[0002] The biomass of aquatic plants is an important indicator for judging the quality of the water ecological environment. The optional categories of aquatic plants include Scirpus validus, Nymphoides peltata, Eichhornia crassipes, Lemna minor, Vallisneria natans, etc. Usually, these aquatic plants are relatively easy to collect. After collection, it is necessary to remove the water attached to the surface of the sample, weigh its wet weight, and then dry the sample by heating and drying to weigh its dry weight, so as to obtain the weight parameters of the aquatic plant sample.

[0003] At present, a centrifugal dryer is used for drying. After drying, all the samples are taken out for wet weight weighing. After weighing, they are sent to a dryer for drying. After drying, they are taken out for weighing again. The process of reciprocally transferring the samples is cumbersome and involves many devices, which is not conducive to the development of experiments. Content of the Utility Model

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a three-chamber collection and weighing device for aquatic plants, which can realize the weighing of the wet weight and dry weight of aquatic plants, reduce the number of sample transfers, and improve the experimental efficiency.

A discharge pipe is arranged at the bottom of the water collecting barrel. A barrel cover is also arranged on the water collecting barrel. A hot air pipe is arranged on the barrel cover. The input end of the hot air pipe is connected to a hot air blower, and the output end of the hot air pipe faces the inner cavity of the drying barrel.

[0007] A base is arranged at the bottom of the weighing base, and a weighing sensor is arranged between the base and the weighing base.

[0008] The drying barrel is sleeved inside the water collecting barrel, and the transmission shaft of the drying barrel passes through the bottom of the water collecting barrel and is in transmission connection with the output end of the driving motor arranged on the weighing base by means of a transmission belt.

A spin cavity is formed inside the spin core cylinder, a drying cavity is formed between the spin core cylinder and the spin outer cylinder, and a discharge cavity is formed between the spin outer cylinder and the water collecting bucket.

[0010] The described spin wheel includes a support wheel disc and a guiding wheel rim in a ring structure. Support rods are arranged between the guiding wheel rim and the support wheel disc. The free end of the guiding wheel rim is in the shape of an outwardly turned flared structure.

Detailed Embodiments

[0019] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments:

[0020] Specific implementation examples Figure 1 and Figure 2 As shown, the present application is a three-chamber collection and weighing device for aquatic plants, comprising a weighing seat 1 and a drying mechanism arranged on the weighing seat 1, the drying mechanism comprising a drying barrel 2 and a driving motor 3 for driving the drying barrel 2 to rotate, a water collecting barrel 4 is arranged outside the drying barrel 2, a discharge pipe 5 is arranged at the bottom of the water collecting barrel 4, an openable and closable barrel cover 6 is further arranged on the water collecting barrel 4, a hot air pipe 7 is arranged on the barrel cover 6, the input end of the hot air pipe 7 is connected to a hot air blower, and the output end of the hot air pipe 7 faces the barrel cavity of the drying barrel 2.

[0021] When the utility model is in use, the collected aquatic plants are put into the drying barrel 2, and the driving motor 3 is powered on to drive the drying barrel 2 to rotate, so that the moisture adhering to the surface of the aquatic plants is dried, thereby facilitating the weighing of the wet weight of the samples. When the aquatic plants need to be dried, the hot air generated by the hot air blower is introduced into the drying barrel 2 with the help of the hot air pipe 7, and the hot air is blown on the samples in the drying barrel 2 to accelerate the drying of the samples, thereby facilitating the acquisition of the dry weight.

[0022] The entire process is completed in the same device, avoiding repeated sample loading and weighing processes and improving experimental efficiency.

[0023] Further, such as Figure 1 As shown, the bottom of the weighing base 1 is provided with a base 8, and a weighing sensor 9 is provided between the base 8 and the weighing base 1. The hot air blower is placed directly on the weighing base 1 or connected to the hot air blower and the hot air pipe 7 via a hose to reduce the impact on the material weighing. The weight measured when the equipment is unloaded is calculated as the tare weight. When the material is loaded, the total weight minus the tare weight is the material mass.

[0024] Furthermore, the spin drying barrel 2 is mounted inside the water collecting barrel 4, and the transmission shaft 202 of the spin drying barrel 2 passes through the bottom of the water collecting barrel 4 and forms a transmission connection with the output end of the driving motor 3 arranged on the weighing seat 1 by means of a transmission belt.

[0025] The spin drying tub 2 is driven by a driving motor 3 provided on the weighing base 1. The driving motor 3 is provided on one side of the spin drying tub 2, which helps to reduce the height of the equipment and improve the stability during spin drying.

[0026] Further, the spin-drying barrel 2 includes a spin-drying wheel 201 and a spin-drying outer cylinder 203. A transmission shaft 202 is connected to the bottom of the spin-drying wheel 201. The spin-drying outer cylinder 203 is in the shape of a cylindrical box. A spin-drying core cylinder 204 is coaxially arranged inside the spin-drying outer cylinder 203. A spin-drying cavity is formed inside the spin-drying core cylinder 204, a drying cavity is formed between the spin-drying core cylinder 204 and the spin-drying outer cylinder 203, and a discharge cavity is formed between the spin-drying outer cylinder 203 and the water collecting bucket 4.

[0027] The spin-drying outer cylinder 203 of the present utility model is detachably inserted on the spin-drying wheel 201. When loading is required, the spin-drying outer cylinder 203 can be taken out, and the collected aquatic plant samples are stuffed into the spin-drying core cylinder 204 inside the spin-drying outer cylinder 203. The diameter of the spin-drying core cylinder 204 is 100 - 150 mm, and its capacity is limited and it is easy to be filled up, so that the aquatic plants avoid large-distance frictional movement during the centrifugal spin-drying process, reduce the breakage of the aquatic plants during the spin-drying process, avoid internal water loss, and ensure relatively high accuracy in wet weight weighing.

[0028] Further, the spin-drying wheel 201 includes a supporting wheel disc 2011 and an annular guiding wheel edge 2012. A supporting rod 2013 is arranged between the guiding wheel edge 2012 and the supporting wheel disc 2011. The free end of the guiding wheel edge 2012 is in the shape of an outwardly turned flared opening.

[0029] Both the spin-drying outer cylinder 203 and the spin-drying inner cylinder have side walls with a mesh structure, which is convenient for water seepage. The guiding wheel edge 2012 being in the shape of a flared opening is convenient for guiding during the installation of the spin-drying outer cylinder 203. The guiding outer cylinder forms a follow-up rotation by means of the frictional force between the guiding wheel edge 2012 and the supporting rod 2013 on the guiding outer cylinder.

[0030] Further, as Figure 3 shown, the spin-drying outer cylinder 203 is provided with a cage cover 205. The cage cover 205 is provided with an inner cover edge 2051 and an outer cover edge 2052. Among them, the inner cover edge 2051 is inserted and fixed with the spin-drying core cylinder 204, and the outer cover edge 2052 is inserted and fixed with the spin-drying outer cylinder 203.

[0031] The cage cover 205 is inserted and fixed with the spin-drying core cylinder 204 through the inner cover edge 2051, so that the upper end of the spin-drying core cylinder 204 can be fixed with the spin-drying outer cylinder 203, avoiding the tremor deformation of the spin-drying core cylinder 204 in the case of uneven sample loading and improving the durability of the equipment.

[0032] Further, the output end of the hot air duct 7 faces the drying core cylinder 204 and is coaxially arranged with the drying core cylinder 204. When drying is required, the sample located in the drying core cylinder 204 is directly transferred into the gap between the drying core cylinder 204 and the outer drying cylinder 203, and hot air is blown into the drying core cylinder 204. Due to the mesh side wall of the drying core cylinder 204, the hot air can blow onto the material attached to the outer drying cylinder 203 by centrifugal force, playing a role in evenly spreading the hot air and improving the drying effect.
