Description

Technical Field

[0001] The utility model belongs to the field of agricultural equipment, and particularly relates to a handheld fertilizer applicator. Background Art

[0002] In the process of agricultural development, fertilizers, as substances that can provide necessary nutrient elements for crops, improve soil quality, and enhance soil fertility levels, are one of the basic substances for agricultural production. After years of development, fertilizer applicators have also been greatly improved. They are easy to operate as a whole and small in size, and can directly apply fertilizers to crops. Small fertilizer applicators on the market mainly consist of a backpack-type electric medicine storage barrel and a handheld fertilizer applicator. The storage barrel and the fertilizer applicator are connected by a hose. The motor in the fertilizer applicator drives the turntable to rotate, so that the granular fertilizer entering the fertilizer applicator makes a centrifugal motion.

[0003] In the actual use process, a part of the solid fertilizer is not only scattered into the soil from the opening of the fertilizer applicator, but also part of it hits the side wall of the fertilizer applicator. Since the fertilizer applicator is often made of materials such as plastic, the side wall of the fertilizer applicator is easily broken by the solid fertilizer, and parts of the fertilizer applicator need to be replaced, reducing the service life of the fertilizer applicator. Summary of the Invention

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose a handheld fertilizer applicator. The technical problem to be solved by the utility model is: how to improve the service life of the handheld fertilizer applicator.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A handheld fertilizer applicator includes a base and a cover connected to the base. The cover and the base cooperate with each other to form a discharge cavity. A turntable is provided in the discharge cavity. A baffle is provided between the turntable and the base. It is characterized in that a limiting groove is provided on the cover, the upper end of the side wall of the base is located in the limiting groove, an embedding groove is provided inside the lower end of the base, the upper end of the baffle is located in the limiting groove, and the lower end of the baffle is located in the embedding groove.

[0006] This application is a handheld fertilizer applicator. A layer of baffle is provided in the side wall of the fertilizer applicator base. In the actual use process, the solid fertilizer hits the baffle, avoiding the solid fertilizer directly hitting the side wall of the base, reducing the risk of the side wall of the base being broken, and improving the service life of the fertilizer applicator. The installation of the fertilizer applicator is to fix the connection after the cover and the base are installed in place, that is, the upper end of the side wall of the base is located in the limiting groove, the lower end of the baffle is set in the embedding groove, which has a preliminary limiting effect on the baffle and reduces the movement of the baffle. The limiting groove of the cover is set at the upper end of the side wall of the base. At this time, the upper end of the baffle is also located in the limiting groove. Through the above method, the installation and replacement of the baffle are convenient.

[0007] In the above-mentioned handheld fertilizer applicator, there is a gap between the baffle plate and the groove. The gap between the baffle plate and the groove prevents the baffle plate from closely adhering to the side wall of the base, facilitating the removal of the baffle plate from the groove.

[0008] In the above-mentioned handheld fertilizer applicator, the fertilizer applicator includes a discharge port, and a limiting block is provided at the discharge port in the groove. The limiting block prevents the baffle plate from moving from the discharge port along the side wall of the base to the outside of the fertilizer applicator.

[0009] In the above-mentioned handheld fertilizer applicator, the baffle plate is arranged along the side wall of the base, and the baffle plate is provided in a split or integral form.

[0010] In the above-mentioned handheld fertilizer applicator, an opening is provided on the base, the opening is located below the turntable, and a ring of retaining edge is provided at the edge of the opening.

[0011] In the above-mentioned handheld fertilizer applicator, the fertilizer applicator further includes a gearbox. The gearbox includes a box body and a cover plate. A first gear is provided inside the box body. A positioning shaft is provided on the box body. A first positioning groove is provided on the first gear. A first bearing is provided in the first positioning groove. The positioning shaft is located in the first bearing. A second positioning groove is provided on the cover plate. A second bearing is provided in the second positioning groove. A columnar first gear shaft is provided on the first gear. The first gear shaft is located in the second bearing. The arrangement of the positioning shaft and the second positioning groove facilitates the installation of the first gear in place.

[0012] In the above-mentioned handheld fertilizer applicator, a protrusion is provided on the cover plate, and a groove is provided on the box body. The protrusion is located in the groove. The provision of the protrusion on the cover plate and the groove on the box body helps the structures inside the gearbox to be installed in place, and at the same time can prevent the fertilizer in the discharge cavity from entering the gearbox, improving the service life of the fertilizer applicator.

[0013] In the above-mentioned handheld fertilizer applicator, a rotating shaft is connected to the first gear. The rotating shaft and the first gear shaft are integrally formed. The rotating shaft passes through the cover plate and is fixedly connected to the turntable. A limiting column is further provided on the first bearing. The side wall of the limiting column abuts against the second bearing. The integral formation of the rotating shaft and the first gear shaft facilitates the assembly of the fertilizer applicator, and the second bearing and the second positioning groove can prevent the rotating shaft from shifting during rotation.

[0014] In the above-mentioned handheld fertilizer applicator, a sealing groove is further provided on the cover plate. A sealing ring is provided in the sealing groove. The rotating shaft passes through the sealing ring, and the sealing ring is located below the first bearing. The sealing ring is arranged outside the rotating shaft to prevent the fertilizer in the discharge cavity from entering the gearbox, improving the service life of the fertilizer applicator.

[0015] In the above-mentioned handheld fertilizer applicator, the sealing ring is provided with an installation groove, and an annular spring is arranged in the installation groove. The annular spring enables the sealing ring to improve the sealing performance between the sealing ring and the rotating shaft.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1. A baffle is arranged in the side wall of the fertilizer applicator base. During actual use, solid fertilizer hits the baffle, avoiding direct hitting of the solid fertilizer on the side wall of the base, reducing the risk of the side wall of the base being broken, and improving the service life of the fertilizer applicator. The installation and replacement of the baffle are facilitated by arranging an embedding groove on the base and setting the upper end of the baffle in the limiting groove.

[0018] 2. The protrusions provided on the cover plate and the grooves provided on the box body contribute to the proper installation of the structures inside the gearbox. At the same time, it can prevent the fertilizer in the material discharge cavity from entering the gearbox, improving the service life of the fertilizer applicator. BRIEF DESCRIPTION OF THE DRAWINGS
