Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a farmland fertilizer applicator with adjustable fertilizer application rate. Background Technology

[0002] Currently, crop fertilization is mainly carried out through mechanical and manual methods. Mechanical fertilization involves large, inconvenient, and costly equipment. In the later stages of plant growth, the increased size of the plants makes mechanical fertilization even more difficult, necessitating manual labor. However, manual labor is inefficient, time-consuming, and labor-intensive, requiring repeated bending and increasing the risk of lower back strain. Furthermore, existing fertilization techniques largely rely on experience, making precise application impossible and failing to achieve optimal fertilization results. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a farmland fertilizer applicator with adjustable fertilizer application rate. The device is equipped with a fastening cap and a pressing sleeve. When the fertilizer applicator body is pressed down, the pressing sleeve moves upward relative to the fertilizer applicator body. The push rod pushes one end of the fastening cap upward, so that the other end of the fastening cap no longer fastens the partition. The fertilizer falls through the filter screen of the partition. The user can fertilize without bending over, which effectively improves the user's fertilization efficiency and greatly avoids lumbar muscle strain caused by repeated bending over.

[0004] The device is equipped with an adjusting sleeve and a partition. By rotating the adjusting sleeve, different filters can be aligned with the storage chamber, thereby controlling the feeding speed of fertilizer in the storage chamber. This allows for effective control of the amount of fertilizer applied, significantly improving the precision of fertilization and greatly enhancing the fertilization effect.

[0005] This utility model also provides a farmland fertilizer applicator with the above-mentioned adjustable fertilizer application rate, comprising: a fertilizer applicator body, four inner sliding grooves are provided on the outer side wall of the fertilizer applicator body near the lower side, a sliding rod is fixedly connected inside each inner sliding groove, a pressing sleeve is slidably connected to the inner sliding groove through the sliding rod, and a push rod is fixedly connected to the inner side wall of the pressing sleeve.

[0006] The main body of the fertilizer applicator is provided with a feeding hopper, a storage chamber and a discharge chamber arranged from top to bottom. An adjusting sleeve is rotatably connected to the outer wall of the main body of the fertilizer applicator. A partition is fixedly connected inside the adjusting sleeve. Several filter screens are installed around the circumference inside the partition. A fastening cap is rotatably connected inside the discharge chamber.

[0007] According to the aforementioned adjustable fertilizer applicator, the pressing sleeve is slidably connected to the lower end of the applicator body, thereby improving the stability of the pressing sleeve's sliding motion.

[0008] According to the aforementioned adjustable fertilizer applicator, the feed hopper, storage chamber, and discharge chamber are interconnected, facilitating the discharge of waste materials from the fertilizer applicator.

[0009] According to the aforementioned adjustable fertilizer applicator, a feed hose is installed on the upper side wall of the main body of the applicator. A connection interface is fixedly connected to the upper end of the feed hose. The feed hose can be connected to an external waste supply device through the connection interface, thereby feeding fertilizer into the main body of the applicator.

[0010] According to the aforementioned adjustable fertilizer applicator for farmland, the partition is disposed between the storage chamber and the discharge chamber, and the filter pores of the plurality of filter screens are progressively larger to control the amount of fertilizer applied.

[0011] According to the adjustable fertilizer applicator, one end of the fastening cap engages with the upper end of the push rod, and the other end of the fastening cap engages with the partition. When the push rod pushes one end of the fastening cap, the fastening cap no longer engages with the partition, and the fertilizer falls through the filter screen of the partition.

[0012] According to the aforementioned adjustable fertilizer applicator for farmland, a return spring is provided on the outer wall of the sliding rod to facilitate the reset of the pressing sleeve.

[0013] According to the aforementioned adjustable fertilizer applicator for farmland, the lower end of the pressing sleeve is fixedly connected to a support base to increase the pressure between the main body of the fertilizer applicator and the ground.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Reference Figure 1-4 This utility model provides an adjustable fertilizer applicator for farmland, comprising: a fertilizer applicator body 1, a feed hose 4 installed on the upper side wall of the fertilizer applicator body 1, a connection interface 401 fixedly connected to the upper end of the feed hose 4, and the feed hose 4 can be connected to an external waste supply device through the connection interface 401 to feed fertilizer into the fertilizer applicator body 1.

[0025] Four inner sliding grooves 101 are provided on the outer side wall of the fertilizer applicator body 1 near the bottom. Each inner sliding groove 101 is fixedly connected to a sliding rod 102. A return spring 1021 is provided on the outer side wall of the sliding rod 102 to facilitate the reset of the pressing sleeve 3. The inner sliding groove 101 is slidably connected to the pressing sleeve 3 through the sliding rod 102. A support base 301 is fixedly connected to the lower end of the pressing sleeve 3 to increase the pressure between the fertilizer applicator body 1 and the ground. The pressing sleeve 3 and the lower end of the fertilizer applicator body 1 are slidably connected to each other to improve the sliding stability of the pressing sleeve 3. A push rod 302 is fixedly connected to the inner side wall of the pressing sleeve 3.

[0026] The fertilizer applicator body 1 has, from top to bottom, a feed hopper 103, a storage chamber 104, and a discharge chamber 105. These three chambers are interconnected to facilitate the discharge of waste materials. An adjusting sleeve 2 is rotatably connected to the outer wall of the fertilizer applicator body 1. A partition 201 is fixedly connected inside the adjusting sleeve 2. Several filter screens 202 are circumferentially installed inside the partition 201. A buckle is rotatably connected inside the discharge chamber 105. The cap 1051 and the partition 201 are located between the storage chamber 104 and the discharge chamber 105. The filter holes of the multiple filter screens 202 are progressively larger to control the amount of fertilizer applied. One end of the cap 1051 engages with the upper end of the push rod 302, and the other end engages with the partition 201. When the push rod 302 pushes one end of the cap 1051, the cap 1051 no longer engages with the partition 201, and the fertilizer falls through the filter screen of the partition 201.

[0027] Working principle: The device is equipped with a fastening cap 1051 and a pressing sleeve 3. When the fertilizer applicator body 1 is pressed down, the pressing sleeve 3 moves upward relative to the fertilizer applicator body 1. The push rod 302 pushes one end of the fastening cap 1051 upward, so that the other end of the fastening cap 1051 is no longer fastened to the partition 201. The fertilizer falls through the filter screen of the partition 201. The user does not need to bend over to fertilize, which effectively improves the user's fertilization efficiency and greatly avoids the lumbar muscle strain caused by repeated bending over. The device is equipped with an adjusting sleeve 2 and a partition 201. By rotating the adjusting sleeve 2, different filters can be aligned with the storage chamber 104, thereby controlling the feeding speed of fertilizer in the storage chamber 104. This allows for effective control of the amount of fertilizer applied, effectively improving the fertilization accuracy and greatly improving the fertilization effect.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
