Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 5, the following embodiments of the present invention are provided:
as shown in fig. 1 to 5, a first embodiment of the present invention provides a weighing type pig body height measuring device, at least comprising:
a constraint component 1, wherein the constraint component 1 at least forms a constraint space 101;
The weighing component 2 is arranged at the bottom of the constraint space 101 to obtain the weight of pigs in the constraint space 101;
a height measuring part arranged at one side of the constraint part 1;
wherein the height measuring part at least comprises a main measuring scale 3 and a limiting piece 4;
wherein the limiter 4 limits the movement of the measuring main scale 3 only in a first direction;
wherein the first direction is a vertical direction from top to bottom of the restriction device 1.
In this embodiment, the following consideration is given to the height measurement method in the prior art:
Firstly, the height measurement is carried out while the pig is weighed by the operator, but as mentioned above, because the pig is a living animal, the height measurement posture is difficult to control by people, and the operator is required to constantly strike the back of the pig to force the pig to be adjusted to the normal posture (i.e. the head is not lifted higher or lower and the back is not raised or collapses). However, when the forced action is performed, pigs are more likely to generate stress reaction and generate larger action.
Secondly, the head of the pig can be lifted by arranging the head lifting structure, so that the pig can be adjusted to the normal posture. However, on the one hand, the increase of the structure can bring complicated operation, and a large amount of pigs are measured in a large pig farm every day, so that the method is time-consuming and labor-consuming, and on the other hand, the problem of inaccurate back height measurement is difficult to solve fundamentally.
Based on the above, the purpose of the embodiment is to capture and freeze the standard improvement of the normal posture of the pig to be tested on the basis of not adding any auxiliary structure and auxiliary operation, so as to improve the accuracy and convenience of measurement.
Therefore, the restraint part 1 is used for providing a restraint space 101, and after the pig to be tested only enters the restraint space 101, the pig to be tested is firstly measured by the weighing part 2 (weighing scale) to obtain the weight of the pig to be tested.
The height measurement device is used for measuring the height of the pig to be measured, and as mentioned above, because the posture of the pig is difficult to be controlled manually, the embodiment aims to capture and freeze the height of the pig at the moment of normal posture, so that the height measurement device is optimized:
The main measuring scale 3 of the height measuring part can be restrained by the restraining piece 4, and can only act along the first direction by the gravity factor of the main measuring scale 3, wherein the first direction is the vertical direction from the top to the bottom of the restraining piece, so that when the pig is in an abnormal posture, the main measuring scale 3 is abutted against the back of the pig by the gravity factor, and the main measuring scale 3 does not act in the directions except the first direction, especially in the opposite direction along with the action of the pig, even if the pig only bulges the back again, due to the restraining action of the main measuring scale 3, the pig can not complete the action. Until the pig is restored to the normal posture at a certain moment, the measurement main scale 3 can descend along with the back of the pig due to gravity at the moment due to the limiting effect of the limiting piece 4, so that the standard height of the pig in the normal posture at the moment is obtained, and the accuracy of high measurement is ensured.
Therefore, the limiting piece 4 can capture and freeze the standard body of the pig in the normal posture by the main measurement ruler 3, so that on one hand, operators can conveniently read the numerical value of the standard body, on the other hand, the accuracy of the measurement of the pig body is ensured, the interference of the abnormal posture of the pig body or the inaccurate numerical value in the active state is eliminated, the manual intervention on the posture of the pig body is not needed, and the convenience of the measurement of the body is ensured.
As shown in fig. 1 to 4, a second embodiment of the present invention provides a weighing type pig body height measuring device, and on the basis of the first embodiment, the measuring main scale 3 at least includes:
a scale 301 and a overhang scale 302;
Wherein the scale 301 is disposed on the constraint component 1 along the first direction;
wherein the suspension rule 302 is slidingly connected to the calibration rule 301;
wherein the scale 301 has a dimension line;
wherein, the suspension ruler 302 is provided with an indication surface 3021 which can be contacted with the back of the pig to be tested;
the indication surface 3021 is indicated in such a manner that the size of the size line is higher than the size of the pig to be tested.
In this embodiment, the indication surface 3021 is used to keep the back of the pig in contact with the present pig body. After the standard height of the pig in the normal posture is obtained, the reading of the size line of the indication surface 3021 can be used for obtaining the height data of the pig.
Wherein the scale 301 is arranged in a first direction, i.e. in correspondence with the height direction of the restriction member 1, the suspension scale 302 is slidingly connected to the scale 301 and it can be restricted by the restriction member 4 to act only in the first direction. The hanging ruler 302 ensures that the indication surface 3021 of the hanging ruler always contacts with the back of the pig through self weight.
As shown in fig. 5, a third embodiment of the present invention provides a weighing type pig body height measuring device, and based on the above embodiment, the limiting member 4 at least includes:
a first engagement portion 401 and a second engagement portion 402;
Wherein, the first engagement portion 401 is disposed on the calibration ruler 301;
Wherein the second engagement portion 402 is disposed on the suspension rule 302;
and, the first engagement part 401 is unidirectionally engaged with the second engagement part 402;
Wherein the unidirectional engagement is at least: allowing only the suspension rule 302 to act with a controlled gravitational force in a first direction.
In the present embodiment, the restriction member 4 includes an engagement portion 401 and an engagement portion 402.
The first engagement part 401 and the second engagement part 402 form one-way engagement, that is, the hanging ruler 302 can only act along the first direction due to gravity, so that the standard height of the obtained pig in the normal posture is ensured.
As shown in fig. 5, a fourth embodiment of the present invention provides a weighing type pig body height measuring device, and based on the above embodiment, the limiting member 4 further includes:
An unlocking structure connected with the second engagement part 402;
Wherein the unlocking feature is configured to disengage the unidirectional engagement to allow the suspension rule 302 to move in a second direction;
And, the second direction is opposite to the first direction.
In this embodiment, it has further been found that if the suspended rule 302 can only be moved in the first direction, it cannot be restored to the initial point, and therefore, when the next pig to be tested is measured for height, the suspended rule 302 at the non-initial point cannot be brought into contact with the back of the pig more accurately.
Based on this, an unlocking structure is added. The unlocking structure can contact the unidirectional meshing to ensure that the suspension ruler 302 can act along the second direction, so that the suspension ruler can rise to an initial point position to perform the height measurement of the next pig to be tested.
As shown in fig. 5, a fifth embodiment of the present invention provides a weighing type pig body height measuring device, and based on the above embodiment, the first engagement portion 401 is a ratchet, and the second engagement portion 402 is a pawl;
Wherein the ratchet teeth are arranged along the first direction;
wherein, the pawl and the ratchet form one-way meshing connection.
In this embodiment, the specific structures of the first engagement portion 401 and the second engagement portion 402 are defined.
Wherein the pawl and ratchet are unidirectionally engaged to ensure that the suspended rule 302 can only be moved in a first direction. Of course, the above is only one of the unidirectional engagement connection modes, and the structure is relatively simple and convenient to operate. It is within the scope of the disclosure and protection of this embodiment to also take the remaining form of construction.
As shown in fig. 5, a sixth embodiment of the present invention provides a weighing type pig body height measuring device, and based on the above embodiment, the unlocking structure includes:
A chamber 503, an elastic member 501, and a driving member 502;
Wherein the cavity 503 is formed by the overhanging ruler 302;
Wherein the driver 502 is slidably connected to the chamber 503 and an end is connected to the pawl;
wherein the elastic member 501 is disposed in the cavity 503 and forms a clearance fit with the driving member 502;
and, one end of the elastic member 501 abuts against the inner wall surface of the cavity 503, and the other end abuts against the pawl, so as to provide a force for unidirectional engagement with the ratchet teeth to the pawl;
Wherein the driving member 502 is at least controlled by an external force to cause the pawl and the ratchet to disengage.
In the present embodiment, the unlocking structure is defined.
In actual operation, the present embodiment is expected to avoid the occurrence of electric components because of the potential risk of damage to pigs, such as electrical leakage, etc. In addition, the present embodiment also expects that the simpler and better the operation, the more efficient and better.
Based on this, the unlocking structure employs a chamber 503, an elastic member 501, and a driving member 502.
The cavity 503 is a cavity structure formed by a portion of the overhanging ruler 302 protruding, the elastic member 501 is a spring, and the driving member 502 is a driving rod.
In the absence of any external force, the two ends of the elastic member 501 respectively abut against the inner side wall surface of the cavity 503 and the end of the pawl, which is in a compressed state, and thereby provides a force for the pawl to engage with the ratchet teeth.
When unlocking is required, an operator pulls the driving member 502, so that the driving member 502 drives the pawl to move in a direction away from the ratchet (because the external force is greater than the elastic force of the elastic member 501, the elastic member 501 is further compressed), and the pawl is not engaged with the ratchet any more, and the suspension ruler 302 is in a free state, and in this state, the suspension ruler can move along the second direction. When the operator releases the driver 502, the pawl and ratchet tooth re-engagement is achieved as described above.
As shown in fig. 2, a seventh embodiment of the present invention provides a weighing type pig body height measurement device, and based on the above embodiment, the suspension ruler 302 at least includes:
A sliding portion 3022 and an overhang portion 3023;
wherein the sliding portion 3022 is slidably connected to the scale 301;
Wherein the overhang portion 3023 is connected to the sliding portion 3022;
Wherein the weight of the sliding portion 3022 is g1, the weight of the overhang portion 3023 is g2, and:
g1=K1×g2；
The value range of K1 is: 1.3 to 1.9.
In the present embodiment, the sliding portion 3022 may be in the form of a sliding sleeve, and the overhang portion 3023 may be in the form of a solid plate or block. The sliding portion 3022 is connected to the scale 301 to ensure that the overhang portion 3023 is moved in the first direction.
On the basis of the above, it has further been found that since the present embodiment requires the suspension rule 302 to descend by its own weight, smoothness of sliding between the sliding portion 3022 and the scale 301 needs to be ensured. The form of the socket necessarily results in a gap between the sliding portion 3022 and the scale 301 which further results in the hanging scale 302 sliding downwardly with a risk of jamming, and thus a relatively inaccurate pig height acquisition.
Based on this, the weights of the sliding portion 3022 and the overhang portion 3023 are defined in association. If the weight of the sliding portion 3022 is too large to cause a rapid falling speed if the weight exceeds the above-mentioned limit range, a large force is applied to the back of the pig, so that the pig to be tested is forced to excessively fall down the waist due to stress reaction, and thus high accuracy cannot be ensured. If it is smaller than the above-defined range, the weight of the overhang portion 3023 will be excessively large, so that the gravity center of the overhang portion 3023 of the overhang ruler 302 will be less expensive, and the sliding portion 3022 will be extremely likely to be jammed.
As shown in fig. 1, an eighth embodiment of the present invention provides a weighing type pig body height measurement device, and further includes, based on the previous embodiment:
A rotating member 6 provided between the height measuring member and the restraining member 1;
Wherein the rotation member 6 is configured to allow rotation of the height finding member along its axis.
In this embodiment, since the body width direction of the suspended rule 302 is consistent with that of the pig to be measured in the measurement state, after the measurement is completed, in order to avoid interference when the suspended rule 302 and the next pig to be measured enter, the rotating member 6 is added so that the suspended rule 302 can rotate, or the measurement main rule 3 can integrally rotate, so as to ensure that the body length direction of the suspended rule 302 is consistent with that of the pig to be measured. Specifically, the rotating member 6 is in the form of a rotating shaft which is provided at the bottom of the scale 301 and constitutes a rotational connection with the restricting member 1.
A ninth embodiment of the present invention provides a weighing type pig body height measuring apparatus, and on the basis of the above embodiment, the restraint part 1 at least includes:
a fence 102, the fence 102 constituting the constraint space 101;
The width of the constraint space 101 is W1, the body width of the pig to be tested is W2, and:
W1=K2×W2;
The value range of K2 is: 1.1 to 1.3.
In this embodiment, the restricting member 1 is a rail 102. One end of the fence 102 is used as an inlet, and the other end is used as an outlet for the entry and exit of pigs to be tested.
It is further found that the body parameters of the pigs to be tested in the same batch are relatively close because the feeding period is usually close when the pigs are at height measurement, so that the width of the constraint space 101 can be adjusted according to the average value of the body widths of the pigs to be tested in the batch.
When the width of the constraint space 101 is within the above range, it can be ensured that the pig can not turn around in the constraint space 101, so that the activity space is limited, and the inaccuracy of the measurement structure caused by excessive action of the pig can be avoided.
