They come from a large number of microorganisms in nature, from which useful bacteria are separated and screened, then improved and stored for production. In the preparation process of biological fertilizer, biological bacteria need to be continuously added so that they can be processed according to demand.

Then, the feeding tube is added and inserted into the support tube sleeve, so that the feeding tube can be sealed by contacting the inner wall of the support tube sleeve through the sealing rubber ring and the blocking rubber strip. By holding the support tube sleeve and fixing it, the feeding tube can be pushed through the connecting strip to push the hand-held handle to slide and push it out in the support tube sleeve. When the blocking rubber strip is exposed, the material in a single cavity separated by the portion partition can be poured out, so as to facilitate quantitative pushing for feeding, achieving the effect of quantifying and controlling single feeding, achieving the goal of facilitating multi-frequency quantitative feeding, achieving precise feeding, and making it more convenient to precisely control the feeding of microbial inoculants.

[0004] The above technology cannot continuously and quantitatively add liquid materials multiple times during feeding, which leads to low working efficiency and inaccurate feeding amount. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a strain adding mechanism, which solves the problem that liquid materials cannot be added quantitatively multiple times continuously during feeding, thus resulting in low work efficiency and inaccurate feeding amount.

[0011] Preferably, a buffer pad is installed on the outer surface of the piston, and the buffer pad corresponds to the telescopic rod.

[0012] Preferably, a handle is installed on the outer surface of the incomplete gear.

[0013] Compared with the prior art, the utility model provides a strain adding mechanism, which has the following beneficial effects:

[0014] (1) When the strain adding mechanism is in use, a liquid storage chamber is formed between the piston and the inner wall of the sleeve. By pushing the piston, the liquid material in the liquid storage chamber is discharged to the working position through the liquid outlet pipe, thereby achieving the effect of adding materials. When the piston is released, the piston moves in the opposite direction under the elastic force of the spring, and the material in the storage bottle is drawn into the liquid storage chamber in the sleeve through the liquid inlet pipe, thereby achieving the effect of recycling.

[0015] (2) The fungus adding mechanism is provided with a handle, which is turned to drive the incomplete gear to rotate, so that the rack frame drives the slider to move back and forth along the direction of the slide groove. The slider drives the telescopic rod to move back and forth through the bracket. When the telescopic rod moves toward the piston, it continues to move until it hits the piston. The telescopic rod pushes the piston to move and squeezes out the material in the sleeve.

[0016] (3) The fungus adding mechanism rotates the screw rod so that the threaded sleeve drives the top plate to move along the direction of the slide rod, thereby adjusting the distance between the top plate and the piston. When the distance is larger, the amount of material extruded each time the handle is rotated is smaller. Conversely, the amount of material extruded is larger, thereby adjusting the amount of basic material each time, thereby expanding the use of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] See also Figure 1-4 Embodiment 1, a strain adding mechanism, comprises a sleeve 1, a pushing mechanism 2 and a storage bottle 3. The outer surface of the sleeve 1 is provided with a scale, and the minimum unit of the scale is milliliter, which plays the effect of convenient observation and use. A piston 101 is provided inside the sleeve 1, and a spring 102 is fixedly connected between the piston 101 and the inner wall of the sleeve 1. A liquid outlet pipe 103 and a liquid inlet pipe 104 are fixedly installed on the outer surface of the sleeve 1. The sleeve 1 and the storage bottle 3 are connected by threads, and one end of the liquid inlet pipe 104 extends to the interior of the storage bottle 3.

[0023] When in use, a liquid storage chamber is formed between the piston 101 and the inner wall of the sleeve 1. By pushing the piston 101, the liquid material in the liquid storage chamber is discharged to the working position through the liquid outlet pipe 103, which has the effect of adding materials. When the piston 101 is released, under the elastic force of the spring 102, the piston 101 moves in the opposite direction, and the material in the storage bottle 3 is drawn into the liquid storage chamber in the sleeve 1 through the liquid inlet pipe 104, which has the effect of recycling.

[0024] Embodiment 2, the pushing mechanism includes an internally hollow installation box 201 and a telescopic rod 4, the inner side wall of the installation box 201 is rotatably connected with an incomplete gear 202, and the outer surface of the incomplete gear 202 is provided with a handle, which is convenient for operation and use, and the inner top wall and bottom wall of the installation box 201 are provided with a slide groove 203, and the insides of the two slide grooves 203 are slidably connected with a slider 204, and a rack frame 205 is fixedly connected between the opposite ends of the two slide grooves 204, and the rack frame 205 is connected to the incomplete gear 202. The outer surface of the rack frame 205 is meshed with each other, and a bracket 206 is fixedly installed thereon, and the bracket 206 is connected to the telescopic rod 4, and one end of the telescopic rod 4 corresponds to the piston 101. A buffer pad is installed on the outer surface of the piston 101 to reduce the noise generated when the telescopic rod 4 collides with the piston 101, and at the same time prolong the service life of the piston 101. The outer surfaces of the liquid outlet pipe 103 and the liquid inlet pipe 104 are both installed with a one-way valve, and the working directions of the two one-way valves are opposite to each other, so as to avoid the backflow of liquid and the phenomenon that the device cannot be used.

[0025] By turning the handle provided, the handle drives the incomplete gear 202 to rotate, so that the rack frame 205 drives the slider 204 to move back and forth along the direction of the slide groove 203. The slider 204 drives the telescopic rod 3 to move back and forth through the bracket 206. When the telescopic rod 3 moves toward the piston 101 until it contacts the piston 101, it continues to move, and the telescopic rod 3 pushes the piston 101 to move, thereby squeezing out the material in the sleeve 1.

[0026] Since the rack frame 205 and the incomplete gear 202 have the same size, each time the handle is turned, the handle drives the incomplete gear 202 to rotate, the rack frame 205 moves a distance, and the bracket 206 and the telescopic rod 4 move a distance that is the same. Each time the handle is turned, the weight of the extruded material is the same, which achieves the effect of equal discharge, greatly improving the work efficiency of the staff, and there is no need to repeatedly measure the discharge amount.

[0027] Embodiment 3, the telescopic rod 4 includes an outer mounting column 401 with a hollow interior, a screw rod 402 is rotatably connected between the inner walls of the outer mounting column 401, a threaded sleeve 403 is threadedly connected to the outer surface of the screw rod 402, an inner top plate 404 is fixedly installed on the outer surface of the threaded sleeve 403, a sliding rod 405 is fixedly connected between the inner walls of the outer mounting column 401, a sliding sleeve 406 is sleeved on the outer surface of the sliding rod 405, and the sliding sleeve 406 is connected to the threaded sleeve 403.

[0028] By rotating the screw 402, the threaded sleeve 403 drives the top plate 404 to move along the direction of the slide rod 405, thereby adjusting the distance between the top plate 404 and the piston 101. When the distance is larger, the amount of material extruded each time the handle is rotated is smaller, and vice versa, the amount of material extruded is larger, thereby adjusting the amount of basic material each time, thereby expanding the use of the device.

[0029] To sum up, when the strain adding mechanism is in use, a liquid storage chamber is formed between the piston 101 and the inner wall of the sleeve 1. By pushing the piston 101, the liquid material in the liquid storage chamber is discharged to the working position through the liquid outlet pipe 103, thereby achieving the effect of adding materials. When the piston 101 is released, under the elastic force of the spring 102, the piston 101 moves in the opposite direction, and the material in the storage bottle 3 is drawn into the liquid storage chamber in the sleeve 1 through the liquid inlet pipe 104, thereby achieving the effect of recycling.

[0030] By turning the handle provided, the handle drives the incomplete gear 202 to rotate, so that the rack frame 205 drives the slider 204 to move back and forth along the direction of the slide groove 203. The slider 204 drives the telescopic rod 3 to move back and forth through the bracket 206. When the telescopic rod 3 moves toward the piston 101 until it contacts the piston 101, it continues to move, and the telescopic rod 3 pushes the piston 101 to move, thereby squeezing out the material in the sleeve 1.

[0031] By rotating the screw 402, the threaded sleeve 403 drives the top plate 404 to move along the direction of the slide rod 405, thereby adjusting the distance between the top plate 404 and the piston 101. When the distance is larger, the amount of material extruded each time the handle is rotated is smaller, and vice versa, the amount of material extruded is larger, thereby adjusting the amount of basic material each time, thereby expanding the use of the device.
