Description

Household material stirring device

Technical Field

The invention belongs to the technical field of household appliances, and particularly relates to a household material stirring device.

Background

The crops need to absorb nutrients in soil during growth, and in order to increase the yield and income of the crops, the farmland needs to be fertilized before and after cultivation. Substances which are applied to soil or can provide nutrients for crops through other ways or improve the physicochemical properties of the soil and provide good living environment for the crops are generally called fertilizers.

Before sowing seeds, fertilizers such as nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, organic fertilizer, trace element fertilizer, farmyard manure and the like and a proper amount of soil are required to be matched according to nutrient components of crops, and then are stirred, conveyed and preliminarily stored for use. In the technology of sowing seeds and chemical fertilizers at the same time, the stirred fertilizer is buried in soil below the seeds in a deep ploughing mode, and the fertilizer and the soil are mixed according to a proportion, so that the action timeliness of the fertilizer is prolonged, the utilization rate of the fertilizer is improved, and the yield of crops is further improved. When the existing fertilizer is mixed, manual mixing is generally carried out in the field, time and labor are consumed, and uniformity cannot be guaranteed; or the existing stirring mechanism is adopted for mechanical stirring, but the existing stirring mechanism has the problems of easy accumulation of fertilizer and incomplete stirring.

Disclosure of Invention

The invention aims to provide a household material stirring device to solve the problems of material accumulation and incomplete stirring.

In order to achieve the purpose, the basic scheme of the invention is as follows: a household material stirring device comprises a stirring barrel, wherein a rotating shaft is rotatably mounted in the stirring barrel, a first stirring rod is fixedly mounted in the middle of the rotating shaft, a cavity is formed in the rotating shaft, sliding grooves are formed in two ends of the cavity, sliding plates are slidably mounted in the two sliding grooves, two racks are fixedly connected between the two sliding plates, first chain wheels are rotatably mounted on the two sliding plates, the two first chain wheels are connected through a transmission chain, a power mechanism for driving the first chain wheels to rotate is arranged on the rotating shaft, two second stirring rods are slidably mounted on the rotating shaft, and a limiting mechanism for preventing the second stirring rods from freely sliding is further arranged on the rotating shaft; the inside activity chamber that runs through both ends that is equipped with of second puddler, activity chamber middle part is rotated and is connected with the drive wheel that can mesh with driving chain unilateral, the rigid coupling has drive gear on the drive wheel, drive gear can mesh with two racks, and the distance between two racks is greater than drive gear's diameter, the equal movable mounting in activity chamber both ends has the extension bar, be connected with the drive mechanism that the drive extension bar stretches out repeatedly on the drive wheel, the extension bar tip is equipped with pushing structure, the pivot middle part is equipped with the reversing mechanism that can promote the rack.

The working principle of the basic scheme is as follows: during the use, the pivot is passed through external power drive and is rotated, makes first puddler and second puddler rotate and stirs the mixture to the material. Meanwhile, the first chain wheel is driven to rotate through the power mechanism, the first chain wheel drives the other first chain wheel to rotate through the transmission chain, the transmission chain can drive the transmission wheel to rotate at the moment, the transmission wheel drives the transmission gear to rotate, the transmission gear rotates and can lift along the rack, and therefore the second stirring rod can lift. When the driving wheel rotates, the extension rod is repeatedly extended and retracted through the driving mechanism. When the second stirring rod moves upwards or downwards to touch the reversing mechanism, the reversing mechanism can push the rack to enable the sliding plate to slide in the sliding groove, so that the rack on one side is not meshed with the transmission gear any more, the rack on the other side is meshed with the transmission gear, and the directions of the two racks meshed with the transmission gear are opposite, so that the transmission gear rotates to move oppositely along the rack on the other side, and the reversing of the second stirring rod in the vertical direction is realized.

The beneficial effect of this basic scheme lies in: this scheme passes through driving chain, drive wheel, drive gear and the lift that the rack realized the second puddler, makes the second puddler can be at the agitator in-process up-and-down motion, has enlarged the stirring scope, makes the second puddler can be from last to stirring the material all-round down, stirs thoroughly, and the homogeneity of stirring is good. And the second puddler can be through drive mechanism drive extension bar at the in-process of going up and down and stretch out the withdrawal repeatedly, be equivalent to in the middle of the stirring process intermittent type nature increased the length of second puddler, thereby increase the conflict nature between second puddler and the material, make the activity of material in the agitator more violent, prevent that the material from forming in the agitator and piling up, improve the homogeneity of mixing, simultaneously because the extension bar tip is equipped with material pushing structure, can outwards release the material or inwards gather when making the extension bar stretch out the withdrawal, realize the material at the cyclic motion of horizontal direction, further improve the homogeneity of material mixing.

Furthermore, the inner threads are arranged in the movable cavities at the two ends of the second stirring rod, the outer threads matched with the inner threads are arranged on the surface of the extension rod, the material pushing structure comprises stirring blades, and the stirring blades are fixedly arranged at the outer end of the extension rod. So set up, can rotate when the extension bar stretches out or retracts to drive the stirring leaf and rotate, also carry out a stirring through the stirring leaf to the material on the horizontal direction, improve its misce bene, strengthen the circulation of material at the horizontal direction.

Furthermore, the transmission mechanism comprises crankshafts arranged on two sides of the transmission wheel, connecting rods are rotatably connected to the crankshafts, rotary sleeves are hinged to the other ends of the connecting rods, and the rotary sleeves are rotatably connected with the extension rods. According to the arrangement, the crank block mechanism is formed by the crankshaft, the connecting rod and the extension rod, the extension rod can be driven to extend and retract in a reciprocating mode when the driving wheel rotates, the existing driving wheel is used as a driving part, and the crank block mechanism is simple in structure and convenient to operate.

Further, the two ends of the second stirring rod are both sleeved with sleeve rods, the sleeve rods are slidably mounted on the second stirring rod, and the outer ends of the extension rods are rotatably connected with the end portions of the sleeve rods. Through setting up the loop bar, can protect stretching out the pole portion, avoid debris to disturb.

Furthermore, slide rails are fixedly mounted on two sides of the rotating shaft, the second stirring rod is slidably mounted on the slide rails, and the limiting mechanism is a friction gasket arranged between the second stirring rod and the slide rails. So set up, can guarantee the gliding property in the pivot of second puddler, can carry on spacingly again to the second puddler.

Further, reversing mechanism includes two slide bars of rigid coupling in two rack middle parts respectively, and two slide bars are located the upper and lower both sides of first puddler respectively, and lateral wall extends to the pivot outside about two slide bar tip pass the cavity respectively, slide bar and pivot sliding fit, and the tip of slide bar is the wedge form, all is equipped with the wedge groove with the slide bar on two second puddlers. So set up, go up or down through the second puddler and trigger the slide bar to realize the motion of rack.
