Description

Technical Field

[0001] This application relates to the field of fertilizer quantitative application technology, specifically to a mechanical device for quantitative application of fertilizer in vegetable fields. Background Technology

[0002] In vegetable cultivation, proper fertilization is crucial for ensuring both yield and quality. Traditional field fertilization methods have several shortcomings. Manual fertilization often relies on experience to estimate the amount of fertilizer, making precise quantification difficult. This can lead to fertilizer waste and negatively impact vegetable growth if too much or too little fertilizer is applied. Furthermore, manual fertilization makes it difficult to control the fertilizer application angle and adjust it flexibly according to plant distribution and soil conditions, resulting in uneven fertilization. In addition, while some existing fertilization machinery improves efficiency to some extent, the equipment is not flexible enough, operation is complex, and it requires significant manpower and time. For example, the fertilizer dispensing mechanisms of some machines are complex in design and difficult to adjust, making it difficult to quickly adapt to the fertilization needs of different vegetable varieties and growth stages.

[0003] Therefore, in order to improve the scientific and precise level of vegetable planting, there is a need for a mechanical device for quantitative application of fertilizer in vegetable fields that can accurately control the amount of fertilizer applied, flexibly adjust the application angle, and is easy to operate. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted in this application is: a quantitative fertilizer application mechanical device for vegetable fields, including a trolley assembly, an application assembly, and an extrusion assembly. The trolley assembly is used to drive the application assembly and the extrusion assembly to move. The application assembly is used to carry and apply fertilizer, and the extrusion assembly is used to quantitatively control the waste material conveyed by the application assembly.

The frame is used to control the movement of the trolley assembly, the pivot is used to support the frame and wheels, and the wheels are used to drive the movement of the trolley assembly.

[0007] The delivery assembly includes a loading box, a conveying pipe, a metering pipe, and a delivery pipe. The loading box is tilted and mounted on the frame. The loading box has two output ports, each connected to a conveying pipe. The conveying pipe has a metering pipe, and the metering pipe has a delivery pipe. The metering pipe is used to control the amount of fertilizer delivered, and the delivery pipe is used to control the fertilizer delivery angle.

[0008] The extrusion assembly includes a rotating ring, a connecting seat, a telescopic rod, and an extrusion wheel. The rotating ring is fixedly mounted on the rotating shaft, the connecting seat is mounted on the rotating ring, and the two ends of the telescopic rod are connected to the connecting seat and the extrusion wheel, respectively. The rotating ring is used to follow the rotation of the rotating shaft and drive the extrusion wheel to approach and extrude the metering tube.

[0009] Preferably, the delivery assembly includes a platform and a diagonal brace. The platform is fixedly mounted on the frame, and there are two diagonal braces, which are respectively connected to the front and rear ends of the inclined surface of the loading box. The diagonal braces are used to support the inclined setting of the loading box.

[0010] Preferably, a valve is fixedly installed on the output port of the loading box, and the valve is used to control the opening and closing of fertilizer dispensing.

[0011] Preferably, the extrusion assembly includes a frame and a mounting rod. The frame is sleeved on the rotating shaft, and the mounting rod is fixedly installed at the end of the frame away from the rotating shaft.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] like Figures 1 to 8 As shown, a quantitative fertilizer application device for vegetable fields includes a trolley assembly 100, an application assembly 200, and an extrusion assembly 300. The trolley assembly 100 is used to drive the application assembly 200 and the extrusion assembly 300 to move. The application assembly 200 is used to carry and apply fertilizer, and the extrusion assembly 300 is used to quantitatively control the waste material conveyed by the application assembly 200.

[0031] The trolley assembly 100 includes a frame 101, a pivot 104, and wheels 106. The frame 101 rotates around the axis of the pivot 104, and the pivot 104 follows the rotation of the wheels 106. The frame 101 is used to control the movement of the trolley assembly 100, the pivot 104 is used to support the frame 101 and the wheels 106, and the wheels 106 are used to drive the movement of the trolley assembly 100.

[0032] Specifically, the frame 101 is provided with multiple support frames 102 and connecting rings 103. Each connecting ring 103 is provided with two support frames 102. The two support frames 102 are at an acute angle, and their ends away from the connecting rings 103 are respectively connected to the middle end of the frame 101. The frame 101 is supported by the support frames 102 and connecting rings 103 arranged symmetrically on both sides. The wheel 106 and the axle 104 are fixedly connected by multiple support rods 105, thus forming a complete vehicle body.

[0033] The dispensing assembly 200 includes a loading box 203, a conveying pipe 205, a metering pipe 206, and a dispensing pipe 207. The loading box 203 is inclinedly mounted on the frame 101. The loading box 203 has two output ports, each of which is connected to a conveying pipe 205. A metering pipe 206 is fixedly mounted on the conveying pipe 205, and a dispensing pipe 207 is fixedly mounted on the metering pipe 206. The metering pipe 206 is used to control the fertilizer delivery amount, and the dispensing pipe 207 is used to control the fertilizer dispensing angle.

[0034] Specifically, the bagged fertilizer is poured into the loading box 203. The inclined loading box 203 allows the fertilizer to slide along the inclined surface under gravity and enter the conveying pipe 205 for conveying. When it passes through the metering pipe 206, it works with the extrusion component 300 to control the metering. Then, the metered fertilizer is dispensed through the dispensing pipe 207. The dispensing pipe 207 has a corrugated structure and can be freely adjusted to adapt to different dispensing angles.

[0035] The extrusion assembly 300 includes a rotating ring 303, a connecting seat 304, a telescopic rod 305, and an extrusion wheel 307. The rotating ring 303 is fixedly mounted on the rotating shaft 104, the connecting seat 304 is disposed on the rotating ring 303, and the two ends of the telescopic rod 305 are respectively connected to the connecting seat 304 and the extrusion wheel 307. The rotating ring 303 is used to follow the rotation of the rotating shaft 104 and drive the extrusion wheel 307 to approach and extrude the metering tube 206.

[0036] Specifically, when the rotating shaft 104 rotates, it drives the connecting seat 304, telescopic rod 305, and extrusion roller 307 mounted on it to rotate via the rotating ring 303. This causes the extrusion rollers 307 to approach and extrude the metering tube 206 one by one. The two adjacent extrusion rollers 307 are used to control the amount of fertilizer on the metering tube 206. That is, the first extrusion roller extrudes the metering tube 206 first, preventing the fertilizer above the extrusion point inside from being conveyed downwards. Then, as the rotating shaft 104 rotates, the second extrusion roller 307 also contacts and extrudes the metering tube 206. At this time, the first extrusion roller has moved to a position below the metering tube 206, causing the fertilizer inside the metering tube 206 to move downwards by a certain distance. Thus, when the second extrusion roller extrudes the metering tube 206, the fertilizer between the extrusion points of the two extrusion rollers 307 is the amount of fertilizer controlled by metering. The distance between the extrusion points of the two extrusion rollers 307 is adjusted by adjusting the spacing of the adjacent connecting seats 304 mounted on the rotating ring 303, thereby realizing the metering adjustment of the fertilizer in the metering tube 206.

[0037] like Figure 1 and Figure 2 As shown, the delivery component 200 includes a platform 201 and a diagonal support frame 202. The platform 201 is fixedly installed on the frame 101. Two diagonal support frames 202 are provided, which are respectively connected to the front and rear ends of the inclined surface of the loading box 203. The diagonal support frame 202 is used to support the inclined setting of the loading box 203.

[0038] Specifically, the vehicle platform 201 is provided with multiple through slots, and the conveying pipe 205 passes through one of the through slots and connects to the output port of the loading box 203. The two diagonal braces 202 have the same structure but different specifications, and the two diagonal braces 202 are located at the feed port end and the output port end of the loading box 203, respectively.

[0039] like Figure 1 As shown, a valve 204 is fixedly installed on the output port of the loading box 203. The valve 204 is used to control the opening and closing of fertilizer dispensing.

[0040] Specifically, valve 204 is a manual mechanical valve. The conveying capacity of the conveying port is controlled by valve 204, thereby changing the fertilizer dispensing strategy when different dispensing needs are met, namely dispensing fertilizer from both sides simultaneously or dispensing fertilizer from only one side.

[0041] like Figure 3 As shown, the extrusion assembly 300 includes a frame 301 and a mounting rod 302. The frame 301 is sleeved on the rotating shaft 104, and the mounting rod 302 is fixedly installed on the end of the frame 301 away from the rotating shaft 104. A limit ring is provided on the mounting rod 302, and the metering tube 206 passes through the limit ring. The mounting rod 302 is used to stabilize the position of the metering tube 206.

[0042] Specifically, the frame 301 includes a connecting part and a supporting part. The connecting part is a ring structure and is fixedly installed with the connecting ring 103, so that the frame 301 does not follow the rotation of the rotating shaft 104, forming a stable support. The supporting part is a U-shaped bracket. Two connecting blocks are provided at the end of the bracket away from the connecting part for fixing the mounting rod 302. The mounting rod 302 is vertically set to support the metering tube 206 and resist the extrusion force generated by the multiple extrusion rollers 307.

[0043] like Figure 3 , Figure 5 and Figure 8 As shown, the rotating ring 303 is provided with multiple mounting slots, and the connecting seat 304 is provided with a mounting block 308. The mounting block 308 matches the mounting slots on the rotating ring 303, and the mounting block 308 is used to install the connecting seat 304 onto the rotating ring 303.

[0044] Specifically, a mounting block 308 is fixedly installed at the lower end of each connector 304. The connector 304 is inserted into the mounting groove of the rotating ring 303 through the mounting block 308, thereby installing the connector 304, telescopic rod 305 and extrusion wheel 307 onto the rotating ring 303.

[0045] like Figure 3 , Figure 5 and Figure 8 As shown, the rotating ring 303 is provided with fixing holes, and the connecting seat 304 is provided with a mounting plate 309. The mounting plate 309 is provided with through holes that match the spacing of the fixing holes of the rotating ring 303. The mounting plate 309 is used to fix the connecting seat 304 to the rotating ring 303.

[0046] Specifically, each connector 304 is fixedly mounted with a mounting plate 309, and the side of the mounting plate 309 facing the rotating ring 303 has an arc-shaped structure that matches the outer end face of the rotating ring 303. Thus, when the connector 304 is installed on the rotating ring 303, the mounting plate 309 is fixedly connected to the rotating ring 303 by bolts, thereby fixing the connector 304 and stabilizing its position.

[0047] like Figure 6 , Figure 7 and Figure 8As shown, a spring 306 is sleeved on the telescopic rod 305, and the two ends of the spring 306 are fixedly connected to the connecting seat 304 and the end of the telescopic rod 305 away from the connecting seat 304, respectively.

[0048] Specifically, when the extrusion roller 307 contacts the metering tube 206, it squeezes the metering tube 206 through the elastic force of the spring 306. As the rotating ring 303 rotates, the extrusion roller 307 gradually approaches the mounting rod 302. During this process, because the rotation radius of the extrusion roller 307 is greater than the distance between the rotation axis of the extrusion roller 307 and the mounting rod 302 (i.e., the distance between the axis of the rotating shaft 104 and the mounting rod 302), and because of the material thickness of the mounting rod 302 and the metering tube 206, the mounting rod 302 and the metering tube 206 will react on the extrusion roller 307, causing the extrusion roller 307 to push the telescopic rod 305, causing the telescopic rod 305 to extend and retract, and compressing the spring 306. Subsequently, as the extrusion roller 307 gradually moves away from the mounting rod 302, that is, as the actual rotation radius of the extrusion roller 307 gradually increases, the elastic force of the spring 306 pushes the extrusion roller 307, maintaining the extrusion roller 307's squeezing of the metering tube 206, thus preventing the fertilizer from being prematurely delivered.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
