Description

Technical Field

[0001] This utility model relates to the field of plant harvesting technology, and in particular to an alfalfa harvesting device. Background Technology

[0002] Alfalfa, also known as purple alfalfa, is the common name for plants in the genus *Alfalfa* of the family Fabaceae. Alfalfa thrives in sunny, moist conditions and is highly resilient, withering between July and September each year. Its stems are erect or spreading, with compound leaves; each leaflet has three leaflets, the upper margins of which are finely toothed, and stipules adnate to the base of the petiole; the flowers are small, yellow or purple, in short racemes or capitate inflorescences, axillary; the calyx teeth are nearly equal in length, and the standard petal is oblong or obovate. It is cultivated or found semi-wild throughout China. It grows in fields, roadsides, open fields, grasslands, riverbanks, and valleys. Alfalfa contains alfalfa polysaccharides, saponins, flavonoids, and unknown growth factors, among other bioactive substances, and has biological functions such as improving livestock and poultry production performance and immune function. It has wide applications in pig production. There are many methods for harvesting alfalfa, the most common being the use of harvesting devices to improve efficiency.

[0003] A search revealed that utility model publication CN211210475U discloses a tool for digging alfalfa cuttings. The tool includes a handle for easy gripping, with the lower end of the handle connected and fixed to a digging component via a telescopic element. The telescopic element includes a telescopic sleeve connected to the middle of the lower end of the handle, and a telescopic rod slidably fitted into a hole at the lower end of the sleeve. Foot pedals are provided on both sides of the telescopic rod for applying force with the feet, and bolts are screwed onto the outer side of the telescopic sleeve to hold the telescopic rod in place. This prior art allows for adjustment of the digging space, has a wide range of applications, and the soil blocks are detachable for easy replacement and maintenance. However, this prior art has the following drawbacks: First, after digging alfalfa, soil becomes embedded between the two soil blocks, requiring manual assistance with other tools for detachment, which is time-consuming and laborious. Second, the two soil blocks are positioned directly below the mounting plate, creating a blind spot and making it difficult to observe the digging process. Furthermore, using only one soil block for digging, due to its large area, leads to difficulty in digging, resulting in wasted time and effort.

[0004] Based on the above-mentioned technical problems, those skilled in the art urgently need to develop an alfalfa digging device that is simple in structure, can effectively remove soil after digging, has an offset digging part for easy observation, and is easy to insert into the ground.

[0040] See Figures 1-5 As shown;

[0041] This utility model discloses an alfalfa harvesting device, which includes:

[0042] The device includes a telescopic rod 1 and a handle 2. The telescopic rod 1 has a sleeve-like structure, and the handle 2 is connected to the upper end of the telescopic rod 1. A foot pedal 7 is installed through the lower part of the telescopic rod 1. The digging device also includes:

[0043] Adjustment part 3 is fixedly connected to the telescopic rod 1 via connecting sleeve 4 and is located on the side of the telescopic rod 1;

[0044] Two digging mechanisms 5 are provided below the adjustment part 3. Both digging mechanisms 5 have an arc-shaped structure and form digging cavities symmetrically with each other. The size of the digging cavity is determined by adjusting the distance between the two digging mechanisms 5 on the adjustment part 3. Both digging mechanisms 5 have multiple digging ends.

[0045] The excavation device also includes:

[0046] The cleaning mechanism 6 has multiple cleaning ends for cleaning the soil in the excavation chamber.

[0047] As a further description of this embodiment, the telescopic rod 1 includes a sleeve 101, and the handle 2 is connected to the upper end of the sleeve 101;

[0048] A sleeve rod 102 is adapted to the sleeve 101. Both the sleeve 101 and the sleeve rod 102 are provided with matching fixing holes and are connected by hexagonal bolts 103. Depending on the length required by the user, different fixing holes can be used to lock the connection using hexagonal bolts 103.

[0049] As a further description of this embodiment, the adjusting part 3 includes an adjusting block 301, which is fixedly connected to the connecting sleeve 4;

[0050] Multiple threaded holes 302 are provided on the adjusting block 301 for installing the digging mechanism 5;

[0051] The adjusting block 301 has a through hole 303 in the middle, through which the upper part of the cleaning mechanism 6 passes.

[0052] As a further description of this embodiment, the digging mechanism 5 includes a reinforcing rib 501 disposed at the lower end of the adjusting part 3, and the reinforcing rib 501 is arc-shaped;

[0053] The cleaning mechanism 6 has multiple cleaning ends that extend into the gaps between the multiple digging rods 502, which are evenly distributed at the lower end of the reinforcing rib 501. In this embodiment, the top of the reinforcing rib 501 has a threaded rod that passes through the adjusting block 301 and is fixed by a nut.

[0054] As a preferred technical solution in this embodiment, the end of the digging rod 502 away from the reinforcing rib 501 is a semi-circular cutting blade 503. When the digging rod 502 is in operation, the user only needs to step on the foot pedal 7 with a little force, and the cutting blade 503 extends into the soil, driving the entire digging rod 502 into the soil, thereby realizing the digging work, saving time and effort.

[0057] Multiple cleaning rods 604 are located at the lower end of the fixed plate 603. During use, after the digging mechanism 5 removes the alfalfa hay, soil remains in the digging chamber. At this time, the limiting pin 602 is released, and the push rod 601 is dragged to move the fixed plate 603 up and down, thereby causing the cleaning rods 604 to move up and down and remove the soil. It should be noted that the alfalfa hay has a certain height; during cleaning, the ends of the alfalfa hay are placed in the gaps between the multiple cleaning rods 604 to prevent damage to the alfalfa hay during the cleaning process.

[0058] As a preferred technical solution in this embodiment, both the reinforcing rib 501 and the digging rod 502 are made of stainless steel. During processing, the reinforcing rib 501 and the digging rod 502 can be integrally formed to improve toughness.
