Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a salt-avoidance cultivation container for crops in saline-alkali land. Background Technology

[0002] Currently, existing technology discloses a salt-avoidance cultivation container for crops in saline-alkali land, including a cultivation container set in a planting hole. The cultivation container includes an isolation container set in the planting hole to isolate the outer salt-alkali layer. The isolation container contains a cultivation substrate, and the lower end of the isolation container is connected to the bottom of the planting hole, thus isolating the exogenous cultivation substrate in the isolation container from the surface salt of the saline-alkali land. By excavating a small area of ​​saline-alkali land for isolated zone planting, the amount of cultivation substrate input is effectively reduced, input costs are reduced, the water evaporation surface is reduced, and water consumption is minimized.

[0003] Using the above method, irrigation is an essential part of the daily maintenance of container cultivation. As irrigation water seeps down, the salt in the cultivation substrate will gradually be leached and deposited at the bottom of the container under the action of gravity. However, the movement of water in the soil is bidirectional. In the case of drought or strong water evaporation, the capillary action of the soil will generate a strong suction force, causing the high concentration of salt water deposited at the bottom of the container to flow back up along the soil pores and re-enter the growth area where the crop roots are located. This phenomenon of "secondary salinization" or "salinization" will seriously poison the crop roots, causing the crop to grow slowly or even die. In order to deal with this problem, the salt and water deposited at the bottom must be removed or adsorbed in a timely and effective manner.

[0004] However, most existing crop cultivation containers adopt a one-piece molded structure or have a simple bottom structure design, lacking an independent and detachable salt collection function. Even some containers with bottom trays are often connected by screws or interference fits, making disassembly very difficult. When the salt accumulated at the bottom reaches saturation or the salt-absorbing material fails and needs to be replaced, operators often have to move the entire heavy container, or even empty the soil and crops inside to reach the bottom structure. This maintenance method is not only extremely labor-intensive and inefficient, but more fatally, it is very easy to loosen the soil during handling and disassembly, damaging the fragile root system of crops and seriously affecting the survival rate and yield of crops. Therefore, the existing cultivation container structure cannot meet the needs of convenient and low-interference treatment of bottom salt in saline-alkali land cultivation.

[0005] Therefore, this utility model proposes a salt-avoidance cultivation container for crops in saline-alkali land to overcome the shortcomings of the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide a salt-avoidance cultivation container for crops in saline-alkali land, which aims to solve the problem that in some existing saline-alkali land crop cultivation containers, salt easily accumulates at the bottom and is difficult to remove, causing the salt to flow back with the water during evaporation and poison the crop roots.

[0007] To achieve the above objectives, this utility model provides a salt-avoidance cultivation container for crops in saline-alkali land, comprising: a cultivation vessel body and a salt collection chamber disposed at the bottom end of the cultivation vessel body, as well as an alignment component and a replacement mechanism connecting the cultivation vessel body and the salt collection chamber.

[0008] The replacement mechanism has a toggle-type mechanical structure that achieves rapid locking and disengagement through the lever principle.

[0009] Furthermore, the alignment component is fixedly connected to the bottom end of the cultivation device body. The alignment component includes a fixing ring and a hook plate fixed to the inner side of the fixing ring. The upper end face of the fixing ring is fixedly connected to the bottom end of the cultivation device body. The upper end face of the salt collection bin is attached to the lower end face of the fixing ring. The replacement mechanism is provided on the outer wall of the salt collection bin. The replacement mechanism includes a base plate, a buckle rod, a rotating ring, and a closing rod. The base plate is fixedly connected to the outer wall of the salt collection bin. The buckle rod is rotatably connected to the inner side of the base plate. The rotating ring is sleeved on the middle of the buckle rod. The closing rod is rotatably connected to the outer side of the rotating ring. The top end of the closing rod is engaged with the inner side of the hook plate. The buckle rod is configured to rotate around the connection point between the buckle rod and the base plate, and drive the rotating ring to rotate and the closing rod to move vertically, so that the closing rod is locked or separated from the hook plate.

[0010] Preferably, the inner wall of the cultivation device body is provided with a groove, and the top edge of the cultivation device body is provided with a splicing mechanism for connecting adjacent cultivation device bodies. The splicing mechanism includes a fixing plate, a spring plate connected to both ends of the fixing plate, and a clip provided at the end of the spring plate. The fixing plate spans across the edge above the adjacent cultivation device body, the spring plate extends downward, and the shape of the clip matches the shape of the groove, and the clip engages with the inside of the groove.

[0011] Preferably, a pull post is fixedly connected to the side of the spring plate away from the center of the fixed plate. The pull post extends horizontally in a direction away from the slot. The spring plate is elastic. When the pull post is pulled, the spring plate bends and deforms, causing the locking head to disengage from the slot.

[0012] Preferably, the spring plate and the fixed plate are set at an obtuse angle. When the fixed plate is subjected to downward pressure, the spring plate elastically bends outward until the clip head is engaged in the slot.

[0013] Preferably, the outer wall of the cultivation device is connected to a water pipe, one end of which penetrates the side wall of the cultivation device and extends into the internal cavity of the cultivation device. The water pipe is used to connect adjacent cultivation devices.

[0014] Preferably, the salt collection chamber has an independent cavity inside, and the independent cavity is filled with a salt-absorbing medium, which includes superabsorbent resin or modified vermiculite.

[0015] Preferably, there are two hook plates, which are symmetrically distributed about the central axis of the fixing ring. There are two sets of replacement mechanisms, which are symmetrically distributed on both sides of the salt collection bin and cooperate with the two hook plates respectively.

[0016] Preferably, the cultivation device body has an inverted frustum-shaped structure that is larger at the top and smaller at the bottom, and the inner diameter of the opening at the bottom of the cultivation device body is equal to the inner diameter of the fixing ring.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of salt accumulation and difficulty in removal at the bottom of existing saline-alkali land cultivation equipment. This is achieved by setting an independent salt collection chamber at the bottom of the cultivation device, using the salt-absorbing medium inside to absorb salt, and cooperating with the elbow-type quick-change mechanism consisting of a pull rod, a rotating ring, and a closing rod, which works in conjunction with the hook plate at the bottom. This solves the problems of salt accumulation at the bottom and difficulty in removal, which leads to salt evaporation and secondary backflow of salt with water, poisoning the crop roots, and the difficulty of bottom maintenance and cleaning. It achieves the technical effect of effectively physically isolating and locking salt, preventing soil salinization, and realizing quick manual disassembly and assembly of the salt collection chamber and replacement of the salt-absorbing medium. It greatly improves the efficiency of later maintenance and the survival rate of crops without disturbing the crop roots.

[0018] 2. This utility model solves the problems of loose arrangement, difficulty in quick alignment and positioning, and inability to form a stable whole to resist wind and topple when planting crops on a large scale in saline-alkali land. It is achieved by setting a splicing mechanism consisting of a fixed plate, a spring plate and a clip on the top of the cultivation container, and by using the elastic deformation of the spring plate to make the clip connect with the groove of the inner wall of the cultivation container in a snap-fit ​​manner. This achieves the technical effect of enabling rapid modular assembly of cultivation containers, with a stable connection and convenient disassembly, which is conducive to the large-scale and array-based planting and management of crops in saline-alkali land.

[0019] 3. This utility model solves the problems of uneven water and fertilizer distribution, cumbersome manual irrigation, and poor bottom water flow in existing independent cultivation containers when large-scale irrigation is carried out by setting water pipes connecting adjacent internal cavities on the side wall of the cultivation container and adopting an inverted frustum-shaped structure design that facilitates water flow. It achieves the technical effect of establishing a unified water and fertilizer circulation network among multiple containers, automatically balancing the water level and nutrient concentration in each container, and using gravity to efficiently guide saline water to converge to the bottom salt collection bin for centralized treatment.

[0023] The first embodiment of this application is as follows: Reference Figures 1 to 3 This utility model provides a salt-avoidance cultivation container for crops in saline-alkali land, which aims to solve the structural defects of existing saline-alkali land cultivation equipment, such as the easy accumulation of salt at the bottom, the difficulty in replacing the salt-absorbing medium, and the inability to effectively prevent secondary salt backflow from damaging the crop root system.

[0024] like Figure 1 and Figure 2 As shown, a salt-avoidance cultivation container for crops in saline-alkali land includes a cultivation body 1 and a salt collection chamber 31 located at the bottom of the cultivation body 1. The cultivation body 1 is used to fill soil for planting crops, and the salt collection chamber 31 is used to collect and adsorb the saline water that seeps down from the cultivation body 1.

[0025] The cultivation device 1 has an inverted frustum-shaped structure that is larger at the top and smaller at the bottom. The inverted frustum-shaped structure is conducive to the convergence of irrigation water and salt to the bottom center under the action of gravity. The inner diameter of the bottom opening of the cultivation device 1 is set to a specific size to match the lower components. The bottom of the cultivation device 1 is fixedly connected to the alignment component 32, which serves as a connection medium to achieve precise docking and fixation between the cultivation device 1 and the salt collection chamber 31.

[0026] The alignment component 32 includes a fixing ring 321 and a hook plate 322 fixed inside the fixing ring 321. The upper end face of the fixing ring 321 is fixedly connected to the bottom end face of the cultivation device body 1 by bolts or adhesive. The inner diameter of the fixing ring 321 is equal to the inner diameter of the opening at the bottom of the cultivation device body 1, ensuring that water can flow down without obstruction. There are two hook plates 322, which are symmetrically distributed about the central axis of the fixing ring 321. The hook plates 322 are fixedly connected to the inner circumferential wall of the fixing ring 321 and protrude towards the central axis of the fixing ring 321. The hook plates 322 are used to provide a force support point when locking.

[0027] The upper end face of the salt collection chamber 31 is attached to the lower end face of the fixing ring 321. The salt collection chamber 31 is detachably connected to the alignment component 32 through the replacement mechanism 3 set on the outer wall of the salt collection chamber 31. There are two sets of replacement mechanisms 3, which are symmetrically distributed on both sides of the salt collection chamber 31 and cooperate with two hook plates 322 respectively. The replacement mechanism 3 includes a base plate 33, a buckle rod 34, a rotating ring 35 and a closing rod 36.

[0028] The base plate 33 is fixedly connected to the outer wall of the salt collection bin 31. The base plate 33 serves as a support and mounting base. The bottom end of the latch rod 34 is rotatably connected to the inner side of the base plate 33 via a pin. The latch rod 34 can reciprocate around the connection point between the latch rod 34 and the base plate 33. The rotating ring 35 is movably sleeved on the middle of the latch rod 34. The rotating ring 35 can be finely adjusted or rotated on the latch rod 34. The bottom end of the closing rod 36 is rotatably connected to the outer side of the rotating ring 35. The top end of the closing rod 36 is hook-shaped and is engaged with the inner side of the hook plate 322.

[0029] In the locked state, the upper end of the latching rod 34 abuts against the outer wall of the fixing ring 321. Through the lever principle, the closing rod 36 is pulled down by the rotating ring 35, so that the closing rod 36 tightly hooks the hook plate 322, thereby pulling the salt collection tank 31 up and pressing it against the lower end face of the fixing ring 321 to achieve a sealed connection.

[0030] The salt collection chamber 31 has an independent chamber inside, which is filled with a salt-absorbing medium. The salt-absorbing medium is made of superabsorbent resin or modified vermiculite. The superabsorbent resin or modified vermiculite has a high water absorption and retention capacity and ion exchange capacity. The salt-absorbing medium is used to physically lock the salt water that seeps down from the cultivation container 1, preventing the salt from evaporating with the water and flowing back to the crop root area through capillary action. The container also includes a splicing mechanism 4 and a water pipe 2. The splicing mechanism 4 and the cultivation container 1 form a detachable snap-fit ​​connection.

[0031] The splicing mechanism 4 includes a fixed plate 41, a spring plate 42, a clip 43, and a pull column 44. The fixed plate 41 serves as the main support for connection. The fixed plate 41 is constructed as a long strip with a certain strength. The fixed plate 41 is used to span across the top edge of two adjacent cultivation containers 1. The two ends of the fixed plate 41 are respectively fixedly connected to the spring plate 42. The spring plate 42 is an elastic metal sheet or a high-strength plastic sheet. The spring plate 42 extends downward from the end of the fixed plate 41. In order to improve the durability and ease of operation of the splicing mechanism 4, the connection angle between the spring plate 42 and the fixed plate 41 is set to an obtuse angle. The obtuse angle structure makes the spring plate 42 open outward in its natural state.

[0032] A locking head 43 is fixedly connected to the inner side of the lower end of the spring plate 42. The locking head 43 has a protruding structure and is used to lock with the cultivation device body 1. A pull post 44 is fixedly connected to the outer wall of the spring plate 42. The pull post 44 is located on the side away from the locking head 43 and extends horizontally in a direction away from the center of the cultivation device body 1. The pull post 44 serves as a handle to assist in disassembly operations and cooperates with the splicing mechanism 4. A slot 45 is provided on the inner wall of the cultivation device body 1. The position of the slot 45 corresponds to the position of the locking head 43. The inner cavity shape of the slot 45 is adapted to the shape of the locking head 43 and is used to accommodate the locking head 43.

[0033] Meanwhile, the outer wall of the cultivation device 1 is connected to a water pipe 2. One end of the water pipe 2 passes through the side wall of the cultivation device 1 and extends into the internal cavity of the cultivation device 1. The water pipe 2 is used to connect the internal spaces of adjacent cultivation devices 1. Multiple cultivation devices 1 are connected in series through the water pipe 2, so that irrigation water can circulate between different cultivation devices 1, realizing the sharing of water resources and the balanced control of water level.

[0034] The working principle of this utility model is as follows: In actual use, crops are planted inside the cultivation device 1. Under the action of gravity, irrigation water and salt in the soil flow downward along the inverted frustum-shaped inner wall of the cultivation device 1. Salty water flows into the salt collection chamber 31 through the fixing ring 321 at the bottom. The salt-absorbing medium in the independent chamber of the salt collection chamber 31 adsorbs and locks the incoming salt and water, effectively preventing the salt from evaporating back to the root growth area inside the cultivation device 1 with the water.

[0035] When it is necessary to arrange salt-avoidance cultivation containers for crops in saline-alkali land on a large scale, the fixing plate 41 of the splicing mechanism 4 is placed horizontally above the top edge of two adjacent cultivation containers 1. The operator presses down on the fixing plate 41, which drives the spring plates 42 on both sides to move downward. Due to the obtuse angle structure between the spring plate 42 and the fixing plate 41 and the elasticity of the spring plate 42 itself, the spring plate 42 bends and deforms outward after contacting the edge of the cultivation container 1 until the clamping head 43 is aligned with the slot 45. The spring plate 42 uses its own elastic restoring force to drive the clamping head 43 into the slot 45, completing the physical connection of the adjacent cultivation containers 1. At the same time, the water pipe 2 is used to connect the internal cavities of the adjacent cultivation containers 1 to establish a unified water and fertilizer circulation network.

[0036] If the layout needs to be adjusted or the splicing mechanism 4 needs to be disassembled, the operator pulls the pull column 44 fixed on the spring plate 42 outward. The pull column 44 causes the spring plate 42 to bend and deform outward again, so that the clip 43 is dislodged from the slot 45. Once the locking state is released, the splicing mechanism 4 can be removed.

[0037] When the salt-absorbing medium inside the salt collection chamber 31 becomes saturated or when sediment needs to be cleaned, the operator pulls the latching rod 34 located on the outside of the salt collection chamber 31 upwards. The latching rod 34 rotates around the hinge point between the latching rod 34 and the base plate 33. The latching rod 34 drives the outer closing rod 36 upwards through the central rotating ring 35, causing the hook-shaped structure at the top of the closing rod 36 to disengage from the hook plate 322 inside the fixing ring 321. This releases the tension of the replacement mechanism 3 on the salt collection chamber 31, and the salt collection chamber 31 then separates from the fixing ring 321 and the cultivation container body 1. The operator removes the salt collection chamber 31 and replaces or cleans the salt-absorbing medium inside. After cleaning, the salt collection chamber 31 is reattached to the bottom of the fixing ring 321, and the latching rod 34 is pressed in the opposite direction, causing the closing rod 36 to hook onto the hook plate 322 again and tighten, completing the quick reset installation of the salt collection chamber 31.

[0038] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
