Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a vibrating screen type stone picking machine. Background Art

[0002] Due to natural reasons, there are stones of different sizes distributed in farmland soil. For a long time, due to the lack of efficient and low-resistance farmland stone picking machinery and equipment, the stone picking work in farmland mainly uses manual assisted simple farm tools to dig, pick up and place them in the fields. Since some stones in farmland soil are on the surface and some stones are underground, when using manual treatment methods to treat stones in farmland soil, there are problems such as high labor intensity, time-consuming and labor-intensive, and high labor costs. Therefore, the manual stone picking treatment method will have an adverse effect on seed breeding and seed propagation. Therefore, it is urgent to study the picking mechanical device that can effectively realize low-resistance excavation of farmland soil stones and can efficiently separate soil and stones. It can not only improve its excavation effect, but also improve work efficiency, reduce the traditional manual labor intensity, and transform farmland farming quality, which has great practical significance.

[0003] Large or small stones are also common in farmlands in most mountainous and hilly areas. These stones not only affect the physical properties of the soil, such as water permeability, nutrient retention capacity, and hinder the growth of crop roots, but also increase the risk of machine failure during mechanized farming. Therefore, it is necessary to pick up the stones in the ground before farming.

[0055] A vibrating screen stone picker according to this embodiment has the following working process:

[0056] 1. Fix the traction frame of the stone picker to the matching tractor, and use the tractor output shaft to provide power to the gearbox through the transmission rod and the universal joint coupling. Adjust the digging depth through the sprocket depth adjustment device, adjust the digging angle of the digging shovel assembly through the adjustment rocker, and adjust the distance between the brush and the screen through the elastic pin and the limit hole; adjust the front and rear, upper and lower positions of the stone baffle, start the first stone-breaking motor, the vibration motor, and use the remote control to start the second stone-breaking motor to work at the same time, and the stone picker is driven by the tractor to move on the walking wheels;

[0057] Second, when the stone picker moves forward, the excavating shovel enters the ground, the sawtooth swing plate swings to break the soil, and the excavation and loosening operation is completed under the soil. Stones at a certain depth in the soil are dug up, and the stone baffle blocks the stones on both sides of the excavating shovel assembly to the middle, and are transmitted to the first conveying device together with the stones on the ground;

[0058] 3. The transmission mechanism transmits the power of the tractor to the first conveying device. The second motor for stone-breaking drives the stone-breaking roller to rotate through the belt. The first motor for stone-breaking drives the stone-breaking connecting rod assembly to drive the stone-breaking rotation driving assembly and the stone-breaking roller to move back and forth along the guide track on the conveying surface of the first conveying device and perform stone-breaking action. The stone-breaking roller breaks up the soil contained in the stone.

The first stone guide plates on the left and right sides of the rear end of the second conveying device gather the soil-rock mixture and guide it to the vibrating screen; the speed of the second conveying device is relatively fast, and the soil and rocks after the second screening can be thrown onto the vibrating screen in the ascending direction;

[0060] 5. The vibrating screen vibrates with the cooperation of the vibrating motor, screen crank, screen connecting rod and screen rocker to screen the soil and stone for the third time. The soil is screened out by the screen, and the soil on the stone can be further removed by collision with the screen. The stone falls to the rear end of the vibrating screen under the action of gravity and the inclined structure. The two second stone guide plates gather the stones and drop them into the stone collecting box along the stone plates, completing the screening and collection of the stones. When the stone collecting box is full, the stone picker is towed to the stone unloading place, the cover of the frame above the stone collecting box is opened, the stone collecting box is lifted to the stone pouring height through the stone collecting box lifting device, the first stone pouring motor and the second stone pouring motor are started, and the first stone pouring connecting rod, the second stone pouring connecting rod and the third stone pouring connecting rod are used to control the stone pouring connecting frame to drive the stone collecting box to flip, thereby completing the stone pouring action. After the stone unloading is completed, the stone collecting box is reset and the stone picker continues to work.

[0061] A vibrating screen-type stone picker of the present embodiment adopts a first conveying device, a second conveying device and a design of a vibrating stone brushing device. There is a height difference between the first conveying device and the second conveying device, which is convenient for removing soil blocks. At the same time, a stone-breaking mechanism is also arranged above the first conveying device serving as the first-level screening. Its stone-breaking function, combined with the reciprocating movement design, can fully break up the soil and stones on the first conveying device. In the vibrating stone brushing device serving as the third-level screening, the vibrating screen shakes to screen the soil, and the stone brushing device adopts two groups of brushes to move back and forth in an alternating manner, which can fully clean the soil blocks on the stones and also clean the soil on the vibrating screen to prevent the soil blocks from blocking the screen holes of the vibrating screen.

[0062] A vibrating screen-type stone picker in the present embodiment can adjust the digging depth of the digging device to a large extent through the sprocket depth adjustment device. At the same time, the design of the adjusting rocker arm can adjust the earth-entry angle of the digging device; and the swing design of the serrated swing plate of the digging shovel assembly is used to improve the earth-breaking effect of the digging shovel; so that the stone picker can adapt to different terrains and geologies and has high adaptability.

[0063] A vibrating screen-type stone picking machine in the present embodiment adopts the design of a stone collecting box lifting device. The stone collecting box can adjust the stone collecting height according to the actual working conditions to complete the collection of stones after soil and stone separation; the stone collecting box lifting device is designed to cooperate with the stone collecting box stone dumping device, and the first stone dumping motor drives the first stone dumping connecting rod to rotate, and then drives the second connecting rod to pull the top side of the stone dumping connecting frame to flip, and synchronously, the second stone dumping motor drives the second stone dumping connecting rod to rotate, and then drives the middle area of ​​the stone dumping connecting frame to flip, and the flipping amplitude is smaller than the flipping amplitude of the top side of the stone dumping connecting frame, so that the stone collecting box can perform the stone dumping action; the overall structural setting is relatively flexible, and can fully unload stones to avoid stone residues in the stone collecting box.

[0064] A vibrating screen-type stone picker in this embodiment can complete the functions of excavating, picking up, conveying, collecting, and unloading farmland stones at one time. It adopts a three-stage screening design of a first conveying device, a second conveying device, and a vibrating stone brushing device to separate soil and stones. It has high operating efficiency and good operating results, and can significantly reduce the labor intensity of manual stone picking.

[0065] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion shall fall within the protection scope of the present invention.
