Technical Field

The utility model belongs to the technical field of shellfish collection equipment, a machine of digging is adopted to seashell is related to, refer in particular to a machine of digging is adopted to seashell's digging head assembly.

Background

At present, various shellfish cultured on coastal beaches in China are important components of seafood in China, with the continuous improvement of living standard of people, the demand of market sea shellfish is increased, but shellfish harvesting on beaches in various places is all captured by manpower, shellfish capturing on beaches needs to be operated according to tidal water time, the actual operation time is short, walking is inconvenient, heavy physical labor is involved, dirtying is tired, the current young people do not want to operate on the lower sea beaches, the old people who are healthy and experienced in the lower sea beaches operate, shellfish capturing efficiency in the lower sea by manpower is low, labor cost is high, accounts for more than 50% of culture cost, labor cost is particularly high in busy seasons, and labor cost is also difficult. In rainy, snowy and frozen weather, people do not talk about the operation of catching shellfish in the upper sea and the lower sea, the market consumption price is high, and the development of the beach shellfish farming industry is greatly restricted.

In order to improve the seashell collection efficiency, the current chinese patent network discloses a shellfish digging device [ grant publication No.: CN105052850U, which comprises a boat-shaped body, wherein the body is provided with a power mechanism, the bottom of the body is provided with a crawler traveling mechanism, the front part of the body is provided with a digging bin and a storage bin, the bottom of the digging bin is open, a digging wheel is arranged in the digging bin, the digging wheel is provided with a horizontal wheel shaft, the digging wheel rotates by taking the wheel shaft as a shaft, the rotating direction is opposite to the advancing direction of the body, and the bottom of the digging wheel extends downwards into silt from the opening at the bottom of the digging bin to dig shellfish; the digging wheel comprises two vertical flat plates fixed on a wheel shaft, the wheel shaft vertically penetrates through the centers of the vertical flat plates, a plurality of rectangular flat plates are arranged between the vertical flat plates, the rectangular flat plates are sequentially connected end to end around the wheel shaft, the distance between the center of the inner surface of each rectangular flat plate and the axial lead of the wheel shaft is equal, the rectangular flat plates are fixedly connected with the vertical flat plates, the tail end of each rectangular flat plate is provided with a row of claw nails which are distributed at equal intervals, the back surfaces of the claw nails are tangent to the outer surface of the other rectangular flat plate connected with the tail end of the rectangular flat plate, the front ends of the claw nails are bent, and the.

When the shellfish excavating device works, when the body is coated on a beach to move, the rotation direction of the excavating wheel is opposite to the proceeding direction of the body, the bent claw nails extend into the space below the sediment, and the shellfish in the sediment is excavated out along with the rotation of the excavating wheel, so the shellfish excavating device has the following defects: 1. the excavated shellfish falls on the rectangular flat plate, although partial silt flows out from gaps between the claw nails in the excavating process, most silt brought out by the excavated shellfish and the shellfish are mixed and piled on the rectangular flat plate, and along with the rotation of the excavating wheel, when the rectangular flat plate begins to incline, the shellfish and the silt slide down to the conveying device from the rectangular flat plate together under the action of self gravity, so that the conveying device is all a mixture of the shellfish and the silt, and the shellfish also needs to be manually sorted out from the silt, thereby not only having certain labor intensity, but also ensuring that the shellfish excavating efficiency is not high; 2. a large amount of mixture of silt and shellfish is accumulated on the rectangular flat plate, so that the weight of the excavating wheel is obviously increased, the burden of the excavating wheel during rotation is increased, the oil consumption of the excavator during working is greatly increased, and the cost for excavating the shellfish is increased; in addition, when the digging wheel is coated on the beach to dig the shellfish, silt coated on the beach can block the rectangular flat plate, the digging depth depends on the linear distance between the claw nail and the rectangular flat plate, and when the digging depth is greater than the linear distance between the claw nail and the rectangular flat plate, the digging wheel cannot rotate.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a seashell excavator's excavation head assembly, the utility model aims to solve the technical problem that: how to improve the shellfish digging efficiency and reduce the shellfish digging cost.

The purpose of the utility model can be realized by the following technical proposal:

the excavating head assembly of the seashell excavator comprises a main shaft and is characterized by further comprising a wheel plate, wherein a plurality of excavating teeth are sequentially arranged on the outer circumference of the wheel plate along the circumferential direction, the outer ends of the excavating teeth are bent along the forward direction to form hook parts, tooth grooves are formed between every two adjacent excavating teeth, and a shaft hole is formed in the center of the wheel plate; the wheel plates are arranged along the axial direction of the main shaft, gaps are formed between every two adjacent wheel plates, a plurality of excavating tooth rows are formed on the excavating teeth along the axial direction of the main shaft, tooth groove rows are formed between every two adjacent excavating tooth rows, the main shaft penetrates through a plurality of shaft holes, and the wheel plates and the main shaft rotate synchronously.

The excavating head assembly is installed on a seashell excavating machine for use, when the excavating head assembly is used, the main shaft rotates to drive all the wheel plates to rotate, the excavating tooth rows penetrate into a mud flat through the hook parts, along with the rotation of the wheel plates, silt and shellfish are carried out together after the excavating tooth rows are exposed out of the mud flat, and the silt and the shellfish are located in corresponding tooth groove rows.

Firstly, in the working process of the excavating wheel in the prior art, the excavated shellfish falls on the rectangular flat plate, although partial silt flows out from gaps between the claw nails in the excavating process, most silt and shellfish brought out by the excavated shellfish are mixed and piled on the rectangular flat plate, and along with the rotation of the excavating wheel, when the rectangular flat plate begins to incline, the shellfish and the silt slide down to the conveying device from the rectangular flat plate together under the action of self gravity, so that the conveying device is all a mixture of the shellfish and the silt, the shellfish also needs to be manually sorted out from the silt, and the excavating wheel not only has certain labor intensity, but also has low shellfish excavating efficiency; in the process of excavating the shellfish by circumferentially rotating the excavating head assembly, most of silt in the shellfish and silt mixture in the gullet row leaks downwards from the space between the wheel plate and the wheel plate under the action of self gravity and falls back to the beach for coating, and the shellfish cannot leak downwards from the space between the wheel plate and the wheel plate due to large volume, so that the separation of most of silt is finished before the shellfish is transferred to the conveying belt mechanism, and the silt and the shellfish can slide down to the conveying belt mechanism from the corresponding gullet row along with the rotation of the excavating head assembly, so that the silt on the conveying belt mechanism is less, the subsequent shellfish sorting is facilitated, and the shellfish sorting efficiency is improved.
