DETAILED DESCRIPTION

The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

Embodiment 1:

The present embodiment provides a technical solution: a preparation device for Simao pine pollen, as shown in FIG1 , comprising a material rack 1, a storage and receiving mechanism 4, a screening mechanism and a coating mechanism 5. It should be noted that: the present device is also externally connected to a power cord and a control switch to provide power to the present device and control the operation of the present device; in other embodiments, a battery can also be used as a power source (the specific connection methods all adopt existing and mature technical means, which will not be elaborated here).

As shown in Figures 1 and 2, the material rack 1 is composed of two cross bars and multiple transmission rollers rotatably installed between the two cross bars. The storage mechanism 4 is arranged on the material rack 1 to facilitate the sliding arrangement of the storage mechanism 4 on the multiple transmission rollers of the material rack 1.

As shown in Figure 10, the storage mechanism 4 includes two symmetrically arranged horizontal bars 41, and a bottom plate 42 is fixed at the bottom between the two horizontal bars 41. A plurality of partitions 43 are evenly fixed between the bottom plate 42 and the two horizontal bars 41, and the plurality of partitions 43 are distributed along the length direction of the horizontal bars 41. The spacing between the plurality of partitions 43 is set according to needs, and a storage groove is formed between two adjacent partitions 43. The plurality of storage grooves can store pine pollen to ensure the uniformity of the distribution of pine pollen and avoid excessive concentrated accumulation of pine pollen due to shaking; the partitions 43 are made of transparent material, such as acrylic panels, to prevent the partitions 43 from blocking sunlight, which is conducive to drying of the pine pollen.

As shown in Figures 1 to 3, the screening mechanism is located directly above the material rack 1. The screening mechanism is used to automatically screen the pine pollen, and the screened pine pollen falls into the storage mechanism 4 for storage; the screening mechanism includes a rectangular frame 21, and a swing component is rotatably installed on the inner side of the rectangular frame 21 through a rotating shaft 24, and the rotating shaft 24 is located at the center of the swing component. A second driving component 22 for driving the swing component to swing back and forth is provided on one side of the rectangular frame 21. The second driving component 22 can drive the swing component to swing back and forth left and right with the rotating shaft 24 as the reference point, and the unscreened pine pollen is placed in the swing component, and the pine pollen in the swing component is reciprocated left and right to achieve screening of the pine pollen.

As shown in Figures 3 and 4, the second driving component 22 includes a fan-shaped gear 221 fixed to one end of the rotating shaft 24 and an electric push rod 223 fixed to the rectangular frame 21. The telescopic end of the electric push rod 223 is fixed with a rack 222, and the rack 222 is meshed and connected with the fan-shaped gear 221. When the telescopic end of the electric push rod 223 is reciprocated, the rack 222 and the fan-shaped gear 221 can be used to drive the swing component to swing back and forth. At the same time, the swing amplitude of the swing component can be controlled by the telescopic length of the electric push rod 223.

As shown in Figures 1 to 3, there is a swing component including a screen 232, and a rectangular baffle 231 is fixed around the outer side of the upper surface of the screen 232. The rectangular baffle 231 can block the pine pollen to prevent the pine pollen from being scattered outside when swinging, and at the same time prevent the wind from blowing away the pine pollen in the swing component; in addition, a covering can be placed on the swing component to further improve the windproof performance.

As shown in Figures 2 to 5, the middle position of the rotating shaft 24 has a polygonal section, and the lower surface of the screen 232 is fixed with a sliding cylinder slidably connected to the polygonal section. In order to reduce the friction between the sliding cylinder and the polygonal section, a plurality of second balls are rotatably installed in an embedded manner on the outer surface of the polygonal section. A spring 25 sleeved on the rotating shaft 24 is provided between one side of the swing component and the inner wall of one side of the rectangular frame 21. The elastic force of the spring 25 will squeeze and push the swing member to the other side; a wave component 26 is provided between the other side of the swing component and the inner wall of the other side of the rectangular frame 21.

As shown in FIG5 , the wave assembly 26 includes two arcuate bars 261 fixed to the inner wall of the rectangular frame 21, and the two arcuate bars 261 are symmetrically arranged with the center of the rotating shaft 24, and the side of the arcuate bar 261 has a plurality of evenly distributed protrusions 262, and the number and distribution spacing of the protrusions 262 are set according to needs. Two mounting seats 263 are fixed on the rectangular baffle 231, and the ends of the two mounting seats 263 are both embedded with first balls 264 for rotation. The two first balls 264 are symmetrically arranged with the center of the rotating shaft 24, and the two first balls 264 are respectively in contact with the side surfaces of the two arcuate bars 261.

When the second driving component 22 is operated and the rotating shaft 24 drives the swing component to swing, the elastic force of the spring 25 will always apply a thrust to one side of the wave component 26 to the swing component. At the same time, as the swing component swings, the first ball 264 will slide on the arc strip 261, and due to the multiple protrusions 262, the swing component will be reciprocated laterally displaced, causing the swing component to vibrate, thereby increasing the effect of pine pollen screening.

As shown in Figures 1 and 2, a rectangular shielding portion 3 is fixed to the lower surface of the rectangular frame 21, and the two lateral portions of the rectangular shielding portion 3 are respectively fixed to the two side cross bars of the material rack 1, and the two longitudinal portions of the rectangular shielding portion 3 are both provided with notches 31, thereby forming an inlet and outlet on the upper side of the material rack 1, and the inlet and outlet can just be used for the storage mechanism 4 to enter and exit, so as to prevent the screened pine pollen from being blown away by the wind. It should be noted that the rectangular shielding portion 3 is made of plastic film or airtight cloth material to facilitate folding.

As shown in Figures 1 and 6, the screening mechanism and the material rack 1 are connected by two sets of telescopic mechanisms 6 to achieve adjustment of the material rack 1 and the screening mechanism to expand and fold, so as to facilitate storage and portability when not in use; the telescopic mechanism 6 includes two hinged connecting rods 61, the middle positions of the two connecting rods 61 are hinged to each other, one end of the two connecting rods 61 is hinged to the side of the screening mechanism and the side of the material rack 1, respectively, and the other ends of the two connecting rods 61 are movably connected to the side of the screening mechanism and the side of the material rack 1 through a connecting component.

As shown in Figures 1 and 6, the connecting component includes a slide rail 62 fixed to the side of the screening mechanism or the side of the material rack 1, that is, the two slide rails 62 are respectively fixed to the side of the screening mechanism and the side of the material rack 1, the slide rail 62 is a slide rail with a slide groove, the slide rail 62 is slidably provided with a slider 63, the corresponding end of the connecting rod 61 is hinged to the slider 63, the slide rail 62 is provided with an elongated through hole 65 arranged along the horizontal direction thereof, the slider 63 is screwed with a plum bolt 64 that passes through the elongated through hole 65, and the plum bolt 64 is abutted against the outer wall of the slide rail 62.

When it is needed, the screening mechanism is pulled upward to unfold the two connecting rods 61, and the slider 63 slides on the slide rail 62, and then the plum blossom bolt 64 is screwed to make the plum blossom bolt 64 contact the outside of the slide rail 62, thereby locking the slider 63 and the connecting rod 61, and the preparation work is completed; after use, the plum blossom bolt 64 is loosened, the screening mechanism is gradually placed downward, and the slider 63 slides on the slide rail 62, and finally the screening mechanism is in contact with the material rack 1, which can reduce the volume of the entire device for easy picking or storage. Since it is necessary to transfer to multiple places when taking pine pollen, this setting is convenient for operators to carry.

As shown in Figures 2 and 7, the coating mechanism 5 is installed at the transmission end of the material rack 1. The coating mechanism 5 includes a sealing cloth roll 51 and a first driving component. The first driving component is used to drive the storage mechanism 4 to move and cover the sealing cloth on the sealing cloth roll 51 onto the storage mechanism 4; to complete the automatic sealing of the storage mechanism 4, which can prevent the pine pollen in the storage mechanism 4 from being blown away by the wind during subsequent drying.

The cloth roller 53 can be removed to facilitate the replacement of the sealing cloth roll 51. The rotating shaft is fixed with two symmetrically arranged transmission disks 52, which are respectively located at the two ends of the rotating shaft, and the two transmission disks 52 correspond to the two horizontal bars 41 respectively.

As shown in Figures 7 to 9, the outer surface of the transmission disk 52 has a plurality of evenly distributed raised teeth 521, and the cross bar 41 is provided with a plurality of tooth grooves 411 arranged along its length direction, and the raised teeth 521 are meshingly connected with the tooth grooves 411, that is, when the transmission disk 52 rotates, the storage mechanism 4 is driven to move to the corresponding side through the cooperation of the tooth grooves 411, and the transmission relationship between the transmission disk 52 and the cross bar 41 is similar to a gear rack structure.

As shown in FIG8 and FIG11 , the sealing cloth of the sealing cloth roll 51 includes a film 511 , and clips 512 are fixed on both sides of the film 511 , wherein the film 511 is a transparent material, which is conducive to sunlight exposure to the storage mechanism 4 , and the clips 512 are rubber strips or ropes.
