Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a herringbone-shaped seeder pedal. Background Art

[0002] The pedal is a kind of auto part. With the development of science and technology, more and more seed drills are appearing in front of us. When the seed drill is working, the seeds are placed in a staggered manner so that the units are staggered with each other, forming a triangle, which we call a "pin" shape. The pedals on the "pin"-shaped seed drill are also varied. The pedals are generally used as auxiliary equipment for braking or acceleration, and play an important role in the braking of the locomotive. When the driver uses his feet to step on the pedal, it is easy to slip. In the prior art, a lot of research and design have been done on the problem of pedal anti-slip.

[0003] For example, a Chinese patent document with publication number CN109823320A discloses an anti-skid foot pedal for a seed drill, comprising a pedal body, a rubber pad fixedly mounted on the top of the pedal body, and anti-skid bumps on the top of the rubber pad. The foot pedal increases the friction between the pedal and the sole of the foot and reduces the chance of slipping by using the rubber pad and the anti-skid bumps. However, seed drills generally work in the fields, and the driver may have to work in the fields in addition to driving the seed drill. The soles of the driver's shoes are often stained with mud, and the presence of mud is likely to affect the anti-skid performance of the pedal and affect the driver's operation.

What is described here is only the preferred embodiment of the utility model. Those skilled in the art can think of other ways to implement the utility model based on the preferred embodiment, and other ways also fall within the scope of the utility model.

Therefore, they cannot be understood as limitations on the present invention.

[0032] Example 1

[0033] Reference Figure 1-Figure 4 The present embodiment provides a herringbone planter pedal, comprising a pedal body 1, a plurality of protrusions 2 are provided on the stepped surface of the pedal body 1, the protrusions 2 are in direct contact with the sole of the driver, and the protrusions 2 are conducive to increasing the friction between the sole and the pedal to prevent slipping. The protrusions 2 are provided with mud scraping holes 3, and the mud scraping holes 3 are used to scrape the mud off the sole. The mud scraping holes 3 can drain the scraped mud from the pedal body 1 to prevent mud accumulation, thereby improving the anti-skid performance of the pedal.

[0034] In order to achieve better scraping effect, Figure 2 and Figure 4 As shown, the scraping hole 3 is arranged through the top surface of the protrusion 2, and the scraping hole 3 forms two relative scraping surfaces on the top surface of the protrusion 2. The top surface of the protrusion 2 can contact the sole first and the area of ​​the top surface is relatively small, which can provide a large pressure when scraping mud and improve the efficiency of scraping mud from the sole. The relative scraping surfaces can scrape the mud on the sole when the sole reciprocates. The cross-sectional area of ​​the scraping surface is small, the cross-section is relatively narrow and long, and it has a strong scraping ability. When the sole reciprocates to scrape mud on the pedal body 1, the smoothness of the contact between the sole and the protrusion 2 must also be considered to avoid the sole from getting stuck on the protrusion 2. Therefore, the top surface of the protrusion 2 is designed as an arc surface, which can increase the softness of the contact between the protrusion 2 and the sole.

[0035] Sometimes the soles of shoes are stained with a lot of mud and the accumulation is thick, which is difficult to scrape off. Figure 4 As shown, a plurality of notches 301 are arranged at intervals along the length direction of the scraping surface, and a tooth structure 302 is formed between two adjacent notches 301. The tooth structure 302 is narrow in width, has a smaller contact area and force bearing area with the sole, and can scrape the mud on the sole more efficiently.

[0036] In this embodiment, in order to enable the protrusion 2 to have more contact with the sole and to scrape off a larger area of ​​mud at one time, the protrusion 2 is in the shape of an elongated strip, and the specific shape can be designed to be a rhombus or an ellipse. When the protrusion 2 is a rhombus, the scraping holes 3 are opened along the longer diagonal of the rhombus. When the protrusion 2 is an ellipse, the scraping holes 3 are distributed along the long axis of the ellipse. The length direction of the scraping holes 3 intersects with the movement direction of the shoe when scraping mud, and the scraping surface of the scraping holes 3 can fully contact the mud on the sole, so that the mud can be effectively scraped off. Ideally, the length direction of the scraping holes 3 is perpendicular to the movement direction of the shoe when scraping mud.

[0037] Although the scraping hole 3 also has the function of discharging mud, in order to further improve the mud discharging efficiency of the pedal, a mud discharging structure is provided on the pedal body 1. Specifically, Figure 2 As shown, the mud discharge structure includes a plurality of mud discharge holes 4 penetrating the pedal body 1. The mud discharge holes 4 and the protrusions 2 are arranged alternately. The scraped mud flows down from the mud scraping holes 3 and the mud discharge holes 4 at the same time, which greatly improves the mud discharge efficiency, further prevents the mud from accumulating on the pedal, and reduces the risk of slipping when stepping on the pedal.

[0038] Considering the storage of the pedal structure, such as Figure 2 and Figure 3 As shown, a connector 5 is provided on one side of the pedal body 1, and the connector 5 is used to connect the pedal body 1 to an external device. The connector 5 includes a first connecting arm 501 and a second connecting arm 502, the first connecting arm 501 and the second connecting arm 502 are hinged, the pedal body 1 is connected to the first connecting arm 501, and the second connecting arm 502 is connected to the external device. The pedal body 1 can be folded around the hinge point along with the first connecting arm 501, which can facilitate the storage of the pedal body 1. It should be noted that the external device here refers to the parts on both sides of the seeder for people to stand and observe the fertilizer box or seed box. Of course, the pedal structure can also be used in other positions of agricultural machinery, such as brake pedals, clutch pedals, accelerator pedals or boarding pedals.

[0039] In addition, the safety of the pedal body 1 during use and storage needs to be considered. A limiting structure is provided between the first connecting arm 501 and the second connecting arm 502. The limiting structure locks the connection state of the first connecting arm 501 and the second connecting arm 502. The connection state includes an unfolded state and a folded state. In this embodiment, in the unfolded state, the first connecting arm 501 rotates around the hinge point to a state where it is 180° with the second connecting arm 502. In the folded state, the first connecting arm 501 rotates around the hinge point to a state where it is at a right angle with the second connecting arm 502. Specifically, the limiting structure includes an elastic pin 6 and a pin hole 7. The elastic pin 6 is installed on the second connecting arm 502, and the pin hole 7 is provided on the first connecting arm 501. When the pedal is in the unfolded state, one end of the elastic pin 6 is clamped above the first connecting arm 501 under the action of the spring to prevent the first connecting arm 501 from folding around the hinge point; when the pedal is in the folded state, one end of the elastic pin 6 is clamped into the pin hole 7 under the action of the spring to achieve locking of the pedal.

[0040] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
