Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and in particular to a seedling device. Background Technology

[0002] With the rapid development of modern facility agriculture, factory-style tray seedling technology has been widely used in the propagation of seedlings of vegetables, flowers and medicinal materials due to its advantages such as high sowing efficiency, fast seedling growth, and convenient transportation and management. Traditional seedling devices usually use standardized plastic trays or seedling cups, whose structure consists of several arrays of independent holes. Individual plants are cultivated by filling the holes with nutrient substrate. This method can significantly improve seedling density and land utilization, and is conducive to the standardization and automation of management links such as irrigation and fertilization.

[0003] However, existing seedling raising devices still have significant technical defects in practical applications. First, because the inner walls of traditional seedling holes are mostly smooth, closed curved or flat surfaces, plant roots, which are geotropic and hydrotropic, cannot stop growing once they touch the inner wall. They often slide along the smooth inner wall and extend downwards in a spiral, eventually forming a dense, coiled root ball at the bottom of the seedling hole. This mechanical root coiling phenomenon not only inhibits the differentiation and development of effective fibrous roots but also makes it difficult for the roots to quickly extend into the surrounding new soil after transplanting, significantly prolonging the seedling recovery period and thus affecting the later yield of the crop. Second, as the roots grow, there will be significant friction and adsorption between the root ball and the inner wall of the seedling hole, making it extremely difficult to remove the seedling. Operators often need to pull the seedling stem with force, which can easily cause stem breakage, root damage, or loosening and breaking of the root ball. This not only greatly increases the labor intensity but also directly reduces the survival rate and work efficiency after transplanting. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the prior art and to propose a seedling raising device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A seedling raising device includes a mounting frame, a seedling tray inside the mounting frame, seedling holes fixedly installed inside the seedling tray, a drainage hole at the bottom end of each seedling hole, a root guide rib fixedly installed on the inner wall of each seedling hole, a guide groove formed at the middle of the end of the root guide rib away from the inner wall of the seedling hole, a serrated strip fixedly installed on the inner wall of the guide groove, and a ventilation slit formed on the inner wall of each seedling hole. The device also includes:

[0007] Ventilation slot, the ventilation slot being formed on the side wall at the bottom of the mounting frame;

[0008] The seedling apex needle is fixedly installed on the bottom wall of the mounting frame.

[0009] Preferably, the saw-tooth racks are arranged on the surface of the guide groove at equal intervals, and the ventilation slits penetrate through the inner wall of the cavity hole.

[0010] Preferably, the inner wall of the mounting frame is provided with two sets of limiting grooves arranged in the vertical direction, a support bar is slidably connected inside the mounting frame, one end of the support bar close to the inner wall of the mounting frame is provided with an inner groove, a sliding rod is slidably connected inside the support bar, one end of the sliding rod close to the inside of the inner groove is fixedly connected with a clamping block, and a tension spring is sleeved on the surface of the sliding rod.

[0011] Preferably, the inner groove is in a shape of "hui", and the sliding rod penetrates through the inner groove and extends to the outside of the support bar.

[0012] Preferably, the clamping block is adapted and clamped with the limiting groove, one end of the tension spring is fixedly connected to the surface of the clamping block, and the other end is fixedly connected to the inner wall of the inner groove.

[0013] Preferably, a support rod is fixedly connected to the surface of the support bar, the support rod is in a shape of "jing", and the support rod is fittingly supported at the bottom of the cavity hole.

[0014] Preferably, the top of the mounting frame is provided with a vertical groove, the bottom wall of the vertical groove is fixedly provided with a telescopic rod, the surface of the telescopic rod is sleeved with a pressure spring, the top end of the telescopic rod is fixedly provided with a connecting sleeve, and the inner wall of the connecting sleeve is inserted with an inserting rod.

[0015] Preferably, the bottom end of the pressure spring is fixedly installed on the bottom wall of the vertical groove, the top end of the pressure spring is fixedly installed at the bottom of the connecting sleeve, the two ends of the inserting rod are respectively inserted into the inner walls of the left and right connecting sleeves, and the inserting rod is located directly above the support rod.

[0016] Compared with the prior art, the present utility model provides a seedling raising device, which has the following beneficial effects:

[0017] 1. According to the seedling raising device, by arranging the root guide ribs and the guide grooves with the saw-tooth racks on the surface on the inner wall of the cavity hole, continuous physical blocking points are formed, the frictional resistance of roots growing downward is increased, which not only prevents the roots from rushing to the bottom quickly and smoothly, but also effectively prevents the roots from crossing the ribs to wind transversely and spirally, so as to avoid the root coiling phenomenon, thereby inducing the roots to differentiate more lateral roots in the middle of growth and improving the development condition of seedling raising.

[0018] 2. This seedling device, through the ventilation seams on the inner wall of the seedling holes and the ventilation grooves at the bottom of the mounting frame, forms an excellent air convection system. The root tips come into contact with the air and dry naturally due to air pruning, inhibiting excessive elongation of the main root and promoting explosive growth of fibrous roots. In addition, the height of the seedling tray can be adjusted by the cooperation of the sliding rod and the locking block, so that the position is higher in the early stage of seedling cultivation to maintain high humidity, and lowered to the side of the ventilation groove in the later stage to enhance ventilation, meeting the needs of different growth stages.

[0019] 3. This seedling raising device uses a seedling-topping needle fixed to the bottom wall in conjunction with a liftable support bar. The support bar can be unlocked to lower the seedling tray, and the seedling-topping needle passes through the drainage hole to push the root-soil combination upward, achieving automatic separation from the inner wall. With the help of the top insertion rod, the seedling tray is kept stable. Operators can remove seedlings without having to pull the stems forcefully, effectively solving the problems of stem breakage, root damage, or loose soil ball caused by traditional seedling removal.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-6 A seedling raising device includes a mounting frame 1. A seedling tray 21 is disposed inside the mounting frame 1. Seedling holes 22 are fixedly installed inside the seedling tray 21. Drainage holes 23 are provided at the bottom end of the seedling holes 22. Root guide ribs 24 are fixedly installed on the inner wall of the seedling holes 22. To enhance the root guiding effect and facilitate demolding, the cross-section of the root guide ribs 24 is preferably trapezoidal or semi-circular, and extends along the vertical direction of the seedling holes 22. A guide groove 25 is provided at the middle of the end of the root guide ribs 24 away from the inner wall of the seedling holes 22. A serrated strip 26 is fixedly installed on the inner wall of the guide groove 25. A ventilation slit 27 is provided on the inner wall of the seedling holes 22. In actual production, the ventilation slit 27 can also be designed to be vertical. The structure includes several discontinuous short slits arranged in a directional array to ensure the overall structural strength of the holes 22. Sawtooth strips 26 are evenly spaced on the surface of the guide groove 25. Ventilation slits 27 penetrate the inner wall of the holes 22. The structure also includes: ventilation grooves 31, which are opened on the side wall at the bottom of the mounting frame 1; and seedling pins 46, which are fixedly installed on the bottom wall of the mounting frame 1. The number and position of the seedling pins 46 correspond one-to-one with the number and position of the holes 22. The top of the seedling pins 46 is designed with an arc or spherical surface to prevent damage to the plant roots when seedling is seedling. The outer diameter of the seedling pins 46 is smaller than the diameter of the drainage hole 23 to ensure that they can pass smoothly through the drainage hole 23 and lift the root ball completely.

[0030] Reference Figures 3-5The inner wall of the mounting frame 1 has limiting grooves 32, with two sets of limiting grooves 32 arranged vertically. In another variation, multiple sets of limiting grooves 32 can be arranged at equal intervals in the vertical direction, thereby realizing multi-level adjustment of the height of the seedling tray 21 to meet the precise ventilation requirements of seedlings at different growth stages. A support bar 33 is slidably connected inside the mounting frame 1. An inner groove 34 is opened at one end of the support bar 33 near the inner wall of the mounting frame 1. A sliding rod 35 is slidably connected inside the support bar 33. The inner groove 34 is "U" shaped, and the sliding rod 35 extends through the inner groove 34 to the support bar. Outside of 33, a locking block 36 is fixedly connected to one end of the sliding rod 35 near the inside of the inner groove 34. A tension spring 37 is sleeved on the surface of the sliding rod 35. The locking block 36 and the limiting groove 32 are matched and locked. One end of the tension spring 37 is fixedly connected to the surface of the locking block 36, and the other end is fixedly connected to the inner wall of the inner groove 34. A support rod 38 is fixedly connected to the surface of the support bar 33. The support rod 38 is shaped like a "well". The support rod 38 is matched and supported at the bottom of the hole 22. This "well" shaped structure can avoid the drainage hole 23 at the bottom of the hole 22 to the greatest extent, ensuring that the seedling needle 46 is unobstructed when it is pushed out.

[0031] Reference Figure 4 and Figure 6 The mounting frame 1 has a vertical groove 41 at its top. A telescopic rod 42 is fixedly installed on the bottom wall of the vertical groove 41. A pressure spring 43 is sleeved on the surface of the telescopic rod 42. The pressure spring 43 is preferably made of stainless steel to prevent rust caused by moisture in the seedling environment. A connecting sleeve 44 is fixedly installed at the top of the telescopic rod 42. The bottom end of the pressure spring 43 is fixedly installed on the bottom wall of the vertical groove 41, and the top end of the pressure spring 43 is fixedly installed on the bottom of the connecting sleeve 44. An insert rod 45 is inserted into the inner wall of the connecting sleeve 44. The two ends of the insert rod 45 are respectively inserted into the inner walls of the left and right connecting sleeves 44. The insert rod 45 is located directly above the support rod 38. The insert rod 45 and the connecting sleeve 44 can be interference-fitted, making the insert rod 45 a detachable structure, which facilitates the replacement of insert rods 45 of different lengths or shapes according to the size of the seedling tray 21.

[0032] In this invention, when in use, the seed tray 21 filled with substrate and sown is first placed inside the mounting frame 1.

[0033] When the plant's taproot comes into contact with the inner wall of the hole 22, it will touch the root guide ribs 24 fixed to the inner wall. The root system will enter the guide groove 25 in the middle of the root guide ribs 24 to grow. At this time, since the serrated strips 26 are set at equal intervals, continuous physical resistance points are formed. At this time, the serrated strips 26 not only increase the frictional resistance of the root system growing downward, forcing the root system to be unable to smoothly and quickly rush to the bottom, but also prevent the root system from crossing the ribs to spiral horizontally, thereby inducing the root system to differentiate more lateral roots during growth.

[0034] Meanwhile, the ventilation slits 27 on the inner wall of the hole 22 and the ventilation grooves 31 on the bottom side wall of the mounting frame 1 constitute a good air convection system. When the root tip grows to the ventilation slit 27 or comes into contact with the dry air outside through the drainage hole 23, the root tip meristem will dry naturally due to air pruning, thereby inhibiting the excessive elongation of the main root, promoting the explosive growth of fibrous roots, and finally forming a dense and evenly distributed root ball, avoiding the phenomenon of tangling at the bottom.

[0035] In the early stages of seedling cultivation, to prevent the ventilation slits 27 from causing low humidity inside the holes 22 and affecting growth, the holes 22 are located above the ventilation slots 31 on the mounting frame 1. At this time, the ventilation of the holes 22 is poor, keeping the humidity inside relatively high. When the seedlings grow larger, the sliding rod 35 can be pulled to move the locking block 36 away from the uppermost limiting slot 32, causing the support bar 33 to move the support rod 38 downward until the locking block moves and engages inside the lower limiting slot 32. At this time, the holes 22 also move downward with the support rod 38 to a position close to the ventilation slot 31. The grown seedlings can then achieve good ventilation through the ventilation slits 27 and the ventilation slots 31.

[0036] When seedlings are ready for transplanting, under normal seedling conditions, the support bar 33 is engaged in the limiting groove 32 on the inner wall of the mounting frame 1 via the locking block 36. At this time, the support bar 33 locks the seedling tray 21 in a suspended high position via the support rod 38. When removing seedlings, the operator moves the sliding rod 35, causing it to slide inside the support bar 33 and drive the locking block 36 to retract inward against the elastic force of the tension spring 37. When the locking block 36 disengages from the limiting groove 32, the support bar 33 is unlocked. After unlocking, the support bar 33 and the seedling tray 21 above it move downward, and the mounting frame 1 is then fixed in place. The seedling apical needle 46 on the bottom wall of the frame 1 will precisely align and pass through the drainage hole 23 at the bottom of the hole to enter the hole. As the seedling tray continues to descend, the seedling apical needle 46 will push the root and soil combination in the hole upward, separating it from the inner wall of the hole 22. At this time, the insertion rod 45 located directly above the support rod 38 will always be attached to the top of the hole 22 under the downward pulling force of the pressure spring 43, ensuring the stability of the hole 22 when the seedling apical needle 46 pushes upward. Finally, the seedling root ball is pushed out of the hole to a certain height, and the operator can easily remove it, realizing convenient seedling removal without damaging the roots or breaking the root ball.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
