and row-cutting knives to form planting grooves that meet the implantation requirements of the planting box;

[0041] At the start of the operation, someone manually implants the first planting box into the planting groove of the planting ridge, and the second planting box and other planting boxes are connected end to end in sequence in the planting box conveying chute. As the entire planting box transplanting and seeding machine moves forward, someone manually implants the planting boxes into the planting grooves through the corresponding planting box conveying chutes on the first manual operation platform. At the same time, the ridge-forming conical discs at both ends of the groove forming shaft rotate to keep the side of the ridge in its original shape.

[0042] Further, the specific steps of the third step are as follows:

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

[0044] At this time, the first plow blade, the second plow blade, and the third forming plow blade are all in the soil below the planting box, and can successively squeeze the soil directly below the planting box to both sides to form a falling groove with the same cross-sectional size as the corresponding plow blade. Among them, the width dimension of the first plow blade is 1 / 3 of the width of the falling groove, and the height is 1 / 2 of the depth of the falling groove; the width dimension of the second plow blade is 2 / 3 of the width of the falling groove, and the height reaches the required depth of the falling groove; the third forming plow blade is a forming plow blade, the width is wider than the width of the planting box, the bottom cross-section is an inverted triangular cone suitable for the falling space of broken soil, and the height is the depth of soil heaping required for white celery plus the height of the inverted triangular cone.

[0045] Under the action of gravity, the planting box falls into the falling groove. Subsequently, by adjusting the distance between the tails of the side pressing plates on both sides of the ridge-forming and compacting device, the soil on both sides of the two ridges is displaced and gathered towards the middle direction, and the weight on the ridge-forming and compacting device can be adjusted to compact the soil on the ridge surface so that the width dimension of the gap between the upper part of the white celery and the soil heaped on both sides is controlled within 3 - 4 centimeters.

[0046] Furthermore, the specific steps of the fourth step are as follows:

[0047] When it comes to harvesting, connect the third rack to the tractor and start the tractor to drive the third rack forward. During the forward movement of the third rack, the front soil-breaking plow blade group and the rear soil-breaking plow blade group respectively break the soil on the sides of the two rows of planting boxes. Specifically, the front plow blade cuts the upper 2 / 3 of the soil block position, and the lower part of the front plow blade can break the soil at a position 2 - 3 centimeters below the bottom of the planting box and discharge the soil towards the furrow direction. The rear plow blade clears the remaining collapsed soil blocks and discharges the soil towards the furrow direction, so that one side of the white celery and the planting box is completely exposed.

[0048] When the entire white celery harvester moves forward, the circumferential cutting knife surrounds the planting box on three sides, so that the white celery roots extending outside the planting box can be removed and the planting box can be supported to move forward. When continuing to move forward, the planting box enters the U-shaped conveying chute for harvesting and is conveyed backward, so that the planting box can be separated from the unbroken soil side and the planting ridge surface for harvesting. Since the rear end of the U-shaped conveying chute for harvesting is higher than the front end, the planting box can move relatively upward, which is convenient for the workers on the second manual operation platform to collect.

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

[0050] (1) By using the planting box with long waist holes, the present invention can realize factory-style seed sowing and planting, improve the planting efficiency and quality. The lap setting at both ends of the planting box enables the planting boxes to be connected end to end to form continuous planting rows, which is convenient for mechanized operation.

[0051] (2) By using a combination of mechanized devices such as a rotary tiller and ridger, a transplanting and seeding machine, a transplanting and soil banking machine, and a white celery harvesting machine, the present invention realizes the full mechanized operation from rotary tilling and ridging, seeding, transplanting, soil banking to harvesting, greatly reducing manual labor and labor intensity and improving operation efficiency.

[0052] (3) Through the precise control of the pre-ditching mechanism and the groove forming device, the present invention ensures that the width and depth of the groove meet the requirements of the planting box. The rolling and compaction device ensures that the planting box can be stably placed on the planting ridge after being transplanted into the groove, avoiding poor plant growth caused by soil loosening. The setting of the anti-collapse baffle of the transplanting and soil banking machine ensures that the soil on both sides of the groove will not collapse. The combined use of the ridge closing and compaction device and the tail end clamping plate closes the soil on both sides towards the middle of the ridge and compacts the ridge surface, so that the gap between the celery falling into the groove and the soil banking on both sides meets the requirements to achieve the best sealing effect, enabling the celery to be fully whitened during growth in the groove, ensuring the whitening effect of the white celery, and isolating the celery from the soil on both sides by the tail end clamping plate to prevent the soil from squeezing into the internal void area of the celery and affecting the appearance quality of the white celery and subsequent harvesting operations.

[0053] (4) Compared with the traditional white celery planting method that requires a large amount of manual labor for soil banking and harvesting, the use of the planting box and mechanized devices in the present invention significantly reduces the labor demand and labor cost. The front and rear soil-breaking plow blades and the harvesting circular cutting blade provided on the white celery harvesting machine are used to harvest the planting box to achieve the purpose of harvesting white celery, enabling the white celery to be harvested intact in a short time, reducing the harvesting time, and the mechanized operation also avoids the heavy physical labor in the traditional method during the cold season, improving the working environment of farmers.

[0054] (5) Compared with the existing mechanized technology planting method, the present invention reduces the reserved area of the furrow, ensures the maximization of the effective planting area per mu, significantly increases the yield per mu and thus increases the income.

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

[0079] The specific implementation manners of the present invention will be further described below with reference to the accompanying drawings. Among them, the same components are denoted by the same reference numerals.

[0080] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0081] In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0082] The present invention relates to a method for planting white celery based on a planting box, which specifically includes the following steps:

[0083] Step 1: First, seed the seed celery 37 in the planting box 1 with nutrient soil, and then transplant it to the planting ridge 2 for seeding;

[0084] Step 2: Use a planting box transplanting and metering machine to move the planting box 1 with the planted celeriac 37 in Step 1 to the planting ridge 2 for metering. The planting ridge 2 is a one-row-two-line planting ridge. In this embodiment, the height of the planting ridge 2 is 30 cm, the width of the ridge top is 50 cm, the width of the ridge bottom is 90 cm, the width of the ridge ditch is 60 cm, the row spacing is 20 cm, the side row spacing is 15 cm, and the converted planting length per mu is 888 m.

[0085] Step 3: When earthing up is required after the white celery grows up, use a transplanting earthing-up machine to open a falling groove 3 under the planting box 1 so that it falls into the falling groove 3 to achieve the purpose of earthing up.

[0086] Step 4: Use a white celery harvesting machine to take out the planted box 1 with earthing up in the planting ridge 2 together with the white celery.

[0087] In the process of planting white celery using the planting box 1, the design of the planting box 1 is crucial. As shown in the Figure 1 - attached Figure 3 figure. In this embodiment, the planting box 1 adopts the form of a long strip box body 101, with specific dimensions of 70 cm in length, 7 cm in width, and 10 cm in height. Such a design is not only convenient for operation but also can provide sufficient growth space for white celery. Long waist holes 102 are provided at the bottom and both sides of the long strip box body 101. This design aims to promote the growth of the white celery roots outside the box body, enhancing the stability and absorption capacity of the roots. In addition, a number of reinforcing ribs 103 are provided at the bottom of the inner cavity of the long strip box body 101 to enhance the structural strength of the entire long strip box body 101 and can be used as the depth position line during the metering of celeriac seeds. To facilitate the continuity of the planting box 1 for mechanized operations, snap buckles 104 and snap-in interfaces matching the snap buckles 104 are respectively provided at both ends of the long strip box body 101, so that multiple planting boxes 1 can be stably connected together.

[0088] As shown in the Figure 4 - attached Figure 8As shown in the figure, in order to achieve efficient transplanting and seeding of the planting box 1, this embodiment provides a planting box transplanting and seeding machine. The specific composition of the planting box transplanting and seeding machine includes: a first frame 4, a pre-trenching mechanism, a groove forming device, a planting box conveying chute 5, a rolling and compressing device, a planting box stacking platform, and a first manual operation platform. The first frame 4 is connected to a tractor to provide power for the entire device. The pre-trenching mechanism includes two trench-opening and seeding knives 6 oppositely arranged at the front end of the first frame 4, which can initially open a preparatory trench. The groove forming device includes a groove forming shaft 7 rotatably installed on the first frame 4. Two forming rings 8 are provided on the groove forming shaft 7, and the positions of the two forming rings 8 correspond to the positions of the two trench-opening and seeding knives 6 one by one. Through the forming rings 8, planting grooves suitable for implanting the planting box 1 can be rolled and formed. Both ends of the groove forming shaft 7 are equipped with ridging conical discs 9, and a sprocket cooperating with the tractor transmission system is also installed at one end of the groove forming shaft 7. Two planting box conveying chutes 5 are designed and are both U-shaped structural members. Their upper ends are fixed to the upper part of the first frame 4, and their lower ends are installed at the lower part of the first frame 4. After installation, the center lines of the two planting box conveying chutes 5 coincide with the center line of the preparatory trench formed by the forming rings 8 on the ridge surface, so as to ensure that the planting box 1 can smoothly slide from the planting box conveying chute into the planting groove. The planting box stacking platform is arranged in the upper area of the first frame 4, and the first manual operation platform is located in the lower area of the first frame 4; the rolling and compressing device is composed of a rolling shaft 10 rotatably installed at the rear end of the first frame 4. When the entire planting box transplanting and seeding machine moves forward, the bottom surface of the rolling shaft 10 presses on the ridge surface, so that two rows of planting boxes 1 are ensured to be on a plane through the rolling of the rolling shaft 10, to ensure the smooth completion of subsequent processes, and to make the planting box 1 adhere well to the soil on the ridge surface, ensuring that the celery in the planting box 1 has a good growth environment.

[0089] As the white celery grows, the operation of piling up soil becomes particularly important. As shown in the attached Figure 9 - attached Figure 19 figure, the transplanting and soil piling machine provided in this embodiment includes a second frame 11, two groups of combing mechanisms, two groups of trench-opening mechanisms, two anti-side-collapse baffles 20, and a ridge closing and compressing device.

[0090] The second frame 11 serves as the core support structure of the entire machine and is firmly connected to the tractor, ensuring stability and flexibility during operation. The combing mechanism includes two pairs of conical combing heads 12 (one pair of conical combing heads 12 consists of two conical combing heads symmetrically installed on the left and right) mounted on the second frame 11, two groups of front clamps 13, two groups of rear clamps 14, and two groups of tail-end clamps 15; the ends of the two pairs of conical combing heads 12 are fixed to the front of the second frame 11 and are transitionally connected to the corresponding front clamps 13; the two conical combing heads in the same group straddle the roots of the ridge celery on both sides, the distance between the cone heads of the two conical combing heads in the same group is 12 cm, and the distance between the cone tails is 6 cm. The two conical combing heads in the same group present a flared oblique cone surface shape that is symmetric left and right, and its forward direction also uses an oblique cone surface; the width of the flared opening formed by the two conical combing heads 12 gradually narrows from front to back until it matches the width of the two front clamps 13; at the same time, in the height direction, the oblique cone surface of the conical combing head 12 gradually rises to the height of the front clamp 13 and finally smoothly transitions to the front clamp 13. The design of the combing mechanism is particularly ingenious. The two pairs of conical combing heads 12 and their supporting clamp combinations can effectively comb the celery to make it stand upright, avoid entanglement, and can fall smoothly into the trench to obtain a good soil covering effect, thus ensuring the internal quality and appearance quality of the celery, reflecting the humanized design concept.

[0091] The ditching mechanism includes a separating ring knife 16, a first plow knife 17, a second plow knife 18, and a third forming plow knife 19 that are sequentially arranged on the second frame 11 from front to back; the separating ring knife 16 includes a ring knife handle 161 and a ring knife head 162 provided at the lower end of the ring knife handle 161. The ring knife handle 161 is two ring knife steel plates fixed to the second frame 11, and the inner cavity of the ring knife handle 161 is used to fix the front clamp 13; the ring knife head 162 is U-shaped, and one end is a knife-edge structure, which can quickly and accurately cut the external roots of the planting box 1, separating the planting box 1 from the soil completely, preparing for it to fall smoothly after ditching.

[0092] The first plow knife 17, the second plow knife 18, and the third forming plow knife 19 are all composed of a plow knife head 21 and a plow knife handle 22, and the first plow knife 17, the second plow knife 18, and the third forming plow knife 19 are designed in a progressive manner, reducing the difficulty of groove forming and ensuring the quality of the groove opened by the third forming plow knife 19. The plow knife handle 22 is two plow knife steel plates arranged on the second frame 11. The inner cavity between the two plow knife steel plates is used to fix the two front clamps 13 so that a first channel 23 that can pass the celery in an upright state is formed between the two front clamps 13, and a second channel 24 for the planting box 1 to pass through is also formed between the upper end of the plow knife head 21 and the two plow knife steel plates on both sides; the combination of the plow knife head 21 and the plow knife steel plates not only ensures the structural stability but also reserves enough space for the passage of the celery and the planting box 1.

[0093] The upper front end of the rear splint 14 is connected to the plow handle 22 of the third forming plow blade 19, and its lower part extends into and is connected to the rear end of the plow blade head 21 of the third forming plow blade 19. The upper rear part of the rear splint 14 is connected to the second frame 11, and the front end of the tail-end splint 15 is integrally connected to the rear end of the rear splint 14. The tail-end splint 15 can move forward following the rear splint 14, with a height 2 - 3 centimeters higher than the ridge surface and the bottom flush with the lower end of the aforementioned rear splint 14. Thus, a passage through which white celery can pass is formed from the conical combing head 12, the front splint 13, the rear splint 14 to the tail-end splint 15, enabling the white celery to fall smoothly into the trench in an upright state and achieving a good soil covering effect, thereby ensuring the internal and external quality of the white celery.

[0094] Two anti-collapse baffles 20 are respectively installed on both sides of the second frame 11. The anti-collapse baffles 20 are provided in consideration of 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, ensuring the continuity and stability of the operation.

[0095] In an embodiment of the present application, the ridge closing and compaction device includes a hinged tie rod mechanism and a ridge closing and compaction member; 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 far from the second frame 11 are respectively hinged to both sides of the upper end of the ridge closing and compaction member; the design of the hinged tie rod mechanism ensures that the ridge closing and compaction member can move flexibly in the vertical direction, effectively controlling the compaction degree of the ridge surface.

[0096] The ridge closing and compaction member includes a middle steel plate 26 and side steel plates 27 respectively provided on both sides of the middle steel plate 26. There are through grooves 28 coinciding with the center line of the tail-end splint 15 left between the middle steel plate 26 and the side steel plates 27 on both sides, and the sides of the two tail-end splints 15 in the same group are respectively clamped on both sides of the through grooves 28. The upper ends of the two through grooves 28 connect the middle steel plate 26 and the side steel plates 27 on both sides into one body through U-shaped members 29. And side pressing plates 30 with the same angle as the side of the planting ridge 2 are provided at the lower ends of the side steel plates 27 on both sides. Fixing bolts and adjusting bolts are respectively provided at the front and rear ends of the side steel plates 27, and circular holes and long waist arc-shaped holes are respectively provided at the front and rear ends of the side pressing plates 30. The fixing bolts and the adjusting bolts are respectively placed in the circular holes and the long waist arc-shaped holes to adjust the opening size between the side pressing plates 30 on both sides, thereby adjusting the distance between the rear ends of the side pressing plates 30 on both sides 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 sealing environment for the subsequent blanching growth of the white celery.

[0097] As shown in the attached Figure 20 - attached 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 circumcision knife devices, two U-shaped conveying chutes 32 for harvesting, and a second manual operation platform disposed 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 bearing each functional component, 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 circumcision knife device is installed behind the corresponding soil-breaking plow blade group to ensure the coherence of the soil-breaking and circumcision actions. The mounting plate 35 serves as the support platform for the circumcision knife 36 and is connected to the third frame 31 through precise design, ensuring the stability and accuracy of the circumcision knife 36 during operation. The circumcision knife 36 with an "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 circumcision knife devices, and 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 strip 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 to the level of the box mouth 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, making preparations for the subsequent planting process to operate smoothly.

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

[0101] Connect the entire first rack 4 to the tractor, and the entire planting box transplanting and seeding machine is pulled forward by the tractor. During the forward movement, the ditching and rowing knife 6 cuts into the ridge surface and initially opens two preparatory ditches that meet the requirements of the planting row spacing and the preset width and height of the planting box 1 as the implement moves forward.

[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 ditches initially opened by the above-mentioned ditching and rowing knife to form planting grooves that meet the implantation of the planting box 1.

[0103] At the start of the operation, a worker implants 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 sequence in the planting box conveying chute 5. As the entire planting box transplanting and seeding machine moves forward, the worker on the first manual operation platform implants the planting boxes 1 into the planting grooves in sequence through the corresponding planting box conveying chutes 5. At the same time, the ridge-forming conical discs 9 at both ends of the groove forming shaft 7 rotate to keep the side of the ridge in its original shape.

[0104] In an embodiment of the present application, the specific steps of step three are as follows:

[0105] Connect the entire second rack 11 to the tractor. The two pairs of conical carding heads 12 can pre-card the white celery into an upright state. The ring knife head 162 surrounds the planting box 1, and during the forward movement, the ring knife head 162 can cut off the white celery roots on three sides of the planting box 1 and separate it from the soil.

[0106] At this time, the first plow blade 17, the second plow blade 18, and the third forming plow blade 19 are successively in the soil below the planting box 1, and can successively squeeze the soil directly below the planting box 1 to both sides to form a falling groove 3 with the same cross-sectional size as the corresponding plow blade. Among them, the width dimension of the first plow blade 17 is 1 / 3 of the width of the falling groove 3, and the height is 1 / 2 of the depth of the falling groove 3; the width dimension of the second plow blade 18 is 2 / 3 of the width of the falling groove 3, and the height reaches the required depth of the falling groove 3; the third forming plow blade 19 is a forming plow blade, the width is wider than the width of the planting box 1, the bottom cross-section is an inverted triangular cone suitable for the soil falling space, and the height is the required soil banking depth for white celery plus the height of the inverted triangular cone; in one embodiment, the second plow blade 18 can adopt a high-frequency hammer plow blade (the first plow blade 17 is cancelled at this time), that is, the plow blade head 21 is fixed at the power output end of the high-frequency hammer, the high-frequency hammer is fixed on the second frame 11, and the power is provided by the hydraulic system of the agricultural implement. 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 technology. During operation, the high-frequency hammer plow blade cuts into the soil 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 the plow blade to generate reciprocating high-frequency vibration in the horizontal direction, making the soil loosen due to the high-frequency vibration to reduce the resistance caused by the hardness of the soil. As the plow blade moves forward, the soil is squeezed to both sides to form a groove with the same cross-sectional size as the plow blade. The front part of the plow blade is in the shape of a sharp knife, and the rear part is the width dimension of the planting box, and the height is the required size for the soil banking depth of celery; the plow blade head and the bottom of the third forming plow blade 19 are both in the shape of a sharp cone, the rear width is one centimeter wider than the width of the planting box 1, and the height meets the requirements for the soil banking of white celery. As the agricultural implement moves forward, the third forming plow blade 19 passes through the groove opened by the high-frequency hammer plow blade described above, and a groove that meets the falling of the planting box 1 is formed at the passing place to achieve the goal of soil banking.

[0107] Under the action of gravity, the planting box 1 falls into the falling groove 3. Subsequently, under the combined action of the side pressing plates 30 on both sides and the tail clamping plate 15, the soil on both sides of the two ridges moves and converges towards the middle direction, and the weight of the counterweight on the closing and compressing device 26 can be adjusted to compact the soil on the ridge surface so that the width dimension of the gap between the upper part of the white celery and the soil banked on both sides is controlled within 3-4 centimeters.

[0108] In one embodiment of the present application, the specific steps of step four are as follows:

[0109] When it comes to harvesting, connect the third frame 31 to the tractor and start the tractor to drive the third frame 31 forward. During the forward movement of the third frame 31, the front soil-breaking plow blade group and the rear soil-breaking plow blade group respectively break the soil on the sides of the two rows of planting boxes 1. Specifically, the front plow blade 33 cuts the upper 2 / 3 of the soil block, and the lower part of the front plow blade 33 can break the soil at a position 2-3 centimeters below the bottom of the planting box 1 and discharge the soil towards the ridge ditch. The rear plow blade 34 clears the remaining collapsed soil blocks and discharges the soil towards the ridge ditch, so that one side of the white celery and the planting box 1 is completely exposed;

[0110] When the entire white celery harvesting machine moves forward, the circumferential cutting knife 36 surrounds the planting box 1 on three sides, so that it can remove the white celery roots extending outside the planting box 1 and support the planting box 1 to move forward. When continuing to move forward, the planting box 1 enters the U-shaped conveying chute 32 for rearward conveying, so that the planting box 1 can be harvested by disengaging from the unbroken soil side and the surface of the planting ridge 2. Since the rear end of the U-shaped conveying chute 32 is higher than the front end, the planting box 1 can move upward relatively, facilitating the collection by the workers on the second manual operation platform.

[0111] This application adopts an innovative method of transplanting and covering soil after seeding in the planting box. The celery moves downward and sinks into the soil to achieve the purpose of covering soil, without the need to take a large amount of soil. The machine structure is simple and easy to manufacture. The width dimension of the ridge ditch only needs to meet the operation dimension of the tractor, which improves the effective planting area and increases the yield. Taking the planting of two rows in one ridge of the technical solution of the present invention as an example, the ridge width is 90 cm, and the reserved width of the ridge ditch is 60 cm. Calculated in terms of length, the planting length per mu can reach 888 meters, which is similar to the traditional manual planting length. Compared with the mechanized planting patent technology in the foregoing technical background, it needs to take a large amount of soil and the reserved ridge ditch width is more than 1.8 meters, resulting in a reduction in the effective planting area and a significant reduction in the mu yield, and the mechanical equipment structure is complex. The first invention is single-row planting, with a planting length of about 370 meters per mu. The second invention is three-row planting in four ridges, with a planting length of about 555 meters per mu. Compared with the first invention, the mu yield of this invention increases by about 140%. Compared with the second invention, the mu yield increases by about 60%. Under the same planting conditions, the significant increase in the effective planting area increases the mu yield, thus greatly improving the planting income.

[0112] According to the investigation and statistics of the traditional manual planting method of Liyang white celery in Changzhou in 2022, 69 man-hours are required per mu, with a labor cost of 18,000 yuan, a farmyard manure cost of 1,550 yuan per mu, and a chemical fertilizer cost of 510 yuan per mu. The total cost per mu of the three items is 20,060 yuan. After adopting the technology of this invention patent, only 16 man-hours are required per mu, with a labor cost of about 4,100 yuan, a farmyard manure cost of 820 yuan per mu, and a chemical fertilizer cost of 330 yuan per mu. The total cost per mu of the three items is 5,250 yuan. The above total cost savings per mu reach 14,810 yuan, greatly improving the planting economic benefits.

[0113] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative work, a structural manner and an embodiment similar to the technical solution without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.

The method for planting white celery based on a planting box according to claim 6, characterized in that: The specific steps of step 4 are: When it is time to start and collect, the third frame (31) is connected to the tractor, and the tractor is started to drive the third frame (31) forward. During the forward movement of the third frame (31), the front soil-breaking coulter group and the rear soil-breaking coulter group respectively break the soil on the sides of the two rows of planting boxes (1). Specifically, the front coulter (33) cuts off the upper 2 / 3 of the soil block position, and the lower part of the front coulter (33) can break the soil and remove the soil 2 to 3 centimeters below the bottom of the planting box (1) and discharge the soil in the direction of the ridge ditch. The rear coulter (34) removes the remaining collapsed soil blocks and discharges the soil in the direction of the ridge ditch, so that the white celery and one side of the planting box (1) are completely exposed; When the entire white celery harvester moves forward, the circumcision knife (36) embraces the planting box (1) on three sides, thereby being able to remove the white celery roots extending outside the planting box (1) and to support the planting box (1) to move forward. When continuing to move forward, the planting box (1) enters the collecting U-shaped conveying slide (32) and is conveyed backward, so that the planting box (1) can be separated from the unbroken soil side and the planting ridge (2) surface and collected. Since the rear end of the collecting U-shaped conveying slide (32) is higher than the front end, the planting box (1) can be relatively moved upward, which is convenient for manual collection on the second manual operation platform.
