Description

Technical Field

[0001] The present invention relates to the technical field of fruit tree fertilization, and particularly relates to an intermittent organic fertilizer trenching, fertilizing and soil covering machine for orchards and an operation method thereof. Background Art

[0002] Fertilization refers to an agricultural technical measure of applying fertilizers to the soil or spraying them on plants to provide the nutrients required by plants and maintain and improve soil fertility. The main purposes of fertilization are to increase crop yields, improve crop quality, fertilize the soil, and improve economic benefits.

[0003] As disclosed in a Chinese utility model for an organic fertilizer trenching, fertilizing and soil covering machine for orchards (Publication No.: CN207911292U), it includes a frame, a fertilizer tank, a fertilizer conveying mechanism, a fertilizing mechanism, a trenching and soil covering mechanism, and a hydraulic control system. A fertilizer tank is fixed on the frame. Traveling wheels and lifting hydraulic cylinders are provided on the lower side of the frame. A support frame and a partition are provided inside the fertilizer tank. A scraper-type fertilizer conveying chain is provided below the fertilizer tank. A fertilizer outlet opening adjustment plate is provided behind the fertilizer tank. A fertilizing mechanism and a trenching and soil covering mechanism are provided behind the frame.

[0004] The current orchard fertilization devices have the following disadvantages: 1. Most of them adopt the method of directly spreading fertilizers after trenching. Spreading fertilizers is not only inefficient, time-consuming and laborious, but also unevenly spread, with poor fertilization accuracy, large waste, and easy to cause fertilizer accumulation and soil burning; 2. When covering the soil after fertilizing, if the soil covering thickness is too thick, it is easy to cause the fertilizer to exert its effect, and if the soil covering thickness is too thin, it is easy to cause fertilizer loss. The current soil covering plates are mostly single flip-type, which is not convenient for adjustment. Summary of the Invention

[0019] The present invention also provides an operating method for an intermittent orchard organic fertilizer trenching, fertilizing and soil covering machine, comprising the following steps:

[0020] Step 1: Connect the bottom box to the tail of the tractor body through a pair of fixed trusses and triangular trusses, and add an appropriate amount of fertilizer into the bottom box. The fertilizer in the bottom box enters the fertilizer groove.

[0021] Step 2: Start the first motor. The motor shaft of the first motor drives the driving sprocket to rotate synchronously. The driving sprocket drives a pair of driven sprockets and a pair of trenching shafts to rotate synchronously through a driving chain belt. The linkage sprockets on the trenching shafts drive the linkage chain and trenching teeth to rotate synchronously.

[0022] Step 3: Start the first hydraulic cylinder. The hydraulic telescopic rod of the first hydraulic cylinder slowly extends. With the cooperation of the hinge action, the trapezoidal frame is driven to slowly fall through the first swing arm, and the orchard land is trenched and loosened by a number of trenching teeth to form a trenching groove.

[0023] Step 4: Start the servo motor. The motor shaft of the servo motor drives the roller shaft and the crank to rotate synchronously. The crank drives the Z-shaped swing arm to perform a crank-link motion. Due to the limiting effect formed by the limiting pin shaft on the L-shaped rod and the first elliptical pin hole on the Z-shaped swing arm, the U-shaped notch on the Z-shaped swing arm alternately drives the fixed pin shaft, the fixed disk and the roller to rotate intermittently. As the roller rotates intermittently at the bottom of the bottom box, the fertilizer in the fertilizer groove intermittently drops into the trenching groove along the fertilizer pipe.

[0024] Step 5: Start the second hydraulic cylinder. The hydraulic telescopic rod of the second hydraulic cylinder slowly shortens. With the cooperation of the hinge action, the T-shaped plate and a pair of soil covering plates are driven to slowly fall through the second swing arm, so that the pair of soil covering plates are obliquely distributed on both sides of the trenching groove.

[0025] Step 6: Start the second motor. The motor shaft of the second motor drives the turntable to rotate synchronously. The eccentric pin shaft on the turntable forms a limiting effect with the second elliptical pin hole on the reciprocating swing arm, so that the reciprocating swing arm drives the first notched gear to reciprocate along the reciprocating shaft. The first notched gear meshes to drive the fixed gear, the swing shaft, the swing plate and a pair of second notched gears to reciprocate. The second notched gear meshes to drive the driven gear, the driven shaft and the soil covering plate to reciprocate, so that the pair of soil covering plates perform an alternating soil covering operation on the trenching groove and cover it on the fertilizer.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the present invention, the adjustment of the ditching depth is achieved through the first hydraulic cylinder, which facilitates adapting to the fertilization depths of different fruit trees. The crank drives the Z-shaped swing arm to perform a crank-link motion. Due to the limiting effect formed by the limiting pin shaft on the L-shaped rod and the first elliptical pin hole on the Z-shaped swing arm, the U-shaped notch on the Z-shaped swing arm alternately drives the fixed pin shaft, the fixed disk, and the roller to rotate intermittently. As the roller rotates intermittently at the bottom of the bottom box, the fertilizer in the fertilizer groove drops intermittently along the fertilization pipe into the ditching groove, enabling either single fertilization of organic fertilizer or mixed fertilization of organic fertilizer and chemical fertilizer.

[0028] 2. In the present invention, through the coordinated use of the linkage mechanism, the motor shaft of the second motor drives the turntable to rotate synchronously. The eccentric pin shaft on the turntable and the second elliptical pin hole on the reciprocating swing arm form a limiting effect, causing the reciprocating swing arm to drive the first notched gear to reciprocate along the reciprocating shaft. The first notched gear meshes to drive the fixed gear, the swing shaft, the swing plate, and a pair of second notched gears to reciprocate. The second notched gear meshes to drive the driven gear, the driven shaft, and the soil covering plate to reciprocate, enabling a pair of soil covering plates to alternately perform soil covering operations on the ditching groove. The soil covering plate is used to backfill the soil on both sides of the ditching groove into the ditching, resulting in a better soil covering effect.

[0029] In summary, the present invention solves the problems of low fertilization efficiency and inconvenient soil covering in orchards. Moreover, the overall structure is designed compactly, meeting the fertilization requirements for different row spacings and different fertilization depths. Through intermittent and uniform fertilization and timely soil covering operations, the fertilization effect of the fertilizer is effectively improved. The integrated and close cooperation of ditching, fertilization, and soil covering makes the processes of ditching, fertilization, and soil covering more coherent. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Embodiment 5: Specifically, the working principle and operation method of the present invention are as follows:

[0058] Step 1, the bottom box 1 is connected to the tail of the tractor body through a pair of fixed trusses 112 and triangular trusses 113, and an appropriate amount of fertilizer is added to the bottom box 1. The fertilizer in the bottom box 1 enters the fertilizer groove 104.

[0059] Step 2, start the first motor 206. The motor shaft of the first motor 206 drives the driving sprocket to rotate synchronously. The driving sprocket drives a pair of driven sprockets and a pair of ditching shafts 205 to rotate synchronously through the driving chain belt 207. The linkage sprockets on the ditching shafts 205 drive the linkage chain 208 and the ditching rake teeth 209 to rotate synchronously.

[0060] Step 3: Start the first hydraulic cylinder 203. The hydraulic telescopic rod of the first hydraulic cylinder 203 slowly extends. With the cooperation of the hinge action, the first swing arm 202 drives the trapezoidal frame 201 to slowly fall, and a plurality of ditching teeth 209 are used to loosen the orchard land and form ditching grooves.

[0061] Step 4: Start the servo motor 111. The motor shaft of the servo motor 111 drives the roller shaft 102 and the crank 107 to rotate synchronously. The crank 107 drives the Z-shaped swing arm 108 to perform a crank-link motion. Due to the limiting effect of the limiting pin shaft 110 on the L-shaped rod 109 and the first elliptical pin hole on the Z-shaped swing arm 108, the U-shaped notch on the Z-shaped swing arm 108 alternately drives the fixed pin shaft 106, the fixed disk 105 and the roller 103 to rotate intermittently. As the roller 103 rotates intermittently at the bottom of the bottom box 1, the fertilizer in the fertilizer groove 104 intermittently falls into the ditching groove along the fertilizer pipe 101.

[0062] Step 5: Start the second hydraulic cylinder 302. The hydraulic telescopic rod of the second hydraulic cylinder 302 slowly shortens. With the cooperation of the hinge action, the second swing arm 301 drives the T-shaped plate 3 and a pair of soil covering plates 312 to slowly fall, so that a pair of soil covering plates 312 are obliquely distributed on both sides of the ditching groove.

[0063] Step 6: Start the second motor 303. The motor shaft of the second motor 303 drives the turntable 304 to rotate synchronously. The eccentric pin shaft 305 on the turntable 304 and the second elliptical pin hole on the reciprocating swing arm 306 form a limiting effect, so that the reciprocating swing arm 306 drives the first notched gear 307 to reciprocate along the reciprocating shaft. The first notched gear 307 meshes to drive the fixed gear 308, the swing shaft, the swing plate 309 and a pair of second notched gears 310 to reciprocate. The second notched gear 310 meshes to drive the driven gear 313, the driven shaft 311 and the soil covering plate 312 to reciprocate, so that a pair of soil covering plates 312 alternately cover the ditching groove and cover the fertilizer.

[0064] The present invention solves the problems of low fertilization efficiency and inconvenient soil covering in orchards. Moreover, the overall structure is designed compactly, which can meet the fertilization requirements of different row spacings and different fertilization depths. Through intermittent and uniform fertilization and timely soil covering operations, the fertilization effect of fertilizers is effectively improved. The processes of ditching, fertilizing, and soil covering are closely coordinated in an integrated manner, making the processes of ditching, fertilizing, and soil covering more coherent.

The operating method of an intermittent orchard organic fertilizer trenching, fertilizing and covering machine according to claim 4, characterized in that, It includes the following steps: Step 1, the bottom box (1) is connected to the tail of the tractor body through a pair of fixed trusses (112) and triangular trusses (113), and an appropriate amount of fertilizer is added into the bottom box (1). The fertilizer in the bottom box (1) enters into the fertilizer groove (104). Step 2, start the first motor (206). The motor shaft of the first motor (206) drives the driving sprocket to rotate synchronously. The driving sprocket drives a pair of driven sprockets and a pair of ditching shafts (205) to rotate synchronously through a driving chain belt (207). The linkage sprockets on the ditching shafts (205) drive the linkage chain (208) and the ditching rake teeth (209) to rotate synchronously. Step 3, start the first hydraulic cylinder (203). The hydraulic expansion rod of the first hydraulic cylinder (203) slowly extends. Under the cooperation of the hinge action, the trapezoidal frame (201) is driven to slowly fall through the first swing arm (202), and the orchard land is ditched and loosened by a plurality of ditching rake teeth (209) to form a ditching groove. Step 4, start the servo motor (111). The motor shaft of the servo motor (111) drives the roller shaft (102) and the crank (107) to rotate synchronously. The crank (107) drives the Z-shaped swing arm (108) to perform a crank-link motion. Due to the limiting action of the limiting pin shaft (110) on the L-shaped rod (109) and the first elliptical pin hole on the Z-shaped swing arm (108), the U-shaped notch on the Z-shaped swing arm (108) alternately drives the fixed pin shaft (106), the fixed disk (105) and the roller (103) to perform intermittent rotation. As the roller (103) performs intermittent rotation at the bottom of the bottom box (1), the fertilizer in the fertilizer groove (104) intermittently drops into the ditching groove along the fertilizer application pipe (101). Step 5: Start the second hydraulic cylinder (302). The hydraulic telescopic rod of the second hydraulic cylinder (302) slowly shortens. Under the cooperation of the hinge action, the T-shaped plate (3) and a pair of soil covering plates (312) are driven by the second swing arm (301) to slowly fall, so that the pair of soil covering plates (312) are obliquely distributed on both sides of the trench opening. Step 6: Start the second motor (303). The motor shaft of the second motor (303) drives the turntable (304) to rotate synchronously. The eccentric pin shaft (305) on the turntable (304) forms a limiting effect with the second elliptical pin hole on the reciprocating swing arm (306), so that the reciprocating swing arm (306) drives the first notched gear (307) to rotate reciprocally along the reciprocating shaft. The first notched gear (307) meshes with and drives the fixed gear (308), the swing shaft, the swing plate (309) and a pair of second notched gears (310) to swing reciprocally. The second notched gear (310) meshes with and drives the driven gear (313), the driven shaft (311), and the soil covering plate (312) to swing reciprocally, so that the pair of soil covering plates (312) perform alternating soil covering operations on the trench opening and cover it on the fertilizer.
