Abstract

The invention provides a horseradish harvester which comprises a digging shovel, a chain type vibration screen, a conveyor belt and a collection box. The digging shovel is arranged on a rack and shovels soil of a horseradish ridge up so as to shovel horseradish together with soil blocks. The horseradish and the soil blocks move along a digging face of the digging shovel to enter the chain type vibration screen. The chain type vibration screen and the rack are connected and obliquely arranged. An eccentric connecting rod arranged on a power wheel drives the chain type vibration screen to move in a reciprocating mode. The soil blocks are shattered through the chain type vibration screen and attached soil vibrates to fall along meshes. The horseradish enters the conveyor belt along the chain type vibration screen and enters the collection box through the conveyor belt.

Description

A horseradish harvester

technical field

The invention provides a horseradish harvester, which belongs to the technical field of agricultural machinery.

Background technique

Horseradish is also called spicy dish. The spicy dish is cut off the stalks and roots, washed and pickled with salt. It is called horseradish salt dish, or tiger dish. It is a good condiment. Its main root can be used to treat rheumatism and neuralgia. Rub the horseradish on the gauze and apply it to the affected area. It will relieve pain in about 10 minutes.

The harvesting of horseradish in production is mainly done manually, using a hoe to plan, and manually picking up and shaking the soil, which is labor-intensive and inefficient.

Contents of the invention

The purpose of the present invention is to provide a horseradish fully automatic combined operation mechanical harvester, which can realize excavation, separation, and automatic collection, reduce manual harvesting costs, reduce labor intensity, high harvesting efficiency, and solve the technical problem of horseradish mechanized harvesting.

Its technical scheme is.

Including tractor, excavation equipment, chain vibrating screen, conveyor belt and collection box, the frame at one end of the tractor is equipped with excavation equipment, chain type vibrating screen, conveyor belt and collection box in turn, and multiple excavation equipment is installed on the frame Shovel, can harvest multiple rows at a time,

Adjust the installation position of the digging shovel on the rack. The digging shovel corresponds to the planting row of horseradish. The digging shovel is located at the position of the horseradish planting row. According to the difference in variety, the depth of the digging shovel on the frame can be adjusted. The digging shovel has multiple specifications Models, suitable for different varieties and sowing specifications. When the tractor is working in the field, it excavates and scoops up the soil in the horseradish planting ridge. The shoveled horseradish is subjected to the force of the excavation. The movement enters the chain-type vibrating screen. The chain-type vibrating screen is composed of a conveyor chain and an eccentric shaking mechanism. The conveyor chain is composed of rods that run through the screen frame at a certain distance. , There are multiple connecting and reinforcing rings between the two rods to prevent the rods from deforming. The screen frame is composed of multiple chain links. The rods rotate in the reinforcing rings. Flexible materials are installed on the rods, such as coated soft materials , or a set of hoses, with a conveyor chain on the outer surface of the roller motor, the roller motor rotates, the conveyor chain follows, the roller motor is a speed-regulating motor, and the chain shaker has the function of conveying and shaking separation. The vibrating screen is equipped with two sets of power systems, which are controlled separately. One set of power drives the conveyor chain to rotate, and the other set of power is provided by the power wheel. The conveyor chain rotates under the drive of the power, and the horseradish follows the conveyor chain. The horseradish and soil clods have the function of conveying. The eccentric shaking mechanism includes a power wheel, an eccentric connecting rod and a hanging rod to shake and separate the horseradish and soil clods. The frequency of shaking is controlled by the speed of the power wheel. The hinge is connected to the frame, and the other end is connected with the eccentric connecting rod set on the power wheel. The chain-type vibrating screen is installed obliquely with the frame. The angle between the chain-type vibrating screen and the horizontal line of the ground is 30-40°, and the included angle is less than 30°, horseradish and soil clods move fast on the chain-type vibrating screen, the separation effect of horseradish and soil clods is poor, the angle is greater than 40°, gravity is much greater than friction, horseradish and soil clods move slowly on the chain-type vibrating screen, The horseradish and soil clods of the chain vibrating screen are congested, and the separation effect of horseradish and soil clods is also poor. Both work efficiency and quality must be taken into account. Driven by the power wheel, the eccentric connecting rod drives the chain vibrating screen to reciprocate, and the dustpan is used for separation. The principle is that the greater the mass, the greater the inertia. The horseradish turns over and moves with each other on the chain-type vibrating sieve. The chain-type vibrating sieve shakes the soil clods and shakes the soil adhering to the horseradish and falls along the sieve holes to realize horseradish. The horseradish is separated from the clod, the horseradish enters the conveyor belt through the chain vibrating screen, and moves on the conveyor belt, the horseradish enters the collection box from the conveyor belt through the feeding port, and a tension spring is installed in the collection box, and the horseradish in the collection box When a certain weight is reached, a weight sensor is used to automatically alarm when a certain weight is reached. The unloading cylinder is extended and the bottom of the collection box is tilted, the discharge port is opened, and the collection box is automatically unloaded. In addition, there is a control panel on the tractor. On the control panel, the motors of the two sets of power trains use speed-adjustable motors. The manual harvesting process is cumbersome, and the mechanical harvesting can combine multiple manual harvesting processes together to complete it at one time. Other types of horseradish harvesters have a single function, only digging The function requires manual picking, shaking to remove soil, collection, and transportation. The process is complicated. In addition, agricultural machinery is highly specific, and special machines are dedicated. Corn cannot be harvested, there is no versatility, and there is no comparability, and it is impossible to compare a certain part or even another device with this file. Parts cannot replace the whole. The same device has different effects in different environments, not to mention It is different equipment, even if it is the same parts, different combinations, the effect of use is different, any comparison must be comparable, the chain shaker is equipped with a weight sensor, when the load of the chain shaker increases If it exceeds the allowable range, an automatic alarm will be issued, and the control system will adjust the walking speed of the tractor to implement variable harvesting. Due to differences in planting densities, there are differences in individual growth, so as to improve the quality of harvesting.

Compared with the prior art, the present invention has the following advantages.

1. The chain-type vibrating screen has the function of conveying and shaking separation. One end of the chain-type vibrating screen is hinged to the frame, and the other end is set at an angle of 30 degrees to the ground with the eccentric connecting rod on the power wheel. It adopts the dustpan principle to realize For the separation of horseradish and soil clods, the bar runs through the sieve frame, the distance between the two bars is smaller than the minimum diameter of the horseradish, and a silicone sleeve is provided on the bar to prevent the horseradish from turning over and moving on the bar. , The chain-type vibrating screen with large load is made of solid round steel to enhance the mechanical strength.

2. The conveying sieve has a large width and a large load capacity. There are multiple connecting and reinforcing rings on the two rods to prevent the rods from being deformed due to excessive harvesting weight. The separation of the pieces, and the removal of the dirt attached to the surface of the horseradish.
