However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the utility model, and these aspects of the present utility model can be realized even without these specific details.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a mechanical device for ditching and topdressing in forestry, and the technical solution is as follows:

[0024] As Figures 1 - 2 shown, a mechanical device for ditching and topdressing in forestry includes a mounting base, a chemical fertilizer storage bin, a metering assembly and a ditching assembly. The mounting base includes a mounting part and a supporting part. The mounting part is fixedly arranged on the outer side wall of the supporting part. The mounting part is mounted on the working arm of the excavator, and the movement of the mounting base is controlled by controlling the movement of the working arm of the excavator. The mounting part is detachably connected to the working arm of the excavator, which is convenient for the installation and disassembly of the device. The supporting part includes an upper supporting body and a lower supporting body. The chemical fertilizer storage bin is arranged on the upper supporting body, and the chemical fertilizer storage bin is fixed on the upper supporting body by using a fixing plate. The fixing plate is connected to the upper supporting body through fastening screws. By tightening the fastening screws, the space between the fixing plate and the upper supporting body is reduced, and the chemical fertilizer storage bin is restricted on the upper supporting body to prevent the chemical fertilizer storage bin from shaking or disengaging from the upper supporting body during movement, which affects the construction efficiency.

[0025] As Figure 3As shown in the figure, the metering assembly is fixedly arranged inside the lower support body. Specifically, the metering assembly includes a metering frame, a guide rail frame, a temporary storage box, and a moving assembly. The metering frame is fixedly connected to the lower support body. The metering frame includes a central frame, an upper side plate, a lower side plate, a front side plate, a rear side plate, a left side plate, and a right side plate. The upper side plate, the lower side plate, the front side plate, the rear side plate, the left side plate, and the right side plate are respectively fixedly connected to the central frame to form a frame box. An inlet is opened on the upper side plate. A connecting plate is fixedly arranged on the inlet. A connecting cylinder is fixedly arranged on the connecting plate. The inlet is communicated with the fertilizer storage bin through the connecting cylinder. A guide rail frame is fixedly arranged inside the metering frame. The guide rail frame includes a mounting plate member and a guide rail plate member. The mounting plate member is installed inside the metering frame. A guide rail plate member is fixedly arranged on the mounting plate member. There are two guide rail plate members. The two guide rail plate members are arranged at intervals so that the space between the two guide rail plate members is hollowed out. Long strip-shaped guide rail holes extending along the length direction of the guide rail plate member are opened on the guide rail plate member. The temporary storage box is arranged between the two guide rail plate members. The temporary storage box includes a box body and a temporary storage pipe. An upper through hole is opened at the top of the box body. A lower through hole is opened at the bottom of the box body. The upper end of the temporary storage pipe is connected to the upper through hole. The lower end of the temporary storage pipe is connected to the lower through hole. The top of the box body is in contact connection with the upper side plate of the metering frame. The bottom of the box body is in contact connection with the lower side plate of the metering frame. Both sides of the box body are respectively connected to the long strip-shaped guide rail holes through sliding rods. The sliding rods are slidably connected to the long strip-shaped guide rail holes. That is, under the push of an external force, the temporary storage box can move on the guide rail frame. The moving assembly is fixedly connected to the box body. The box body is driven to move by using the moving assembly. Specifically, the moving assembly includes an oil cylinder and a connecting rod. The oil cylinder is fixedly arranged on the guide rail plate member. The output end of the oil cylinder is fixedly connected to the connecting rod. The end of the connecting rod far away from the oil cylinder is fixedly connected to the sliding rod. The oil cylinder is used to push the connecting rod to move. The connecting rod drives the sliding rod to move, so that the temporary storage box moves on the guide rail frame.

[0026] When the box body moves, when the upper through hole is aligned with the inlet, the fertilizer is led out from the fertilizer storage bin and drops into the temporary storage pipe through the inlet. Because the inlet and the outlet are arranged in a staggered manner, at this time, the lower through hole is blocked by the lower side plate, and the fertilizer accumulates in the temporary storage pipe. When the temporary storage pipe is filled, the oil cylinder is controlled again to drive the box body to move. When the lower through hole is aligned with the outlet, the fertilizer existing in the temporary storage pipe is discharged through the outlet. The application amount of the fertilizer can be controlled by setting the size of the temporary storage pipe, so as to accurately control the application amount of fertilizer for each fertilization and ensure the accuracy of fertilization.

[0027] The outlet is connected with a ditching assembly through a material guiding groove. The ditching assembly includes a fixed seat and a fertilizing hook. The fixed seat is fixedly connected to the lower end of the lower support body. The fertilizing hook is fixedly arranged on the fixed seat and is inclined relative to the vertical plane, which is convenient for the fertilizing hook to be inserted into the soil. A material guiding cavity is opened in the fertilizing hook. The material guiding cavity is communicated with the material guiding groove. A fertilizing port is opened at the bottom of the fertilizing hook. The fertilizing port is communicated with the material guiding cavity. After the fertilizing hook is inserted into the soil, the fertilizer is led out from the material guiding groove through the material guiding cavity from the fertilizing port, so as to apply the fertilizer to the soil and complete fertilization.

[0028] Further, it further includes two raking plates which are respectively and fixedly arranged on both sides of the fertilizer application hook. The raking plates have the same inclination angle as the fertilizer application hook, and saw teeth are arranged at the bottom of the raking plates. During the process of grooving the fertilizer application hook, the raking plates can clean the weeds around the groove, reducing subsequent cleaning steps, greatly saving working time and improving the fertilizer application efficiency.

[0029] Even further, it further includes a soil-returning plate which is fixedly arranged on the fixed seat through a fixed bracket. The soil-returning plate is arranged in an inclined manner, and the inclination angle of the soil-returning plate is opposite to that of the fertilizer application hook. After the fertilizer application hook grooves and finishes fertilizer application, the soil-returning plate can be used to backfill the groove to complete the fertilizer application.

[0030] During use, the device is installed on the forearm of the excavator through the installation part. First, control the boom and stick of the excavator to use the fertilizer application hook to complete weeding and trenching operations. Then, control the oil cylinder, and the oil cylinder drives the temporary storage box to move so that the upper through hole of the temporary storage box is aligned with the feed inlet of the metering frame. The chemical fertilizer falls from the chemical fertilizer storage bin through the upper through hole into the temporary storage pipe. When the temporary storage pipe is full of chemical fertilizer, control the oil cylinder again, and the oil cylinder drives the temporary storage box to move until the lower through hole of the temporary storage box is aligned with the discharge outlet of the metering frame. The chemical fertilizer falls from the temporary storage pipe, passes through the guide chute and falls into the fertilizer application hook, and then is discharged from the fertilizer application port of the fertilizer application hook to complete the fertilizer application on the soil. Finally, control the boom and stick of the excavator to use the soil-returning plate to complete the soil-returning and leveling operation.

[0031] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
