Description

Pickup and collecting device using same

The technical field is as follows:

the invention belongs to the technical field of agricultural machinery, and particularly relates to a pickup and a collecting device using the same.

Background art:

china is a big agricultural country, mainly crops such as wheat, paddy and corn are planted, a large amount of agricultural wastes such as corn straws can be generated in farmlands after the crops are harvested, and the agricultural wastes such as the straws are also main sources of high-quality cattle and sheep feed. Therefore, abundant straw resources are matched with efficient straw picking and bundling equipment, the agricultural production efficiency can be effectively improved, and the utilization value of the straw can be improved. In recent years, in order to improve the efficiency of picking up agricultural waste such as straw, a mechanical picking up method using a baler is widely used, and a picker, which is an important component of the baler, picks up agricultural waste such as strawberries or straw scattered on the ground and conveys the agricultural waste to a feeding end of the baler, thereby realizing mechanical picking and baling operations. However, the conventional pickup has a high failure rate and a low pickup rate, and the reasons for this are as follows: the existing straw bundling machine is formed by transferring a pasture bundling machine, and the principles and the structures of the two machines are completely the same. The research of foreign pasture grass bundling machine starts in the 60 s of 20 th century, and goes through the development process from animal power as power to the power matched with a tractor, from a single machine tool to a multifunctional machine tool, and from a sectional harvester to a combined harvester. At present, the production links from planting to harvesting of pasture in developed countries in Europe and America basically realize mechanized and automatic operation, the product variety is complete, the function is complete, the pasture can basically meet different users, and the pasture harvesting machine is suitable for various harvesting conditions. Since most of the pasture grass is planted in a flat area of plain or sloping land, the pickup in the pasture grass pickup operation does not contact the ground surface, and crops such as corn are usually planted on ridge beds, which results in unevenness of the pickup ground. When ridge culture farmland is picked up for operation, the difference of height between a ridge and a furrow is considered, so that in the picking up process, in order to improve the picking rate, the elastic teeth of the picking up device can be in limited contact with the straws in the furrow only when being embedded into ridge soil. The pick-up device rotating at a high speed continuously carries out high-speed whipping on the straw cage platform and the soil on the ground surface, and sucks a large amount of soil (commonly called black soil) on the ground surface while picking up the straw, so that the problems of high soil content rate of grass and nutrient soil loss are caused, and in addition, the elastic teeth and the whole structure of the pick-up device can cause abnormal rapid abrasion due to non-standard use, so that the pick-up missing rate is high, and the energy consumption of equipment is increased; although the domestic grass baler imitation manufacturers also find the problems of high failure rate, difficulty in maintenance and the like, and adopt the shaftless horizontal elastic-tooth pickup to replace the traditional elastic-tooth pickup, the pickup principle is still the same, only at the cost of sacrificing the use function, the maintenance difficulty is reduced to a limited extent, but the problems of high equipment missing rate and high grass bale soil containing rate still exist, and after the pickup is used for a period of time, the problem that the missing rate is improved again due to the fact that the pickup equipment is still seriously abraded due to the fact that the unevenness of the picked ground still exists, the defect caused by the fact that the flat ground pickup operation is transferred to ridge crop waste pickup is not really solved, and unnecessary use cost is brought to users.

The invention content is as follows:

Example 13

A collecting device using the pickup device as in any one of embodiments 1-12, wherein the collecting device is a baler (also called a baler or a baler).

Currently, there are two main types of conventional baler, namely a round baler represented by F5500 manufactured by mikail corporation, and a square baler represented by the LSB series of kuen corporation. Both types of baler represent the principle of picking, bale forming and bundling of most and even all of the commercial balers. The shape of the bale is determined by the bale forming module and the bundling module, and the horizontal elastic teeth which are the same in technical scheme are used as the pickup devices of the baler.

The grass baler mainly comprises: pick up module, bale shaping module and tie up the module. In operation, a tractor with over 90 horsepower at least is used for traction, the PTO output shaft of the tractor is connected with the power input shaft of the baler, and PTO power is distributed to the picking module and the bale forming module by the power distribution mechanism of the baler to drive the picking module and the bale forming module to work. Wherein, the horizontal elastic teeth in the picking module rotate reversely to the advancing direction in operation.

The pickup module in the conventional baler is replaced with the pickup described in any one of embodiments 1 to 12, so that the pickup does not need power input such as a PTO or other power units, the overall horsepower requirement of the baler is effectively reduced, and the energy consumption is reduced.

The technical scheme of the embodiment is as follows:

taking a round bale baler (also known as a baler or baler) as an example, the baler described herein comprises: the technology is the same as that of the existing bale forming module and the existing bundling module, and the modules are used for realizing bale forming and bundling. Any one of the pickers of embodiments 4-12 is used as a pick-up module for collecting the object to be picked up on the ground.

The picker that this embodiment used is different with the operation direction of rotation of current module of picking up, preferably, installs the picker at the rear of bale shaping module, is connected with the organism of bale shaping module or baler through picker mounting bracket 2. Between the material inlet of the pickup and the bale forming module, a material conveying device is further arranged for conveying the peeled objects peeled off by the comb teeth 13 to the material inlet of the bale forming module. The conveying device can adopt the comb tooth 13 structure described in the embodiment 11, and the comb tooth 13 extends in a groove type or box type form.

In the pickup device of the baler, the object to be picked up is attached to the pickup pins 12 by the friction force generated by rolling on the ground during operation. The PTO power is only responsible for the power input of the bale forming module, and under the condition that the size of the bales is the same, the power requirement is only 50% -60% of that of the traditional baler, so that the fuel consumption of operation is greatly reduced.

In the above description of the solution, the pickup described in examples 4 to 11 can be combined with a conventional round bale baler to form a baler that is different from the conventional pickup principle. It will be appreciated by those skilled in the art that combining a bale forming module with a picker arrangement as described in any of the embodiments 1-3 of the present application, in combination with a picker mounting frame 2 of other shape or by other structural forms, can achieve the same technical solution as this embodiment without any inventive effort.

Similarly, the pick-up principle and pick-up structure of the existing square bale baler are the same as those of the circular bale baler. Therefore, by only constructing a material conveying device between the comb teeth and the bale forming module or providing conditions for transferring the picked-up material to the feed opening of the bale forming module (for example, moving the feed opening to be located at the end of the comb teeth 13) according to the above technical solution, the baler of the pickup according to any one of the application embodiments 1-12 of this embodiment can be realized.

In addition, because the rotatory rotational speed of ring of picking up is the same with the ground speed of tractor, and picks up needle 12 and not reverse friction with ground, does not take out and beat surface soil, so can effectively reduce the soil content rate in the straw package.
