Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of agricultural tools, and specifically relates to a ridging machine fertilizer stirring device. BACKGROUND

[0002] Fertilization refers to applying fertilizer to soil or spraying it on plants to provide nutrients required by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, cultivate soil fertility and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain sustainable development of agriculture. The main basis for fertilization is soil fertility level, crop type, target yield, climate and environment, and fertilizer characteristics, so as to select appropriate fertilizer, estimate the required amount of fertilizer, and determine the fertilization time and mode. According to different fertilization times, fertilization can be divided into base fertilizer and topdressing. According to different fertilization modes, fertilization can be divided into spreading, flushing, hole application and strip application. Spreading and flushing are beneficial to the diffusion of nutrients and are convenient to apply, but the nutrient loss is large and the utilization rate is low. Hole application and strip application have less nutrient loss and high utilization rate, but consume certain mechanical energy. With the development of modern precision agriculture, precise fertilization has also developed rapidly and will become an important fertilization mode.

[0003] In the process of agricultural ridging and fertilization, a ridging machine is needed to achieve the purpose of automatic operation. However, in the process of fertilization, the long-term accumulation of fertilizer inside the existing ridging machine can cause the fertilizer to coagulate into lumps, making subsequent discharging difficult and causing inconvenience in fertilization. In addition, the fertilizer needs to be added repeatedly, increasing the work intensity of personnel.

[0004] A patent with publication number CN212232059U is disclosed in the prior art, which includes a rack and a storage box. The bottom of the rack is fixedly connected with a stirring box, the top of the rack and the front of the storage box are fixedly connected with a motor, one end of the motor output shaft is fixedly connected with a rotating rod through a shaft coupling, the bottom end of the rotating rod penetrates through the stirring box and extends into the interior of the stirring box, the two sides of the top inner wall of the stirring box are rotatably connected with movable rods through bearings, and the surface of the rotating rod and the interior of the stirring box are fixedly connected with a first gear. The utility model relates to the technical field of agricultural machinery. The uniform fertilization stirring device for the ridging machine can uniformly mix the fertilizer inside the stirring box. The rapid rotation of the stirring rod and the heating work of the electric heating wire can prevent the fertilizer from coagulating into lumps inside the stirring box. At the same time, the storage box can store a certain amount of fertilizer, avoiding the problem of artificial repeated feeding and reducing the work efficiency.

[0005] The existing device gradually exposes the deficiencies of the prior art with use, mainly in the following aspects:

[0006] First, the fertilizer in the fertilizer box is prone to clumping due to moisture, which causes the discharge port to be easily blocked, and a blockage cleaning structure needs to be provided. The existing blockage cleaning structure is separately provided with a power source, which causes the structure to be complex and the failure rate to be high.

[0007] Second, the existing stirring structure in the fertilizer box has poor mobility of the fertilizer when stirring and crushing the material affected by moisture, which reduces the uniformity of the stirring of the fertilizer.

[0008] As can be seen from the above, the prior art has obvious inconvenience and defects in actual use, and therefore needs to be improved. Utility model content

The existing blockage cleaning structure is separately provided with a power source, which causes the structure to be complex and the failure rate to be high. In addition, the existing stirring structure in the fertilizer box has poor mobility of the fertilizer when stirring and crushing the material affected by moisture, which reduces the uniformity of the stirring of the fertilizer.

[0010] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0011] The fertilizer stirring device for a ridger comprises a fertilizer box, a discharge cylinder is fixedly connected to the bottom of the fertilizer box, two shafts are coaxially arranged in the fertilizer box, a plurality of rows of flow guide plates are arranged on the two shafts in the axial direction, the rotation directions of the two shafts are opposite, and the flow guide plates on the two shafts move the materials on both sides of the fertilizer box to the middle,

[0012] A discharge cylinder is fixedly connected to the bottom of the fertilizer box, a blockage cleaning plate is swingingly arranged in the discharge cylinder, the upper end of the blockage cleaning plate extends into the fertilizer box, a driving plate is fixedly connected to the shaft, and the upper end of the blockage cleaning plate intermittently rubs against the driving plate.

[0013] As an optimized scheme, first bevel gears are fixedly connected to the opposite ends of the two shafts, and a second bevel gear is rotatably arranged between the two first bevel gears through meshing.

[0014] As an optimized scheme, a cladding shell is fixedly connected in the fertilizer box, and the cladding shell clads the first bevel gear and the second bevel gear.

[0015] As an optimized scheme, a connecting rod is fixedly connected to the outer wall of the cladding shell close to one of the shafts, and the driving plate is fixedly connected to the other end of the connecting rod.

[0016] As an optimization scheme, the fertilizer box comprises a semi-cylindrical bottom shell matched with the rotating track of the guide plate, and a rectangular storage cylinder shell is fixedly connected to the upper end of the semi-cylindrical bottom shell.

[0017] As an optimization scheme, a driving machine is fixedly connected to the outer wall of the fertilizer box, and the output shaft of the driving machine is fixedly connected to the end of one of the rotating shafts.

[0018] As an optimization scheme, a conical guide block is fixedly connected to the top of the cover shell.

[0019] As an optimization scheme, support rods are horizontally fixedly connected to the opposite side walls of the cover shell, and the other ends of the support rods are fixedly connected to the inner wall of the fertilizer box.

[0020] As an optimization scheme, a rotating cylinder is horizontally fixedly connected to the middle position of the unblocking plate, a support shaft is horizontally fixedly connected between the opposite inner walls of the discharging cylinder, the rotating cylinder is rotatably sleeved on the support shaft, a torsional spring is arranged in the rotating cylinder, one end of the torsional spring is connected to the rotating cylinder, and the other end of the torsional spring is connected to the support shaft.

[0021] As an optimization scheme, a limiting column is fixedly connected to the side wall close to the upper end of the unblocking plate, and the other end of the limiting column abuts against the inner wall of the discharging cylinder.

[0022] As an optimization scheme, an annular mounting cavity is formed in the rotating cylinder, the torsional spring is sleeved on the support shaft, a first connecting block is fixedly connected to the shaft wall of the annular mounting cavity, a second connecting block is fixedly connected to the inner wall of the annular mounting cavity, and the two ends of the torsional spring are fixedly connected to the first connecting block and the second connecting block, respectively.

[0023] As an optimization scheme, the guide plate is inclined to the axial direction of the rotating shaft.

[0024] Compared with the prior art, the fertilizer box has the advantages that:

[0025] The fertilizer is poured into the fertilizer box, the axial directions of the two rotating shafts are opposite, the guide plate is used to realize the gathering of the materials on the two sides of the fertilizer box to the middle, the mobility of the materials is improved by the movement of the materials, and the stirring uniformity is improved.

[0026] By placing the discharge cylinder at the bottom center of the fertilizer box, the material inside the fertilizer box is discharged through the discharge cylinder. During the rotation of the shaft, the drive plate rotates circumferentially. Since a clearing plate is connected to the discharge cylinder by a torsion spring, when the drive plate rotates to the bottom, it abuts against the upper end of the clearing plate, thereby causing the clearing plate to swing. The swinging of the clearing plate will swing and discharge the material inside the discharge cylinder, preventing the material from clogging the discharge cylinder. Each time the drive plate rotates to the bottom, it drives the clearing plate to reciprocate once, thus achieving the clearing of the discharge cylinder. Moreover, no additional power source is required, making the structure simpler. Attached Figure Description
