Description

Technical Field

[0001] The invention relates to the field of strawberry planting, in particular to a fertilizing device for strawberry planting. Background Art

[0002] Strawberry is a perennial herb of the genus Fragaria in the Rosaceae family. It is widely popular because of its sweet and sour taste, rich nutrition and rich content of antioxidants such as vitamin C and anthocyanins. In order to ensure the good growth of strawberries, fertilizers need to be applied at different growth stages of strawberry planting to ensure soil fertility, so as to ensure the healthy growth of strawberries.

[0003] In the prior art, common fertilizer application devices mainly include vehicle-type fertilizer application devices and backpack-type fertilizer application devices. The backpack-type fertilizer application device mainly relies on manual carrying and spraying through a group of long nozzles. The overall spraying is more flexible but the spraying efficiency is low, and it is more laborious to use. The vehicle-type fertilizer application device mainly consists of a group of frames driving multiple groups of nozzles to move synchronously, so that a row of strawberries can be fertilized at a time, which is more efficient when used. However, when planting strawberries, the width of each row of strawberries is different, and the planting intervals between two adjacent rows of strawberries are also different. The common vehicle-type fertilizer application device has a frame that is mainly made of one-piece molding, so its body width cannot be adjusted, and its flexibility is poor when used. Therefore, a fertilizer application device for strawberry planting is proposed to solve the above problems. Summary of the Invention

[0004] In order to make up for the above shortcomings, the present invention provides a fertilizer device for strawberry planting, which aims to improve the problem in the prior art that "when fertilizing strawberries, there is a lack of a fertilizer device that is labor-saving and can adapt to different row widths and row spacings."

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a strawberry planting fertilization device, comprising: The left frame and the right frame are used to support the entire device. The left frame and the right frame are plugged into each other. The outer walls of the left frame and the right frame are jointly provided with a support assembly. A water pump is installed above the support assembly to provide power for spraying fertilizer. A liquid storage tank is installed above the support assembly to store fertilizer. A spray assembly is provided on the outer walls of the left and right frames for controlling the spraying position. The spray assembly includes a fixing frame, which is rotatably connected to the outer wall of the right frame. A closing sleeve is fixedly connected to the right surface of the fixing frame. Spray pipe 2 is plugged into the inner wall of the closing sleeve. A liquid feeding pipe is installed on the inner wall of the fixing frame. The liquid feeding pipe is plugged into the inner wall of the spray pipe 2. Spray pipe 1 is installed on the rear surface of the closing sleeve. The liquid feeding pipe and spray pipe 1 are connected to each other through a branch pipe. A ferrule is fixedly connected to the right end of the spray pipe 2. The ferrule is clipped to the outer wall of the left frame. Multiple groups of atomizing nozzles are installed on the outer walls of the spray pipe 1 and the spray pipe 2. The locking assembly is arranged on the outer wall of the fixing frame and is used to limit the rotation of the fixing frame.

[0006] As a further description of the above technical solution: The spray assembly also includes an adjusting bolt, which passes through and is threadedly connected to the front surface of the closing sleeve. An adjusting groove is provided on the front surface of the spray pipe 2. The adjusting bolt can be inserted into the inner wall of the adjusting groove to fix the closing sleeve and the spray pipe 2.

[0007] As a further description of the above technical solution: The lower surface of the sealing sleeve is provided with a spray hole, and the outer diameter of the spray hole is the same as that of the atomizing nozzle.

[0008] As a further description of the above technical solution: The outer wall of the liquid delivery pipe is fixedly connected with a sealing sleeve, and the sealing sleeve slides on the inner wall of the second spray pipe.

[0009] As a further description of the above technical solution: The locking assembly includes an insert block, which is slidably connected to the inner wall of the fixing frame. The outer wall of the right frame is provided with a locking groove, and the insert block is inserted into the inner wall of the locking groove.

[0010] As a further description of the above technical solution: A shift block is fixedly connected to the upper surface of the inserting block, and the shift block is elastically connected to the fixing frame via a locking spring.

[0011] As a further description of the above technical solution: The support assembly includes a support plate and a support sleeve. The support plate is fixedly connected to the outer wall of the right frame, the support sleeve is fixedly connected to the outer wall of the left frame, and the support plate is plugged into the inner wall of the support sleeve.

[0012] As a further description of the above technical solution: The inner wall of the support sleeve is fixedly connected with a threaded sleeve, the inner wall of the threaded sleeve is threadedly connected with an adjusting screw, the adjusting screw passes through and is rotatably connected to the left surface of the support plate, and the left end of the adjusting screw is fixedly connected with a turning handle.

[0013] As a further description of the above technical solution: The lower surfaces of the left frame and the right frame are both equipped with supporting legs in multiple groups.

[0014] As a further description of the above technical solution: A handle is installed on the outer wall of the left frame, and the handle is configured as a U-shaped telescopic rod, and the other end of the handle is installed on the outer wall of the right frame.

[0015] The present invention has the following beneficial effects: 1. In the present invention, a complete frame is formed by a left frame and a right frame. When performing fertilization operations, the total width of the entire device can be changed by adjusting the relative position between the left frame and the right frame. In this way, different planting widths and planting spacings can be adapted, and the entire device has better flexibility when used.

[0016] In the present invention, by setting an adjustable spraying assembly, when the width of the overall device changes, the spray pipe 2 will enter or leave the interior of the closed sleeve under the drive of the right frame, and the relative position of the liquid delivery pipe and the spray pipe 2 will also change. In this way, the part of the spray pipe 2 entering the interior of the closed sleeve will no longer spray fertilizer. Such a setting can prevent the spraying ranges of the spray pipes 1 and 2 from overlapping, resulting in excessive fertilization in some areas.

[0017] In the present invention, by setting the connection between the fixed frame and the frame body as a rotating connection, when it is necessary to fertilize the strawberries on the vertical strawberry stand, the fixed frame can be rotated to drive the entire spraying assembly to rotate to a vertical shape, so that the strawberries on the vertical strawberry stand can be fertilized. When in use, the entire device can adapt to a variety of planting conditions, and the entire device has good applicability.

[0018] In the present invention, by providing an adjusting bolt and an adjusting slot, when the overall device is used to fertilize strawberries on a vertical bracket, the spraying range of the overall spraying assembly can be actively controlled by adjusting the adjusting bolt and inserting it into different adjusting slots, thereby adapting to vertical brackets of different heights.

[0019] In the present invention, by adopting an adjustable frame, when the device is used to fertilize strawberries on a vertical bracket, the relative positions of the left frame and the right frame can also be adjusted. When the two sets of vertical brackets are placed at a small distance, the overall width of the frame can be adjusted so that the device can enter and exit a narrow space. When the entire device is not in use, the width of the entire device can also be reduced to facilitate the storage of the entire device, and the entire device is more convenient to use.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 、 Figure 3 and Figure 4 The present invention provides an embodiment of a strawberry planting fertilizing device, comprising: The left frame 1 and the right frame 2 are used to support the entire device. The left frame 1 and the right frame 2 are both set to U-shape. The left frame 1 and the right frame 2 are plugged into each other. After the left frame 1 and the right frame 2 are plugged into each other, a complete frame can be formed. By changing the plug-in amplitude of the two, the width of the entire frame can be changed. The outer walls of the left frame 1 and the right frame 2 are jointly provided with a support assembly 5, which can be used to support necessary components. A water pump 6 is installed above the support assembly 5 to provide power for spraying fertilizer. A liquid storage tank 7 is installed above the support assembly 5 to store fertilizer. The water pump 6 can extract the liquid inside the liquid storage tank 7 and transport it outward through a pipeline.

[0024] The spray assembly 3 is used to control the spraying position and is arranged on the outer wall of the left frame 1 and the right frame 2. The spray assembly 3 includes a fixed frame 31 for supporting the closed sleeve 32. The fixed frame 31 is rotatably connected to the outer wall of the right frame 2. The fixed frame 31 can rotate around the outer wall of the right frame 2, so that the spraying direction can be controlled. The right surface of the fixed frame 31 is fixedly connected to the closed sleeve 32 for accommodating the spray pipe 2 34. The inner wall of the closed sleeve 32 is plugged with a spray The inner wall of the fixing frame 31 is provided with a liquid feeding pipe 39 for feeding fertilizer to the spraying pipe 2 34. The liquid feeding pipe 39 is plugged into the inner wall of the spraying pipe 2 34. The liquid feeding pipe 39 can directly feed the fertilizer into the interior of the spraying pipe 2 34. The rear surface of the sealing sleeve 32 is provided with a spraying pipe 1 33 for spraying fertilizer. The liquid feeding pipe 39 and the spraying pipe 1 33 are connected to each other through a branch pipe 311. When the liquid feeding pipe 39 is connected to the water pump 6, the liquid feeding pipe 3 9 will also synchronously deliver liquid to the spray pipe 1 33 through the branch pipe 311. The right end of the spray pipe 2 34 is fixedly connected with a clamping sleeve 35, which is clamped on the outer wall of the left frame 1. The clamping sleeve 35 is made of plastic material and has good elastic deformation ability. It can fix itself on the outer wall of the left frame 1 through its own elastic deformation. Since the device does not experience violent shaking during use, the clamping sleeve 35 will not be separated from the left frame 1 at will. The outer walls of the spray pipe 1 33 and the spray pipe 2 34 are both equipped with multiple groups of atomizing nozzles 38. When a part of the spray pipe 2 34 enters the interior of the closed sleeve 32, the external opening of the part will be blocked by the inner wall of the closed sleeve 32, and the internal channel of the part will be blocked by the outer wall of the liquid feeding pipe 39, so that the part can be prevented from continuing to spray fertilizer. Such a setting can prevent the spray pipe 1 33 and the spray pipe 2 34 from overlapping in the spraying range, thereby causing excessive fertilization in some areas. The locking assembly 4 is disposed on the outer wall of the fixing frame 31 and is used to limit the rotation of the fixing frame 31 .

[0025] Reference Figure 2-Figure 4The spray assembly 3 also includes an adjusting bolt 36, which passes through and is threadedly connected to the front surface of the closing sleeve 32. By rotating the adjusting bolt 36, the adjusting bolt 36 can be driven to move back and forth on the outer wall of the closing sleeve 32. The front surface of the spray pipe 34 is provided with an adjusting groove 37 for accommodating the adjusting bolt 36. The adjusting bolt 36 can be inserted into the inner wall of the adjusting groove 37 to fix the closing sleeve 32 and the spray pipe 34. When it is necessary to control the position of the spray pipe 34 and the closing sleeve 32 separately, it can be achieved by adjusting the adjusting bolt 36 and inserting it into the adjusting groove 37. The lower surface of the closing sleeve 32 is provided with a spray hole 312 for supplying water mist to pass through. The spray hole 312 has the same outer diameter as the atomizing nozzle 38. The outer wall of the liquid feeding pipe 39 is fixedly connected with a sealing sleeve 310 for further sealing the internal channel of the spray pipe 34. The sealing sleeve 310 slides on the inner wall of the spray pipe 34.

[0026] Reference Figure 4-Figure 6 The locking assembly 4 includes an insert block 42 for fixing the fixing frame 31. The insert block 42 is slidably connected to the inner wall of the fixing frame 31. The outer wall of the right frame body 2 is provided with a locking groove 44 for accommodating the insert block 42. The insert block 42 is inserted into the inner wall of the locking groove 44. When the insert block 42 is inserted into the inner wall of the locking groove 44, the fixing frame 31 will be fixed and cannot rotate. The upper surface of the insert block 42 is fixedly connected to a shift block 41 for driving the shift block 42 to move. The shift block 41 and the fixing frame 31 are elastically connected to the locking spring 43. The upper surface of the fixing frame 31 is provided with a groove for accommodating the locking spring 43. This can prevent the locking spring 43 from excessive contact with the outside world and thus being damaged. Moreover, since the operation of the device does not require violent shaking, the locking spring 43 and the insert block 42 can fix the fixing frame 31. If it is necessary to further improve the fixing stability, it can be achieved by replacing the locking spring 43 with a larger elastic coefficient.

[0027] Reference Figure 1 、 Figure 6 and Figure 7The support assembly 5 includes a support plate 54 and a support sleeve 51. The support plate 54 and the support sleeve 51 can realize the support function by forming a complete plate body. The support plate 54 is fixedly connected to the outer wall of the right frame 2, and the support sleeve 51 is fixedly connected to the outer wall of the left frame 1. The support plate 54 is plugged into the inner wall of the support sleeve 51. The relative position of the left frame 1 and the right frame 2 can be changed by adjusting the plug-in state of the support plate 54 and the support sleeve 51. The inner wall of the support sleeve 51 is fixedly connected with a threaded sleeve 52 for accommodating the adjusting screw 53. The inner wall of the threaded sleeve 52 is threadedly connected with an adjusting screw 53 for driving the support plate 54 to move. The section screw 53 and the adjusting screw 53 pass through and are rotatably connected to the left surface of the support plate 54. There is no thread at the connection position between the adjusting screw 53 and the support plate 54. By rotating the adjusting screw 53, it can be driven to directly change its relative position with the threaded sleeve 52, so that the plug-in state of the support plate 54 and the support sleeve 51 can be changed. The left end of the adjusting screw 53 is fixedly connected with a turning handle 55, and the adjusting screw 53 can be driven to rotate by rotating the turning handle 55. The adjusting screw 53 used in this application has an outer wall external thread rise angle of less than 15°, so it can achieve self-locking, so there is no need to set an additional locking structure here.

[0028] Reference Figure 1 、 Figure 6 and Figure 8 The lower surfaces of the left frame 1 and the right frame 2 are both equipped with supporting legs 9 in multiple groups. The supporting legs 9 are composed of two components: an adjustable telescopic rod and a movable wheel. The height of the supporting legs 9 can be controlled by adjusting the adjustable telescopic rod, and the entire device can be supported to move by the movable wheel. Since the supporting legs 9 with a movable function are existing technology and can be implemented by people in this field, this case will not be described in detail. A handle 8 is installed on the outer wall of the left frame 1, and the handle 8 is set to a U-shaped telescopic rod. The other end of the handle 8 is installed on the outer wall of the right frame 2. The entire device can be driven to move by pushing the handle 8, and when the relative position between the left frame 1 and the right frame 2 changes, the width of the handle 8 will also change accordingly.

[0029] Working Principle: During use, rotating the handle 55 drives the adjustment screw 53, which engages the threaded sleeve 52, causing the support plate 54 to move within the support sleeve 51. This changes the insertion width between the left and right frames 1 and 2, adjusting the overall width of the device to accommodate different column widths and spacing. The wheels on the support legs 9 propel the device forward, and the U-shaped handle 8 facilitates operation.

[0030] The water pump 6 extracts fertilizer from the liquid storage tank 7 and delivers it to the spray pipe 1 33 and spray pipe 2 34 respectively through the liquid delivery pipe 39 and the branch pipe 311, and is sprayed by the atomizing nozzle 38. When the width of the device is adjusted, the spray pipe 2 34 enters and exits the closed sleeve 32 under the drive of the right frame 2, and the liquid delivery pipe 39 moves synchronously. The sealing sleeve 310 blocks the spray pipe 2 34 spray hole 312 in the closed sleeve 32 to avoid the spray range from crossing. When it is necessary to fertilize the strawberries on the vertical support, the dial block 41 is moved to disengage the insert block 42 from the locking groove 44, and the fixed frame 31 is rotated to vertical. At this time, the dial block 41 can be loosened, and the insert block 42 will be inserted into the locking groove 44 on the side of the right frame 2 under the drive of the locking spring 43. In this way, the fixed frame 31 can be re-fixed. Then the adjusting bolt 36 can be inserted into different adjustment grooves 37 to fix the spray pipe 2 34 and control the spray range to adapt to the height of the support.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
