Description

Technical Field

[0001] The utility model relates to a crop processing device, specifically, to a peanut shelling device. Background Art

[0002] During the processing of peanuts, a peanut shelling machine is needed to peel off the outer shell. The common peanut shelling machine on the market horizontally sets a roller in the shelling bin, sets the bottom of the shelling bin as an arc-shaped grid, and sets several axle rods or scraping plates on the surface of the roller. When in use, the shelled peanuts are placed on the arc-shaped grid. As the roller rotates, the outer shell is peeled off by the beating of the axle rods or scraping plates and the rubbing between the axle rods or scraping plates and the arc-shaped grid, and the peanut seeds are discharged from the gaps of the arc-shaped grid. However, since the sizes and shapes of peanuts are not completely the same, some seeds will be damaged during the collision with the axle rods, scraping plates, and arc-shaped grid.

[0003] The patent with the application number 201922230000.1 discloses a peanut seed shelling device that does not damage the fruits. By setting components such as a vertical rotating shaft, a shelling disc, a circular ring pressing plate, a spacing adjusting mechanism, and a compression spring, it can be applicable to shelling peanuts of different sizes and effectively reduce the bad fruit rate. However, this structure has the following disadvantages: (1) It completely abandons the structure of the traditional peanut shelling machine, and the improvement cost is relatively high; (2) The spacing adjusting mechanism includes several adjusting studs. When adjusting the spacing, each adjusting stud needs to be operated, which is not very convenient. When shelling, the raw materials must first drop to the circular ring pressing plate before they can be squeezed and shelled, and the shelling efficiency is relatively low.

[0004] In order to solve the above existing problems, people have been seeking an ideal technical solution. Summary of the Invention

[0005] The purpose of the utility model is to aim at the deficiencies of the prior art, and thus provide a peanut shelling device with scientific design, low improvement cost, not easy to squeeze and damage peanut seeds, and high shelling efficiency.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: A peanut shelling device, comprising a shelling bin, a feed hopper arranged on the shelling bin, and a drum and an arc-shaped grille arranged in the shelling bin. The arc-shaped grille is located below the drum. The arc-shaped grille comprises two arc-shaped plates, a plurality of metal rods parallel to the axial direction of the drum, and two mounting plates. Both ends of each metal rod are mounted on the two arc-shaped plates. Both ends of the two mounting plates are connected to the top ends of the two arc-shaped plates. The two mounting plates are respectively mounted on the inner wall of the shelling bin; the distances between the plurality of metal rods from the bottom end to the top end and the drum gradually increase. Rubber sleeves are respectively arranged at the end parts of the three metal rods at the lowest position, and mounting holes are respectively arranged on the arc-shaped plates corresponding to each rubber sleeve.

[0007] Based on the above, a widened section is arranged at the bottom of each arc-shaped plate, and a plurality of the rubber sleeves are all mounted on the widened section.

[0008] Based on the above, bosses are respectively arranged on the inner wall of the shelling bin corresponding to each mounting plate. The mounting plate is placed above the boss and the two are fixed by bolts. By increasing or decreasing the number of gaskets between the mounting plate and the boss, the height of the arc-shaped grille is adjusted.

[0009] Based on the above, the drum is of a hollow structure.

[0010] Based on the above, a plurality of axle rods or a plurality of scraping plates are arranged on the surface of the drum.

[0011] The present utility model has substantial features and progress compared with the prior art. Specifically, the present utility model has the following advantages:

[0012] (1) Since the distance between the metal rods at lower positions and the drum is smaller, the rubbing force of the metal rods at the lowest position on the peanuts is greater. By respectively arranging rubber sleeves at the end parts of the three metal rods at the lowest position, when rubbing the peanuts, the three metal rods at the lowest position have a certain elasticity, changing the traditional rigid contact, so that the peanut seeds are not easily broken.

[0013] (2) The arrangement of the widened section facilitates the installation of the rubber sleeve and the strength of the bottom of the arc-shaped plate.

[0014] (3) The arrangement of the boss facilitates the installation of the mounting plate. By increasing or decreasing the number of gaskets, the height of the arc-shaped grille can be adjusted to make the distance between the arc-shaped grille and the drum more appropriate; setting the drum as a hollow structure reduces the weight of the whole set of equipment.

[0018] Next, through specific embodiments, the technical solutions of the present utility model will be further described in detail.

[0019] As Figure 1 and Figure 2 shown, a peanut shelling device includes a shelling bin 1, a feed hopper 2 provided on the shelling bin 1, and a drum 3 and an arc-shaped grille provided in the shelling bin 1. The arc-shaped grille is located below the drum 3. In this embodiment, a plurality of shaft sticks 4 are provided on the surface of the drum 3. In other embodiments, a plurality of scraping plates can also be provided on the surface of the drum 3. Through the beating of the roller shafts 4 or the scraping plates and the rubbing with the arc-shaped grille, the outer shell is peeled off, and the peanut seeds are discharged from the gaps of the arc-shaped grille. The above equipment is a commonly used equipment in the field, and no creative labor is required to obtain it.

[0020] In order to reduce the breakage rate of peanut seeds, the arc-shaped grille includes two arc plates 5, a plurality of metal rods 6 parallel to the axial direction of the drum 3, and two mounting plates 7. Both ends of each metal rod 6 are installed on the two arc plates 5. Both ends of the two mounting plates 7 are connected to the tops of the two arc plates 5. The two mounting plates 7 are respectively installed on the inner walls of the shelling bin 1; the distances between the plurality of metal rods 6 from the bottom end to the top end and the drum 3 are gradually increased. Rubber sleeves 8 are respectively provided at the ends of the three metal rods 6 at the lowest position, and mounting holes are respectively provided on the arc plates 5 corresponding to each rubber sleeve 8.

[0021] Working principle:

[0022] Put the shelled peanuts into the shelling bin 1 from the feeding hopper 2, start the drum 3. As the drum 3 rotates, the shelled peanuts are slapped by the shaft stick 4 and rubbed in cooperation with the metal rod 6, and the outer shell is gradually peeled off. Since the distance between the metal rod 6 at a lower position and the drum 3 is smaller, the rubbing force of the metal rod 6 at the lowest position on the peanuts is greater. By respectively arranging rubber sleeves 8 at the ends of the three metal rods 6 at the lowest position, when rubbing the peanuts, the three metal rods 6 at the lowest position have a certain elasticity, changing the traditional rigid contact, so that the peanut seeds are not easily broken; moreover, this improvement is based on the structure of the traditional peanut shelling machine, and the improvement cost is lower.

[0023] To facilitate the installation of the rubber sleeve 8, a widened section 51 is provided at the bottom of each arc-shaped plate 5, and a plurality of rubber sleeves 8 are installed on the widened section 51. The widened section 51 also improves the strength of the bottom of the arc-shaped plate 5 and extends the service life.

[0024] To facilitate the installation of the mounting plate 7, a boss 9 is respectively provided on the inner wall of the shelling bin 1 corresponding to each mounting plate 7. The mounting plate 7 is placed above the boss 9 and the two are fixed by bolts 10. By increasing or decreasing the number of gaskets 11 between the mounting plate 7 and the boss 9, the height of the arc-shaped grille is adjusted; furthermore, the distance between the arc-shaped grille and the drum 3 can be adjusted to make the rubbing force more suitable.

[0025] To reduce the weight of the equipment, the drum 3 is of a hollow structure.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
