Description

TECHNICAL FIELD

[0001] The utility model relates to a crop planting and fertilizing device and belongs to the field of agricultural instruments. BACKGROUND

[0002] Crop planting and fertilizing is one of the key links in agricultural production, which is directly related to the yield and quality of crops. Reasonable fertilization can improve soil fertility and promote plant growth. The fertilizer particles are added in the bin body, and then the spreading structure for making the fertilizer fan-shaped diffusion is installed at the bottom of the bin body. When the agricultural machine carrying the bin body moves to the edge of the cultivated land, the fertilizer particles in fan-shaped diffusion are easily dropped on the ground of the cultivated land, which causes the waste of fertilizer. Therefore, a crop planting and fertilizing device for preventing the fertilizer particles from being spread on the ground outside the cultivated land is needed. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a crop planting and fertilizing device to solve the problems in the background art. The utility model realizes the limitation of the diffusion range of the fertilizer particles and prevents the fertilizer particles from being spread on the ground outside the cultivated land.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented by the following technical scheme: a crop planting and fertilizing device, comprising a bin body, four legs are installed at the four corners of the bottom of the bin body, a bottom frame is arranged directly below the bin body, a discharging bin is installed at the middle position of the bottom of the bin body, a screw rod is rotatably installed in the discharging bin, a speed reducer is installed on one side of the discharging bin through a support, the output shaft of the speed reducer is connected with one end of the screw rod, a blower is arranged on the lower side of the discharging bin and connected with the bottom frame, a rectangular pipe is installed on the air outlet end of the blower, the rectangular pipe is connected and communicated with the discharging bin through a vertical pipe, a detachable horn pipe is installed at the end of the rectangular pipe away from the blower, the cross-sectional area of the horn pipe gradually increases in the direction away from the rectangular pipe, a plurality of baffles are uniformly installed in the horn pipe, two symmetrically arranged baffles for limiting the diffusion range of the fertilizer particles are arranged at the end of the horn pipe away from the rectangular pipe, the baffles are connected with the legs through connecting pieces, a first plug-in slot vertically arranged is formed on one side of the baffle away from the bin body, the bottom of the first plug-in slot is closed, a plurality of elongated plates are arranged on the side of the baffle away from the bin body and plugged with each other, a plug-in strip is installed on one side of the elongated plate, the plug-in strip on one of the elongated plates is plugged in the first plug-in slot, a second plug-in slot is formed on the side of the elongated plate away from the plug-in strip, and the bottom of the second plug-in slot is closed.

[0005] Furthermore, a support plate is installed on the side of the baffle away from the horn tube, and a horizontal plate is connected and fixed on the side of the support plate away from the extension plate. The end of the horizontal plate away from the support plate is in contact with the support leg, and a positioning sleeve is fitted on the support leg. The two ends of the positioning sleeve are connected to the horizontal plate by bolts.

[0006] Furthermore, a plurality of ear plates are evenly provided on one side of the support plate and are connected and fixed to the corresponding extension plates. A first circular hole is opened on the side of the support plate facing the ear plate, and a second circular hole is opened on the side of the ear plate facing the support plate, which is concentrically arranged with the first circular hole. A screw is inserted into the channel formed by the first circular hole and the plurality of second circular holes. Nuts are threaded to both ends of the screw. The plurality of ear plates and support plates are arranged between two nuts on a screw.

[0007] Furthermore, the cross-section of the connector strip is "T" shaped, the cross-section of the first connector groove is "T" shaped, the cross-section of the second connector groove is "T" shaped, and the first connector groove and the second connector groove have the same specifications.

[0008] Furthermore, the upper end of the silo body is provided with a top cover, one end of which is hinged to the silo body via a hinge.

[0009] Furthermore, the bottom of the silo is a trapezoidal bucket structure, and the cross-section of the bottom of the silo gradually decreases from top to bottom.

[0010] The beneficial effects of this utility model are:

[0011] 1. When the geared motor is working, it drives the screw to rotate in the feeding bin. Under the drive of the screw, the fertilizer particles in the bin fall into the rectangular tube through the vertical pipe. Under the action of the wind generated by the blower, the fertilizer particles falling into the rectangular tube are spread in a fan shape through the trumpet tube with multiple baffles, so as to achieve the purpose of spreading fertilizer.

[0012] 2. When the agricultural machinery carries the container to spread fertilizer along the edge of the cultivated land, a structure consisting of multiple extension plates and baffles is set on the side of the trumpet tube closest to the edge of the cultivated land. The structure formed by the extension plates and baffles restricts the spread of fertilizer particles, thereby limiting the spread of fertilizer particles and preventing fertilizer particles from being spread to the ground outside the cultivated land.

[0013] 3. Insert the connector strip on one extension board into the second connector slot on another extension board to assemble two adjacent extension boards. Repeat this process to assemble multiple extension boards. Insert the connector strip on the extension board into the first connector slot to assemble the extension board and the baffle. This allows for adjusting the length of the structure formed by the extension board and the baffle as needed, and also facilitates the separate storage of the extension boards and the baffle.

[0014] 4. The screw rod is inserted in the channel formed by the first circular hole and the plurality of second circular holes, and the nut is screwed on both ends of the screw rod, thereby preventing the insertion strip from being detached from the first insertion slot or the second insertion slot due to vibration under the restriction of the screw rod.
